This post is just as much a questioning, as much as it is a comment on what I *think* to be true.
I'm not clear which pensions you are referring to, but fiscal years and therefore budgets for US, Federal, State, and municipalities are different. The US Federal government fiscal year begins/began October 1. About 80% of US States have a fiscal year which begins/began on July 1, and municipalities can differ from the home state, and even differ by department (fire, police, etc). Of course (public or private) corporate fiscal year-ends differ as well.
What I know for sure are the links between pensions at all levels of government, interest rates, and taxes.
