Barnhart has a bit of time to decide. June 30 is the day that the contract rolls over. So, basically, Mingione is paid a $575,000 per year and is paid that salary over the course of the year in certain increments (not sure if it is weekly, monthly, bi-weekly or what, can't remember and don't care to go look it up). The year starts new on July 1 each year.
His contract states that if he is fired he is owed the remainder of the year plus an additional amount (depending on when he is fired). So, we've almost paid him for the year and if we fire him before June 30 we will only owe him the small amount remaining of the $575,000 (if any) and then 3 years of his salary at 50 percent, or $862,500.
If we wait until July 1, then he's likely to be retained because we'd owe him the fully $575,000, plus his salary for 2 years at 75 percent (again, $862,500).
In short, Barnhart can take about a month to decide what he'll do with this. Probably a good chunk of meetings and such to determine Mingione's fate.
