HSI Services Limited will introduce a series of Hang Seng China AH Indexes ("China AH Series") to help investors track the performance of those companies that have both mainland China-listed A shares and Hong Kong-listed H shares ("AHCompanies").

The China AH Series includes the Hang Seng China AH Premium Index ("AH Premium Index"), an index measuring the weighted average premium (or discount) of A-share prices to H-share prices of the constituents, as well as three price indexes that track the price performances of the different classes of shares of these AH Companies.

The China AH Series will initially comprise 27 constituents – the large AH Companies that have completed share reform when the indexes are launched.
