Why it may matter

• These were open market sales reported under a 10b5-1 plan; the filing notes some of the securities sold were RSUs rather than shares held free of restrictions.
• The filing records beneficial ownership through multiple trusts for which Reinstra serves as trustee; it does not provide a single post-transaction total shares owned in the provided details.
• A filing does not show why the insider traded or why the company acted.
