Forbes magazine on June 1 reduced its estimate of the net worth of Elizabeth Holmes, the founder and chief executive of health technology company Theranos Inc, to zero from US$4.5bil (RM18.71bil) last year. 

Holmes' blood-testing company has been under investigation by several federal and state agencies and was accused in a suit filed last week of endangering customer health through "massive failures" that misrepresented the accuracy and quality of its blood tests, according to court papers.
