(1) Use of transferred assets
(A) In general Any assets transferred to a health benefits account in a qualified transfer (and any income allocable thereto) shall be used only to pay qualified current retiree health liabilities (other than liabilities of key employees not taken into account under
subsection (e)(1)(D)) for the taxable year of the transfer (whether directly or through reimbursement).
(B) Amounts not used to pay for health benefits
(i) In general Any assets transferred to a health benefits account in a qualified transfer (and any income allocable thereto) which are not used as provided in subparagraph (A) shall be transferred out of the account to the transferor plan.
(ii) Tax treatment of amounts Any amount transferred out of an account under clause (i)—
(I) shall not be includible in the gross income of the employer for such taxable year, but
(C) Ordering rule For purposes of this section, any amount paid out of a health benefits account shall be treated as paid first out of the assets and income described in subparagraph (A).
(2) Requirements relating to pension benefits accruing before transfer
(A) In general The requirements of this paragraph are met if the plan provides that the accrued pension benefits of any participant or beneficiary under the plan become nonforfeitable in the same manner which would be required if the plan had terminated immediately before the qualified transfer (or in the case of a participant who separated during the 1-year period ending on the date of the transfer, immediately before such separation).
(B) Special rule for 1990 In the case of a qualified transfer described in
subsection (b)(4), the requirements of this paragraph are met with respect to any participant who separated from service during the taxable year to which such transfer relates by recomputing such participant's benefits as if subparagraph (A) had applied immediately before such separation.
(3) Minimum cost requirements
(A) In general The requirements of this paragraph are met if each group health plan or arrangement under which applicable health benefits are provided provides that the applicable employer cost for each taxable year during the cost maintenance period shall not be less than the higher of the applicable employer costs for each of the 2 taxable years immediately preceding the taxable year of the qualified transfer.
(B) Applicable employer cost For purposes of this paragraph, the term “applicable employer cost” means, with respect to any taxable year, the amount determined by dividing—
(i) the qualified current retiree health liabilities of the employer for such taxable year determined—
(II) in the case of a taxable year in which there was no qualified transfer, in the same manner as if there had been such a transfer at the end of the taxable year, by
(ii) the number of individuals to whom coverage for applicable health benefits was provided during such taxable year.
(C) Election to compute cost separately An employer may elect to have this paragraph applied separately with respect to individuals eligible for benefits under title XVIII of the Social Security Act at any time during the taxable year and with respect to individuals not so eligible.
(D) Cost maintenance period For purposes of this paragraph, the term “cost maintenance period” means the period of 5 taxable years beginning with the taxable year in which the qualified transfer occurs. If a taxable year is in two or more overlapping cost maintenance periods, this paragraph shall be applied by taking into account the highest applicable employer cost required to be provided under subparagraph (A) for such taxable year.
(E) Regulations
(i) In general The Secretary shall prescribe such regulations as may be necessary to prevent an employer who significantly reduces retiree health coverage during the cost maintenance period from being treated as satisfying the minimum cost requirement of this subsection.
(ii) Insignificant cost reductions permitted
(I) In general An eligible employer shall not be treated as failing to meet the requirements of this paragraph for any taxable year if, in lieu of any reduction of retiree health coverage permitted under the regulations prescribed under clause (i), the employer reduces applicable employer cost by an amount not in excess of the reduction in costs which would have occurred if the employer had made the maximum permissible reduction in retiree health coverage under such regulations. In applying such regulations to any subsequent taxable year, any reduction in applicable employer cost under this clause shall be treated as if it were an equivalent reduction in retiree health coverage.
(II) Eligible employer For purposes of subclause (I), an employer shall be treated as an eligible employer for any taxable year if, for the preceding taxable year, the qualified current retiree health liabilities of the employer were at least 5 percent of the gross receipts of the employer. For purposes of this subclause, the rules of paragraphs (2), (3)(B), and (3)(C) of
section 448(c) shall apply in determining the amount of an employer's gross receipts.
