Nayar said Sampark would shut down by 2025 -- a kind of self-imposed expiry date -- and its contributions will stay even after the last rupee in the endowment is spent.
Nayar, who has been named on Forbes Asia's Annual Heroes of Philanthropy list for the second time, had earlier served as chief of IT major HCL Technologies and set up the Sampark Foundation along with his wife Anupama.
He added: "This is a different experiment. It's like this: If you knew you had only three months to live, you'll live your life differently."
The Sampark Foundation was started in 2005 by the Nayars. The Sampark Smart Class Program today covers 3 million children studying in 50,000 schools in Uttarakhand, Jammu & Kashmir and Chhattisgarh, making it one of the world's largest primary school transformation initiatives by a Foundation.

The goal of the Foundation, according to its website, is to significantly improve quality of education for 10 million children by 2020. The Nayars have committed Rs 650 crore to promoting the cause of transformative learning through frugal innovation in government schools in India.
"If you are an innovator, you need to innovate and test old rules of management -- internally and externally," Nayar said.
