## 0. Scope of this addendum

This addendum **does not modify** v1.0. The v1.0 framework — base date, base value, weighting equations, eligibility section, re-balancing schedule, all 16 originally registered family members — remains canonical, byte-stable, and Bitcoin-stamped.

This addendum **extends** the TS-GMRI family with one new registered methodology slot and formalises the concept of a **wrapper dimension** in the universe, alongside the existing dimensions of *filter* (which metals) and *weighting* (how they combine).

---

## 1. New concept: wrapper dimension

Up to v1.0, every TS-GMRI member shared the same wrapper type:

> **Wrapper = direct physical-metal claim.** A constituent token represents a fractional ownership interest in a specific quantity of physical metal held in a vault, refinery, or other physical custody, redeemable or backed 1:1 in audited form.

v1.1 introduces an explicit **wrapper field** on each family member. The wrapper field declares the *type of legal claim* the underlying constituent represents. Permitted values:

| Wrapper code | Meaning | Example constituents |
|---|---|---|
| `physical` | Direct claim on physical metal in vault | PAXG, XAUT, KAU, KAG, XAUM, XAGM, …  (the v1.0 universe) |
| `equity` | Tokenized share in a metal-producing company | Robinhood EU stock tokens (BHP, RIO, NEM, FCX), Dinari dShares (dFCX, dNEM), Backed Finance xStocks |
| `etf-wrap` | Tokenized share in an existing physical-metal ETF | Backed Finance bGLD (PAX Gold), tokenized GLD/SLV/GDX (where issued) |
| `royalty` | Tokenized share in a royalty/streaming company | Future tokenization of Wheaton, Franco-Nevada, Royal Gold, Triple Flag (none live as of 17 June 2026) |
| `derivative` | Tokenized swap, perp, or forward on metal | Excluded; methodology slot reserved for prior art only |

**Wrappers are not additive.** A reader may not sum TS-GMRI (physical wrapper) with TS-GMRI-PROD (equity wrapper) to derive a single "metals exposure" figure. The underlying economic claims are mathematically distinct (a kilogram of bullion ≠ a share of a mining company), and the risk decompositions differ materially.

All sixteen v1.0 family members are hereby tagged `wrapper = physical`. This tagging is a documentation refinement only; no value, weight, or eligibility rule changes.

---

## 2. New family member: TS-GMRI-PROD (slot, awaiting constituents)

| Field | Value |
|---|---|
| Code | `GMRI-PROD` |
| Display name | **TS-GMRI Metal Producers (Equity Wrapper)** |
| Wrapper | `equity` |
| Filter rule | `wrapper = equity AND issuer_business = metal_producer` |
| Weighting | Market-cap weighted with 25% single-issuer cap |
| Base date | 7 June 2026 (shared with rest of family) |
| Base value | 100 |
| Publication threshold | N ≥ 3 eligible constituents from ≥ 2 distinct tokenization issuers |
| Current N | 0 |
| Current value | Not published (below threshold) |
| Status | Methodology slot — pre-launch |

### 2.1 Eligibility

A constituent token is eligible for TS-GMRI-PROD if and only if **all** of the following are satisfied:

1. The underlying equity is listed on a recognised stock exchange in the LSE, NYSE, NASDAQ, HKEX, ASX, TSX, SGX, JPX, or SIX universe.
2. The issuing company's primary business (≥ 50% of revenue or ≥ 50% of identifiable assets) is metal extraction, processing, refining, recycling, or royalty/streaming of physical metals, as defined by GICS Materials sub-industries 1510101010 through 1510304030.
3. The tokenization wrapper is regulated by a tier-1 jurisdiction regulator: US SEC/FINRA broker-dealer, EU MiFID II investment firm, CH FINMA, HK SFC Type 1/4/7, or SG MAS CMS.
4. The token issuer has published the on-chain smart contract address(es) of the constituent token, and maintains a verifiable 1:1 backing audit performed at least monthly by a qualified independent auditor.
5. The constituent token has a 30-day rolling average daily on-chain trading volume of at least USD 50,000 across its primary venues, as measured by CoinGecko or equivalent aggregator.
6. The token issuer publishes regular share-backing attestation (monthly minimum).

