DERIVATIVE FINANCIAL INSTRUMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

Palmarejo Gold Production Royalty

On January 21, 2009, the Company entered into a gold production royalty transaction with Franco-Nevada Corporation. The royalty covers 50% of the life of mine production from the Palmarejo mine and adjacent properties. The royalty transaction included a minimum obligation of 4,167 ounces per month that ends when payments have been made on a total of 400,000 ounces of gold. As of June 30, 2012, a total of 224,710 ounces of gold remain outstanding under the minimum royalty obligation.

The price volatility associated with the minimum royalty obligation is considered an embedded derivative financial instrument under U.S. GAAP. As such, the Company is required to recognize the change in fair value of the remaining minimum obligation due to the changing gold prices. Unrealized gains are recognized in periods when the gold price has decreased from the previous period and unrealized losses are recognized in periods when the gold price increases. The fair value of the embedded derivative is reflected net of the Company's current credit adjusted risk free rate, which was 5.3% and 5.7% at June 30, 2012 and December 31, 2011, respectively. The fair value of the embedded derivative at June 30, 2012 and December 31, 2011, based on forward gold prices averaging approximately $1,630 and $1,610 per ounce, respectively, was a liability of $146.7 million and $159.4 million, respectively. During the three and six months ended June 30, 2012 and 2011, mark-to-market adjustments for this embedded derivative amounted to a gain of $25.1 million and a loss of $4.0 million, and a gain of $12.7 million and a loss of $2.9 million respectively.

Payments on the royalty obligation occur monthly resulting in a decrease to the carrying amount of the minimum obligation and the derivative liability and the recognition of realized gains or losses as a result of changing prices for gold. Each monthly payment is an amount equal or greater of the minimum of 4,167 ounces of gold or 50% of the actual gold production per month multiplied by the excess of the monthly average market price of gold above $400 per ounce (which $400 floor is subject to a 1% annual inflation compounding adjustment beginning on January 21, 2013). For the three and six months ended June 30, 2012 and 2011, realized losses on settlement of the liabilities were $11.0 million, and $9.7 million and $24.2 million and $17.2 million, respectively. The mark-to-market adjustments and realized losses are included in fair value adjustments, net in the consolidated statement of operations.

Forward Foreign Exchange Contracts

The Company periodically enters into forward foreign currency contracts to reduce the foreign exchange risk associated with forecasted Mexican peso (“MXP”) operating costs at its Palmarejo mine. At June 30, 2012, the Company had MXP foreign exchange contracts of $26.1 million in U.S. dollars. These contracts require the Company to exchange U.S. dollars for MXP at a weighted average exchange rate of 13.37 MXP to each U.S. dollar and the Company had a liability with a fair value of $0.4 million at June 30, 2012. At December 31, 2011, the Company had MXP foreign exchange contracts of $25.5 million in U.S. dollars. These contracts required the Company to exchange U.S. dollars for MXP at a weighted average exchange rate of 12.40 MXP to each U.S. dollar and the Company had a liability with a fair value of $3.2 million at December 31, 2011. The Company recorded mark-to-market gains on these contracts of $0.1 million and $2.8 million for the three and six months ended June 30, 2012, respectively. The Company recorded mark-to-market gains (losses) of $(0.7) million and $0.3 million for the three and six months ended June 30, 2011, respectively. These mark-to-market adjustments are reflected in fair value adjustments, net. The Company recorded realized losses of $1.2 million and $1.9 million in production costs applicable to sales during the three and six months ended June 30, 2012 , respectively. The Company recorded realized gains of $0.9 million and $1.1 million in production costs applicable to sales during the three and six months ended June 30, 2011, respectively.

Concentrate Sales Contracts

The Company enters into concentrate sales contracts with third-party smelters. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted metal prices. The provisionally priced sales contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates at the forward price at the time of sale. The embedded derivative, which is the final settlement price based on a future price, does not qualify for hedge accounting. These embedded derivatives are recorded as derivative assets (in Prepaid expenses and other) or derivative liabilities (in Accrued liabilities and other) on the balance sheet and are adjusted to fair value through earnings each period until the date of final settlement. At June 30, 2012, the Company had outstanding provisionally priced sales of $20.2 million, consisting of 0.4 million ounces of silver and 5,698 ounces of gold, which had a fair value of $19.9 million including the embedded derivative. At December 31, 2011, the Company had outstanding provisionally priced sales of $22.5 million consisting of 0.2 million ounces of silver and 9,701 ounces of gold, which had a fair value of approximately $21.7 million including the embedded derivative.

As of June 30, 2012, in connection with the Kensington term facility, the Company had outstanding call options requiring it to deliver 111,000 ounces of gold at a weighted average strike price of $1,971.94 per ounce if the market price of gold exceeds the strike price. At June 30, 2012, the Company had outstanding put options allowing it to sell 156,000 ounces of gold at a weighted average strike price of $958.16 per ounce if the market price of gold were to fall below the strike price. The contracts will expire over the next four years.

During the six months ended June 30, 2012 no gold call options expired. During the six months ended June 30, 2012, 34,000 ounces of gold put options expired at a weighted average strike price of $923.34 per ounce, resulting in a realized loss of $1.4 million.

The Company recognized mark to market losses of $0.3 million and $0.3 million associated with this silver in the three and six months ended June 30, 2012, respectively. The Company recognized mark to market gains (losses) of $(0.4) million and $0.5 million associated with this silver in the three and six months ended June 30, 2011, respectively.

Credit Risk

The credit risk exposure related to any potential derivative instruments is limited to the unrealized gains, if any, on outstanding contracts based on current market prices. To reduce counter-party credit exposure, the Company deals with financial institutions management deems credit worthy and limits credit exposure to each. The Company does not anticipate non-performance by any of its counterparties. In addition, to allow for situations where positions may need to be revised, the Company deals only in markets that management considers highly liquid.
