Emergence From Voluntary Reorganization Under Chapter 11 Of The Bankruptcy Code [Abstract]

Emergence From Voluntary Reorganization Under Chapter 11 Of The Bankruptcy Code

2. EMERGENCE FROM VOLUNTARY REORGANIZATION UNDER CHAPTER 11 OF THE BANKRUPTCY CODE

On March 16, 2009, Primus Telecommunications Group, Incorporated ("Group" or "PTGI") and three of its subsidiaries, Primus Telecommunications Holding, Inc. ("Holding" or "PTHI"), Primus Telecommunications International, Inc. ("PTII") and Primus Telecommunications IHC, Inc., ("IHC" and together with Group, Holding and PTII, collectively, the "Debtors") each filed a voluntary petition (the "Chapter 11 Cases") in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court") for reorganization relief ("Reorganization") under chapter 11 of title 11 of the United States Code, 11 U.S.C. §§ 101 et seq., as amended (the "Bankruptcy Code"). Subsequently, the Debtors sought and received an order directing the joint administration of the Chapter 11 Cases under the caption In re: Primus Telecommunications Group, Incorporated, et al., Debtors, Case No. 09-10867. On April 8, 2009, April 20, 2009, and April 24, 2009, filings were made by the Debtors in the Bankruptcy Court concerning amended Disclosure Statements and Joint Plans of Reorganization of Primus Telecommunications Group, Incorporated and its Affiliate Debtors. On April 24, 2009, an unsecured creditors' committee was appointed by the United States Trustee.

On April 27, 2009, the Bankruptcy Court approved the Debtors' use of a disclosure statement dated April 27, 2009 (the "Disclosure Statement") to solicit votes on the Joint Plan of Reorganization of Primus Telecommunications Group, Incorporated and its Affiliate Debtors attached thereto (the "Plan"). The Disclosure Statement was distributed to holders of record (as of April 27, 2009) of claims against, and interests in, the Debtors who are entitled to vote on the Plan (the "Record Date").

The order approving the Disclosure Statement also (i) established the Record Date and a voting deadline of June 5, 2009, (ii) established June 5, 2009 as the last date and time for filing and serving objections to confirmation of the Plan (and related requirements and procedures set forth in such order), and (iii) fixed June 1, 2009 as the deadline for claimants and interest holders to file and serve motions under Bankruptcy Rule 3018(a) requesting temporary allowance of the movant's claim or interest for purposes of voting.

The Plan was confirmed by the Bankruptcy Court on June 12, 2009 (the "Confirmation Date"). On July 1, 2009 (the "Effective Date"), the Debtors consummated their reorganization under the Bankruptcy Code and the Plan became effective.

The Plan provided for a plan of reorganization of the Debtors on terms that are summarized below:

•

Holding's Term Loan facility due February 2011 was reinstated and amended;

•

IHC's 14¹/4% Senior Secured Notes were cancelled and the holders thereof received (a) their pro rata portion of $123.5 million of aggregate principal amount of 14¹/4% Senior Subordinated Secured Notes due May 20, 2013, (b) 4,800,000 shares of the new Common Stock of Group (the "New Common Stock"), and (c) all reasonable fees, expenses and disbursements of their counsel;

•

the 5% Exchangeable Senior Notes and 8% Senior Notes issued by Holding (collectively, the "Holding Senior Notes") were cancelled, and the holders thereof received (a) 4,800,000 shares of the New Common Stock, (b) Class A warrants to purchase up to an aggregate of 3,000,000 shares of New Common Stock on terms described below under "Warrant Agreements," and (c) all reasonable fees, expenses and disbursements of their counsel;

•

the 3³/4% Senior Notes due September 2010, 12 ³/4% Senior Notes due October 2009 and Step Up Convertible Subordinated Debentures due August 2009 issued by Group (collectively, the "Group Notes") were cancelled, and the holders thereof received Class B warrants to purchase up to an aggregate of 1,500,000 shares of the New Common Stock on terms described below under "Warrant Agreements;"

•

all existing shares of common stock outstanding prior to the Effective Date (the "Old Common Stock") were cancelled on the Effective Date, and holders thereof received their pro rata share of contingent value rights ("Contingent Value Rights" or "CVRs") to acquire up to 2,665,000 shares of New Common Stock on terms described below under "Contingent Value Rights Distribution Agreement;" and

•

all outstanding equity incentive grants of Group were cancelled on the Effective Date, and the Primus Telecommunications Group, Incorporated Management Compensation Plan (the "Management Compensation Plan") became effective. As of the Effective Date, 400,000 restricted stock units, 387,403 service-based stock options and 100,000 performance-based stock options were granted to certain employees and executive officers under the Management Compensation Plan.

The following table summarizes the effect of the Plan of Reorganization adjustments with respect to long-term obligations after giving effect to the July 1, 2009 emergence from bankruptcy.

As of the Effective Date, Group issued Class A warrants to purchase up to an aggregate of 3,000,000 shares of New Common Stock to holders of the Holding Senior Notes. The Class A warrants consist of 1,000,000 each of Class A-1 warrants, Class A-2 warrants and Class A-3 warrants. In connection with the issuance of the Class A warrants, Group entered into a warrant agreement, dated as of the Effective Date (the "Class A Warrant Agreement"), with Broadridge Corporate Issuer Solutions, Inc., as warrant agent.

In addition, a holder may exercise Class A warrants on a cashless basis in connection with a change of control (as defined in the Class A Warrant Agreement), in connection with a transaction pursuant to an effective registration statement covering the sale of New Common Stock underlying such Class A warrants, or if the exercise occurs on a date when the daily volume-weighted average price of the New Common Stock for the immediately preceding 10 trading days exceeds 150% of the exercise price applicable to such Class A warrants. The Class A warrants are freely transferrable by the holder thereof.

As of the Effective Date, Group issued Class B warrants to purchase up to an aggregate of 1,500,000 shares of New Common Stock to holders of the Group Notes.

The Class B warrants have a five-year term and will expire on July 1, 2014. A holder may exercise Class B warrants by paying the applicable exercise price in cash. In addition, a holder may exercise Class B warrants on a cashless basis in connection with a change of control (as defined in the Class B Warrant Agreement), in connection with a transaction pursuant to an effective registration statement covering the sale of New Common Stock underlying such Class B warrants, or if the exercise occurs on a date when the daily volume-weighted average price of the New Common Stock for the immediately preceding 10 trading days exceeds 150% of the exercise price applicable to the Class B warrants. The Class B warrants are freely transferrable by the holder thereof.

The number of shares of New Common Stock issuable upon exercise of the Class A warrants and Class B warrants (together, the "Warrants") and the exercise prices of the Warrants will be adjusted in connection with any dividend or distribution of New Common Stock, assets or cash (other than any regular cash dividend not to exceed in any fiscal year 45% of the consolidated net income of Group), or any subdivision or combination of the New Common Stock. In addition, the number of shares of New Common Stock issuable upon exercise of the Warrants and the exercise prices of the Warrants are also subject to adjustment in connection with any issuance, grant or sale to any person of (A) rights, warrants, options, exchangeable securities or convertible securities entitling such person to subscribe for, purchase or otherwise acquire shares of New Common Stock at a price per share less than the fair market value of the New Common Stock on the trading day immediately prior to such issuance, sale or grant, subject to certain exceptions, or (B) shares of New Common Stock at a price per share less than the fair market value of the New Common Stock on the trading day immediately prior to such issuance, sale or grant. Additionally, if any transaction or event occurs in which all or substantially all of the outstanding New Common Stock is converted into, exchanged for, or the holders thereof are otherwise entitled to receive on account thereof stock, other securities, cash or assets (each, a "Fundamental Change Transaction") the holder of each Warrant outstanding immediately prior to the occurrence of such Fundamental Change Transaction shall have the right to receive upon exercise of the applicable Warrant the kind and amount of stock, other securities, cash and/or assets that such holder would have received if such Warrant had been exercised.

The Company recorded $1.0 million of equity related to the issuance of the warrants as of July 31, 2009, as part of the emergence from bankruptcy.

Contingent Value Rights Distribution Agreement

Pursuant to the terms of the Plan, Group issued to holders of Group's Old Common Stock Contingent Value Rights to receive up to an aggregate of 2,665,000 shares (the "CVR Shares") of New Common Stock. In connection with the issuance of the Contingent Value Rights, Group entered into a Contingent Value Rights Distribution Agreement (the "CVR Agreement"), in favor of holders of CVRs thereunder, dated as of the Effective Date.

The CVRs may not be transferred by the holder thereof except in certain limited circumstances. Subject to the terms of the CVR Agreement, holders of CVRs will receive their pro rata share of up to 2,665,000 CVR Shares if certain conditions are satisfied. A distribution of CVR Shares is required to be made by Group if, as of any determination date (as described in the paragraph below), Group's equity value (assuming cash exercise in full on such date of in-the-money warrants and options of Group) divided by the sum of the number of shares of New Common Stock then issued and outstanding plus the number of shares of New Common Stock underlying warrants, options and similar securities of Group (other than CVRs) that are then in-the-money exceeds $35.95. The aggregate number of such shares of New Common Stock is referred to as the "Applicable Shares;" the price per share of $35.95, subject to adjustment as described below, is referred to as the "CVR Strike Price;" and the per share amount of any such excess over the CVR Strike Price is referred to as the "Excess Equity Value Per Share." If such a distribution is required, the number of CVR Shares to be distributed by Group equals the product of Excess Equity Value Per Share multiplied by the number of Applicable Shares divided by the CVR Strike Price. Such product of Excess Equity Value Per Share and the number of Applicable Shares is referred to as the "Excess Equity Value."

Group will determine if and to the extent a distribution of CVR Shares is required (i) on January 1 and July 1 of each year, commencing on the first such date (but in no event later than July 1, 2013) on which data is available to confirm that Group's adjusted EBITDA for the immediately preceding four fiscal quarters is equal to at least $100 million, and (ii) upon the occurrence of certain change of control transactions involving Group. Distributions of CVR Shares (if any) will be made within 45 calendar days of a determination by Group that a distribution is required.

Notwithstanding the foregoing, no distribution of CVR Shares is required to be made by Group unless Excess Equity Value exceeds $1 million as of any determination date.

