​ (1) During the third quarter of 2022, the Company signed an agreement for an option to potentially acquire a battery-grade lithium hydroxide monohydrate plant with a production capacity of approximately 20,000 tons per year from lithium sulfate salts. In addition, the transaction secures rights to adjacent land for future expansion. The acquisition cost totals CNY 869 million (ThUS$ 125,591) broken down into a deposit of CNY 204.5 million (ThUS$ 29,322) paid in the first quarter of 2023, CNY 57.5 million (ThUS$ 8,310) paid in the first quarter of 2023 and the remaining balance would be paid subject to the fulfillment of various conditions precedent in the second quarter of 2023. The Company´s payments would be backed by various guarantees granted by the seller and any failure to fulfil the conditions required by the contract would be considered a material breach of contract, giving the Company the right to demand the restitution of the amounts already paid.

​ Effectiveness The Company uses CCS, Forwards and IRS to hedge the potential financial risk associated with exchange rate and interest rate volatility. The objective is to hedge the exchange rate and inflation financial risks associated with bond obligations, exchange rate financial risks associated with investments in Chilean pesos, exchange rate financial risk associated with projects under construction in Australian dollars and interest rate financial risk associated with bank loans. Hedges are documented and qualitatively assessed to demonstrate their effectiveness based on a comparison of their critical terms. The hedges used by the Company as of the reporting date are highly effective given that the amounts, currencies, exchange dates and rates of the hedged item and the hedge are aligned, maintaining a close economic relationship. 12.4Financial liabilities Other current and non-current financial liabilities As of December 31, 2022 and 2021, the detail is as follows:

​ 12.7Fair value measurement of finance assets and liabilities The fair value hierarchy is detailed as follows:
| (a) | Level 1: The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and equity securities) is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the Company is the current bid price. These instruments are included in level 1.
| (b) | Level 2: The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.
| (c) | Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. This is the case for unlisted equity securities.
