Challenge: The insured, a buyer of a target company, discovered a potential complex tax issue just days before signing that could have a materially negative impact on the investment thesis for acquiring the target (if such issue were successfully challenged by the IRS).


The insured developer of a renewable energy project was seeking an investment from a tax equity investor that would entitle the investor to tax credits. However, the investor wanted a credit-worthy party to provide a 10 year indemnity for certain risks relating to the tax credits.

 AIG underwrote the tax risk and bound a policy that enabled the buyer to proceed with the acquisition while transferring some of the financial risk of an adverse tax determination.

AIG underwrote the complex tax risk and enabled the developer to secure an investment from the tax equity investor and proceed towards completion of the renewable energy project.

 Given our deep expertise and broad appetite, AIG was able to underwrite a complicated tax issue in a compressed deal timeline which allowed the buyer to proceed with the M&A transaction without delay.

AIG’s institutional knowledge, multi-decade experience in underwriting tax insurance and flexibility and agility enabled us to provide a tailored solution in an expedient manner.
