In 1997, Allstate decided to form separate companies in which they would write all of their Florida business.The companies were wholly owned subsidiaries of Allstate Holdings, LLC, which, in turn, was a wholly owned subsidiary of Allstate Insurance Company, the flagship company in the Allstate group.The new companies were named Allstate Floridian Insurance Company and Allstate Floridian Indemnity Company.In 2009, Allstate decided to change the names of these Florida-only subsidiaries.Allstate Floridian Insurance Company became Castle Key Insurance Company.Allstate Floridian Indemnity Company became Castle Key Indemnity Company.The names changed, but the ownership structures did not: they are still wholly owned subsidiaries within the Allstate group.

Explain why you think 1) Allstate separated its Florida business into separate companies and 2) why Allstate changed the name.
