Valuation of debt and equity investments and certain liabilities [Abstract]

Valuation of debt and equity investments and certain liabilities

Valuation of debt and equity investments and certain liabilities

Debt and equity investments

We classify our investments as available for sale, trading, equity method or cost method.  Most of our investments are classified as available for sale.

Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models. See the fair-value discussion below. Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI on our Consolidated balance sheets. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E in our Consolidated statements of income.

We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities.  We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in SG&A. Changes in the fair value of debt securities classified as trading securities are recorded in OI&E.

Our other investments are not measured at fair value but are accounted for using either the equity method or cost method.  These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity-method investments are reflected in OI&E based on our ownership share of the investee’s financial results.  Gains and losses on cost-method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.

Details of our investments and related unrealized gains and losses included in AOCI are as follows:

At September 30, 2012, we had no available-for-sale investments with unrealized losses.  We did not recognize any credit losses related to available-for-sale investments for the nine months ended September 30, 2012 and 2011.

During the third quarter of 2012, we sold all of our remaining investments in auction-rate securities. For the nine months ended September 30, 2012 and 2011, the proceeds from sales, redemptions and maturities of short-term available-for-sale investments were $1.64 billion and $3.25 billion, respectively.  Gross realized gains and losses from these sales were not significant.

The following table presents the aggregate maturities of investments in money market funds and debt securities classified as available for sale at September 30, 2012:

One year or less	$	2,758

Fair-value considerations

We measure and report certain financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair value measurements.

Level 1 — Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date.

Level 2 — Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active.  Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations and some U.S. government agency securities. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.

Level 3 — Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment.  These values are generally determined using pricing models that utilize management estimates of market participant assumptions.

The following are our assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2012, and December 31, 2011.  These tables do not include cash on hand, assets held by our postretirement plans, or assets and liabilities that are measured at historical cost or any basis other than fair value.
