Abstract: An investment system includes a computer-implemented annuity system generating annuity proposals for customers. The annuity system includes a memory storing customer information input from a customer and annuity information, and a processor, connected to the memory. The processor retrieves the customer and annuity information from the memory, and generates an annuity proposal responsive to the customer and annuity information. According to the annuity system, the annuity proposal includes one of fixed period installments, life, joint and survivor, joint and contingent and proceeds at interest annuities. The proceeds at interest annuity may also be viewed as a flexible Certificate of Deposit (CD) investment proposal for use by companies providing banking services.
