MILAN, May 6 (Reuters) - UniCredit on Monday raised its investor reward guidance for the year after posting a much higher net income than expected and further boosting its capital levels.

Italy's second biggest bank said net profit for the January-March period totalled 2.6 billion euros ($2.8 billion), above the 2.13 billion average forecast in a company-compiled analyst consensus.
