Significant Accounting Policies [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Principles of Consolidation

Our consolidated financial statements include the accounts of Boston Scientific Corporation and our wholly-owned subsidiaries, after the elimination of intercompany transactions. We assess the terms of our investment interests to determine if any of our investees meet the definition of a variable interest entity (VIE). For any VIEs, we perform an analysis to determine whether our variable interests give us a controlling financial interest in a VIE. The analysis identifies the primary beneficiary of a VIE as the enterprise that has both 1) the power to direct activities of a VIE that most significantly impact the entity’s economic performance and 2) the obligation to absorb losses of the entity or the right to receive benefits from the entity. Based on our assessments under the applicable guidance, we did not have significant interests in any VIEs and therefore did not consolidate any VIEs during the years ended December 31, 2012, 2011, and 2010.

On January 3, 2011, we closed the sale of our Neurovascular business to Stryker Corporation. We are providing transitional services to Stryker through a transition services agreement. We are also manufacturing and supplying products to Stryker through a supply agreement. These transition services and supply agreements are expected to end in 2013. Due to our continuing involvement in the operations of the Neurovascular business, the divestiture does not meet the criteria for presentation as a discontinued operation and, therefore, the results of the Neurovascular business are included in our results of operations for all periods presented. Refer to Note C – Divestitures and Assets Held for Sale for a description of this business divestiture.

Basis of Presentation

The accompanying consolidated financial statements of Boston Scientific Corporation have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and with the instructions to Form 10-K and Article 10 of Regulation S-X.

Reclassification

We have reclassified certain prior year amounts to conform to the current year’s presentation. See Note O – Segment Reporting for further details.

Subsequent Events, Policy [Policy Text Block]

Subsequent Events

We evaluate events occurring after the date of our accompanying consolidated balance sheets for potential recognition or disclosure in our financial statements. We did not identify any material subsequent events requiring adjustment to our accompanying consolidated financial statements (recognized subsequent events). Those items requiring disclosure (unrecognized subsequent events) in the financial statements have been disclosed accordingly. Refer to Note K– Commitments and Contingencies, Note L - Stockholders' Equity and Note H - Restructuring-Related Activities for more information.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

We record cash and cash equivalents in our consolidated balance sheets at cost, which approximates fair value. Our policy is to invest excess cash in short-term marketable securities earning a market rate of interest without assuming undue risk to principal, and we limit our direct exposure to securities in any one industry or issuer. We consider all highly liquid investments purchased with a remaining maturity of three months or less at the time of acquisition to be cash equivalents.

We record available-for-sale investments at fair value and exclude unrealized gains and temporary losses on available-for-sale securities from earnings, reporting such gains and losses, net of tax, as a separate component of stockholders’ equity, until realized. We compute realized gains and losses on sales of available-for-sale securities based on the average cost method, adjusted for any other-than-temporary declines in fair value. We held no available-for-sale securities during 2012, 2011 and 2010.

Concentration Risk Disclosure [Text Block]

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, derivative financial instrument contracts and accounts and notes receivable. Our investment policy limits exposure to concentrations of credit risk and changes in market conditions. Counterparties to financial instruments expose us to credit-related losses in the event of nonperformance. We transact our financial instruments with a diversified group of major financial institutions with investment grade credit ratings and actively monitor their credit ratings and our outstanding positions to limit our credit exposure. We provide credit, in the normal course of business, to hospitals, healthcare agencies, clinics, doctors' offices and other private and governmental institutions and generally do not require collateral. We record our accounts receivable in our consolidated balance sheets at net realizable value. We perform on-going credit evaluations of our customers and maintain allowances for potential credit losses, based on historical information and management's best estimates. Amounts determined to be uncollectible are written off against this reserve. We recorded write-offs of uncollectible accounts receivable of $7 million in 2012, $13 million in 2011, and $15 million in 2010. We are not dependent on any single institution and no single customer accounted for more than ten percent of our net sales in 2012, 2011, or 2010 or accounts receivable at December 31, 2012 or 2011; however, large group purchasing organizations, hospital networks and other buying groups have become increasingly important to our business and represent a substantial portion of our U.S. net sales.

