From the 8K (please ignore the stock manipulation efforts by TruthSetter):
On September 4, 2018, Tesla’s Chief Accounting Officer, Dave Morton, provided notice that he was resigning from Tesla, effective immediately. Dave stated: “Since I joined Tesla on August 6th, the level of public attention placed on the company, as well as the pace within the company, have exceeded my expectations. As a result, this caused me to reconsider my future. I want to be clear that I believe strongly in Tesla, its mission, and its future prospects, and I have no disagreements with Tesla’s leadership or its financial reporting.”
Tesla’s accounting functions and personnel will continue to be overseen by both Tesla’s Chief Financial Officer and its Corporate Controller, as had been the case prior to and during Dave’s transition to Tesla.
