	1.    General
	The accompanying unaudited condensed consolidated financial statements of Weatherford International Ltd.  (the "Company") are prepared in accordance with U.S. generally accepted accounting principles and include all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly our Condensed Consolidated Balance Sheet at September 30, 2013, Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Cash Flows for the three and nine months ended September 30, 2013 and 2012. When referring to "Weatherford" and using phrases such as "we," "us," and "our," the intent is to refer to Weatherford International Ltd., a Swiss joint-stock company, and its subsidiaries as a whole or on a regional basis, depending on the context in which the statements are made.
	Although we believe the disclosures in these financial statements are adequate, certain information relating to our organization and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to U.S. Securities and Exchange Commission ("SEC") rules and regulations.  These financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2012 included in our Annual Report on Form 10-K.  The results of operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results expected for the year ending December 31, 2013.
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period and disclosure of contingent assets and liabilities.  On an ongoing basis, we evaluate our estimates and assumptions, including those related to uncollectible accounts receivable, lower of cost or market of inventories, equity investments, intangible assets and goodwill, property, plant and equipment, income taxes, percentage-of-completion accounting for long-term contracts, self-insurance, pension and post retirement benefit plans, contingencies and share-based compensation.  We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.  Actual results could differ from those estimates.
	Principles of Consolidation
	We consolidate all wholly-owned subsidiaries, controlled joint ventures and variable interest entities where the Company has determined it is the primary beneficiary.  Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. All material intercompany accounts and transactions have been eliminated in consolidation.

	2.    Business Combinations and Dispositions
	We have acquired businesses we believe are important to our long-term strategy.  Results of operations for acquisitions are included in the accompanying Condensed Consolidated Statements of Operations from the date of acquisition.  The balances included in the Condensed Consolidated Balance Sheets related to recent acquisitions are based on preliminary information and are subject to change when final asset valuations are obtained and potential liabilities have been evaluated.  The purchase price is allocated to the net assets acquired based upon their estimated fair values at the date of acquisition.  During the nine months ended September 30, 2013, we acquired businesses for cash consideration of $7 million, net of cash acquired.
	During the nine months ended September 30, 2013, we completed the sale of our industrial screen business for proceeds totaling $135 million.  Proceeds consisted of $100 million in cash and a $35 million receivable.  Through our industrial screen operations, we delivered screen technologies used in numerous industries and, as a result, the screen business was not closely aligned with our goals as a leading provider of equipment and services used in the drilling, evaluation, completion, production and intervention of oil and natural gas wells.  In the nine months ended September 30, 2013 we recognized gains totaling $8 million resulting from the industrial screen transactions.  The major classes of assets sold in these transactions included $54 million in cash, $36 million of accounts receivable, $37 million of inventory, $92 million of other assets primarily comprised of property, plant and equipment, Other intangible assets and goodwill.  Liabilities of $69 million were also transferred in the sale, of which $60 million were current liabilities.
	On October 7, 2013 we closed the sale of our 38.5% equity interest in Borets International Limited ("Borets") for $400 million pursuant to an agreement executed August 21, 2013.  Borets is an electric submersible pump manufacturer that operates in Russia.  The $400 million in consideration consists of $370 million in cash and a three-year $30 million promissory note.  At closing we collected $325 million in cash and expect to collect the remaining cash consideration in November 2013.
	In 2012, we acquired a company that designs and produces well completion tools.  As part of the purchase consideration, we entered into a contingent consideration arrangement valued at approximately $9 million at September 30, 2013 that will be settled in early 2015.  This contingent consideration arrangement is dependent on the acquired company's 2014 results of operations.  This obligation will be marked to market through current earnings in each reporting period prior to settlement and the liability is valued using a Monte Carlo simulation and Level 3 inputs.