We closely monitor outstanding receivables for potential collection risks, including those that may arise from economic conditions, in both the U.S. and international economies. Our European sales to government-owned or supported customers in Southern Europe, specifically Greece, Italy, Spain and Portugal are subject to an increased number of days outstanding above historical levels prior to payment due to the fiscal and debt crises in these countries. Historically, receivable balances with certain publicly-owned hospitals in these countries accumulate over a period of time and are then subsequently settled as large lump sum payments. While we believe our allowance for doubtful accounts in these countries is adequate as of December 31, 2012, if significant changes were to occur in the payment practices of these European governments or if government funding becomes unavailable, we may not be able to collect on receivables due to us from these customers and our write-offs of uncollectible amounts may increase. As of December 31, 2012, our net receivables in these countries greater than 180 days past due totaled $51 million, of which $17 million were past due greater than 365 days.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

We generate revenue primarily from the sale of single-use medical devices, and present revenue net of sales taxes in our consolidated statements of operations. We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors. We consider revenue to be realized or realizable and earned when all of the following criteria are met: persuasive evidence of a sales arrangement exists; delivery has occurred or services have been rendered; the price is fixed or determinable; and collectibility is reasonably assured. Revenue is recognized upon passage of title and risk of loss to customers, unless a consignment arrangement exists or we are required to provide additional services, and provided we can form an estimate for sales returns. We recognize revenue from consignment arrangements based on product usage, or implant, which indicates that the sale is complete. Many of our Cardiac Rhythm Management (CRM) product offerings combine the sale of a device with our LATITUDE^® Patient Management System, which represents a future service obligation. For revenue arrangements with multiple deliverables, where the sale of a device is combined with a future service obligation, we defer revenue on the undelivered element and recognize this revenue over the related service period. We do not have vendor specific objective evidence of selling price available related to our future service obligations; therefore, we determine our estimates of selling price using third party evidence when available; otherwise, we use our best estimate of selling price. We allocate arrangement consideration using the relative selling price method.

We generally allow our customers to return defective, damaged and, in certain cases, expired products for credit. We base our estimate for sales returns upon historical trends and record the amount as a reduction to revenue when we sell the initial product. In addition, we may allow customers to return previously purchased products for next-generation product offerings. For these transactions, we defer recognition of revenue on the sale of the earlier generation product based upon an estimate of the amount of product to be returned when the next-generation products are shipped to the customer.

We also offer sales rebates and discounts to certain customers. We treat sales rebates and discounts as a reduction of revenue and classify the corresponding liability as current. We estimate rebates for products where there is sufficient historical information available to predict the volume of expected future rebates. If we are unable to estimate the expected rebates reasonably, we record a liability for the maximum rebate percentage offered. We have entered certain agreements with group purchasing organizations to sell our products to participating hospitals at negotiated prices. We recognize revenue from these agreements following the same revenue recognition criteria discussed above.

Product Warranty Disclosure [Text Block]

Warranty Obligations

We offer warranties on certain of our product offerings. The majority of our warranty liability relates to implantable devices offered by our CRM business, which include defibrillator and pacemaker systems. Our CRM products come with a standard limited warranty covering the replacement of these devices. We offer a full warranty for a portion of the period post-implant, and a partial warranty for a period of time thereafter. We estimate the costs that we may incur under our warranty programs based on the number of units sold, historical and anticipated rates of warranty claims and cost per claim, and record a liability equal to these estimated costs as cost of products sold at the time the product sale occurs. We assess the adequacy of our recorded warranty liabilities on a quarterly basis and adjust these amounts as necessary.

