Phantom Stock Units financial

"The Phantom Stock Units convert to BXP, Inc. ("BXP") common stock on a 1-for-1 basis."

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.

2021 Stock Incentive Plan financial

"The Phantom Stock Units are awarded under BXP's 2021 Stock Incentive Plan to non-employee directors..."

dividend equivalent rights financial

"Includes 243.58 Phantom Stock Units received pursuant to dividend equivalent rights..."

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.

measurement funds financial

"may make one or more elections to reallocate... to a deemed investment in one or more measurement funds."
