NOTE 6 — FAIR VALUE OF FINANCIAL INSTRUMENTS

The following represents the assets and liabilities of the Company measured at fair value at December 31, 2011 and 2010:

There were no financial instruments measured at fair value that were in a liability position at December 31, 2010.

Financial assets classified in Level 1 at December 31, 2011 and 2010 include money market funds and available-for-sale marketable securities. The valuation of these instruments is determined using a market approach, taking into account current interest rates, creditworthiness and liquidity risks in relation to current market conditions, and is based upon unadjusted quoted prices for identical assets in active markets.

The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for substantially the full term of the financial instrument. Level 2 securities primarily include derivative financial instruments valued using financial models that use as their basis readily observable market parameters. At December 31, 2011 and 2010, such derivative financial instruments included our existing foreign currency exchange contracts. The fair value of the foreign currency exchange contracts is based on forward market prices and represents the estimated amount we would receive or pay to terminate these agreements at the reporting date, taking into account creditworthiness, nonperformance risk and liquidity risks associated with current market conditions.

The derivative financial assets classified within Level 3 at December 31, 2011 and 2010 include an embedded derivative instrument related to certain supply agreements with one of our U.S. Iron Ore customers. The agreements include provisions for supplemental revenue or refunds based on the customer's annual steel pricing at the time the product is consumed in the customer's blast furnaces. We account for this provision as a derivative instrument at the time of sale and mark this provision to fair value as a revenue adjustment each reporting period until the product is consumed and the amounts are settled. The fair value of the instrument is determined using a market approach based on an estimate of the annual realized price of hot rolled steel at the steelmaker's facilities, and takes into consideration current market conditions and nonperformance risk.

The Level 3 derivative assets and liabilities at December 31, 2011 also consisted of freestanding derivatives related to certain supply agreements with our U.S. Iron Ore and Eastern Canadian Iron Ore customers. In 2011, we reached final pricing settlement with a majority of our U.S. Iron Ore customers. However, in some cases we still are working to revise components of the pricing calculations referenced within our supply agreements to incorporate new pricing mechanisms as a result of the changes to historical benchmark pricing. As a result, we have recorded certain shipments made during 2011 on a provisional basis until final settlement is reached. The pricing provisions are characterized as freestanding derivatives and are required to be accounted for separately once the product is shipped. The derivative instrument, which is settled and billed once final pricing settlement is reached, is marked to fair value as a revenue adjustment each reporting period.

In the second quarter of 2011 and the third quarter of 2010, we revised the inputs used to determine the fair value of these derivatives to include 2011 published pricing indices and settlements realized by other companies in the industry. Prior to this change, the fair value primarily was determined based on significant unobservable inputs to develop the forward price expectation of the final price settlement for 2011. Based on these changes to the determination of the fair value, we transferred $20.0 million of derivative assets from a Level 3 classification to a Level 2 classification within the fair value hierarchy in the second quarter of 2011. A similar revision to the inputs used to determine the fair value of these derivatives was made in the third quarter of 2010 and, based on the changes, we transferred $161.8 million of derivative assets from a Level 3 classification to a Level 2 classification within the fair value hierarchy at that time.

Due to pending revisions to the terms of certain of our customer supply agreements that were initiated during the fourth quarter of 2011, the fair value determination for these derivatives has again been primarily based on significant unobservable inputs to develop the forward price expectation of the final price settlement for 2011. Based on these changes to the determination of the fair value, we transferred $49.0 million of derivative assets from a Level 2 classification to a Level 3 classification within the fair value hierarchy in the fourth quarter of 2011. The fair value of our derivatives is determined using a market approach and takes into account current market conditions and other risks, including nonperformance risk.

Substantially all of the financial assets and liabilities are carried at fair value or contracted amounts that approximate fair value. We had no financial assets and liabilities measured at fair value on a non-recurring basis at December 31, 2011 and 2010.

We recognize any transfers between levels as of the beginning of the reporting period, including both transfers into and out of levels. There were no transfers between Level 1 and Level 2 of the fair value hierarchy during the year ended December 31, 2011. As noted above, there was a transfer from Level 3 to Level 2 in each of the second quarter of 2011 and the third quarter of 2010, and a transfer from Level 2 to Level 3 in the fourth quarter of 2011, as reflected in the table below. The following table represents a reconciliation of the changes in fair value of financial instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2011 and 2010.

Gains and losses included in earnings are reported in Product revenue in the Statements of Consolidated Operations for the years ended December 31, 2011 and 2010.

The carrying amount and fair value of our long-term receivables and long-term debt at December 31, 2011 and 2010 were as follows:

The terms of one of our U.S. Iron Ore pellet supply agreements require supplemental payments to be paid by the customer during the period 2009 through 2013, with the option to defer a portion of the 2009 monthly amount up to $22.3 million in exchange for interest payments until the deferred amount is repaid in 2013. Interest is payable by the customer quarterly and began in September 2009 at the higher of 9 percent or the prime rate plus 350 basis points. As of December 31, 2011 and 2010, a receivable of $22.3 million had been recorded in Other non-current assets in the Statement of Consolidated Financial Position reflecting the terms of this deferred payment arrangement. The fair value of the receivable of $20.8 million and $19.5 million at December 31, 2011 and 2010, respectively, is based on a discount rate of 4.5 percent, which represents the estimated credit-adjusted risk-free interest rate for the period the receivable is outstanding.

In 2002, we entered into an agreement with Ispat that restructured the ownership of the Empire mine and increased our ownership from 46.7 percent to 79 percent in exchange for the assumption of all mine liabilities. Under the terms of the agreement, we indemnified Ispat from obligations of Empire in exchange for certain future payments to Empire and to us by Ispat of $120.0 million, recorded at a present value of $26.5 million and $32.8 million at December 31, 2011 and 2010, respectively. The fair value of the receivable of $30.7 million and $38.9 million at December 31, 2011 and 2010, respectively, is based on a discount rate of 2.58 percent, which represents the estimated credit-adjusted risk-free interest rate for the period the receivable is outstanding.

The fair value of long-term debt was determined using quoted market prices or discounted cash flows based upon current borrowing rates. The term loan and revolving loan are variable rate interest and approximate fair value. See NOTE 7 — DEBT AND CREDIT FACILITIES for further information.