Changes in our product warranty accrual during 2012, 2011, and 2010 consisted of the following (in millions):

	Year Ended December 31,
	2012			2011			2010
Beginning balance	$	30		$	43		$	55
Provision	8			9			15
Settlements/ reversals	(12		)	(22		)	(27		)
Ending balance	$	26		$	30		$	43

Inventory, Policy [Policy Text Block]

Inventories

We state inventories at the lower of first-in, first-out cost or market. We base our provisions for excess, expired and obsolete inventory primarily on our estimates of forecasted net sales. A significant change in the timing or level of demand for our products as compared to forecasted amounts may result in recording additional provisions for excess, expired and obsolete inventory in the future. Further, the industry in which we participate is characterized by rapid product development and frequent new product introductions. Uncertain timing of next-generation product approvals, variability in product launch strategies, product recalls and variation in product utilization all affect our estimates related to excess, expired and obsolete inventory. Approximately 40 percent of our finished goods inventory as of December 31, 2012 and 2011 was at customer locations pursuant to consignment arrangements.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment

We state property, plant, equipment, and leasehold improvements at historical cost. We charge expenditures for maintenance and repairs to expense and capitalize additions and improvements that extend the life of the underlying asset. We provide for depreciation using the straight-line method at rates that approximate the estimated useful lives of the assets. We depreciate buildings and improvements over a 20 to 40 year life; equipment, furniture and fixtures over a three to ten year life; and leasehold improvements over the shorter of the useful life of the improvement or the term of the related lease. Depreciation expense was $288 million in 2012, $296 million in 2011, and $303 million in 2010.

Business Combinations Policy [Policy Text Block]

Valuation of Business Combinations

We allocate the amounts we pay for each acquisition to the assets we acquire and liabilities we assume based on their fair values at the dates of acquisition, including identifiable intangible assets and purchased research and development which either arise from a contractual or legal right or are separable from goodwill. We base the fair value of identifiable intangible assets acquired in a business combination, including purchased research and development, on detailed valuations that use information and assumptions provided by management, which consider management’s best estimates of inputs and assumptions that a market participant would use. We allocate any excess purchase price over the fair value of the net tangible and identifiable intangible assets acquired to goodwill. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, cash flows, discount rates, estimated useful lives and probabilities surrounding the achievement of clinical, regulatory or revenue-based milestones could result in different purchase price allocations and amortization expense in current and future periods. Transaction costs associated with these acquisitions are expensed as incurred through selling, general and administrative costs.

In those circumstances where an acquisition involves a contingent consideration arrangement, we recognize a liability equal to the fair value of the contingent payments we expect to make as of the acquisition date. We re-measure this liability each reporting period and record changes in the fair value through a separate line item within our consolidated statements of operations. Increases or decreases in the fair value of the contingent consideration liability can result from changes in discount periods and rates, as well as changes in the timing and amount of revenue estimates or in the timing or likelihood of achieving regulatory, revenue or commercialization-based milestones.

In Process Research and Development, Policy [Policy Text Block]

Indefinite-lived Intangibles, including In-Process Research and Development

Our indefinite-lived intangible assets that are not subject to amortization primarily include acquired stent and balloon technology, which is foundational to our continuing operations within the Cardiovascular market and other markets within interventional medicine, and purchased research and development intangible assets acquired in a business combination. Our purchased research and development represents intangible assets acquired in a business combination that are used in research and development activities but have not yet reached technological feasibility, regardless of whether they have alternative future use. The primary basis for determining the technological feasibility or completion of these projects is obtaining regulatory approval to market the underlying products in an applicable geographic region. We classify purchased research and development acquired in a business combination as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts. Upon completion of the associated research and development efforts, we will determine the useful life of the technology and begin amortizing the assets to reflect their use over their remaining lives. Upon permanent abandonment, we would write-off the remaining carrying amount of the associated purchased research and development intangible asset. We test our indefinite-lived intangible assets at least annually for impairment and reassess their classification as indefinite-lived assets. We assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that our indefinite-lived intangible assets are impaired. If we conclude that it is more likely than not that the asset is impaired, we then determine the fair value of the intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying value in accordance with ASC Topic 350, Intangibles-Goodwill and Other. If the carrying value exceeds the fair value of the indefinite-lived intangible asset, we write the carrying value down to the fair value.

