GAINS (LOSSES) ON EQUITY INVESTMENTS AND INTEREST AND OTHER, NET
GAINS (LOSSES) ON EQUITY INVESTMENTS, NET
Ongoing mark-to-market net gains and losses reported in 2019 and 2018 were primarily driven by ASML Holding N.V. (ASML) and Cloudera Inc. (Cloudera). During 2019 we sold our equity investment in ASML.
In 2019, we recognized $293 million in observable price adjustments primarily from one investment.
During 2018, we recognized an impairment charge of $290 million in our equity method investment in IMFT. During 2017, we recognized impairment charges in our investments of Cloudera for $278 million and Unisoc for $308 million.
Major drivers of sales of equity investments and other in 2019 were dividends of $632 million from McAfee and a gain of $107 million from our sale of our non-controlling interest in IMFT. In 2017, we recognized $3.4 billion in realized gains on sales of a portion of our interest in ASML.
INTEREST AND OTHER, NET
We recognized a higher net gain in interest and other in 2019 compared to 2018, primarily due to lower loss on debt conversions and larger divestiture gains in 2019 compared to 2018.
We recognized a net gain in interest and other in 2018 compared to a net loss in 2017, primarily due to lower losses on debt conversions, higher assets under construction resulting in more capitalized interest, and larger divestiture gains in 2018 compared to 2017.
Question:
What were the main reasons for a higher net gain in interest and other in 2019 compared to 2018?
Answer: Higher net gain in interest and other in 2019 compared to 2018, primarily due to lower loss on debt conversions and larger divestiture gains in 2019 compared to 2018.
