In addition to the undesignated individual memberships, the club offers seven designated membership categories. Enlistment credit is given in each category. Memorial memberships provide a way to honor the memory of those who have died. The donor is placed on the club mailing list and is invited to attend all C-400 functions. Honor roll memberships pay tribute to the living and are often given by parents to children, children to parents, congregations to pastors, or to anyone a donor wishes to recognize.
Some donors prefer to remain anonymous.
Group Division memberships make it possible for a congregation, women's or men's organization within the church, or other auxiliary groups to join C-400 as a unit in support of Concordia. A group membership may be designated as a memorial or honor roll membership or in commemoration of some historical event in the life of the congregation or group. Funds from these memberships are allocated to the current goals for C-400 unless the donor requests designation for business school scholarships. The donor contributes to the college the amount to cover the annual premium, and the college pays the premium, thus allowing the donor to receive income tax deduction credit. These contributions may be in the form of irrevocable deferred gifts, bequests or insurance policy proceeds.
