The policy shall establish standards for the making of prudent investments which shall include (1) the rating of individual investments by nationally recognized rating services, if any, and (2) standards for diversification of the credit union’s investment portfolio among industry categories. The policy shall provide for the frequent and periodic review by the credit union of investments made pursuant to the policy and shall provide for the reasonable and expeditious divestiture of investments which the governing board, upon its review, no longer deems prudent or consistent with the credit union’s investment policy. The investment policy and any investment made pursuant to the policy shall be subject to the supervision of the commissioner concerning safe and sound credit union practices.

(b) The investment officer or investment committee, if any, shall act for the governing board between meetings of the governing board in all matters involving investment of funds pursuant to this section.

The minutes of the governing board meetings shall recite the results of each such review. The governing board shall cause the credit union to use reasonable efforts to divest as expeditiously as possible any investment which the governing board, upon its review, no longer deems prudent or consistent with the Connecticut credit union’s investment policy.

(c) A Connecticut credit union may invest its funds, which are not committed to loans to members in: (1) Securities, obligations, or other instruments of, or issued by, or fully guaranteed as to principal and interest by the United States or any of its agencies or instrumentalities, or in any trusts established for investing directly or collectively in such instruments; (2) general obligations and revenue obligations of any state or territory of the United States, or any political subdivision thereof, provided such obligations are rated in the three highest rating categories by a rating service of such obligations recognized by the commissioner and no more than ten per cent of total assets may be invested in any one issuer; (3) obligations or other instruments or securities of the Student Loan Marketing Association; (4) federal funds, shares, share certificates or other share deposits of any other Connecticut credit union, federal credit union or out-of-state credit union whose share accounts or deposits are insured by the National Credit Union Administration, or its successor agency; (5) loans not exceeding twenty per cent of the lending credit union’s total assets to any other Connecticut credit union, federal credit union or out-of-state credit union; (6) federal funds of or deposit accounts with a Connecticut bank, federal bank or out-of-state bank the accounts of which are insured by the Federal Deposit Insurance Corporation or its successor agency; (7) shares of, deposits with or loans to any federal reserve bank or any central liquidity facility established under state or federal law; (8) shares of, deposits with or loans to any corporate Connecticut credit union, corporate federal credit union or corporate out-of-state credit union; (9) shares of stock or obligations of or loans to a national or state credit union association or credit union corporation of which the credit union is a member, provided such investment does not constitute a controlling interest in such association or corporation or does not in the aggregate exceed one per cent of the total assets of the credit union; (10) real estate and improvements thereon, furniture, fixtures and equipment for the present or future use of the Connecticut credit union, provided such investment may not in the aggregate exceed twenty per cent of the total assets of the Connecticut credit union without the written approval of the commissioner; (11) debt mutual funds and equity mutual funds, provided the portfolios of such mutual funds consist solely of investments described in subdivisions (1) to (3), inclusive, of this subsection; (12) fixed or variable rate asset-backed securities, collateralized mortgage obligations and real estate mortgage investment conduits, except stripped mortgage-backed securities, residual interests, mortgage servicing rights, commercial mortgage related securities or small business-related securities; (13) money market funds rated in the three highest rating categories by a rating service of such funds recognized by the commissioner; (14) repurchase agreements and reverse repurchase agreements provided (A) the underlying securities are legal investments for Connecticut credit unions, (B) the Connecticut credit union receives a daily assessment of the market value of the underlying securities, including accrued interest, and maintains an adequate margin that reflects a risk assessment of the underlying securities and the term of the agreement, and (C) the Connecticut credit union has entered into signed contracts with all approved counterparties; and (15) Yankee dollar deposits, Eurodollar deposits, banker’s acceptances, deposit notes and bank notes with original weighted average maturities of less than five years and issued by a Connecticut bank, federal bank or out-of-state bank.

(d) A Connecticut credit union may, subject to the provisions of subsections (e), (f) and (g) of § 36a-461a, invest its funds in or make loans to credit union service organizations provided (1) the total of any such investment in or loan to any one credit union service organization does not exceed two per cent of the total assets of the credit union without regard to the amount derived from the profitability of such credit union service organization, and (2) the credit union shall file with the commissioner prior written notice of its intention to make such investment or loan. The Connecticut credit union may make such investment or loan unless the commissioner disapproves such investment or loan not later than thirty business days after the notice is filed. The thirty-day period may be extended by the commissioner, in writing, if the commissioner determines that the notice raises issues that require additional information or additional time for analysis.

(e) In addition to other investments authorized by this section, a Connecticut credit union may, with the prior written approval of the commissioner, invest its funds in: (1) Debt securities, equity securities, debt mutual funds and equity mutual funds without regard to any other liability to the Connecticut credit union of the maker, obligor, guarantor or issuer of such securities and mutual funds provided: (A) The securities and mutual funds are rated in the three highest rating categories by a rating service of such securities and mutual funds recognized by the commissioner or, if not so rated, are determined by the credit union’s governing board to be a prudent investment, (B) the total amount of such securities and mutual funds of any one maker, obligor or issuer invested in by a Connecticut credit union may not exceed at any time twenty-five per cent of its capital, (C) the total amount of such debt securities and debt mutual funds may not exceed at any time twenty-five per cent of its total assets, (D) the total amount of such equity securities and equity mutual funds may not exceed at any time twenty-five per cent of its total assets, and (E) a Connecticut credit union may not engage in securities trading, including when-issued trading and pair-off transactions without additional prior written approval of the commissioner; and (2) subject to any limitations imposed by the commissioner, in any other investment the commissioner deems appropriate in light of such factors as the financial condition and strategic goals of the Connecticut credit union and the degree of risk inherent in the investment, provided the credit union demonstrates that sufficient resources, knowledge, systems and procedures are in place to monitor and control the risks involved.

(f) All securities in which a Connecticut credit union invests shall be registered in the name of the credit union. Records of securities owned by such credit union shall be maintained at the main office of such credit union. The records held by such credit union concerning its account with any of the depositories or financial institutions holding its securities, and the securities registered in its name and held by it, shall be subject to inspection at any time during business hours by any director, member of senior management or member of the supervisory committee of the Connecticut credit union.
