The index excludes certain types of securities, including contingent capital securities, inflation-linked bonds, floating-rate bonds, taxable and tax-exempt municipal securities, structured notes and pass-through certificates. The index is market capitalization weighted. The securities in the index are updated on the last business day of each month.
