What is a 409(a) valuation ?
For a private company, 409(a) valuation decides the value of stock options to be granted to your employees. Usually a DCF or backsolve valuation or a combination is done to get to the option price. I created a model to calculate option pricing using backsolve method. Please feel free to use it to validate your 409(a) valuation.
With my compliments, you can follow my slideshow guide to create DCF valuation.
