We manage exposure to changes in market interest rates. Our use of derivative instruments is limited to highly effective interest rate swaps to hedge the risk of changes in cash flows (future interest payments) attributable to changes in LIBOR swap rates, the designated benchmark interest rate being hedged on certain of our LIBOR indexed variable rate debt and a variable rate operating lease. The interest rate swaps effectively fix our interest payments on certain LIBOR indexed variable rate debt. We monitor our positions and the credit ratings of our counterparties and do not currently anticipate non-performance by the counterparties. Interest rate swap agreements are not entered into for trading purposes. The following is a summary of our interest rate swap agreements as of June 30, 2018:

Gains or losses recognized in income on derivatives are recorded as interest expense in the statements of operations. During the first quarter of fiscal 2019, we recognized an increase in the fair value of our cash flow hedges of $0.4 million, net of taxes. Embedded in this change was $0.5 million of losses reclassified from accumulated other comprehensive income (loss) to interest expense during the first quarter of fiscal 2019. As of June 30, 2018, we expect to reclassify $18 thousand of net gains on interest rate contracts from accumulated other comprehensive income (loss) to earnings as interest expense over the next twelve months.