We use the income approach to determine the fair values of our purchased research and development. This approach calculates fair value by estimating the after-tax cash flows attributable to an in-process project over its useful life and then discounting these after-tax cash flows back to a present value. We base our revenue assumptions on estimates of relevant market sizes, expected market growth rates, expected trends in technology and expected levels of market share. In arriving at the value of the in-process projects, we consider, among other factors: the in-process projects’ stage of completion; the complexity of the work completed as of the acquisition date; the costs already incurred; the projected costs to complete; the contribution of other acquired assets; the expected regulatory path and introduction dates by region; and the estimated useful life of the technology. We apply a market-participant risk-adjusted discount rate to arrive at a present value as of the date of acquisition. We believe that the estimated in-process research and development amounts so determined represent the fair value and do not exceed the amount a third party would pay for the projects. However, if the projects are not successful or completed in a timely manner, we may not realize the financial benefits expected for these projects or for the acquisition as a whole.

We test our purchased research and development intangible assets acquired in a business combination for impairment at least annually during the third quarter, and more frequently if events or changes in circumstances indicate that the assets may be impaired.

For asset purchases outside of business combinations, we expense any purchased research and development assets as of the acquisition date.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Amortization and Impairment of Intangible Assets

We record intangible assets at historical cost and amortize them over their estimated useful lives. We use a straight-line method of amortization, unless a method that better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise used up can be reliably determined. The approximate useful lives for amortization of our intangible assets is as follows: patents and licenses, two to 20 years; definite-lived technology-related, five to 25 years; customer relationships, five to 25 years; other intangible assets, various.

We review intangible assets subject to amortization quarterly to determine if any adverse conditions exist or a change in circumstances has occurred that would indicate impairment or a change in the remaining useful life. Conditions that may indicate impairment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset, a product recall, or an adverse action or assessment by a regulator. If an impairment indicator exists, we test the intangible asset for recoverability. For purposes of the recoverability test, we group our amortizable intangible assets with other assets and liabilities at the lowest level of identifiable cash flows if the intangible asset does not generate cash flows independent of other assets and liabilities. If the carrying value of the intangible asset (asset group) exceeds the undiscounted cash flows expected to result from the use and eventual disposition of the intangible asset (asset group), we will write the carrying value down to the fair value in the period identified.

We generally calculate fair value of our intangible assets as the present value of estimated future cash flows we expect to generate from the asset using a risk-adjusted discount rate. In determining our estimated future cash flows associated with our intangible assets, we use estimates and assumptions about future revenue contributions, cost structures and remaining useful lives of the asset (asset group). The use of alternative assumptions, including estimated cash flows, discount rates, and alternative estimated remaining useful lives could result in different calculations of impairment. However, we believe our assumptions and estimates are reasonable and represent our best estimates. See Note D - Goodwill and Other Intangible Assets for more information related to impairments of intangible assets during 2012, 2011, and 2010.

For patents developed internally, we capitalize costs incurred to obtain patents, including attorney fees, registration fees, consulting fees, and other expenditures directly related to securing the patent.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill Valuation

We allocate any excess purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination to goodwill. We test our April 1 goodwill balances during the second quarter of each year for impairment, or more frequently if indicators are present or changes in circumstances suggest that impairment may exist. In performing the assessment, we utilize the two-step approach prescribed under ASC Topic 350, Intangibles-Goodwill and Other. The first step requires a comparison of the carrying value of the reporting units, as defined, to the fair value of these units. We assess goodwill for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment, referred to as a component. We determine our reporting units by first identifying our operating segments, and then assess whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. We aggregate components within an operating segment that have similar economic characteristics. For our 2012 impairment assessments, we identified six reporting units within the U.S., including our CRM, Neuromodulation, Endoscopy, Urology/Women's Health, Electrophysiology, and Cardiovascular (consisting of Interventional Cardiology and Peripheral Interventions) franchises, which in aggregate make up the U.S. reportable segment. In addition, we identified four international reporting units, including EMEA, Japan, Asia Pacific and the Americas. When allocating goodwill from business combinations to our reporting units, we assign goodwill to the reporting units that we expect to benefit from the respective business combination at the time of acquisition. In addition, for purposes of performing our goodwill impairment tests, assets and liabilities, including corporate assets, which relate to a reporting unit’s operations and would be considered in determining its fair value, are allocated to the individual reporting units. We allocate assets and liabilities not directly related to a specific reporting unit, but from which the reporting unit benefits, based primarily on the respective revenue contribution of each reporting unit.

