Australia's chief financial officers are preparing to expose their businesses to higher levels of risk in the year ahead, as they pursue growth opportunities. But not many will be increasing their borrowing to fund expansion.According to the latest Deloitte quarterly survey of listed company CFOs, the mood in corporate Australia is positive. CFOs said they felt more assured about the financial prospects of their companies. Seventy-nine per cent said they expected their company's revenues to grow over the next 12 months and 46 per cent said they planned to increase capital expenditure.Factors contributing to this mood include the fall of the Australian dollar, low interest rates, improvements in the US and European economies and a belief that the degree of economic uncertainty is not as great as 12 months ago.Fifty-five per cent of CFOs said it was a good time to take more risk - the first time in three years that a majority of CFOs thought so. In the third quarter of 2012 only 14 per cent thought it was a good time to take extra risk.CFOs said credit was more keenly priced than at any time since 2009 and was readily available.However, only 25 per cent said they would raise their gearing levels over the next 12 months. CFOs have access to high levels of internal funding, and this was the most attractive source of funding.Asked to list the "key fundamentals for growth", CFOs did not mention funding or banking relationships to any measurable degree.
