Does anyone know if a plan takes the automatic 5-yr extensions for the charge bases in the 2008 valuation, if they would be permitted to take another automatic 5-yr extension on bases created in the 2009 valuation (investment losses)

In other words, can you keep taking the 5-yr extenstion on new bases every year or is it "one and done" kind of thing?

I didn't see anything saying I can't keep taking the exentions, but then again I didn't see anything that said I could.
