Lenovo, the world’s top PC manufacturer, is adding Yahoo co-founder Jerry Yang to its board of directors.

Yang, who turns 46 in November this month, has served as an observer to the board since February of 2013. 

Lenovo made the announcement early Thursday in Hong Kong where it also disclosed its quarterly earnings.

“Jerry has made great contributions since becoming a board observer, and we are honored that now he will be a full member of our Board of Directors,” said Yuanqing Yang, Chairman and CEO of Lenovo Group, the parent of Lenovo.

“Jerry’s proven track record as an entrepreneur, his unique global perspective, and his pioneering spirit as one of the great innovators of the Internet era are all qualities that we value at Lenovo. Jerry will remain an important voice in our boardroom as we continue to build Lenovo into a diverse, well respected global technology leader.”

Yang led Yahoo as CEO from 2007-2009 and served on the company’s board from its founding in 1995 through 2012.

He also is a board member of China-based technology giant Alibaba as well as Workday. From 2000-2012 he was a director for Cisco.

Lenovo’s board now includes representatives from four countries (China, the United States, the United Kingdom, Japan) and Hong Kong, where its shares are traded.
