As well, investors will get a bonus share for every 25 T3 shares they retain. Investors still holding T3 shares who decide against paying the final instalment will face a default notice from Telstra along with an $82.50 administration fee. The underlying share can be sold by the trustee company in charge of the sale if the final instalment is not paid. The government raised around $15.5 billion from the final tranche of Telstra float, with 35 per cent of its stake going to institutional and retail investors and around 17 per cent being lodged with the Future Fund. A Telstra spokeswoman said the telco's market capitalisation had increased by $15 billion to $60 billion since the T3 sale.
