Catastrophe data aggregator PERILS has updated its estimate of insurance industry losses from the severe convective storms (SCS) that struck Australia’s East Coast in late October, lifting the total almost 37% to AU $1.512 billion (approx US $1.05bn).PERILS came out with its initial insurance industry loss estimate for these severe convective storms back in December, putting the total at AU $1.108 billion.With claims having continued to be filed, the total has risen meaningfully now, increasing 37% to AU $1.512 billion for the second industry loss estimate.The loss estimate is based on data gathered from impacted insurers, including losses from property and motor hull lines of business.
