Before we begin discussing the criteria, we should first outline the overall universe from
which Standard & Poor’s picks Index candidates. Selection begins with Standard & Poor’s
Stock Guide Database of over 10,000 companies. Screened out of the universe are stocks
headquartered in foreign countries, American Depository Receipts (ADRs), American
Depository Shares (ADSs), real estate investment trusts (REITs)1, closed-end funds, equity
derivatives, and tracking stocks2. Initial public offerings (IPOs) within the last six months are
screened out of the S&P MidCap 400- and S&P SmallCap 600-eligible universe, and those
within the last 12 months are screened out of the S&P 500-eligible universe.
A word on foreign stocks is in order. Currently, there are seven foreign companies in the
S&P 500: Royal Dutch Petroleum, Unilever N.V., Nortel Networks, Alcan Aluminum, Inco,
Placer Dome and Barrick Gold. In the early 1990s, the Index Committee announced
that no non-US companies would be added to the S&P 500, specifying that those non-US
companies in the Index would not be removed simply because they are not US companies.
From time to time, this policy has been clarified to explain that criteria for US companies
include incorporation, tax treatment, organization, and location.
Offshore registered companies are sometimes considered domestic, however, with eligibility
examined on a case by case basis. With the announcement of the addition of Global Crossing
to the S&P 500 in September 1999, Standard & Poor’s clarified its position on offshore
registered companies by stating that “… for financial reporting Global Crossing follows GAAP
and is reported in US dollars, the majority of its trading volume is in the US, the majority of its
operations are in the US, and it registered offshore for tax purposes.” Along with Global
Crossing, Carnival, Tyco International, McDermott, Schlumberger, and Transocean Sedco
Forex are all registered offshore.
