After weeks of internal debate, the Treasury Department has allowed insurers who purchased banks to participate in the Capital Purchase Program (CPP). Under the CPP, Treasury purchases non-voting preferred stock in a bank and receives a dividend of five percent rising to nine percent. Some large insurers immediately announced they did not need assistance. Some other interested insurers had not completed their bank purchase and under Treasury's view would not be eligible. Insurers who have not bought a bank cannot stop at the CPP window. The CPP is one of several parts of the Troubled Asset Relief Program (TARP) which has invested $600 billion in financial institutions since October 2008.
