.01 Master Plan - A “master plan” is a plan (including a plan covering self-employed individuals) that is made available by a sponsor for adoption by employers and for which a single funding medium (for example, a trust or custodial account) is established, as part of the plan, for the joint use of all adopting employers. A master plan consists of a basic plan document, an adoption agreement, and, unless included in the basic plan document, a trust or custodial account document.
.02 Prototype Plan - A “prototype plan” is a plan (including a plan covering self-employed individuals) that is made available by a sponsor for adoption by employers and under which a separate funding medium is established for each adopting employer. A prototype plan consists of a basic plan document, an adoption agreement, and, unless the basic plan document incorporates a trust or custodial account agreement the provisions of which
are applicable to all adopting employers, a trust or custodial account document.
.03 Basic Plan Document - A “basic plan document” is the portion of a plan containing all of the non-elective provisions applicable to all adopting employers. No options (including blanks to be completed) may be provided in the basic plan document, except as provided in section 12.03(1) of this revenue procedure regarding flexible plans.
.04 Adoption Agreement — An “adoption agreement” is the portion of the plan containing the options that may be selected by an adopting employer.
.05 Trust or Custodial Account Document (Note: This definition does not apply if the basic plan document includes a trust or custodial account agreement the provisions of which apply to all adopting employers.) (1) A “trust or custodial account document” is the portion of an M&P plan that contains the trust agreement or custodial account agreement and includes provisions covering such matters as the powers and duties of trustees, investment authority, and the kinds of investments that may be made.
(2) Except as provided in section 5.09 and this section 4.05, all provisions of the trust or custodial account document must be applicable to all adopting employers of that trust, and no options (including blanks to be completed) may be provided in the trust or custodial account document.
(3) With respect to prototype plans, a sponsor or mass submitter may provide up to 10 separate trust or custodial account documents that are intended for use with any single basic plan document. Notwithstanding the preceding sentence, a sponsor or mass submitter may submit more than 10 separate trust or custodial account documents intended for use with any single basic plan document, provided that an additional user fee is submitted for each trust or custodial account document in excess of 10. (4) As provided in section 5.09, a sponsor or M&P mass submitter may provide a trust or custodial account document, designated for use only by adopters of nonstandardized plans, that provides for blanks to be completed with respect to administrative provisions of the trust or custodial account agreement.