During 2012, 2011, and 2010, we used only the income approach, specifically the discounted cash flow (DCF) method, to derive the fair value of each of our reporting units in preparing our goodwill impairment assessment. This approach calculates fair value by estimating the after-tax cash flows attributable to a reporting unit and then discounting these after-tax cash flows to a present value using a risk-adjusted discount rate. We selected this method as being the most meaningful in preparing our goodwill assessments because we believe the income approach most appropriately measures our income producing assets. We have considered using the market approach and cost approach but concluded they are not appropriate in valuing our reporting units given the lack of relevant market comparisons available for application of the market approach and the inability to replicate the value of the specific technology-based assets within our reporting units for application of the cost approach. Therefore, we believe that the income approach represents the most appropriate valuation technique for which sufficient data is available to determine the fair value of our reporting units.

In applying the income approach to our accounting for goodwill, we make assumptions about the amount and timing of future expected cash flows, terminal value growth rates and appropriate discount rates. The amount and timing of future cash flows within our DCF analysis is based on our most recent operational budgets, long range strategic plans and other estimates. The terminal value growth rate is used to calculate the value of cash flows beyond the last projected period in our DCF analysis and reflects our best estimates for stable, perpetual growth of our reporting units. We use estimates of market-participant risk-adjusted weighted-average costs of capital (WACC) as a basis for determining the discount rates to apply to our reporting units’ future expected cash flows.

If the carrying value of a reporting unit exceeds its fair value, we then perform the second step of the goodwill impairment test to measure the amount of impairment loss, if any. The second step of the goodwill impairment test compares the estimated fair value of a reporting unit’s goodwill to its carrying value. If we were unable to complete the second step of the test prior to the issuance of our financial statements and an impairment loss was probable and could be reasonably estimated, we would recognize our best estimate of the loss in our current period financial statements and disclose that the amount is an estimate. We would then recognize any adjustment to that estimate in subsequent reporting periods, once we have finalized the second step of the impairment test. See Note D - Goodwill and Other Intangible Assets for discussion of our goodwill impairment charges.

Equity and Cost Method Investments, Policy [Policy Text Block]

Investments in Publicly Traded and Privately Held Entities

We account for our publicly traded investments as available-for-sale securities based on the quoted market price at the end of the reporting period. We compute realized gains and losses on sales of available-for-sale securities based on the average cost method, adjusted for any other-than-temporary declines in fair value. We account for our investments in privately held entities, for which fair value is not readily determinable, in accordance with ASC Topic 323, Investments – Equity Method and Joint Ventures.

We account for investments in entities over which we have the ability to exercise significant influence under the equity method if we hold 50 percent or less of the voting stock and the entity is not a VIE in which we are the primary beneficiary. We record these investments initially at cost, and adjust the carrying amount to reflect our share of the earnings or losses of the investee, including all adjustments similar to those made in preparing consolidated financial statements. The book value of investments that we accounted for under the equity method of accounting was $16 million as of December 31, 2012 and $7 million as of December 31, 2011. We account for investments in entities in which we have less than a 20 percent ownership interest under the cost method of accounting if we do not have the ability to exercise significant influence over the investee. The aggregate carrying amount of our cost method investments was $13 million as of December 31, 2012 and $16 million as of December 31, 2011. In addition, we had notes receivable from certain companies of $5 million as of December 31, 2012 and $44 million as of December 31, 2011.

Each reporting period, we evaluate our investments to determine if there are any events or circumstances that are likely to have a significant adverse effect on the fair value of the investment. Examples of such impairment indicators include, but are not limited to: a significant deterioration in earnings performance; recent financing rounds at reduced valuations; a significant adverse change in the regulatory, economic or technological environment of an investee; or a significant doubt about an investee’s ability to continue as a going concern. If we identify an impairment indicator, we will estimate the fair value of the investment and compare it to its carrying value. Our estimation of fair value considers all available financial information related to the investee, including valuations based on recent third-party equity investments in the investee. If the fair value of the investment is less than its carrying value, the investment is impaired and we make a determination as to whether the impairment is other-than-temporary. We deem an impairment to be other-than-temporary unless we have the ability and intent to hold an investment for a period sufficient for a market recovery up to the carrying value of the investment. Further, evidence must indicate that the carrying value of the investment is recoverable within a reasonable period. For other-than-temporary impairments, we recognize an impairment loss equal to the difference between an investment’s carrying value and its fair value. Impairment losses on our investments are included in other, net in our consolidated statements of operations.

