*Critical status* has the same meaning as the term has under section 305(b)(2) of ERISA and section 432(b)(2) of the Code, and includes “critical and declining status” as defined in section 305(b)(6) of ERISA and section 432(b)(6) of the Code.
*De minimis merger* is defined in § 4231.7(b).
*De minimis transfer* is defined in § 4231.7(c).

*Facilitated merger* means a merger of two or more multiemployer plans facilitated by PBGC under section 4231(e) of ERISA, including a merger that is facilitated with financial assistance under section 4231(e)(2) of ERISA.
*Fair market value of assets* has the same meaning as the term has for minimum funding purposes under section 304 of ERISA and section 431 of the Code.
*Financial assistance* means periodic or lump sum financial assistance payments from PBGC under section 4261 of ERISA.
*Financial assistance merger* means a merger facilitated by PBGC for which PBGC provides financial assistance (within the meaning of section 4261 of ERISA) under section 4231(e)(2) of ERISA.

*Merged plan* means a plan that is the result of the merger of two or more multiemployer plans.
*Merger* means the combining of two or more plans into a single plan. For example, a consolidation of two plans into a new plan is a merger.
*Significantly affected plan* means a plan that— ( 1 ) Transfers assets that equal or exceed 15 percent of its assets before the transfer,
( 2 ) Receives a transfer of unfunded accrued benefits that equal or exceed 15 percent of its assets before the transfer,
( 3 ) Is created by a spinoff from another plan, or

*Transfer* and *transfer of assets or liabilities* mean a diminution of assets or liabilities with respect to one plan and the acquisition of these assets or the assumption of these liabilities by another plan or plans (including a plan that did not exist prior to the transfer).

In addition, the shifting of assets between several funding media used for a single plan (such as between trusts, between annuity contracts, or between trusts and annuity contracts) is not a transfer of assets or liabilities.
*Unfunded accrued benefits* means the excess of the present value of a plan's accrued benefits over the plan's fair market value of assets, determined on the basis of the actuarial valuation required under § 4231.5.
