Discounting employee benefits in accordance with AASB119


Commonwealth Bond yields are used by Local Governments when discounting employee benefits under Australian Accounting Standard AASB119 Employee Benefits.

The Reserve Bank of Australia (RBA) generally publishes yields on the 1st or 2nd business day after the applicable reporting period has ended. The Department when it republishes these yields doesn’t make any changes to RBA data, other than visual formatting.

Commonwealth Bond yields (as at the end of financial year) are published on the RBA’s website:

Australian Accounting Standard AASB119 Employee Benefits requires:

AASB 119.Aus83.1 Notwithstanding paragraph 83, in respect of not-for-profit public sector entities, post-employment benefit obligations denominated in Australian currency shall be discounted using market yields on government bonds.

AASB 119.83 The rate used to discount post-employment benefit obligations (both funded and unfunded) shall be determined by reference to market yields at the end of the reporting period on high quality corporate bonds. For currencies for which there is no deep market in such high-quality corporate bonds, the market yields (at the end of the reporting period) on government bonds denominated in that currency shall be used. The currency and term of the corporate bonds or government bonds shall be consistent with the currency and estimated term of the post-employment benefit obligations.

AASB119 also has the following features:

  • Prescribes general recognition and measurement criteria for employee benefits including wages and salaries, compensated absences, profit sharing and bonus plans, termination benefits and certain post-employment benefits.
  • Requires liabilities that arise in respect of short-term employee benefits (wages and salaries, leave entitlements and other employee benefits expected to be settled wholly within 12 months of the reporting date) to be measured at their nominal amounts.
  • Requires other long-term employee benefit liabilities (e.g. long service leave not expected to be settled wholly within 12 months after the reporting date) to be measured at present value.
  • Requires the market yields on government bonds to be used in determining the present value of other long-term employee benefit liabilities.
  • Requires disclosures to be made.

The current version of AASB 119 is available here.
