Ask Alliance Risk which contract clauses affect your placement and ask WTW what review it offers for your sector. [1] [8]

Claims support and policy process

Alliance Risk says E&O clients can access a legal network and claims experts familiar with their industry. WTW describes reviewing binders, policies and endorsements against negotiated terms; these records describe different points in the process. Ask Alliance Risk what assistance begins after a claim is reported, and ask WTW who will review the final wording and help coordinate with the carrier. [1] [7]

What Should You Confirm in Alliance Risk and WTW Professional Liability (E&O) Insurance Quotes?

  • Ask Alliance Risk how prior acts, retroactive dates and tail coverage are reflected in the quote for your services. [1]
