[1] We estimate volatility based on the historical volatility of OCN's common stock over the most recent period that corresponds with the estimated expected life of the option.
[2] For the options valued using the Black-Scholes model we determined the expected life based on historical experience with similar awards, giving consideration to the contractual term, exercise patterns and post vesting forfeitures. The expected term of the options valued using the lattice (binomial) model is derived from the output of the model. The lattice (binomial) model incorporates exercise assumptions based on analysis of historical data. For all options, the expected life represents the period of time that options granted were expected to be outstanding at the date of the award.
