Italy's largest insurer Generali reported first first-half net profit on Thursday that beat market expectations, its strongest half-year performance in five years.

Earnings came in at 1.08 billion euros ($1.4 billion) versus estimates in a Reuters poll of 1.05 billion euros. Operating profit grew to 2.4 billion euros, driven mainly by premium income in its property and casualty (P&C) unit and higher business margins.
