II. Index Calculation
1. Outline
・ JPX-Nikkei 400 is calculated using free-float adjusted market value weighting. The
index is denominated in points and is calculated to the second decimal place (values
beyond the second decimal are rounded).

2. FormulaIndex =
CMV = Current market value

CMV
× Base PointBMV

BMV = Base market valueMarket Value = ෍(Number of Shares for Each Constituent

× Stock Price for Each Constituent)

3. Stock Price Used for Calculation

・ The stock prices used for calculating JPX-Nikkei 400 is determined by the following
order of priority:(1) Special Quote or Sequential Trade Quote, (2) Contact Price, (3) Base Price forIndex Calculation when neither (1) or (2) are available (determined in the following
order: (1) Theoretical Ex-rights Price, (2) Most Recent Special Quote or Sequential
Trade Quote on or before the previous trading day, (3) Most Recent Contract Price
before the previous trading day.)4. Number of Shares Used for Index Calculation
・ The number of shares used for index calculation is determined by multiplying the total
number of listed shares by the free-float weight ratio following cap-adjustment (FFW).
Number of Shares Used for Index Calculation for Each Stock= Total Number of Listed Shares × FFW Ratio following cap-adjustment
・ The number of listed shares used for index calculation is the number of shares obtained
5
Copyright © 2018- by Tokyo Stock Exchange, Inc. and Nikkei Inc. All rights reserved

(Reference Translation)

through processes specially arranged for index calculation, based on the number oflisted shares. Regularly, the number of each issue's listed shares used for index
calculation is equivalent to that of each issue's outstanding shares, however, in the caseof a stock split, for example, a temporary difference could occur between the two figures.
This is because the number of listed shares changes on the listing change date, while
the number of listed shares for index calculation changes on the ex-rights date.
・ FFW ratio used in JPX-Nikkei 400 shall be the FFW ratio after cap-adjustment (free float
weight ratio x cap-adjustment ratio) with a maximum 1.5% constituent ratio based onmarket capitalization weight on the periodic selection base date. In cases where the cap
maximum is exceeded following periodic selection, the cap-adjustment ratio shall not bealtered until the periodic selection application date of the following year.
・ However, in cases where there is a remarkable change in the constituent weight due to,for example, periodic review of the free float weight described below or corporate
consolidation, merger, acquisition, etc. of a JPX-Nikkei 400 constituent, an extraordinary
revision of the cap-adjustment ratio of constituents may be conducted.

5. Free Float Weight(1) Outline
・ Free-Float Weight (FFW) is the percentage of listed shares deemed to be available fortrading in the market. The Index Provider calculates FFW for each listed company anduses this value in index calculation. The FFW of Company A may be different from thatof Company B.

・ FFW is calculated by first estimating the number of non-free-float shares (listed shares
deemed not to be available for trading in the market) using securities reports and otherstatutory documents required by the Financial Instruments and Exchange Act, as well as
publicly available documents released by each listed company. Next, the non-FFW ratio(Non-free-float shares / total listed shares) is calculated, then FFW is obtained bysubtracting the non-free-float factor from 1 (1 – Non-FFW). FFW is expressed as a
figure in the range of 0.00000 to 1.00000 in increments of 0.00001.
・ FFW is reviewed once a year in order to reflect the latest share ownership distribution.
The timing of the FFW review varies depending on when earnings are announced. In
addition to the periodic review, extraordinary reviews are conducted if FFW changes
6

(Reference Translation)

significantly due to events such as allocation of new shares to a third party.

(2) Periodic Review
・ The announcement date and effective date of the periodic FFW review varies according
to when listed companies announce earnings as below:
Settlement Term

Announcement Date

Effective Date*

January - March

Last business day of January

July - September

October - December

Fifth business day of July

Last business day of July・ *Adjustments will be made before markets open.

・ At the periodic review, FFW is rounded up to the nearest 0.05 as below after subtracting
the non-FFW ratio from 1 (1 – Non-FFW).
・ FFW for periodic review

Allocation of new shares to a third party, conversion of preferred shares or exercise ofsubscription warrants, company spin-off, merger, acquisition, take-over bid (TOB) andother events deemed applicable by the Index Provider.

(4) Estimation of non-free-float sharesa. Documents
Securities reports and other statutory documents required by the Financial
Instruments and Exchange Act as well as the publicly available documents released
by listed companies are used to estimate the number of non-free-float shares.

split; the number of shares calculated based on ratios for stock splits, reverse splits, paid-in allotment
to shareholders, etc. is different than the final number of shares determined after the effective date; orrevisions made by listed companies after data has been reflected in index calculation.
*6: Base market value (BMV) is not adjusted in the case of a stock split or reverse stock split as thedecrease or increase in share price corresponds to the change in the number of listed shares, andthe market capitalization remains unchanged.

(3) Data Source
・

Information on the reason for base market value adjustments, details on theadjustment, the adjustment date and other data is available through the “Sho-ho”(TSE Notice) published daily by TSE based on reports, etc. submitted by issuers.
(Please refer to the Section II 5. for information on calculating FFW.)・

If an issuer revises the contents of a previously published report that resulted in an
index adjustment, retroactive index adjustments will NOT be made based on therevised contents.

