Arcosa Phantom Stock Units financial

"The Arcosa Phantom Stock Units were accrued under the Arcosa, Inc. Deferred Plan for Director Fees."

Deferred Plan for Director Fees financial

"The Arcosa Phantom Stock Units were accrued under the Arcosa, Inc. Deferred Plan for Director Fees."

A deferred plan for director fees lets a company delay paying board members their compensation until a future date or convert it into a future payment vehicle, such as cash at a later time or equity that vests over years. For investors, it matters because deferral can conserve current cash and tie directors’ rewards to long-term company performance—similar to choosing to receive part of your paycheck later to encourage long-term commitment—but it also creates future obligations that affect shareholder value and bankruptcy risk.

economic equivalent financial

"Each share of phantom stock units is the economic equivalent of one share of common stock."

settle in cash financial

"The phantom stock units settle in cash upon the reporting person's termination of services with Arcosa."