	3.    Accounts Receivable Factoring
	During the nine months ended September 30, 2013, we sold approximately $139 million of accounts receivable under our factoring program in Mexico. We received cash totaling $132 million and recognized a loss of approximately $2 million on the sales. These sales occurred in the first and third quarters of 2013.  During the three and nine months ended September 30, 2012, we sold approximately $96 million and $147 million, respectively, of accounts receivable under the program.  We received cash totaling $136 million and ultimately collected amounts that resulted in a loss of less than $1 million on these sales.
	Our factoring transactions qualify for sale accounting under the accounting standards and the proceeds are included in operating cash flows in our Condensed Consolidated Statements of Cash Flows.

Goodwill	'
	5.  Goodwill
	We perform an impairment test for goodwill and indefinite-lived intangible assets annually as of October 1, or more frequently if indicators of potential impairment exist.  Our goodwill impairment test involves a comparison of the fair value of each of our reporting units with its carrying amount. Fair value is estimated using discounted cash flows and a discount rate based on the weighted average cost of capital of the reporting unit. Our reporting units are based on our regional structure and consist of the United States, Canada, Latin America, Europe, Sub-Sahara Africa ("SSA"), Russia, Middle East/North Africa ("MENA") and Asia Pacific ("AP").
	The fair value of all our reporting units was in excess of their carrying value as of our October 1, 2012 annual impairment test. The fair value of our reporting unit in Latin America was closest to its carrying value and was 16% in excess of its carrying value at October 1, 2012.
	The changes in the carrying amount of goodwill by segment for the nine months ended September 30, 2013, were as follows:

	We maintain a $2.25 billion unsecured, revolving credit agreement (the "Credit Agreement") with JPMorgan Chase Bank, N.A., as administrative agent.  The Credit Agreement has a scheduled maturity date of July 13, 2016, and can be used for a combination of borrowings, support for our commercial paper program and issuances of letters of credit.  This agreement requires us to maintain a debt-to-capitalization ratio of less than 60%.  We are in compliance with this covenant at September 30, 2013. At September 30, 2013, our borrowings under our commercial paper program had a weighted average interest rate of 1.01% and there were $41 million in outstanding letters of credit under the Credit Agreement.
	On May 1, 2013, we entered into a $300 million, 364-day, term loan facility with a syndicate of banks.  The facility was fully drawn on May 1, 2013 and will mature on April 30, 2014.  The terms and conditions of the facility are substantially similar to our $2.25 billion revolving credit agreement.  The facility is used for general corporate purposes, including the repayment of other credit facility borrowings.
	We also have short-term borrowings with various domestic and international institutions pursuant to uncommitted facilities.  At September 30, 2013, we had $194 million in short-term borrowings under these arrangements with a weighted average interest rate of 5.05%.  In addition, we had $557 million of letters of credit under various uncommitted facilities and $265 million of performance bonds issued by financial sureties against an indemnification from us at September 30, 2013.
	The carrying value of our short-term borrowings approximates their fair value as of September 30, 2013.  The current portion of long-term debt at September 30, 2013 includes $250 million of 4.95% Senior Notes due October 2013 and other debt maturing in 2013 totaling $68 million.

	7.    Fair Value of Financial Instruments
	Financial Instruments Measured and Recognized at Fair Value
	We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability.  Our valuation techniques require inputs that we categorize using a three level hierarchy, from highest to lowest level of observable inputs.  Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices or other market data for similar assets and liabilities in active markets, or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based upon our own judgment and assumptions used to measure assets and liabilities at fair value. Classification of a financial asset or liability within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.  Other than the contingent consideration discussed in Note 2 and  our derivative instruments discussed in Note 8, we had no assets or liabilities measured and recognized at fair value on a recurring basis at September 30, 2013 and December 31, 2012.
	Fair Value of Other Financial Instruments
	Our other financial instruments include short-term borrowings and long-term debt.  The carrying value of our commercial paper and other short-term borrowings approximates their fair value due to the short-term duration of the associated interest rate periods.  These short-term borrowings are classified as Level 2 in the fair value hierarchy.
	The fair value of our long-term debt fluctuates with changes in applicable interest rates.  Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued.  The fair value of our long-term debt is a measure of its current value under present market conditions and is established based on observable inputs in non-active markets.  Our long-term debt is classified as Level 2 in the fair value hierarchy.
	The fair value and carrying value of our senior notes were as follows:

