I have work with a fund that has 15 different money managers. For most of them, reporting the market value at any point in time isn't an issue, but for some (real estate, hedge funds, etc) the financial consultant is telling us that getting the market value as of a date other than a calendar quarter is not possible.

So if my valuation date is May 1st, I would be using March 31st values as a proxy for April 30th for some of the investments. Is this a problem or is it something that happens all the time?

The issue came up when I asked for preliminary asset information to get an idea of the funded status before May 1st.

I guess this could be in issue in single-employer plans as well.
