Personal lines insurer The Allstate Corporation has reported $300m in estimated pre-tax catastrophe losses from 13 events during the month of June 2011.

The personal lines insurer says that losses in June added to previously announced losses in April and May, for a total of estimated $2.3bn in Q2.

Allstate’s announcement of losses is a continuation of a new plan to release monthly and quarterly catastrophe losses when they exceed $150m.

The Allstate Corporation offers a broad range of personal property and casualty insurance products, such as life insurance, annuities, funding agreements, and commercial property and casualty coverages.
