Source: Internal Revenue Service Form 5500 Series Filings for single-employer
plans. Data for plan years prior to 1999 include only plans with 100 or more participants.
Estimates for 2000 reported last year have been updated.
Due to rounding of individual items, numbers may not add up across columns and
percentages may not add up to 100 percent.
Vested liabilities have been adjusted to an interest rate that, along with an
assumed mortality table, reflects the cost to purchase an annuity at the beginning
of the relevant year.
The assumed mortality table was UP-84 for 1990-1992 and GAM-83 for 1993-2001.
