The Committee on Maintenance of Union Membership, known as the MUM Committee, is charged with the responsibility of administering the Proportional Dues Program. This dues program is the method by which the congregational members of the Union for Reform Judaism have agreed to assess themselves in order to provide financial support to the Union and Hebrew Union College-Jewish Institute of Religion (HUC-JIR).

The funds raised through the system help:

• To train rabbis, cantors, educators and community workers
  
• To provide visionary leadership and direct services to congregations in order to ensure that Reform Judaism flourishes in every community, large or small, in which Reform Jews live
  
• To develop and produce new religious education curricula, books, programs, and tools for synagogue management
  
• To provide camps for children
  
• To support a network of congregational support centers
  
• To support representation in the national and international Jewish community and to the Religious Action Center of Reform Judaism (RAC) in Washington D.C.

The Proportional Dues Program and the delegation of the administration of the program are found in the Bylaws of the Union for Reform Judaism. As a point of general interest, there are only two committees established in the constitution of the Union -- the Executive Committee and the Committee on Maintenance of Union Membership.
