Context

• This was a net-share (cashless) exercise of vested options rather than an open-market sale — the company withheld shares to satisfy exercise price and taxes. Such exercises are routine for executives exercising vested options and do not, by themselves, indicate a buy or sell sentiment.
• The filing shows the usual legal disclaimers about beneficial ownership and identifies some holdings held in irrevocable trusts for minor children.
