Liberty Mutual purchased Safeco in 2008 and Ohio Casualty Group in 2007, each of whom started writing surety in 1929. In 2019, it acquired the AmTrust surety activities in the US, Spain and Peru, as well as those of Nationale Borg in the Netherlands and Belgium. These last activities date back to 1893.
