Insights

Securities Analyst

TL;DR Insider holdings arising from past RSU grants are being sold in staged transactions; recent three-month sales total 52,085 shares.

The filing documents a proposed sale of 7,915 common shares valued at $225,591 executed through RBC Capital Markets. Acquisition history shows these shares originated from RSU vesting in 2015 and 2016, indicating they are not newly issued. The disclosure of multiple prior sales in the past three months—totaling 52,085 shares and $1,270,190 in proceeds—provides investors clear visibility into recent insider liquidity. On a company-wide basis (12,542,314 shares outstanding), the recent sales represent about 0.4% of outstanding shares, suggesting modest volume relative to the float.

Corporate Governance Expert

TL;DR The filing is a routine Rule 144 notification for vested RSUs; signer confirms no undisclosed material nonpublic information.

The notice follows Rule 144 disclosure conventions, listing the nature of acquisition as RSU vesting and including the mandatory representation that the seller is not aware of material nonpublic information. The sequence of sales over several dates suggests planned disposition rather than a single large liquidation. There is no indication in this filing of any trading plan date under Rule 10b5-1 or other governance actions; the filing simply documents proposed and recent sales.
