12 CFR 703.9: Safekeeping of investments.

(a) A Federal credit union's purchased investments and repurchase collateral must be in the Federal credit union's possession, recorded as owned by the Federal credit union through the Federal Reserve Book-Entry System, or held by a board-approved safekeeper under a written custodial agreement that requires the safekeeper to exercise, at least, ordinary care.

(b) Any safekeeper used by a Federal credit union must be regulated and supervised by either the Securities and Exchange Commission, a Federal or State depository institution regulatory agency, or a State trust company regulatory agency.

(c) A Federal credit union must obtain and reconcile monthly a statement of purchased investments and repurchase collateral held in safekeeping.

(d) Annually, the Federal credit union must analyze the ability of the safekeeper to fulfill its custodial responsibilities, as evidenced by capital strength, liquidity, and operating results. The Federal credit union should consider current financial data, annual reports, external assessments of creditworthiness, relevant disclosure documents, and other sources of financial information.
