Executive Summary

Suriname now has two separate ring-fence questions, and they must not be confused. The first is contractual: the Production Sharing Contract confines petroleum operations, cost recovery, accounting, profit-oil allocation and audit to a defined Contract Area and, within it, requires expenditure attribution to specific commercial fields. The second is statutory: the income-tax system must decide whether a taxpayer may use losses, financing charges or other deductions generated outside a profitable petroleum project to reduce the taxable income generated by that project. The PSC can solve the first question perfectly and still leave the second question unresolved.

The Suriname PSC architecture developed and refined during the 2008–2010 period is strong because it treats the Contract Area as an economic and accounting system. Petroleum expenditures are recoverable only from petroleum produced from that Contract Area; unrecovered expenditure remains the contractor’s risk; field costs must be separately identified; shared costs require an allocation method; affiliate charges are auditable; and each contractor party remains separately liable for income tax. These are not cosmetic drafting points. Together they protect the production-sharing equation from contamination by costs that do not belong to the contract.

The remaining vulnerability lies outside the PSC. If the corporate income-tax law permits a contractor or related Suriname taxpayer to offset GranMorgu taxable income with losses from another block, another project or an inadequately controlled financing structure, Suriname can lose or materially defer corporate income tax even though the PSC cost-recovery ring remains intact. The leak occurs in the tax return, not in the cost-oil account.

This paper therefore recommends a statutory petroleum fiscal ring fence, enacted before GranMorgu reaches first oil. The preferred boundary is each petroleum agreement or contract area, with tightly drafted rules for common infrastructure, pre-licence exploration, genuine shared services, decommissioning, reorganisations and change of ownership. The fiscal ring should be accompanied by project accounts, loss registers, interest-limitation rules, transfer-pricing documentation, beneficial-ownership disclosure, advance pricing capability and joint audit protocols between the tax authority and the petroleum regulator.

A transparent stylised GranMorgu model shows the scale of exposure. At a 36% corporate income-tax rate, every US$100 million of additional deductible losses transferred into the GranMorgu tax base reduces nominal tax by US$36 million. Under illustrative cross-block loss pools of US$0.75 billion, US$1.50 billion and US$3.00 billion, the nominal corporate-income-tax exposure is approximately US$270 million, US$540 million and US$1.08 billion respectively. Discounted to 2026 at 8%, the modelled exposure is lower because the deductions are used over time, but remains material. These numbers are not forecasts of actual avoidance. They are an exposure envelope demonstrating why legislation is required before the taxable cash flow begins.

Central conclusion: the PSC ring fence protects the petroleum bargain; the fiscal ring fence protects the national tax base. Suriname needs both.

Prior GLIAG Work — Incorporated by Reference, Not Repeated

This essay builds directly on two recent GLIAG publications and does not reproduce their full argument:

• Distinguishing Contractual and Fiscal Rings in Suriname — establishes the legal and conceptual distinction between the PSC contract ring and the statutory fiscal ring.

• Suriname’s Petroleum: Creating a Legal Fiscal Ring Fence — sets out the policy case and a 24-month legislative workstream for a resilient fiscal boundary.

• Transforming Suriname: Legal and Tax Reforms for Oil Prosperity — provides the wider tax-modernisation, anti-avoidance and institutional context.

1. Two Instruments, Two Legal Locations, Two Risks

1.1 The PSC ring fence

A PSC ring fence is created by contract. It determines which petroleum operations belong to a specific contract, which expenditures can enter that contract’s recoverable-cost account, which production is available to reimburse those expenditures, and how profit petroleum is calculated after royalty and cost recovery. Its legal home is the PSC and its accounting procedure.

Its primary purpose is not corporate income tax. Its purpose is to preserve the integrity of the production-sharing mechanism. Without a contract ring, a contractor could attempt to recover unsuccessful exploration costs from one acreage position against production from a different successful contract, thereby shrinking profit petroleum in the successful contract. A well-drafted PSC prevents that migration of costs.

The ring therefore answers a petroleum-accounting question: ‘May this expenditure be recovered from this petroleum?’ The answer depends on nexus to the Contract Area, approved work programmes and budgets, the defined categories of petroleum expenditure, allocation rules, cost-recovery ceilings and audit rights.

