Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Financial Instruments | Derivative Financial Instruments The Company utilizes derivative instruments to reduce its exposure to fluctuations in commodity prices and foreign exchange rates, under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company’s agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Derivatives in Cash Flow Hedging Relationships Lead Forward Contracts The Company enters into lead forward contracts to fix the price for a portion of its lead purchases. Management considers the lead forward contracts to be effective against changes in the cash flows of the underlying lead purchases. The vast majority of such contracts are for a period not extending beyond one year. At March 31, 2019 and 2018, the Company has hedged the price to purchase approximately 42.0 million pounds and 62.9 million pounds of lead, respectively, for a total purchase price of $39,218 and $72,207, respectively. Foreign Currency Forward Contracts The Company uses foreign currency forward contracts and options to hedge a portion of the Company’s foreign currency exposures for lead, as well as other foreign currency exposures so that gains and losses on these contracts offset changes in the underlying foreign currency denominated exposures. The vast majority of such contracts are for a period not extending beyond one year. As of March 31, 2019 and 2018, the notional amount of these contracts was $42,318 and $54,164, respectively. In the coming twelve months, the Company anticipates that $46 of pretax loss relating to lead and foreign currency forward contracts will be reclassified from AOCI as part of Cost of goods sold. This amount represents the current net unrealized impact of hedging lead and foreign exchange rates, which will change as market rates change in the future, and will ultimately be realized in the Consolidated Statements of Income as an offset to the corresponding actual changes in lead costs to be realized in connection with the variable lead cost and foreign exchange rates being hedged. Derivatives not Designated in Hedging Relationships Foreign Currency Forward Contracts The Company also enters into foreign currency forward contracts to economically hedge foreign currency fluctuations on intercompany loans and foreign currency denominated receivables and payables. These are not designated as hedging instruments and changes in fair value of these instruments are recorded directly in the Consolidated Statements of Income. As of March 31, 2019 and 2018, the notional amount of these contracts was $22,201 and $28,486, respectively. Presented below in tabular form is information on the location and amounts of derivative fair values in the Consolidated Balance Sheets and derivative gains and losses in the Consolidated Statements of Income: Fair Value of Derivative Instruments March 31, 2019 and 2018
