Basis of Presentation
Basis of Presentation	In the opinion of management, the financial information furnished herein reflects all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods specified. These adjustments consist only of normal recurring accruals except as disclosed herein. Because of seasonal and other factors, results for interim periods are not necessarily indicative of the results to be expected for the full year. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions about future events. These estimates and assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and the reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, outsourcing assets, marketable software, goodwill and other long-lived assets, legal contingencies, indemnifications, and assumptions used in the calculation for systems integration projects, income taxes and retirement and other post-employment benefits, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. The company's accounting policies are set forth in detail in note 1 of the notes to the consolidated financial statements in the company's Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission. Such Annual Report also contains a discussion of the company's critical accounting policies. The company believes that these critical accounting policies affect its more significant estimates and judgments used in the preparation of the company's consolidated financial statements. There have been no changes in the company's critical accounting policies from those disclosed in the company's Annual Report on Form 10-K for the year ended December 31, 2010.

Description containing the entire organization, consolidation and basis of presentation of financial statements disclosure. May be provided in more than one note to the financial statements, as long as users are provided with an understanding of (1) the significant judgments and assumptions made by an enterprise in determining whether it must consolidate a VIE and/or disclose information about its involvement with a VIE, (2) the nature of restrictions on a consolidated VIE's assets reported by an enterprise in its statement of financial position, including the carrying amounts of such assets, (3) the nature of, and changes in, the risks associated with an enterprise's involvement with the VIE, and (4) how an enterprise's involvement with the VIE affects the enterprise's financial position, financial performance, and cash flows.

Discontinued Operations

Discontinued Operations

a. On April 30, 2010, the company completed the sale of its health information management (HIM) business, and on August 31, 2010, the company completed the sale of its UK-based Unisys Insurance Services Limited (UISL) business, which provides business process outsourcing (BPO) services to the UK life and pensions industry. In connection with the sale of UISL, the company paid $4.9 million during the three months ended March 31, 2011 and has payment obligations of approximately $14.5 million to be paid ratably over the next three quarterly periods.

The results of discontinued operations for the three months ended March 31, 2010 are as follows (in millions of dollars):

Foreign Currency Losses
Foreign Currency Losses	b. Due to cumulative inflation of approximately 100 percent or more over the last 3-year period, the company's Venezuelan subsidiary has applied highly inflationary accounting beginning January 1, 2010. For those international subsidiaries operating in highly inflationary economies, the U.S. dollar is the functional currency, and as such, nonmonetary assets and liabilities are translated at historical exchange rates, and monetary assets and liabilities are translated at current exchange rates. Exchange gains and losses arising from translation are included in other income (expense), net. Effective January 11, 2010, the Venezuelan government devalued the Bolivar Fuerte by 50 percent by resetting the official exchange rate from 2.15 to the U.S. dollar to 4.30 to the U.S. dollar. As a result, the company recorded a foreign exchange loss in the first quarter of 2010 of approximately $20 million. The company has used and continues to use the official exchange rate for translation purposes. At March 31, 2011, the company's operations in Venezuela had net monetary assets denominated in local currency of approximately $18 million.

Fair Value Measurements	3 Months Ended
Fair Value Measurements	Mar. 31, 2011
Fair Value Measurements
Fair Value Measurements	e. Due to its foreign operations, the company is exposed to the effects of foreign currency exchange rate fluctuations on the U.S. dollar, principally related to intercompany account balances. The company uses derivative financial instruments to reduce its exposure to market risks from changes in foreign currency exchange rates on such balances. The company enters into foreign exchange forward contracts, generally having maturities of one month, which have not been designated as hedging instruments. At March 31, 2011 and 2010, the notional amount of these contracts was $27.4 million and $34.0 million, respectively. At March 31, 2011 and 2010, the fair value of such contracts was a net gain of $.2 million and a net gain of $.1 million, respectively, of which $.2 million and $7.6 million, respectively, has been recognized in "Prepaid expenses and other current assets" and zero and $7.5 million, respectively, has been recognized in "Other accrued liabilities" in the company's consolidated balance sheet. For the three months ended March 31, 2011 and 2010, changes in the fair value of these instruments were a loss of $.4 million and a gain of $.2 million, respectively, which has been recognized in earnings in "Other income (expense), net" in the company's consolidated statement of income. The fair value of these forward contracts is based on quoted prices for similar but not identical financial instruments; as such, the inputs are considered Level 2 inputs. Financial assets with carrying values approximating fair value include cash and cash equivalents and accounts receivable. Financial liabilities with carrying values approximating fair value include accounts payable and other accrued liabilities. The carrying amounts of these financial assets and liabilities approximate fair value due to their short maturities. At March 31, 2011 and December 31, 2010, the carrying amount of long-term debt was less than fair value, which is based on market prices (Level 2 inputs), of such debt by approximately $100 million and $140 million, respectively.