1.2 The fiscal ring fence

A fiscal ring fence is created by statute, regulation or binding tax ruling. It determines which income and deductions may be aggregated when calculating taxable profit. It addresses corporate income tax, not the physical allocation of cost oil. Its legal home is the Income Tax Act and petroleum tax rules.

The fiscal ring answers a different question: ‘May this deduction reduce the taxable profit of this petroleum project?’ A cost may be non-recoverable under the PSC yet still be claimed as a tax deduction unless the tax law says otherwise. Conversely, a cost may be recoverable under the PSC but deductible for tax on a different timing basis. The two systems overlap economically but are not legally identical.

This distinction is decisive. A PSC ring fence can protect profit oil while a weak tax boundary still allows erosion of corporate income tax. The State may therefore win inside the PSC ledger and lose inside the tax ledger.

Feature	PSC Ring Fence	Fiscal Ring Fence	Primary Risk Controlled
Legal source	Production Sharing Contract and accounting procedure	Income-tax law, petroleum tax provisions and regulations	Confusion of contractual and statutory rules
Boundary	Contract Area; sometimes separate commercial fields	Project, contract area, licence, taxpayer or petroleum sector	Cross-project loss relief
Main calculation	Royalty, cost oil, profit oil, R-factor and recoverable expenditure	Taxable income, depreciation, losses, interest and withholding taxes	Tax-base erosion and tax deferral
Administration	Staatsolie/SHI operations, cost audit and PSC governance	Tax authority, Ministry of Finance and courts	Institutional gaps
Failure consequence	Excess cost recovery and reduced profit petroleum	Reduced or delayed corporate income tax	Fiscal value leakage

2. Why Suriname’s PSC Ring Fence Is Strong

The strongest argument for Suriname’s PSC design is structural rather than rhetorical. The contract does not rely on a single sentence saying that costs are ‘ring-fenced.’ It constructs the ring through interacting definitions, rights, accounting obligations and economic consequences.

First, the contract is geographically and legally bounded. The contractor receives the exclusive right to conduct petroleum operations within a defined Contract Area. Petroleum expenditures arise from those operations, and cost recovery is made from petroleum produced from that same area. This creates the essential closed loop: area-specific operations, area-specific expenditure, area-specific production and area-specific recovery.

Second, the contractor bears sole risk. If no commercial field is established, or if cost oil is insufficient to reimburse expenditure, Staatsolie has no obligation to repay the shortfall. That provision prevents the failed economics of one contract from becoming a claim against the State or another successful contract.

Third, the accounting procedure requires expenditures to be identified by commercial field when more than one field exists. Shared expenditures must be allocated by a specified method. This is superior to a purely block-wide undifferentiated ledger because it preserves visibility inside the contract and enables economic testing, development-plan scrutiny and abandonment allocation at field level.

Fourth, the contract requires separately identifiable accounting records for all receipts and expenditures connected with petroleum operations. It also gives audit access to affiliate support and permits verification of affiliate charges. This is essential because the practical strength of any ring fence depends on cost classification and related-party pricing, not merely the formal geographic boundary.

Fifth, petroleum expenditure excludes or controls items that should not automatically enter cost recovery, including financing interest in the published Block 45 form. The exclusion of interest from development and operating expenditure is particularly important: it prevents capital-structure decisions from automatically enlarging the cost-oil account.

Sixth, the PSC separates the State’s revenue instruments. Royalty is taken before cost recovery; cost oil is capped; remaining petroleum becomes profit oil; and the contractor then remains subject to income tax. The layers are mutually reinforcing. A contractor cannot use the tax system to rewrite the cost-oil ceiling, and it cannot use cost recovery to extinguish the royalty.

Seventh, the ring is auditable and operational. Work programmes, budgets, operations-committee approvals, petroleum-expenditure accounts, inventory controls, affiliate documentation and time-limited audit procedures form a complete governance chain. Internationally, many regimes state that costs belong to a contract area but do not support that statement with the same depth of accounting machinery.

2.1 Why ‘perfect’ must mean fit for purpose

No fiscal instrument is literally perfect for all circumstances. The defensible professional claim is that the Suriname PSC ring fence is exceptionally well designed for its intended purpose: protecting the production-sharing calculation at contract-area level while retaining field-level accounting visibility. Its strength lies in completeness, internal consistency, auditability and economic consequence. It should be defended, maintained and modernised technically — not replaced because the tax law has a separate weakness.

