The amortization of deferred debt issuance costs for the ABL Credit Facility and its predecessor is included in interest expense, and was $0.3 million, $0.3 million and $0.3 million for fiscal 2019, fiscal 2018 and fiscal 2017, respectively.

Accrued warranty

The following table summarizes the activity in Ciena’s accrued warranty for the fiscal years indicated (in thousands):



Year ended	Beginning		Current Year				Ending
October 31,	Balance		Provisions ⁽¹⁾		Settlements		Balance
2017	$	52,324	$	7,965	$	17,833	$	42,456
2018	$	42,456	$	20,992	$	18,708	$	44,740
2019	$	44,740	$	23,105	$	19,347	$	48,498

⁽¹⁾As a result of actual failure rates lower than expected, Ciena adjusted its fiscal 2017 provisions for warranty. These adjustments for previous fiscal year provisions had the effect of reducing warranty provisions by $9.7 million for fiscal 2017. During fiscal 2018 and fiscal 2019, Ciena determined that failure rates for prior estimates remained unchanged, and accordingly did not make any adjustments for previous fiscal year provisions not yet settled. As a result, Ciena’s warranty provision for fiscal 2018 and fiscal 2019 increased as compared to fiscal 2017.
