§ 2520.104b-1 Disclosure.
(a) General disclosure requirements. The administrator of an employee benefit plan covered by Title I of the Act must disclose certain material, including reports, statements, notices, and other documents, to participants, beneficiaries and other specified individuals. Disclosure under Title I of the Act generally takes three forms. First, the plan administrator must, by direct operation of law, furnish certain material to all participants covered under the plan and beneficiaries receiving benefits under the plan (other than beneficiaries under a welfare plan) at stated times or if certain events occur. Second, the plan administrator must furnish certain material to individual participants and beneficiaries upon their request. Third, the plan administrator must make certain material available to participants and beneficiaries for inspection at reasonable times and places.
(b) Fulfilling the disclosure obligation. (1) Except as provided in paragraph (e) of this section, where certain material, including reports, statements, notices and other documents, is required under Title I of the Act, or regulations issued thereunder, to be furnished either by direct operation of law or on individual request, the plan administrator shall use measures reasonably calculated to ensure actual receipt of the material by plan participants, beneficiaries and other specified individuals. Material which is required to be furnished to all participants covered under the plan and beneficiaries receiving benefits under the plan (other than beneficiaries under a welfare plan) must be sent by a method or methods of delivery likely to result in full distribution. For example, in-hand delivery to an employee at his or her worksite is acceptable. However, in no case is it acceptable merely to place copies of the material in a location frequented by participants. It is also acceptable to furnish such material as a special insert in a periodical distributed to employees such as a union newspaper or a company publication if the distribution list for the periodical is comprehensive and up-to-date and a prominent notice on the front page of the periodical advises readers that the issue contains an insert with important information about rights under the plan and the Act which should be read and retained for future reference. If some participants and beneficiaries are not on the mailing list, a periodical must be used in conjunction with other methods of distribution such that the methods taken together are reasonably calculated to ensure actual receipt. Material distributed through the mail may be sent by first, second, or third-class mail. However, distribution by second or third-class mail is acceptable only if return and forwarding postage is guaranteed and address correction is requested. Any material sent by second or third-class mail which is returned with an address correction shall be sent again by first-class mail or personally delivered to the participant at his or her worksite.