3. International Comparison: What Other Regimes Actually Ring-Fence

Jurisdiction	Core Ring-Fence Content	Lesson for Suriname
Guyana — Stabroek PSA	The 2016 agreement operates primarily as a block-wide cost-recovery system. Development costs from successive Stabroek projects can be recovered against block production, subject to the 75% cost ceiling. The broad block boundary accelerated development but permits large cost banks to be absorbed by production from multiple fields. Guyana’s published audits show that the key governance burden shifts to cost verification and allocation.	Suriname’s published PSC form is stronger on explicit field-level cost identification within the Contract Area. A fiscal tax ring remains a separate issue in both countries.
Indonesia	Traditional cost-recovery PSCs generally ring-fence costs by contract area. Gross-split PSCs reduce classical cost recovery but still require contract-specific production and fiscal accounting.	Suriname follows the contract-area discipline while retaining a profit-sensitive R-factor and explicit accounting controls.
Ghana	Petroleum agreements and tax rules generally use contract areas and separate petroleum operations, but shared infrastructure and consolidated developments require detailed allocation rules.	Suriname should retain contract-area cost recovery and legislate equivalent clarity for taxable income.
Australia — PRRT	The Petroleum Resource Rent Tax is project-based. Transfer of exploration expenditure is permitted only through complex statutory rules and ownership continuity tests. The regime demonstrates that a project ring can coexist with carefully limited transferability.	Suriname can allow narrowly defined transfers only where Parliament deliberately chooses them; silence should not create automatic cross-block relief.
United Kingdom	Ring Fence Corporation Tax isolates upstream oil and gas profits from other corporate activities. Supplementary Charge and energy-profits rules sit on top. Within the UK upstream ring, consolidation is broader than a field-by-field regime.	The UK shows that a statutory sector ring protects petroleum profits from non-petroleum losses, but Suriname should use a tighter contract-area boundary during its early offshore phase.
Norway	Norway taxes upstream activity under a special petroleum tax system with extensive consolidation across the Norwegian Continental Shelf, but combines this with high rates, neutral loss treatment, strong information systems and exceptional tax administration.	Norway’s consolidation cannot safely be copied without Norway’s institutional capacity, loss-refund design and mature taxpayer base.
Brazil	Concession and production-sharing projects maintain licence/contract accounting, while corporate tax remains governed by general federal rules. Cost recovery under PSCs is contract-specific; transfer pricing and thin-capitalisation are handled statutorily.	The Brazilian experience reinforces the need to align contract accounting with an explicit tax boundary.
Trinidad and Tobago	Petroleum taxation uses sector-specific taxes, allowances and ring-fence concepts, with detailed restrictions on management fees, allowances and petroleum operations.	Suriname can borrow the discipline of petroleum-specific deductions without importing the full complexity of Trinidad’s mature regime.

The comparison supports a precise conclusion. Suriname’s PSC ring is not weak because it is contract-area based; contract-area cost recovery is the international norm for PSCs. Guyana’s Stabroek system is economically broader because one very large block contains many projects and discoveries. Norway and the United Kingdom allow broader tax consolidation, but they do so inside highly developed statutory systems with powerful tax administrations. Suriname’s immediate need is not to imitate broad consolidation. It is to protect the first large offshore tax base while administrative capability catches up.

4. Why a Fiscal Ring Fence Is Needed Now

GranMorgu changes the risk profile of Suriname’s tax system. Before a major producing project exists, cross-block losses mainly represent deferred assets on company balance sheets. Once a large profitable project begins, those losses can become immediate claims against tax payable. The transition from exploration country to producing country is therefore the last practical moment to define the boundary.

The statutory rule should begin from a simple principle: income and deductions attributable to a petroleum agreement must be computed separately from every other petroleum agreement and from all non-petroleum activity. Losses remain within the originating ring and may be carried forward only against future income of that ring, subject to ownership continuity and anti-trafficking rules.

A contract-area fiscal ring is preferable to a field-by-field tax ring for Suriname’s first generation of offshore developments. It aligns with the PSC, reduces duplicate accounting, permits efficient shared infrastructure and tie-backs inside the same block, and avoids premature fragmentation. Field-level accounts should nevertheless remain mandatory for cost allocation, decommissioning and economic monitoring.

