Private Investment Act Lawyer | Advisory for Sponsors, Lenders, and Government Counterparties
The Act on Public-Private Partnerships in Infrastructure (사회기반시설에 대한 민간투자법, commonly called the "Private Investment Act" or 민간투자법) sets the legal framework for private capital to build, operate, or finance roads, rail, schools, and other public infrastructure in Korea. The central legal question in almost every matter is how the concession agreement allocates construction risk, demand risk, and financing risk between the private operator and the government. Because these projects run for 20-30 years and involve multiple layers of financing agreements, most disputes surface only years into operation — over toll revenue shortfalls, rate-of-return recalculation, or the government's termination and buy-back rights.
Private Investment Act | BTO, BTL, and BOT — choosing and negotiating the right structure
The Private Investment Act permits several project structures, and the choice determines who bears demand risk and how the operator gets paid. Most disputes we see trace back to a mismatch between the structure chosen at the proposal stage and how the project actually performs once operational.
| Ownership transfer | To government upon completion |
| Revenue source | User fees/tolls collected by operator |
| Demand risk | Borne mainly by operator (unless MRG applies) |
| Typical use | Roads, ports, rail with tariff revenue |
Older BTO projects negotiated Minimum Revenue Guarantee (MRG) clauses; post-2009 policy changes largely replaced MRG with a Standard Cost Compensation scheme (표준비용보전제도).
| Ownership transfer | To government upon completion |
| Revenue source | Government lease payments over lease term |
| Demand risk | Borne by government, not operator |
| Typical use | Schools, public housing, military facilities |
Because payment does not depend on usage, BTL disputes tend to center on construction cost adjustment and the annual government payment formula rather than demand shortfalls.
| Ownership transfer | Deferred (BOT) or never (BOO) |
| Revenue source | Operator-collected fees during operation period |
| Demand risk | Borne by operator |
| Typical use | Less common; select energy/utility facilities |
This structure is used less frequently in Korean infrastructure PPPs but appears in specific sector concessions where retained ownership during the concession term is negotiated.
Private Investment Act | What actually gets negotiated in a concession agreement
The concession agreement (실시협약) is the master contract that implements the government's approval of a private investment project, and its terms often matter more in a dispute than the statute itself.
Concession period and rate-of-return recalculation
The concession period and the operator's target rate of return are fixed in the agreement at financial close, but many long-term concessions include periodic recalculation mechanisms tied to actual traffic or usage data. Disputes arise when the government and operator disagree on which inputs (interest rate changes, inflation index, actual demand) trigger a recalculation and how it should be applied.
Change of law and change in circumstances clauses
Because these projects run for decades, concession agreements typically include mechanisms to adjust compensation if a change in law or unforeseen circumstances (such as a new competing facility affecting demand) alters the project's economics. Whether a particular event qualifies, and how compensation is calculated, is frequently the crux of a claim against the government.
Termination and buy-back valuation
The Act and the concession agreement together give the government early termination and buy-back rights in cases of serious breach, insolvency, or public necessity, but the compensation formula on termination is set by contract, not statute. Sponsors and lenders need to review the buy-back valuation clause carefully at the financing stage, since it directly affects lender recovery in a downside scenario.
Private Investment Act | Risk allocation: construction, demand, and financing risk
The Act does not itself dictate risk allocation — it authorizes the framework within which the concession agreement allocates risk. Understanding how each risk category is typically shared helps a sponsor evaluate a proposal or a lender assess exposure before financial close.
Construction cost overrun and completion risk
Construction risk is generally allocated to the special purpose company (SPC) and its construction contractor through a fixed-price EPC or turnkey contract, with the government rarely absorbing cost overruns absent a change order it approved. Reviewing the interface between the concession agreement's completion test and the underlying construction contract is essential before signing.
Demand risk and the shift away from MRG
Older BTO projects negotiated Minimum Revenue Guarantee (MRG) provisions under which the government compensated the operator if actual traffic fell below a guaranteed threshold. Following 2009 policy reforms, most new BTO concessions replaced MRG with narrower cost-recovery mechanisms, shifting more demand risk onto the private sector — a point that materially affects a sponsor's financial model and a lender's covenant structure.
Refinancing gain-sharing clauses
Many concession agreements require the operator to share a portion of any refinancing gain with the government if financing conditions improve after financial close. Disputes over how the gain is calculated, and whether a refinancing triggers the clause at all, are common in later-stage advisory work.
Private Investment Act | The government's approval, supervision, and PIMAC review role
Because public funds and public infrastructure are involved, the competent authority retains ongoing supervisory powers that private-sector counterparts do not have in an ordinary commercial contract.
PIMAC feasibility review and project approval
Proposed projects generally go through a feasibility and value-for-money review by the Public and Private Infrastructure Investment Management Center (PIMAC) before the competent authority approves the implementation plan (사회기반시설에 대한 민간투자법 제8조 및 관련 시행령). Understanding what PIMAC's review actually assessed helps explain why certain risk allocations were built into the original request for proposal.
Ongoing supervision and reporting obligations
The competent authority retains the right to inspect the facility, require reports on operation and financial status, and order corrective measures during the operation period. Operators sometimes underestimate how much documentation these supervisory rights require, which becomes relevant if a dispute later turns on whether the operator complied with its obligations.
Dispute resolution: administrative litigation vs. arbitration
Whether a dispute with the government proceeds as administrative litigation (challenging an administrative disposition such as a termination order) or as a contractual arbitration/civil claim under the concession agreement depends on how the specific dispute is framed. This distinction affects the applicable procedure, timeline, and available remedies, so it is usually the first issue to resolve when a conflict with the competent authority arises.
Private Investment Act | From proposal review to operational dispute
We review the request for proposal, draft concession agreement, or existing agreement (if the project is already operational) to identify the specific provisions relevant to your question.
For sponsors and lenders, we analyze how construction, demand, and financing risk are allocated under the proposed or existing structure, and flag terms that deviate from standard market practice.
We assist in negotiating concession terms with the competent authority or PIMAC, or in preparing formal correspondence and submissions where a dispute is emerging.
If a conflict has already arisen, we assess whether administrative litigation, arbitration, or negotiated settlement is the appropriate track given the nature of the government action involved.
For long-running projects, we provide periodic review of compliance obligations, refinancing clauses, and recalculation triggers as the project matures.
Private Investment Act | How advisory fees are calculated
Fees are generally set based on the volume and complexity of the concession agreement and related financing documents reviewed, and the scope of the legal opinion requested.
For ongoing negotiation support during a bid or amendment process, fees are typically structured as a retainer for the negotiation period, scaled to the project's complexity.
If a dispute proceeds to administrative litigation or arbitration, fees are typically split between a retainer at engagement and a contingent or success-linked fee tied to the outcome, calculated case by case.
For sponsors or operators seeking continuous legal support through the operation period, a periodic retainer arrangement can be structured based on expected scope of work.
Separate from legal fees, actual costs such as expert valuation fees, translation, and filing fees are billed at cost.
