Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments | Fair Value of Financial Instruments: In assessing the fair value of financial instruments, we use methods and assumptions that are based on market conditions and other risk factors existing at the time of assessment. Fair value information for our financial instruments is as follows: Long-Term Debt—the fair values of our notes are estimated using Level 1 inputs and account for the difference between the recorded amount and fair value of our long-term debt. The carrying value of our remaining long-term debt reported in the accompanying consolidated balance sheets approximates fair value as substantially all of such debt bears interest based on prevailing variable market rates currently available in the countries in which we have borrowings.

Foreign Currency Forward Contracts—In the fourth quarter of 2019, we entered into a foreign currency forward contract, with a notional value of 727.9 million Australian Dollars, to hedge the cash flow exposure of non-functional currency purchases during the construction of the Kemerton plant in Australia. This derivative financial instrument is used to manage risk and is not used for trading or other speculative purposes. This foreign currency forward contract has been designated as a hedging instrument under ASC 815, Derivatives and Hedging. At December 31, 2020 and 2019, we had outstanding designated foreign currency forward contracts with notional values totaling the equivalent of $75.4 million and $481.2 million, respectively. We also enter into foreign currency forward contracts in connection with our risk management strategies that have not been designated as hedging instruments under ASC 815, Derivatives and Hedging, in an attempt to minimize the financial impact of changes in foreign currency exchange rates. These derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. The fair values of our non-designated foreign currency forward contracts are estimated based on current settlement values. At December 31, 2020 and 2019, we had outstanding non-designated foreign currency forward contracts with notional values totaling $611.1 million and $1.15 billion, respectively, hedging our exposure to various currencies including the Euro, Chinese Renminbi, Chilean Peso and Australian Dollar. The following table summarizes the fair value of our foreign currency forward contracts included in the consolidated balance sheets as of December 31, 2020 and 2019 (in thousands):

Total | $ | 13,606 |  |  | $ | 7,401 |  |  | $ | 4,803 |  |  | $ | 3,613 |
(a) Included $6.2 million in Other current assets and $0.9 million in Other assets at December 31, 2020 and $3.7 million in Other current assets and $1.7 million in Other assets at December 31, 2019. (b) Included $6.6 million in Other current assets and $4.8 million in Accrued expenses at December 31, 2020 and $2.0 million in Other current assets and $3.6 million in Accrued expenses at December 31, 2019. The following table summarizes the net gains (losses) recognized for our foreign currency forward contracts during the years ended December 31, 2020, 2019 and 2018 (in thousands):
| Year Ended December 31,
| 2020 |  | 2019 |  | 2018
Designated as hedging instruments: |  |  |  |  |
Gain recognized in Other comprehensive income (loss) | $ | 1,602 |  |  | $ | 4,847 |  |  | $ | — |
Not designated as hedging instruments: |  |  |  |  |
Losses recognized in Other expenses, net(a) | $ | (7,665) |  |  | $ | (25,765) |  |  | $ | (19,851) |
(a)Fluctuations in the value of our foreign currency forward contracts not designated as hedging instruments are generally expected to be offset by changes in the value of the underlying exposures being hedged, which are also reported in Other expenses, net. In addition, for the years ended December 31, 2020, 2019 and 2018, we recorded net cash settlements of $19.4 million, $23.6 million and $25.2 million, respectively, primarily within Changes in current assets and liabilities, in our consolidated statements of cash flows. As of December 31, 2020, there are no unrealized gains or losses related to the cash flow hedge expected to be reclassified to earnings in the next twelve months. The counterparties to our foreign currency forward contracts are major financial institutions with which we generally have other financial relationships. We are exposed to credit loss in the event of nonperformance by these counterparties. However, we do not anticipate nonperformance by the counterparties.
