12 CFR 614.4362: Loan and lease concentration risk mitigation policy.

The board of directors of each title I, II, and III System institution must adopt and ensure implementation of a written policy to effectively measure, limit and monitor exposures to concentration risks resulting from the institution's lending and leasing activities.

(a) Policy elements. The policy must include:

(1) A purpose and objective;

(2) Clearly defined and consistently used terms;

(3) Quantitative methods to measure and limit identified exposures to significant and reasonably foreseeable loan and lease concentration risks (as set forth in paragraph (b) of this section); and

(4) Internal controls that delineate authorities delegated to management, authorities retained by the board, and a process for addressing exceptions and reporting requirements.

(b) Quantitative methods. (1) At a minimum, the quantitative methods included in the policy must measure and limit identified exposures to significant and reasonably foreseeable concentration risks emanating from:

(i) A single borrower;

(ii) A single-industry sector;

(iii) A single counterparty; or

(iv) Other lending activities unique to the institution because of its territory, the nature and scope of its activities and its risk-bearing capacity.

(2) In determining concentration limits, the policy must consider other risk factors that could identify significant and reasonably foreseeable loan and lease losses. Such risk factors could include borrower risk ratings, the institution's relationship with the borrower, the borrower's knowledge and experience, loan structure and purpose, type or location of collateral (including loss given default ratings), loans to emerging industries or industries outside of an institution's area of expertise, out-of-territory loans, counterparties, or weaknesses in due diligence practices.
