Context

• This was a director compensation award, not an open-market purchase or sale. Such awards are routine compensation or deferral mechanisms and do not, by themselves, indicate a buy or sell signal by the insider.
• Shares held by a trustee under a deferred compensation plan are payable later and may be subject to deferral elections; they should be treated differently than immediately owned, liquid shares.
