The Underlying Index includes publicly-issued U.S. Treasury securities that have a remaining maturity greater than one year and less than or equal to thirty years and have $300 million or more of outstanding face value, excluding amounts held by the Federal Reserve System (the Fed ) Open Market Account or bought at issuance by the Fed. As of October 31, 2020, the dollar-weighted average maturity of the Underlying Index was 8.32 years. In addition, the securities in the Underlying Index must be fixed-rate and denominated in U.S. dollars. Excluded from the Underlying Index are inflation-linked securities, cash management bills, Treasury bills, any government agency debt issued with or without a government guarantee and zero coupon issues that have been stripped from coupon-paying bonds. The Underlying Index is weighted by market capitalization excluding amounts held by the Fed Open Market Account or bought at issuance by the Fed, and the securities in the Underlying Index are updated on the last business day of each month. |
