PHANTOM STOCK UNITS financial
"Each phantom stock unit is the economic equivalent of one share"
Phantom stock units are company promises that pay a cash or stock-equivalent award tied to the firm’s share price or value growth, but they do not issue actual shares. Think of them as a bonus check that moves with the stock like a mirror rather than handing over an ownership slice. Investors care because these awards can affect a company’s future cash obligations, executive incentives and reported expenses without causing share dilution.

FAQ

What insider transaction did MTX director Marc E. Robinson report?

Marc E. Robinson reported receiving 40.992 phantom stock units as a grant. These units are part of his non-employee director compensation and are economically tied to Minerals Technologies Inc. common stock, but are settled in cash at the end of his board service.

What are phantom stock units in the Minerals Technologies (MTX) filing?

Phantom stock units are cash-settled awards whose value tracks common stock. In this case, each unit is the economic equivalent of one MTX share, but the director receives cash, not shares, upon termination of board service under the specified plan.

How many phantom stock units does Marc E. Robinson hold after this MTX grant?

After the 40.992-unit grant, Marc E. Robinson holds 26,914.581 phantom stock units. This total reflects his accumulated director compensation under the company’s Non-Funded Deferred Compensation and Unit Award Plan for Non-Employee Directors, all to be settled in cash later.

Does the MTX Form 4 show an open-market buy or sell of stock?

No, the Form 4 shows a compensation grant, not an open-market trade. Robinson acquired 40.992 phantom stock units with a zero exercise price, awarded under a deferred compensation plan and settled in cash rather than through purchasing or selling MTX shares on the market.

When will the MTX phantom stock units reported by Marc E. Robinson be settled?

The phantom stock units will be settled in cash upon Robinson’s termination of service as a director. Until then, they function as deferred compensation whose value mirrors MTX common stock performance, as defined in the company’s non-funded deferred compensation and unit award plan.
