The senior tranche of notes received a preliminary rating of AAA from Standard & Poor's and Fitch Ratings.
MyState Limited managing director John Gilbert said this transaction demonstrates the group’s diversified asset portfolio following the acquisition of The Rock Building Society Limited.
“The transaction is a positive step for the Conquest programme and the long-term funding of both institutions,” said Mr Gilbert.
A continued strong performance by MyState’s Australian residential mortgages, particularly the low arrears levels though the global financial crisis, and the highly diversified asset pool has attracted investors across the capital structure of the transaction, he added.
“The transaction will provide capital and funding benefits to the MyState Group and represents the continuing realisation of positive funding synergies from the merger with The Rock,” Mr Gilbert said.
Fourteen investors were involved in the transaction.