- Definition

This element represents the disclosure related to the fair value measurement of assets and liabilities which includes [financial] instruments measured at fair value that are classified in stockholders' equity. Such assets and liabilities may be measured on a recurring or nonrecurring basis. The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods.

Stock Options

Stock Options

Stock Options

f. Under stockholder approved stock-based plans, stock options, stock appreciation rights, restricted stock and restricted stock units may be granted to officers, directors and other key employees. At March 31, 2011, 4.7 million shares of unissued common stock of the company were available for granting under these plans.

The fair value of stock option awards was estimated using the Black-Scholes option pricing model with the following assumptions and weighted-average fair values:


	Three Months Ended March 31,
	2011			2010
Weighted-average fair value of grant	$	20.25		$	17.97
Risk-free interest rate		1.71	%		1.74	%
Expected volatility		71.31	%		72.20	%
Expected life of options in years		3.62			3.63
Expected dividend yield		—			—

Restricted stock unit awards may contain time-based units, performance-based units or a combination of both. Each performance-based unit will vest into zero to 1.5 shares depending on the degree to which the performance goals are met. Compensation expense resulting from these awards is recognized as expense ratably for each installment from the date of grant until the date the restrictions lapse and is based on the fair market value at the date of grant and the probability of achievement of the specific performance-related goals.

The company records all share-based expense in selling, general and administrative expense.

During the three months ended March 31, 2011 and 2010, the company recorded $6.3 million and $4.9 million of share-based compensation expense, respectively, which is comprised of $2.4 million and $2.1 million of restricted stock unit expense and $3.9 million and $2.8 million of stock option expense, respectively.

A summary of stock option activity for the three months ended March 31, 2011 follows (shares in thousands):


Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (years)		Aggregate Intrinsic Value ($ in millions)
Outstanding at December 31, 2010		3,125		$	85.78
Granted		607			38.66
Exercised		(140	)		9.24
Forfeited and expired		(623	)		178.55


Outstanding at March 31, 2011		2,969			60.38		2.92	$	17.7


Expected to vest at March 31, 2011		1,195			30.93		4.13		6.0


Exercisable at March 31, 2011		1,720			81.73		2.03		11.6

The aggregate intrinsic value represents the total pretax value of the difference between the company's closing stock price on the last trading day of the period and the exercise price of the options, multiplied by the number of in-the-money stock options that would have been received by the option holders had all option holders exercised their options on March 31, 2011. The intrinsic value of the company's stock options changes based on the closing price of the company's stock. The total intrinsic value of options exercised for the three months ended March 31, 2011 and 2010 was $4.0 million and $4.9 million, respectively. As of March 31, 2011, $14.5 million of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 2.3 years.

A summary of restricted stock unit activity for the three months ended March 31, 2011 follows (shares in thousands):

The fair value of restricted stock units is determined based on the trading price of the company's common shares on the date of grant. The aggregate weighted-average grant-date fair value of restricted stock units granted during the three months ended March 31, 2011 and 2010 was $10.9 million and $6.7 million, respectively. As of March 31, 2011, there was $11.4 million of total unrecognized compensation cost related to outstanding restricted stock units granted under the company's plans. That cost is expected to be recognized over a weighted-average period of 2.4 years. The aggregate weighted-average grant-date fair value of restricted share units vested during the three months ended March 31, 2011 and 2010 was $4.8 million and $3.5 million, respectively.

Common stock issued upon exercise of stock options or upon lapse of restrictions on restricted stock units is newly issued shares. Cash received from the exercise of stock options for the three months ended March 31, 2011 and 2010 was $1.3 million and $1.1 million, respectively. The company is currently not recognizing any tax benefits from the exercise of stock options or upon issuance of stock upon lapse of restrictions on restricted stock units in light of its tax position. Tax benefits resulting from tax deductions in excess of the compensation costs recognized are classified as financing cash flows.

