Among California's 400 largest public companies, 92 have no women among their highest-paid executives and board members, according to an annual report from University of California-Davis and women's leadership organization Watermark.

Silicon Valley is one of the worst culprits when it comes to lacking gender diversity. A third of those 92 companies are located in Santa Clara County, which contains Palo Alto, Mountain View and other cities and suburbs known for high concentrations of major tech companies. Among companies with no representation of women in top ranks statewide are TiVo in San Jose, Sketchers in Manhattan Beach, and security firm Palo Alto Networks in San Jose.

The report shows some improvement in representation nonetheless: Women now make up 12.3 percent of executive positions and board seats in the state. It's an increase of less than a percentage point over last year, but includes some bright spots. The software sector has seen an increase in the percentage of women directors from 8.7 to 15.5 percent since 2010, and hardware has seen an increase from 8 percent to 13.8 percent.

The report includes a new Watermark Index for Bay Area companies with the highest percentages of women in top ranks. Yahoo!, Zendesk and other major tech companies made the list. Four of the 11 companies on the list are in San Francisco.
