BUT the accounting does not include the Future Fund assets which was created specifically for this issue. As at 31 March 2013 the value of the Fund's assets was $85.17 billion.
Consequently, contrary to Molyneux's comment, the "actual" funding gap (in NPV terms) is currently closer to $60 billion. Complicating matters, based on future returns/growth etc in the Future Fund the actuary reckons the asset level needed to satisfy all of the future unfunded liabilities (called the Target Asset Level) is actually only $115.2 - hence the liabilities could (hopefully) be met if the Future Fund received an asset boost of approximately $30 billion.
