Facility and approval
POSCO Argentina obtained approval from IDB Invest on August 4 for a short-term credit facility of up to US$700 million to fund operations of its Argentine brine lithium business.
Use of proceeds and timeline
The approved facility will provide working capital for the subsidiary’s first and second brine lithium plants; the second plant is scheduled for completion in the second half of the year.
Financial terms and incentives
Under the intergovernmental agreement establishing the IDB, preferential tax treatment will apply to interest payments and financial transaction taxes incurred in the borrowing process, which is expected to reduce financing costs and enhance project profitability and competitiveness.
