Dividend distribution policy requirement mandates disclosure by largest listed companies, detailing parameters and rationale for dividend decisions. The top five hundred listed entities by market capitalization must formulate a Dividend Distribution Policy and disclose it in their annual reports and on their websites, specifying circumstances for dividend expectation, financial parameters, internal and external factors, utilization of retained earnings, and parameters for different classes of shares; any additional or changed parameters must be disclosed with rationale. Other listed entities may disclose such a policy voluntarily.
