NEW YORK, Aug 30 (Reuters) - Goldman Sachs ( GS )

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.
