Citigroup, the US banking group which employs more than 1,100 people in Dublin, reported core third-quarter income of $3.26 billion (E;3.6 billion) for the third quarter to end-September or 63 US cents per share. The results included $502 million, or 10 cents per share, in after-tax losses related to insurance claims, as well as costs of about $200 million or four cents per share due to the disruption of business as a result of the September 11th terrorist attacks in New York.
