Dividend Equivalent Rights financial

"The dividend equivalent rights accrued on four restricted stock unit grants"

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.

restricted stock unit financial

"accrued on four restricted stock unit grants of which the reporting person has elected to defer receipt"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

contingent right financial

"Each RSU and DER represent a contingent right to receive one share of BWXT common stock"

deferral election financial

"In accordance with the deferral election, the DERs will be delivered to the reporting person proportionately"
