Discount for Lack of Marketability (DLOM)

Definition

A reduction applied to the value of an ownership interest to reflect the absence of a ready market for its sale. DLOM is commonly applied to interests in private companies where shares cannot be easily traded on a public exchange. Empirical studies, including restricted stock studies and pre-IPO transaction studies, typically suggest DLOMs ranging from 15% to 35%, though the appropriate discount depends on factors such as expected holding period, dividend policy, and prospects for a liquidity event.

Complementary Terms

Concepts that frequently appear alongside Discount for Lack of Marketability (DLOM) in practice.

Marketability Discount

A reduction applied to the value of an ownership interest to reflect the lack of a ready market in which to sell the interest quickly and at full value. Also known as a discount for lack of marketability (DLOM), this adjustment is particularly significant for private company valuations where shares cannot be readily traded on a public exchange.

Minority Interest Discount

A reduction applied to the pro rata value of a business to reflect the disadvantages of owning a non-controlling interest, including inability to direct business strategy, set compensation, force distributions, or compel liquidation. The minority interest discount is the mathematical complement of the control premium and is typically applied when valuing interests of less than 50% in private companies.

Minority Discount

A reduction applied to the pro-rata value of a business interest to reflect the lack of control associated with a minority ownership position. Minority discounts account for the inability of minority shareholders to influence key decisions such as dividend policy, asset sales, and management appointments.

Discount for Lack of Control (DLOC)

A reduction applied to the value of a minority ownership interest to reflect the holder's inability to influence key business decisions such as dividend policy, asset sales, or management appointments. DLOC is the inverse of the control premium and is typically derived from observed control premium data in comparable transactions.

Key Person Discount

A reduction to business value reflecting the risk that the departure of one or more critical individuals would materially impair the company's earnings, relationships, or operational capability. Key person discounts are most significant in professional services, early-stage ventures, and founder-led businesses where revenue concentration or specialised expertise is tied to specific individuals.

Merchant Discount Rate (MDR)

The total fee charged to a merchant for processing a payment card transaction, expressed as a percentage of the transaction value plus a fixed per-transaction fee. The MDR comprises three components: the interchange fee (paid to the issuing bank), the card network assessment fee (paid to Visa/Mastercard), and the acquirer's markup.

Risk-Adjusted Discount Rate

A discount rate that incorporates a premium reflecting the specific risks associated with a particular asset, cash flow stream, or investment. In intangible asset valuations, risk-adjusted discount rates are typically higher than the weighted average cost of capital to reflect the greater uncertainty inherent in intangible asset cash flows compared to tangible assets.

Conglomerate Discount

The phenomenon where the market values a diversified conglomerate at less than the aggregate value of its individual business units if they were operated independently. The conglomerate discount — typically estimated at 10% to 15% — reflects investor concerns about capital allocation inefficiency, cross-subsidisation, management complexity, and reduced transparency across disparate business lines.
