The date on which you were first hired in a benefit-eligible position will determine your membership in the Closed Plan, Year 2000 or 2011 Tier.
If you were hired before July 1, 2000, and remained continuously employed until becoming vested, you are a member of the Closed Plan. Closed Plan members have the option of retiring under the Closed Plan or the Year 2000 Plan.
Year 2000 Plan
If you were hired on or after July 1, 2000, but before January 1, 2011, you are a member of the Year 2000 Plan. You are also a member of the Year 2000 Plan if you left the Closed Plan before becoming vested.
If you were hired for the first time on or after January 1, 2011, you are a member of the 2011 Tier.