The maximum number of CVR Shares and the CVR Strike Price will be adjusted from time to time in connection with any stock dividend or distribution, or subdivision, split, combination, reclassification or recapitalization of the New Common Stock. In addition, if Group distributes to holders of New Common Stock any of its assets (including but not limited to cash), securities or rights to purchase securities of Group (other than any regular cash dividend not to exceed in any fiscal year 45% of the consolidated net income of Group for the immediately preceding fiscal year), then the number of CVR Shares will be increased and the CVR Strike Price will be decreased, in each case pursuant to the terms of the CVR Agreement. Additionally, in case of any reclassification, merger, consolidation, capital reorganization or other change in the capital stock of Group (other than in connection with certain change of control transactions involving Group) in which all or substantially all of the outstanding shares of New Common Stock are converted into or exchanged for stock, other securities or other property, Group shall make appropriate provision so that the holders of Contingent Value Rights shall thereafter be entitled to receive, at such time such holder would have otherwise been entitled to receive a distribution under the CVR Agreement, the kind and amount of stock and other securities and property having a value substantially equivalent to the value of New Common Stock that the holders of Contingent Value Rights would have been entitled to receive in connection with a distribution of CVR Shares immediately prior to such reclassification, merger, consolidation, reorganization or other change in the capital stock of Group at a CVR Strike Price that, in each case, is reasonably determined by the board of directors of Group after consultation with an independent valuation advisor to preserve, to the extent practicable, the intrinsic value of such CVR immediately prior to such event.

The Contingent Value Rights will expire and the CVR Agreement will terminate upon the earliest to occur of: (1) the date upon which no further CVR Shares are available for distribution, (2) the consummation of a certain change of control transactions (subject to any potential distribution of CVR Shares as a result thereof), and (3) July 1, 2019.

Due to the nature of the CVRs, the Company accounted for the instrument in accordance with ASC No. 815, "Derivatives and Hedging", as well as related interpretations of these standards. The Company recorded a liability of $2.6 million in other liabilities as part of fresh-start accounting, and will adjust the liability to its estimated fair value. The change in value is reflected in our Statements of Operations as other income (expense). See Note 10—"Fair Value of Financial Instruments and Derivatives".

Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation—The consolidated financial statements include the Company's accounts, its wholly-owned subsidiaries and all other subsidiaries over which the Company exerts control. The Company owns 45.6% of Globility Communications Corporation ("Globility") through direct and indirect ownership structures. Globility paid a dividend in April 2011, of which $1.2 million was attributable to the noncontrolling interest shareholder. The results of Globility and its subsidiary are consolidated with the Company's results based on guidance from the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") No. 810, "Consolidation" ("ASC 810"). All intercompany profits, transactions and balances have been eliminated in consolidation. ASC No. 810 changed the presentation of outstanding noncontrolling interests in one or more subsidiaries or the deconsolidation of those subsidiaries. Discontinued Operations—During 2011, the Company sold its Brazilian segment. The Company has applied retrospective adjustments for 2010 and 2009 to reflect the effects of the discontinued operations that occurred subsequent to December 31, 2010. Accordingly, revenue, costs, and expenses of the discontinued operations have been excluded from the respective captions in the consolidated statements of operations. See Note 20, "Discontinued Operations," for further information. During 2010, the Company classified its European retail operations as discontinued operations. The Company has applied retrospective adjustments for 2009 to reflect the effects of the discontinued operations that occurred subsequent to December 31, 2009. Accordingly, revenue, costs, and expenses of the discontinued operations have been excluded from the respective captions in the consolidated statements of operations. See Note 20, "Discontinued Operations," for further information. During 2009, the Company sold certain assets of its Japan retail operations. The Company intended and had the authority to sell certain assets of its Japan retail operations since the fourth quarter of 2008, and therefore, reported this unit as discontinued operations. Reorganization Costs—In accordance with ASC No. 852, "Reorganizations," for periods including and subsequent to the filing of the Chapter 11 petition through the bankruptcy emergence date of July 1, 2009, all revenues, expenses, realized gains and losses, and provisions for losses that result from the reorganization were reported separately as reorganization items, net, in the consolidated statements of operations. Net cash used for reorganization items was disclosed separately in the consolidated statements of cash flows. Fresh-Start—As of July 1, 2009, the Company adopted fresh-start accounting in accordance with ASC No. 852. The adoption of fresh-start accounting resulted in the Company becoming a new entity for financial reporting purposes. Accordingly, the financial statements on or prior to July 1, 2009 are not comparable with the financial statements for periods after July 1, 2009. The consolidated statements of operations, comprehensive income (loss) and any references to "Successor" or "Successor Company" for the years ended December 31, 2011 and 2010, and for the six months ended December 31, 2009, show the operations of the reorganized Company from and including July 1, 2009, the Effective Date. References to "Predecessor" or "Predecessor Company" refer to the operations of the Company prior to July 1, 2009, except for Predecessor's July 1, 2009 statements of operations and comprehensive income (loss), which reflect only the effect of the plan adjustments and fresh-start accounting as of such date and do not reflect any operating results. See Note 4—"Fresh-Start Accounting," for further details. Revenue Recognition and Deferred Revenue—Net revenue is derived from carrying a mix of business, residential and carrier long distance traffic, data and Internet traffic, and also from the provision of hosting, local and wireless services. For certain voice services, net revenue is earned based on the number of minutes during a call and is recorded upon completion of a call. Revenue for a period is calculated from information received through the Company's network switches. Customized software has been designed to track the information from the switch and analyze the call detail records against stored detailed information about revenue rates. This software provides the Company the ability to do a timely and accurate analysis of revenue earned in a period. Separate prepaid services software is used to track additional information related to prepaid service usage such as activation date, monthly usage amounts and expiration date. Revenue on these prepaid services is recognized as service is provided until expiration, when all unused minutes, which are no longer available to the customers, are recognized as revenue. Net revenue is also earned on a fixed monthly fee basis for unlimited local and long distance voice plans and for the provision of data/Internet services (including retail VOIP), hosting, and colocation. Data/Internet services include monthly fees collected for the provision of dedicated and dial-up access at various speeds and bandwidths. These fees are recognized as access is provided on a monthly basis. Additionally, service activation and installation fees are deferred and amortized over the longer of the average customer life or the contract term. The Company records payments received in advance for services and services to be provided under contractual agreements, such as Internet broadband, dial-up access, hosting, and colocation, as deferred revenue until such related services are provided. In the United States, we charge customers Federal Universal Service Fund ("USF") fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. Net revenue represents gross revenue, net of allowance for doubtful accounts receivable, service credits and service adjustments. Presentation of Taxes Collected—The Company reports any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between the Company and a customer (including sales, use, value-added and some excise taxes) on a net basis (excluded from revenues). Cost of Revenue—Cost of revenue includes network costs that consist of access, transport and termination costs. The majority of the Company's cost of revenue is variable, primarily based upon minutes of use, with transmission and termination costs being the most significant expense. Cost of revenue also includes fees such as Federal USF fees. Such costs are recognized when incurred in connection with the provision of telecommunications services. Foreign Currency Transactions—Foreign currency transactions are transactions denominated in a currency other than a subsidiary's functional currency. A change in the exchange rates between a subsidiary's functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is reported by the Company as a foreign currency transaction gain (loss). The primary component of the Company's foreign currency transaction gain (loss) is due to agreements in place with certain subsidiaries in foreign countries regarding intercompany transactions. The Company anticipates repayment of these transactions in the foreseeable future, and recognizes the realized and unrealized gains or losses on these transactions that result from foreign currency changes in the period in which they occur as foreign currency transaction gain (loss). Income Taxes—The Company recognizes income tax expense for financial reporting purposes following the asset and liability approach for computing deferred income taxes. Under this method, the deferred tax assets and liabilities are determined based on the difference between financial reporting and tax bases of assets and liabilities based on enacted tax rates. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company applies the uncertain tax position-related provisions of ASC No 740 "Income Taxes" (formerly FIN No. 48, "Accounting for Uncertainty in Income Taxes"). These provisions clarify the accounting for uncertainty in income taxes recognized in the financial statements in accordance with ASC No. 740. Foreign Currency Translation—The assets and liabilities of the Company's foreign subsidiaries are translated at the exchange rates in effect on the reporting date. Income and expenses are translated at the average exchange rate during the period. The net effect of such translation gains and losses are reflected within accumulated other comprehensive income (loss) in the stockholders' equity (deficit) section of the balance sheet. Cash and Cash Equivalents—Cash and cash equivalents are comprised principally of amounts in money market accounts, operating accounts, certificates of deposit, and overnight repurchase agreements with original maturities of three months or less. Restricted Cash—Restricted cash consists of bank guarantees and certificates of deposit utilized to support letters of credit and contractual obligations. Accounts Receivable—Accounts receivable are stated at amounts due from customers net of an allowance for doubtful accounts. Our allowance for doubtful accounts considers historical experience, the age of certain receivable balances, current economic conditions and other factors that may affect the counterparty's ability to pay. Advertising Costs—In accordance with ASC No. 720-35, "Other Expenses—Advertising," costs for advertising are expensed as incurred. Advertising expense for the years ended December 31, 2011 and 2010 and the six months ended December 31, 2009 and July 1, 2009 was $12.9 million, $11.9 million, $8.2 million and $5.2 million, respectively. Property and Equipment—Property and equipment are recorded at cost less accumulated depreciation, which is provided on the straight-line method over the estimated useful lives of the assets. Cost includes major expenditures for improvements and replacements which extend useful lives or increase capacity of the assets as well as expenditures necessary to place assets into readiness for use. Expenditures for maintenance and repairs are expensed as incurred. The estimated useful lives of property and equipment are as follows: network equipment—5 to 8 years, fiber optic and submarine cable—8 to 25 years, furniture and equipment—5 years, and leasehold improvements and leased equipment—shorter of lease or useful life. Costs for internal use software that are incurred in the preliminary project stage and in the post-implementation stage are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. Fiber Optic and Submarine Cable Arrangements—The Company obtains capacity on certain fiber optic and submarine cables under three types of arrangements. The Indefeasible Right of Use ("IRU") basis provides the Company the right to use a cable for the estimated economic life of the asset according to the terms of the IRU agreement with most of the rights and duties of ownership. The Minimum Assignable Ownership Units ("MAOU") basis provides the Company an ownership interest in the fiber optic cable with certain rights to control and to manage the facility. The Company accounts for both IRU and MAOU agreements under network equipment and depreciates the recorded asset over the term of the agreement which is generally 25 years. The Company also enters into shorter-term arrangements with other carriers which provide the Company the right to use capacity on a cable but without any rights and duties of ownership. Under these shorter-term arrangements, the costs are expensed in the period the services are provided. Business Combinations—The Company is required to allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. This valuation requires management to make significant estimates and assumptions, especially with respect to intangible assets associated with such assets. Critical estimates in valuing certain of the intangible assets and subsequently assessing the realizability of such assets include, but are not limited to, future expected cash flows from the revenues, customer contracts and discount rates. Management's estimates of fair value are based on assumptions believed to be reasonable but which are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate and unanticipated events and circumstances may occur. Other estimates associated with the accounting for these acquisitions and subsequent assessment of impairment of the assets may change as additional information becomes available regarding the assets acquired and liabilities assumed. Goodwill and Other Intangible Assets—Under ASC No. 350, "Intangibles—Goodwill and Other" ("ASC 350"), goodwill and indefinite lived intangible assets are not amortized but are reviewed annually for impairment, or more frequently, if impairment indicators arise. Intangible assets that have finite lives are amortized over their estimated useful lives and are subject to the provisions of ASC No. 360, "Property, Plant and Equipment" ("ASC 360"). Goodwill impairment is tested at least annually (October 1 for the Company) or when factors indicate potential impairment using a two-step process that begins with an estimation of the fair value of each reporting unit. Step 1 is a screen for potential impairment by comparing the fair value of a reporting unit with its carrying amount. The estimated fair value of each reporting unit is compared to its carrying value. The Company estimates the fair values of each reporting unit by a combination of (i) estimation of the discounted cash flows of each of the reporting units based on projected earnings in the future (the income approach) and (ii) a comparative analysis of revenue and EBITDA multiples of public companies in similar markets (the market approach). If there is a deficiency (the estimated fair value of a reporting unit is less than its carrying value), a Step 2 test is required. Step 2 measures the amount of impairment loss, if any, by comparing the implied fair value of the reporting unit goodwill with its carrying amount. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination is determined; through an allocation of the fair value of a reporting unit to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. The Company's reporting units are the same as its operating segments, except as discussed in Note 7 related to Arbinet, as each segment's components have been aggregated and deemed a single reporting unit because they have similar economic characteristics. Each component is similar in that each provides telecommunications services for which all of the resources and costs are drawn from the same pool, and are evaluated using the same business factors by management. Estimating the fair value of a reporting unit requires various assumptions including projections of future cash flows, perpetual growth rates and discount rates. The assumptions about future cash flows and growth rates are based on the Company's assessment of a number of factors, including the reporting unit's recent performance against budget, performance in the market that the reporting unit serves, and industry and general economic data from third party sources. Discount rate assumptions are based on an assessment of the risk inherent in those future cash flows. Changes to the underlying businesses could affect the future cash flows, which in turn could affect the fair value of the reporting unit. Intangible assets not subject to amortization consist of certain trade names. Such indefinite lived intangible assets are tested for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test shall consist of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value an impairment loss shall be recognized in an amount equal to the excess. Intangible assets subject to amortization consist of certain trade names and customer relationships. These finite lived intangible assets are amortized based on their estimated useful lives. Such assets are subject to the impairment provisions of ASC 360, wherein impairment is recognized and measured only if there are events and circumstances that indicate that the carrying amount may not be recoverable. The carrying amount is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use of the asset group. An impairment loss is recorded if after determining that it is not recoverable, the carrying amount exceeds the fair value of the asset. Valuation of Long-Lived Assets—The Company reviews long-lived assets whenever events or changes indicate that the carrying amount of an asset may not be recoverable. In making such evaluations, the Company compares the expected undiscounted future cash flows to the carrying amount of the assets. If the total of the expected undiscounted future cash flows is less than the carrying amount of the assets, the Company is required to make estimates of the fair value of the long-lived assets in order to calculate the impairment loss equal to the difference between the fair value and carrying value of the assets. The Company makes significant assumptions and estimates in this process regarding matters that are inherently uncertain, such as determining asset groups and estimating future cash flows, remaining useful lives, discount rates and growth rates. The resulting undiscounted cash flows are projected over an extended period of time, which subjects those assumptions and estimates to an even larger degree of uncertainty. While the Company believes that its estimates are reasonable, different assumptions could materially affect the valuation of the long-lived assets. The Company derives future cash flow estimates from its historical experience and its internal business plans, which include consideration of industry trends, competitive actions, technology changes, regulatory actions, available financial resources for marketing and capital expenditures and changes in its underlying cost structure. The Company has concluded that it has one asset group: the network. This is due to the nature of its telecommunications network which utilizes all of the points of presence (POPs), switches, cables and various other components throughout the network to form seamlessly the telecommunications gateway over which its products and services are carried for any given customer's phone call or data or Internet transmission. Furthermore, outflows to many of the external network providers are not separately assignable to revenue inflows for any phone call or service plan. The Company makes assumptions about the remaining useful life of its long-lived assets. The assumptions are based on the average life of its historical capital asset additions, its historical asset purchase trend and that its primary assets, its network switches, have an 8-year life. Because of the nature of its industry, the Company also assumes that the technology changes in the industry render all equipment obsolete with no salvage value after their useful lives. In certain circumstances in which the underlying assets could be leased for an additional period of time, the Company includes such estimated cash flows in its estimate. The estimate of the appropriate discount rate to be used to apply the present value technique in determining fair value was the Company's weighted average cost of capital which is based on the effective rate of its long-term debt obligations at the current market values as well as the current volatility and trading value of the Company's common stock. Deferred Financing Costs—Deferred financing costs incurred in connection with financing arrangements are reflected within other assets and are amortized over the life of the respective financing arrangements using the effective interest method. As the Company completes debt transactions, corresponding amounts of deferred financing costs are written-off in determining the gain or loss on early extinguishment or restructuring of debt. Derivative Instruments—Pursuant to the terms of the Company's 2009 bankruptcy reorganization (the "Reorganization Plan"), the Company issued to holders of the Company's pre-Reorganization Plan common stock contingent value rights ("CVRs") to receive up to an aggregate of 2,665,000 shares (the "CVR Shares") of the Company's common stock. In connection with the issuance of the CVRs, the Company entered into a Contingent Value Rights Distribution Agreement (the "CVR Agreement"), in favor of holders of CVRs thereunder, dated as of July 1, 2009. Due to the nature of the CVRs, the Company accounted for the instrument in accordance with ASC No. 815, "Derivatives and Hedging," as well as related interpretations of this standard. The Company determined the CVRs to be derivative instruments to be accounted for as liabilities and marked to fair value at each balance sheet date. Upon issuance, the Company estimated the fair value of its CVRs using a Black-Scholes pricing model and consequently recorded a liability of $2.6 million in the balance sheet caption "other liabilities" as part of fresh-start accounting. Post-issuance change in value is reflected in the consolidated statements of operations as gain (loss) from contingent value rights valuation. The Company's estimates of fair value of its CVRs are correlated to and reflective of the Company's common stock price trends; in general, as the value of the Company's common stock increases, the estimated fair value of the CVRs also increases and, as a result, the Company recognizes a change in value of its CVRs as loss from contingent value rights valuation. Conversely and also in general, as the value of the Company's common stock decreases, the estimated fair value of the CVRs also decreases and as a result the Company would recognize a change in value of the CVRs as gain from contingent value rights valuation. See Note 10—"Fair Value of Financial Instruments and Derivatives". Stock-Based Compensation—The Company accounts for stock-based compensation under ASC No. 718, "Stock Compensation" (former SFAS No. 123(R), "Share-Based Payments"), which addresses the accounting for stock-based payment transactions whereby an entity receives employee services in exchange for equity instruments, including stock options and restricted stock units. ASC No. 718 generally requires that stock-based compensation be accounted for using a fair-value based method. The Company records stock-based compensation expense for all new and unvested stock options that are ultimately expected to vest as the requisite service is rendered. The Company issues new shares of common stock upon the exercise of stock options. The Company elected to adopt the alternative transition method for calculating the tax effects of share-based compensation. The alternative transition method includes simplified methods to determine the beginning balance of the additional paid in capital ("APIC") pool related to the tax effects of share-based compensation and to determine the subsequent impact on the APIC pool and the statement of cash flows of the tax effects of share-based award that were fully vested and outstanding upon the adoption of ASC No. 718. The Company uses a Black-Scholes option valuation model to determine the fair value of stock-based compensation under ASC No. 718. The Black-Scholes model incorporates various assumptions including the expected term of awards, volatility of stock price, risk-free rates of return and dividend yield. The expected term of an award is no less than the option vesting period and is based on the Company's historical experience. Expected volatility is based upon the historical volatility of the Company's stock price. The risk-free interest rate is approximated using rates available on U.S. Treasury securities with a remaining term similar to the option's expected life. The Company uses a dividend yield of zero in the Black-Scholes option valuation model as it does not anticipate paying cash dividends in the foreseeable future. Stock-based compensation is recorded net of expected forfeitures. Use of Estimates—The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of net revenue and expenses during the reporting period. Actual results may differ from these estimates. Significant estimates include allowance for doubtful accounts receivable, accrued interconnection cost disputes, the fair value of derivatives, market assumptions used in estimating the fair values of certain assets and liabilities, the calculation used in determining the fair value of the Company's stock options required by ASC No. 718, "Stock Compensation", income taxes and various tax contingencies. Estimates of fair value represent the Company's best estimates developed with the assistance of independent appraisals or various valuation techniques including Black-Scholes and, where the foregoing have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially. Any adjustments to the recorded fair values of these assets and liabilities, as related to business combinations, may impact the amount of recorded goodwill. Concentration of Credit Risk—Financial instruments that potentially subject the Company to concentration of credit risk principally consist of trade accounts receivable. The Company performs ongoing credit evaluations of its larger carrier and retail business customers but generally does not require collateral to support customer receivables. The Company maintains its cash with high quality credit institutions, and its cash equivalents are in high quality securities. Income (Loss) Per Common Share—Basic income (loss) per common share is computed using the weighted average number of shares of common stock outstanding during the year. Diluted income (loss) per common share is computed using the weighted average number of shares of common stock, adjusted for the dilutive effect of potential common stock and related income. Potential common stock, computed using the treasury stock method or the if-converted method, includes options, restricted stock units, warrants and convertible debt securities. Reclassification—Certain previous year amounts have been reclassified to conform with current year presentations, as related to the reporting of the Company's discontinued operations. Newly Adopted Accounting Principles In October 2009, an update was issued to the Revenue Recognition Topic, ASC 605, ASU 2009-13, "Revenue Recognition—Multiple-Deliverable Revenue Arrangements, a consensus of the FASB Emerging Issues Task Force." The update requires the establishment of a selling price hierarchy for determining the selling price of a deliverable. The hierarchy is: vendor specific objective evidence if available, third party evidence if vendor-specific objective evidence is not available or estimated selling price if neither of the aforementioned is available. The residual method of revenue allocation is no longer permissible. On January 1, 2011 the Company adopted this update, which did not have a material impact on the consolidated financial statements. In January 2010, an update was issued to the Fair Value Measurements and Disclosures Topic, ASC 820, ASU 2010-06, "Improving Disclosures about Fair Value Measurements," which requires new disclosures for fair value measurements and provides clarification for existing disclosures requirements. More specifically, this update requires (a) an entity to disclose separately the amounts of significant transfers in and out of Levels 1 and 2 fair value measurements and to describe the reasons for the transfers; and (b) information about purchases, sales, issuances and settlements to be presented separately (i.e., present the activity on a gross basis rather than net) in the reconciliation for fair value measurements using significant unobservable inputs (Level 3 inputs). This update clarifies existing disclosure requirements for the level of disaggregation used for classes of assets and liabilities measured at fair value and requires disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements using Level 2 and Level 3 inputs. This update was effective for the Company on January 1, 2010, except for Level 3 reconciliation disclosures which went into effect on January 1, 2011. The adoption of this update did not have a material impact on the consolidated financial statements. In December 2010, an update was issued to the Intangibles—Goodwill and Other Topic, ASC 350, ASU 2010-28, "When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts," which provides guidance for all entities that have recognized goodwill and have one or more reporting units whose carrying amount for purposes of performing Step 1 of the goodwill impairment test is zero or negative. The update modifies Step 1 so that for those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance, which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. On January 1, 2011 the Company adopted this update, which did not have a material impact on the consolidated financial statements. In December 2010, an update was issued to the Business Combinations Topic, ASC 805, ASU 2010-29, "Business Combinations—Disclosure of Supplementary Pro-Forma Information for Business Combinations", a consensus of the FASB Emerging Issues Task Force. These changes clarify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination, that occurred during the current year, had occurred as of the beginning of the comparable prior annual reporting period only. For the Company, this would be as of January 1, 2010. See Note 5—"Acquisitions." Also, the existing supplemental pro forma disclosures were expanded to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings, if any. On February 28, 2011, the Company adopted this update, and the required disclosures related to Arbinet are included in Note 5. In April 2011, an update was issued to the Receivables Topic, ASC 310, ASU 2011-02, "A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring," which provides guidance to all creditors, both public and nonpublic, that restructure receivables that fall within the scope of Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors. In evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude that both of the following exist: (1) the restructuring constitutes a concession and (2) the debtor is experiencing financial difficulties. The amendments to Topic 310 clarify the guidance on a creditor's evaluation of whether it has granted a concession and whether a debtor is experiencing financial difficulties. On July 1, 2011, the Company adopted this update, which did not have a material impact on the consolidated financial statements. New Accounting Pronouncements In May 2011, an update was issued to the Fair Value Measurement Topic ASC 820, ASU 2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs," which provides guidance on how to measure fair value and on what disclosures to provide about fair value measurements. It seeks to develop a single, converged fair value framework between the FASB and International Financial Reporting Standards ("IFRS") Board. The Company's effective date for adoption is January 1, 2012 and it does not foresee this accounting update having a material effect on its consolidated financials in future periods, although that could change. In June 2011, an update was issued to the Comprehensive Income Topic ASC 220, ASU 2011-05, "Presentation of Comprehensive Income," which provides guidance to all entities that report items of other comprehensive income, in any period presented. Under the amendments in this update, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. In a single continuous statement, the entity is required to present the components of net income and total net income, the components of other comprehensive income and a total for other comprehensive income, along with the total of comprehensive income in that statement. In the two-statement approach, an entity is required to present components of net income and total net income in the statement of net income. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive income. ASU 2011-05 also contains a provision that requires the entity to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. In December 2011, an update was issued to the Comprehensive Income Topic ASC 220, ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05," which indefinitely deferred the requirement to present the reclassification adjustments out of other comprehensive income. The Company's effective date for adoption is January 1, 2012 and it does not foresee this accounting update having a material effect on its consolidated financials in future periods, although that could change. In September 2011, an update was issued to the Intangibles—Goodwill and Other Topic ASC 350, ASU 2011-08, "Testing Goodwill for Impairment," which provides guidance to all entities, both public and nonpublic, that have goodwill reported in their financial statements. Under the amendments in this update, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss. An entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The Company's effective date for adoption is January 1, 2012 and it does not foresee this accounting update having a material effect on its consolidated financials in future periods, although that could change. In December 2011, an update was issued to the Balance Sheet Topic ASC 210, ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities," which contains new disclosure requirements regarding the nature of an entity's right of setoff and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under IFRSs. Generally, it is more difficult to qualify for offsetting under IFRSs than it is under U.S. GAAP because under U.S. GAAP certain derivative and repurchase agreement arrangements are granted exceptions from the general offsetting model. As a result, entities with significant financial instrument and derivative portfolios that report under IFRSs typically present positions on their balance sheets that are significantly larger than those of entities with similarly sized portfolios whose financial statements are prepared in accordance with U.S. GAAP. To facilitate comparison between financial statements prepared under U.S. GAAP and IFRSs, the new disclosures will give financial statement users information about both gross and net exposures. The Company's effective date for adoption is January 1, 2014 and it does not foresee this accounting update having a material effect on its consolidated financials in future periods, although that could change.

