The Mule Deer Foundation Endowment Fund is structured to exist in perpetuity. The Fund can never be compromised. Your contributions will remain part of the principal portion of the Fund with interest and investment income used to fund projects and initiatives that support the mission of the MDF. The Fund is a way for you to create a lasting legacy to benefit future generations. Pledges may be designated to a specific state such that earnings on those funds may be used to fund projects only in that state.
