THIS IS AN ANNOUNCEMENT FOR THE MSCI GLOBAL STANDARD INDEXES

MSCI WILL RETAIN THE MSCI GLOBAL INVESTABLE MARKET INDEXES UNCHANGED AND LAUNCH
A NEW INDEX SERIES REFLECTING THE PREFERENCES OF INVESTORS ON UNEQUAL VOTING
STRUCTURES

London - October 30, 2018 - MSCI Inc. (NYSE: MSCI), a leading provider of
research-based indexes and analytics, announced today that the MSCI Global
Investable Market Indexes will continue to reflect the complete investable
equity universe for international institutional investors. Hence, equity
securities with unequal voting structures will continue to be eligible for
inclusion in the MSCI Global Investable Market Indexes at their free float
market capitalization weight. MSCI also announced today that it will launch a
new index series that will reflect the desire of many investors to account for
unequal voting structures in the indexes they use. This decision follows an
extensive, global 18-month long consultation which highlighted the divide in
opinions among international institutional investors.

MSCI supports fully the one share one vote principle as we believe that having
equal voting rights should be an important consideration in equity investing.
The one share one vote principle has also gathered overwhelming support from
participants in the consultation. The treatment of unequal voting structures in
equity benchmarks, however, has proven to be a polarizing question among
international institutional investors. For instance, while many participants
felt strongly that benchmarks should be adjusted to reflect unequal voting
structures, other participants highlighted that the question of unequal voting
rights should be addressed holistically by the stakeholders that are responsible
for operating, regulating and investing in equity markets. These stakeholders
include, among others, securities regulators, stock exchanges, asset owners and
asset managers.

MSCI continues to believe that global market benchmarks, such as the MSCI Global
Investable Market Indexes, should aim to represent the broadest investment
opportunity set available to international institutional investors based solely
on the investability of the underlying markets. Investable market benchmarks
should not be constrained by specific investor opinions, preferences or
constraints including governance issues. This point has been articulated by many
international investors, including asset owners and managers globally, who
clearly highlighted the critical need to find the right balance between investor
views and comprehensive representation of the investable equity universe.

"Current market benchmarks have served the investment community well over the
past decades as an objective reflection of the investable investment opportunity
set available to international institutional investors. As of today, we do not
believe that preferences and constraints on voting rights, among other
governance considerations, should impact the definition of the investable
universe underpinning these benchmarks as equity securities with no or unequal
voting rights are still investable for most investors", said Remy Briand,
Managing Director and Chairman of the MSCI Index Policy Committee.

Briand added, "At the same time, an increasingly large number of international
investors believe that it is important to incorporate additional considerations
beyond investability in their benchmarks and have been using for that purpose a
wide range of standard or customized indexes that incorporate governance
considerations".

Recognizing the increasing importance of voting rights for many equity
investors, MSCI will create an additional index series that will specifically
include voting rights in the eligibility criteria and construction methodology
as described in the last consultation proposal. This new series could be used as
a substitute to the MSCI Global Investable Market Indexes and offer choice and
flexibility to international institutional investors who wish to reflect voting
rights in their equity benchmarks. MSCI plans to launch the new index series in
Q1 2019.

MSCI recognizes that the investment community will need more time to agree on a
single approach to address the divisive question on the treatment of unequal
voting structures. The views of market participants on this topic will continue
to evolve over time and MSCI will actively seek feedback from market
participants on this issue. More information on this topic will be shared as and
when appropriate.
