| Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions [Table Text Block] |
The fair value of stock options was estimated at the grant date using the Black-Scholes-Merton option pricing model with the following weighted-average assumptions:
| | | | | | | | | | | 2012 | | 2011 | | 2010 | Risk-free interest rate (1) | 1.12 | % | | 2.27 | % | | 2.84 | % | Price Volatility (2) | 55.9 | % | | 54.0 | % | | 54.0 | % | Expected term (years) (3) | 6.17 |
| | 6.25 |
| | 6.25 |
| Dividend yield (4) | — |
| | — |
| | — |
|
| | (1) | Represents the yield on U.S. Treasury securities with a term consistent with the expected term of the stock options. |
| | (2) | For the first two years following the Company's IPO, this was based on the historical volatility of selected comparable companies over a period consistent with the expected term of the stock options because the Company had a limited history of being publicly traded. Comparable companies were selected primarily based on industry, stage of life cycle, and size. Beginning with the second anniversary of the IPO n May 2012, the Company began using its own volatility as an additional input in the determination of expected volatility. |
| | (3) | Calculated utilizing the “simplified” methodology prescribed by SAB No. 107 due to the lack of historical exercise data necessary to provide a reasonable basis upon which to estimate the term. |
| | (4) | The Company does not currently plan on paying regular dividends. |
