Phantom Units financial
"Phantom Units granted under Long-Term Incentive Plan"
Phantom units are a form of employee compensation that mimics ownership in a company without issuing real shares: recipients receive cash or stock value tied to the company’s share price or performance when the units vest. They matter to investors because phantom units align employee incentives with shareholder value while avoiding share dilution; however, they create future cash obligations and can affect a company’s financial statements and cash flow.
Long-Term Incentive Plan financial
"Phantom Units granted under Long-Term Incentive Plan"
A long-term incentive plan is a company program that pays executives or employees with stock, options, or cash tied to multi-year performance goals, where the rewards become theirs only after meeting conditions over time. Think of it as a delayed bonus or retirement-style reward that aligns employees’ interests with shareholders by encouraging them to boost long-term value; investors watch these plans because they affect pay costs, share dilution and management incentives.
distribution equivalent rights financial
"includes distribution equivalent rights payable in cash"
exercise price or tax liability financial
