The government, has to step in. AIG is the backbone of the market. I work in the insurance industry and the past two days have been kind of hellish. AIG has/had $1.1 trillion dollars in assets, sure they are not liquid, but they have their hands in everything. If AIG fails, the loan market will fail, no one will be able to get a loan for the simple things like cars. From the insurance standing, there is not an immediate worry. The insurance side of the house operate on their own. AIG is the holding company, for instance, there was talk of non-brokered auto insurance, that is probably AIG direct, separate company. There is over $26 billion in reserves set solely for paying insurance claims, safe for now, bu they did file w/ the state to dip into them if they have to. The different insurance divisions of AIG have a combine ratio between 80-95% (want to be lower than 100% to be profitable). Depending upon state there is also the guarantee fund if a company becomes insolvent and can not pay claims, here in MA it is $300k. Not that it is going to happen, but if it ever did fall out, just switch companies.
