This is NERCC's:
There is a wealth of info online, but first, call the NYCDCC & request their edition for your DC Rules regarding your Pension Beneifts and vesting requirements. It will ocver the exact same topical inofrmation, with rules applicable to the NYCDCC. If you can't get any satisfaction, you can contact EBSA.
The UBC years ago initiated the money follows the man rule, however, each DC within this alleged International Organization fights every other DC in the country as all of them have separate interests, so - say you move you inform them of the new address, the money from your prior DC will be held by them until the day you retire and they use it to shore up their own funds (Green, Yellow & Red Zone) until they have to release it, not sooner. Hardly a fair system but that is how they play games with your career & your future security. They got theirs, the hell with you. BTW, they (THE FUNDS) don;t particularly care if you ever vest, because to them, it's their money & they will keep it.
