Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives | Derivatives As of June 30, 2023, we had an open position of 59,187 tonnes related to LME forward financial sales contracts to fix the forward LME aluminum price. These contracts are expected to settle monthly through December 2024. We have also entered into financial contracts with various counterparties to offset fixed price sales arrangements with certain of our customers ("fixed for floating swaps") to remain exposed to the LME and MWP aluminum prices. As of June 30, 2023, we had 2,961 tonnes related to fixed for floating swaps that will settle monthly through November 2023. We have entered into financial contracts to hedge a portion of Grundartangi's exposure to the Nord Pool power market (“Nord Pool power price swaps”). All of the Nord Pool power price swaps are expected to cash settle monthly through December 2023. The Nord Pool power price swaps are settled in Euros, therefore we have entered into financial contracts to hedge the risk of fluctuations associated with the Euro ("FX swaps"). As of June 30, 2023, we had an open position related to the FX swaps of €16.4 million that will settle monthly through December 2023. During the third quarter of 2022, we entered certain floating Nord Pool financial contracts to unwind a portion of our fixed contract position as a result of the recent power agreement amendment, making us predominantly hedged against Nord Pool power price fluctuations during 2023. As of June 30, 2023, we had an open net position of 499,116 MWh related to the Nord Pool power price swaps. We have entered into financial contracts to fix a portion of our exposure to the Indiana Hub power market at our Kentucky plants ("Indiana Hub power price swaps"). As of June 30, 2023, we had an open position of 88,320 MWh. The Indiana Hub power price swaps are expected to settle monthly through December 2023. We have entered into forward contracts to hedge the risk of fluctuations associated with the Icelandic Krona (ISK) and Euro for contracts related to the construction of the Grundartangi casthouse and the Sebree casthouse project denominated in these currencies ("casthouse currency hedges"). As of June 30, 2023, we had an open position related to the ISK casthouse swaps of kr24.0 million that will settle monthly through January 2024. As of June 30, 2023, we had an open position related to the Euro casthouse swaps of €4.9 that will settle monthly through January 2024. We have entered into financial contracts to hedge a portion of our exposure at our operations to the NYMEX Henry Hub (“NYMEX Henry Hub natural gas price swaps”). The natural gas volume is measured per million British Thermal Units ("MMBtu"). As of June 30, 2023, we had an open position of 600,000 MMBtu. The NYMEX Henry Hub natural gas price swaps are expected to settle monthly through October 2023. Our agreements with derivative counterparties contain certain provisions requiring collateral to be posted in the event the market value of our position exceeds the margin threshold limit of our master agreement with the counterparty.
