RE:RE:RE:RE:InsidersQTRH website. Investor Resources - FAQs. Been that for years. I recently confirmed it's still in place:
Through regular company-imposed blackout periods, Quarterhill insiders are prevented from trading in shares or disposing of shares resulting from an option exercise. Trading of Quarterhill securities by insiders is subject to Quarterhill’s insider trading policy. This policy instructs Quarterhill employees and members of its Board of Directors to not buy or sell Quarterhill shares during blackout periods or during other periods in which they are in possession of undisclosed material information.
Generally speaking, blackout periods begin 2 weeks before the end of a fiscal quarter and end the day that financial results for a given fiscal quarter are released.
It is important to know that Company management may be blacked out from trading during times over and above the preset blackout periods because they are in possession of material undisclosed company information. Historically this restriction has resulted in many months of additional blackout periods.
