Cash Settled Restricted Stock Units financial

"Cash Settled Restricted Stock Units"

Cash-settled restricted stock units are employee compensation promises that mirror the value of company shares but pay out in cash instead of delivering actual stock once the units vest. Think of them as a future paycheck tied to the company’s share price that is paid after time or performance conditions are met. Investors watch them because they create future cash obligations for the company and avoid share dilution, both of which can affect earnings, cash flow and per-share metrics.
