That deal has a break-up fee of 140 million euros that Arcelor would have to pay if it fell apart.

They said no break-up fees would be assessed because both companies had decided to end the merger plan.

The payment was a break-up fee that Apotex would receive if the government rejected the initial settlement deal.

One of the more fascinating tactics in this fight was the use of the break-up fee as both a carrot and a stick.

"We wanted to go higher, but the break-up fee killed us."

There's no guarantee that Vornado would have come back with a new bid even if the break-up fee had been lower.

By pushing so hard for those break-up fees, the firm was able to shut Vornado's effort down.

My understanding is the break-up fee did support this type of scenario.

And Time Warner could have walked away for a break-up fee of about $5 billion until shareholders approved the deal.

The break-up fee on the deal is only $3 billion.