Fresh-Start Accounting [Abstract]

Fresh-Start Accounting

4. FRESH-START ACCOUNTING

On July 1, 2009, the Company adopted fresh-start accounting in accordance with ASC No. 852, "Reorganizations." Fresh-start accounting results in the Company becoming a new entity for financial reporting purposes. Accordingly, the Successor Company's consolidated financial statements are not comparable to consolidated financial statements of the Predecessor Company.

Under ASC No. 852, the Successor Company must determine a value to be assigned to the equity of the emerging company as of the date of adoption of fresh-start accounting. To facilitate this calculation the Company first determined the enterprise value of the Successor Company. The valuation methods included (i) a discounted cash flow analysis, considering a range of the weighted average cost of capital between 14.0% and 16.0% and multiples of projected earnings of between 4.5 and 5.0 times for its terminal value, and (ii) a market multiples analysis. This analysis resulted in an estimated enterprise value of between $320 million and $360 million, and with the midpoint of $340 million chosen for purposes of applying fresh-start accounting.

The estimated enterprise value, and corresponding equity value, is highly dependent upon achieving the future financial results set forth in the financial projections included in the Company's Plan, as filed with the Bankruptcy Court. These projections were limited by the information available to the Company as of the date of the preparation of the projections and reflected numerous assumptions concerning anticipated future performance and prevailing and anticipated market and economic conditions that were and continue to be beyond the Company's control and that may not materialize. Projections are inherently subject to uncertainties and to a wide variety of significant business, economic and competitive risks. Therefore variations from the projections may be material.

Fresh-start accounting reflects the value of the Company as determined in the confirmed Plan. Under fresh-start accounting, the Company's asset values are remeasured and allocated in conformity with ASC No. 805, "Business Combinations." The excess of reorganization value over the fair value of tangible and identifiable intangible assets is recorded as goodwill in the accompanying consolidated balance sheet. Fresh-start accounting also requires that all liabilities, other than deferred taxes and pension and other postretirement benefit obligations, should be stated at fair value.

Estimates of fair value included in the Successor Company financial statements, in conformity with ASC No. 820, represent the Company's best estimates and valuations developed with the assistance of independent appraisers and, where the foregoing have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The foregoing estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially. In accordance with ASC No. 805, the allocation of the reorganization value is subject to additional adjustment until the Company has completed its analysis, but not to exceed one year after emergence from bankruptcy, to provide the Company with the time to complete the valuation of its assets and liabilities. The Company finalized the determination of the fair value of individual assets and liabilities during the first six months of 2010.

The following fresh-start consolidated condensed balance sheet presents the financial effects on the Company of the implementation of the Plan and the adoption of fresh-start accounting. The effect of the consummation of the transactions contemplated in the Plan includes the settlement of liabilities and the issuance of common stock as described in more detail in Note 2—"Emergence from Voluntary Reorganization Under Chapter 11 of the Bankruptcy Code."

The effects of the Plan and fresh-start reporting on the Company's consolidated balance sheet are as follows:

Notes to Plan of Reorganization and fresh-start accounting adjustments:

(a)

This adjustment reflects the discharge of $451.1 million of liabilities subject to compromise (see "Liabilities Subject to Compromise" above), which includes $123.5 million Senior Subordinated Secured Notes reclassed to long-term obligations, in accordance with the terms of the Plan and the issuance of 4.8 million shares of Successor Company common stock to the holders of each of the Senior Subordinated Secured Notes and the Holding Senior Notes.

(b)

To record the issuance of Contingent Value Rights to the holders of the Old Common Stock.

(c)

To record the cancellation of the Old Common Stock.

(d)

To record assets and liabilities at their estimated fair values per fresh-start accounting. These amounts include adjustments to the estimated fair values from what was originally reported in the quarter ending September 30, 2009.

(e)

To reclass Term Loan from current portion of long-term obligations to long-term obligations and record the issuance of the Senior Subordinated Secured Notes.

(f)

To reset additional paid-in capital, accumulated other comprehensive loss and accumulated deficit to zero.

(g)

To reclass long-term portion of the Term Loan to long-term obligations.

(h)

To record the deferred tax attributes related to fresh-start accounting.

In the fourth quarter of 2009, the Company further adjusted the fair value of certain assets and liabilities to reflect the excess of the reorganization value of the Successor over the fair values of tangible and identifiable intangible assets, net of liabilities, from the adoption of fresh-start reporting. Property, plant and equipment, net and Other intangibles, net, were reduced by $1.9 million and $3.2 million, respectively; Goodwill and Other assets increased by $1.9 million and $1.3 million, respectively; and Accrued expenses and other current liabilities and Other liabilities were reduced by $1.8 million and $0.1 million, respectively.

5. ACQUISITIONS

Arbinet Corporation Acquisition

On February 28, 2011, the Company completed its previously announced acquisition of Arbinet Corporation, a Delaware corporation ("Arbinet"). Arbinet is a provider of wholesale telecom exchange services to carriers and the Company purchased Arbinet to supplement its existing International Carrier Services operations. Pursuant to the terms of the Agreement and Plan of Merger dated as of November 10, 2010, as amended by Amendment No. 1 dated December 14, 2010, by and among Primus, PTG Investments, Inc., a Delaware corporation and a wholly-owned subsidiary of Primus ("Merger Sub"), and Arbinet, Merger Sub merged with and into Arbinet with Arbinet surviving the merger as a wholly-owned subsidiary of Primus.

Upon the closing of the merger, each share of Arbinet common stock was cancelled and converted into the right to receive 0.5817 shares of Primus common stock. Arbinet stockholders received cash in lieu of any fractional shares of Primus common stock that they were otherwise entitled to receive in the merger. In connection with the merger, Primus issued 3,232,812 shares of its common stock to former Arbinet stockholders in exchange for their shares of Arbinet common stock, and reserved for issuance approximately 95,000 additional shares of its common stock in connection with its assumption of Arbinet's outstanding options, warrants, stock appreciation rights and restricted stock units.

The components of the consideration transferred follow (in thousands):


Consideration attributable to stock issued (1)	$	50,432
Consideration attributable to earned replaced equity awards (2)		177

Total consideration transferred	$	50,609

(1)	The fair value of the Company's common stock on the acquisition date was $15.60 per share based on the closing value of its common stock traded on the over-the-counter bulletin board. The Company issued 3,232,812 shares of stock to effect this merger.

(2)

The portion of the acquisition fair value of Arbinet converted stock-based awards attributable to pre-merger employee service was part of consideration. At the merger closing 50% of the unvested and outstanding Arbinet awards vested. The portion of the fair value-based measure of the replaced awards assigned to past services (including those for which vesting accelerated at the merger closing and those that were already vested at the date of the merger closing) was included in the consideration transferred.

