You have valued a business, using discounted cash flow models, at $250 million for a private sale. The business, which does make money, had revenues of $200 million in the most recent year. (The average firm has revenues of $10 million.) How much of a liquidity discount would you apply to this firm:

a. Based on the Silber regression?

b. Based on correcting the average discount (25%) for the size of the firm?
