To help you understand how the AFTRA Retirement Plan works, it's important for you to know the meaning of the terms defined in Retirement Plan glossary included in the current Summary Plan Description (SPD). Please note, however, that this glossary is intended to provide only a basic understanding of these important terms as they are used in the Retirement Plan. You should review the entire current Retirement Fund SPD and any subsequent Benefits Updates to more fully understand these terms and how they are applied (including various special rules and exceptions that may be relevant to you).
