Large companies have seen significant board turnover in the past several months, capping off a year of increased focus from stakeholders on individual directors’ skill sets and board refreshment.

Companies also appointed a large number of directors with government connections. Some 80% of S&P 500 directors currently say they have government and/or regulatory relations experience, according to public company intelligence provider MyLogIQ.

For example, Consolidated Edison named Catherine Zoi, the CEO of EVgo and former assistant secretary for energy efficiency and renewable energy at the Department of Energy, to its board last month.