Income Tax, Policy [Policy Text Block]

Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, we determine deferred tax assets and liabilities based on differences between the financial reporting and tax bases of our assets and liabilities. We measure deferred tax assets and liabilities using the enacted tax rates and laws that will be in effect when we expect the differences to reverse. We reduce our deferred tax assets by a valuation allowance if, based upon the weight of available evidence, it is more likely than not that we will not realize some portion or all of the deferred tax assets. We consider relevant evidence, both positive and negative, to determine the need for a valuation allowance. Information evaluated includes our financial position and results of operations for the current and preceding years, the availability of deferred tax liabilities and tax carrybacks, as well as an evaluation of currently available information about future years.

We do not provide income taxes on unremitted earnings of our foreign subsidiaries where we have indefinitely reinvested such earnings in our foreign operations. It is not practical to estimate the amount of income taxes payable on the earnings that are indefinitely reinvested in foreign operations. Unremitted earnings of our foreign subsidiaries that we have indefinitely reinvested in foreign operations are $11.041 billion as of December 31, 2012 and $10.346 billion as of December 31, 2011.

We provide for potential amounts due in various tax jurisdictions. In the ordinary course of conducting business in multiple countries and tax jurisdictions, there are many transactions and calculations where the ultimate tax outcome is uncertain. Judgment is required in determining our worldwide income tax provision. In our opinion, we have made adequate provisions for income taxes for all years subject to audit. Although we believe our estimates are reasonable, the final outcome of open tax matters may be different from that which we have reflected in our historical income tax provisions and accruals. Such differences could have a material impact on our income tax provision and operating results. See Note J - Income Taxes for further information and discussion of our income tax provision and balances.

Legal Costs, Policy [Policy Text Block]

Legal and Product Liability Costs

We are involved in various legal and regulatory proceedings, including intellectual property, breach of contract, securities litigation and product liability suits. In some cases, the claimants seek damages, as well as other relief, which, if granted, could require significant expenditures or impact our ability to sell our products. We are also the subject of certain governmental investigations, which could result in substantial fines, penalties, and administrative remedies. We maintain an insurance policy providing limited coverage against securities claims, and we are substantially self-insured with respect to product liability claims and fully self-insured with respect to intellectual property infringement claims. We generally record losses for claims in excess of the limits of purchased insurance in earnings at the time and to the extent they are probable and estimable. We accrue anticipated costs of settlement, damages, losses for general product liability claims and, under certain conditions, costs of defense, based on historical experience or to the extent specific losses are probable and estimable. Otherwise, we expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range. We analyze litigation settlements to identify each element of the arrangement. We allocate arrangement consideration to patent licenses received based on estimates of fair value, and capitalize these amounts as assets if the license will provide an on-going future benefit. See Note K - Commitments and Contingencies for discussion of our individual material legal proceedings.

Costs Associated with Exit or Disposal Activities or Restructurings, Policy

Costs Associated with Exit Activities

We record employee termination costs in accordance with ASC Topic 712, Compensation - Nonretirement and Postemployment Benefits, if we pay the benefits as part of an on-going benefit arrangement, which includes benefits provided as part of our domestic severance policy or that we provide in accordance with international statutory requirements. We accrue employee termination costs associated with an on-going benefit arrangement if the obligation is attributable to prior services rendered, the rights to the benefits have vested, the payment is probable and we can reasonably estimate the liability. We account for employee termination benefits that represent a one-time benefit in accordance with ASC Topic 420, Exit or Disposal Cost Obligations. We record such costs into expense over the employee’s future service period, if any. In addition, in conjunction with an exit activity, we may offer voluntary termination benefits to employees. These benefits are recorded when the employee accepts the termination benefits and the amount can be reasonably estimated. Other costs associated with exit activities may include contract termination costs, including costs related to leased facilities to be abandoned or subleased, and impairments of long-lived assets, and are expensed in accordance with ASC Topic 420 and ASC Topic 360, Property, Plant, and Equipment.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Translation of Foreign Currency

