Example of Minority and Marketability Discounts

Wieviel sind Minderheitsbeteiligungen wert?
Wieviel Wertsteigerung bringt Börsengang?

according to Shannon Pratt

The discounts are taken in chain, that is, they are multiplicative, not additive:

Controlling interest value $100 per share
Less: 30% minority discount 30

Value if publicly traded $ 70 per share

Less 40% discount for lack
marketability 28 per share

Closely held minority value $ 42 per share
