Informative Notice – 20231012 FTSE_JSE Index Harmonisation FAQ
To: Market Participants
From: FTSE/JSE Index Team
Date: 12 October 2023
Subject: FTSE/JSE Index Harmonisation FAQ
1. What is Index Harmonisation?
This is a project that was initiated by FTSE/JSE through client consultations commencing in 2019. The project will
ultimately collapse the vanilla and SWIX indices into one set of benchmark indices, significantly simplifying the
current benchmark complexity and overlap, and centralising liquidity. The project will be implemented in two
phases, with the first effective from the March 2024 review.
2. What are the ??vanilla?? indices and the SWIX indices?
The vanilla indices include the FTSE/JSE All Share Index (J203) and FTSE/JSE Top 40 Index (J200), as well as all of
their industry, sector, total return and capped variants. For each vanilla index, there is also currently a SWIX
(Shareholder Weighted) variant, such as the FTSE/JSE SWIX All Share Index (J403) and FTSE/JSE SWIX 40 Index
(J400).
3. How will Phase 1 of Index Harmonisation be implemented in March 2024?
The implementation will be done through the free float change of any constituent that uses a different free float
in the vanilla and SWIX indices. The constituent free floats in the vanilla indices will be changed to the same value
that??s used in the SWIX indices, resulting in weighting changes to the vanilla indices and no change to the SWIX
indices. Post the methodology alignment, the free float calculation will be standard across all the indices and will
be based on the lesser of the company breakdown and shares on the local Strate register. This means that all
constituents will use their SWIX Free Float.
There will be no change to any index codes or index names, nor will any indices be terminated or rebased in March
2024.
4. Why harmonise the methodology of the indices?
The process of harmonisation has been naturally occurring over the last few years. FTSE/JSE has observed a decline
in the number of ??Grandfathered?? companies in the All Share Index, with the latest events being BHP Billiton as a
result of the unification corporate action and Compagnie Richemont as a result of the termination of the South
African Depository Receipts (SADR) programme. The challenge faced now is that there are currently two
benchmark indices, whose constituent weights have converged over time, with the difference in constituent
weights mainly due to the remaining ??Grandfathered?? companies. The treatment for grandfathered companies is
not consistent with the index treatment for other foreign companies, and in short, these companies are
Page 1 of 10
inappropriately upweighted relative to comparable companies. The harmonisation project is designed to address
these challenges.
5. Which constituents will be affected by Index Harmonisation?
All constituents that use a different free float in the All Share Index (ALSI) and Shareholder Weighted All Share
Index (SWIX ALSI). The affected constituents are provided in the table below, however these may change closer
to the implementation date of the methodology change.
Alpha ISIN Instrument J203 FF J403 FF
AGL GB00B1XZS820 Anglo American 90.68% 29.90%
*ANG ZAE000043485 Anglogold Ashanti 99.96% 96.82%
ATT ZAE000177218 Attacq Limited 93.40% 93.37%
INP GB00B17BBQ50 Investec PLC 87.92% 53.32%
MNP GB00B1CRLC47 Mondi Plc 99.83% 41.65%
NTC ZAE000011953 Netcare 99.94% 99.59%
TGA ZAE000296554 Thungela Resources 97.55% 75.44%
Table 1: List of companies using a different free float in the ALSI and SWIX ALSI Indices
* ANG will be treated as foreign for index purposes and will use the Shareholder Weighted free float in all the FTSE/JSE indices effective from
the December 2023 review.
6. What impact will the methodology change have on vanilla index users?
The full list of the impact to each index is included in Appendix A however for illustrative purposes, the RESI10 will
be used to demonstrate the impact. If a client tracks or uses the J210 for any other purpose, this is what their
portfolio is estimated to look like before and after the March 2024 review:
Alpha ISIN Instrument J210 FF Weight JSZ0 FF Weight Weight Change
AGL GB00B1XZS820 Anglo American 90.68% 41.0% 29.90% 18.7% -22.3%
GFI ZAE000018123 Gold Fields 98.45% 13.2% 98.45% 18.3% 5.1%
SOL ZAE000006896 Sasol 90.95% 9.5% 90.95% 13.1% 3.6%
ANG GB00BRXH2664 AngloGold Ashanti Plc 99.96% 9.3% 96.82% 12.5% 3.2%
BHG AU000000BHP4 BHP Group Ltd 3.77% 6.6% 3.77% 9.2% 2.6%
GLN JE00B4T3BW64 Glencore 5.49% 5.6% 5.49% 7.7% 2.1%
SSW ZAE000259701 Sibanye Stillwater 98.83% 4.9% 98.83% 6.8% 1.9%
IMP ZAE000083648 Impala Platinum Hlds 88.95% 4.7% 88.95% 6.5% 1.8%
NPH ZAE000298253 Northam Platinum Holdings 90.76% 2.6% 90.76% 3.6% 1.0%
AMS ZAE000013181 Anglo American Platinum 21.25% 2.5% 21.25% 3.5% 1.0%
Table 2: Impact of methodology change on RESI10 constituent weights
7. What impact will the methodology change have on SWIX index users?
There will be no impact to users of the SWIX indices in March 2024.
8. What happens to an index tracker of both a vanilla index and its SWIX variant?
For the March 2024 phase of the project, there will be no impact to users of the SWIX Indices as well as indices
that use the SWIX Free Float, e.g. the Responsible Investment Index (J113). Clients that track the vanilla indices
will see slightly more free float changes in March 2024 as a result of a select few companies switching their current
free float to a SWIX Free Float. Index trackers of vanilla and SWIX variant indices will therefore have identical
indices in terms of constituents, constituent weights and index returns from March 2024.

9. Will there be an alignment of index values?
No, the vanilla index values won??t be aligned to the SWIX index values in March 2024, nor will the SWIX index
values be aligned to the vanilla index values.
10. Are the churn / turnover numbers expected to be high in March 2024?
It is unlikely that the churn numbers will reach record levels for the methodology change. This is because a large
number of companies have already switched to using their SWIX Free Float due to recent corporate actions. The
most notable turnover numbers were seen when Compagnie Financière Richemont (CFR) terminated their SADR
programme and secondary listed ??A shares?? on the JSE. The table below shows some of the historical churn
numbers. The December 2023 churn numbers as a result of the December review and ANG corporate action will
be published in the Notes from the December 2023 Advisory Committee meeting.

Table 5: Estimated March 2024 Index churn due to methodology change
11. What happens if there is a difference in constituents in tradable indices between now and
March 2024?
Currently, the vanilla indices and their SWIX variants have the same set of constituents. In the event that a vanilla
index has a different set of constituents to its SWIX variant, FTSE/JSE will make a once off adjustment to align the
vanilla constituents to the SWIX constituents. As an example, if the Resources 10 Index (RESI10) and Shareholder
Weighted Resources (SWIX RESI10) have a different set of constituents between now and March 2024, there will
be an adjustment made to the RESI10 to delete the constituent that??s not in the SWIX RESI 10 and add the one in
the SWIX RESI 10 in order to align the constituents. This means that effective from the March 2024 review, all
constituents and constituent weights in the vanilla indices and their SWIX variants will be identical.

12. Will FTSE/JSE introduce new indices with different capping levels?
No, at this stage there are no intentions to introduce new indices with different capping levels. Furthermore, the
capping levels in the current indices will remain as is until such a time that a change is deemed necessary. FTSE/JSE
will provide sufficient notice should this be the case.
