Reserve Bank of Australia Annual Report – 2007 Financial Statements Note 14

Note 14 SUPERANNUATION FUNDS

Two superannuation funds are operated pursuant to the Reserve Bank Act 1959: 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 the funds’ current and future benefits is funded by member and RBA contributions and the funds’ existing asset bases. The RBA's superannuation expense in relation to the OSF and the UK Pension Scheme is included in accounting profits and shown in Note 2. Administration and other operational costs (eg 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 2006/07.

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 – Employee Benefits. The UK Pension Scheme is a defined benefit scheme.

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 2005 and for the UK Pension Scheme at 1 July 2004. 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 OSF triennial funding valuation as at 30 June 2005 was based on the Aggregate Funding method, consistent with the accounting standard for superannuation funds, AAS 25 – Financial Reporting by Superannuation Plans. Under this standard, the accrued benefits of the OSF were determined as the present 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 $64 million, as the assets of the OSF of $614 million exceeded the accrued benefits of $550 million. Subsequent to the triennial review, the OSF surplus measured on the basis of AAS 25 as at 30 June 2007 amounted to $189 million (assets of $796 million less accrued benefits of $607 million).

Consistent with the actuary's funding recommendation, the Bank increased its contributions to the OSF from January 2007 to a rate of 18.3 per cent of salaries (from 15 per cent). This represents a return to a more normal long-term funding rate after a period of a decade or more in which funding had occurred at significantly less than the long-term rate, also on actuarial advice. 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 6.25 per cent and 6.75 per cent (pre-tax) for assets for current pensions, annual salary increases of 4.0 per cent and annual pension increases of 3.5 per cent.

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 2007, measured in accordance with AAS 25, was $3 million (assets of $23 million compared with accrued benefits of $20 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 actuary's triennial valuations noted above, does not take into account that the assets held by the superannuation schemes to fund future benefits have generally 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 6.35 per cent (6.0 per cent in 2005/06), future salary increases of 4.0 per cent (4.0 per cent in 2005/06), future pension increases of 3.5 per cent (3.5 per cent in 2005/06) and an assumed return on plan assets of 8.3 per cent (7.0 per cent in 2005/06). The actual return on plan assets of the OSF for 2006/07 was 19.0 per cent (12.1 per cent in 2005/06). The assumptions used for the UK Pension Scheme were a discount rate of 5.80 per cent (5.25 per cent in 2005/06), future salary increases of 5.2 per cent (5.0 per cent in 2005/06), future pension increases of 3.2 per cent (3.0 per cent in 2005/06) and an assumed return on plan assets of 5.0 per cent (4.75 per cent in 2005/06). The actual return on plan assets of the UK Pension Scheme for 2006/07 was 3.7 per cent (4.2 per cent in 2005/06). The expected overall rates of returns 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 surpluses in the OSF. At 30 June 2007 accumulation balances in the OSF totalled $144.4 million ($113.3 million as at 30 June 2006).
