The invention relates to investment vehicles and supporting systems and methods for implementing and determining the value of a defined maturity equity. In one aspect, the invention includes identifying investment opportunities that represent underlying equity interests in ongoing businesses and selecting one or more of the underlying equities as a basis for a defined maturity equity investment to be issued on an issuance date and to mature on a particular maturity date. Each maturity date represents a future date on which the respective defined maturity equity investment may be redeemed for a respective redemption value. A redemption value may be calculated for the defined maturity equity investment based on operational results of the ongoing business between the issuance date and the maturity date of the defined maturity equity.
