Uber's series of scandals have finally started to affect the company's value, the Wall Street Journal reports. Four mutual funds that have invested in the app-based taxi company have marked down their stakes in it by as much as 15%, according to The Journal. Together the moves represent the first major set of markdowns to hit the company, which has faced near-continuous turmoil since late last year. Uber's stock, which is privately held, had been valued at $48.77 per share since late 2015.
