Investments	4. Investments At March 31, 2021, we held a $5.0 million investment consisting of 353,604 shares in TuSimple, a self-driving technology company. Effective April 15, 2021, TuSimple completed their initial public offering at a closing price of $40.00 per share. As we now have a readily determinable fair value based on quoted market prices, which makes this a Level 1 fair value measurement, we adjust the investment to fair value at each reporting period. During the three months ended March 31, 2022 we recognized an unrealized loss of $8.4 million in other expense, within the unaudited condensed consolidated statements of comprehensive income (loss). The fair value of the investment is $4.3 million and is included in other noncurrent assets on the accompanying unaudited consolidated balance sheets.