Derivative Instruments	'
	8.    Derivative Instruments
	We are exposed to market risk from changes in foreign currency and changes in interest rates.  From time to time, we may enter into derivative financial instrument transactions to manage or reduce our market risk.  We manage our debt portfolio to achieve an overall desired position of fixed and floating rates and we may employ interest rate swaps as a tool to achieve that goal.  The major risks from interest rate derivatives include changes in the interest rates affecting the fair value of such instruments, potential increases in interest expense due to market increases in floating interest rates and the creditworthiness of the counterparties in such transactions.  In light of events in the global credit markets and the potential impact of these events on the liquidity of the banking industry, we continue to monitor the creditworthiness of our counterparties, which are multinational commercial banks.
	The fair values of all our outstanding derivative instruments are determined using a model with Level 2 inputs including quoted market prices for contracts with similar terms and maturity dates.
	Fair Value Hedges
	From time to time we may use interest rate swaps to help mitigate exposures related to changes in the fair values of our debt.  Amounts paid or received upon termination of interest rate swaps accounted for as fair value hedges represent the fair value of the agreements at the time of termination and are recorded as an adjustment to the carrying value of the related debt.  These amounts are amortized as a reduction, in the case of gains, or as an increase, in the case of losses, of interest expense over the remaining term of the debt. As of September 30, 2013, we had net unamortized gains of $44 million associated with interest rate swap terminations.  These gains are being amortized over the remaining term of the originally hedged debt as a reduction in interest expense.
	Cash Flow Hedges
	We entered into interest rate derivative instruments to hedge projected exposures to interest rates in anticipation of a debt offering in 2008.  Those hedges were terminated at the time of the issuance of the debt, and the loss on these hedges is being amortized from accumulated other comprehensive income (loss) into interest expense over the remaining term of the debt.  As of September 30, 2013, we had net unamortized losses of $11 million associated with our cash flow hedge terminations.
	Other Derivative Instruments
	As of September 30, 2013, we had foreign currency forward contracts with notional amounts aggregating to $753 million. These contracts were entered into to hedge exposure to currency fluctuations in various foreign currencies.  The total estimated fair value of these contracts, and amounts receivable or owed associated with closed contracts, resulted in a net liability of approximately $11 million.  These derivative instruments were not designated as hedges and the changes in fair value of the contracts are recorded each period in other, net in the accompanying Condensed Consolidated Statements of Operations.
	We have cross-currency swaps between the U.S. dollar and Canadian dollar to hedge certain exposures to the Canadian dollar.  At September 30, 2013, we had notional amounts outstanding of $168 million.  The total estimated fair value of these contracts at September 30, 2013, resulted in a liability of $27 million. These derivative instruments were not designated as hedges and the changes in fair value of the contracts are recorded each period in other, net in the accompanying Condensed Consolidated Statements of Operations.
	The fair values of outstanding derivative instruments are summarized as follows:

	9.    Income Tax
	For the three and nine months ended September 30, 2013, we had a tax provision of $49 million and $74 million on income before tax of $80 million and $24 million.  Our effective tax rate for the three and nine months ended September 30, 2013 is 61% and 308%, respectively.  Our income before taxes for the nine months ended September 30, 2013 includes a $153 million charge for the potential settlement of the oil-for-food and Foreign Corrupt Practices Act matters with no tax benefit. Our tax provision for the three months ended September 30, 2013 includes discrete tax benefits primarily due to audit closures and tax planning activities, which decreased our effective tax rate for the period.  Our provision for the nine months ended September 30, 2013, in addition to items above, also includes discrete tax benefits due to the devaluation of the Venezuelan bolivar, return-to-accrual adjustments, decreases in reserves for uncertain tax positions due to statute of limitation expiration and the enactment of the American Taxpayer Relief Act, which decreased our effective tax rate for the period.
	For the three and nine months ended September 30, 2012, we had a tax provision of $86 million and $259 million on income before tax of $163 million and loss before tax of $377 million. Our effective tax rate for the three and nine months ended September 30, 2012 was 53% and (69)%, respectively.  Our loss before taxes for the nine months ended September 30, 2012 includes a $589 million charge for the impairment of goodwill, substantially all of which was non- deductible, a $204 million equity method impairment charge and a $100 million accrual for a loss contingency, both of which were fully non-deductible.
	We anticipate a possible reduction in the balance of uncertain tax positions between $60 million to $100 million in the next twelve months due to expiration of statutes of limitations, settlements and/or conclusions of tax examinations.