A constituent that ceases to satisfy any of the above is removed at the next scheduled re-balance (monthly), with no retroactive adjustment to historical index values.

### 2.2 Weighting

TS-GMRI-PROD uses **market-cap weighted, issuer-capped at 25%**, with overflow redistributed pro-rata to uncapped issuers. The cap is set higher than the 20% used in TS-GMRI-CAP20 because the producer universe is expected to be smaller (N = 3 to 30) and the cap-redistribution effect therefore more material. The cap is reviewed annually at the calendar-year-end re-balance.

Market cap is computed as: token's on-chain circulating supply × the issuer's published share price at 23:59 UTC on the re-balance date. Where the issuer publishes the share-price in a currency other than USD, the WM/Reuters 16:00 London Fix on the same date is used for conversion.

### 2.3 Risk decomposition vs core TS-GMRI

A TS-GMRI-PROD constituent's price equals (approximately):

> producer equity value × tokenization wrapper basis

A TS-GMRI (core) constituent's price equals (approximately):

> reference metal price × redemption discount/premium

The TS-GMRI-PROD price therefore carries three additional risk dimensions that TS-GMRI does not:

1. **Operational leverage:** miner equity moves more than the underlying metal in both directions, by a factor approximately equal to (1 + debt/equity) × (1 − all-in-sustaining-cost / metal price).
2. **Management quality:** capex discipline, hedge book, jurisdiction allocation, dividend policy.
3. **Securities regulation:** the wrapper is a security in every tier-1 jurisdiction; the constituent token is subject to KYC/AML, suitability, and trading-venue restrictions that do not apply to physical-metal wrappers.

These risks are inherent to the equity asset class. The index does not attempt to hedge them; TS-GMRI-PROD is published as a *benchmark of the wrapper's natural performance*, not a synthetic pure-metal exposure.

### 2.4 Rationale for slot registration on 17 June 2026

As of the slot registration date, no operator has published a public benchmark dedicated to tokenized metal-producer equities. The natural analogs in conventional finance — GDX (VanEck Gold Miners), COPX (Copper Miners), SIL (Silver Miners), LIT (Lithium & Battery Tech), URA / URNM (Uranium), PICK (iShares Diversified Mining) — are each multi-billion-dollar products and have been live for 10–20 years. The tokenized equivalent is in early formation:

- **Robinhood EU stock tokens** (live since June 2025) include BHP, Rio Tinto, Newmont, Freeport-McMoRan, SQM, Albemarle.
- **Dinari dShares** offers dFCX, dNEM, dSQM and others to non-US investors.
- **Backed Finance xStocks** has confirmed the technical capability to add miner-equity wrappers; no dedicated launches as of 17 June 2026.
- **Swarm Markets** (BaFin-regulated) hosts tokenized equities including selected miners.

The publication threshold of N ≥ 3 from ≥ 2 distinct tokenization issuers is expected to be met within the 2026 H2 – 2027 H1 window. The slot is registered now to establish prior art for the methodology framework, in line with the v1.0 principle of *registering rules ahead of constituents* (the same approach used for TS-GMRI-BASE, -BTR, -FE, -LT, -MN, -REF, -STL, -CRT, -FA, and -JUR at v1.0 publication).

## 3. Family member count update

The TS-GMRI family now comprises **17 registered members**:

- 6 live: TS-GMRI, TS-GMRI-EW, TS-GMRI-CAP20, TS-GMRI-AU, TS-GMRI-PRE, TS-GMRI-NONAU.
- 11 methodology slots (pre-launch): TS-GMRI-BASE, TS-GMRI-BTR, TS-GMRI-FE, TS-GMRI-CRT, TS-GMRI-FA, TS-GMRI-LT, TS-GMRI-MN, TS-GMRI-REF, TS-GMRI-STL, **TS-GMRI-PROD (new in v1.1)**, TS-GMRI-JUR.

All other v1.0 specifications — eligibility (Section 3 of v1.0), data discipline, re-balancing schedule, governance, license, and the v1.0 base date and value — are preserved without amendment.
