How we map holdings to the
sectors above: each holding's issuer carries a U.S. SIC industry code in its
EDGAR filer record, and each SIC code rolls up to a sector. Expand a sector to
see its industries, and click a SIC code to list this fund's positions in that
industry. Bonds and foreign or private issuers with no SEC filer record fall
into Unclassified.
