We account for the Glencore Metal Agreement as a derivative instrument under ASC 815. Under the Glencore Metal Agreement, pricing is based on then-current Midwest market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium.

The Glencore Sweep Agreement is for all metal produced in the U.S. in 2012, less existing sales agreements and high-purity metal sales. The term of the contract may be extended for one year upon mutual agreement.
