The Plan includes an auto-enrollment provision for newly-eligible employees unless they affirmatively elect not to participate in the Plan. Automatically enrolled Members have their deferral rate set at a percentage of eligible compensation as defined in the plan document and their contributions are invested in a qualified default investment alternative (“QDIA”) until changed by the Members. The current QDIA for the Plan is the applicable custom target date fund.
