/KASE, March 31, 2026/ – Effective April 1, 2026, Kazakhstan Stock Exchange (KASE) will begin calculating and publishing the following stock market indices:

1) indices of the corporate bond market denominated in tenge with a credit rating of at least BBB-, assigned by international rating agencies (indices of the KASE_KZ3BUP* series):

- KASE_KZ3_CP – index of "clean" bond prices, calculated based on prices excluding accrued and unpaid coupon interest;

- KASE_KZ3_TR – the index of total bond income calculated based on prices taking into account accrued coupon interest and reinvested coupon payment;

- KASE_KZ3_Y – yield indicator, in percent per annum;

- KASE_KZ3_DUR – index duration, in years;

2) indices of the corporate bond market denominated in US dollars with a credit rating of at least BBB-, assigned by international rating agencies (indices of the KASE_US3BUP* series):

- KASE_US3_CP – index of "clean" bond prices, calculated based on prices excluding accrued and unpaid coupon interest;

- KASE_US3_TR – index of total bond income calculated based on prices taking into account accrued coupon interest and reinvested coupon payment;

- KASE_US3_Y – yield indicator, in percent per annum;

- KASE_US3_DUR – duration of the series index, in years.

The launch of the calculation of these indices is aimed at maintaining and developing interest in the corporate bond market with a high credit rating.

The formulas for calculating the KASE_KZ3BUP* and KASE_US3BUP* series indices are based on the current methodology for calculating KASE corporate bond indices using the standard approach for debt instruments. The weighted average price of one bond based on trades executed in the trading system will be used as the bond price for calculating the indices and indicators. If there are no trades involving bonds, the arithmetic mean between the highest bid price for the bonds and the lowest bid price for the bonds will be used.

The initial value of the KASE_KZ3_CP and KASE_US3_CP indices is fixed at 100.00 points, the initial value of the KASE_KZ3_TR and KASE_US3_TR indices is fixed at 100.00 points with the addition of the average value of the accumulated coupon interest (in percent).

Index values will be calculated once a day on weekdays at 17:30 Astana time and published on the KASE website in the section "Indices – Stock Market – Corporate Bonds" – see more

The corresponding amendments have been made to KASE's internal document "Methodology for calculating stock market indices and indicators" and will also come into effect on April 1, 2026.