We translate all assets and liabilities of foreign subsidiaries from local currency into U.S. dollars using the year-end exchange rate, and translate revenues and expenses at the average exchange rates in effect during the year. We show the net effect of these translation adjustments in our consolidated financial statements as a component of accumulated other comprehensive loss. For any significant foreign subsidiaries located in highly inflationary economies, we would re-measure their financial statements as if the functional currency were the U.S. dollar. We did not record any highly inflationary economy translation adjustments in 2012, 2011 or 2010.

Foreign currency transaction gains and losses are included in other, net in our consolidated statements of operations, net of losses and gains from any related derivative financial instruments. We recognized net foreign currency transaction losses of $18 million in 2012, $12 million in 2011, and $9 million in 2010.

Derivatives, Policy [Policy Text Block]

Financial Instruments

We recognize all derivative financial instruments in our consolidated financial statements at fair value in accordance with ASC Topic 815, Derivatives and Hedging, and we present assets and liabilities associated with our derivative financial instruments on a gross basis in our financial statements. In accordance with Topic 815, for those derivative instruments that are designated and qualify as hedging instruments, the hedging instrument must be designated, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. The accounting for changes in the fair value (i.e. gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. Our derivative instruments do not subject our earnings or cash flows to material risk, as gains and losses on these derivatives generally offset losses and gains on the item being hedged. We do not enter into derivative transactions for speculative purposes and we do not have any non-derivative instruments that are designated as hedging instruments pursuant to Topic 815. Refer to Note E – Fair Value Measurements for more information on our derivative instruments.

Shipping and Handling Cost, Policy [Policy Text Block]

Shipping and Handling Costs

We generally do not bill customers for shipping and handling of our products. Shipping and handling costs of $105 million in 2012, $100 million in 2011, and $88 million in 2010 are included in selling, general and administrative expenses in the accompanying consolidated statements of operations.

Research and Development Expense, Policy [Policy Text Block]

Research and Development

We expense research and development costs, including new product development programs, regulatory compliance and clinical research as incurred. Refer to Purchased Research and Development for our policy regarding in-process research and development acquired in connection with our business combinations and asset purchases.

Pension and Other Postretirement Plans, Policy [Policy Text Block]

Employee Retirement Plans

In connection with our 2006 acquisition of Guidant Corporation, we sponsor the Guidant Retirement Plan, a frozen noncontributory defined benefit plan covering a select group of current and former employees. The funding policy for the plan is consistent with U.S. employee benefit and tax-funding regulations. Plan assets, which are maintained in a trust, consist primarily of equity and fixed-income instruments. Further, we sponsor the Guidant Supplemental Retirement Plan, a frozen, nonqualified defined benefit plan for certain former officers and employees of Guidant. The Guidant Supplemental Retirement Plan was funded through a Rabbi Trust that contains segregated company assets used to pay the benefit obligations related to the plan. In addition, certain current and former employees of Guidant are eligible to receive a portion of their healthcare retirement benefits under a frozen defined benefit plan.

In addition, we maintain an Executive Retirement Plan, a defined benefit plan covering executive officers and division presidents. Participants may retire with unreduced benefits once retirement conditions have been satisfied. We also maintain retirement plans covering certain international employees.

We use a December 31 measurement date for these plans and record the underfunded portion as a liability, recognizing changes in the funded status through other comprehensive income.

Earnings Per Share, Policy [Policy Text Block]

Net Income (Loss) per Common Share

We base net income (loss) per common share upon the weighted-average number of common shares and common stock equivalents outstanding during each year. Potential common stock equivalents are determined using the treasury stock method. We exclude stock options whose effect would be anti-dilutive from the calculation.
