Valuing minority interests
Valuing minority interests requires the consideration of two key concepts:
- Control premiums. That an investor may be prepared to pay a premium for control of the business, ie. pay more than simply the sum of all the minority interests
- Marketability. Minority shares held in a private company are less marketable, less liquid, than shares held in a listed company
The market share price of a listed company represents the portfolio interest price. That is to say the price of a small parcel of shares, typically less than 5% of the company. The price represents the stock price at which small parcels of shares are traded
In takeovers of listed companies, an acquirer will sometimes (but not always) pay a premium above the market price. The inference is that buyers are prepared to pay a premium for control. This control premium depends on such factors: as the industry, whether the acquirer already as a share in the target and how heavily traded the companies are.
According to an RSM study on observed premiums in takeovers in Australia, premiums were observed to be the highest in the Pharmaceutical and Biotech industries with offer prices at an average 38% above market prices 2 to 20 days before the offer. Real estate had the lowest observed premiums, an average of 21%.
Transactions with the lowest market value, less than $25m, had the highest observed control premiums, an average of 49%. Whereas the largest transactions, over $500m, had the lowest premiums, an average of 23%. Which is not surprising. A large company will have heavily traded, liquid stock and there is also a lot more company information available to investors, compared to a small traded company.
In a Mckinsey study, control premiums were observed averaging 40%. Although in this case, the study appears to attribute the premium as a nod to buyer synergy.
The justifications for an acquirer paying a premium for control may include:
- controlling the composition of the board and management
- controlling decision making such as strategy and financial structure
- controlling cash flow and the nature and timing of dividends
The acquirer is expecting to improve the earnings of the target and may also expect some synergy benefits in merging operations (where it’s a strategic buyer vs an investment buyer).
The matter is far from clear. A common current argument is that Control in its self is not the basis for a control premium above a public share price. What matters is that, after an acquisition, the acquired company is now under a different management/ stewardship. A price higher than the publicly traded price might be reasonable if the new management expects to improve cash flow or reduce risk.
See the Exposure Draft, The Measurement and Application of Market Participant Acquisition Premiums. Issued in 2015 by the Appraisal Foundation. 090115 Exposure Draft Measurement and Application of Market Participant Acquisition Premiums
The minority discount is simply the inverse of the observed control premium. A minority discount is not implicit, it is simply observed and implied.
Key issues in valuing minority interests include consideration of the following:
- No control on cash flow. Subject to managements discretion on dividend policy
- No control on strategy, subject to the board’s decisions
- Liquidity. Minority interests in public companies can be sold instantaneously. Selling 100% of the shares in a company takes time
Marketability of private companies
In contrast, shares in private companies are not liquid. There is no ready market. They can not be sold instantaneously. Buyers need to be found. The Discount for Lack of Marketability exists to value a minority holding in a private company compared to what that interest would worth if the company was listed.
“The Discount for Lack of Marketability (DLOM) is an amount or percentage deducted from the value of an ownership interest to reflect the relative absence of marketability”, AICPA
Valuing minority interests in private companies requires understanding other additional factors, such as:
- Restrictions on the transfer of shares, per the shareholder agreement. For example, shareholder approval may be requres, first refusal rights may exist for other shareholders and there maybe a share price formula in the agreement
- Unlisted companies may provide little financial disclosure to private investors
- Private company investors do not benefit from the intense scrutiny of the press and analysts of public companies.
- Private company investors have few shareholder protections
Evidence for DLOM
There are two key studies that provide evidence of DLOM: Restricted stock studies and IPO studies.
Restricted stock issues are private placements made by public companies. The issue price is compared to the listed price. According to restricted stock studies in the US, large companies make private placements at no or minimal discount to the market price. Where as small companies, with a market capitalisation of less that $55m, offer discounts of between 35% and 91%.
