While the news was good, it was not so good as to warrant such a fuss. As I stated, the overall return on the fund in 2003 was12.9%. Within this, equities were the real drivers of growth at 18.1%, a point to which I will return a little later. Since inception, the fund has outperformed its long-term benchmark by 9.6% due to the averaging-in investment strategy adopted by the commission, which I will also explain in detail in a moment.
The cost of social welfare and public service pensions is projected to increase dramatically in 20 years' time due to Ireland's ageing population. In 2001, the fund's establishment year, there were just over five people at work to every pensioner. By 2025, this ratio is projected to fall to three to one and by mid-century there will be fewer than two working people to each pensioner. This changing ratio is due to two factors, a decline in the birth rate and the fact that we are living longer lives.
This problem is faced by many countries. Our comparatively young population means that we have an opportunity to address the funding question through the National Pensions Reserve Fund mechanism and we have been ahead of many other countries in developing provision for the future. The increase in the number of pensioners to be supported by the working population will have profound implications for the costs of social welfare and public service pensions. It has been forecast that to maintain current levels of provision, costs will rise from about 4.5% of GNP at present to 8% of GNP in 2025, the first year the fund comes into play, to around 12.5% of GNP by 2056.
The bulk of these increased pension costs will arise in the social welfare rather than the public service area, with 80% of overall Exchequer pension expenditure likely to go to social welfare pensions in 2056. I emphasise this point because there has been a misconception to the effect that the fund will primarily benefit public servants or future generations. Nothing could be further from the truth. The bulk of the annual 1% of GNP contribution will go towards the financing of social welfare pensions, while three out of every four people now of working age are likely to benefit from the fund during their retirement. In short, every worker has a stake in the fund and an interest in its success, a fact of which I and the other commissioners are acutely aware.
Turning to how the fund operates, members will be aware that the National Pensions Reserve Fund Act provides for an annual Exchequer contribution of 1% of GNP to the fund. No money can be drawn down before 2025 and from then on drawdowns will continue until at least 2055, in accordance with ministerial rules related to the growth of the percentage of people aged over 65 in the population.
The commission which controls and manages the fund is independent of Government in the exercise of its functions, which include the implementation of the fund's investment mandate. This mandate requires that the fund operate on commercial lines so as to secure the best possible financial return subject to prudent risk management. The NTMA acts as the manager of the fund and the commission performs its functions through the NTMA. Essentially, the fund is structured in the same way as a private pension fund, with the aim of achieving the returns that such funds earn and the commission acts in a manner similar to private pension fund trustees.
While the commissioners determine and implement the National Pensions Reserve Fund's investment strategy, we decided at an early stage to outsource the detailed tactical or day-to-day investment decisions to specialist investment management institutions. Basically, we set the boundaries and parameters within which investments are made.
Strategic asset allocation typically accounts for 90% of returns over the life of an investment. It follows, therefore, that this is the key decision for the commission and to assist us in making it we retained Mercer, the international investment consultants, to advise on an appropriate long-term strategic benchmark. In June 2001, the commissioners considered a range of possible portfolios with different risk to reward trade-offs. The one chosen, because it offered the most attractive balance between risk and reward, was an 80-20 equity and other real assets to bond split, with a 50-50 split between eurozone and non-eurozone equities. It was recognised in setting up the fund that, given its size, Irish equities would never represent a significant holding.
There has been considerable debate around the fund's apparently heavy weighting in equities, no doubt fuelled by the market's poor performance from 2000 to 2002. I referred earlier to the role of equities in the fund. Several other points need to be considered. Equities have historically outperformed other asset classes. This extra return is known as the equity risk premium and compensates the investor for the increased risk of investment in equities as opposed to a more predictable asset classes such as bonds. The commission's investment strategy is based on a conservative equity risk premium assumption of 3% per annum.
Much of the risk associated with equities is the volatility of returns from year to year which is smoothed out in the longer term. As the fund will not have to make significant disbursements until the 2030s it can afford to bear this volatility in anticipation of the increased return which equity investment will provide.
Over the timeframe in which the commission is operating, equities must outperform bonds because investors must be rewarded for buying riskier assets. Otherwise the entire free enterprise system would collapse as there would be no adequate rewards for risk-taking and no incentive to invest in businesses. In short, the fund's equity weighting is driven by its long-term investment timeframe and the commission's statutory remit of securing the optimal financial return subject to prudent risk management.
The NTMA carried out a truly global search under EU rules for managers to run the investments according to the strategy agreed on by the Commission, reviewing 574 expressions of interest, evaluating 178 detailed submissions, interviewing 50 managers and finally appointing 14. Our fee negotiations included securing best or "favoured nation" terms. The NTMA has put in place state-of-the-art performance measurement, attribution and risk management systems to monitor the performance of the managers and to ensure that the risk to the fund remains within the limits set by the commission.
Fund managers are formally reviewed every six months by the NTMA on behalf of the commission. Full reports of these review meetings are made to the commission along with a recommendation for any action which the NTMA might consider necessary.
The next step was to start investing. Upon establishment the fund received €6.515 billion comprising the net receipts of the Eircom flotation and 1% of GNP contributions for 1999 and 2000 plus interest earned on these amounts. The commission was then faced with a decision; whether to commit funds to the markets in one fell swoop or whether to average in over time.
Despite widespread expectations of a US-led global recovery in early 2002, the commission decided that the economic and financial markets outlook was not certain. Therefore, we pursued an averaging-in approach which would reduce the fund's market entry risk by spreading its market entry over time. This enabled the commission to delay its investment strategy as market conditions deteriorated and to mitigate the worst effects of the bear market. Indeed, the fund is still not fully invested. It is currently invested 75% in equities compared with the long-term strategic benchmark allocation of 80% equities. We have already covered the 2003 performance and in 2003 we increased the equity holdings substantially while leaving the amount committed to bonds unchanged.
With the strategic investment strategy in place and the fund's core managers selected and funded, the commission has been considering additional asset classes in its continuing effort to maximise fund returns. We have approved new mandates for small capitalisation equities and corporate bonds and these are currently out to tender. At the commission's request, the NTMA is currently working on business entry plans for investment in property and private equity.
The commission is also keen to access PPP investments where the risk-return characteristics are competitive with other investments and satisfy the fund's statutory commercial investment mandate. A €200 million preliminary allocation has been made available in this area.
My introductory remarks have been deliberately brief as I know that we will explore the issues in greater detail in the course of questioning, but I hope they have provided a useful overview of the commission's investment strategy and have given you a flavour of the work we and the NTMA undertake.
I emphasise that the fund must be looked at from a long-term perspective. Short-termism, which focuses excessively on current performance or on flavour-of-the-month asset classes, will undermine the successful management of the fund. I am confident that the long-term strategic perspective adopted by the commission combined with proper risk management systems and clear manager selection and review processes will ensure that the fund will meet its overall goal of proper pension provision for all those workers who, through their taxes, are contributing to the fund and are its ultimate stakeholders.
