Goldman Sachs and Credit Suisse First Boston stand to share $112m (€127.3m) in fees from advising AT&T, the US telecom group, on its sale of AT&T Broadband.

The size of the fees mean that the $72bn acquisition of AT&T Broadband by Comcast, the US cable group, is to go down as the biggest fee-earner in US mergers and acquisitions history - so long as the deal gets approved by US regulators.
