Schools with endowments in the small to medium range (say, $2 million to $50 million) should charge their investment committees with studying how their endowments might fare with more active investment oversight, rather than the passive investment policies that so many of these endowments follow.
It's safe to say that The Great Recession had an effect on those schools with passively-managed endowments. Witness the schools that found themselves facing temporarily frozen assets--the ones that were supposed to be liquid. Given the spectacular performance of the markets in the lead-up to Fall 2008, most passively-managed endowments had low liquidity ratios...a real danger for those schools that must have an endowment draw to make the operational budget work properly.
When a school with a $15 million operating budget, 12-15% of which stems from endowment draw, discovers that its endowment liquidity has been compromised, one can imagine the panic which ensues.
Lesson #1 -- increase liquidity levels in your endowment.
Lesson #2 -- encourage more active management of your endowment; be sure that your portfolio manager(s) will be able to sell, reallocate (and so forth) with relative ease, rather than locking you into strict rules about when assets can or can't be sold, etc. Ongoing reallocation is a strategy to be embraced, from here on out.
There is a place for passive portfolio management, but that place is not for independent schools, as we must go out of our way to maintain inter-generational equity for our students and families. Active portfolio management will help us ensure that, by always questioning market trends.
Not unlike our university counterparts, we will have to become much better at managing our endowments.
