There is an alternative way to calculate tax that is not based on number of shares. Not going to lie, I about had a heart attack when I got my first annual letter from Delaware. I think it's a right of passage.
He is referring to how the default franchise tax is calculated using the "Authorized Shares Method" which gives many an MI when they see they owe $20k+, without realizing you can use the "Assumed Par Value Capital Method" and your bill suddenly becomes like ~$500.
