Our investment in Lyft, Inc. (Lyft) is estimated at fair value using Level 3 inputs because the investment is subject to transfer restrictions. The fair value of our investment in Lyft at March 31, 2019 uses Lyft’s quoted market price, less a discount for the lack of marketability due to the restriction from selling our shares until September 26, 2019. The estimated volatility of Lyft’s common stock represents the significant unobservable input to the put option pricing model used to derive the fair value of our investment. The fair value of this investment was $1.2 billion and $884 million in Other assets at March 31, 2019 and December 31, 2018. We recorded an unrealized gain of $285 million in Interest income and other non-operating income, net in the three months ended March 31, 2019. Refer to Item 3.
