Stock options, valuation assumptions

The fair value of option grants were estimated at the date of grant during the years ended December 31, 2012, 2011, and 2010 based upon the following range of assumptions:

	2012		2011		2010
Expected volatility	77	%	76	%	80	%
Expected dividend yield	—	%	—	%	—	%
Risk-free interest rate	0.98% - 1.24%		1.94	%	2.16	%
Expected life	6 years		6 years		5 years

Stock appreciations rights, valuation assumptions

The fair value of granted SSARs has been estimated utilizing a Monte Carlo method. The Monte Carlo method is a statistical simulation technique used to provide the grant-date fair value of an award. As the issued SSARs were capped at maximum values, such attribute was considered in the simulation. The following table presents the weighted-average assumptions utilized in the valuations:

Expected volatility	71	%
Expected life from grant date	4.5 years
Expected dividend yield	—	%
Risk-free interest rate	0.61	%