Segment Information

Segment Information

g. The company has two business segments: Services and Technology. Revenue classifications by segment are as follows: Services – systems integration and consulting, outsourcing, infrastructure services and core maintenance; Technology – enterprise-class servers and other technology.

The accounting policies of each business segment are the same as those followed by the company as a whole. Intersegment sales and transfers are priced as if the sales or transfers were to third parties. Accordingly, the Technology segment recognizes intersegment revenue and manufacturing profit on hardware and software shipments to customers under Services contracts. The Services segment, in turn, recognizes customer revenue and marketing profits on such shipments of company hardware and software to customers. The Services segment also includes the sale of hardware and software products sourced from third parties that are sold to customers through the company's Services channels. In the company's consolidated statements of income, the manufacturing costs of products sourced from the Technology segment and sold to Services customers are reported in cost of revenue for Services.

Also included in the Technology segment's sales and operating profit are sales of hardware and software sold to the Services segment for internal use in Services engagements. The amount of such profit included in operating income of the Technology segment for the three months ended March 31, 2011 and 2010 was $.8 million and $.4 million, respectively. The profit on these transactions is eliminated in Corporate.

The company evaluates business segment performance on operating income exclusive of restructuring charges and unusual and nonrecurring items, which are included in Corporate. Effective January 1, 2011, the company changed the measurement of segment performance that it evaluates to exclude pension income or expense. Prior periods have been reclassified to conform to the 2011 presentation. All other corporate and centrally incurred costs are allocated to the business segments based principally on revenue, employees, square footage or usage.

Accounting Standards	3 Months Ended
Accounting Standards	Mar. 31, 2011
Accounting Standards
Accounting Standards	j. Effective January 1, 2011, the company adopted two accounting standards issued by the Financial Accounting Standards Board that amend revenue recognition guidance. The first standard supersedes certain prior accounting guidance and requires an entity to allocate arrangement consideration at the inception of an arrangement to all of its deliverables based on their relative standalone selling prices (i.e., the relative-selling-price method). The standard eliminates the use of the residual method of allocation and requires the relative-selling-price method in all circumstances in which an entity recognizes revenue for an arrangement with multiple deliverables subject to this standard. The second standard amends prior software revenue recognition accounting guidance by excluding from the scope of such prior guidance tangible products that contain both software elements and non-software elements that function together to deliver the tangible product's essential functionality. The company has adopted the new standards prospectively for revenue arrangements entered into or materially modified on or after January 1, 2011. In certain of the company's arrangements, revenue was previously deferred for certain deliverables included in multiple element arrangements where the arrangements also included undelivered services for which the company was unable to demonstrate fair value pursuant to previous standards. The new standards require deliverables for which revenue was previously deferred to be separated and recognized as delivered, rather than combined with undelivered items and recognized over the longest service delivery period. If the new standards were applied to transactions entered into or materially modified in the year ended December 31, 2010, it would not have resulted in a material change to the company's reported revenue for 2010. The company is not able to reasonably estimate the effect of adopting these standards on future periods as the impact will vary based on the nature and volume of new or materially modified deals in any given period.

