New DB plan effective 4/1/2000 with 9 month plan year, switching to calendar year 2nd year on. Plan sponsor is on Calendar tax year.
For section 412 minimum, charges & credits are prorated for a short plan year. I could not find such a requirement (or restriction) for Section 404 maximum, which implies that full Normal cost etc can be deducted!
Any one disagree, and if so why?
