Computer systems and computer-implemented methods related to an investment program for an investment vehicle, such as a private placement fund, a limited liability partnership, or a limited liability company, for example, that purchases a life insurance policy and pair it with one or more annuity contracts on the same donor's life. The aggregate sum of the annuity premiums for the annuity contracts may equal, approximately equal, the death benefit payment amount of the purchased life insurance policy. Alternatively, the death benefit payment amount of the purchased life insurance policy may exceed, or greatly exceed, the annuity premiums for the annuity contracts. In addition, the ongoing annuity payments preferably are greater than the life insurance premiums, thereby providing investment vehicle and its investors with a positive rate of return that can be much higher than conventional fixed income investments.
