In the price adjustment for rights issues, the payment amount used to calculate the theoretical stock price was handled on an incorrect unit basis for issues whose allotment ratio is not 1:1. The adjustment factor (AdjFactor) and adjusted prices have been corrected. In addition, rights issue adjustments had been applied to some foreign stocks and issues listed on TOKYO PRO Market, which are excluded from price adjustment; these adjustments have been removed (AdjFactor = 1). Unadjusted values and adjusted trading volumes are not affected. Historical files for file download (CSV download / Bulk API) have also been replaced with the corrected versions.
