Paragraphs:
Other Income (Loss), Net The components of other income (loss), net, are summarized as follows (in millions):
The total change in net gains (losses) on available-for-sale debt investments was primarily attributable to lower realized losses as a result of market conditions, and the timing of sales of these investments.
The total change in net gains (losses) on marketable equity investments was attributable to market value fluctuations and the timing of recognition of gains and losses.
The change in net gains (losses) on non-marketable equity and other investments was primarily due to lower realized gains, partially offset by higher unrealized gains.
The change in other gains (losses), net was primarily driven by higher donation expense in the prior year.
