Securities Counsel

Form 144 is a broker notice of an affiliate's proposed sale; it does not itself effect a sale.

Form 144 provides notice under federal rules when an affiliate intends to sell restricted or control securities in reliance on an exemption. The filing lists 170,000 shares and records the acquisition method as Private Acquisition from Issuer or an Affiliate on 03/21/2018.

Timing and execution mechanics are not stated in the excerpt; the filing is informational and permits potential market transactions if sale conditions are met. Subsequent transaction reports or exchange records would show completion.

"submitted a Form 144 reporting an intended sale"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

"Private Acquisition from Issuer or an Affiliate | Issuer | 03/21/2018"

Shares outstanding market

"171407939 | 07/01/2026"

Shares outstanding are the total number of a company’s stock units held by all shareholders, including institutional investors and company insiders — think of them as the total number of slices of the company’s ownership pie. Investors use this number to calculate how much of the company each share represents, and it directly affects per-share measures like earnings per share, ownership percentage and valuation; when the slice count changes, an investor’s claim and the company’s per-share metrics change too.
