What is valued here is the series as a whole: the net asset value behind all units outstanding, and the value of one unit. A holder's position is their units multiplied by the unit value of the day. Per the PPM the unit is a contractual claim on the issuer, not ownership of copper.

Reading the attribution

NAV today − NAV yesterday = Cu + Ops + Hedge + HC + Fee (+ Flows)

Flows appear when units were issued or retired. Every figure comes from a dated event with a piece of evidence; nothing enters the valuation without one. The reference copper price is recorded daily as an input; the inventory is revalued only when the implied change exceeds the series' materiality threshold, and that revaluation is itself an event approved by a manager.

Cu
Copper price
Revaluation of the inventory because the market price of copper moved.
Source: Revaluation events with cause "price"; LME cash settlement on the valuation date.
FX
Currency
The euro the series holds between converting and paying, revalued at the day's reference rate, and the rate a euro payment was booked at.
Source: ECB euro reference rate; the rate of each euro payment from its confirmation.
Ops
Operational cycle
Costs incurred, quantity and quality changes, and the margin when the sale is priced.
Source: Cycle events submitted by the partners with evidence: invoices, assays, sale contract, bank confirmations.
Hedge
Hedge P&L
Change in the result of the temporary copper hedge since the previous mark.
Source: Broker statement, mark-to-market; margin posted is an asset and does not affect NAV.
HC
Haircut ladder
Money withheld while an asset is at risk, released as it moves towards cash: scrap paid 3.5 % → in custody 2.5 % → refined 1.5 % → receivable 0.5 % → cash 0.
Source: Computed by the engine from the asset class after each event; not an input.
Fee
Management fee
One day of the annual management fee, accrued on the NAV before fees.

How to verify

Each day links to a signed JSON attestation. The signature covers the canonical JSON of every field except signature (keys sorted, no whitespace), algorithm Ed25519.

The event log the valuation was computed from is published as events.json; its SHA-256 is inside every attestation, together with the per-event contributions shown in the hover cards.

The hash of each day — the SHA-256 of the canonical JSON of that day's attestation — is published in anchors.json and written on chain once, to a contract that lets no day be written twice with a different value. Where the anchor column links to a transaction, that transaction carries the hash beside it here; recompute it from the attestation and compare.

The attestation itself carries no anchor: it is the document that was hashed, so a transaction hash written into it would change what was anchored.
