THE PLUMBING · Post 7 · All Six. One Deal. Everything Legal.
① Charitable Deduction
② Stepped-Up Basis + 1031
③ Carried Interest
④ Delaware LLC
⑤ Check-the-Box
⑥ Cayman Islands
The Complete Stack
One Transaction. $100 Million in Arizona Groundwater. Six Mechanisms Running Simultaneously. Every Layer Documented in Public Records, Regulatory Filings, and Primary Sources. The Beneficial Owners: Invisible. The Tax Advantage: Substantial. The Mechanism: Entirely Legal. This Is What the Plumbing Looks Like When All the Pipes Are Open at Once. The Great Estate — the Medieval Institution That Stacked Every Available Protection — Has a Modern Address in Wilmington, Delaware, and a Fund Vehicle in the Cayman Islands. The Water Is in Arizona. Nobody in La Paz County Can Find Out Who Owns It.
Every mechanism documented in this series has been examined individually. The charitable deduction and its 1601 ancestor. The 1921 Revenue Act that created stepped-up basis and the 1031 exchange in a single legislative moment. The carried interest that migrated from Texas oil fields to New York PE firms. The Delaware LLC that makes beneficial owners invisible. The Check-the-Box regulation that makes offshore subsidiaries disappear. The Cayman Islands that has provided zero-tax asset holding since 1966. Six posts. Six pipes. In practice, they do not operate individually. They operate as a stack — simultaneously, on the same transaction, each layer making the others more powerful. This post assembles them in one place. The transaction: the $100 million acquisition of McMullen Valley groundwater in La Paz County, Arizona, in July 2024, documented in Series 5, Post 7. The buyer of record: Emporia III LLC. The fund: Water Asset Management. The mechanism: six layers deep, each one legal, each one documented, each one ancient in its structural logic, each one installed in American law at a specific moment by specific people with specific interests — and all of them, together, producing the same outcome they have always produced: the wealth that flows through the stack pays less than the wealth that doesn't. And the community that supplies the resource that makes the wealth possible cannot find out who owns the entity that controls it. The great estate is fully assembled. The stack is complete. Here is how it works.
The Medieval Precedent: The Great Estate
At the height of the feudal era, the most powerful lords did not rely on a single protection mechanism. They stacked them. Every available instrument — church patronage, entailed inheritance, feudal rent, merchant republic incorporation, straw man ownership, offshore trading posts — was deployed simultaneously. The great estate was the sum of all available protections operating at once.
The Great Estate — Medieval England, 1300s–1500s
Six Protections — One Lord
→Church patronage: Endow a chantry or monastery. The donated lands become charitable property — exempt from the feudal obligations that apply to secular landholdings. The lord's "generosity" reduces his taxable estate.
→Entailed inheritance: Land locked to pass intact to the eldest son across generations. Accumulated gains at each transfer: not triggered. The estate passes. The obligation doesn't.
→Feudal rent: The lord takes 20–30% of tenant production. His contribution: the land and the framework. His tax rate on this income: preferential — he is assessed on the land's value, not his share of its output.
→Feoffee to uses: Transfer legal title to a trusted nominee. The lord retains all practical benefit. The feudal obligations that attach to legal ownership: transferred away. The lord pays nothing on the transfer.
→Merchant republic incorporation: Register with Venice or Genoa as a trading partner. Assets held through merchant republic structures receive the legal protections and reduced obligations those jurisdictions offer.
→Offshore entrepot: Book trading profits through Rhodes or Malta — jurisdictions beyond the reach of the feudal tax collectors in the lord's home territory. The profits exist. The obligation does not attach.
The Complete Stack — Arizona, 2024
Six Mechanisms — One Fund
→Charitable deduction (Post 1): University endowments invest as LPs in the fund. Their contribution is subsidized by the charitable deduction. The endowment's tax-exempt status combines with the fund's offshore structure for compounded advantage.
