Both AIG and Progressive are members of IA (Intercompany Arb)...

Did they put the denial in writing? I would call AIG and find out why they are denying the claim. Even if they say your wife was speeding, she would be comparatively negligent only, with the majority of the liabillity resting with the backing party. He backed into the side of you guys, making him at fault.

I will PM my phone and you can call if you have any questions. - Mike (& Kristy)
