HOMEGROWN chipmaker Chartered Semiconductor Manufacturing was unable to arrest its downward spiral and continues to be in the red this third quarter.

It made a net loss of US$4.7 million (S$6.57 million), compared to the US$24.4 million it lost in the same quarter last year.

To date this year, it has lost almost US$143 million, including a US$8.4 million transaction cost related to its proposed buyout by an Abu Dhabi company.

Its revenue of US$415.2 million for the quarter was also down 10.4 per cent compared to the same period last year.

The loss per share was one US cent for the quarter, or a cumulative 22 US cents for the nine months ended Sept 30.

Its factories were 75 per cent used, compared to 85 per cent a year ago.