→1031 exchange + stepped-up basis (Post 2): The exit from the Arizona position can be rolled into the next water rights acquisition via 1031 — deferring the gain. At the death of any individual beneficial owner, their interest steps up — the gain accumulated during their holding period disappears.
→Carried interest (Post 3): The fund managers receive 20% of profits above the hurdle rate. Their share is taxed at 20% capital gains rate — not 37% ordinary income. The wildcatter's gift, applied to water rights.
→Delaware LLC (Post 4): Emporia III LLC — the buyer of record in La Paz County. No beneficial ownership disclosure required. The 17,000 residents cannot find out who owns the entity that controls their aquifer.
→Check-the-Box (Post 5): Any offshore subsidiaries in the fund structure — holding companies, royalty vehicles, intercompany entities — may elect disregarded status, making their income invisible to the U.S. tax base until repatriation.
→Cayman Islands (Post 6): The fund vehicle itself — the limited partnership that pools institutional investor capital — is domiciled in the Cayman Islands. Zero corporate tax on fund-level returns. Distributions to LPs flow through without withholding.
The Stack — Layer by Layer
The Complete Stack — McMullen Valley Groundwater Acquisition, July 2024
Six mechanisms · All legal · All documented in public record and regulatory filings · All ancient in structural logic
①
Post 1 — Charitable Deduction · The Oldest Pipe (1601 → 1917 → 2026)
The Institutional Investors Are, In Part, Tax-Exempt Endowments
University endowments — Harvard, Yale, MIT, and others — are among the largest limited partners in PE funds globally. When an endowment like Harvard's $53 billion fund invests in a Water Asset Management vehicle, it does so as a tax-exempt institution. The contributions that built the endowment were deducted by donors at their marginal rate — up to 37 cents of public subsidy per dollar given. The endowment's returns compound tax-free. Its LP interest in the Cayman fund generates returns without triggering UBTI (with proper fund structuring). The oldest pipe — Elizabeth I's 1601 charitable trust framework — is the entry point of the capital stack.
Tax treatment: Endowment returns compound tax-free. Entry capital subsidized by charitable deduction.
⑥
Post 6 — Cayman Islands · The Island (1966 → 2026)
The Fund Vehicle Is a Cayman Limited Partnership
Water Asset Management structures its fund as a Cayman Islands limited partnership — the standard vehicle for institutional PE and hedge funds. The limited partners (university endowments, pension funds, sovereign wealth funds, high-net-worth individuals) hold LP interests in the Cayman vehicle. The Cayman LP itself pays zero corporate income tax on fund returns. Distributions to LPs flow without Cayman withholding. The fund-level returns are maximized before they reach investors who then apply their own tax treatment (tax-exempt for endowments, ordinary income or capital gains for taxable investors depending on character). The island provides the zero-tax aggregation layer.
Tax treatment: Zero corporate tax at fund level. $92M in assets per Cayman resident. Zero withholding on distributions.
④
Post 4 — Delaware LLC · The Race to the Bottom (1899 → 2024)
The Buyer of Record Is Emporia III LLC — Delaware Entity, No Disclosed Owners
The entity that appears in La Paz County Assessor records as the purchaser of 12,793 acres of McMullen Valley groundwater for $100 million is Emporia III LLC — a Delaware limited liability company. Delaware requires no public disclosure of LLC membership, management, or beneficial ownership. The public record available to La Paz County residents contains the entity name, purchase price, and acreage. Nothing else. The 17,000 people whose aquifer is now held by this entity cannot determine from any public record who the beneficial owners are, which institutional investors provided the capital, or who will make the decisions about whether and when the water is transferred to Phoenix suburbs. The Delaware LLC is the anonymity layer that sits between the public-facing transaction and the private ownership structure.
Disclosure treatment: Beneficial ownership — NOT IN THE PUBLIC RECORD. Available to law enforcement with process. Not available to affected community.
