Women CEOs are outnumbered. And official data show their median salary is more than a third less than that of their male counterparts.
But that has not fazed Ms Wong Su-Yen, chief executive of consultancy Bronze Phoenix, which she formed last year.
She says: "Remuneration is a function of many factors, including company size, industry and geographic scope. The large gap in this instance could be driven, for example, by a higher concentration of male chief executives in higher paying industries, or larger companies."
