Difficult to tie this to executives versus shareholders. Options are taxed.
FINRA 2360 provides disclosure and tax requirements to any organization which issues options, provides grant exercises, or simply issues stock as compensation: https://www.finra.org/rules-guidance/rulebooks/finra-rules/2...
Side note: the regs are partly why you can see detailed information about types and amounts of stock and option activity by different investor classes in tools like https://www.barchart.com/investing-ideas/insider-trading-act...
Nitpick: FINRA rules only apply to FINRA members. For the general versions, you want the SEC rule. (FINRA copies a lot of SEC rules so they can enforce them without the restrictions of a government.)
