2026-10-03 MSCI ACWI v2026.03.31 → v2026.05.12 M5 Weighting and capping Editorial The update corrects a typographical error in the FIF/DIF change threshold band: the range previously read “between 5% than 25%” and now correctly reads “between 5% and 25%.” No threshold, eligibility condition, review timing, or other index rule is changed.
2026-10-03 MSCI ACWI v2026.03.31 → v2026.05.12 M7 Buffers and turnover control Editorial The updated section makes no substantive methodology change.

2026-10-03 MSCI ACWI v2026.03.31 → v2026.05.12 M4 Selection and constituent count Editorial The only change is the removal of an extra footnote marker string after "Interim Market Size-Segment Cutoff," changing "Cutoff20F20" to "Cutoff20."

2026-10-03 MSCI ACWI v2026.02 → v2026.03.31 M5 Weighting and capping Minor The update replaces the former two-band FIF rounding framework (above/below 15%, with 5% and 1% increments) with three free-float bands: above 25%, 5%-25%, and below 5%, rounded to 2.5%, 0.5%, and 0.1%, respectively.

2026-10-03 MSCI ACWI v2026.02 → v2026.03.31 M5 Weighting and capping Major The methodology for securities subject to foreign ownership limits has been simplified: foreign-investor free float is now the lesser of estimated free float and the unadjusted FOL.

2026-10-03 MSCI ACWI v2026.02 → v2026.03.31 M2 Universe Editorial The only change is to the superscript/reference marker attached to “Market,” changing “Market1” to “Market0F1.” No index construction, eligibility, selection, weighting, or other methodology rule is changed.

The fragmentary closing note is also changed from “Non-current IMI constituent” to “Non-current IMIT constituent.” The operative market-closure and suspended-security review rules are unchanged.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M9 Calculation and return variants Editorial The updated section makes no substantive change to the trading-suspension policy.

2026-10-02 MSCI ACWI v2026.02 → v2026.08 M3 Eligibility screens Minor The minimum foreign-room requirement itself is unchanged at 15%, but the updated section adds an India-specific eligibility restriction: securities on the NSDL/CDSL official list for which the Red flag or Breach limit has been reached would not be considered. In the supplied text, the inserted sentence is spliced directly into the following sentence beginning with “For a security.”
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M3 Eligibility screens Editorial The section was reworded to use the abbreviated trademarked terms "IMI™" and "GIMI™" instead of "Investable Market Indexes" and "GIMI." The liquidity thresholds, alternative-listing priority, Emerging Markets retention condition, and Liquidity Adjustment Factor rules were unchanged; footnotes were renumbered from 50–52 to 51–53.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M4 Selection and constituent count Minor The light-rebalancing addition rule narrows the exclusion for securities with extreme price increases. Under the updated methodology, such securities are ineligible only when their FIF is less than 0.75, whereas the previous text excluded all securities exhibiting extreme price increases. The abbreviation of "Investable Market Indexes" to "IMI™," footnote renumbering, and sentence relocation are formatting changes.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M7 Buffers and turnover control Major The light-rebalancing rule for Small Cap-to-Standard migration after an extreme price increase has been narrowed: the updated text makes ineligibility conditional on having a FIF below 0.75, whereas the previous text applied the bar to all existing IMI constituents exhibiting an extreme price increase. The explicit statement that such migrants would be retained as Small Cap constituents was removed and replaced by a cross-reference to the detailed treatment. Other edits are IMI naming/trademark changes, formatting, and footnote renumbering.

New additions will use the lower of (i) the higher of adjusted 13F ownership or capital-raising float and (ii) free float under the current MSCI Free Float Data Methodology. Existing constituents will transition in phases, with a midpoint adjustment in May 2026 and full application of the new approach from November 2026 if enhanced transparency remains unavailable.

