[1] We estimated volatility using the historical volatility of our stock.

[2] The expected term represents the period of time that options granted are expected to be outstanding. We have utilized the simplified method permitted under share-based award accounting standards in determining the expected term for all option grants as we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited number of awards of equity shares that have reached expiration.
