Largest insto holder of ISX allegedly marks down carrying value by 50%

According to the AFR, the largest insto holder of ISX has marked down its carrying value of their investment to 53.5c/share
I am intrigued by this and was wondering if anyone owns units in LHC to verify this information

2 schools of thought

1. They are not as confident in their holding as they were previously and are being prudent with their carrying value of the investment.

2. They are punishing anyone who is thinking about redeeming their units with such a savage writedown of their largest investment.
Possibly a way of preventing redemptions before the stock trades again
