Members of defined benefit superannuation funds face risks arising from underfunding of benefits by employers. In several countries (including USA, UK, Canada and Australia) fund members have suffered significant losses.

We outline a framework for assessing the minimum funding standards and solvency legislation, pointing to potential weaknesses. The Australian solvency legislation is critically assessed, revealing some serious weaknesses which may result in loss of benefits for Australian workers and their dependants.
