He also has a small stake — from $1-$15,000 worth of stock — in the Russian internet company Yandex, a stock commonly held by Westerners that is traded on NASDAQ.
Tillerson's stock holdings in Chinese and Russian companies are all $50,000 and under.
His largest holdings overall are in Exxon stock and financial instruments including mutual funds and indexed funds. In total, Tillerson has at least $200 million in Exxon-related holdings.
In addition, Tillerson has large holdings in Texas municipal bonds. He and his wife, Renda St. Clair, jointly own a large horse ranch in Texas that is valued at as much as $25 million. They also have real estate holdings elsewhere in the state.
Using the maximum value for the holdings published, Tillerson's total assets would be close to half a billion dollars.
His holdings rival those of former Treasury Secretary Henry Paulson, who liquidated his own holdings of more than $500 million before taking on that role in 2006.
Tillerson will likely have to divest some of his direct holdings in stock like Exxon. However, due to a tax provision created in the Bush administration for people nominated for an executive branch position, Tillerson can take those holdings and invest them for three years in a "permitted property."
That means his tax hit would be negligible to non-existent.
In addition, Exxon Mobil's board has reached an agreement with Tillerson for vesting his pension in a fashion that his lawyers say won't violate ethics rules. An issue over deferred compensation had required him staying with the firm through March.
