What is a Rule 10b5-1 trading plan?

A Rule 10b5-1 trading plan is a written document adopted by an insider (like a company executive) that predetermines the purchase or sale of company stock. It allows insiders to trade securities at a time when they do not possess material non-public information, thus avoiding insider trading concerns. The plan specifies the number of shares, prices, and dates for trades.

How many shares could Ms. Lalor sell, and what are the conditions?

Ms. Lalor could sell up to a maximum of 4,976 shares of 3M common stock. These sales are subject to specific minimum price thresholds outlined in the plan and will occur over a period ending August 11, 2011.

Will Ms. Lalor still own a significant amount of 3M stock after these potential sales?

Yes, according to the filing, even if all planned transactions execute, Ms. Lalor will remain above the minimum stock ownership thresholds established by 3M Company. This indicates she is maintaining a substantial commitment to the company's stock.