Revenue Recognition	3 Months Ended
Revenue Recognition	Mar. 31, 2011
Revenue Recognition
Revenue Recognition	k. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the fee is fixed or determinable, and collectability is probable. Revenue from hardware sales with standard payment terms is recognized upon the passage of title and the transfer of risk of loss. Outside the United States, the company recognizes revenue even if it retains a form of title to products delivered to customers, provided the sole purpose is to enable the company to recover the products in the event of customer payment default and the arrangement does not prohibit the customer's use of the product in the ordinary course of business. Revenue from software licenses with standard payment terms is recognized at the inception of the initial license term and upon execution of an extension to the license term. The company also enters into multiple-element arrangements, which may include any combination of hardware, software or services. For example, a client may purchase an enterprise server that includes operating system software. In addition, the arrangement may include post-contract support for the software and a contract for post-warranty maintenance for service of the hardware. These arrangements consist of multiple deliverables, with hardware and software delivered in one reporting period and the software support and hardware maintenance services delivered across multiple reporting periods. In another example, the company may provide desktop managed services to a client on a long term multiple year basis and periodically sell hardware and software products to the client. The services are provided on a continuous basis across multiple reporting periods and the hardware and software products are delivered in one reporting period. To the extent that a deliverable in a multiple-deliverable arrangement is subject to specific guidance, that deliverable is accounted for in accordance with such specific guidance. Examples of such arrangements may include leased hardware which is subject to specific leasing guidance or software which is subject to specific software revenue recognition guidance. In these transactions, the company allocates the total revenue to be earned under the arrangement among the various elements based on a selling price hierarchy. The selling price for a deliverable is based on its vendor specific objective evidence (VSOE) if available, third party evidence (TPE) if VSOE is not available, or the best estimated selling price (ESP) if neither VSOE nor TPE is available. VSOE of selling price is based upon the normal pricing and discounting practices for those products and services when sold separately. TPE of selling price is based on evaluating largely similar and interchangeable competitor products or services in standalone sales to similarly situated customers. ESP is established considering factors such as margin objectives, discounts off of list prices, market conditions, competition and other factors. ESP represents the price at which the company would transact for the deliverable if it were sold by the company regularly on a standalone basis. For multiple-element arrangements that involve the licensing, selling or leasing of software, for software and software-related elements, the allocation of revenue is based on VSOE. There may be cases in which there is VSOE of selling price of the undelivered elements but no such evidence for the delivered elements. In these cases, the residual method is used to allocate the arrangement consideration. Under the residual method, the amount of consideration allocated to the delivered elements equals the total arrangement consideration less the aggregate VSOE of selling price of the undelivered elements. For multiple-element arrangements for products or services that (a) do not include the licensing, selling or leasing of software, or (b) contain software that is incidental to the products or services as a whole or (c) contain software components that are sold, licensed or leased with tangible products when the software components and non-software components (i.e., the hardware and software) of the tangible product function together to deliver the tangible product's essential functionality (e.g. sales of the company's enterprise-class servers including hardware and software), the allocation of revenue is based on the relative selling prices of each of the deliverables in the arrangement based on the selling price hierarchy, discussed above. The company recognizes revenue on delivered elements only if: (a) any undelivered products or services are not essential to the functionality of the delivered products or services, (b) the company has an enforceable claim to receive the amount due in the event it does not deliver the undelivered products or services, (c) there is evidence of the selling price for each undelivered products or services, and (d) the revenue recognition criteria otherwise have been met for the delivered elements. Otherwise, revenue on delivered elements is recognized as the undelivered elements are delivered. The company evaluates each deliverable in an arrangement to determine whether they represent separate units of accounting. A delivered element constitutes a separate unit of accounting when it has standalone value and there is no customer-negotiated refund or return rights for the delivered elements. If these criteria are not met, the deliverable is combined with the undelivered elements and the allocation of the arrangement consideration and revenue recognition are determined for the combined unit as a single unit. Revenue from hardware sales and software licenses with extended payment terms is recognized as payments from customers become due (assuming that all other conditions for revenue recognition have been satisfied). Revenue for operating leases is recognized on a monthly basis over the term of the lease and for sales-type leases at the inception of the lease term. Revenue from equipment and software maintenance and post-contract support is recognized on a straight-line basis as earned over the terms of the respective contracts. Cost related to such contracts is recognized as incurred. Revenue and profit under systems integration contracts are recognized either on the percentage-of-completion method of accounting using the cost-to-cost method, or when services have been performed, depending on the nature of the project. For contracts accounted for on the percentage-of-completion basis, revenue and profit recognized in any given accounting period are based on estimates of total projected contract costs. The estimates are continually reevaluated and revised, when necessary, throughout the life of a contract. Any adjustments to revenue and profit resulting from changes in estimates are accounted for in the period of the change in estimate. When estimates indicate that a loss will be incurred on a contract upon completion, a provision for the expected loss is recorded in the period in which the loss becomes evident. Revenue from time and materials service contracts and outsourcing contracts is recognized as the services are provided using either an objective measure of output or on a straight-line basis over the term of the contract.

