Derivative Financial Instruments

We use certain interest rate derivative contracts to hedge interest rate exposures on our variable rate debt. We enter into foreign currency derivative contracts with financial institutions to reduce the risk that cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations. Our hedging program is not designated for trading or speculative purposes.

We recognize derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value. We record changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as cash flow hedges in our consolidated balance sheets as accumulated other comprehensive income (loss), and in our consolidated statements of income for those derivatives designated as fair value hedges.

In fiscal 2013, we entered into three interest rate swap agreements that we designated as cash flow hedges to fix the variable interest rates on a portion of borrowings under our term loan facility. In the first quarter of fiscal 2014, we entered into two interest rate swap agreements that we designated as cash flow hedges to fix the variable interest rates on the borrowings under our term loan facility. All of these interest rate swap agreements expired in May 2018. In the fourth quarter of fiscal 2018, we entered into five interest rate swap agreements that we designated as cash flow hedges to fix the variable interest rates on the borrowings under our Amended Term Loan Facility. The interest rate swaps expire in July 2023. At September 30, 2018 and October 1, 2017, the effective portion of our interest rate swap agreements designated as cash flow hedges before tax effect was $(1.3) million and $(0.05) million, respectively, all of which we expect to be reclassified from accumulated other comprehensive income (loss) to interest expense within the next 12 months.

As of September 30, 2018, the notional principal, fixed rates and related expiration dates of our outstanding interest rate swap agreements are as follows:



Notional Amount (in thousands)	Fixed Rate	Expiration Date
$50,000	2.79%	July 2023
50,000	2.79%	July 2023
50,000	2.79%	July 2023
50,000	2.79%	July 2023
50,000	2.79%	July 2023

The fair values of our outstanding derivatives designated as hedging instruments were as follows:



		Fair Value of Derivative Instruments as of
	Balance Sheet Location	September 30, 2018		October 1, 2017
		(in thousands)
Interest rate swap agreements	Other current assets	$	1,244	$	49

The impact of the effective portions of derivative instruments in cash flow hedging relationships and fair value relationships on income and other comprehensive income was immaterial for the fiscal years ended September 30, 2018 and October 1, 2017. Additionally, there were no ineffective portions of derivative instruments. Accordingly, no amounts were excluded from effectiveness testing for our interest rate swap agreements. We had no other derivative instruments that were not designated as hedging instruments for fiscal 2018, 2017 and 2016.
