Fair Value Measurements and Derivatives
Note 12.  Fair Value Measurements and Derivatives

In measuring the fair value of our assets and liabilities, we use market data or assumptions that we believe market participants would use in pricing an asset or liability including assumptions about risk when appropriate.  Our valuation techniques include a combination of observable and unobservable inputs.

Fair value measurements on a recurring basis — Assets and liabilities that are carried in our balance sheet at fair value are as follows:

Foreign currency derivatives — The total notional amounts of outstanding foreign currency derivatives as of June 30, 2011 and December 31, 2010 were $80 and $108 comprised of currency forward contracts involving the exchange of U.S. dollars, euros, British pounds, Canadian dollars, Swiss francs, Swedish krona, Japanese yen, Hungarian forints, South African rand and Indian rupees as well as a cross-currency swap involving the exchange of Australian dollars and South African rand.  At June 30, 2011, currency forward contracts with notional amounts of $48 were designated as cash flow hedges.

Amounts to be reclassified to earnings — Deferred gains at June 30, 2011 and losses at December 31, 2010 reported in AOCI include de minimis amounts expected to be reclassified to earnings during the next twelve months.  Amounts expected to be reclassified to earnings assume no change in the current hedge relationships or to June 30, 2011 market rates.  A de minimis amount was reclassified from AOCI to earnings in the first half of 2011.

Substantially all of the notes receivable balance consists of one note, due 2019, obtained in connection with a divestiture in 2004.  Its fair value is adjusted each quarter to the lower of its callable value or its market value, which is based on the publicly traded debt of the operating subsidiary of the obligor.  The fair value of the note at June 30, 2011 and December 31, 2010 approximated the callable value and we believe that the note will be paid in full at the end of the term or sooner.
Fair value measurements on a nonrecurring basis — In addition to items that are measured at fair value on a recurring basis, we also have long-lived assets that may be measured at fair value on a nonrecurring basis.  These assets include intangible assets and property, plant and equipment which may be written down to fair value as a result of impairment.
