PPA includes expanded disclosure rules, which require the plan to give employers and unions that request them copies of actuarial valuation reports "including any sensitivity testing" - a term which is undefined.

Does anyone have any insight as to what would be required to be disclosed?

In an October 15, 2007 letter from the National Coordinating Committee for Multiemployer Plans, Washington DC, to EBSA's Office of Regulations and Interpretations, the following definition was suggested: "'Sensitivity testing' means a report, which may be part of the regular actuarial report, reviewing the impact of future experience that deviates from the actuarial assumptions used by the plan's actuary."
