ING Bank (Australia) is marketing a series of notes to raise $A460 million via what is to be known as the IDOL 2016-1 Trust. These notes are backed by fully verified ("full doc") Australian prime residential mortgages. Preliminary ratings have been assigned by Moody's Investors Service as: Class A $460.0 million Notes, (P)Aaa (sf); $15.0 million Class AB; and $25.0 million Class B Notes that are not rated by Moody's.A pre-sale note from Moody's disclosed that all loans in the portfolio benefit from Lenders Mortgage Insurance policies, covering losses up to 100 per cent of the principal amount, the accrued interest of each loan and reasonable expenses involved in enforcing the mortgage.All loans in the pool were originated with full income verification.And while the portfolio "is geographically well diversified due to ING's wide distribution network", noted Moody's, the portfolio "exhibits origination vintage concentration."That is, just under 80 per cent of mortgages were originated during 2014 and 2015.
