The additions to the SCT includes the

year-end

Fair Market Value (“FMV”) of the awards granted for the applicable year plus or minus the annual change in the FMV as of the

year-end

for unvested awards granted in prior years as well as plus or minus the change in the FMV as of the date of vesting for awards vested in each applicable year versus the ending stock price of the prior year. The FMV of each PSU grant was estimated on the measurement date using a Monte Carlo pricing model and is reported on the table below. In addition, the FMV for each SAR grant was estimated on the measurement date using a Black Scholes pricing model; details noted below.
