We believe that all factors listed within SAB 107 as prerequisites for utilizing the simplified method apply to us and to our share-based compensation arrangements. We intend to utilize the simplified method for the foreseeable future until more detailed information about exercise behavior becomes available.

We intend to utilize the simplified method for the foreseeable future until more detailed information about exercise behavior becomes available. Expected volatility is based on historical volatility of our common stock. We utilize risk-free interest rates based on U.S. treasury instruments, the term of which is consistent with the expected term of the share-based award.
This valuation model requires the input of highly subjective assumptions, including the expected stock volatility, estimated award terms and risk-free interest rates for the expected terms. To estimate the expected terms, we utilize the simplified method for “plain vanilla” options discussed in the SEC’s Staff Accounting Bulletin 107, or SAB 107.
In the case of stock options, the fair value is estimated on the grant dates using the Black-Scholes valuation model.
