Expenses paid from Pension Trust

As part of some due diligence work, I am reviewing the invoices for a qualified pension plan that is severely underfunded for the past several years. I am seeing billing for PBGC filings and actuarial valuation work that are normal parts of plan administration and can be paid from pension assets. However, I also see some payments for annual pension meetings to discuss valuation work. Hiring an actuarial firm is one thing, but would anyone consider paying travel expenses for the actuarial firm to attend a meeting a part of plan administration? My thought is that a travel expense should be paid from the company account and not plan assets. Looking for other opinions. Thanks!

If the meeting was to fly down to the company worksite to explain the valuation, I don't see why charging the trust is a problem. It's an administrative expense, and probably allowed for in whatever engagement letter the company signed with the actuarial firm.

if there was any other business carried on at the meetings that involved plan design or corporate liability calculations, the travel expense probably need to be allocated between the company and the trust.
