Consideration for Closely Held Securities—DLOM Theoretical Models (Part II of II) This article summarizes the factors (and the empirical evidence) that the analyst may consider in the measurement of a discount for lack of marketability (DLOM) valuation adjustment associated with non-controlling securities of a closely held company. This security-level DLOM is different from the entity-level DLOM that is applied at the closely held company level. This second part of the article focuses on theoretical DLOM measurement models: the option pricing and DCF models.
