Employers Holdings, Inc.
A specialty insurer that sells workers' compensation coverage to small businesses in lower-risk fields like restaurants, retail, and professional services. It began in 1913 as Nevada's state-run insurance fund, then was privatized in 2000 and went public in 2007, becoming the first mutual holding company in Nevada along the way. Fun fact: the company grew out of a government monopoly — for decades it was the only game in town for Nevada employers — before transforming into the publicly traded insurer it is today.
No tracked superinvestors held this security in this period.