③
Post 3 — Carried Interest · The Wildcatter's Gift (1954 → 2026)
The Fund Managers Collect 20% of Profits at 20% Tax Rate
Water Asset Management's general partners — the fund managers who identified the McMullen Valley opportunity, structured the acquisition, negotiated the purchase, and will manage the position toward its eventual transfer — receive a carried interest of typically 20% of fund profits above the hurdle rate. This carry is taxed as long-term capital gains (20% + 3.8% NIIT = 23.8%) rather than ordinary income (37% + 3.8% = 40.8%). The 17-percentage-point differential on a $100 million position with a projected 2–3× return represents tens of millions of dollars taxed at a preferential rate. The wildcatter's 1954 logic — expertise-based profit participation deserves capital gains treatment — applies to water rights acquisition in 2024 with the same force it applied to oil field operations seventy years ago. Congress has tried to close this since 2007. The rate: 20%. Unchanged since Eisenhower.
Tax treatment: Carry taxed at 20% (not 37%). On projected returns: tens of millions in preferential treatment. Rate unchanged since 1954.

Post 5 — Check-the-Box · The Invisible Subsidiary (1996 → 2026)
Offshore Holding Entities in the Structure May Be Elected Into Nonexistence
Complex PE fund structures typically include multiple entity layers for legal, tax, and operational reasons — holding companies, blocker corporations, royalty vehicles, management entities. Where any of these are organized in jurisdictions outside the United States, they may elect disregarded entity status under the Check-the-Box regulations. A holding company in the Cayman Islands that aggregates fund returns before distributing to the Cayman LP can be checked into nonexistence for U.S. tax purposes — its income invisible to the U.S. tax base until the repatriation decision is made. The regulation that Treasury issued in 1996 without a congressional vote, that the Joint Committee on Taxation identified as one of the largest unintended revenue losses in modern tax history, is the layer that makes offshore holding income disappear from U.S. taxation during the holding period.
Tax treatment: Offshore holding entity income: not currently taxable in U.S. GILTI applies to certain categories. Deferral during holding period: available.

Post 2 — 1031 Exchange + Stepped-Up Basis · The 1921 Room (1921 → 2026)
The Exit Is a 1031 Roll Into the Next Position. The Heirs Inherit at Stepped-Up Basis.
When Water Asset Management's position in McMullen Valley is eventually sold — to a Phoenix suburb, a municipal water authority, or another buyer — the gain on the $100 million acquisition will be substantial. If the sale proceeds are rolled into another qualifying real property position via a 1031 exchange, the gain is deferred. Not eliminated — deferred. It travels forward into the next water rights position, and the next, and the next. If any individual beneficial owner of the fund dies while holding their interest, their interest steps up in basis at death — the gain accumulated during their holding period disappears. The mechanisms the Revenue Act of 1921 created in the same legislative moment — the entailed estate and the manor swap, modernized — are the exit layer of the stack. The gain that enters the stack: may never be taxed in full.
Tax treatment: 1031 roll defers gain indefinitely. Stepped-up basis at death eliminates gain permanently. Combined: Buy, Borrow, Die on water rights.
The Chain of Ownership — What the Public Record Shows
From Institutional Investor to Arizona Groundwater — The Documented Chain
Layer 1 — Entry Capital
University Endowments, Pension Funds, Sovereign Wealth Funds
Tax-exempt or low-tax institutional investors. Capital contributed subsidized by charitable deduction (endowments). Identity: disclosed to fund manager, not to public.
→
Layer 2 — Fund Vehicle
Cayman Islands Limited Partnership
Water Asset Management fund. Zero corporate tax. Zero withholding. Beneficial ownership: not in public record. Managers: WAM GP entity (Delaware or similar).
→
Layer 3 — Acquisition Entity
Emporia III LLC (Delaware)
Buyer of record in La Paz County. No disclosure of members or managers required. Public record: entity name, price, acreage. Beneficial owners: NOT IN THE PUBLIC RECORD.
→
Layer 4 — The Asset
12,793 Acres, McMullen Valley, La Paz County, Arizona
Groundwater rights attached. 17,000 county residents. Aquifer being positioned for eventual transfer to Phoenix suburbs. Arizona legislators already drafting enabling legislation.