On February 11, 2011, prior to the Company's acquisition of Arbinet, Arbinet entered into a definitive asset purchase agreement (the "Asset Purchase Agreement") with AIP Acquisition LLC, a Delaware limited liability company ("Buyer"), pursuant to which Buyer agreed to acquire from Arbinet and certain of its wholly owned subsidiaries, a portfolio of patents and patent applications and the rights arising from such patents and patent applications (the "Patent Portfolio") for an aggregate cash consideration equal to $4,000,000 and to assume all liabilities associated with the Patent Portfolio. Pursuant to the terms of the Asset Purchase Agreement, the Patent Portfolio is being sold on an "as is," "where is" basis. The closing of the sale of the Patent Portfolio pursuant to the Asset Purchase Agreement occurred on February 16, 2011. In connection with the signing of the Asset Purchase Agreement, Arbinet and Buyer also entered into a license agreement (the "License Agreement") that became effective on February 16, 2011, pursuant to which Buyer granted-back to Arbinet a royalty-free, worldwide, assignable (on a non-exclusive basis) and perpetual license and right to use the Patent Portfolio. The Singer Children's Management Trust, which owned approximately 23.1% of Arbinet's outstanding common stock and approximately 9.5% of the outstanding common stock of Primus Telecommunications Group, Incorporated, as of January 7, 2011, is the sole member of the Buyer.

Preliminary Recording of Assets Acquired and Liabilities Assumed

The transaction was accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date.

Estimates of fair value included in the financial statements, in conformity with ASC No. 820, "Fair Value Measurements and Disclosures" ("ASC 820"), represent the Company's best estimates and valuations developed with the assistance of independent appraisers and, where the following have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The following estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially. In accordance with ASC No. 805, "Business Combinations" ("ASC 805"), the allocation of the consideration value is subject to additional adjustment until the Company has completed its analysis. The Company's analysis and any additional adjustments are required to be made by February 28, 2012, the one year anniversary of the date of the acquisition, to provide the Company with the time to complete the valuation of its assets and liabilities.

The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed (in thousands):


Cash and cash equivalents	$	12,415
Marketable securities		4,044
Accounts receivable		16,205
Other current assets		884
Property and equipment ⁽¹⁾		17,297
Intercompany receivable		309
Goodwill ⁽²⁾		21,865
Customer list ⁽³⁾		900
Exchange license ⁽³⁾		2,800
Other intangible assets ⁽³⁾		700
Other assets		1,738

Total assets acquired	$	79,157

Trade payables	$	18,280
Accrued interconnection costs		105
Accrued liabilities		3,146
Other current liabilities		3,182
Current portion of long-term obligations		68
Long-term obligations		99
Other long-term liabilities		3,668

Total liabilities assumed	$	28,548

Net assets acquired	$	50,609

(1)

Property and equipment were measured primarily using an income approach. The fair value measurements of the assets were based, in part, on significant inputs not observable in the market and thus represent a Level 3 measurement. The significant inputs included Arbinet resources, assumed future revenue profiles, weighted average cost of capital of 13.0%, gross margin of 7.2% and assumptions on the timing and amount of future development and operating costs. The property and equipment additions were segmented as part of a new stand-alone reporting unit which will be aggregated with International Carrier Services when integration activities are substantially complete.

(2)

Goodwill was the excess of the consideration transferred over the net assets recognized and represents the future economic benefits, primarily as a result of expected synergies expected from the combination, arising from other assets acquired that could not be individually identified and separately recognized. Goodwill was recognized as part of a new stand-alone reporting unit which will be aggregated with International Carrier Services when integration activities are substantially complete. Goodwill is not amortized and is not deductible for tax purposes.

(3)	Identifiable intangible assets and other assets were measured using a combination of an income approach and a market approach (Level 3). Identifiable intangible assets are subject to amortization and the customer list and exchange license will be amortized over 15 years and 10 years, respectively.

Arbinet Results and Pro Forma Impact of Merger

The following table presents revenues for Arbinet for the periods presented (in thousands):


	Year Ended December 31, 2011		Acquisition Date through December 31, 2011
Net revenue	$	263,930	$	211,023

The Company incurred a total of $2.0 million in transaction costs related to the merger. Transaction-related costs were expensed as incurred except for $1.1 million of costs incurred to issue common stock to effect the merger which were recorded as an offset to additional paid in capital. The transaction-related costs recognized in the line item "Selling, general, and administrative expenses" in the consolidated statement of operations during the years ended December 31, 2011 and 2010 were $0.2 million and $0.7 million, respectively. The fair value of the total consideration paid for the assets acquired and liabilities assumed increased significantly from the date of the merger agreement, November 10, 2010, to the closing date February 28, 2011. This event triggered the Company to perform a Step 1 impairment test as related to the goodwill which arose from this acquisition. See Note 7—"Goodwill and Other Intangible Assets" for more details on the testing. The results of the Step 1 and Step 2 tests required the Company to recognize $14.7 million of impairment expense during the three months ended March 31, 2011. The following table presents pro forma information for the Company as if the merger of Arbinet had occurred at the beginning of each period presented (in thousands, except for per share amounts):


	Successor
	Year Ended December 31, 2011			Year Ended December 31, 2010
Net revenue	$	1,041,291		$	1,067,489
Net income (loss) attributable to continuing operations for Primus		(32,267	)		(28,231	)
Net income (loss) attributable to discontinued operations for Primus		(5,200	)		(7,875	)
Income (loss) per common share for continuing operations net of tax	$	(2.39	)	$	(2.18	)
Income (loss) per common share for discontinued operations		(0.38	)		(0.61	)

The historical financial information was adjusted to give effect to the pro forma events that were directly attributable to the merger and factually supportable. The unaudited pro forma consolidated results are not necessarily indicative of what the consolidated results of operations actually would have been had the Company completed the merger on January 1, 2011 or January 1, 2010. In addition, the unaudited pro forma consolidated results do not purport to project the future results of operations of the combined company.

Incentive Program

Under the terms of the merger agreement, outstanding Arbinet stock-based awards were converted into Primus stock-based awards based on the merger exchange ratio. The converted Arbinet awards, granted under Arbinet's 1997 and 2004 Stock Incentive Plans, include restricted stock awards, stock options, stock appreciation rights and restricted stock units. The grant date for the converted Arbinet awards is considered to be the closing date of the merger for purposes of calculating fair value. The maximum term of the Arbinet awards is ten years. No additional awards will be issued under either Arbinet plan.

Unlimitel Inc. and HMNET Technologies, Inc. Acquisitions

During the first quarter of 2011 one of the Company's Canadian subsidiaries completed the acquisitions of the customer base and fixed assets of Unlimitel Inc. ("Unlimitel") and HMNet Technologies Inc. ("HMNet"), both commercial VoIP providers. The total consideration transferred to complete the acquisitions was approximately $3.1 million. The cash payments associated with the acquisitions are as follows: $1.0 million was paid upon closing, $0.3 million was paid during the second quarter of 2011, $1.4 million is payable upon the one-year anniversary of the closing date, and $0.4 million is payable upon the two-year anniversary of the closing date.

The table below sets forth the final Unlimitel and HMNet purchase price allocation (in thousands). The purchase price allocation resulted in goodwill of $1.8 million. The valuation of intangible assets was evaluated using Level 3 inputs.


	As of December 31, 2011
Cash and cash equivalents	$	331
Property and equipment		136
Identifiable intangible asset:
Customer relationships		1,229
Goodwill		1,842
Other assets and liabilities, net		(119	)
Deferred income tax		(318	)

Allocation of purchase consideration	$	3,101

The customer relationships above are subject to amortization and have a useful life of five years. The useful life of the customer relationships was estimated at the time of the acquisition based on the period of time from which the Company expects to derive benefits from the customer relationships. The identifiable intangible assets are amortized using the pattern of benefits method, which results in accelerated amortization in the early periods of the useful life.

Goodwill from the Company's Unlimitel and HMNet acquisitions was the excess of the consideration transferred over the net assets recognized, which represents the value of acquired employees along with the expected synergies from the combination of Unlimitel Inc. and HMNet Technologies Inc. and the Company's operations. Goodwill resulting from the acquisition of Unlimitel Inc. and HMNet Technologies Inc. is not deductible for tax purposes.

Hyperlink Australia Pty Ltd. Acquisition

During the first quarter of 2011 one of the Company's Australian subsidiaries completed the acquisition of the customer relationships and fixed assets of Hyperlink Australia Pty Ltd. ("Hyperlink"), a managed data center services provider. The total consideration transferred to complete the acquisition of Hyperlink totaled $1.5 million which included cash paid of $0.8 million and routine working capital adjustments of $0.7 million.

The table below sets forth the final Hyperlink purchase price allocation (in thousands). The fair value of the property and equipment were determined based on Level 3 inputs. The valuation of intangible assets was evaluated using Level 3 inputs.


	As of December 31, 2011
Property and equipment	$	128
Identifiable intangible asset:
Customer relationships		1,467
Other assets and liabilities, net		(69	)

Allocation of purchase consideration	$	1,526

The customer relationships above are subject to amortization and have a useful life of three years. The useful life of the customer relationships was estimated at the time of the acquisition based on the period of time from which the Company expects to derive benefits from the customer relationships. The identifiable intangible assets are amortized using the pattern of benefits method, which results in accelerated amortization in the early periods of the useful life.

Goodwill And Other Intangible Assets [Abstract]

Goodwill And Other Intangible Assets

7. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill reflects the excess of the reorganization value of Successor over the fair value of tangible and identifiable intangible assets as determined upon the adoption of fresh-start accounting. The Company recorded goodwill of $61.3 million upon emergence from bankruptcy as well as intangible assets of $184.8 million, which includes $81.6 million of indefinite-lived trade names, $99.2 million of amortizable customer relationships, and $4.0 million of amortizable trade names.

Generally accepted accounting principles in the United States require the Company to perform a goodwill impairment test, a two-step test, annually and more frequently when negative conditions or a triggering event arise. The Company completes its annual goodwill impairment test using October 1 as the measurement date for each of its reporting units.

In step one, the estimated fair value of each reporting unit is compared to its carrying value. The Company estimates the fair values of each reporting unit by a combination of (i) estimation of the discounted cash flows of each of the reporting units based on projected earnings in the future (the income approach) and (ii) a comparative analysis of revenue and EBITDA multiples of public companies in similar markets (the market approach). If there is a deficiency (the estimated fair value of a reporting unit is less than its carrying value), a step two test is required. In step two, the amount of any goodwill impairment is measured by comparing the implied fair value of the reporting unit's goodwill to the carrying value of goodwill, with the resulting impairment reflected in operations. The implied fair value is determined in the same manner as the amount of goodwill recognized in a business combination.

