The Commonwealth Bank has been assigned an AAA long-term rating to two series of its mortgage-covered bonds, reflecting the credit strength of the major.
In assigning the rating to CBA’s Series 50 and Series 51 bonds, Moody’s Investors Service said the credit quality of the assets backing the covered bonds was a significant factor.
“The covered bonds are backed by Australian residential mortgage loans. The collateral score for the cover pool is 4.00 per cent,” he said.
Moody’s said the legal framework of CBA’s mortgage-covered bond program, as well as the cover pool’s exposure to market risk – which is 16.46 per cent – were also taken into account.
“As at 31 December 2015, the total value of the assets included in the cover pool is $29.1 billion, comprising $26.0 billion in residential mortgage loans and $3.1 billion in substitute assets,” it said.
“The residential mortgage loans have a weighted-average (WA) seasoning of 56.5 months and a WA current unindexed loan-to-value ratio of 55.7 per cent.”
Moody’s said its rating addresses the expected loss posed to investors, which is 19.1 per cent for the cover pool.
The ratings agency added that a change in the level of the covered bond “anchor” – the probability that an issuer will cease making payments under the covered bonds – could lead to a downgrade in the rating of the covered bonds.
