<prompt> Human: These are portions of the letters they sent. Sorry for potato quality  <response>: Heres a summary- I work in this industry.Your father appears to be a member of the Central States Teamsters Pension Plan which is probably the most well known underfunded pension plan in the country.The Pension Benefit Guarantee Corporation PBGC guarantees a portion of your fathers pension worth 35.7518.75 years 670.31month. If the Plan went insolvent, your dad would receive this amount for life or until the PBGC runs out of money.The Multiemployer Pension Reform Act, in an attempt to let pension plans save themselves rather than go insolvent, allows pension plans that meet certain criteria to cut benefits to 110 of the PBGC guaranteed amount. 110670.31 737.34. The Central States Plan is electing to use this relief to try to save itself rather than go insolvent. This obviously sucks, but could also be a very slight positive for your father. If the Plan went insolvent he could be stuck with the 670.31month or alternatively 0month if the PBGC itself were to go insolvent.
