(a)Valuation is based on unadjusted quoted prices in active markets for identical financial instruments. (b)Valuation is based on inputs that are observable for the financial instruments, which include quoted prices for similar instruments or identical instruments in markets which are not considered to be active, or inputs, either directly or indirectly based on observable market data. Valuation is based on inputs that cannot be observed using market data (unobservable inputs). The change in valuation of our level 3 instruments for the period to 30 June 2024 and 31 December 2023 is as follows:
| 30 June 2024 | 31 December 2023
Level 3 financial assets and liabilities | US$m | US$m
Opening balance | 147 |  | 131 |
Currency translation adjustments | (1) |  | (2) |
Total realised gains/(losses) included in: |  |
– consolidated sales revenue | — |  | 12 |
– net operating costs | (11) |  | (18) |
Total unrealised gains/(losses) included in: |  |
– net operating costs | 94 |  | 43 |
Total unrealised gains/(losses) transferred into other comprehensive income through cash flow hedges | 9 |  | (1) |
Additions to financial assets/(liabilities) | 50 |  | 29 |
Disposals/maturity of financial instruments | (16) |  | (47) |
Closing balance | 272 |  | 147 |
Net gains included in the income statement for assets and liabilities held at period end | 84 |  | 31 |
(d)Our Cash and cash equivalents of US$9,256 million (31 December 2023: US$9,673 million), includes US$4,129 million (31 December 2023: US$2,722 million) relating to money market funds which are treated as fair value through profit or loss (FVPL) under IFRS 9 with the fair value movements reported as finance income. (e)Investments in equity shares and funds include US$192 million (31 December 2023: US$157 million) of equity shares, not held for trading, where we have irrevocably elected to present fair value gains and losses on revaluation in other comprehensive income (FVOCI). The election is made at an individual investment level. (f)Other investments, including loans, covers cash deposits in rehabilitation funds, government bonds, managed investment funds and royalty receivables. (g)Trade receivables include provisionally priced invoices. The related revenue is initially based on forward market selling prices for the quotation periods stipulated in the contracts with changes between the provisional price and the final price recorded separately within “Other revenue”. The selling price can be measured reliably for the Group's products, as it operates in active and freely traded commodity markets. At 30 June 2024, US$1,080 million (31 December 2023: US$1,362 million) of provisionally priced receivables were recognised. (h)Level 3 derivatives mainly consist of derivatives embedded in electricity purchase contracts linked to the LME, midwest premium and billet premium with terms expiring between 2025 and 2036 (31 December 2023: 2025 and 2036). Derivatives related to renewable power purchase agreements are linked to forward electricity prices with terms expiring between 2053 and 2054. (i)Net debt derivatives include interest rate swaps and cross-currency swaps. As part of the International Swaps and Derivatives Association (ISDA) Fallbacks Protocol, on 1 July 2023 we completed the transition of our US LIBOR derivatives to SOFR on cessation of US LIBOR at 30 June 2023. There was no impact on our hedging arrangements after taking into account the IFRS 9 ‘Financial Instruments’ LIBOR reform reliefs. (j)Trade and other financial payables comprise trade payables, other financial payables, accruals and amounts due to equity accounted units. The techniques used to value our more significant fair value assets/(liabilities) categorised under level 2 and level 3 are summarised below:

The following table shows the carrying value and fair value of our borrowings including those which are not carried at an amount which approximates their fair value 30 June 2024 and 31 December 2023.