2026-10-02 MSCI ACWI v2026.02 → v2026.08 M5 Weighting and capping Editorial The core free-float-adjusted market capitalization formula is unchanged, but the illustrative tables are revised. The non-FOL example adds a third company and changes sample FIFs and adjusted capitalizations; the FOL example now uses two companies, a "Rounded Free Float" line and 33.33% foreign ownership limits, while omitting the prior foreign-strategic-adjustment rows and the special footnote.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M5 Weighting and capping Minor The FIF methodology replaces the prior >15% / <15% split with three free-float bands: >25%, 5–25%, and <5%. Rounding changes to 2.5%, 0.5%, and 0.1% respectively, with the upper band now rounded to the nearest increment rather than rounded up, and FOLs are rounded to 0.1%. For securities with a LIF, both adjusted free float and FOL are now rounded to 0.1%, replacing the prior tiered 5%/1% treatment.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M5 Weighting and capping Minor For securities subject to foreign ownership limits, the methodology no longer adjusts the FOL downward for foreign non-free-float shareholdings. The foreign-investor free float is now the lower of the estimated free float and the unadjusted FOL, and the prior applicability note for countries where foreign room is not monitored was removed.

If new information emerges after that deadline but before the Index Review effective date, MSCI may make amendments on shorter notice to minimize turnover or avoid replicability issues.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The updated section abbreviates the index name to MSCI GIMI™ and adds footnote 33. The new footnote establishes a special minimum float-adjusted market capitalization requirement when a Standard Index constituent has a post-event FIF below 0.15, equal to two-thirds of 1.8 times one-half of the Standard Index Interim Size-Segment Cutoff.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The updated section renames MSCI Global Investable Market Indexes as “MSCI GIMI™” and inserts a line break, which are presentational changes.

The 50% increase and 33% decrease triggers, FIF and float-adjusted capitalization conditions, size-segment migration rules, and deletion criteria remain unchanged.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial The methodology title is abbreviated from “MSCI Global Investable Market Indexes Methodology” to “MSCI GIMI™ Methodology” (and subsequently “MSCI GIMI Methodology”).

No implementation thresholds, timing, deletion rules, or NOS/FIF treatment changes.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial The updated text replaces "Investable Market Indexes" with the abbreviated trademark form "IMI™ Indexes," adds a space before footnote marker 30, and includes the footnote reference directing readers to section 3.2.7 for significant IPOs.

2026-10-02 MSCI ACWI v2026.02 → v2026.08 M5 Weighting and capping Minor The FIF review replaces the prior single free-float change threshold of more than 1% for existing constituents with tiered thresholds based on the security’s free float: at least 2.5% for free float above 25%, 0.5% for free float from 5% to 25%, and 0.1% for free float below 5%. The exceptions to these thresholds are also revised to cover size-segment migrations, deletions from the IMI in connection with Micro Cap additions, and FOL-driven FIF changes, while retaining corrections.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M3 Eligibility screens Minor A new rule excludes existing IMI constituents with an extreme price increase and FIF below 0.75 from migration into the Standard Indexes. Their treatment depends on 1.8x market-capitalization cutoff tests: smaller constituents remain Small Caps, while larger constituents are deleted from the Small Cap Index, retained in the investable universe, and reconsidered at the next Index Review.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M5 Weighting and capping Editorial The section was renumbered and retitled as the minimum foreign-room requirement, with the general existing-constituent free-float buffer and extreme-price-increase paragraphs removed from this section as part of the split. The foreign-room adjustment factor, quarterly review, 12-month upward-adjustment waiting period, and related monitoring rules remain substantively unchanged.

The surrounding investability-requirements sentence is unchanged but split by the inserted footnote.
2026-10-02 MSCI ACWI v2026.02 → v2026.08 M7 Buffers and turnover control Major The update removes the footnote specifying different buffer-zone boundaries at “light” rebalancings: one half of and 1.8 times the Market Size-Segment Cutoff. The remaining changes are terminology, trademark, hyphenation, and footnote-placement edits and do not alter the standard 2/3 and 1.5 times buffer boundaries.

2026-10-02 MSCI ACWI v2026.02 → v2026.08 M4 Selection and constituent count Minor The updated document deletes footnote 20, which defined how the Interim Market Size-Segment Cutoff is calculated during an Index Review.

The main formula for the Initial Segment Number of Companies is otherwise unchanged.
