US women ‘may not reach boardroom parity’

Women, who make up half the American workforce, may be 40 years or more from parity with men on US corporate boards, the US Government Accountability Office said in a new report.

About 23% of open seats in the Standard & Poor’s 1500 Index went to women in 2014, according to the GAO.

If that figure rose to about 50% - or half of all openings - boards would be evenly split between women and men by roughly 2055, the report said.
