The all-male board is officially a thing of the S&P 500's past.
Copart, the last company in the index without a female director, appointed CyrusOne CFO Diane Morefield to its board of directors this week. Earlier this year, Skechers and TripAdvisor also added women.
The final stretch of progress has been slow. In 2000, about 86% of S&P 500 companies had at least one women on their board according to Spencer Stuart. The last 14% of companies have taken almost 20 years to close the gap.
