The objective of IAS 26 is to specify measurement and disclosure principles for the reports of retirement benefit plans. All plans should include in their reports a statement of changes in net assets available for benefits, a summary of significant accounting policies and a description of the plan and the effect of any changes in the plan during the period.
Retirement benefit plans are normally described as either defined contribution plans or defined benefit plans, each having their own distinctive characteristics. Occasionally plans exist that contain characteristics of both. Such hybrid plans are considered to be defined benefit plans for the purposes of IAS 26.
