Workers compensation insurance companies in Delaware submit a rate application as a group once a year, and then each company uses that group application as a base for its rates. The Insurance Commissioner must review and approve the rates.

In 2005 and 2006, Commissioner Denn held a public hearing on the combined workers comp insurance rate application, allowing the public as well as businesses and labor groups to comment on the proposed rates. Prior to Commissioner Denn, a public hearing had never been held on these rate applications. The Commissioner also hired an independent actuary with experience in workers comp to review the proposed rate increases.
