The merger announcement does not spell out changes to policy contracts, billing, claims handling, or service contacts. It therefore does not establish that coverage or service terms changed. For details that apply to an individual policy, check the insurer and legal entity named on the policy documents, coverage terms and renewal date, and the current claims and billing contacts with the insurer or agent.

Why did the companies pursue the merger?
