Government bonds include bonds issued or deemed to be guaranteed by government entities. Government bonds include instruments such as non-U.S. government bonds, U.S. Treasury securities, and U.S. agency securities.Marketable Debt Instruments

Marketable debt instruments include instruments such as commercial paper, corporate bonds, government bonds, bank deposits, asset-backed securities, municipal bonds, and money market fund deposits. When we use observable market prices for identical securities that are traded in less active markets, we classify our marketable debt instruments as Level 2. When observable market prices for identical securities are not available, we price our marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. We corroborate non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings.

Our marketable debt instruments that are classified as Level 3 are classified as such due to the lack of observable market data to corroborate either the non-binding market consensus prices or the non-binding broker quotes. When observable market data is not available, we corroborate our fair value measurements using non-binding market consensus prices and non-binding broker quotes from a second source.

The following tables present reconciliations for all assets and liabilities measured and recorded at fair value on a recurring basis using significant unobservable inputs (Level 3) for 2011 and 2010:

For all periods presented, gains and losses (realized and unrealized) included in earnings were primarily reported outside of operating income. During 2010, we transferred corporate bonds from Level 3 to Level 2 due to improved availability of observable market data and non-binding market consensus prices to value or corroborate the value of these instruments. Our policy is to reflect transfers in and transfers out at the beginning of the quarter in which a change in circumstances resulted in the transfer.

We elected the fair value option for loans made to third parties when the interest rate or foreign exchange rate risk was hedged at inception with a related derivative instrument. As of December 31, 2011, the fair value of our loans receivable for which we elected the fair value option did not significantly differ from the contractual principal balance based on the contractual currency. These loans receivable are classified within other current assets and other long-term assets. Fair value is determined using a discounted cash flow model with all significant inputs derived from or corroborated with observable market data. Gains and losses from changes in fair value on the loans receivable and related derivative instruments, as well as interest income, are recorded in interest and other, net. For all years presented, changes in the fair value of our loans receivable were largely offset by changes in the related derivative instruments, resulting in an insignificant net impact on our consolidated statements of income. Gains and losses attributable to changes in credit risk are determined using observable credit default spreads for the issuer or comparable companies and were insignificant for all years presented. We did not elect the fair value option for loans when the interest rate or foreign exchange rate risk was not hedged at inception with a related derivative instrument.

We elected this fair value option for the bonds issued in 2007 by the Industrial Development Authority of the City of Chandler, Arizona (2007 Arizona bonds). In connection with the 2007 Arizona bonds, we entered into a total return swap agreement that effectively converts the fixed-rate obligation on the bonds to a floating U.S.-dollar LIBOR-based rate. As a result, changes in the fair value of this debt are largely offset by changes in the fair value of the total return swap agreement, without the need to apply hedge accounting provisions. The 2007 Arizona bonds are included in long-term debt. As of December 31, 2011 and December 25, 2010, no other instruments were similar to the 2007 Arizona bonds for which we elected fair value treatment.

As of December 31, 2011, the fair value of the 2007 Arizona bonds did not significantly differ from the contractual principal balance. The fair value of the 2007 Arizona bonds was determined using inputs that are observable in the market or that can be derived from or corroborated with observable market data, as well as unobservable inputs that were significant to the fair value. Gains and losses on the 2007 Arizona bonds and the related total return swap are recorded in interest and other, net. We capitalize a portion of the interest associated with the 2007 Arizona bonds. We add capitalized interest to the cost of qualified assets and amortize it over the estimated useful lives of the assets. The remaining interest associated with the 2007 Arizona bonds is recorded as interest expense in interest and other, net.

Our non-marketable equity investments and non-financial assets, such as intangible assets and property, plant and equipment, are recorded at fair value only if an impairment charge is recognized. During 2011, we recognized $62 million of impairment charges on non-marketable equity investments held as of December 31, 2011 ($121 million of impairment charges during 2010 for non-marketable equity investments held as of December 25, 2010 and $187 million of impairment charges during 2009 for non-marketable equity investments held as of December 26, 2009). The fair value of the non-marketable equity investments at the time of impairment was $69 million during the year ended December 31, 2011 ($128 million during the year ended December 25, 2010 and $211 million during the year ended December 26, 2009). All of these assets were categorized as Level 3 in the fair value hierarchy.

A portion of our non-marketable equity investments was measured and recorded at fair value due to events or circumstances that significantly impacted the fair value of those investments, resulting in other-than-temporary impairment charges. We classified these measurements as Level 3, as we used unobservable inputs to the valuation methodologies that were significant to the fair value measurements, and the valuations required management judgment due to the absence of quoted market prices. We determine the fair value of our non-marketable equity investments using the market and income approaches. The market approach includes the use of financial metrics and ratios of comparable public companies. The selection of comparable companies requires management judgment and is based on a number of factors, including comparable companies' sizes, growth rates, industries, development stages, and other relevant factors. The income approach includes the use of a discounted cash flow model, which requires the following significant estimates for the investee: revenue, costs, and discount rates based on the risk profile of comparable companies. Estimates of revenues and costs are developed using available market, historical, and forecast data. The valuation of these non-marketable equity investments also takes into account variables such as conditions reflected in the capital markets, recent financing activities by the investees, the investees' capital structure, the terms of the investees' issued interests, and the lack of marketability of the investments.

We measure the fair value of our non-marketable equity investments, marketable equity method investments, indebtedness carried at amortized cost, and cost method loans receivable quarterly for disclosure purposes; however, the assets are recorded at fair value only when an impairment charge is recognized. The carrying amounts and fair values of financial instruments not recorded at fair value on a recurring basis as of December 31, 2011 and December 25, 2010 were as follows:

As of December 31, 2011 and December 25, 2010, the unrealized loss position of our non-marketable equity investments was not significant.

Our marketable equity method investments are primarily made up of our ownership interest in SMART Technologies, Inc. The fair value of our ownership interest in our marketable equity method investments was based on the quoted closing stock prices as of December 31, 2011 and December 25, 2010.

The carrying amount and fair value of loans receivable exclude loans measured and recorded at a fair value of $748 million as of December 31, 2011 ($642 million as of December 25, 2010). The carrying amount and fair value of long-term debt exclude long-term debt measured and recorded at a fair value of $131 million as of December 31, 2011 ($128 million as of December 25, 2010). Short-term debt includes our commercial paper outstanding as of December 31, 2011, and the carrying amount and fair value exclude drafts payable.

The fair value of our loans receivable is determined using a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. The credit quality of our loans receivable remains high, with credit ratings of BBB+/Baa1 or better as of December 31, 2011. The fair value of our long-term debt is determined using third-party market prices and discounted cash flow models that take into consideration variables such as credit-rating changes and interest rate changes.

The NVIDIA Corporation cross-license agreement liability in the preceding table was incurred as a result of entering into a long-term patent cross-license agreement with NVIDIA in January 2011. We agreed to make payments to NVIDIA over six years. For further information on the payment terms and recognition of licensed technology intangible assets, see “Note 17: Identified Intangible Assets.” As of December 31, 2011, the carrying amount of the liability arising from the agreement was classified within other accrued liabilities and other long-term liabilities, as applicable. The fair value is determined using a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data.
