Could the Plan have expired? Is it some anniversary of when such sales first commenced?
Likely different execs would have different criteria for when sales should be executed, so it seems unlikely that everyone would have suddenly switched to a no-sale regime.
MNTA—28 days have now elapsed without a 10b5-1 insider sale by anybody. This has not happened since the 10b5-1 plans were established (except during blackout periods just prior to quarterly earnings).
