The value of the change-in-control payout hinges on Aslett's unvested shares and Mercury's stock price. In his resignation letter, Aslett said he was entitled to the change-in-control payout even though that change did not occur. Mercury said its board of directors disputed Aslett's claim to the change-in-control payout. Without it, Aslett would be entitled only to a $2.4 million severance package, a Mercury regulatory filing shows. But the contract stipulates that to be eligible for the change-in-control payout, Aslett also needed to resign for "good reason."
