Turns out not everyone was in the dark about Elon Musk's plans to take Tesla private. A post from the board on the electric-vehicle manufacturer's investor relations site says the idea came up last week during a board meeting. "This included discussion as to how being private could better serve Tesla's long-term interests, and also addressed the funding for this to occur." So, in theory, the entire board went along with CEO Musk's sophomoric pot reference stock-buyback price. The brief post concludes that the board has met several times since to evaluate the move.
