Shareholders now have greater protection under new rules designed to clamp down on misleading, 'low-ball' share offers.
New regulations which came into effect over the weekend will govern how unsolicited offers to investors can be made, said Commerce Minister Craig Foss today.
"Unsolicited or 'low-ball' offers are a predatory tactic that damages the health and confidence of our capital markets," he said.
Low-ball offers are unsolicited approaches to shareholders offering to buy their stocks, bonds and other securities.
Shareholders typically receive a letter putting pressure on them to sell their shares quickly, often with little information and using unconventional business practices.
