Oct 21 (Reuters) - Baker Hughes Co reported a third straight quarterly loss on Wednesday, as a coronavirus-induced slump in commodity prices hurt demand for oilfield equipment and services.

Net loss attributable to the company was $170 million, or 25 cents per share, in the three months ended Sept. 30, compared with a profit of $57 million, or 11 cents per share, a year earlier. (Reporting by Arathy S Nair in Bengaluru; Editing by Shounak Dasgupta)
