SUPPLEMENTARY INFORMATION: Variable-Rate Premiums Section 4006(a)(3)(E)(iii)(II) of the Employee Retirement Income Security Act of 1974 (ERISA) and § 4006.4(b)(1) of the PBGC's regulation on Premium Rates (29 CFR part 4006) prescribe use of an assumed interest rate in determining a single-employer plan's variable-rate premium. The rate is the “applicable percentage” (currently 85 percent) of the annual yield on 30-year Treasury securities for the month preceding the beginning of the plan year for which premiums are being paid (the “premium payment year”). The yield figure is reported in Federal Reserve Statistical Releases G.13 and H.15. The assumed interest rate to be used in determining variable-rate premiums for premium payment years beginning in June 2001 is 4.91 percent (
