- Definition

This is a measure of the performance of the entity's stocks and shares over time. It combines share price appreciation and dividends paid to show the total return to the shareholder expressed as an annualized percentage. It is calculated by the growth in capital from purchasing a share in the company assuming that the dividends are reinvested each time they are paid. This growth is expressed as a percentage as the compound annual growth rate. This measure is used in determining the vesting for our share-based compensation.

- 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.
