This question stems from several recent cases encountered in the practice of new-style phantom stock, as well as a related question posed by an anonymous user on Proformative (see link:https://www.proformative.com/questions/phantom-stock-plan-private-company-700-employees-05b-revenue-10m-ni）。

My core question is divided into three parts. Assume a late-stage private company (with revenue, moving toward profitability) establishes a phantom stock plan that triggers only upon a change of control (e.g., M&A, IPO, etc.). The plan stipulates that each holder of a phantom stock "unit" receives an amount equal to what preferred shareholders would receive in cash after deducting costs (but without considering the capital initially invested by preferred shareholders). For example, if a preferred shareholder nets $10 per share in an M&A event, phantom stock unit holders should also receive $10. The plan has two characteristics: first, it has a vesting period, meaning holders must satisfy vesting conditions to receive payment; second, unlike restricted stock, if a holder leaves before a change of control, they forfeit all rights and receive nothing. Essentially, this is a "bonus" paid only upon successfully driving the company to an M&A, and it never carries any equity rights nor constitutes debt.

Question 1: Tax treatment—should it be treated as ordinary compensation?

The plan is similar in nature to straight comp. Does anyone have experience treating it as capital gains rather than ordinary income through an 83(b) election or similar structure?

Question 2: Forfeiture upon departure—is it common and reasonable?

The forfeit-on-departure clause is a red flag to me. Is this arrangement common? I have indeed seen many similar cases, but given the simultaneous vesting period, the clause seems somewhat unbalanced, disadvantageous to holders.

Question 3: Accounting treatment—how to measure and recognize?

How should such plans be accounted for? There is some guidance, such as ASC 718-10-35-8, but the forfeiture issue always lingers in my mind; additionally, valuation seems difficult? If a 409A valuation is performed at the grant date, it is likely to undervalue the fair value.

Looking forward to your insights. Thanks! —Keith
