[5](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: E&O product-page structure description; specific limits and retroactive dates are set on the quote and declarations..)

### Reviewing the Policy Before Purchase

Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim.

- Ask Harper to walk through its exclusions review with you before you bind, since it says two same-limit policies can respond differently to the same claim. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Neither HUB's nor Harper's reviewed pages name an issuing insurer; ask both directly. [4](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
