In a report to be released on Monday, the panel (of the Society of Actuaries) will recommend that pension actuaries provide plan boards of trustees and, ultimately, the public with the fair value of pension obligations and estimates of the annual cash outlays needed to cover them. That means pension officials would disclose something they have long resisted discussing: the total cost, in today’s dollars, of the workers’ pensions, assuming no credit for expected investment gains over the years.
