(i) Subsequent to obtaining approval of the form of a master or prototype plan, a sponsoring organization may wish to amend the plan. Whether a sponsoring organization may effect an amendment depends on the plan's administrative provisions.
(ii) If the plan provides that each subscribing employer has delegated authority to the sponsor to amend the plan and that each such employer shall be deemed to have consented thereto, the plan may be amended by the sponsor acting on behalf of the subscribers. If the plan does not contain such provision but all subscribing employers consent in a collateral document to permit amendment, the sponsor, acting on their behalf, may amend the plan. However, where a sponsor is unable to secure the consent of each such employer, the plan cannot be amended. In such cases any change can only be effected by the establishment of a new plan and the submission of a new Form 4461 by the sponsor. The new plan must be complete and separate from the old plan, and individual employers may, if they desire, substitute the new plan for the old plan.
(iii) Where the plan has been amended pursuant to subdivision (ii) of this subparagraph, the sponsor is to submit an application, Form 4461, a copy of the amendment, a description of the changes, and a statement indicating the provisions in the original plan authorizing amendments, or a statement that each participating employer's consent has been obtained.
(iv) Upon approval of the amendment by the National Office, an opinion letter will be issued to the sponsor containing the serial number of the original plan, followed by a suffix: “A-1” for the first amendment, “A-2” for the second amendment, etc. Employers adopting the form of plan subsequent to the date of the amendment must use the revised serial number.
(v) If a new plan is submitted, together with Form 4461 and copies of all documents evidencing the plan, an opinion letter bearing a new serial number will be issued to the sponsor, and all employers who adopt the new plan are to use the new serial number. Employers who adopted the old plan continue to use the original serial number. However, any employer who wishes to change to the new plan may do so by filing with his district director a new Form 4462, indicating the change.
(vi) An employer who amends his adoption agreement may request a determination letter as to the effect of such amendment by filing Form 4462 with his district director, together with a copy of the amendment and a summary of the changes. However, in the event an employer desires to amend his adoption agreement under a master or prototype plan, and such amendment is not contemplated or permitted under the plan, then such amendment will in effect substitute an individually designed plan for the master or prototype plan and the amendment procedure described in paragraph (o) of this section will be applicable.
