Changes to the S&P U.S. Indices are made as needed, with no scheduled reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced two to five days before they are scheduled to be implemented.
Additions to the S&P U.S. Indices are evaluated based on the following eligibility criteria:
●Domicile. Only common stocks of U.S. companies are eligible. For index purposes, a U.S. company has the following characteristics:
othe company files 10-K annual reports;
othe U.S. portion of fixed assets and revenues constitutes a plurality of the total, but need not exceed 50%. When these factors are in conflict, fixed assets determine plurality. Revenue determines plurality when there is incomplete asset information. Geographic information for revenue and fixed asset allocations are determined by the company as reported in its annual filings. If this criteria is not met or is ambiguous, SPDJI may still deem the company to be a U.S. company for index purposes if its primary listing, headquarters and incorporation are all in the United States and/or “a domicile of convenience” (Bermuda, Channel Islands, Gibraltar, islands in the Caribbean, Isle of Man, Luxembourg, Liberia or Panama); and
othe primary listing is on an eligible U.S. exchange.
In situations where the only factor suggesting that a company is not a U.S. company is its tax registration in a “domicile of convenience” or another location chosen for tax-related reasons, SPDJI normally determines that the company is still a U.S. company. The final determination of domicile eligibility is made by the Index Committee, which can consider other factors including, but not limited to, operational headquarters location, ownership information, location of officers, directors and employees, investor perception and other factors deemed to be relevant.
●Exchange Listing. A primary listing on one of the following U.S. exchanges is required: NYSE, NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Select Market, Nasdaq Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX exchanges. Ineligible exchanges include the OTC Bulletin Board and Pink Sheets.
●Organizational Structure and Share Type. Eligible organizational structures and share types are corporations (including equity and mortgage REITS) and common stock (i.e., shares). Ineligible organizational structures and share types include business development companies, limited partnerships, master limited partnerships, limited liability companies, closed-end funds, exchange-traded funds, exchange-traded notes, royalty trusts, special purpose acquisition companies, preferred and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts, rights, American Depositary Receipts and tracking stocks. As of July 31, 2017, companies with multiple share class structures are not eligible to be added to the S&P U.S. Indices, but securities already included in the S&P U.S. Indices have been grandfathered and will remain in the S&P U.S. Indices.
●Market Capitalization. The unadjusted company market capitalization should be within a specified range. Such ranges are reviewed quarterly and updated as needed to ensure they reflect current market conditions. For spin-offs, S&P U.S. Index membership eligibility is determined using when-issued prices, if available.
●Liquidity. Using composite pricing and volume, the ratio of annual dollar value traded (defined as average closing price over the period multiplied by historical volume over the last 365 calendar days) to float-adjusted market capitalization should be at least 1.00, and the stock should trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date.
●IWF. The IWF for each company represents the portion of the total shares outstanding that are considered part of the public float for purposes of the S&P U.S. Indices. An IWF of at least 0.10 is required.
●Financial Viability. The sum of the most recent four consecutive quarters’ Generally Accepted Accounting Principles (GAAP) earnings (net income excluding discontinued operations) should be positive as should the most recent quarter. For REITs, financial viability is based on GAAP earnings and/or Funds From Operations (FFO), if reported.
●Treatment of IPOs. Initial public offerings should be traded on an eligible exchange for at least 12 months before being considered for addition to an S&P U.S. Index. Spin-offs or in-specie distributions from existing constituents do not need to be seasoned for 12 months prior to their inclusion in an S&P U.S. Index.
●Sector Balance. A company is evaluated for its contribution to sector balance maintenance, as measured by a comparison of each GICS® sector’s weight in an index with its weight in the S&P U.S. Total Market Index, in the relevant market capitalization range. The S&P Total Market Index is a float-adjusted, market-capitalization weighted index designed to track the broad U.S. equity market, including large-, mid-, small- and micro-cap stocks.
SPDJI believes turnover in membership in the S&P U.S. Indices should be avoided when possible. At times a stock may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the S&P U.S. Indices, not for continued membership. As a result, a constituent of the S&P U.S. Indices that appears to violate criteria for addition to the S&P U.S. Indices is not deleted unless ongoing conditions warrant an index change.
Calculation of the S&P U.S. Indices
The S&P U.S. Indices are float-adjusted market capitalization-weighted indices. On any given day, the index value of each S&P U.S. Index is the total float-adjusted market capitalization of that S&P U.S. Index’s constituents divided by its divisor. The float-adjusted market capitalization reflects the price of each stock in the relevant S&P U.S. Index multiplied by the number of shares used in the index value calculation.
