A request for confidential treatment made pursuant to Rule 406 of the Securities Act or Rule 24b-2 of the Exchange Act must:
be sufficiently narrow, so as to only include information eligible for exemption under the FOIA;
specify the basis for the exemption (there are nine FOIA exemptions available, with "trade secrets and commercial or financial information obtained from a person and privileged or confidential" being the most invoked);
contain legal and factual analyses substantiating the exemption;
contain an affirmative representation as to the confidentiality of the information; and
indicate the duration for which the exemption is being sought.
The Commission will not generally grant a request for confidential treatment with respect to information that is specifically required to be disclosed under applicable securities laws or information that is otherwise material to investors.