Adjustment Method(1) Indices that do not reflect dividends (i.e. price indices)
i. Adjustment Method
・ The base market value will be adjusted according to the formula below in order tomaintain the continuity of the index:
Previous Business Day Market Value
Old Base Market Value (Before Adustment) − Adjustment Base Market Value=*Adjustment Amount(Previous Business Day Market Value ± Adjustment Amount)
New Base Market Value (After Adjustment)＝

Increase (Decrease)in Number of Shares Used for Index

Calculation x Stock Price Used for Adjustment
Therefore,
New Base Market Value ＝(Old Base Market Value×(Previous Business Day Market Value±Adjustment Amount))/(Previous Business Day Market Value)

ii. Adjustment Example
・ If, for example, the old base market value is 20 trillion yen and the previous day’s
market value is 400 trillion yen, the index value on the previous day will be:
Previous Day's Index ＝ ¥400 tn ÷ ¥200 tn ×10,000＝ 20,000.00

・Now, suppose that the number of listed shares of Stock A used for index calculation
increases by 100 million shares due to a public offering. If its closing price on theprevious day was ¥2,000, the adjustment amount is 100 million shares x ¥2,000 = ¥200
billion. The new base market value, therefore, is:
New Base Market Value＝ ¥200 tn ×(¥400 tn ＋ ¥200 bn）÷ ¥400 tn＝ ¥200.1 tn

・ As illustrated below, if there is no price change in any constituent, the value for theindex today is the same as the previous day: 20,000 points. Thus, continuity in the index
is maintained though adjustments to base market value even if the market value of
constituents changes due to public offering.
(¥400 tn + ¥200 bn)÷¥200.1 tn ×10,000 = 20,000 points(2) Total Return Index
・ Dividends used in calculating the Total Return Index are gross (i.e. before tax)・ Since the dividend amount for the current period is not fixed as of the ex-dividend date,adjustments made to reflect dividends in the base market value are made in twostages: 1) adjustment using estimated dividends and 2) minor adjustments made toreflect differences between estimated dividends and the dividend amount announced
in the earnings report.
a. Adjustments Using Estimated Dividends
・ The total dividend amount for all constituents is calculated on ex-dividend dates using
estimated dividends, and the base market value is adjusted as above. In principle, theestimated dividend amount used is as follows:i.

Dividend amount for the current period as announced in timely disclosure
documents, if available.

(Reference Translation)ii.

Dividend amount for the previous period if the dividend for the current period is not
fixed (e.g. the dividend is not announced in disclosure documents as i. above, orthe amount is not determined, etc.)

・ The base market value adjustment method is basically as described in the previous
section, except an adjustment is made to reflect dividends as follows:
New Base Market Value ＝
Old Base Market Value × (Previous Business Day Market Value − Total Dividends ± Adjustment Amount)
Previous Business Day Market Value*Dividends per Constituent = Number of Shares Used for Index Calculation on Business
Day Before Ex-Dividend Date × Estimated Dividend Per Share*Total Dividends = Sum of Dividends for All Constituents*Adjustment Amount ＝ Increase (Decrease) in Number of Shares Used for Index
Calculation × Share Price Used for Adjustment
b. Minor Adjustment to Reflect Difference Between Estimated and Actual Dividends
・ Minor adjustments are made with respect to those constituents for which the estimateddividend used on the ex-dividend date and the dividend announced in the earnings
report are different. Specifically, the total dividend adjustment amount is calculated on
the 7th day of the 3rd month after the ex-dividend date (or the previous business day if
the 7th day falls on a holiday), and the base market value is adjusted using that amount.
(For example, for companies that announce earnings in March, the adjustment is madeon June 7th.)・ Data used to calculate the adjustment amount is the information available as of threebusiness days before the adjustment date. However, if a dividend adjustment isannounced outside of this timeframe and the Index Provider deems that the adjustment
will have a significant impact on the index value, an additional minor adjustment will be
made.
New Base Market Value ＝
Old Base Market Value × (Previous Business Day Market Value − Total Adjusted Dividends ± Adjustment Amount)
Previous Business Day Market Value

(Reference Translation)* Adjusted Dividend per Constituent = Number of Shares Used for Index Calculation
on Business Day Before Ex-Dividend Date × (Dividend Announced in Earnings
Report - Estimated Dividend per Share)* Total Adjusted Dividends = Sum of Adjusted Dividends for All Constituents* Adjustment Amount ＝ Increase (Decrease) in Number of Shares Used for Index
Calculation × Stock Price Used for Adjustment(3) Net Total Return Index
・ In addition to the Total Return Index explained above, the Net Total Return Index whichreflects the tax rate applied to constituent stock dividends is also calculated.
・ The base market value adjustment to reflect the dividend amount is made at the same timeas (2). But when calculating the base market value, the "total dividend amount" and the"total dividend minor adjustment amount" shall each be multiplied by (1 minus the dividend
tax rate).

・ The tax rate used in calculating the Net Total Return Index is withholding tax rate forlisting shares (except for the local tax) at the adjustment date.
