Historical example of a termination fee
In February 2016, LinkedIn began entertaining purchase offers from multiple companies. Microsoft (MSFT +1.50%) and Salesforce (CRM -0.84%) were the final two bidders involved in negotiations. In May 2016, LinkedIn chose Microsoft's offer of $182 per share, all cash, and the two companies signed a letter of intent. While Microsoft wanted a termination fee of $1 billion, LinkedIn negotiated it down to $725 million.
Over the next month, Salesforce revised its offer multiple times. Even though LinkedIn would've had to pay Microsoft a termination fee, it informed Microsoft that the original offer was no longer supportable. Microsoft eventually agreed to increase its offer to $196 per share, all cash. LinkedIn's board of directors met later that day, considering the new offer, the offers from Salesforce, and the cost of the termination fee. After discussing it, they voted to approve the transaction, and Microsoft officially purchased LinkedIn.
