Fair value of restricted stock units, description

The daily expected stock price volatility is based on a four-year historical volatility of the Company’s common stock. The daily-expected dividend yield is based on annual expected dividend payments. The average daily risk-free interest rate is based on the three-year treasury yield as of the grant date. Each of the tranches is calculated to have its own fair value and requisite service period. The fair value of each tranche is amortized over the requisite or derived service period, which is up to four years.
