Discounting of Prior Year Unpaid Minimum Required Contribution

[stbennet]

2009 Plan Year Minimum Required Contribution goes unpaid. There are no quarterly installments are required in 2009.

There are quarterly installments required in 2010.

I understand that all payments have to be applied to the 2009 unpaid minimum first. I'm confused as to whether I'm just using the 2009 effective rate, or if I need to add the 5% penalty at any point.

Any advice is appreciated.

it seems only the 2009 eff rate to discount to 2009 val date.
