SYDNEY, June 17 (Reuters) – The Australian Securities Exchange will introduce major new changes that cap ​companies from issuing more than 25% ‌of their existing share capital to fund public takeovers without a shareholder vote, bowing to pressure from investors concerned about becoming diluted in corporate buyouts.

The draft ‌new ​rules published Wednesday reduce the ⁠number of shares ⁠companies in the S&P/ASX300 index can issue from 100% of their capitalisation to 25% before seeking shareholder approval.

The ASX launched a review ​last year after James Hardie was given a waiver from the stock exchange making ⁠it exempt from a ⁠shareholder vote when it issued about ​35% of its shares to fund the $8.8 billion ​takeover of AZEK.

“We have listened to the ‌market, and have  heard loud and clear the  market’s support for more  protections against share dilution in public takeovers and mergers,” said Gavin Skene, the ASX’s ⁠Acting Group Executive, Listings.

James Hardie shareholders were angered their investments were diluted by the company issuing a ⁠large number ‌of shares without seeking approval before ⁠the deal proceeded.

The building products ​company ‌chair Anne Lloyd and two directors were ​voted off ⁠the board by investors frustrated by the way the takeover was handled by the Australian-listed firm.
