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 Protection Act of 2006, for premium payment years beginning in 2006 or 2007, the required interest rate is the “applicable percentage” 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 (the “premium payment year”). On February 2, 2007 (at 72 FR 4955), the Internal Revenue Service (IRS) published final regulations containing updated mortality tables for determining current liability under section 412(l)(7) of the Code and section 302(d)(7) of ERISA for plan years beginning on or after January 1, 2007. As a result, in accordance with section 4006(a)(3)(E)(iii)(II) of ERISA, the “applicable percentage” to be used in determining the required interest rate for plan years beginning in 2007 is 100 percent. The required interest rate to be used in determining variable-rate premiums for premium payment years beginning in May 2007 is 5.98 percent (
                    *i.e.*, 100 percent of the 5.98 percent composite corporate bond rate for April 2007 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 June 2006 and May 2007. For premium payment years beginning in:

 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 regulation on Allocation of Assets in Single-Employer Plans (29 CFR part 4044). The interest assumptions applicable to valuation dates in June 2007 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 10th day of May 2007. Vincent K. Snowbarger, Interim Director, Pension Benefit Guaranty Corporation.
