Discussion late last week over the efficacy of the new Coalition Government's plans to abolish the Clean Energy Finance Corporation tended to centre on the obligation of the financier's directors to pursue the CEFC's legislated goals - and how to stay open for new business pending any decision by Parliament to liquidate it. In reality, a simple administrative fiat is available to achieve the policy goal.All that needs be done is to modify the CEFC's investment mandate direction.In April last year, the then Labor treasurer, Wayne Swan, directed that the Clean Energy Finance Corp target a rather low return based on "a weighted average of the five-year Australian Government bond rate" net of operating expenses. The target return was around three per cent, based on the yield on a five-year bond over the last year.Today that yield is around 3.15 per cent.The CEFC was always modest, given the government's Future Fund targets an average return of at least the consumer price index plus 4.5 per cent to 5.5 per cent. The Future Fund returned more than seven per cent over the three years to June 2013.So far the CEFC has committed around $500 million in investments, about a quarter of its budget.So, all the new treasurer, Joe Hockey, needs to do is to alter the CEFC's investment mandate to something so stiff that no energy proponent would consider the CEFC as a source of funds and would instead look to find the necessary capital in the private market.
