I'm using the equations given on this page to price forwards on an equity.
It's a basic equation that discounts dividends.
But my question is: What do we do about dividends that occur after the forward's expiration date?
For example, consider a stock that pays dividends on the last day of every month in the year. Say I want to price the forward that expires on the 15th of March. According to that webpage, I only need to discount dividends paid on January 1st, February 1st, and March 1st. But what about the dividend that will be paid on April 1st. On March 15th, we would be halfway through the month and the stock will have accrued half of the value of the next dividend. So how should I treat months after the forward? Thanks.
