Convertible notes634 131 852 323 

The fair values of our convertible notes were determined based on Level 2 inputs, including the trading price of our convertible notes when available, our stock price, and interest rates based on similar debt issued by parties with credit ratings similar to ours. The fair values of our other debt instruments were estimated based on Level 2 inputs, including discounted cash flows, the trading price of our notes when available, and interest rates based on similar debt issued by parties with credit ratings similar to ours.

Other operating (income) expense, net included unrealized losses primarily from semiconductor equipment held for sale of $71 million and $82 million in 2020 and 2019, respectively. The fair values were based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment (Level 3). Assets held for sale were not significant as of the end of either period reported.
