Reserve Bank of Australia Annual Report – 2013 Financial Statements Note 14 – Superannuation Funds

The Reserve Bank administers two superannuation funds: the Reserve Bank of Australia Officers' Superannuation Fund (OSF) and the Reserve Bank of Australia UK Pension Scheme. A small part of the assets of the OSF is held by the RBA as nominee for the trustees of the OSF; such assets are not included in the RBA's financial statements. Payment of these superannuation funds' current and future benefits is funded by member and RBA contributions and the funds' existing asset bases. The RBA's superannuation expenses in relation to the OSF and the UK Pension Scheme are included in accounting profits and shown in Note 2. Administration and other operational costs (e.g. salaries, overheads, legal costs and valuation fees) incurred by the RBA for superannuation arrangements are also included in Note 2. There were no other related party transactions between the RBA and the funds during 2012/13.

The OSF is a hybrid fund. Most members receive a Bank-funded defined benefit in accordance with the rules of the fund; other member benefits include unitised defined contribution accumulation balances, which comprise the RBA's productivity and superannuation guarantee contributions and members' personal contributions, plus earnings on these contributions. The OSF is classified as a single-employer plan for the purposes of AASB 119. The UK Pension Scheme is a defined benefit scheme.

Two disclosure standards are relevant for superannuation funds: AAS 25 – Financial Reporting by Superannuation Plans and AASB 119. Superannuation funds themselves report their financial position on the basis of AAS 25, which is also the basis for making assessments about the adequacy of funding arrangements to meet future obligations. Entities which sponsor superannuation funds, typically the employer entity, report for their purposes on the basis of AASB 119. Differences of approach between AAS 25 and AASB 119 result in different measures of the financial position of the same superannuation fund. Disclosures on these standards are discussed further below.

Funding valuation

Full independent actuarial valuations of the OSF and UK Pension Scheme are conducted every three years to determine funding for these schemes. The most recent funding valuation of the OSF was at 30 June 2011 and for the UK Pension Scheme at 30 June 2010. At the most recent valuations, the actuaries indicated that, on the basis of accrued benefits, both funds were in surplus and that the funds were in a satisfactory financial position. The next triennial funding valuation for the OSF for 30 June 2014 will be undertaken early in 2014/15 and that for the UK Pension Scheme for 30 June 2013 will be undertaken during 2013/14.

The OSF triennial funding valuation as at 30 June 2011 was based on the Attained Age Funding method, consistent with the accounting standard for superannuation funds, AAS 25. Under this standard, the accrued benefits of the OSF were determined as the value of the future benefits payable to members (allowing for future salary increases), discounted using the expected rate of return on the assets held to fund these benefits. At the time of the triennial review, the surplus of the OSF on this measure was $57.8 million, as the assets of the OSF of $915.5 million exceeded the accrued benefits of $857.7 million. The main financial assumptions in the triennial valuation were that the annual post-tax rate of return on assets for benefits of active members was 7.0 per cent, that for assets for current pensions was 7.5 per cent (pre-tax), with annual salary increases of 4.0 per cent and annual pension increases of 3.5 per cent. Subsequent to the triennial review, the OSF surplus measured on the basis of AAS 25 as at 30 June 2013 amounted to $59.6 million (assets of $1,033.8 million less accrued benefits of $974.2 million).

Consistent with the actuaries' funding recommendation, the RBA maintained its contribution rate to the OSF defined benefit at 18.3 per cent of salaries in 2012/13.

The triennial funding valuation for the UK Pension Scheme was based on the Attained Age method. The surplus of the UK Pension Scheme as at 30 June 2013, measured in accordance with AAS 25, was $1.4 million (assets of $19.6 million compared with accrued benefits of $18.2 million).

Accounting valuation

For financial statement purposes, the financial positions of the superannuation schemes are valued in accordance with AASB 119. Under AASB 119, accrued benefits are determined by discounting future benefits payable to current fund members at the yield on government bonds of similar maturity on the reporting date. The approach under AASB 119, in contrast with the results of the actuaries' triennial valuations noted above, does not take into account that the assets held by these superannuation schemes to fund future benefits have over time earned a higher rate of return on average than government bonds.

The principal actuarial assumptions for the AASB 119 valuation used in the case of the OSF were a discount rate of 4.7 per cent (3.9 per cent in 2011/12), future salary increases of 3.25 per cent (3.5 per cent in 2011/12), future pension increases of 3.25 per cent (3.5 per cent in 2011/12) and an assumed return on plan assets of 7.1 per cent (8.5 per cent in 2011/12). The discount rate increased over 2012/13 reflecting the movement in yields on Australian Government bonds. The actual return on plan assets of the OSF for 2012/13 was 12.7 per cent (2.4 per cent in 2011/12). The assumptions used for the UK Pension Scheme were a discount rate of 4.3 per cent (4.25 per cent in 2011/12), future salary increases of 5.4 per cent (4.95 per cent in 2011/12), future pension increases of 3.4 per cent (2.95 per cent in 2011/12) and an assumed return on plan assets of 3.14 per cent (2.42 per cent in 2011/12). The actual return on plan assets of the UK Pension Scheme for 2012/13 was 4.3 per cent (21.2 per cent in 2011/12). The expected overall rates of return are based on the actuaries' models of returns for major asset classes and reflect the historic rates of return and volatility for each class and correlations across asset classes.

Details of the funds are as shown on the following pages. In the case of the OSF, these details relate only to the defined benefit component of the fund; defined contribution accumulation balances, on which the Bank has no actuarial risk, are excluded. This has no effect on the measurement of the financial position of the OSF. At 30 June 2013, accumulation balances in the OSF totalled $206.7 million ($176.0 million as at 30 June 2012).