The ring must apply per contractor party, not only per operator. Each participant has its own tax position, financing and affiliates. A project ring that exists only in the operator’s joint-account ledger but not in each participant’s tax return would be incomplete.

4.1 Recommended statutory architecture

1. Define each Petroleum Agreement and its Contract Area as a separate petroleum tax project.

2. Require a separate tax computation, balance sheet, fixed-asset register, loss memorandum and financing schedule for each project.

3. Prohibit deduction of exploration, development, operating, financing and abandonment expenditure from another project unless a specific statutory exception applies.

4. Allow shared-service and common-infrastructure costs only under pre-approved arm’s-length allocation keys supported by contemporaneous documentation.

5. Carry losses forward within the ring; do not permit group relief, merger relief or change-of-control trafficking to move them without ministerial and tax-authority approval.

6. Limit net interest deductions using both an arm’s-length test and an earnings-based ceiling, with stricter rules for related-party debt.

7. Apply OECD-aligned transfer-pricing documentation, beneficial-ownership tests and withholding-tax rules to affiliate services, insurance, marketing and financing.

8. Coordinate PSC cost audits and tax audits through a joint petroleum revenue assurance unit while preserving legal responsibilities.

9. Create transitional rules that protect legitimate vested rights but prevent new cross-block deductions after the effective date.

10. Enact before first oil, with regulations, forms and digital project ledgers operational at least twelve months before the first GranMorgu tax return.

5. Where Fiscal Value Can Leak Under the Present Framework

Leakage Channel	Mechanism	Fiscal Consequence
Cross-block exploration losses	A contractor with historic dry-hole or seismic expenditure in another Suriname block may seek to offset those losses against GranMorgu taxable income. The PSC prevents recovery of those costs from GranMorgu cost oil, but the tax return may still attempt consolidation if the statute does not prohibit it.	Permanent or deferred CIT loss equal to 36% of the deduction used.
Cross-project development losses	A later gas, refinery, pipeline or offshore project may generate early losses while GranMorgu is profitable. Common ownership can create pressure to aggregate them.	Tax revenue from the mature project finances the risk of the new project without an explicit parliamentary decision.
Related-party debt	An affiliate can capitalise a Suriname participant with excessive debt, charging interest that reduces taxable income while profit is repatriated as deductible finance cost.	Each US$100m of excess deductible interest exposes US$36m of CIT, before withholding-tax effects.
Affiliate technical and management charges	Head-office, engineering, procurement, IT, insurance and marketing services may be priced above arm’s length or allocated using unsuitable global keys.	Repeated annual base erosion; difficult to audit after records and personnel move.
Transfer of tax losses through restructuring	Shares or entities holding unused losses can be sold, merged or reorganised into profitable structures.	Creates a market in tax attributes unrelated to the underlying petroleum risk.
Decommissioning timing	Accelerated deductions or provisions may reduce current tax long before cash is placed in a protected abandonment fund.	Time-value loss and counterparty risk if funds are not secured.
Foreign-exchange and hedging allocations	Group treasury transactions may allocate losses to Suriname while gains arise elsewhere.	Volatile and opaque deductions disconnected from project operations.
Marketing and offtake pricing	Affiliate crude sales, quality adjustments, freight and marketing fees can lower the taxable realised price.	Simultaneous erosion of tax and profit-oil valuation if controls are not aligned.
Common infrastructure allocation	FPSO, subsea, shorebase, pipeline or logistics costs shared across projects can be directed disproportionately toward the profitable ring.	Hidden cross-subsidy through cost allocation rather than explicit loss transfer.
Audit limitation and data fragmentation	Different agencies may hold PSC, customs, VAT, payroll, banking and tax data without an integrated taxpayer-project identifier.	Leakage remains undetected even where substantive law is adequate.

6. GranMorgu Fiscal Exposure Model

6.1 Purpose and limitations

The model below is an exposure model, not a prediction of taxpayer behaviour and not a reconstruction of the confidential Block 58 fiscal model. It uses public project information and transparent stylised assumptions to answer one narrow policy question: how much corporate income tax can be lost or deferred if deductions from outside the GranMorgu fiscal ring are allowed to enter its taxable base?

