MSCI transitioned the existing MSCI China A Index to the MSCI Global Investable Market Indexes (GIMI) methodology in two phases which coincided with the August 2009 Quarterly Index Review and the November 2009 Semi-Annual Index Review, respectively.
First phase of the transition coincided with the August 2009 Quarterly Index Review: - The enhanced MSCI China A Index was rebalanced as per the GIMI Methodology
and compared to the existing MSCI China A Index.
- All companies in the enhanced MSCI China A Index but not in the existing MSCI China A Index were added to the existing MSCI China A Index at half of their free float-adjusted market capitalization, and all companies that were not in the enhanced MSCI China A Index but in the existing MSCI China A Index were retained in the existing MSCI China A Index but at only half of their free float-adjusted market capitalization.
Second phase of the transition coincided with the November 2009 Semi-Annual Index Review:
- The enhanced MSCI China A Index was rebalanced.
- All differences between the rebalanced enhanced MSCI China A Index and the existing MSCI China A Index were fully implemented in the existing MSCI China A Index and converged with the enhanced MSCI China A Index.
Methodology Adaptations Specific to the MSCI China A Index
The MSCI China A Index shares a methodology similar to that of the MSCI Global Investable Market Indexes, with the following methodology adaptations:
Equity Universe:
For the MSCI China A Index, the universe is defined as all China A shares listed on the Shanghai and Shenzhen Stock Exchanges. In general, all listed equity securities, or listed securities that exhibit characteristics of equity securities, except investment trusts, mutual funds and equity derivatives, are eligible for inclusion in the universe. Securities with a “ST” or “*ST” status are excluded from the Equity Universe (see Appendix I for more details).
Equity Universe Minimum Size:
The Equity Universe Minimum Size applied to the MSCI China A Index is based on the Global Minimum Size Reference of the Emerging Markets under the MSCI Global Investable Market Indexes Methodology.
Assigning a Free Float-Adjustment Factor:
MSCI defines the free float of a China A security as the proportion of tradable shares outstanding that are deemed to be available for purchase in the public equity markets by domestic investors. In practice, limitations on free float available to domestic investors also include strategic and other shareholdings that are not considered part of available free float. MSCI free float-adjusts the market capitalization of each security using an adjustment factor referred to as the Domestic Inclusion Factor (DIF).
Index Inclusion Factor:
Index Inclusion Factors were used to manage the indexes throughout the transition. The table below provides some examples of Index Inclusion Factors for companies through the phases of the transition. The index market capitalization of securities was determined as Index Inclusion Factor*Domestic Inclusion Factor*Security Full Market Capitalization.
For example, say companies A, B, C and D are current constituents of the MSCI China A Index. Company A continues as a constituent of the MSCI China A Index under the MSCI GIMI methodology. It will have an Index Inclusion Factor of 1 throughout the transition. Whereas Company B is not eligible for inclusion in the MSCI China A Index under the GIMI
methodology. It will be marked for removal from the MSCI China A Index and an Index Inclusion Factor of 0.5 will be applied to it during the first phase of transition. In the second phase the Index Inclusion Factor will be reduced to 0 indicating a complete removal of the company from the MSCI China A Index. In another case, company C is identified for removal from

the MSCI China A Index under the MSCI GIMI methodology but when it is evaluated at phase two and it becomes eligible for inclusion. In this case, the Index Inclusion Factor of company C for the first phase and second phase will be 0.5 and 1 respectively. Next, company D qualifies to remain in the MSCI China A Index in the first phase but fails to qualify for inclusion in the second phase, the Index Inclusion Factor will be 1 for the first phase and 0 for the second phase.
Moving on to company E, F and G which are not current constituents of the MSCI China A Index. Company E qualifies for inclusion to the MSCI China A Index throughout the transition. It will have an Index Inclusion Factor of 0.5 in the first phase and 1 in the second phase. Next, company F is identified as a new addition in the first phase, but fails to qualify to remain in the index in the second phase. Its Index Inclusion Factor of 0.5 in the first phase will be changed to 0 in the second phase. Lastly, company G is not eligible for inclusion in the first phase but subsequently becomes eligible for inclusion in the in the second phase, its Index Inclusion Factor will be 0 for the first phase and 1 in second phase.
Currently, the index market capitalization of securities in the enhanced MSCI China A Index is determined as Domestic Inclusion Factor * Security Full Market Capitalization as in the MSCI Global Investable Market Indexes.
