Amazon is making changes to its search for members of its board.

The company announced in a public filing on Monday that they will include more “women and minority” candidates when looking for new board members, CNBC reports.

“This policy formalizes a practice already in place,” Amazon said in a statement to CNBC.

Shareholders had expressed displeasure over the retail giant’s lack of diversity in its board. CtW Investment group wrote a letter to the company’s board last month wanting them to adopt the “Rooney Rule,” which would make it a requirement for Amazon to include women and minority candidates when looking for director candidates.

The board rejected the rule saying that they already look for “candidates with a diversity of experience and perspectives, including diversity with respect to race, gender, geography, and areas of expertise,” according to CNBC.

Only three women sit on Amazon’s board, per the report.
