When actuaries do forecasting for defined benefit plans,
they do not look at one set of assumptions; they model multiple scenarios. If
the DB plan sponsor is risk-averse, it would look at the poorer outcomes and
hedge against them. The same can be done with DC planning models.
Federal data collection efforts to date have captured
little information on retirement accounts holding unconventional assets—such as
real estate, precious metals, private equity, and virtual currency.
