Industry superannuation giant Aware Super returned 10.7 cent in its default option last financial year, far outstripping the rest of the sector thanks to its relatively low office property exposure and higher global equities holdings.

The fund wrote down office towers by about 5 per cent. But this was less than the 10-15 per cent writedowns reported by rivals, amid a reckoning of the sector’s worth and regulatory warnings against inflated valuations.
