Billionaire investor Ron Baron, a long-time shareholder and bull of Tesla, wrote a public letter supporting Elon Musk's controversial $56 billion compensation package. Baron notes the 2018 package included ambitious performance metrics that few believed could be achieved, and Musk would have earned nothing without meeting them. Baron calls Musk the "ultimate ‘key man’ of key man risk" and credits his drive for Tesla's success. Baron has seen about 20 times the returns on his Tesla investment since 2014, with the stock as the largest holding in his fund. If approved, the pay package would be the largest in corporate America if approved.
