The Standard & Poor's 100 index and the Silicon Valley 150, a list compiled by Fenwick & West, have some overlapping companies but many diverging corporate governance trends, a new survey finds.

David Bell, the Fenwick partner who authored the firm's 2018 Corporate Governance Practices and Trends report, said the continuation of dual-class voting structure trends in the SV 150 stood out to him.

The survey found 13 percent of SV 150 companies had dual class structures, an increase from last year, compared with 9 percent of S&P 100 companies.
