(PBGC) settlement plans, and government contractor plans described in sectionsIRC
103(c)(2), 104(c), 104(d), 105, and 106, respectivelyofr espectively, of the Pension Protection
Act of 2006 (PPA ’06), as amended by the Preservation of Access to Care for Medicare
Beneficiaries and Pension Relief Act of 2010 (PRA 2010). In these cases, the appropriate
effective date should be specified in the adoption agreement. See the sample adoption
agreement language following this note to reviewer.
Additionally, the Cooperative and Small Employer Charity Pension Flexibility Act
amended Code §I RC 436 to allow an exemption to all plans defined under Code §I RC
414(y). However, a Cooperative and Small Employer Charity Plan that is in funding
restoration status is subject to restrictions on certain amendments increasing benefits,
adding new benefits, changing the rate of benefit accruals, or changing the rate at which
benefits become nonforfeitable (see Code §I RC 433(j)(2)).
The sample plan language reflects the requirements of the final Treas. Reg. § 1.436-1 issued
on October 15, 2009. For plan years beginning before January 1, 2010, a plan sponsor may
have operated its plan in reliance on the proposed Regulations or on Notices 2008-21 and
2008-73. If the plan’s operation in plan years beginning on or after January 1, 2008, but
before January 1, 2010, was not consistent with the sample plan language but satisfies the
rules in either the Proposed Regulations or the Final Regulations under Code § IRC 436,
or another reasonable interpretation of Code §I RC 436, the plan sponsor should specify
in the adoption agreement that the provisions of this article are effective for plan years
beginning on or after January 1, 2010, and the requirements of Code § IRC 436 are
incorporated by reference in the terms of the plan for earlier plan years beginning on or
after January 1, 2008. See the following sample adoption agreement language.)