	Basic earnings per share for all periods presented equals net income divided by the weighted average number of our shares outstanding during the period.  Diluted earnings per share is computed by dividing net income by the weighted average number of our shares outstanding during the period, adjusted for the dilutive effect of our stock options, restricted shares,  performance units and warrants.
	The following table presents a reconciliation of basic and diluted weighted average of shares outstanding:

	During the nine months ended September 30, 2013, we also granted 4.1 million restricted share awards at a weighted average grant date fair value of $13.08 per share.  As of September 30, 2013, there was $74 million of unrecognized compensation related to our unvested restricted share grants. This cost is expected to be recognized over a weighted average period of two years.

Disputes, Litigation and Contingencies [Abstract]	'
Disputes, Litigation and Contingencies	'
	14.  Disputes, Litigation and Contingencies
	U.S. Government and Internal Investigations
	We are currently involved in government and internal investigations.
	The U.S. Department of Commerce, Bureau of Industry & Security, Office of Foreign Assets Control ("OFAC"), Department of Justice ("DOJ") and SEC have undertaken investigations of allegations of improper sales of products and services by the Company and its subsidiaries in certain sanctioned countries. We have cooperated fully with these investigations and we have retained legal counsel, reporting directly to our Audit Committee, to investigate these matters.
	In light of these investigations, the U.S. and foreign policy environment and the inherent uncertainties surrounding these countries, we decided in September 2007 to direct our foreign subsidiaries to discontinue doing business in countries that are subject to comprehensive U.S. economic and trade sanctions, specifically Cuba, Iran and Sudan, as well as Syria. Effective September 2007, we ceased entering into any new contracts in these countries and began an orderly discontinuation and winding down of our existing business in these sanctioned countries.
	Effective March 31, 2008, we substantially completed our winding down of business in these countries and conducted further withdrawal activities, pursuant to the licenses issued by OFAC, which have now ceased. Certain of our subsidiaries continue to conduct business in countries such as Myanmar, which was subject to more limited U.S. trading sanctions until 2012.
	We have been in negotiations with the government agencies to resolve the investigation into alleged violations of the trade sanctions laws for more than two years, and these negotiations have advanced significantly.  During the quarter ended June 30, 2012, the negotiations progressed to a point where we recognized a liability for a loss contingency that we believe is probable and for which a reasonable estimate can be made.  The Company estimates that the amount of this loss is $100 million and recognized a loss contingency equal to such amount in the quarter ended June 30, 2012.  We have reached agreements of terms and fine payments relating to the alleged violations of the trade sanctions laws with the DOJ and government agency representatives.  Final settlement will require definitive documentation, acceptance by supervising officials and judicial approval.  The proposed agreement contemplates total payments to government agencies of $100 million, the amount for which the Company recognized a loss contingency in the quarter ended June 30, 2012.  The settlement would also require an agreement under which criminal prosecution for the Company would be deferred for two years and plea agreements imposing potential criminal convictions on two of the Company's subsidiaries.
	Until 2003, we participated in the United Nations oil-for-food program governing sales of goods and services into Iraq. The DOJ and SEC have undertaken investigations of our participation in the oil-for-food program and have subpoenaed certain documents in connection with these investigations.  We have cooperated fully with these investigations. We have retained legal counsel, reporting to our Audit Committee, to investigate this matter. The DOJ and SEC have also investigated our compliance with the Foreign Corrupt Practices Act ("FCPA") and other laws worldwide. We have retained legal counsel, reporting to our Audit Committee, to investigate these matters and we are cooperating fully with the DOJ and SEC.  As part of our internal investigations, we have uncovered potential violations of U.S. law in connection with activities in several jurisdictions.
	We have been in frequent negotiations with the government agencies to resolve these matters. During the quarter ended June 30, 2013, negotiations related to the oil-for-food and FCPA matters progressed to a point where we recognized a liability for a loss contingency that we believe is probable and for which a reasonable estimate can be made.  The Company estimates that the amount of this loss is $153 million and recognized a loss contingency equal to such amount in the quarter ended June 30, 2013.  Since our last 10-Q filing, substantial progress in the negotiations was made, and these negotiations have recently concluded. These negotiations have resulted in agreements with representatives of the DOJ and the SEC enforcement staff relating to terms and total payments to be made to government agencies relating to the oil-for-food and FCPA matters subject in each case to final review and approval by the DOJ and SEC Commission as well as judicial approval.  The agreements would require total payments to government agencies equal to the $153 million loss contingency that the Company recognized in the quarter ended June 30, 2013.  The agreements would also include (1) an agreement under which criminal prosecution for the Company would be deferred for three years and a plea agreement would impose a criminal conviction on one of the Company's subsidiaries; (2) a requirement to retain, for a period of at least 18 months, an independent monitor responsible to assess the Company's compliance with the terms of the agreement so as to address and reduce the risk of recurrence of alleged misconduct, after which the Company would continue to evaluate its own compliance program and make periodic reports to the DOJ and SEC; and (3) a requirement to maintain agreed compliance monitoring and reporting systems.  If final settlement terms differ from the agreements we have reached with DOJ and SEC representatives or if necessary approvals are not ultimately obtained, we could become subject to injunctive relief, disgorgement, fines, penalties, sanctions or imposed modifications to business practices that could adversely affect our results of operations.
