Tesla Inc. will bid farewell to longtime directors and reduce the size of its 11-member board to nine as the automaker ushers in a new era of corporate governance. Director terms will be cut to two years from three, allowing shareholders to vote on the board\u2019s performance with greater frequency, according to a proxy filed Friday. Directors Brad Buss, former chief financial officer of Solarcity Corp., and Linda Johnson Rice, chief executive officer of Johnson Publishing Co., won\u2019t seek re-election when their terms expire at the June 11 annual shareholder meeting. If shareholders vote to reduce director terms to two years, venture capitalist Stephen Jurvetson - who returned from an extended leave of absence this month - has indicated he would not seek re-election in 2020. Antonio Gracias, a private equity firm founder, has also indicated he wouldn\u2019t stay on Tesla\u2019s board after his term ends next year.

Gracias and Jurvetson are both on the board of the billionaire\u2019s closely held SpaceX. \u201cIt strikes me as an important step towards more effective corporate governance,\u201d said Stephen Diamond, an associate professor of law at Santa Clara University. \u201cI would call this a board shakeup. The trio of Buss, Gracias and Jurvetson are the heart of the Musk crowd and the old boy network. Maybe this will bring some fresh air and light into the board.\u201d Jurvetson and Gracias should retire this June as opposed to waiting until 2020, said Dieter Waizenegger, executive director of CtW Investment Group, which works with union pension funds that are Tesla investors. Jurvetson went on leave in November 2017, and is just returning after being away for nearly 18 months, while Gracias faced some investor opposition last year. \u201cThis is a first good step, but there\u2019s more work to do,\u201d said Waizenegger. \u201cTesla should look for people who have really strong manufacturing expertise.\u201d Tesla is also proposing to eliminate the \u201cSupermajority Amendment,\u201d which requires the approval of two-thirds of shares to make certain major changes to the electric-car maker. Instead, a simple majority would suffice. The news, released on the afternoon of the Good Friday holiday when the U.S. stock market was closed, comes ahead of a busy week for the company. On Monday, Tesla will host an \u201cAutonomy Day\u201d for investors to showcase its progress with its driver assistance feature known as Autopilot. The company reports first-quarter earnings on Wednesday. Musk and the U.S. Securities and Exchange Commission have until April 25 to resolve their legal fight over the CEO\u2019s penchant for tweeting, after both said they needed more time. Tesla\u2019s other board members are chairman Robyn Denholm, Ira Ehrenpreis, Larry Ellison, James Murdoch, Kimbal Musk and Kathleen Wilson-Thompson. Ellison, co-founder of Oracle Corp., and Wilson-Thompson, global human resources chief at Walgreens Boots Alliance Inc., joined Tesla\u2019s board in December. Tesla shares have plunged 18 percent this year, compared with a 21 percent gain in the Nasdaq Composite.
