Summary of investments at fair value
We account for the following investments at fair value on a recurring basis with adjustments to fair value recognized in gain/(loss) on investments within non-operating expense in our income statement. We recorded losses of $95 million and $199 million on our fair value investments during the three and nine months ended September 30, 2020, respectively. These results were driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in companies without publicly-traded shares.
