Dividend Policy

With respect to dividends from retained earnings, Sumitomo Seika Chemicals Co., Ltd. considers “returning profits to shareholders” as one of its priority management issues and makes it a basic policy to determine dividends, after giving due consideration to stable dividend payment and securing of internal reserves to prepare for future business development, based in principle on the dividend payout ratio of 30% or more and the dividend on equity (DOE)* ratio of 4.5% or more. The Company will allocate internal reserves to growth investments and strengthening its business foundation.

• A dividend on equity (DOE) ratio is total dividends divided by shareholders’ equity at the end of the previous fiscal year. Shareholders’ equity at the end of the previous fiscal year refers to the amount obtained by excluding the cumulative other comprehensive income (such as foreign currency translation adjustment, other valuation differences, deferred gains or losses on hedges, and cumulative adjustments related to retirement benefits) from the total net assets at the end of the previous fiscal year.
