BC1 This Basis for Conclusions summarises the International Accounting Standards Board's considerations in reaching its conclusions on IAS 19 Employee Benefits. Individual Board members gave greater weight to some factors than to others.

BC2 The Board's predecessor, the International Accounting Standards Committee (IASC), approved IAS 19 Employee Benefits in 1998, replacing a previous version of the standard. IASC developed the revision of IAS 19 in 1998 following its consideration of the responses to its exposure draft E54 Employee Benefits published in 1996. Since that date, IASC and the Board have made the following amendments that are still relevant:

(a) In October 2000 IASC extended the definition of plan assets (see paragraphs BC178-BC190) and introduced recognition and measurement requirements for reimbursements (see paragraphs BC195-BC199).

(b) In December 2004 the Board amended the accounting for multi‑employer plans and group plans (see paragraphs BC35-BC38 and BC40-BC50).

(c) In June 2011 the Board eliminated previous options for deferred recognition of changes in the net defined benefit liability (asset), amended where those changes should be recognised, amended the disclosure requirements for defined benefit plans and multi‑employer plans, and made a number of other amendments (see paragraphs BC3-BC13).
