32 An entity shall classify a multi-employer plan as a defined contribution plan or a
defined benefit plan under the terms of the plan (including any constructive obligation
that goes beyond the formal terms).
33 If an entity participates in a multi-employer defined benefit plan, unless paragraph 34
applies, it shall:
(a) account for its proportionate share of the defined benefit obligation, plan assets
and cost associated with the plan in the same way as for any other defined
benefit plan; and
(b) disclose the information required by paragraphs 135–148 (excluding paragraph
148(d)).
34 When sufficient information is not available to use defined benefit accounting for a
multi-employer defined benefit plan, an entity shall:
(a) account for the plan in accordance with paragraphs 51 and 52 as if it were a
defined contribution plan; and
(b) disclose the information required by paragraph 148.
35 One example of a multi-employer defined benefit plan is one where:
(a) the plan is financed on a pay-as-you-go basis: contributions are set at a level that is
expected to be sufficient to pay the benefits falling due in the same period; and future
benefits earned during the current period will be paid out of future contributions; and
(b) employees’ benefits are determined by the length of their service and the participating
entities have no realistic means of withdrawing from the plan without paying a
contribution for the benefits earned by employees up to the date of withdrawal. Such a
plan creates actuarial risk for the entity: if the ultimate cost of benefits already earned at
the end of the reporting period is more than expected, the entity will have either to
increase its contributions or to persuade employees to accept a reduction in benefits.
Therefore, such a plan is a defined benefit plan.
36 Where sufficient information is available about a multi-employer defined benefit plan, an entity
accounts for its proportionate share of the defined benefit obligation, plan assets and postemployment
cost associated with the plan in the same way as for any other defined benefit
plan. However, an entity may not be able to identify its share of the underlying financial
position and performance of the plan with sufficient reliability for accounting purposes. This
may occur if:
(a) the plan exposes the participating entities to actuarial risks associated with the current
and former employees of other entities, with the result that there is no consistent and
reliable basis for allocating the obligation, plan assets and cost to individual entities
participating in the plan; or
