S&P Dow Jones Indices: Global Industry Classification Standard (GICS
®
) 2
Introduction
Overview
The Global Industry Classification Standard (GICS
) is specifically designed to consistently classify
companies globally, in both developed and developing economies.
In 1999, S&P Dow Jones Indices and MSCI, two leading global index providers, jointly developed GICS to
establish a global standard for categorizing companies into sectors and industries. GICS was developed
in response to the global financial community’s need for one complete, consistent set of global sector and
industry definitions that enable comparisons by company, sector, and industry across countries, regions,
and globally.
The GICS classification system consists of 11 sectors, 25 industry groups, 74 industries, and 163 sub-
industries. The current GICS sectors are:
Energy
Materials
Industrials
Consumer Discretionary
Consumer Staples
Health Care
Financials
Information Technology
Communication Services
Utilities
Real Estate

GICS Methodology
GICS Classification
GICS classifies a company according to its principal business activity. To make this determination, S&P
Dow Jones Indices and MSCI use revenue as the key measure identifying a company’s principal
business activity. However, earnings and market perception are also recognized as important and
relevant for classification purposes and are taken into account during the review process.
A company is classified into the sub-industry whose definition most closely describes the business
activities that generate the majority of the company’s revenues. A company engaged in two or more
substantially different business activities, none of which contributes 60% or more of revenues, is initially
classified into the sub-industry that provides the majority of both the companys revenues and earnings.
To prevent excessive turnover, at least 60% of revenue by a different business activity is the threshold
generally needed to consider a change from a current GICS assignment. When a company has business
activities in three or more sectors, none of which contributes a majority of revenues, the company is
classified either into the Industrial Conglomerates sub-industry (Industrials Sector) or the Multi-Sector
Holdings sub-industry (Financials Sector).
Publicly available information is used when assigning a company’s classification, including Annual
Reports, 10-Ks, company websites, and other official filings.
In the case of a new company, the initial classification is based primarily on the description of the
company’s activities and pro-forma results as given in the prospectus.
If a companys subsidiary files separate financials to its reporting government agency, that subsidiary is
considered a separate entity and classified independently under the GICS methodology. Equity securities
directly linked to a company have the same classification as the company.
GICS classifications are not assigned to mutual funds, closed-end funds, bonds, or Exchange Traded
Funds.
GICS Structure
GICS assigns each company to a sub-industry, and to a corresponding industry, industry group, and
sector, according to the definition of its principal business activity. Since the classification is strictly
hierarchical, at each of the four levels a company can only belong to one grouping.
11 Sectors
25 Industry Groups
74 Industries
163 Sub-Industries
GICS classifications can be presented in either text or numeric formats. The complete GICS classification
for each company is an 8-digit code with text description. The hierarchical design of the 8-digit coding
system allows for easy transition between GICS tiers.

GICS Maintenance
GICS Review
A company’s GICS classification is reviewed annually and is also under constant surveillance for
corporate actions potentially impacting classification.
In general, a companys GICS classification changes whenever there is a major corporate action that
redefines a company's primary business activity. Annual reviews are conducted to ensure that a company
has not redefined its primary business activity through a series of smaller events. To provide a stable
industry classification, changes to a company’s classification are minimized by disregarding temporary
fluctuations in the results of a company’s different business activities.
GICS reviews also occur upon client request.
GICS Structure Review
S&P Dow Jones Indices and MSCI review the GICS structure periodically as needed, which can include
Advisory Panels or open consultations with market participants as needed. The objective is to ensure that
the GICS structure continues to accurately represent global equity markets, enabling seamless global
comparisons by industry.

Changes to the GICS Structure
The four-tier GICS structure accurately reflects equities in today’s global investment environment yet is
flexible enough to capture tomorrow’s developments. The eight-digit GICS coding system is designed to
adapt easily to the changing investment world. As the global economy changes, sectors, industry group,
industries, and sub-industries can be added or divided.