Public anchors are a project investment of approximately US$10.5 billion, FPSO capacity of 220,000 barrels per day, first oil in 2028, a 6.25% royalty and a 36% income-tax rate. The production profile is scaled to 750 million barrels. A stylised contractor entitlement is used solely to establish that sufficient taxable income exists to absorb imported losses. It is not the actual R-factor schedule, profit-oil split or contractor forecast.

Assumption	Model Input
Recoverable production	750 million barrels, stylised profile
First oil	2028
FPSO capacity	220,000 bbl/d
Real oil price	US$65/bbl
Development CAPEX	US$10.5bn
Operating cost	US$10/bbl
Royalty	6.25% of gross production
Corporate income tax	36%
Discount rate	8% nominal/analytical
External loss pools	US$0.75bn / US$1.50bn / US$3.00bn

6.2 Results: cross-block loss exposure

Scenario	Imported Loss Pool	Losses Absorbed	Nominal CIT Exposure	PV Exposure to 2026
Low exposure	US$750 m	US$750 m	US$270 m	US$135 m
Central exposure	US$1.50 bn	US$1.50 bn	US$540 m	US$262 m
High exposure	US$3.00 bn	US$3.00 bn	US$1.08 bn	US$494 m

The arithmetic is direct. A US$1.50 billion imported loss pool multiplied by the 36% income-tax rate produces US$540 million of nominal corporate-income-tax exposure. The timing of absorption depends on the project’s taxable-income profile, so the present value is lower than the nominal figure. The exposure is nevertheless large relative to Suriname’s present fiscal capacity.

The central case should not be read as an allegation that US$1.50 billion of losses exists or will be claimed. It is a policy stress test. Offshore exploration wells, seismic programmes, licence acquisition, financing and future developments can produce loss pools of this order across a portfolio. The legislation should decide ex ante whether GranMorgu may be used to monetise them.

The sensitivity is linear: each US$100 million of otherwise inadmissible deduction reduces nominal income tax by US$36 million. This rule of thumb is more durable than any single project forecast and should be used by Parliament and the Ministry of Finance when evaluating exceptions.

6.3 Deferral is also a real fiscal cost

Deduction Shifted into GranMorgu	Nominal CIT Deferred	PV Cost if Recovered 8 Years Later (8%)
US$500 m	US$180 m	US$83 m
US$1.00 bn	US$360 m	US$166 m
US$1.50 bn	US$540 m	US$248 m
US$3.00 bn	US$1.08 bn	US$497 m

Marcel P.T. Chin-A-Lien – Principal Founding Partner & Chief Architect, GLIAG N.V. – Golden Lane Investments Advisory Group

Even where the tax is ultimately recovered, an eight-year delay transfers financing value from the State to the taxpayer. Suriname must borrow, cut spending or postpone investment while the taxpayer enjoys the use of the cash. A fiscal ring therefore protects both the amount and the timing of public revenue.

7. Legislative Design: What, How and When

7.1 What should be amended

The Income Tax Act should contain a dedicated petroleum chapter or schedule defining project-level taxable income. The Petroleum Law should cross-reference that tax boundary without attempting to place the entire tax regime inside the PSC. Regulations should prescribe project accounts, cost-allocation methods, transfer-pricing documentation, loss registers and filing forms.

The fiscal ring should not be created only through individual tax rulings. Rulings are useful for implementation, but the core boundary affects parliamentary revenue rights and should have a clear statutory basis. Contract stabilisation clauses should not prevent a generally applicable anti-erosion rule that preserves the existing 36% tax bargain rather than increasing the tax rate.

7.2 How the rule should operate

• Separate taxable income shall be calculated for each Petroleum Agreement.

• No loss, allowance, depreciation, interest expense or other deduction attributable to one Petroleum Agreement may be deducted from income attributable to another.

• Expenditure attributable to non-petroleum activity may not enter a petroleum project.

• Common costs shall be allocated under an arm’s-length method approved by the tax authority and petroleum regulator.

• Losses may be carried forward indefinitely or for a defined long period within the same ring, but remain subject to ownership-continuity and business-continuity tests.

• Decommissioning deductions shall correspond to cash contributions to an approved, segregated fund or to verified expenditure.

• Related-party financing shall satisfy arm’s-length, beneficial-ownership and earnings-stripping tests.