Estimating the fair value of a reporting unit requires various assumptions including projections of future cash flows, perpetual growth rates and discount rates. The assumptions about future cash flows and growth rates are based on management's assessment of a number of factors including the reporting unit's recent performance against budget, performance in the market that the reporting unit serves, as well as industry and general economic data from third party sources. Discount rate assumptions are based on an assessment of the risk inherent in those future cash flows. Changes to the underlying businesses could affect the future cash flows, which in turn could affect the fair value of the reporting unit.

As of the most recent annual test conducted on October 1, 2011, the Company concluded that the fair value of each of the reporting units exceeded its carrying value of invested capital and therefore, no potential goodwill impairment existed. For one of the reporting units for which the goodwill balance was $37 million as of December 31, 2011, the fair value exceeded the carrying value by approximately 6%. The Company performed a sensitivity test at October 1, 2011 that showed a 100 basis point increase and decrease in its discount rate or a 50 basis point increase and decrease in the terminal growth rate for each reporting unit and concluded that no potential goodwill impairment existed at October 1, 2011.

During the three months ended September 30, 2010, the Company and its Board of Directors ratified a plan to proceed with the disposition of its European retail operations; see Note 20, Discontinued Operations. This triggering event prompted the Company to perform a goodwill impairment test, a two-step test, for the Europe reporting unit. Based on the results of the step one test, the Company determined that the carrying value of the Europe reporting unit was in excess of its respective fair value and a step two test was required for the reporting unit.

In completing the step two test to determine the implied fair value of goodwill and therefore the amount of impairment, management first estimated the fair value of the tangible and intangible assets and liabilities. Based on the testing performed, the Company determined that the carrying value of goodwill exceeded its implied fair value for the Europe reporting unit and recorded a goodwill impairment charge of $1.4 million. The impairment charge is included in the line item "Loss from discontinued operations, net of tax," on the Company's consolidated statement of operations.

The primary driver for the decline in the estimated fair value of the Europe reporting unit compared to the prior year is the decline in its overall outlook stemming from its poor performance.

In addition, the Company evaluated the European trade name and long-lived assets, which primarily consisted of the network equipment and customer relationships, for impairment. In performing the impairment test for the European trade name and long-lived assets, the Company estimated the fair value less cost to sell for the asset groups based on executed and pending purchase offers and compared that to the carrying value of the asset groups. The company recorded a total of $4.7 million impairment charges; $4.2 million related to the European trade name, $0.4 million related to customer relationships and $0.1 million related to long-lived assets during the three months ended September 30, 2010. The impairment charge is included in the line item "loss from discontinued Operations, net of tax," on the Company's consolidated statement of operations.

On February 28, 2011 the Company acquired Arbinet for stock consideration of $50.6 million in a stock for stock transaction. See Note 5—"Acquisitions." Because the Company's stock price rose significantly between the signing of the merger agreement on November 10, 2010 and the close of the merger on February 28, 2011 from a closing price of $9.57 per share to $15.60 per share, the fixed-share consideration fair value also rose. Because Arbinet's enterprise value may not have increased within similar levels over that time period, the Company determined that a goodwill impairment assessment was immediately necessary post-merger. On the day of the merger, Arbinet was a stand-alone business with its own cash flows and management structure, and the Company evaluated it as a separate reporting unit. The Company determined the preliminary enterprise value of Arbinet to be $36.2 million, which was less than the carrying value of $50.6 million. For Step 2 of the testing, the fair value of the assets acquired and liabilities assumed was deemed to be equal to that which was used for the purchase price allocation. Based on an enterprise value of $36.2 million and the fair value of the assets acquired and liabilities assumed at purchase, the company calculated $4.7 million of implied goodwill. Because the carrying value of goodwill was greater than the implied goodwill, $14.7 million was recorded as "Goodwill impairment" on the Company's consolidated statements of operations. Post acquisition, Arbinet was integrated into the Company's International Carrier Services ("ICS") segment, see Note 16 "Operating Segment and Related Information."

Exchange Offers

On July 7, 2011, in connection with the consummation of the private (i) exchange offers (the "Exchange Offers") for any and all outstanding Units representing the 13% Senior Secured Notes due 2016 (the "13% Notes") issued by Primus Telecommunications Holding Inc. ("Holding") and Primus Telecommunications Canada Inc. ("Primus Canada"), and the 14 ¹/4% Senior Subordinated Secured Notes due 2013 (the "14 ¹/4% Notes") issued by Primus Telecommunications IHC, Inc. ("IHC"), (ii) consent solicitation (the "Consent Solicitation") to amend the indenture governing the 13% Notes and release the collateral securing the 13% Notes, and (iii) related transactions, Holding issued $240.2 million aggregate principal amount of 10% Senior Secured Notes due 2017 (the "10% Notes"). An aggregate of $228.6 million principal amount of 10% Notes was issued pursuant to the Exchange Offers, and Holding issued an additional $11.6 million aggregate principal amount of 10% Notes for cash, the proceeds of which were used to redeem all 14¹/4% Notes that were not exchanged pursuant to the Exchange Offers and thereby discharge all of the Company's obligations with respect to the 14¹/4% Notes. In connection with the Exchange Offers, the Company also incurred $6.9 million of third party costs which are included in gain (loss) on early extinguishment or restructuring of debt on the consolidated statement of operations.

10% Senior Secured Notes due 2017

As of December 31, 2011, there was $235.2 million principal amount of the 10% Notes outstanding. The 10% Notes bear interest at a rate of 10.00% per annum, payable semi-annually in arrears in cash on April 15 and October 15 of each year, commencing October 15, 2011. The 10% Notes will mature on April 15, 2017. In December 2011, the Company repurchased $5.0 million in aggregate principal amount of the 10% Notes at 99% of face value.

The 10% Notes are governed by an indenture, dated as of July 7, 2011 (the "10% Notes Indenture"), by and among Holding, the guarantors of the 10% Notes named therein, including Group (the "Guarantors"), and U.S. Bank National Association, as trustee and collateral trustee. The 10% Notes and related guarantees are secured by a pledge of and first lien security interest in (subject to certain exceptions) substantially all of the assets of Holding and the Guarantors, including a first-priority pledge of all of the capital stock held by Holding, the Guarantors and each subsidiary of Group that is a foreign subsidiary holding company (which pledge, in the case of the capital stock of each non-U.S. subsidiary and each subsidiary of Group that is a foreign subsidiary holding company is limited to 65% of the capital stock of such subsidiary).

The 10% Notes rank senior in right of payment to existing and future subordinated indebtedness of Holding and the Guarantors. The 10% Notes rank equal in right of payment with all existing and future senior indebtedness of Holding and the Guarantors. The 10% Notes rank junior to any priority lien obligations entered into by Holding or the Guarantors in accordance with the 10% Notes Indenture.

Prior to March 15, 2013, Holding may redeem up to 35% of the aggregate principal amount of the 10% Notes at the redemption premium of 110% of the principal amount of the 10% Notes redeemed, plus accrued and unpaid interest, with the net cash proceeds of certain equity offerings. Prior to March 15, 2013, Holding may redeem some or all of the 10% Notes at a make-whole premium as set forth in the 10% Notes Indenture. On or after March 15, 2013, Holding may redeem some or all of the 10% Notes at a premium that will decrease over time as set forth in the 10% Notes Indenture, plus accrued and unpaid interest.

Upon the occurrence of certain Changes of Control (as defined in the 10% Notes Indenture) with respect to the Company, Holding must give holders of the 10% Notes an opportunity to sell their 10% Notes to Holding at a purchase price of 101% of the principal amount of such 10% Notes, plus accrued and unpaid interest, if any, to the date of purchase. If Group or any of its restricted subsidiaries sells certain assets and does not use all of the net proceeds of such sale for specified purposes, Holding may be required to use the remaining net proceeds from such sale to offer to repurchase some of the 10% Notes at 100% of their principal amount, plus accrued and unpaid interest.

The 10% Notes Indenture contains covenants that, subject to certain exceptions, limit the ability of each of Group and its restricted subsidiaries to, among other things: (i) incur additional indebtedness; (ii) pay dividends on, repurchase or make distributions in respect of the Group's capital stock or make other restricted payments; (iii) make certain investments; (iv) sell, transfer or otherwise convey certain assets; (v) create certain liens; (vi) designate future subsidiaries as unrestricted subsidiaries; (vii) consolidate, merge, sell or otherwise dispose of all or substantially all of its assets; and (viii) enter into certain transactions with affiliates. The 10% Notes Indenture contains other customary terms, including, but not limited to, events of default, which, if any of them occurs, would permit or require the principal, premium, if any, and interest, if any, on all of the then outstanding 10% Notes to be due and payable immediately.

Under the 10% Notes Indenture, either Holding or any Guarantor may incur additional senior secured debt, equal in right of payment to the 10% Notes, in the future that is subject to security interests in the same collateral as the 10% Notes and the related guarantees, in an aggregate principal amount outstanding (including the aggregate principal amount outstanding under the 10% Notes) equal to 2.25 times consolidated EBITDA Group for the prior four fiscal quarters. Holding has no obligation or intention to register the 10% Notes for resale under the Securities Act or the securities laws of any other jurisdiction or to offer to exchange the 10% Notes for securities registered under the Securities Act or the securities laws of any other jurisdiction.

13% Senior Secured Notes due 2016

As of December 31, 2011, there was $2.4 million principal amount of the 13% Notes outstanding. The 13% Notes bear interest at a rate of 13.00% per annum, payable semi-annually in arrears in cash on June 15 and December 15 of each year. The 13% Notes will mature on December 16, 2016.

On April 19, 2011, Holding and Primus Canada commenced an offer to purchase (the "Offer to Purchase") up to 5,200 Units, each such Unit consisting of $1,000 principal amount of 13% Notes issued by Holding and Primus Canada, at a purchase price in cash equal to 100% of the principal amount of 13% Notes validly tendered (and not validly withdrawn) prior to the expiration time, plus accrued but unpaid interest thereon to the settlement date for the Offer to Purchase. The Offer to Purchase was made pursuant to the excess cash flow covenant in the terms of the indenture governing the 13% Notes. The Offer to Purchase expired on May 17, 2011 and $32,000 principal amount of 13% Notes were tendered and repurchased pursuant to the Offer to Purchase.

Upon consummation of the Exchange Offers, $127.6 million principal amount of 13% Notes was exchanged for $149.3 million principal amount of 10% Notes. The Company evaluated the application of ASC 470-50, "Modifications and Extinguishments" and concluded that the Exchange Offers constituted a debt modification with respect to the 13% Notes. Under ASC 470-60, the prepayment premium of $21.7 million paid to the exchanging holders of 13% Notes, was capitalized and will be amortized over the life of the 10% Notes. It is included in other assets in the consolidated balance sheets. Following the completion of the Exchange Offers and Consent Solicitation, the indenture governing the 13% Notes has been amended to eliminate most restrictive covenants and certain events of default and to release the collateral securing the 13% Notes.

