Lack of Marketability of
Controlling Interests in Businesses

February 2023

The International Glossary of Business Valuation Terms defines a “Controlling Interest” as “an ownership interest in a business that conveys the economic benefits of Control to the holder(s) of such interest.  “Control” is defined as “a level of ownership having sufficient rights (e.g., voting) to direct the management, policies, and disposition of a business.”  “Marketability” is defined as “the ability to quickly convert property to cash at minimal cost”. 

Most people recognize that a minority interest in a business that is not publicly-traded (and has sufficient trading volume) suffers from lack of marketability.  This lack of marketability results in a lower value than if it was publicly-traded.  This lowering of value is called a “lack of marketability discount” or a “discount for lack of marketability”.  Fewer people recognize that even controlling interests often suffer from lack of marketability unless they are publicly-traded, and have sufficient trading volume.  Since it is usually easier to sell a controlling interest in a business than a minority interest, the discount in value from lack of marketability for a controlling interest is usually lower than that for a minority interest in the same business. 

A controlling interest can achieve marketability by either a public offering or a private sale, while a minority interest typically only has a private sale option, or hope that the controlling interest takes the business public at some point. 

As stated in Valuing a Business, the following factors need to be considered when determining the lack of marketability discount for a controlling interest: 

• an uncertain time horizon to complete the offering or sale
• Costs to prepare and execute the offering or sale (legal,
   accounting, administrative, brokerage)
• Risk as to eventual sales price
• Non-cash and deferred transaction proceeds
• Inability to hypothecate 

In summary, due to these factors, it is generally accepted that the discount for lack of marketability for a controlling interest should normally be lower than for a minority interest in the same business.  This is generally true as a controlling interest has more options to achieve marketability.
