OTHER INCOME (EXPENSE), NET
The components of other income (expense), net were as follows:
We use derivative instruments to: manage risks related to foreign currencies, equity prices, interest rates, and credit; enhance investment returns; and facilitate portfolio diversification. Gains and losses from changes in fair values of derivatives that are not designated as hedging instruments are primarily recognized in other income (expense), net.

Interest expense decreased primarily driven by a decrease in outstanding long-term debt due to debt maturities, offset in part by higher finance lease expense. Net recognized gains on investments decreased primarily due to lower gains on sales of equity investments. Net gains on derivatives includes gains on foreign exchange and interest rate derivatives in the current period as compared to losses in the prior period.
