Help!!!
I know what this is but have never had any involvement in administration.
As Benefit Administration how much involvement is this person expected to contribute. Should this information come from Finance/Accounting? What information is the Benefits person expected to present?

What do you mean by "involvement"?
The "FAS87 valuation" is provided by the plan's actuary. It's purpose is to provide (primarily) two pieces of information: the accounting expense for the fiscal year, and the information applicable for financial statement purposes at the end of the fiscal year. (BTW, "fiscal year" refers to the year of the plan sponsor, not the plan year.)