	The SEC and DOJ are also investigating the circumstances surrounding the material weakness in the Company's internal control over financial reporting for income taxes that was disclosed in a notification of late filing on Form 12b-25 filed on March 1, 2011 and in current reports on Form 8-K filed on February 21, 2012 and on July 24, 2012 and the subsequent restatements of our historical financial statements. We are cooperating fully with these investigations.  We are unable to predict the outcome of these matters due to the inherent uncertainties they present while investigations are pending, and we are unable to predict potential outcomes or estimate the range of potential loss contingencies, if any.  The government, generally, has a broad range of civil and criminal penalties available, for these types of matters, under applicable law and regulation, including injunctive relief, fines, penalties and modifications to business practices, some of which, if imposed on the Company, could be material to our business, financial condition or results of operations. In September 2013, we also received the final decision of the SIX Swiss Exchange Sanction Commission regarding its investigation for similar internal controls and restatement matters.  The decision resulted in a fine of $270,000 plus costs; we do not plan to appeal.
	Shareholder Litigation
	In 2010, three shareholder derivative actions were filed, purportedly on behalf of the Company, asserting breach of duty and other claims against certain current and former officers and directors of the Company related to the oil for food, FCPA and trade sanctions U.S. government investigations disclosed above and in our SEC filings since 2007.  Those shareholder derivative cases are pending in the Harris County, Texas, civil court and are captioned Neff v. Brady, et al., No. 201040764, Hess v. Duroc-Danner, et al., No. 201040765, and Rosner v. Brady, et al., No. 201047343.
	In March 2011, a purported shareholder class action captioned Dobina v. Weatherford International Ltd., et al., No. 1:11-cv-01646-LAK (SDNY), was filed in the U.S. District Court for the Southern District of New York, following the Company's announcement on March 1, 2011 of a material weakness in its internal controls over financial reporting for income taxes, and restatement of our historical financial statements.  The Dobina complaint alleged violation of the federal securities laws by the Company and certain current and former officers and directors.  Also in March 2011, a shareholder derivative action, Iron Workers Mid-South Pension Fund v. Duroc-Danner, et al., No. 201119822, was filed in Harris County, Texas, civil court purportedly on behalf of the Company against certain current and former officers and directors, alleging breaches of duty related to the material weakness and restatement announcements.  In February 2012, a second shareholder derivative action,  Wandel v. Duroc-Danner, et al., No. 1:12-cv-01305-LAK (SDNY), was filed in federal court in the Southern District of New York.  In March 2012, a second purported securities class action captioned Freedman v. Weatherford International Ltd., et al., No. 1:12-cv-02121-LAK (SDNY) was filed in the Southern District of New York against the Company, and certain current and former officers.  That case alleges violation of the federal securities laws related to the restatement of our historical financial statements announced on February 21, 2012, and later added claims related to the announcement of a subsequent restatement on July 24, 2012.
	We cannot predict the outcome of these cases including the amount of any possible loss.  If one or more negative outcomes were to occur relative to these cases, the aggregate impact to our financial condition could be material.
	Other Disputes
	A former Senior Vice President and General Counsel (the "Executive") left the Company in June 2009. The Executive had employment agreements with us that terminated on his departure. There is currently a dispute between the Executive and us as to the amount of compensation we are obligated to pay under these employment agreements based on the Executive's separation. This dispute has not resulted in a lawsuit being filed. It is our belief that an unfavorable outcome regarding this dispute is not probable, and as such, we have not accrued for $9 million of the Executive's claimed severance and other benefits.
	Additionally, we are aware of various disputes and potential claims and are a party in various litigation involving claims against us, some of which are covered by insurance. For claims, disputes and pending litigation in which we believe a negative outcome is probable and a loss can be reasonably estimated, we have recorded a liability for the expected loss. These liabilities are immaterial to our financial condition and results of operations. In addition we have certain claims, disputes and pending litigation in which we do not believe a negative outcome is probable or for which we can only estimate a range of liability.  If one or more negative outcomes were to occur relative to these matters, the aggregate impact to our financial condition could be material.

