Australasian investment bank Macquarie Group has posted a 43% slide in first-half profit due to heavy writedowns.
Macquarie made a profit of $A604 million for the six months to the end of September, compared to $A1.1 billion a year earlier.
The half-year profit result was hit by substantial one-off costs and write-downs of more than $A1.1 billion.
Macquarie also indicated it was heading for its first fall in annual profit in 17 years.
