MPPAA (Multiemployer Pension Plan Amendments Act)
Definition
A 1980 federal law that amended ERISA to impose withdrawal liability on employers leaving multiemployer pension plans. Before the MPPAA, employers could leave plans without financial consequence, threatening the plans' solvency. The Act created the framework for calculating, assessing, and collecting withdrawal liability that is at issue in this case.
Examples
- •The petitioners argued that the MPPAA was not designed to create fact-bound, expensive-to-litigate controversies over when actuarial assumptions can be selected.