Performance Disclosure/Back-Tested Data
Where applicable, S&P Dow Jones Indices and its index-related affiliates (“S&P DJI”) defines various
dates to assist our clients in providing transparency. The First Value Date is the first day for which there is
a calculated value (either live or back-tested) for a given index. The Base Date is the date at which the
index is set to a fixed value for calculation purposes. The Launch Date designates the date when the
values of an index are first considered live: index values provided for any date or time period prior to the
index’s Launch Date are considered back-tested. S&P DJI defines the Launch Date as the date by which
the values of an index are known to have been released to the public, for example via the companys
public website or its data feed to external parties. For Dow Jones-branded indices introduced prior to May
31, 2013, the Launch Date (which prior to May 31, 2013, was termed Date of introduction”) is set at a
date upon which no further changes were permitted to be made to the index methodology, but that may
have been prior to the Index’s public release date.
Please refer to the methodology for the Index for more details about the index, including the manner in
which it is rebalanced, the timing of such rebalancing, criteria for additions and deletions, as well as all
index calculations.
Information presented prior to an index’s launch date is hypothetical back-tested performance, not actual
performance, and is based on the index methodology in effect on the launch date. However, when
creating back-tested history for periods of market anomalies or other periods that do not reflect the
general current market environment, index methodology rules may be relaxed to capture a large enough
universe of securities to simulate the target market the index is designed to measure or strategy the index
is designed to capture. For example, market capitalization and liquidity thresholds may be reduced. In
addition, forks have not been factored into the back-test data with respect to the S&P Cryptocurrency
Indices. For the S&P Cryptocurrency Top 5 & 10 Equal Weight Indices, the custody element of the
methodology was not considered; the back-test history is based on the index constituents that meet the
custody element as of the Launch Date. Back-tested performance reflects application of an index
methodology and selection of index constituents with the benefit of hindsight and knowledge of factors
that may have positively affected its performance, cannot account for all financial risk that may affect
results and may be considered to reflect survivor/look ahead bias. Actual returns may differ significantly
from, and be lower than, back-tested returns. Past performance is not an indication or guarantee of future
results.
Typically, when S&P DJI creates back-tested index data, S&P DJI uses actual historical constituent-level
data (e.g., historical price, market capitalization, and corporate action data) in its calculations. As ESG
investing is still in early stages of development, certain datapoints used to calculate certain ESG indices
may not be available for the entire desired period of back-tested history. The same data availability issue
could be true for other indices as well. In cases when actual data is not available for all relevant historical
periods, S&P DJI may employ a process of using “Backward Data Assumption(or pulling back) of ESG
data for the calculation of back-tested historical performance. “Backward Data Assumption” is a process
that applies the earliest actual live data point available for an index constituent company to all prior
historical instances in the index performance. For example, Backward Data Assump tion inherently
assumes that companies currently not involved in a specif ic business activity (also known as “product
involvement”) were never involved historically and similarly also assumes that companies currently
involved in a specific business activity were involved historically too. The Backward Data Assumption
allows the hypothetical back-test to be extended over more historical years than would be feasible using
only actual data. For more information on “Backward Data Assumption” please refer to the FAQ. The
methodology and factsheets of any index that employs backward assumption in the back-tested history
will explicitly state so. The methodology will include an Appendix with a table setting forth the specific
S&P Dow Jones Indices: Global Industry Classification Standard (GICS
®
) 10
data points and relevant time period for which backward projected data was used. Index returns shown
do not represent the results of actual trading of investable assets/securities. S&P DJI maintains the index
and calculates the index levels and performance shown or discussed but does not manage any assets.
Index returns do not reflect payment of any sales charges or fees an investor may pay to purchase the
securities underlying the Index or investment funds that are intended to track the performance of the
Index. The imposition of these fees and charges would cause actual and back-tested performance of the
securities/fund to be lower than the Index performance shown. As a simple example, if an index returned
10% on a US $100,000 investment for a 12-month period (or US $10,000) and an actual asset-based fee
of 1.5% was imposed at the end of the period on the investment plus accrued interest (or US $1,650), the
net return would be 8.35% (or US $8,350) for the year. Over a three-year period, an annual 1.5% fee
taken at year end with an assumed 10% return per year would result in a cumulative gross return of
33.10%, a total fee of US $5,375, and a cumulative net return of 27.2% (or US $27,200).
