So did a little bit of digging on Thornton.....First of all, keep in mind that he can probably get whatever money he wants, whenever. I dont think you can have been a decades long higher up and eventual co-president of the 2nd largest investment bank in the world and not be both well connected, and able to drop a line to a few people and get things funded. He probably is one of the more easily funded people in the world due to his experience, and connections. This is both in the USA, and in China.
Personal wealth? Way more than what a google search says. Apparently he does a good job hiding it, but obviously hes worth waaay more than they say, as in 2012 alone he was paid 18 million in salary.
1. From 2012 to recent times he was paid approximately 95 million to run Barrick Gold. This is straight from their filings.
2. In 2017 they published he had 5,215,000 shares. In 2018 it announced he almost doubled his shares, paying $30 million to now hold around 10,300,000 shares.
3. He sold 2.7 million shares in something like 2019, and seems he sold another 3.5-4 million in 2020, maybe when the price was around its peak. Its anyones guess as to how much he made on the shares but assuming he sold them all prior to 2022 he probably netted a total of $250 million or so from Barrick shares.
4. When he left Goldman Sachs in 2003, the NY Times said he had made $40 million in compensation
5. Also at that time, the NY Times said he had $207 million worth of shares in Goldman Sachs. If he sold it at some time in the past year or two, then he could have made about $950 million from the sale.
6. He made money over the years, including the 2003 to 2012 period sitting on the boards of 7-8 big corporations. For example, he makes $340k a year to sit on fords board.
All of that put together, assuming he used some of his Barrick Gold compensation to buy shares, thus reducing that amount, means if he made no extra money in any other investments, you could reasonably assume a net worth in the range of $1.3 Billion. While he has made over $140-150 million in either compensation or money for sitting on boards in his lifetime, the bulk of that all comes from his shares in Goldman Sachs and in Barrick Gold.
TLDR: Thornton likely has a little over $1 Billion depending on when he sold/will sell some of his stock and if he has any other investments.
