Short PY & Min/Max contribution under PPA?

[flosfur]

Is the Target Normal Cost prorated, especially for the Max, for short plan year?

I think not, because the TNC is the value of benefit accruing during the plan year, short or not!

I would agree with your interpretation. However, the amortization of the shortfall base would be prorated (if there is one).
