Schedule of valuation methodology for assets and liabilities at fair value

We use the following valuation techniques and inputs for fair value measurements categorized within Level 2 of the fair value hierarchy:

Level 2 Fair Value Measurements:
Asset / Liability		Level		Valuation Techniques		Inputs
LME forward financial sales contracts		2		Discounted cash flows		Quoted LME forward market
MWP forward financial sales contracts		2		Discounted cash flows		Quoted MWP forward market
Fixed for floating swaps		2		Discounted cash flows		Quoted LME forward market, quoted MWP forward market
Nord Pool power price swaps		2		Discounted cash flows		Quoted Nord Pool forward market
NYMEX Henry Hub natural gas price swaps		2		Discounted cash flows		Quoted Henry Hub forward market
MISO Indiana Hub power price swaps		2		Discounted cash flows		Quoted Indy Hub forward market
FX swaps		2		Discounted cash flows		Euro/USD forward exchange rate

When valuing Level 3 assets and liabilities, we use certain significant unobservable inputs. Management incorporates various inputs and assumptions including forward commodity prices, commodity price volatility, and macroeconomic conditions, including interest rates and discount rates. Our estimates of significant unobservable inputs are ultimately based on our estimates of risks that market participants would consider when valuing our assets and liabilities.

The following table presents the inputs for fair value measurements categorized within Level 3 of the fair value hierarchy, along with information regarding significant unobservable inputs used to value Level 3 assets and liabilities:
