Australia鈥檚 sovereign wealth fund has reported above-target returns as it shifts out of cash into infrastructure and alternative assets.

The Future Fund said it produced a total return of 7.8% in 2016, while its exposure to alternative assets, including real estate, increased from 12.6% to 14.2%.

Managing director David Neal attributed the increased exposure to infrastructure to the acquisition of the Port of Melbourne.

The Future Fund was part of a QIC-led a consortium, including Canada鈥檚 OMERS and China Investment Corporation, which bought Australia鈥檚 largest container port for AUD9.7bn (鈧6.83bn) last year.

Neal said: 鈥淲e settled on the port in the last quarter.鈥

The Future Fund has also committed AUD400m to AGL Energy鈥檚 AUD2bn renewable energy fund.

Total allocation to infrastructure and timberland was AUD10bn at year-end, 7.9% of the total portfolio.

Most of that was in infrastructure, said former Australian treasurer, Peter Costello, the fund鈥檚 chairman.

Costello described the 7% allocation to infrastructure as 鈥減retty decent,鈥 adding that not many investment funds鈥 infrastructure exposure would be 鈥渢hat high鈥.

The Future Fund鈥檚 allocation to real estate was AUD7.9 billion, equivalent to 6.2% of its portfolio.

Neal said that the Future Fund had been de-risking throughout 2015 and 2016, mainly by reducing its equities investment.

He was comfortable with a 鈥渟lightly conservative鈥 position, but said: 鈥淲e are not expecting or forecasting major market dislocation.鈥

Costello, who set up the Future Fund when he was Australia鈥檚 Federal Treasurer in 2006, said that, despite the challenging global environment, the fund had met its mandated return of 4-5% above inflation rate since inception.

The fund was set up with a federal government contribution of AUD60.5bn.

With consistent annual returns of 7.8%, that initial capital had grown to AUD127.7bn by 31 December 2016.

Costello said 10-year bonds, the benchmark for investment returns, were trading at around 2%, with a real return of 1% or less, compared to an historical return of 5-6%. He said such low returns and a risk environment would continue into the future.

The Future Fund鈥檚 existing mandate was 鈥渁 proper mandate for the last 10 years鈥, but given the outlook for the investment climate, the fund鈥檚 mandate needed to be revisited for the next 10 years 鈥渁nd the government will consider this鈥.

The government has instructed the fund not to take excessive risk, but still seeks a 4.5% real return.

鈥淭hose two objectives, which we鈥檝e managed over the last 10 years, will be rubbing into each other over the next 10,鈥 said Costello.

Under the current statute, the Australian government will be able to start drawing down on the fund from 2020.