	In February 2013, the FASB issued new guidance intended to improve the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety from accumulated other comprehensive income to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This guidance became effective for us in our second quarter of 2013.  Please see Note 10 — Shareholders' Equity, which presents the reclassifications out of Accumulated Other Comprehensive Income.
	In July 2013, the FASB issued new guidance intended to clarify the presentation of unrecognized tax benefits. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carryforward, with certain exceptions.  The unrecognized tax benefit should be presented as a liability and should not be combined with deferred tax assets to the extent that: 1) the deferred tax asset is not available under the tax law of the applicable jurisdiction to settle additional income taxes resulting from disallowance of the tax position, or 2) the entity is not required to use the deferred tax asset under the tax law of the applicable jurisdiction and the entity does not intend to use the deferred tax asset to offset additional taxes that would result from disallowance of the position.  This guidance will be effective for us beginning with the first quarter of 2014 and may be adopted prospectively for all unrecognized tax benefits that exist at the effective date or retrospectively.  The adoption of this guidance is not expected to have a material impact on our financial position, results of operations or cash flows.

	Principles of Consolidation
	We consolidate all wholly-owned subsidiaries, controlled joint ventures and variable interest entities where the Company has determined it is the primary beneficiary.  Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. All material intercompany accounts and transactions have been eliminated in consolidation.

Goodwill [Abstract]	'
Goodwill Policy	'
	We perform an impairment test for goodwill and indefinite-lived intangible assets annually as of October 1, or more frequently if indicators of potential impairment exist.  Our goodwill impairment test involves a comparison of the fair value of each of our reporting units with its carrying amount. Fair value is estimated using discounted cash flows and a discount rate based on the weighted average cost of capital of the reporting unit. Our reporting units are based on our regional structure and consist of the United States, Canada, Latin America, Europe, Sub-Sahara Africa ("SSA"), Russia, Middle East/North Africa ("MENA") and Asia Pacific ("AP").
	The fair value of all our reporting units was in excess of their carrying value as of our October 1, 2012 annual impairment test. The fair value of our reporting unit in Latin America was closest to its carrying value and was 16% in excess of its carrying value at October 1, 2012.
