3 terms

privately negotiated transactions financial

"may repurchase shares ... via the open market and/or privately negotiated transactions"

Privately negotiated transactions are deals made directly between parties without involving a public marketplace or open auction. They are like private sales between two individuals rather than items sold at a busy marketplace open to everyone. For investors, these transactions can offer more tailored terms and privacy, but they may also carry different risks and less transparency compared to public exchanges.

Rule 10b5-1 trading plans regulatory

"Repurchases ... may be effected pursuant to Rule 10b5-1 trading plans"

Rule 10b5-1 trading plans are written, pre-arranged instructions that allow company insiders (such as executives or directors) to automatically buy or sell their company's stock at specified times or under set conditions, like a standing instruction or automated thermostat for trades. They matter to investors because these plans provide a legal defense against insider‑trading accusations and create predictable insider trading patterns that can help signal whether sales are routine portfolio management or potentially meaningful to the company’s outlook.