🔥 The Complete Smoking Gun
The Wealth That Flows Through the Stack Pays Less Than the Wealth That Doesn't. Every Time. By Design. Across 425 Years. On Groundwater in Arizona in 2024 As Surely As on Farmland in England in 1400.
This is the finding of seven posts and six mechanisms, assembled in one place.
The institutional investor who contributes capital to the fund: tax-exempt endowment, whose contributions were subsidized by charitable deductions at 37 cents per dollar. Entry cost to the stack: subsidized by the public.
The fund structure that pools the capital: Cayman Islands limited partnership, zero corporate tax, zero withholding on distributions. Aggregation cost: zero at fund level.
The acquisition entity that holds the asset: Delaware LLC, no beneficial ownership disclosure. Accountability cost: none. The affected community cannot find out who owns the entity that controls their water.
The fund managers who collect their share: 20% carried interest taxed at 20% rather than 37%. On projected returns from a $100M position: tens of millions of dollars taxed at the wildcatter's preferential rate. The wildcat's gift, applied to Arizona groundwater in 2024.
The offshore holding entities in the fund structure: checked into nonexistence under the 1996 Treasury regulation nobody voted on. Income during the holding period: invisible to U.S. taxation.
The exit from the position: 1031 exchange into the next water rights acquisition, deferring the gain indefinitely. Any gain that remains at an individual owner's death: stepped up, the accumulated appreciation erased. The 1921 Room's two mechanisms — the entailed estate and the manor swap — handling the terminal end of the chain.
What the La Paz County resident pays when the aquifer is eventually sold to a Phoenix suburb: market prices for water in a basin made scarce by the 1922 Compact's over-allocation — the same over-allocation that excluded the Navajo Nation from the room where the river was divided.
The wealth that flows through the complete stack pays less than the wealth that doesn't. At every layer. The entry is subsidized. The aggregation is tax-free. The anonymity is structurally guaranteed. The managers' share is preferentially taxed. The holding income is deferred. The exit is rolled forward. The death is a step-up. The community that supplies the resource pays full price. The structure that extracts the resource pays less than full price at every point in the chain. This is what the plumbing looks like when all the pipes are open at once. This is what 425 years of accretion produces. This is the answer to "how is this legal?" It was designed to be. Not all at once. Not by one person. By every generation that added one more pipe — because they could, because it was legal, and because the returns funded the defense of what they'd built.

"The great estate is fully assembled. Every protection available in 425 years of Anglo-American wealth-preservation law is operating simultaneously on this transaction. The community that supplies the resource pays full price. The structure that extracts the value pays less at every layer. The water is in Arizona. The wealth is in the Cayman Islands. The beneficial owners are in Delaware. Nobody can see through any of those walls."
— The complete stack, July 2024 — La Paz County, Arizona
The Finding — Post 7
"Seven posts to assemble six mechanisms. One transaction to show them all operating at once. The entailed estate and the manor swap. The lord's share of the harvest. The merchant republic of Wilmington. The feoffee to uses, updated by Treasury regulation in 1996. The offshore entrepot of George Town, Cayman Islands. The charitable trust framework of Elizabeth I's 1601 statute. All of them, on 12,793 acres of Arizona groundwater, purchased for $100 million through a Delaware LLC by a Cayman fund managed by a New York hedge fund whose beneficial investors cannot be identified from the public record. All legal. All documented. All ancient. All operating."
Final post: Post 8 — July 4, 2025. The One Big Beautiful Bill. The Magna Carta moment of the modern plumbing system: the permanent codification of mechanisms that had been accreting since 1601. Estate exemption raised to $15M per person — no sunset. Carried interest: intact. 1031 exchange: intact. Corporate rate permanent at 21%. The barons got their charter in 1215. The plumbing got its charter on Independence Day, 2025. The pipes were soldered shut. On the Fourth of July. The last post.