• Transfers of participating interests shall preserve project losses only in proportion to continuing economic ownership, unless otherwise approved.

• Taxpayer, operator, customs and PSC identifiers shall be linked in a single digital petroleum revenue ledger.

• Material non-compliance shall permit penalties, interest, reassessment and denial of deductions.

7.3 When

Timing	Action
0–3 months	Cabinet policy decision; establish joint Ministry of Finance–Staatsolie/SHI–Tax Authority drafting team; commission legal compatibility review.
3–6 months	Publish consultation paper and exposure model; map all existing PSCs, tax rulings, contractor entities and accumulated losses.
6–12 months	Draft and consult legislation, regulations and transitional provisions; create petroleum revenue assurance unit.
12–18 months	Parliamentary enactment; issue forms, allocation regulations, transfer-pricing guidance and advance-ruling protocol.
18–24 months	Test digital project ledgers, train auditors, perform dry-run GranMorgu filings and reconcile PSC and tax accounts.
Before first oil / first taxable year	Fiscal ring fully effective, with no ambiguity over imported losses.

8. Administration: A Ring Fence Is Only as Strong as Its Data

The IMF’s FARI methodology evaluates petroleum fiscal regimes at project level, using project costs, production, prices, financing and tax-accounting rules. The methodology explicitly warns that standard models often assume away international tax planning and ring-fence weaknesses. Suriname should therefore use a FARI-style model not only for policy design but also for revenue assurance: expected project tax should be compared annually with filed tax, audited costs and actual production.

A Petroleum Revenue Assurance Unit should combine tax auditors, petroleum accountants, economists, transfer-pricing specialists, reservoir engineers, customs analysts and legal counsel. It should not replace the tax authority or Staatsolie/SHI; it should connect their data and establish a single risk view.

The unit’s minimum data set should include approved work programmes and budgets, cost-recovery statements, lifting and valuation data, partner billings, affiliate invoices, debt agreements, hedging, customs declarations, VAT records, payroll, fixed assets, abandonment contributions and beneficial ownership. The project identifier should follow every transaction from customs entry to PSC account to tax return.

Audit timing is critical. Cost and transfer-pricing audits conducted ten years after the transaction will recover less, cost more and face missing evidence. Suriname should conduct rolling risk reviews during development and annual integrated audits from first production.

9. Conclusions and GLIAG Position

Suriname should not weaken or redesign its PSC ring fence merely because public debate has identified a fiscal-law gap. The contract ring and the fiscal ring are different instruments. The published Suriname PSC form demonstrates a coherent contract-area system: exclusive operations in a defined area, area-linked cost recovery, sole contractor risk, field-level cost identification, separately identifiable accounts, affiliate audit and layered royalty/profit-oil/tax revenues.

International comparison confirms that this is a strong PSC architecture. Guyana’s Stabroek PSA is broader in economic effect because a single enormous block contains multiple producing projects and permits block-wide cost recovery. Norway and the United Kingdom permit broader tax consolidation, but only inside mature, high-capacity systems. Australia’s project-based rent tax demonstrates that narrow rings and controlled transfer rules can coexist.

Suriname’s unresolved task is statutory. Before GranMorgu taxable income emerges, the Income Tax Act should state plainly that each petroleum agreement is a separate tax project. Losses and deductions should remain where the underlying risk was taken. Exceptions should be deliberate, narrow, transparent and administrable.

The GranMorgu stress test shows why the issue is urgent. At the existing 36% rate, a US$1.50 billion imported loss pool exposes US$540 million of nominal corporate income tax. A US$3.00 billion pool exposes US$1.08 billion. Even temporary deferral carries a large present-value cost. Suriname cannot afford to discover the meaning of its tax boundary during the first major assessment or in litigation after the revenue has already been delayed.

The policy is therefore neither anti-investor nor retroactive. A clear fiscal ring preserves the bargain that investors already accepted: project risk is rewarded from project success, while the State receives its agreed royalty, profit petroleum and tax. Clarity lowers disputes, strengthens bankability and prevents one taxpayer’s portfolio strategy from becoming an unlegislated charge on the Republic.

GLIAG doctrine: A strong PSC ring fence protects the petroleum equation. A strong fiscal ring fence protects the Republic. The first must be preserved; the second must now be enacted.