14¹/4% Senior Subordinated Secured Notes due 2013

On April 15, 2011, IHC redeemed approximately $24.0 million principal amount of 14¹/4% Notes. Accrued interest to, but excluding the redemption date, of approximately $1.3 million on the redeemed portion of the 14¹/4% Notes was also paid on the redemption date. There was $90.0 million principal amount of the 14¹/4% Notes remaining outstanding after this redemption.

Upon consummation of the Exchange Offers, $78.4 million principal of 14¹/4% Notes was exchanged for $79.4 million principal amount of 10% Notes. The Company evaluated the application of ASC 470-50, "Modifications and Extinguishments" and concluded that the Exchange Offers constituted a debt modification with respect to the 14¹/4% Notes. Under ASC 470-60, the prepayment premium of $1.0 million paid to the exchanging holders of 14¹/4% Notes, was capitalized and will be amortized over the life of the 10% Notes. It is included in other assets in the consolidated balance sheets. Holding issued an additional $11.6 million aggregate principal amount of 10% Notes for cash, the proceeds of which were used to redeem all 14¹/4% Notes that were not exchanged pursuant to the Exchange Offers and thereby discharge all of the Company's obligations with respect to the 14¹/4% Notes.

Deferred income taxes are recognized to account for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts of each period-end, based on enacted tax laws and statutory income tax rates applicable to periods in which the differences are expected to affect taxable income. Deferred income taxes reflect the net income tax effect of temporary differences between the basis of assets and liabilities for financial reporting purposes and for income tax purposes. Net deferred tax balances are comprised of the following as of December 31, 2011 and 2010 (in thousands):


	Successor
	As of December 31,
	2011			2010
Deferred tax assets	$	195,569		$	123,365

Deferred tax liabilities		(79,305	)		(58,152	)

Net deferred taxes	$	(28,347	)	$	(29,071	)

Certain fixed and intangible assets were marked to their fair market values, as a result of our emergence from bankruptcy and the associated fresh-start accounting (see Note 4—"Fresh-Start Accounting"), which resulted in a substantial decrease to our deferred tax asset, net operating loss carryforwards, the discharge of certain tax liabilities, and tax attribute reduction, as prescribed by Internal Revenue Code Section 108.

The significant components of the Company's deferred tax assets and liabilities are as follows as of December 31, 2011 and 2010 (in thousands):

As of December 31, 2011, the Company had foreign operating loss carryforwards of approximately $164 million of which $56.1 million expire periodically from 2012 through 2031, and the remainder of which carryforward without expiration.

At December 31, 2011, the Company projects United States operating loss carryforwards available to reduce future United States taxable income in the amount of $198.3 million, of which $143.6 million is subject to limitation under Section 382, and of which $54.7 million is not subject to the Section 382 limit. Net operating losses which survived attribute reduction as a result of fresh-start accounting will expire periodically between 2014 through 2031, are subject to limitations in accordance with Section 382 of the Internal Revenue Code.

Pursuant to Section 382 of the Internal Revenue Code, the Company believes that it underwent an ownership change for tax purposes (i.e., a more than 50% change in stock ownership) on the July 1, 2009 emergence date. As a result, the use of any of the Company's federal and state NOL carryforwards and tax credits generated prior to the ownership change (that are not reduced as a result of fresh-start accounting) will be subject to an annual limitation of approximately $1.6 million. The annual limitation was determined based upon an Internal Revenue Code section that allows corporations emerging from bankruptcy to determine their section 382 limitation based upon the post emergence stock value. The Company has prepared its financial statements assuming the annual limitation will apply.

As of February 28, 2011, and the completion of the merger of PTG Investments, a wholly-owned subsidiary of the Company with and into Arbinet Corporation, the Company believes that an ownership change for tax purposes took place with respect to both Primus and Arbinet. This conclusion is based on Schedule 13D and Schedule 13G filings concerning Company securities, as filed with the United States Securities and Exchange Commission. As a result of the ownership change an annual limitation of $7.0 million is required under section 382 of the Company's then-existing NOLs. This limitation is in addition to the NOL utilization limitation of approximately $1.6 million due to the July 1, 2009, ownership change. The annual limitation under section 382 of Arbinet then-existing NOLs is approximately $2.2 million.

The Company is required to determine whether it had a net unrealized built-in gain (NUBIG) or net unrealized built-in loss (NUBIL) at the 2009 emergence date. The Company estimated that there was a NUBIL at the time of the 2009 emergence date. As a result, certain depreciation and loss deductions recognized during the five-year period beginning on the 2009 emergence date were subject to the Section 382 limitation. A 2011 review of tax basis demonstrated that at the emergence date in 2009 the Company was in a NUBIG, as a result certain depreciation and loss deductions that were previously limited are available. The amount of the previously limited losses is $8.0 million.

As a result of the fresh-start accounting, the Company has increased its deferred tax liabilities and goodwill by $55.7 million to reflect the increase in book basis without any increase in the tax basis of certain assets which were adjusted for the fresh-start. $31.2 million of the deferred tax liabilities relates to the fresh-start increase in the value of certain indefinite lived intangibles. These deferred tax liabilities will remain on the books indefinitely subject to reduction only if the related indefinite lived intangibles which gave rise to the deferred tax liabilities are impaired. The reduction of the deferred tax liability due to impairment of the underlying indefinite lived intangibles would provide a tax benefit for the Company which would be offset by any future impairment expense of the indefinite lived intangibles. The remaining $24.5 million of deferred tax liability will be a tax benefit which will be offset when its underlying fresh-start adjustment is released. The relief of the deferred tax liability will not result in any payment of cash by the company.

The Company incurred $(1.0) million, $(0.9) million and $(2.8) million of expense in 2011, 2010 and 2009, respectively, related to foreign withholding tax on intercompany interest and royalties owed to our United States subsidiary.

On December 15, 2008 the U.S. Treasury Department announced that the Fifth Protocol ("Protocol") to the United States—Canada Income Tax Treaty entered into force. The Protocol is generally effective for tax years beginning on or after January 1, 2009, however certain provisions of the Protocol have different effective dates. The elimination of withholding tax on interest paid or credited between related parties is phased in over a 3-year period, between 2008 through 2010. The reduced withholding tax rates are 7% for 2008, 4% for 2009, and 0% for 2010 and thereafter. Effective January 1, 2010, interest paid by or to certain hybrid entities will not qualify for treaty benefits. The changes made by the Protocol have substantially reduced the accrued income tax.

During the fourth quarter of 2009, the company restructured its Canadian hybrid entity such that the Company now qualifies for an exemption from Canadian withholding tax on interest from Canadian subsidiaries. This restructuring also resulted in the release of accrued withholding tax resulting in a tax benefit of $2.8 million during 2009.

No provision was made in 2011 for United States income taxes on the undistributed earnings of the foreign subsidiaries as it is the Company's intention to utilize those earnings in the foreign operations for an indefinite period of time.

The Company follows the provision of ASC No. 740-10, "Income Taxes" which prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the Company has taken or expects to take on a tax return. The Company is subject to challenge from various taxing authorities relative to certain tax planning strategies, including certain intercompany transactions as well as regulatory taxes.

Reconciliations of the successor period July 2, 2009 to December 31, 2009, January 1, 2010 to December 31, 2010, and January 1, 2011 to December 31, 2011 and predecessor periods of January 1, 2009 to July 1, 2009 balances of unrecognized tax benefits are as follows (in thousands):

Balance at December 31, (July 1, for 2009 Predecessor period)	$	86,206		$	88,299		$	89,716		$	88,953

The total unrecognized tax benefits as of December 31 2011 were $86.2 million. Total unrecognized tax benefits of $5.2 million, if recognized, would affect the effective tax rate. The Company does not expect its unrecognized tax benefits to significantly increase or decrease over the next 12 months.

The Company conducts business globally, and as a result, the Company or one or more of its subsidiaries files income tax returns in the United States federal jurisdiction and various state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world.

The following table summarizes the open tax years for each major jurisdiction:


Jurisdiction		Open Tax Years
United States Federal		2002-2011
Australia		2002-2011
Canada		2004-2011
United Kingdom		2004-2011
Netherlands		2007-2011

The Company has closed certain federal and provincial income tax examinations in Canada for the years through 2005 (federal) and 2001 through 2005 (provincial) with all assessments being received. The Company has concluded an examination in the Netherlands for tax years through 2006. Based on the final settlement, the Company reversed its remaining liability in the fourth quarter of 2008 and paid those liabilities during 2009. The Company is also currently under examination in other foreign tax jurisdictions, none of which are individually material. The IRS concluded its audit of Arbinet for tax years 2007, 2008 and 2009.

Fair Value Of Financial Instruments And Derivatives

10. FAIR VALUE OF FINANCIAL INSTRUMENTS AND DERIVATIVES

The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to relatively short periods to maturity. The estimated aggregate fair value of the Company's debt, based on quoted market prices, was $235.4 million and $247.8 million at December 31, 2011 and 2010, respectively. The aggregate carrying value of the Company's debt was $236.1 million and $242.2 million at December 31, 2011 and 2010, respectively.

See table below for a summary of the Company's financial instruments accounted for at fair value on a recurring basis:


			Fair Value as of December 31, 2011, using:
	December 31, 2011		Quoted prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Liabilities:
Contingent Value Rights (CVRs)	$	16,196		—		16,196		—

Total	$	16,196		—		16,196		—


			Fair Value as of December 31, 2010, using:
	December 31, 2010		Quoted prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Total	$	19,098		—		19,098		—

Successor

The CVRs are marked to fair value at each balance sheet date. The change in value is reflected in our consolidated statements of operations. Estimates of fair value represent the Company's best estimates based on a Black-Scholes pricing model using the following assumptions: (1) expected life of 7.5 years; (2) risk-free rate of 1.44%; (3) expected volatility of 48.17%; (4) dividend yield of 0%; (5) exercise price of $35.95; (6) stock price of $12.66. During the years ended December 31, 2011 and 2010 and the six months ended December 31, 2009, $2.9 million, ($13.7) million and ($2.8) million, respectively, of income (expense) was recognized as a result of marking the CVRs to their fair value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Stockholders' Equity (Deficit) [Abstract]

Stockholders' Equity (Deficit)

12. STOCKHOLDERS' EQUITY (DEFICIT)

As of December 31, 2011 there are 13,741,020 shares of common stock outstanding.

On the Effective Date of the Plan of Reorganization, all existing shares of Old Common Stock were cancelled and holders thereof received their pro rata share of contingent value rights to acquire up to 2,665,000 shares of New Common Stock on terms described under the Contingent Value Rights Distribution Agreement in Note 2. Holders of IHC's 14¹/4% Senior Secured Notes and the Holding Senior Notes received 9,600,000 shares of New Common Stock. In addition, the Company recorded $1.0 million of equity related to the issuance of the warrants.

