Our Business

Since 1912, we've grown into the eighth largest global property and casualty insurer based on 2023 gross written premium. We also rank 87 on the Fortune 100 list of largest corporations in the US based on 2023 revenue. ​At Liberty Mutual Insurance we work hard every day to support our customers and our people, so they can protect their families, build their businesses and invest in their futures.

We are headquartered in Boston, but our people, our customers and our reach span the globe. So to better serve our global customers and employees, we are organized into three business units.
