Insights

Securities Analyst

TL;DR Insider plans a small proposed sale (1,326 shares) after recent significant dispositions totaling 50,000 shares ($1.35M).

The filing documents a routine Rule 144 notice for the proposed sale of 1,326 common shares with an indicated market value of $37,791. The shares being offered were originally acquired via RSU vesting in 2015 and 2016, which typically indicates long-held, vested compensation shares rather than recent purchases. Notably, the same account (Stephen Taylor via RBC) completed 50,000 shares of sales in the prior three months for gross proceeds of $1,350,268, demonstrating ongoing liquidation activity. For investors, this is informational: the proposed sale is small relative to the recent 50,000-share disposals, and the filing contains no new financial or operational disclosures about the issuer.

Compliance & Risk Specialist

TL;DR Filing appears procedurally complete for a Rule 144 sale; signer affirms no undisclosed material adverse information.

The Form 144 supplies required acquisition dates, nature of acquisition (RSU vest), broker name, proposed sale date, and outstanding share count. The signatory affirms the absence of undisclosed material adverse information and includes a history of recent sales aggregated for the account. From a compliance perspective, the form meets disclosure elements necessary for a Rule 144 notice. There are no indications in the filing of noncompliance, contested transfers, or alternative payment arrangements. The filing is therefore a routine disclosure of intended insider selling activity rather than a disclosure of issuer-specific risk events.
