it is a mixture of whole life insurance with some sort of investments (mostly on large corporate bonds and global stock index). The investment has the a floor of 1% return no matter how bad the market will be while it is capped at 13% (i think, I can not remember the exact number). Although it is whole life insurance, the hope is that the return on accumulated cash over 10 years or so can pay the life insurance premium itself as long as the market is not horrible over 10 years. You basically pay 10 years premium for a whole life. Each payment consists of part of life insurance and part of cash you put into for investment. You can 'borrow' the cash balance, interest and tax free, before you die. The loan will be deducted from beneficiary payout when the insurer dies (tax free too).
It is not a bad investment although i do not know how good it will be.
