Agreed. As I said I know nothing with regards to the MM&P plans. When I started with the MEBA the vesting period for the Money Purchase was 5 years. That has changed.
From MEBA Plans:
“Vesting” means you have a non-forfeitable interest in your account. In other words, your account balance belongs to you and it cannot be taken away. In general, you will be vested when you earn three Years of Vesting Credit. (You will also be vested when you reach your Normal Retirement Age, if that occurs before you earn three Years of Vesting Credit and are in Covered Employment.)…You earn one Year of Vesting Credit for each calendar year in which you complete 125 Days of Service. Generally, a Day of Service means a day worked in Covered Employment.
Basically the MEBA’s Money Purchase is in a sense a 401K that are employer only contributions per union agreement. Their “401K” is purely your contributions. Two separate but similar plans in that you can direct the investments from a list of options.
