FAIR VALUE MEASUREMENT

Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs). FCX recognizes transfers between levels at the end of the reporting period. FCX did not have any significant transfers in or out of Level 1, 2, or 3 for third-quarter 2013.

A summary of the carrying amount and fair value of FCX’s financial instruments other than cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and dividends payable follows (in millions):

Valuation Techniques

Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Fixed income securities (U.S. core fixed income funds, government securities, corporate bonds, asset-backed securities and municipal bonds) are valued using a bid evaluation or a mid evaluation. A bid evaluation is an estimated price at which a dealer would pay for a security. A mid evaluation is the average of the estimated price at which a dealer would sell a security and the estimated price at which a dealer would pay for a security. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy.

Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.

FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales have critical inputs of quoted monthly LME or COMEX copper forward prices and the London PM gold forward price at each reporting date based on the month of maturity; however, FCX's contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.

FCX's derivative financial instruments for crude oil options are valued using an option pricing model, which uses various inputs including IntercontinentalExchange, Inc. (ICE) crude oil prices, volatilities, interest rates and contract terms. FCX's derivative financial instruments for crude oil and natural gas swaps are valued using a pricing model that has various inputs including NYMEX and ICE price quotations, interest rates and contract terms. Valuations are adjusted for credit quality, using the counterparties' credit quality for asset balances and FCX's credit quality for liability balances. For asset balances, FCX uses the credit default swap value for counterparties when available or the spread between the risk-free interest rate and the yield rate on the counterparties' publicly traded debt for similar instruments (which considers the impact of netting agreements on counterparty credit risk, including whether the position with the counterparty is a net asset or net liability). The 2013 and 2014 crude oil and natural gas swaps are classified within Level 2 of the fair value hierarchy because the inputs used in the valuation models are directly or indirectly observable for substantially the full term of the instruments. The 2013, 2014 and 2015 crude oil options are classified within Level 3 of the fair value hierarchy because the inputs used in the valuation models are not observable for substantially the full term of the instruments. The significant unobservable inputs used in the fair value measurement of the crude oil options are implied volatilities and deferred premiums. Significant increases (decreases) in implied volatilities in isolation would result in a significantly higher (lower) fair value measurement. The implied volatilities ranged from 18 percent to 46 percent, with a weighted average of 25 percent. The deferred premiums ranged from $5.15 per Bbl to $7.22 per Bbl, with a weighted average of $6.35 per Bbl. Refer to Note 9 for further discussion of these derivative financial instruments.

FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 9 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices.

The fair value of warrants associated with the Plains Offshore Preferred Stock was determined with an option pricing model that used unobservable inputs. The inputs used in the valuation model are the estimated fair value of the underlying Plains Offshore common stock, expected exercise price, expected term, expected volatility and risk-free interest rate. The assumptions used in the valuation model are highly subjective because the common stock of Plains Offshore is not publicly traded. As a result, these warrants are classified within Level 3 of the fair value hierarchy. The expected volatilities ranged from 20 percent to 54 percent, with a weighted average of 28 percent. Refer to Note 2 for further discussion of the Plains Offshore warrants.

Long-term debt, including the current portion, is valued using prices obtained from a readily available pricing source and, as such, is classified within Level 2 of the fair value hierarchy.

At December 31, 2012, FCX's investment in MMR's 5.75% Convertible Perpetual Preferred Stock, Series 2 (MMR investment) was not actively traded; therefore, FCX valued its MMR investment based on a pricing simulation model that used the quoted market prices of MMR's publicly traded common stock as the most significant observable input and other inputs, such as expected volatility, expected settlement date and risk-free interest rate. Therefore, this investment was classified within Level 2 of the fair value hierarchy. FCX's shares of MMR's 5.75% Convertible Perpetual Preferred Stock, Series 2 were canceled in connection with the acquisition of MMR.

A summary of the changes in the fair value of FCX's Level 3 instruments follows (in millions):



	Crude Oil				Plains Offshore
	Options				Warrants
Fair value at December 31, 2012	$	—			$	—
Derivative financial instruments assumed in the PXP acquisition	(83		)		(12		)
Net unrealized (losses) gains included in earnings related to
assets and liabilities still held at the end of the period	(135		)	^a	1			^b
Fair value at September 30, 2013	$	(218	)		$	(11	)


a.	Realized and unrealized (losses) gains are recorded in revenue. There were no realized gains for the first nine months of 2013.


b.	Realized and unrealized (losses) gains are recorded in other income. There were no realized gains for the first nine months of 2013.

The techniques described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at September 30, 2013, except for warrants (refer to Note 2 for discussion of warrants).

Refer to Note 2 for the levels within the fair value hierarchy associated with other assets acquired, liabilities assumed and redeemable noncontrolling interest related to second-quarter 2013 acquisitions.
