Vindhya Telelinks has launched a 100-day "Saksham Niveshak" campaign, an initiative to help shareholders update their KYC details and claim unpaid or unclaimed dividends. Following guidelines from the IEPFA, this program is crucial to prevent shares from being transferred to the Investor Education and Protection Fund Authority. Shareholders holding physical shares should update their details with the Registrar and Share Transfer Agent, while those with demat shares need to update their Depository Participant. Details regarding unclaimed dividends for the past seven years are available on the company's website.
