Fair Value Measurements

Substantially all of our marketable debt and equity investments were classified as available-for-sale and carried at fair value. Amounts reported as cash and equivalents, receivables, and accounts payable and accrued expenses approximate fair value. The estimated fair value and carrying value of our outstanding debt instruments (excluding the carrying value of equity and mezzanine equity components of our convertible notes) were as follows:

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 $82 million in 2019. The fair values were based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment (Level 3). As of August 29, 2019, assets held for sale were not material.
