The number of company de-listings on the Australian Securities Exchange (ASX) has continued to rise, with 20 companies delisting in the last financial quarter this year, according to the ASX Markets Supervision report. Only three new companies were listed in the last quarter, the lowest number in over a year.

Takeovers, mergers and share redemptions were responsible for the number of delistings on the market.

There were 14 open enquiries about insider trading at the end of June, with 12 referred to the Australia Securities and Investments Commission. The referrals could partly be due to the increase in delistings and takeovers during the month, according to the report.

The ASX had five open enquiries relating to market manipulation, one enquiry in relation to trade reporting and one in relation to disorderly markets.

There were 12 matters received by the disciplinary and appeal tribunal during the fourth quarter, a jump of five from the previous quarter, with 18 disciplinary matters ongoing.
