Private capital accounts for a significant share of global foreign direct investment (FDI). States generally welcome private capital investment which may support economic growth and development, but that position can change if policy priorities or the geopolitical climate shifts.
When the interests of States and foreign private capital investors diverge and investors face losses, investors may look to a number of different legal avenues for recourse, including international investment treaties. Investment treaties typically contain:
Investment treaties can therefore enable private investors to bring a claim for damages before an independent tribunal, when their investment has been undermined by host-State action which violates the substantive protections in an investment treaty. Significantly, there does not need to be a contract between the investor and the host-State for the investor to benefit from these protections.
Particularly in the current climate of heightened geopolitical risk, increased nationalism, and regulatory flux as the world grapples with the climate crisis, private capital investors must anticipate how investor-State disputes may unfold over the lifecycle of an investment, including during deal structuring, deal closing, investment management, and investment exit.
After identifying a prospective target, a private capital firm typically considers how to structure the transaction. A conventional private capital structure involves (for a number of good reasons, including operational flexibility, tax, and liability issues):
Investment structures may involve other "entities" without legal personality, such as trusts, foundations or unincorporated associations. These structures can raise complex questions when considering rights available to the different entities within it under investment treaties. In particular:

Investment treaties typically only cover nationals of, and entities incorporated or established in, a State party to the treaty. The nationality of the investor is therefore key. Treaties may include additional requirements, including that the investor: (i) has “substantial business activities” in the home-State; and (ii) is “controlled” by nationals of the home-State.

Investment treaties usually cover “every kind of asset” in the host-State, including shares, claims to money (which may include debt), property (which may include security rights), and licences. Treaties may cover indirect investments, as well as direct investments.
In a private capital investment context, when considering political risk, the key question is whether all of the upstream partners’ interests in the fund / holding companies are protected directly under a treaty between their home-State and the host-State, and if not, whether any entity downstream in the structure may satisfy the definition of "investor" under an applicable treaty so that they may bring a claim if needed.
Notably, tax-driven structures often mean investments involve offshore jurisdictions that form part of the territories of another State or are dependent on another State, such as Hong Kong, and the Cayman Islands. However, the treaties of that State may not extend to those territories / dependencies. These issues must all be considered at the outset of an investment when tax-structuring so that investors may be able to rely on treaty protections if needed down the line.

In Mason Capital v. Korea, Mason Capital alleged that the Korea's interference in a 2015 merger between Samsung C&T Corp. and Cheil Industries Inc breached the protections in the US-Korea free trade agreement and damaged Mason's investment in the Samsung Group. Korea challenged the GP’s status as a covered investor. The tribunal determined that, under the applicable laws (being the laws of Korea and the Cayman Islands) and agreements, the GP was a covered investor, in particular it was the ultimate legal owner and controller of the target companies in Korea as the trustee of all assets in the fund domiciled in the Cayman Islands. |
Host-State FDI screening is often a condition precedent to closing the transaction. National security and other domestic political concerns can lead to approval delays, conditions or refusals.
In an increasingly competitive market, this can create fertile ground for disagreements. For example, disputes may emerge when investors believe an FDI review contravenes treaty protections. In this circumstance, key questions private capital investors will need to consider are:
|
In Global Telecom Holding S.A.E v Canada, the claimant claimed that the State’s FDI review process which prevented it taking voting control of its investment in a telecommunications company violated several treaty protections. The tribunal determined that the State’s FDI process did not violate the treaty, as it was not arbitrary, the investor had been accorded due process and there was evidence of valid national security concerns underlying the decision. |
Depending on the particular investment strategy, a private capital firm will typically hold and/or manage the investment for a 3 to 10-year period. During this time, for an equity investment, the investor may control the board and pursue operational improvements targeted at reducing costs and increasing revenue, to enhance value. However, in a debt investment context, the investor may simply hold the investment to obtain value accretion. In this holding and management period, host-State actions that alter the investment environment may trigger investor-State disputes.
Common State actions that may prompt an investor-State dispute include:
|
Changes in law or regulationsIn 9Ren Holdings v Spain, a portfolio company of a VC firm claimed that changes to the applicable tariff regulations adversely impacted its investment in a solar project and violated treaty protections. The tribunal determined that the State had violated treaty protections and awarded compensation representing the change in value of the investment due to the reduced tariffs. In Gramercy Funds Management v. Peru, a PE management entity and portfolio company claimed that changes to the repayment scheme for certain government-issued land reform bonds impacted the value of their investment in those bonds and breached treaty protections. The tribunal determined that the State had violated treaty protections and awarded compensation representing the purchase price of the bonds when purchased plus interest compounded to arrive at the current value of the bonds.
Introducing taxes, levies or fines, or revoking tax exemptions or concessionsIn Ampal-American v Egypt, the investment arm of a bank claimed that the State's revocation of a long-term tax exemption license violated treaty protections. The tribunal found that operating in a tax-free zone was integral to the claimant’s investment structure at the time of investment, and ruled that revoking the exemption license amounted to expropriation, thus breaching the treaty.
Cancelling or not renewing licenses or permitsIn Nachingwea Nickel Holdings & Ors v. Tanzania, portfolio companies of a private equity firm joint venture claimed that the revocation of a mining licence for a project violated treaty protections. The tribunal determined that the State had violated treaty protections and awarded compensation in the form of historical costs incurred in exploring and developing, and applying a multiplier to value the future prospects of the project. |
The investment exit – which may be via an initial public offering or a strategic sale to a third party - is a critical step in the private capital lifecycle. This is when the GP is compensated for its efforts, LPs receive their capital and yield back, and liquidity is generated for future ventures. Host-State approvals or oversight are often key at this stage, particularly where the investment is in a ‘strategic’ or ‘sensitive’ sector. Disputes may arise at this stage too, and this is likely to be the subject of heightened scrutiny in the immediate future given the number of delayed exits.
For private capital firms, anticipating State scrutiny of, or influence over, exits — and signalling treaty protections when necessary — is critical.
|
In PL Holdings v. Poland, a Luxembourg portfolio company of a European private equity fund claimed that the State regulator had expropriated its investment (a bank) by forcing a sale to a designated third party, which deprived the PE fund of its ability to maximise its return on exit through an IPO. The State argued that these measures were necessary to protect the prudent and stable management of the bank. The tribunal determined that there had been an expropriation of the investment, and awarded the PE firm compensation calculated on the difference between the return the PE firm could have achieved under an IPO and the actual sale price received. |
Evolving State policy objectives and the changing geopolitical climate may cause private capital firm and States’ interests to diverge. Private capital firms should be alive to these issues, particularly at the deal structuring stage, to manage such risk with investment treaty protection.
