recommended investors vote against ratifying the pay plan of

Tesla CEO Elon Musk at the electric carmaker's June 13

In a report sent by a representative late on Thursday the

Murdoch, but recommended votes for director Kimbal Musk and for

the company's proposed move to change its state of incorporation

to Texas from Delaware.
