Note 11—Fair Value Measurements

Items Measured at Fair Value on a Recurring Basis

The following table shows the fair value of our financial assets and financial liabilities that are required to be measured at fair value as of March 31, 2012 and December 31, 2011:


(In millions)	Balance			Level 1		Level 2			Level 3
March 31, 2012
Assets:
Investments	$	112.9		$	111.4	$	1.5			—
Liabilities:
Derivative instruments		(370.8	)		—		(370.8	)		—

December 31, 2011
Assets:
Investments	$	108.4		$	106.9	$	1.5			—
Liabilities:
Derivative instruments		(336.1	)		—		(336.1	)		—

The following section describes the valuation methodologies used to estimate or measure fair value, key inputs, and significant assumptions:

Investments – Investments consist of debt and equity securities with maturity dates greater than 90 days at the date of the security's acquisition. The majority of these securities are traded in active markets, have readily determined market values, and use Level 1 inputs. Securities for which there are not active markets or the market values are not readily determinable are valued using Level 2 inputs. All of these investments are included in either prepayments and other current assets or deferred charges and other in our consolidated balance sheets.

The fair value of investments in marketable securities were as follows:


(In millions)	March 31, 2012		December 31, 2011
Corporate bonds	$	1.5	$	1.5
Equity securities		2.9		2.4
Government bonds		106.5		102.5
Other liquid investments		2.0		2.0

Total investments	$	112.9	$	108.4

Gross unrealized gains and losses on marketable securities at March 31, 2012 and December 31, 2011 were not material.

Derivative instruments – The estimated fair values of our derivative instruments are derived from market prices obtained from dealer quotes for similar, but not identical, assets or liabilities. Such quotes represent the estimated amounts we would receive or pay to terminate the contracts. Derivative instruments are included in either deferred charges and other, or deferred credits and other, in our consolidated balance sheets. Our derivatives are recorded at their fair values, adjusted for the credit rating of the counterparty if the derivative is an asset, or adjusted for the credit rating of the Company if the derivative is a liability. See Note 6, "Derivative Instruments," for more information.

Items Disclosed at Fair Value

Long-term debt – The fair value of the Company's debt has been calculated based on the borrowing rates available as of March 31, 2012, for debt with similar terms and maturities, and based on market quotes of our publicly traded debt. As of March 31, 2012, the Company's outstanding debt had a fair value of $17,664.0 million and a carrying value of $19,891.8 million.

- Definition

Tabular disclosure of the fair value measurement of assets and liabilities which includes [financial] instruments measured at fair value that are classified in stockholders' equity. Such assets and liabilities may be measured on a recurring or nonrecurring basis. The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods. Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
