| Fair Value Measurements And Financial Instruments     | FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTSThe fair value measurement accounting standard, codified in ASC Topic 820, Fair Value Measurement (ASC Topic 820), provides a framework for measuring fair value and defines fair value as the price that would be received to sell an asset or paid to transfer a liability. Fair value is a market-based measurement that should be determined using assumptions that market participants would use in pricing an asset or liability. The standard establishes a valuation hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on independent market data sources. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available. The valuation hierarchy is composed of three categories. The categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.The categories within the valuation hierarchy are described as follows:•Level 1 – Inputs to the fair value measurement are quoted prices in active markets for identical assets or liabilities.•Level 2 – Inputs to the fair value measurement include quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.•Level 3 – Inputs to the fair value measurement are unobservable inputs or valuation techniques.Assets and Liabilities that are Measured at Fair Value on a Recurring BasisThe fair value measurement standard applies to certain financial assets and liabilities that are measured at fair value on a recurring basis (each reporting period). These financial assets and liabilities include money-market securities, trading marketable securities, available-for-sale marketable securities and derivative instruments. The Company continues to record these items at fair value on a recurring basis and the fair value measurements are applied using ASC Topic 820. The Company does not have any material nonfinancial assets or liabilities that are measured at fair value on a recurring basis. A summary of the valuation methodologies used for the respective financial assets and liabilities measured at fair value on a recurring basis is as follows:Money-Market Securities: The Company’s money-market securities include funds that are traded in active markets and are recorded at fair value based upon the quoted market prices. The Company classifies these securities as level 1.Trading Securities: The Company’s trading securities include publicly-traded mutual funds that are traded in active markets and are recorded at fair value based upon quoted market prices of the net asset values of the funds. The Company classifies these securities as level 1.Available-For-Sale Securities: The Company’s available-for-sale securities include publicly-traded equity securities that are traded in active markets and are recorded at fair value based upon the closing stock prices. The Company classifies these securities as level 1. The following table summarizes the components of the balance of the Company’s available-for-sale securities at September 29, 2012 and December 31, 2011 (in millions): September 29, 2012 December 31, 2011Adjusted cost$9 $9Gross unrealized gains33 30Fair value$42 $39Derivative Instruments: The Company’s derivative instruments consist of foreign currency exchange contracts and interest rate swap contracts. The Company classifies these instruments as level 2 as the fair value is determined using inputs other than observable quoted market prices. These inputs include spot and forward foreign currency exchange rates and interest rates that the Company obtains from standard market data providers. The fair value of the Company’s outstanding foreign currency exchange contracts was not material at September 29, 2012 or December 31, 2011.A summary of financial assets measured at fair value on a recurring basis at September 29, 2012 and December 31, 2011 is as follows (in millions): Balance SheetClassificationSeptember 29, 2012 Quoted PricesIn ActiveMarkets(Level 1) SignificantOtherObservableInputs(Level 2) SignificantUnobservableInputs(Level 3)Assets        Money-market securitiesCash and cash equivalents$866 $866 $— $—Available-for-sale securitiesOther current assets42 42 — —Trading securitiesOther assets228 228 — —Total assets $1,136 $1,136 $— $— Balance SheetClassificationDecember 31, 2011 Quoted PricesIn ActiveMarkets(Level 1) SignificantOtherObservableInputs(Level 2) SignificantUnobservableInputs(Level 3)Assets        Money-market securitiesCash and cash equivalents$745 $745 $— $—Available-for-sale securitiesOther current assets39 39 — —Trading securitiesOther assets205 205 — —Interest rate swapOther assets18 — 18 —Total assets $1,007 $989 $18 $—Assets and Liabilities that are Measured at Fair Value on a Nonrecurring BasisThe fair value measurement standard also applies to certain nonfinancial assets and liabilities that are measured at fair value on a nonrecurring basis. A summary of the valuation methodologies used for the respective nonfinancial assets and liabilities measured at fair value on a nonrecurring basis is as follows:Long-Lived Assets: The Company reviews the carrying amount of its long-lived assets other than goodwill and indefinite-lived intangible assets for potential impairment whenever events or changes in circumstance include a significant decrease in market price, a significant adverse change in the extent or manner in which an asset is being used or a significant adverse change in the legal or business climate. The Company measures the fair value of its long-lived assets, such as its definite-lived intangible assets and property, plant and equipment using independent appraisals, market models and discounted cash flow models. A discounted cash flow model requires inputs to a present value cash flow calculation such as a risk-adjusted discount rate, terminal values, operating budgets, long-term strategic plans and remaining useful lives of the asset or asset group. If the carrying value of the Company’s long-lived assets (excluding goodwill and indefinite-lived intangible assets) exceeds the related undiscounted future cash flows, the carrying value is written down to the fair value in the period identified.During the third quarter of 2012, the Company determined that certain purchased technology intangible assets in the Company's NMD business were considered impaired as their future expected undiscounted cash flows did not exceed the carrying value of the related assets. As a result, the Company recognized a $23 million impairment charge to write-down the intangible assets to their estimated fair value of $3 million as of September 29, 2012. The fair value measurements of these intangible assets are considered Level 3 in the fair value hierarchy due to the use of unobservable inputs, specifically the discounted cash flows income approach method, to measure fair value. During the second quarter of 2012, the Company determined that certain purchased technology intangible assets in the Company's AF and CV businesses were considered impaired as their future expected undiscounted cash flows did not exceed the carrying value of the related assets. As a result, the Company recognized a $5 million impairment charge to write-down the intangible assets to their estimated fair value of $4 million as of June 30, 2012. The fair value measurements of these intangible assets are considered Level 3 in the fair value hierarchy due to the use of unobservable inputs, specifically the discounted cash flows income approach method, to measure fair value. During the second quarter of 2011, the Company initiated restructuring actions resulting in the planned future closure of its CRM manufacturing facility in Sweden, resulting in the recognition of a $12 million  impairment charge to write-down the facility to its estimated fair value of $13 million. The fair value measurement of the facility is considered Level 2 in the fair value hierarchy due to the use of observable inputs, specifically comparable third party sale prices for similar facilities. During the fourth quarter of 2011, the Company recognized $52 million of intangible asset impairments primarily associated with customer relationship intangible assets. Due to the changing dynamics of the U.S. healthcare market, these intangible assets were determined to have no future discrete cash flows and were fully impaired. Cost Method Investments: The Company also holds investments in equity securities that are accounted for as cost method investments, which are classified as other assets and measured at fair value on a nonrecurring basis. The carrying value of these investments approximated $144 million and $128 million at September 29, 2012 and December 31, 2011, respectively. The fair value of the Company’s cost method investments is not estimated if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of these investments. When measured on a nonrecurring basis, the Company’s cost method investments are considered Level 3 in the fair value hierarchy due to the use of unobservable inputs to measure fair value.Fair Value Measurements of Other Financial InstrumentsThe aggregate fair value of the Company’s fixed-rate senior notes at September 29, 2012 (measured using quoted prices in active markets) was $2,563 million compared to the aggregate carrying value of $2,439 million (inclusive of the terminated interest rate swaps). The fair value of the Company’s variable-rate debt obligations at September 29, 2012 approximated their aggregate $84 million carrying value due to the variable interest rate and short-term nature of these instruments. |
