Class A Units technical

"30,000 Class A Units of Plains AAP, L.P."

Class A units are a specific type of ownership stake in a company, fund, trust, or partnership that carries a defined set of rights—often different voting power, dividend priority, or fee arrangements—distinct from other classes of units. For investors they matter because those differences affect control, income and potential returns; think of two neighbors in the same building where one has a bigger say in decisions or a larger share of rental income.

limited partnership agreement technical

"Pursuant to the limited partnership agreement of AAP"

A limited partnership agreement is the legal rulebook that sets out how a limited partnership is run, naming who manages the business, how profits and losses are split, and what rights and responsibilities each partner has. For investors, it matters because it defines who makes decisions, how much liability they carry, how and when they can get their money back, and how returns are distributed—like a household budget and authority chart for a shared venture.

one-for-one basis technical

"redeemed for common units ... on a one-for-one basis"
