PIK’s warning label: what private credit’s flexible structures may be hiding

Private markets have long relied on structural flexibility, but not every flexible structure makes risk easier to understand. Payment-in-kind, or PIK, structures have become one of the examples of that tension. By allowing borrowers to meet interest obligations through additional debt or equity rather than immediate cash payments, PIK can ease short-term cash pressure. It can also make it harder to judge whether a firm is managing liquidity carefully or showing signs of deeper financial strain. That distinction matters across private equity and private credit. For managers, lenders, investors, and administrators, the rise of PIK structures is a question of transparency, modelling accuracy and governance discipline.

A financing tool gaining wider relevance

Our latest study of 300 senior executives at private equity fund managers, collectively overseeing $3.511 trillion in assets under management, found that 86% expect PIK prevalence within their private credit exposure to rise over the next two years. Most expect a modest increase, with 82% anticipating slight growth and 4% predicting a dramatic rise. The remaining 14% expect usage to stay unchanged.

This direction of travel reflects the conditions facing portfolio companies and their sponsors. Anatoly Sorin, UK Head of Loan Agency and Bond Trustee Services at Ocorian, says private equity fund managers are “doing everything they can to support portfolio companies through a prolonged period of higher financing costs.”

PIK structures can form part of that response. They give borrowers breathing room by replacing current cash interest payments with additional debt or equity obligations. But the appeal of the structure is inseparable from its risk. Sorin cautions that “this flexibility does come with a warning label”.

The risk is not PIK itself, but what it can obscure

A borrower using PIK is not automatically distressed. The concern is that postponed cash interest can reduce the visibility of pressure building beneath the surface. The survey found that 90% of respondents agree there is a growing risk that PIK usage masks true borrower distress. Within that group, 16% strongly agree that delayed cash obligations make it difficult to distinguish between proactive capital management and severe liquidity struggles.

PIK can be a legitimate tool for managing cash flow, yet it may also signal vulnerabilities in corporate balance sheets. For investors, the practical question is what a PIK structure says about the borrower’s financial position and how clearly that assessment is being reported.

The more common these structures become, the more important it will be for managers to explain their purpose, impact and trajectory. A contractual feature can quickly become a transparency issue if investors cannot see how it affects cash flow, leverage and portfolio company resilience.

Waterfall modelling becomes more demanding

The implications extend beyond borrower analysis. PIK interest compounds, and that compounding can affect preferred return hurdles, distribution waterfalls and calculations of realised versus unrealised gains – measures that drive performance fees, including carried interest.

This is where a financing decision could become a fund administration issue. Only 17% of firms surveyed say they have robust automated systems capable of fully accounting for PIK compounding within waterfall modelling. Another 39% can model PIK but require significant manual adjustment, while 32% rely entirely on third-party providers. A further 10% identify this as a gap in their current setup.

Those figures suggest a widening gap between the use of sophisticated financing structures and the systems needed to model their effects cleanly. Manual intervention may be manageable in limited cases, but it raises questions around consistency, review and auditability when PIK exposure grows.

Sorin argues that firms’ “operational and technological capabilities must keep pace,” whether handled in-house or outsourced, so waterfall and carry calculations remain “accurate, consistent and transparent.”

Governance cannot be an afterthought

PIK also raises questions for governance and oversight, particularly where structures affect fund economics and third parties are involved.

Abi Reilly, Partner, Regulatory & Compliance at Ocorian, says governance and oversight need to “remain front of mind” as firms manage the demands created by PIK structures. She adds that firms must be able to evidence how these structures are “monitored, modelled and reported on,” particularly where greater complexity and third-party support are involved.

Oversight is about identifying where PIK appears in a portfolio and demonstrating that its effect on valuations, distributions, reporting and carried interest calculations is understood and consistently documented.

The broader implication for private markets

PIK structures are likely to remain part of the private markets’ toolkit while managers seek ways to support portfolio companies through higher financing costs. Their growing use does not necessarily point to poor credit quality. It does, however, raise the standard for transparency, modelling and governance.

For fund managers, the task is to ensure flexibility does not blur risk. For administrators, the focus is on accurate and consistent calculation. For investors, the priority is what is being monitored, how it is being modelled and whether reporting gives a fair view of the structure’s impact.

The firms best placed to navigate the rise of PIK will be those that treat it as a financing choice demanding careful interpretation.
