Here's how Nobel laureate Malala Yousafzai's book brought her fortune

Nobel Laureate Malala Yousafzai and her family have become millionaires as a result of income from her memoir describing life under Taliban rule in Pakistan's picturesque Swat valley and appearances on the lecture circuit around the world, according to a PTI report.

A company named Salarzai Ltd which was set up to protect the rights to her life story had 2.2 million pounds (around $2.94 million, or Rs 19.9 crore) in the bank by August 2015 and made a pre-tax profit of 1.1 million pounds. Malala, her father Ziauddin Yousafzai, and her mother Toor Pekai are joint shareholders of the company, 'The Times' reports.

The book has sold at least 1.8 million copies worldwide which includes 2,87,000 copies in the UK which amounts to 2.2 million pounds, according to Nielsen Book Research. The book was published in October 2013 by Weidenfeld & Nicolson in the UK in a deal reported to be worth about 2 million pounds.

The book called 'I am Malala' is about the 18-year-old Pakistani teenager's life, who managed to survive a shot to the head by a Taliban gunman and relived the incident and her life in the Swat Valley. She was shot while travelling home from school on the bus with her friends. The book was co-written with Sunday Times journalist Cristina Lamb.

Malala is the youngest recipient of the Nobel Peace Price. She and her family are now based in Birmingham where she attends Edgbaston High School for Girls.

Malala is one of the highest-earning Nobel laureates as her speeches bring her 114,000 pounds, according to research by Institute for Policy Studies in the US. Another world famous Nobel laureate Desmond Tutu earns 64,000 pounds through his speeches.
