What Are the Key Differences Between AIG and CNA General Liability Insurance?

Coverage Description and Buyer Segment

CNA says its commercial general liability addresses amounts a business may owe third parties for covered bodily injury or property damage, and identifies solutions for small, mid-sized and large firms. AIG's directory places GL in selected industry programs but does not specify occurrence definitions or covered operations. Buyers should compare CNA's stated third-party focus with the AIG program's actual insuring agreement, especially for products and completed operations. [1] [3]

Claims and Risk Support

CNA describes industry-specific underwriting and risk-control support and claims professionals for the GL line. AIG describes underwriting, claims and loss-control teams for its program administrators. Ask CNA which segment and services fit the company, then identify the AIG administrator and confirm whether risk-control support is included in the quoted program. [1] [3]
