The interest assumptions for performing multiemployer plan valuations following mass withdrawal under part 4281 apply to valuation dates occurring in November 2004. The interest rates for late premium payments under part 4007 and for underpayments and overpayments of single-employer plan termination liability under part 4062 and multiemployer withdrawal liability under part 4219 apply to interest accruing during the fourth quarter (October through December) of 2004.
 FOR FURTHER INFORMATION CONTACT: Harold J. Ashner, Assistant General Counsel, Office of the General Counsel, Pension Benefit Guaranty Corporation, 1200 K Street, NW., Washington, DC 20005, (202) 326-4024.

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 (the “required interest rate”) in determining a single-employer plan's variable-rate premium. Pursuant to the Pension Funding Equity Act of 2004, for premium payment years beginning in 2004 or 2005, the required interest rate is the “applicable percentage” (currently 85 percent) of the annual rate of interest determined by the Secretary of the Treasury on amounts invested conservatively in long-term investment grade corporate bonds for the month preceding the beginning of the plan year for which premiums are being paid. Thus, the required interest rate to be used in determining variable-rate premiums for premium payment years beginning in October 2004 is 4.79 percent (
                    *i.e.*, 85 percent of the 5.63 percent composite corporate bond rate for September 2004 as determined by the Treasury). The following table lists the required interest rates to be used in determining variable-rate premiums for premium payment years beginning between November 2003 and October 2004. Note that the required interest rates for premium payment years beginning in November through December 2003 were determined under the Job Creation and Worker Assistance Act of 2002, and that the required interest rates for premium payment years beginning in January through October 2004 were determined under the Pension Funding Equity Act of 2004. For premium payment years beginning in:
The required interest rate is:November 2003*

 Late Premium Payments; Underpayments and Overpayments of Single-Employer Plan Termination Liability Section 4007(b) of ERISA and § 4007.7(a) of the PBGC's regulation on Payment of Premiums (29 CFR part 4007) require the payment of interest on late premium payments at the rate established under section 6601 of the Internal Revenue Code. Similarly, § 4062.7 of the PBGC's regulation on Liability for Termination of Single-Employer Plans (29 CFR part 4062) requires that interest be charged or credited at the section 6601 rate on underpayments and overpayments of employer liability under section 4062 of ERISA. The section 6601 rate is established periodically (currently quarterly) by the Internal Revenue Service. The rate applicable to the fourth quarter (October through December) of 2004, as announced by the IRS, is 5 percent. The following table lists the late payment interest rates for premiums and employer liability for the specified time periods: From—

 Underpayments and Overpayments of Multiemployer Withdrawal Liability Section 4219.32(b) of the PBGC's regulation on Notice, Collection, and Redetermination of Withdrawal Liability (29 CFR part 4219) specifies the rate at which a multiemployer plan is to charge or credit interest on underpayments and overpayments of withdrawal liability under section 4219 of ERISA unless an applicable plan provision provides otherwise. For interest accruing during any calendar quarter, the specified rate is the average quoted prime rate on short-term commercial loans for the fifteenth day (or the next business day if the fifteenth day is not a business day) of the month preceding the beginning of the quarter, as reported by the Board of Governors of the Federal Reserve System in Statistical Release H.15 (“Selected Interest Rates”). The rate for the fourth quarter (October through December) of 2004 (
                    *i.e.*, the rate reported for September 15, 2004) is 4.50 percent. The following table lists the withdrawal liability underpayment and overpayment interest rates for the specified time periods: From—

 Multiemployer Plan Valuations Following Mass Withdrawal The PBGC's regulation on Duties of Plan Sponsor Following Mass Withdrawal (29 CFR part 4281) prescribes the use of interest assumptions under the PBGC's 
                    ( print page 61272)
                    regulation on Allocation of Assets in Single-Employer Plans (29 CFR part 4044). The interest assumptions applicable to valuation dates in November 2004 under part 4044 are contained in an amendment to part 4044 published elsewhere in today's 
                    **Federal Register**
                    . Tables showing the assumptions applicable to prior periods are codified in appendix B to 29 CFR part 4044. Issued in Washington, DC, on this 12th day of October 2004. Joseph H. Grant, Deputy Executive Director and Chief Operating Officer, Pension Benefit Guaranty Corporation.
