AMP's male only board one of four outliers as gender diversity improves

AMP's male-only board has been outed as the latest gender diversity survey shows women now account for 29.7 percent of ASX 200 board positions. 

Australian Institute of Company Directors chief executive Angus Armour says Australia is the first country in the world to achieve the 30 percent target without quotas or regulatory intervention. 

Other companies with no women on their boards include TPG Telecom, ARB Corporation and Emeco Holdings.
