The California State Teachers’ Retirement System hired a coordinator to shepherd its effort with other big U.S. investors to engage gun manufacturers and sellers to make firearms safer and expand the coalition.

Michael Weston started May 13 as public engagement manager. Weston, 48, came from the California Department of Social Services, where he spent 13 years, most recently as deputy director of public affairs and outreach programs. Previously he worked in television news.

As the world’s largest educator-only pension fund, the California State Teachers’ Retirement System, or CalSTRS, embodies a century-long pledge to uphold the state’s promise of a secure retirement to teachers.

CalSTRS’ dedication to act as fiduciaries on behalf of California’s teachers requires that we correct the record to assure our members, stakeholders and the public that the CalSTRS Funding Plan is working and to argue strenuously for the defined-benefit pension as the best choice for career educators.

In a Worldwide Exchange exclusive, CalSTRS Chief Investment Officer Christopher Ailman says companies like Uber and Lyft are facing questions from investors for good reason. Ailman also shares his investment outlook and discusses the state of U.S. public pensions.

That’s essentially what founders Logan Green and John Zimmer are telling investors who buy stock in the company’s initial public offering, expected next week.

After the offering, Green and Zimmer together will own just under 5 percent of the company’s stock but control 49 percent of the company’s votes, according to data in the company’s prospectus.

CalSTRS has been the great exception among California public pension systems, different from the others in two important ways. The state helps pay some of its pension costs, and the board lacked the power to set employer rates, needing legislation instead.

The upper ranks of hedge funds are almost exclusively white and male. Impactive Capital LP, a new activist fund being launched by two industry veterans, will be one of the exceptions.

Its co-founders and managing partners are Christian Asmar, who is Hispanic, and Lauren Taylor Wolfe. Both spent roughly a decade at activist hedge fund Blue Harbour Group LP before leaving to strike out on their own.

The board of the California State Teachers’ Retirement System (CalSTRS) has approved plans to add a second office tower alongside it 17-story headquarters building in West Sacramento, part of a $300 million campus expansion aimed at attracting new investment staff and other workers.
