Schedule of Valuation Assumptions | Stock-based compensation expense related to stock options was estimated on the date of grant using the Black-Scholes option-pricing model with various assumptions. Expected volatilities were based on historical volatility as the Corporation does not expect that future volatility over the expected term of the options is likely to differ from the past. The Corporation used a calculation method based on the historical daily frequency for a period of time equal to the expected term. The Corporation used the current dividend yield as there are no plans to substantially increase or decrease its dividends. The Corporation used historical exercise experience to determine the expected term. The risk-free interest rate was selected based on yields from treasury securities as published by the Federal Reserve equal to the expected term of the options. The amount of stock-based compensation expense recognized during a period is also based on the portion of the stock options that are ultimately expected to vest. The Corporation estimates pre-vesting forfeitures at the time of grant by analyzing historical data and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.