Commitments and Contingencies
Commitments and Contingencies	l. There are various lawsuits, claims, investigations and proceedings that have been brought or asserted against the company, which arise in the ordinary course of business, including actions with respect to commercial and government contracts, labor and employment, employee benefits, environmental matters, intellectual property, and non-income tax and employment compensation in Brazil. The company records a provision for these matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Any provisions are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information and events pertinent to a particular matter. The company believes that it has valid defenses with respect to legal matters pending against it. Based on its experience, the company also believes that the damage amounts claimed in the lawsuits disclosed below are not a meaningful indicator of the company's potential liability. Litigation is inherently unpredictable, however, and it is possible that the company's results of operations or cash flow could be materially affected in any particular period by the resolution of one or more of the legal matters pending against it. The company had a competitively awarded contract with the Transportation Security Administration (TSA) providing for the establishment of secure information technology environments in airports. The Civil Division of the Department of Justice, working with the Inspector General's Office of the Department of Homeland Security, is reviewing issues relating to labor categorization and overtime on the TSA contract. The Civil Division is also reviewing issues relating to cyber intrusion protection under the TSA and follow-on contracts. The company is working cooperatively with TSA and the Civil Division. The company has commenced preliminary settlement discussions with these government agencies regarding labor categorization and overtime. The company cannot now predict the duration or outcome of these discussions. The company has contracts with the General Services Administration (GSA), known as Multiple Award Schedule Contracts, under which various U.S. governmental agencies can purchase products and services from the company. Auditors from the GSA's Office of Inspector General have been reviewing the company's compliance with the disclosure and pricing provisions under two of these contracts, and whether the company has potentially overcharged the government under the contracts. Separately, the company has made voluntary disclosures about these matters to the responsible GSA contracting officers. The company has been providing pricing and other information to the GSA auditors and is working cooperatively with them. One of these matters is now completed, with the company paying a de minimis amount to the GSA. The audit on the other contract is in its preliminary stages, and the company cannot predict the outcome at this time. In April 2007, the Ministry of Justice of Belgium sued Unisys Belgium SA-NV, a Unisys subsidiary (Unisys Belgium), in the Court of First Instance of Brussels. The Belgian government had engaged the company to design and develop software for a computerized system to be used to manage the Belgian court system. The Belgian State terminated the contract and in its lawsuit has alleged that the termination was justified because Unisys Belgium failed to deliver satisfactory software in a timely manner. It claims damages of approximately 28 million Euros. Unisys Belgium has filed its defense and counterclaim in the amount of approximately 18.5 million Euros. The company believes it has valid defenses to the claims and contends that the Belgian State's termination of the contract was unjustified. In December 2007, Lufthansa AG sued Unisys Deutschland GmbH, a Unisys subsidiary (Unisys Germany), in the District Court of Frankfurt, Germany, for allegedly failing to perform properly its obligations during the initial phase of a 2004 software design and development contract relating to a Lufthansa customer loyalty program. Under the contract, either party was free to withdraw from the project at the conclusion of the initial design phase. Rather than withdraw, Lufthansa instead terminated the contract and failed to pay the balance owed to Unisys Germany for the initial phase. Lufthansa's lawsuit alleges that Unisys Germany breached the contract by failing to deliver a proper design for the new system and seeks approximately 21.4 million Euros in damages. The company believes it has valid defenses and has filed its defense and a counterclaim in the amount of approximately 1.5 million Euros. The litigation is proceeding. Notwithstanding that the ultimate results of the lawsuits, claims, investigations and proceedings that have been brought or asserted against the company are not currently determinable, the company believes that at March 31, 2011, it has adequate provisions for any such matters.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2011
Income Taxes
Income Taxes	m. Accounting rules governing income taxes require that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. These rules also require that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or the entire deferred tax asset will not be realized. The company evaluates the realizability of its deferred tax assets by assessing its valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization are the company's historical profitability, forecast of future taxable income and available tax-planning strategies that could be implemented to realize the net deferred tax assets. The company uses tax-planning strategies to realize or renew net deferred tax assets to avoid the potential loss of future tax benefits. A full valuation allowance is currently maintained for all U.S. and certain foreign deferred tax assets in excess of deferred tax liabilities. The company will record a tax provision or benefit for those international subsidiaries that do not have a full valuation allowance against their net deferred tax assets. Any profit or loss recorded for the company's U.S. continuing operations will have no provision or benefit associated with it due to full valuation allowance, except with respect to benefits related to income from discontinued operations. As a result, the company's provision or benefit for taxes will vary significantly depending on the geographic distribution of income. Internal Revenue Code Sections 382 and 383 provide annual limitations with respect to the ability of a corporation to utilize its net operating loss (as well as certain built-in losses) and tax credit carryforwards, respectively (Tax Attributes), against future U.S. taxable income, if the corporation experiences an "ownership change." In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. The company regularly monitors ownership changes (as calculated for purposes of Section 382). Based on currently available information, the company believes that an ownership change occurred as of January 2011 for purposes of the rules described above. Moreover, any future transaction or transactions and the timing of such transaction or transactions could trigger an additional ownership change under Section 382. As a result of an ownership change, utilization of the company's Tax Attributes will be subject to an estimated overall annual limitation determined in part by multiplying the total aggregate market value of the company's common stock immediately preceding the ownership change by the applicable long-term tax-exempt rate (which is 4.10% for January 2011), possibly subject to increase based on the built-in gain if any, in the company's assets at the time of the ownership change. Any unused annual limitation may be carried over to later years. Future U.S. taxable income may not be fully offset by existing Tax Attributes, if such income exceeds the company's annual limitation. However, based on presently available information and the existence of tax planning strategies, currently the company does not expect to incur a cash tax liability in the near term. The company maintains a full valuation allowance against the realization of all U.S. deferred tax assets as well as certain foreign deferred tax assets in excess of deferred tax liabilities.

