There are massive pension contributions that will help shore up critical funds (such as the NE Teamsters Fund) over the life of the supplement that are contingent on the supplement being passed on the first round.
This was UPS' response to 17/21 supplements being voted down last time and holding up the Master, but I think it's going to have a completely opposite effect wherein the master goes down in flames but the supplements with extra pension money sail through.
The NE Teamster's fund is currently underfunded by 1.6 billion, I believe that UPS paid out of it in 2012 (1.2 Billion) and created a Hybrid Plan similar to what they did in the Central back in 2008. Your liability issue is fixable and you should vote your Supplement in if it is a plus.
The remaining problem would be the Massive Central with it's 17.2 billion future liabilities. The PBGC federal insurance program is projected to run out of funds in 2025..The Central is projected to collapse around the same time or sooner.
Currently the markets are going bananas just look at your 401k plan. All pension trusts are invested in the markets and other securities if this trend continues it will help every pension plan nationwide. Even with that the Central is still in a "Dead Man Walking" situation, unless somehow the Feds can figure out a deal.
Nobody (the Union, UPS and the PBGC) wants to be holding the bag and being responsible, it is that big of an issue and problem..
