A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The Australian Securities and Investments Commission announced the sentence on June 4, 2020 as release 20-127MR.

Wong sold 74,968 Sirtex shares for about A$2.14 million on October 26, 2016 while holding inside information about sales; the shares fell about 49 percent after a December 2016 trading update, and the sale would have fetched about A$1.12 million at the later average price.

He had pleaded guilty. The record previously showed the matter as filed and described it as an allegation.

What technique is this, and how does it work?

This action is tagged with one technique in our taxonomy. The tagging is ours: regulators charge statutory provisions, not technique names, so the mapping is an editorial judgement described in our editorial policy.

Same matter

The library links these 3 records because they appear to concern one matter: the same lead defendant, an overlapping technique tag and close filing dates, or a shared court docket or a release that cites the other. Records are listed by date filed.

This grouping is the library's, made by matching names, techniques, dates and citations when the site is built. It is not the regulator's or a court's determination that the records are one case, and it errs towards missing a link rather than making a false one.
