(a) A credit union shall provide its board of directors a monthly comprehensive report of investment activities, including:
  (1) investments purchased and sold during the month;
  (2) unrealized market gains or losses compared to book value for each security at month's end;
  (3) fair or market value of each security;
  (4) total book value of investments outstanding at month's end;
  (5) unrecorded and unreported obligations to buy or sell investments; and
  (6) amount of investments, other than deposits and investments in designated depositories, that are not either issued by, or fully guaranteed as to principal and interest by, the Federal Deposit Insurance Corporation, the National Credit Union Administration, the United States or any agency, enterprise, corporation, or instrumentality of the United States, or in any trust or trusts established for investing, directly or collectively, in such securities, obligations or instruments.
(b) The credit union shall also provide a quarterly report to the board of directors that summarizes the volatility of the entire security portfolio, if the aggregate amount of securities with one or more of the features included below exceeds the credit union's net worth:
  (1) embedded options;
  (2) remaining maturities greater than three years; or
  (3) coupon formulas that are related to more than one index or are inversely related to, or multiples of, an index.
(c) The report described in subsection (b) of this section must provide a reasonable and supportable estimate of the potential impact, in percentage and dollar terms, of an immediate and sustained parallel shift in market interest rates of plus and minus 300 basis points on the:
  (1) fair value of each security in the entire portfolio;
  (2) fair value of the entire security portfolio as a whole; and
  (3) credit union's net worth.
(d) For the purposes of this section, an embedded option means a characteristic of an investment that gives the issuer or holder the right to alter the level and timing of the cash flows of the investment. Embedded options include call and put provisions and interest rate caps and floors. Since a prepayment option in a mortgage is a type of call provision, a mortgage-backed security composed of mortgages that may be prepaid is an example of an investment with an embedded option.
