INDEPENDENT VERDICT
Moorstone Structured Commodities Master Fund II, L.P. is a useful example of why a Form D number cannot be read without understanding the legal structure behind it. The September 14, 2026 amendment reports a fully subscribed $1 billion Rule 506(b) offering, 63 investors and $0 remaining, but the filing expressly says that the $1 billion figure represents amounts sold by the master fund and its feeder fund together, including capital from applicable general partners and affiliates. That language matters because Moorstone Structured Commodities Offshore Fund II, LP filed its own amendment the same day and also reports $1 billion sold; those two filings do not evidence $2 billion of separate Fund II fundraising. They describe the same master/feeder capital pool from different legal entities. The March 17 filing had shown $626.05 million sold, so the September amendment reflects roughly $373.95 million of additional aggregate commitments between those dates. The current record therefore shows a fund that moved from a partially subscribed structure in March to a fully subscribed $1 billion structure by September, not two parallel billion-dollar funds.
THE MORE IMPORTANT STORY IS THE ANCHORAGE-TO-MOORSTONE TRANSITION
Fund II is also unusual because the investment platform itself changed identity during the fundraising cycle. Moorstone's official website states that Moorstone, L.P. is the former commodities business of Anchorage Capital Advisors, L.P., and outside transaction counsel Sterlington publicly described the business as the former Anchorage Structured Commodities Advisor operation transitioning into an independent adviser under Jason Siegel. Siegel, now Moorstone's Managing Partner, previously served as a Partner and Global Head of Commodities at Anchorage and had built Anchorage's dedicated structured-commodity investment effort. Timothy Schmidt, who signed the latest Fund II Form D as Chief Operating Officer, also came directly from the Anchorage commodities business. This is not a case where a new 2026 fund happens to share employees with an older manager: the investment team, strategy and operating infrastructure were deliberately carried out of Anchorage into a newly independent Moorstone platform.
THE SEC ADVISER RECORD EXPLAINS WHY MOORSTONE LOOKS NEW AND OLD AT THE SAME TIME
Moorstone, L.P. became an SEC-registered investment adviser effective January 2, 2026 under CRD 339519 and SEC number 801-134953. That registration date is recent, but the investment operation behind it predates the legal launch because the commodities team migrated from Anchorage. Current adviser-derived data reports approximately $2.18 billion of regulatory AUM and roughly $2.1 billion of private-fund gross assets across three funds, including approximately $570.8 million of gross assets in Moorstone Structured Commodities Master Fund II at the relevant Form ADV reporting point. That figure should not be confused with the later $1 billion Form D amount: Form ADV gross asset value is a balance-sheet-style fund measurement at a specific reporting date, while Form D "amount sold" measures securities sold in the offering. The two numbers answer different questions and can differ materially without either being wrong.
THE MASTER/FEEDER DESIGN IS CENTRAL TO HOW INVESTORS SHOULD READ THE FILINGS
The master vehicle is a Delaware limited partnership relying on Section 3(c)(7), while the offshore feeder is a Cayman Islands limited partnership using the same New York operating address, the same Moorstone investment manager and the same Fund II GP. The master filing reports 63 investors; the offshore feeder reports 31. Those counts should not simply be added without reviewing the subscription and ownership structure because some investor relationships may be represented through feeder entities rather than directly at master level. The offshore filing itself says its reported amount sold reflects the total amount sold by both the feeder and corresponding master directly. This explicit disclosure is one of the most important pieces of evidence in the case because it prevents a common research error: treating each Form D entity as an economically separate fundraising pool. Fund II should instead be understood as one structured-commodities strategy delivered through multiple legal sleeves.
MOORSTONE'S OPERATING INFRASTRUCTURE IS ALSO MORE VISIBLE THAN A TYPICAL NEW MANAGER
Northern Trust announced in March 2026 that Moorstone selected Northern Trust Hedge Fund Services for middle-office services, treasury and collateral management, fund administration, and financial and regulatory reporting through its Omnium platform. Adviser-derived records also identify Ernst & Young as auditor and Northern Trust as administrator and custodian for the broader private-fund platform. Those relationships are relevant because Moorstone's strategy is not a simple long-only commodities fund. The firm describes itself as providing opportunistic investments and flexible financing solutions across the global commodity supply chain, working with producers, consumers, intermediaries, asset owners, operators and financial institutions. Its team backgrounds span structured commodities finance, physical assets, distressed and special-situations credit, hedging and complex transaction structuring. For Fund II, the key investment risk is therefore not merely commodity-price volatility; investors need to understand counterparty exposure, collateral, physical-asset risk, financing terms, hedging, concentration by commodity and how bespoke structured transactions are valued.
FINAL ASSESSMENT
Moorstone Structured Commodities Master Fund II has a far richer diligence story than its $1 billion Form D headline suggests. The fund went from $626.05 million sold in March to a fully subscribed $1 billion by September; its offshore feeder reports the same aggregate capital pool rather than a second billion dollars; the investment manager became a standalone SEC-registered adviser only in January 2026 even though the team and strategy were inherited directly from Anchorage Capital Advisors; and the operating platform now has identifiable administration, custody and audit infrastructure. Those five facts together make Fund II difficult to confuse with a generic commodity fund. The remaining diligence questions are strategy-specific: how much of the portfolio consists of direct commodity exposure versus structured credit, how much capital is tied to physical assets or counterparties, what leverage and hedging are used, and how performance since the Anchorage transition compares with the earlier dedicated commodity funds managed by the same team.

IMPORTANT FORM D NOTICE
The $1 billion shown in the September 2026 Master Fund II Form D/A represents aggregate securities sold across the master/feeder structure as described by the issuer itself. The offshore feeder's separate $1 billion Form D figure should therefore not be added to the master figure as if it were a second independent billion-dollar raise. Moorstone's SEC adviser registration, CRD number and Form D filings confirm regulatory records; they are not SEC approval of the strategy, portfolio valuation or investment performance.
