Well I did say punish not merely fire. I would expect that to encompass imprisonment and fine, depending on severity. Ending or severely restricting the career and income should be the bonus, lower standard of proof consequence merely for the event happening whilst they're in charge. Separate from a court fine of 5 years salary, all bonuses and share options, or given 3 years in clink. :)

With adequate penalty and frequent enforcement, usual behaviour would change...
