WILL AN EMPLOYEE PLAN DETERMINATION LETTER HAVE?
Scope of reliance on determination letter
.01 A determination letter issued pursuant to this revenue procedure contains only the opinion of the Service as to the qualification of the particular plan involving the provisions of §§ 401 and 403(a) and the status of a related trust, if any, under § 501(a). Such a determination letter is based on the facts and demonstrations presented to the Service in connection with the application for the determination letter and may not be relied upon after a change in material fact or the effective date of a change in law, except as provided. The Service may determine, based on the application form, the extent of review of the plan document. Failure to disclose a material fact or misrepresentation of a material fact may adversely affect the reliance that would otherwise be obtained through the issuance by the Service of a favorable determination letter. Similarly, failure to accurately provide any of the information called for on any form required by this revenue procedure may result in no reliance. Applicants are advised to retain copies of all demonstrations and supporting data submitted with their applications. Failure to do so may limit the scope of reliance.
Sections 13 and 14 of Rev. Proc. .02 Except as otherwise provided in this section, determination letters are governed, gener2011–4 applicable ally, by the provisions of sections 13 and 14 of Rev. Proc. 2011–4.

(1) The plan was the subject of a favorable determination letter and the request for that letter contained no misstatement or omission of material facts;
(2) The facts subsequently developed are not materially different from the facts on which the determination letter was based;
