  • Bequest
    Including Bay Ecotarium in your will or estate plan.
  • Life Insurance Policy
    Make Bay Ecotarium a beneficiary of your life insurance policy.
  • Charitable Gift Annuity
    The donor transfers cash or securities in exchange for a charity’s promise to pay a fixed annuity to one or two individuals for life.
  • Charitable Remainder Trust
    You transfer assets to this type of trust in return for income for a period of years or your lifetime. At the death of the surviving beneficiary or the end of a set number of years, the remaining principal in the trust passes to Bay Ecotarium.
  • Charitable Remainder Unitrust
    Beneficiaries receive a fixed percentage (minimum 5%, maximum 50%) of the value of the trust assets as revalued every year (the standard unitrust). Alternatively, the trust may pay the lesser of the unitrust amount or the trust’s actual income (a net-income unitrust); make-up provisions are permitted. Additional contributions are possible.
  • Charitable Reminder Annuity Trust
    A Charitable Remainder Annuity Trust is a vehicle that entails a donor placing a major gift of cash or property into a trust. The trust then pays a fixed amount of income each year to the donor or the donor’s specified beneficiary. When the donor dies, the remainder of the trust is transferred to the charity.
  • Charitable Lead Trust
    The charitable lead trust is the reverse of the charitable remainder trust. The lead trust pays either an annuity or a unitrust amount to one or more charities during the trust term and the remainder passes to the donor or a named beneficiary. Lead trusts can be set up during life (either as grantor or non-grantor trusts) or at death.

Bay Ecotarium in Baltimore is a nonprofit organization under section 501(c)(3) of the Internal Revenue Code. All contributions are tax-deductible to the full extent allowed by law.
