CHESS Depositary Interests technical

"CHESS Depositary Interests ("CDIs") held on the Australian Stock Exchange"

CHESS depositary interests are tradable certificates used on the Australian settlement system that represent ownership of underlying foreign shares held by a custodian. They let investors buy and sell foreign-listed stocks on the local exchange as if they were domestic shares, simplifying trading, dividend collection and record-keeping, though they may involve custodian fees and can alter certain direct shareholder rights and tax treatments.

CDI Ratio technical

"1 share of common stock per 12 CDIs (the "CDI Ratio")"

voting and investment control regulatory

"has voting and investment control over the reported shares"
