Executive Implications — Balance Sheet
  • The $916.5M total asset base is anchored by the UNFC-basis COA Reserve ($621M) — the contractual feedstock stream's gross lifetime value. This is the primary lender collateral argument.
  • PP&E at $247.5M provides 1.54× tangible coverage of the $160.875M senior debt. Lenders hold both real assets and reserve collateral simultaneously.
  • Carbotura's contributed IP and COA rights ($669M) represent non-cash equity — the institutional partner's $49.5M cash equity is the minority funded stake at close; Carbotura holds the majority in contributed technology value.
  • The DSRA (Debt Service Reserve Account) — funded from debt proceeds — ensures Year 1 debt service is covered regardless of DSCR ramp. This is a lender requirement, not a structural weakness.

§3.3 — UNFC Urban Mining Framework

UNFC Classification — Proven Feedstock Reserve

1. UNFC Classification Statement. Nagpur Municipal Corporation's manufacturing feedstock stream is classified as a Proven Feedstock Reserve under the United Nations Framework Classification for Resources (UNFC) Urban Mining application. Proven Feedstock Reserve: 146,000 TPY (Phase Initial) · Counterparty: Nagpur Municipal Corporation · COA term: 30 years. UNFC axis classification: E1 (economically viable — confirmed TMC Fee schedule at $100/ton, escalating 2.5%/yr, under COA); F1 (technically feasible — commissioned ACM facility specification per MCR process design); G1 (supply confirmed — Circular Offtake Agreement with NMC as counterparty).

2. Two Legitimate Valuation Bases. The COA Reserve carries two valuation bases used by institutional lenders and equity investors:

  • UNFC-basis Gross LOM NRV — contracted feedstock volume × TMC unit value over COA term, undiscounted: $621.0M. This is the resource statement basis and primary lender collateral measure. Infrastructure lenders use reserve/debt coverage ≥5× as a floor; Nagpur Phase Initial achieves 3.86× on TMC stream only (supplemented by PP&E). Full revenue basis (TMC + RevCon products): ~$1,446M / $160.875M = 8.99×.
  • DCF NPV — discounted present value of COA cash flows at 8% discount rate: ~$200M (ESTIMATED). This is the economic equity value basis used for IRR and MOIC. The DCF NPV appears in §5 partner return analysis; the UNFC-basis Gross LOM NRV appears as the intangible asset on the IFRS opening balance sheet.

3. Circular Advantage — Perpetual Throughput. Unlike a geological mine, Nagpur's feedstock source does not deplete. The NMC waste stream is structurally growing at ~1.3% per annum and is contractually renewed under the 30-year COA. The COA Reserve does not amortise on a declining-production basis — it supports a Perpetual Growth model. Phase Initial Proven Feedstock Reserve: 146,000 TPY confirmed. "Throughput Reliability is contractually anchored by the 30-year Circular Offtake Agreement with Nagpur Municipal Corporation."

Assumption — TMC Fee

All return figures above use $100/ton TMC Fee (Carbotura standard floor). This is the floor — not the ceiling. The standard TMC range is $100–$150/ton. Nagpur's TMC is at floor because the estimated FWDC ($15/ton) is below the formula floor. Upside case: if Community Feasibility Study verifies a higher full-system FWDC, TMC Fee remains at $100/ton (floor is binding). Upside case for IRR comes from RevCon product revenue growth and royalty escalation — not TMC Fee increase.

§7.3 — Three Canonical Sentences

Gross cost displacement is quantified separately from Circular Royalty cash flow. Full net fiscal position reflects both.

At steady state, the Circular Royalty is designed to exceed the TMC Fee on a per-ton basis.

Circular Royalty payments begin 13 months after corresponding TMC Fee payments and ramp to full run-rate on a rolling basis.

Executive Implications — Circular Royalty Position
  • NMC's lifetime royalty receipt (~$628M) is 2.54× the lifetime TMC Fee obligation (~$247M). The COA is structured to be materially royalty-positive for NMC at all time horizons beyond Year 1.
  • The Circular Royalty grows faster than the TMC Fee in dollar terms because both rate (+1pp/yr) and base (+2.5%/yr) escalate simultaneously — creating compounding growth in the surplus.
  • At Year 30, NMC receives $297.58/ton in royalty against $206.10/ton in TMC Fee — a steady-state spread of +$91.48/ton on 146,000 TPY = +$13.36M/yr net, growing every subsequent year under any COA extension.
  • The 30-year COA Reserve underpins the SPV's asset base (UNFC-basis $621M) — the same revenue stream that generates NMC's royalty is the lender's primary collateral. The interests of NMC, lenders, and equity investors are structurally aligned.
