Phantom Units financial
"Phantom Units granted under Long-Term Incentive Plan (includes distribution equivalent rights"
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.
distribution equivalent rights ("DER") financial
"includes distribution equivalent rights ("DER") payable in cash"
total shareholder return (TSR) financial
"based on PAA's total shareholder return (TSR) over the three-year period"
Total shareholder return (TSR) measures how much an investment in a company's stock has grown over a specific period by combining the change in the share price and all dividends paid, expressed as a percentage. Think of it like tracking the total balance of a savings jar that increases both from added cash (dividends) and a rising sticker price on the jar (share price); investors use TSR to compare how well different stocks or managers deliver real, money-in-hand returns.
distributable cash flow (DCF) financial
"based on PAA achieving cumul. distributable cash flow (DCF) per common unit"
leverage ratio financial
"if PAA's leverage ratio (long term debt to adj. EBITDA as calculated"
Leverage ratio measures how much a company relies on borrowed money compared with its own funds or assets, typically expressed as debt relative to equity or total assets. Like a homeowner with a mortgage, higher leverage can amplify returns when business is strong but also raises the chance of big losses or default if revenue falls, so investors use it to judge financial risk and resilience.
