Restricted Stock Awards, Market-Based, Valuation assumptions [Table Text Block]

In January 2013, the Compensation Committee awarded a total of 41,570 market-based restricted shares to our executive officers. In addition to continuous employment, the vesting of these shares is contingent on the Company's total shareholder return ("TSR"), which is essentially the Company’s stock price change including any dividends, as compared to the TSR of a set group of 15 peer companies. The shares are measured over a three-year period ending on December 31, 2014 and can result in a payout between 0% and 200% of the total shares awarded. The weighted-average grant date fair value per market-based share for these awards granted was computed using the Monte Carlo pricing model using the following assumptions:

	Year Ended December 31,
	2013			2012
Expected term of award	3 years			3 years
Risk-free interest rate	0.4		%	0.3		%
Expected volatility	56.6		%	65.3		%
Weighted-average grant date fair value per share	$	49.04		$	36.54