Stockholders' Equity	3 Months Ended
Stockholders' Equity	Mar. 31, 2011
Stockholders' Equity
Stockholders' Equity	n. On February 28, 2011, the company sold 2,587,500 shares of 6.25% mandatory convertible preferred stock for net proceeds of $249.7 million. Each share of mandatory convertible preferred stock will automatically convert on March 1, 2014 into between 2.1899 and 2.6717 shares of the company's common stock, subject to adjustment, depending on the volume weighted average price per share of the company's common stock over the 20 consecutive trading days ending on the third trading day immediately preceding the mandatory conversion date. At any time prior to March 1, 2014, holders may elect to convert all or a portion of their shares of the mandatory convertible preferred stock at the minimum conversion rate of 2.1899 shares of the company's common stock, subject to adjustment. The company will pay dividends on each share of the mandatory convertible preferred stock on a cumulative basis at an annual rate of 6.25% on the initial liquidation preference of $100 per share (equivalent to $6.25 per year per share). Dividends will accrue and cumulate from the date of issuance and, to the extent the company has lawfully available funds to pay dividends and the company's Board of Directors or an authorized committee of the Board of Directors declares a dividend payable, the company will pay dividends on March 1, June 1, September 1 and December 1 of each year prior to March 1, 2014 in cash and on March 1, 2014 or any earlier conversion date in cash, shares of the company's common stock, or a combination thereof, at the company's election. The first dividend payment will be June 1, 2011. The annualized dividend on the mandatory convertible preferred stock will be approximately $16.2 million until conversion. On March 30, 2011, the net proceeds from the sale of the mandatory convertible preferred stock were used to redeem an aggregate principal amount of $124.7 million of the company's senior secured notes due 2014 and an aggregate principal amount of $86.3 million of the company's senior secured notes due 2015 under the provisions of the indentures relating to the notes that allow the company to redeem, at its option, up to 35% of the original principal amount of each series of notes from the net cash proceeds of one or more equity offerings. As a result of these redemptions, the company recognized a charge of $31.8 million in "Other income (expense), net" in the three months ended March 31, 2011, which was comprised of $28.2 million of premium paid and $3.6 million for the write off of unamortized discounts, issuance costs and gains related to the portion of the notes redeemed. On April 11, 2011, the company purchased $44.1 million of its senior secured notes due 2014 and $134.8 million of its senior secured notes due 2015 that had been tendered into a cash tender offer conducted by the company. As a result of this purchase of notes, the company will recognize a charge of approximately $45.6 million in "Other income (expense), net" in the three months ending June 30, 2011, which is comprised of $42.1 million of premium and expenses paid and $3.5 million for the write off of unamortized discounts, issuance costs and gains related to the portion of the notes purchased.
