Key Terms

3 terms

restricted stock units financial

"Includes directly owned shares, restricted stock units and dividend equivalent units."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

dividend equivalent units financial

"Includes directly owned shares, restricted stock units and dividend equivalent units."

Dividend equivalent units are bookkeeping credits that mirror cash dividends paid on actual shares, granted to holders of stock-based awards such as restricted stock units or deferred compensation. They matter to investors because they increase a company’s reported employee compensation cost and can lead to issuance of more shares or cash payouts over time, similar to extra pay linked to ownership that affects shareholder dilution and corporate cash flow.
