Goldman Sachs' chief administrative officer Edward Forst said the Global Services Centre based in the technology hub of Bangalore which began operations last year had expanded its portfolio to include treasury, equity and asset management.

Frost told reporters that the Indian centre offered a cost advantage of about 50 percent compared to other such centres in the United States and Europe.

Bangalore, the high-tech capital of India, is home to more than 1,500 domestic and foreign technology firms.
