Fair Value Measurements.

U.S. GAAP requires enhanced disclosures about investments and non-recurring non-financial assets and non-financial liabilities that are measured and reported at fair value and has established a hierarchal disclosure framework that prioritizes and ranks the level of market price observability used in measuring investments or non-financial assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of investment and the characteristics specific to the investment. Investments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value.

Investments and non-financial assets and/or liabilities measured and reported at fair value are classified and disclosed in one of the following categories:

Level 1 - Quoted prices are available in active markets for identical investments as of the reporting date. The types of investments included in Level 1 include listed equities and listed derivatives. We do not adjust the quoted price for these investments, even in situations where we hold a large position.

Level 2 - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. Investments that are generally included in this category include corporate bonds and loans, less liquid and restricted equity securities and certain over-the-counter derivatives. The inputs and assumptions of our Level 2 investments are derived from market observable sources including reported trades, broker/dealer quotes and other pertinent data.

Level 3 - Pricing inputs are unobservable for the investment and non-financial asset and/or liability and include situations where there is little, if any, market activity for the investment or non-financial asset and/or liability. The inputs into the determination of fair value require significant management judgment or estimation. Fair value is determined using comparable market transactions and other valuation methodologies, adjusted as appropriate for liquidity, credit, market and/or other risk factors.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the investment. Significant transfers, if any, between the levels within the fair value hierarchy are recognized at the beginning of the reporting period when changes in circumstances require such transfers.

The changes in investments measured at fair value for which our Investment segment has used Level 3 input to determine fair value are as follows:



	Three Months Ended March 31,
	2014			2013
	(in millions)
Balance at January 1	$	287		$	288
Gross realized and unrealized gains	—			4
Gross proceeds	(1		)	(2		)
Balance at March 31	$	286		$	290

Unrealized losses of less than $1 million are included in earnings related to Level 3 investments still held at March 31, 2014 by our Investment segment. Total realized and unrealized gains and losses recorded for Level 3 investments, if any, are reported in net (loss) gain from investment activities in our consolidated statements of operations.

The Investment Funds held one Level 3 corporate debt investment at March 31, 2014. Fair value was determined through yield analysis of comparable loans to which we applied a risk premium that we determined to be appropriate, which resulted in a lower valuation for our Level 3 investment. Increasing the risk premium by 1% would result in a 2% decrease in the fair value of the loan. Decreasing the risk premium by 1% would have no effect on the fair value of the loan because the loan is callable at par.
