The Discount Stack
You are valuing a 15% interest in Ridgeway Holdings, a family-owned holding company whose sole asset is a 100% interest in an operating subsidiary. The holding company has no employees, no debt, and distributes nothing; all cash is retained in the subsidiary. You have concluded a control-basis enterprise value for the subsidiary of $50 million. The 15% interest has no board seat, no distribution rights, and is subject to a buy-sell that prices transfers at 'fair market value as determined by an independent appraiser.' A colleague proposes: apply a 30% control premium to the subsidiary value, then a 20% minority discount, then a 25% marketability discount, then a 10% holding-company discount 'for the layer.'
1. Critique the proposed discount stack. Identify each error and the correct treatment.

The stack is internally contradictory and double counts.
- Control premium then minority discount. You already have a control-basis value. Adding a control premium and then stripping control back out is circular; at best the two offset, at worst they double count. Choose one level of value and stay consistent.
- Holding-company 'layer' discount. A holding company whose sole asset is a controlling interest in an operating subsidiary does not automatically warrant a separate discount. Any discount must be justified by actual frictions (e.g., trapped cash, tax leakage on upstreaming, structural subordination). A blanket 10% 'for the layer' is unsupported.
- Marketability discount on top of a buy-sell. The buy-sell provides a mechanism (independent appraisal at FMV), which affects liquidity; the DLOM must reflect that mechanism, not ignore it.
- Compounding. Applying discounts multiplicatively to an already-adjusted base magnifies the effect; each must be independently supported and not overlap.
Correct approach: start from the appropriate level of value for a 15% non-controlling interest, apply only supported adjustments, and avoid stacking.
2. Given the facts, what level of value is appropriate, and how would you build to the 15% interest?
Read the worked answer
Because the interest is non-controlling with no distribution rights and no board seat, the value should reflect a minority, non-marketable position - but built consistently.
Path:
- Start from the subsidiary's control-basis enterprise value ($50M) only as a reference; convert to a minority-basis value, either by (a) discounting the control value for lack of control using empirical minority-interest evidence, or (b) valuing the minority cash flows directly (which here are effectively zero distributions, a critical fact).
- Bridge to equity (subtract debt, add cash) at the subsidiary and then at the holding company, watching for trapped cash and tax leakage on upstreaming.
- Apply the 15% pro rata to the equity value.
- Apply a DLOM supported by evidence, explicitly considering the buy-sell appraisal mechanism (which provides a periodic liquidity path and may reduce the discount).
- Do not add a separate holding-company discount unless you can quantify a specific friction.
Because distributions are zero, the minority holder's economic position is weak - that fact should be reflected in the lack-of-control analysis, not invented as a 'layer' discount.
3. The buy-sell says transfers are priced at 'fair market value as determined by an independent appraiser.' How does this clause affect your conclusion and your report?
Read the worked answer
The clause is a contractual price mechanism that can override a purely theoretical FMV. Two consequences:
- Standard of value alignment. The buy-sell invokes fair market value; your analysis should be consistent with that standard and disclose that the governing agreement points to FMV. If the parties intend the appraiser's FMV to govern, your conclusion should be framed accordingly.
- Liquidity and DLOM. The existence of a defined appraisal-and-transfer mechanism is a liquidity feature. It does not guarantee a sale, but it is relevant evidence that may reduce the marketability discount relative to an interest with no exit path. Address it explicitly rather than ignoring it.
In the report:
- Quote the clause and explain its effect on level of value and DLOM.
- Note that the buy-sell may also constrain to whom the interest can be sold (ROFR-type rights), which affects marketability.
- Recommend legal review of the clause's interpretation, since appraisal disputes often turn on it.
Do not treat the clause as irrelevant; it is a central fact.
