Perusing the latest round of statistics about women in high-ranking corporate finance jobs can be somewhat discouraging. There were just 44 women CFOs at Fortune 500 companies in 2010, unchanged from 2009. That disparity isn't limited to finance jobs at the top, of course. A recent study from research institute Catalyst shows women are underrepresented in the C-suite overall, holding 14.4% of executive officer positions in 2010. And the gap between the sexes in the business world starts early: in 2009-10, women made up just 38% of MBA graduates, according to AACSB International. However, the accomplishments of the outstanding women financial leaders, annually recognized by Treasury & Risk, serve as an inspiration and a reminder that perseverance and execution count. From issuing debt, negotiating new credit facilities and integrating acquisitions, to de-risking a pension plan and designing a new commodity hedging facility, these women in finance are doing the work that will make a difference to their companies, and to the economy as a whole.
