NEW YORK (Reuters) -Goldman Sachs President and Chief Operating Officer John Waldron has sold 18,244 in company stock, according to a filing Friday.

The sales are worth an estimated $13.6 million based on Friday's closing price of $745.25 a share.

Waldron, widely seen as the likely successor to CEO David Solomon, still holds about 300,000 in Goldman stock, according to estimates based on company filings.

Both executives were awarded share retention bonuses of $80 million this year.

Waldron joined Goldman's board in February. He has held his current roles since October 2018, overseeing the leaders of the bank's three main divisions. Previously, he was co-head of investment banking, a role he assumed in 2014 after joining Goldman in 2000.
