XR = ex rights issue..per asx

XR first displays for a security from the morning of the Ex Rights date (generally four business days before the record date) and remains until the close of business on the application's close date. Trading in securities displaying XR on ITS does not entitle the holder to receive securities in the Rights Issue. For more information refer to the description of Cum Rights. All orders are purged at the end of the trading day prior to the security being quoted on an XR basis.
