INFORMATION
.01 Section 412 of the Code provides minimum funding requirements for defined benefit pension plans. Section 430, which was added by the Pension Protection Act of 2006, Pub. L. No. 109–280, 120 Stat. 780 (“PPA ’06”), specifies the minimum funding requirements for defined benefit plans other than multiemployer plans pursuant to § 412 and is generally effective for plan years beginning on or after January 1, 2008. Section 430(h)(3)(A) sets forth rules regarding the use of generally applicable mortality tables for purposes of § 430. Section 430(h)(3)(C) and § 303(h)(3)(C) of ERISA provide that the Secretary of the Treasury may approve substitute mortality tables to be used in determining any present value or making any computation under those sections for a period not to exceed ten years. Mortality tables meet the requirements for substitute mortality tables if the pension plan has a sufficient number of plan participants and the plan has been maintained for a sufficient period of time in order to have credible mortality experience, and such tables reflect the actual experience of the plan and projected trends in general mortality experience of participants in pension plans. Except as provided by the Secretary, a plan sponsor cannot use substitute mortality tables for any plan unless substitute mortality tables are established and used for each other plan subject to § 430 of the Code that is maintained by the plan sponsor and the plan sponsor’s controlled group.
.02 Section 1.430(h)(3)–1 of the Income Tax Regulations, which sets forth rules regarding the use of generally applicable mortality tables for purposes of § 430, and § 1.430(h)(3)–2, which sets forth rules for the use of substitute mortality tables under § 430(h)(3)(C), were published in the Federal Register in proposed form on May 29, 2007. Rev. Proc. 2007–37 was issued to provide procedures under which sponsors of eligible plans could request and obtain approval for plan-specific mortality tables in accordance with proposed regulation § 1.430(h)(3)–2.

The signature of an individual with a power of attorney will not suffice for the declaration. See paragraph (13) of subsection 9.02 of Rev. Proc. 2008–4.
(3) Because a request for the use of substitute mortality tables constitutes a request for a ruling, compliance with § 6110 of the Code is also required. Section 601.201 of the Statement of Procedural Rules sets forth the requirements applicable to requests for rulings and determination letters which are subject to § 6110. Section 601.201(e) furnishes specific instructions to applicants.
