Phantom Stock financial

"Balance includes multiple phantom stock grants, phantom stock accruals and previously accrued dividend equivalents."

A phantom stock is a form of compensation that gives employees or executives the benefits of stock ownership, such as the increase in stock value, without actually giving them real shares. It acts like a promise to pay the employee the equivalent value of company stock later, often as a bonus or incentive. This allows companies to motivate and reward staff without diluting ownership or transferring actual shares.

Dividend equivalent rights financial

"Dividend equivalent rights accrued to previously granted phantom stock awards under the Amended and Restated 2002 Equity Compensation Plan of EnPro Industries, Inc."

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

Deferred Compensation Plan for Non-Employee Directors financial

"Dividend equivalent rights accrued to previously acquired phantom stock under the Deferred Compensation Plan for Non-Employee Directors (as amended and restated) of EnPro Industries, Inc."

Equity Compensation Plan financial

"Dividend equivalent rights accrued to previously granted phantom stock awards under the Amended and Restated 2002 Equity Compensation Plan of EnPro Industries, Inc."

A plan by which a company gives employees, directors or contractors ownership or the right to buy ownership in the company through stock, options or similar awards — think of promising slices of the company pie as part of someone's pay. It matters to investors because these awards can change the number of shares outstanding, affect reported profits and influence management’s decisions; large or generous plans can dilute existing holders and alter incentives over time.
