[1]	Represents the U.S. Treasury yield over the same period as the expected option term.
[2]	Represents the period of time that options granted are expected to be outstanding. Based on analysis of historical option exercise activity, the company has determined that all employee groups exhibit similar exercise and post-vesting termination behavior.
[3]	Amount is determined based on analysis of historical price volatility of the company's common stock over a period equal to the expected term of the options. The company also utilizes a market-based or “implied volatility” measure, on exchange-traded options in the company's common stock, as a reference in determining this assumption.
[4]	Represents the company's estimated cash dividend yield over the expected term of options.

- Definition

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
