Bill Ford could have sold automaker stock for $18M. He paid $20M to keep it instead.

Bill Ford, executive chair of Ford Motor Company, dramatically expanded his personal investment in the automaker on Wednesday, according to a federal regulatory filing.

He opted to exercise nearly 2 million stock options granted to him as part of his executive pay package. A large portion of the options were set to expire soon and have no value after they expire.

Bill Ford could have sold for $18 million and gone home, but he didn’t. 

Instead, he paid $20.5 million to acquire the nearly 2 million shares.

Rather than exercise the options and sell the shares immediately to realize the gains, Bill Ford opted to exercise the options and buy the shares at the option price. In this case, he paid to acquire the shares and he also paid the associated taxes and fees rather than sell any shares to cover those costs.

If he wanted to cash out, he would have received the difference between the value of the stock options when they awarded and the value when the options were exercised. In this case, it would have been a pretax windfall gain of about $18 million, the company said.

The move reflects Bill Ford’s confidence in the future of the company his great-grandfather founded in 1903, said Mark Truby, Ford chief communications officer. 

By law, Bill Ford is allowed to purchase the stock at the price it was awarded because of how the stock option process is structured. To keep the stock, he must pay the original value at the time he received it. Ford exercised several tranches of stock options priced from $6.19 to $15.37, Ford confirmed.

The Ford Motor Company stock price has recently hovered around a 20-year high in the range of $20 per share. The stock closed at $19.81 on Wednesday, down from $19.96 a day earlier — yet more than twice the price from one year ago.

Executives frequently exercise the options and get a cash payment of the value that stock has appreciated.

Meanwhile, Ford is now headed into an all-electric future, a decision with environmental implications that reflect core values Bill Ford has espoused for decades.

“The decision to acquire almost 2 million shares of common stock reflects Bill’s confidence in the future of the company and our plan to create tremendous value for all of our stakeholders,” Truby told the Free Press on Wednesday.
