Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In accordance with authoritative guidance for fair value measurements, certain assets and liabilities are required to be recorded at fair value and classified within a fair value hierarchy based on inputs used when measuring fair value. We have investments in equity securities classified as available-for-sale and an immaterial amount of forward exchange contracts that are adjusted to fair value on a recurring basis. The fair values of our investments in available-for-sale securities were determined using quoted market prices from daily exchange traded markets and are classified within Level 1 of the valuation hierarchy. The fair values of our available-for-sale securities are $11 million, $14 million and $12 million as of June 30, 2012, December 31, 2011 and June 30, 2011, respectively, and are included in other non-current assets in the consolidated balance sheets. Other financial instruments, including cash and equivalents and short-term investments, are recorded at cost, which approximates fair value because of the short-term maturity and highly liquid nature of these instruments. The fair value of our total borrowings for each period presented is $1.3 billion and was estimated based on quoted market prices.

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