On February 28, 2011, the Company completed its previously announced acquisition of Arbinet. Upon the closing of the merger, each share of Arbinet common stock was cancelled and converted into the right to receive 0.5817 shares of Primus common stock. Arbinet stockholders received cash in lieu of any fractional shares of Primus common stock that they were otherwise entitled to receive in the merger. In connection with the merger, Primus issued 3,232,812 shares of its common stock to former Arbinet stockholders in exchange for their shares of Arbinet common stock, and reserved for issuance approximately 95,000 additional shares of its common stock in connection with its assumption of Arbinet's outstanding options, warrants, stock appreciation rights and restricted stock units. See Note 5—"Acquisitions," for further detail concerning the transaction.

On August 8, 2011, the Company's board of directors authorized a stock repurchase program of up to $15 million of its common stock through August 8, 2013. Under the stock repurchase program, the Company may repurchase common stock from time to time in the open-market, privately negotiated transactions or block trades. There is no guarantee as to the exact number of shares, if any, that the Company will repurchase. The stock repurchase program may be modified, terminated or extended at any time without prior notice. The Company has established a committee consisting of its lead director, chief executive officer and chief financial officer to oversee the administration of the stock repurchase program. During the year ended December 31, 2011, the Company repurchased 31,626 shares at a weighted average price of $11.92 per share under the stock repurchase plan.

The following table provides a reconciliation of beginning and ending shares (in thousands):

Share-Based Compensation

12 Months Ended

Dec. 31, 2011

Share-Based Compensation [Abstract]

Share-Based Compensation

13. SHARE-BASED COMPENSATION

On the Effective Date, pursuant to the Plan, the Predecessor's employee stock compensation plan (the "Equity Incentive Plan") was cancelled and the Group's Management Compensation Plan became effective. The Management Compensation Plan provides that awards may be granted for up to 1,000,000 shares of New Common Stock, subject to adjustment in the case of certain changes in capitalization of reorganized Group, including, among other things, a reorganization, merger, consolidation, spin-off, combination, repurchase, share exchange, or other similar corporate transaction or event that affects the New Common Stock. The maximum aggregate number of shares of New Common Stock that may be granted during any fiscal year to any single individual who is likely to be a "covered employee" within the meaning of section 162(m)(3) of the Internal Revenue Code is 600,000, in the case of stock options or stock appreciation rights, and 400,000, in the case of restricted stock or other stock-based awards (other than stock appreciation rights).

The Compensation Committee (the "Committee") of the Board of Directors of Group administers the Management Compensation Plan. The Committee has broad authority to administer, construe and interpret the Management Compensation Plan; however, it may not take any action with respect to an award that would be treated, for accounting purposes, as a "repricing" of an award unless the action is approved by the shareholders of Group.

The Management Compensation Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock, restricted stock units, and other stock-based or cash-based performance awards (collectively, "awards").

The Company follows guidance which addresses the accounting for stock-based payment transactions whereby an entity receives employee services in exchange for either equity instruments of the enterprise or liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. The guidance generally requires that such transactions be accounted for using a fair-value based method and share-based compensation expense be recorded, based on the grant date fair value, estimated in accordance with the guidance, for all new and unvested stock awards that are ultimately expected to vest as the requisite service is rendered.

The Company's equity incentive plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock, restricted stock units, and other share-based or cash-based performance awards. The Company typically issues new shares of common stock upon the exercise of stock options, as opposed to using treasury shares.

There were 41,666 and 40,000 options granted during the year ended December 31, 2011 and 2010, respectively. The weighted average fair value at date of grant for options granted during the years ended December 31, 2011 and 2010 and six months ended December 31, 2009 was $5.11, $3.07, and $4.00, respectively, per option. Options granted prior to July 1, 2009 were cancelled in conjunction with the cancellation of the Company's Old Common Stock pursuant to the terms of our Plan of Reorganization and we have no continuing obligations with respect to the options issued prior to July 1, 2009. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions shown as a weighted average for the year:


	Successor									Predecessor
	Year Ended December 31, 2011			Year Ended December 31, 2010			Six Months Ended December 31, 2009			Six Months Ended July 1, 2009
Expected option life		6 Years			4 Years			4 Years			4 Years
Risk-free interest rate		1.12 - 1.91	%		1.20	%		2.00	%		2.00	%
Expected volatility		41.25 - 43.32	%		47.00	%		42.00	%		42.00	%
Dividend yield		0	%		0	%		0	%		0	%

Successor

Total share-based compensation expense recognized by the Company in the years ended December 31, 2011 and 2010, and six months ended December 31, 2009 was $5.2 million, $1.6 million and $1.2 million, respectively. Most of the Company's stock awards vest ratably during the vesting period. The Company recognizes compensation expense for equity awards, reduced by estimated forfeitures, using the straight-line basis.

Predecessor

Total share-based compensation expense recognized by the Company in the six months ended July 1, 2009 was $27 thousand.

At the closing of the acquisition of Arbinet on February 28, 2011, the Company reserved approximately 95,000 additional shares of its common stock for issuance in connection with its assumption of Arbinet's outstanding options, warrants, stock appreciation rights and restricted stock units.

Restricted Stock Units (RSUs)

A summary of the Company's restricted stock units activity during the year ended December 31, 2011 is as follows:

As of December 31, 2011, the Company had 0.7 million unvested RSUs outstanding with respect to $3.9 million of compensation expense that is expected to be recognized over the weighted average remaining vesting period of 2.0 years. The number of unvested RSUs expected to vest is 0.6 million.

Stock Options and Stock Appreciation Rights

A summary of the Company's stock option and stock appreciation rights activity during the year ended December 31, 2011 is as follows:

Outstanding—December 31, 2011		129,080		$	11.34

Eligible for exercise		90,713		$	11.49

The following table summarizes the intrinsic values and remaining contractual terms of the Company's stock options and stock appreciation rights:


	Intrinsic Value		Weighted Average Remaining Life in Years
Options outstanding—December 31, 2011	$	192,360		8.4
Options exercisable—December 31, 2011		125,751		8.0

During the year ended December 31, 2011, 0.1 million options were exercised with an intrinsic value of $0.3 million. As of December 31, 2011, the Company had approximately 38,000 unvested stock options and stock appreciation rights outstanding of which $0.1 million of compensation expense is expected to be recognized over the weighted average remaining period of 1.4 years.

Operating Segment And Related Information [Abstract]

Operating Segment And Related Information

16. OPERATING SEGMENT AND RELATED INFORMATION

The Company has four reportable geographic segments—United States, Canada, Asia-Pacific and Europe. The Company has five reportable operating segments based on management's organization of the enterprise—United States, Canada, Australia, the International Carrier Services ("ICS") business from the United States and Europe, which is managed as a separate global segment, into which Arbinet is integrated, and Other. The Company evaluates the performance of its segments and allocates resources to them based upon net revenue and income (loss) from operations. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Net revenue by geographic segment is reported on the basis of where services are provided. All inter-segment revenues are eliminated. The Company has no single customer representing greater than 10% of its revenues. Corporate assets, capital expenditures and property and equipment are included in the United States segment, while corporate expenses are presented separately in income (loss) from operations. The assets of the ICS business are indistinguishable from the respective geographic segments. Therefore, any reporting related to the ICS business for assets or other balance sheet items is impractical.

Summary information with respect to the Company's operating segments is as follows (in thousands):

Basic And Diluted Income (Loss) Per Common Share [Abstract]

Basic And Diluted Income (Loss) Per Common Share

21. BASIC AND DILUTED INCOME (LOSS) PER COMMON SHARE

Basic income (loss) per common share is calculated by dividing income (loss) attributable to common stockholders by the weighted average common shares outstanding during the period. Diluted income per common share adjusts basic income per common share for the effects of potentially dilutive common share equivalents.

Potentially dilutive common shares for Successor include the dilutive effects of common shares issuable under the Successor's Management Compensation Plan, including stock options, stock warrants and restricted stock units (RSUs), using the treasury stock method, as well as contingent value rights (CVRs).

Successor

The Company had no dilutive common share equivalents during the year ended December 31, 2011, due to the results of operations being a net loss. For the year ended December 31, 2011, the following were potentially dilutive but were excluded from the calculation of diluted loss per common share due to their antidilutive effect:

•

0.8 million shares issuable upon exercise of stock options and RSUs under the Successor's Management Compensation Plan;

•

4.5 million shares issuable upon exercise of stock warrants; and

•

2.7 million shares issuable upon exercise of CVRs.

The Company had no dilutive common share equivalents during the year ended December 31, 2010, due to the results of operations being a net loss. For the year ended December 31, 2010, the following were potentially dilutive but were excluded from the calculation of diluted loss per common share due to their antidilutive effect:

•

0.6 million shares issuable upon exercise of stock options and RSUs under the Successor's Management Compensation Plan;

•

4.5 million shares issuable upon exercise of stock warrants; and

•

2.7 million shares issuable upon exercise of CVRs.

For the six months ended December 31, 2009, the following could potentially dilute income per common share in the future but was excluded from the calculation of diluted income per common share due to its antidilutive effect:

•

0.7 million shares issuable upon exercise of stock options and RSUs under the Successor's Management Compensation Plan;

•

4.5 million shares issuable upon exercise of stock warrants; and

•

2.7 million shares issuable upon exercise of CVRs.

Predecessor

Potentially dilutive common shares for Predecessor primarily included the dilutive effects of common shares issuable under Predecessor's Equity Incentive Plan computed using the treasury stock method and the dilutive effects of shares issuable upon conversion of its 5% Exchangeable Senior Notes, the Step Up Convertible Subordinated Debentures, the 3 ³/4% Convertible Senior Notes and the 2000 Convertible Subordinated Debentures.

For the six months ended July 1, 2009, the following was potentially dilutive but was excluded from the calculation of diluted income per common share due to its antidilutive effect:

•

7.8 million shares issuable under the Predecessor's Equity Incentive Plan.

A calculation of basic income (loss) per common share to diluted income (loss) per common share is set forth below (in thousands, except per share amounts):

Professional fees include financial, legal and other services directly associated with the reorganization process. Payments for reorganization expense for the six months ended December 31, 2009 were $7.6 million. Payments for reorganization expense for the six months ended July 1, 2009 were $4.6 million. In accordance with ASC No. 852, the Company ceased amortization of debt premiums, discounts and deferred financing costs related to the liabilities subject to compromise on the Petition Date. The $3.5 million of unamortized debt premiums and discounts have been written off and recorded as a gain, offset by the expensing of $3.6 million of unamortized deferred financing costs, as an adjustment to the net carrying value of the pre-petition debt. Long term debt was further reduced by $20.5 million of future interest payable that previously had been recorded as a portion of long-term obligations for the 14 ¹/4% Senior Secured Notes and 5% Exchangeable Senior Notes as the issuance of these notes had been deemed troubled debt restructurings. Upon emergence from bankruptcy, Predecessor debt in the amount of $439.6 million was written off along with the accrued interest related to this debt in the amount of $11.5 million. In addition, the Successor Company issued $123.5 million of new debt upon emergence and issued 4.8 million shares of Successor Company common stock to the former holders of the Company's debt.
