change in funding method?

[Gary]

we changed from datair using dos to datair using windows.

Would that be considered a change in valuation software, thus a change in funding method?

assuming it is a change in software, if the plan does not file a schedule r and instead files a 5500SF then does the sponsor have to approve the change in method? Schedule R item 8 requires sponsor approval, but what if there is no schedule R.

The alleged change in funding method receives automatic approval per IRS announcement 2010-3.

thanks

For Datair in particular, you have the ability to run the valuation on both systems to see if the results are the same, within acceptable limits.

But the new system has many more options, so you might need to check specific issues for plans that do not come out identical.

If you then change those options, you might have a change in method.
