(a) Assessment risk assignment. For the purpose of determining the annual assessment rate for insured depository institutions under § 327.16, each insured depository institution will be provided an assessment risk assignment. Notice of an institution's current assessment risk assignment will be provided to the institution with each quarterly certified statement invoice. Adjusted assessment risk assignments for prior periods may also be provided by the Corporation. Notice of the procedures applicable to reviews will be included with the notice of assessment risk assignment provided pursuant to this paragraph (a).

(b) Payment of assessment at rate assigned. Institutions shall make timely payment of assessments based on the assessment risk assignment in the notice provided to the institution pursuant to paragraph (a) of this section. Timely payment is required notwithstanding any request for review filed pursuant to paragraph (c) of this section. Assessment risk assignments remain in effect for future assessment periods until changed. If the risk assignment in the notice is subsequently changed, any excess assessment paid by the institution will be credited by the Corporation, with interest, and any additional assessment owed shall be paid by the institution, with interest, in the next assessment payment after such subsequent assignment or change. Interest payable under this paragraph shall be determined in accordance with § 327.7.

(c) Requests for review. An institution that believes any assessment risk assignment provided by the Corporation pursuant to paragraph (a) of this section is incorrect and seeks to change it must submit a written request for review of that risk assignment. An institution cannot request review through this process of the CAMELS ratings assigned by its primary federal regulator or challenge the appropriateness of any such rating; each federal regulator has established procedures for that purpose. An institution may also request review of a determination by the FDIC to assess the institution as a large, highly complex, or a small institution (§ 327.16(f)(3)) or a determination by the FDIC that the institution is a new institution (§ 327.16(g)(5)). Any request for review must be submitted within 90 days from the date the assessment risk assignment being challenged pursuant to paragraph (a) of this section appears on the institution's quarterly certified statement invoice. The request shall be submitted to the Corporation's Director of the Division of Insurance and Research in Washington, DC, and shall include documentation sufficient to support the change sought by the institution. If additional information is requested by the Corporation, such information shall be provided by the institution within 21 days of the date of the request for additional information. Any institution submitting a timely request for review will receive written notice from the Corporation regarding the outcome of its request. Upon completion of a review, the Director of the Division of Insurance and Research (or designee) or the Director of the Division of Supervision and Consumer Protection (or designee) or any successor divisions, as appropriate, shall promptly notify the institution in writing of his or her determination of whether a change is warranted. If the institution requesting review disagrees with that determination, it may appeal to the FDIC's Assessment Appeals Committee. Notice of the procedures applicable to appeals will be included with the written determination.

(d) Disclosure restrictions. The portion of an assessment risk assignment provided to an institution by the Corporation pursuant to paragraph (a) of this section that reflects any supervisory evaluation or confidential information is deemed to be exempt information within the scope of § 309.5(g)(8) of this chapter and, accordingly, is governed by the disclosure restrictions set out at § 309.6 of this chapter.

(e) Limited use of assessment risk assignment. Any assessment risk assignment provided to a depository institution under this part 327 is for purposes of implementing and operating the FDIC's risk-based assessment system. Unless permitted by the Corporation or otherwise required by law, no institution may state in any advertisement or promotional material, or in any other public place or manner, the assessment risk assignment provided to it pursuant to this part.

(f) Effective date for changes to risk assignment. Changes to an insured institution's risk assignment resulting from a supervisory ratings change become effective as of the date of written notification to the institution by its primary federal regulator or state authority of its supervisory rating (even when the CAMELS component ratings have not been disclosed to the institution), if the FDIC, after taking into account other information that could affect the rating, agrees with the rating. If the FDIC does not agree, the FDIC will notify the institution of the FDIC's supervisory rating; resulting changes to an insured institution's risk assignment become effective as of the date of written notification to the institution by the FDIC.

(g) Designated Reserve Ratio. The designated reserve ratio for the Deposit Insurance Fund is 2 percent.
