    • 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.
    • 本发明涉及实施和确定定义期限权益价值的投资工具和配套制度及方法。 一方面,本发明包括确定代表正在进行的业务中的潜在股权的投资机会,并选择一个或多个相关股权作为在发行日期发行的定义到期股权投资的基础,并在特定到期日成熟 日期。 每个到期日是指各自定义的到期日股权投资可以兑换为相应赎回价值的未来日期。 可以根据发行日期与定义的到期日权益到期日之间的持续业务经营业绩,计算定义的到期股权投资的赎回价值。
