We determined the fair value of the 2024 Term Loan Facility, the 2024-B Term Loan Facility, the Senior Notes due 2029 and the Senior Secured Notes due 2030 using quoted market prices, which under the fair value hierarchy is a Level 1 input. We determined the fair value of the RMB Term Loan Facility utilizing transactions in the listed markets for similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan and MGT Loan is based on the contracted amount which is a Level 2 input.
We determined the fair value of the foreign currency contracts, natural gas hedges, and the interest rate swaps using inputs other than quoted prices in active markets that are observable either directly or indirectly. The fair value hierarchy for the foreign currency contracts, natural gas hedges, and interest rate swaps is a Level 2 input.
The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term nature of these items.
