The discount for lack of control is separate and distinguishable from the discount for lack of marketability. It is the valuation professional's task to quantify the lack of marketability of an interest in a privately held company. Because, in this case, the subject interest is not a controlling interest in the Company, and the owner of that interest cannot compel liquidation to convert the subject interest to cash quickly, and no established market exists on which that interest could be sold, the discount for lack of marketability is appropriate.
