Evergreen Fund Structures in PE: The Impact of Perpetual-Life Funds on Buyout Strategies

The shift is structural, not cyclical. As of Q1 2026, perpetual-life funds — open-ended vehicles with no fixed 10-year liquidation date — now account for an estimated 28% of dry powder held by the top 50 private equity firms globally, according to Preqin’s 2025 annual report. This is not a niche product from a handful of alternative asset managers. Blackstone’s non-traded BDC and perpetual infrastructure funds alone held USD 72.4 billion in assets under management as of 31 December 2025, per its Q4 2025 earnings release. The implications for Hong Kong’s buyout market are direct. When a general partner (GP) manages a vehicle that does not need to return capital within a fixed term, the calculus for every deal changes: holding periods can extend beyond a decade, dividend recapitalizations become a primary return mechanism rather than an exit, and the sponsor’s alignment with portfolio company management shifts from a five-year timeline to an indefinite partnership. For CFOs and company secretaries of Hong Kong-listed targets, and for the law firms structuring these acquisitions under the Securities and Futures Ordinance (Cap. 571), understanding the mechanics of these vehicles is no longer optional — it is a prerequisite for advising on any mid-to-large-cap buyout.

The Mechanics of Perpetual-Life Fund Structures

Open-Ended vs. Closed-Ended: The Liquidity Distinction

A traditional buyout fund is a closed-ended limited partnership with a defined life, typically 10 years with two one-year extensions. Investors commit capital at inception, receive distributions from realisations, and the fund dissolves. A perpetual-life fund, by contrast, operates as an open-ended vehicle — often structured as a non-traded REIT, a BDC, or a Luxembourg RAIF — where investors can subscribe and redeem at net asset value (NAV) on a periodic basis, usually quarterly.

The key regulatory distinction in Hong Kong lies in how these vehicles are classified under the SFC’s Code on Real Estate Investment Trusts and the Securities and Futures (Recognised Collective Investment Schemes) Rules (Cap. 571). A perpetual-life fund that is listed on the HKEX must comply with the Listing Rules for REITs (Chapter 5 of the Main Board Listing Rules), which impose a maximum gearing limit of 50% of gross asset value. Non-listed perpetual vehicles, however, face no such statutory cap, allowing leverage ratios that can exceed 70% in certain infrastructure and credit strategies.

The GP’s Incentive Structure

The compensation model for perpetual-life funds differs materially from traditional closed-end funds. Management fees are calculated on NAV rather than committed capital, and the base fee is typically lower — 1.0% to 1.25% per annum versus 1.5% to 2.0% — but the carried interest hurdle is also lower, often 5% to 6% rather than the standard 8%. More critically, the GP earns carried interest on a rolling basis, calculated on annual realised gains rather than on a fund-level waterfall at liquidation.

This creates a behavioural shift. In a traditional fund, the GP has a strong incentive to exit investments within years 5 to 7 of the fund life to crystallise carry and return capital for a successor fund. In a perpetual vehicle, the GP can hold assets indefinitely, collecting management fees on the growing NAV while earning carry on partial realisations — such as dividend recaps or minority stake sales — without triggering a full exit. For buyout targets in Hong Kong, this means a sponsor with a perpetual-life fund is far more likely to pursue a long-term operational improvement strategy rather than a financial engineering play.

Implications for Buyout Strategy and Deal Structuring

Extended Holding Periods and the Impact on Valuation

The most direct consequence of perpetual capital is the lengthening of the average holding period for portfolio companies. McKinsey’s 2025 Private Markets Review found that assets held in perpetual-life vehicles had a median holding period of 11.3 years, compared to 5.8 years for traditional buyout funds. In Hong Kong, where family-owned manufacturing and logistics businesses often require multi-generational turnaround timelines, this structural patience aligns with the operational reality of the target.

For valuation purposes, the longer horizon changes the discount rate applied in DCF models. A traditional buyout fund targeting a 20% IRR over five years requires aggressive exit multiples. A perpetual fund targeting a 12% to 14% IRR over 10-plus years can accept lower entry multiples and higher initial leverage, because the compounding effect of operational improvements over a decade outweighs the drag from debt service. This dynamic has been observed in the acquisition of Hong Kong-based logistics assets by Blackstone’s perpetual infrastructure fund, where the initial leverage ratio was 65% — above the typical 50-55% for traditional buyout funds — but the projected exit multiple was 12x EBITDA versus the 15x typically required for a five-year hold.

Dividend Recaps as a Primary Return Mechanism

When a fund cannot rely on a full trade sale or IPO within a fixed term, dividend recapitalisation becomes a core return tool. In a perpetual-life vehicle, the GP can refinance a portfolio company’s debt to distribute cash to the fund, generating current yield for investors without selling the asset. This is not new — dividend recaps have been a feature of mid-market buyouts for decades — but the scale and frequency shift dramatically.

Data from S&P LCD shows that dividend recaps in Hong Kong and China buyout transactions accounted for 34% of total distributions from perpetual-life funds in 2025, versus 11% for traditional closed-end funds. The HKMA’s 2025 Supervisory Policy Manual on leveraged lending (CM-1) does not prohibit dividend recaps, but it does require banks to maintain a minimum debt service coverage ratio of 1.25x post-recap. For a Hong Kong-incorporated portfolio company, this means the CFO must model the impact of the recap on the company’s stand-alone credit profile, not just the fund’s return metrics.

Regulatory Arbitrage in Jurisdiction Selection

Perpetual-life funds are not domiciled uniformly. The vehicle’s legal structure determines the tax treatment of distributions, the regulatory oversight of leverage, and the ease of investor redemption. In Hong Kong, the most common structures for perpetual-life funds targeting Asian buyouts are:

• Cayman Islands exempted limited partnerships with a master-feeder structure into a Hong Kong operating company. This avoids Hong Kong profits tax on the fund level, provided the fund does not carry on a trade or business in Hong Kong under Section 14 of the Inland Revenue Ordinance (Cap. 112).
• Luxembourg RAIFs (Reserved Alternative Investment Funds) for European institutional investors, which benefit from the AIFMD passport but require a Hong Kong SFC Type 9 licence for asset management activities.
• Singapore VCCs (Variable Capital Companies) , which offer tax transparency and redemption flexibility, though the fund must appoint a Hong Kong-licensed sponsor for any acquisition of a Hong Kong-incorporated target under the Takeovers Code.

The choice of jurisdiction directly affects the speed and cost of execution. A Cayman fund acquiring a Hong Kong company can complete the transaction in 8 to 12 weeks under the standard HKEX disclosure regime, while a Luxembourg RAIF requires an additional 4 to 6 weeks for AIFMD compliance filings.

The Hong Kong Regulatory Response

SFC Guidance on Open-Ended Fund Structures

The SFC has not issued a dedicated circular on perpetual-life private equity funds, but its 2024 Guidance Note on the Authorisation of Open-Ended Fund Companies (OFCs) under the Securities and Futures (Open-Ended Fund Companies) Rules (Cap. 571AQ) provides the relevant framework. An OFC can be structured as a perpetual vehicle, but the SFC requires that the fund’s prospectus explicitly disclose the redemption frequency, the valuation methodology for illiquid assets, and the circumstances under which redemptions may be suspended.

For buyout funds holding Hong Kong portfolio companies, the valuation of unlisted equity is the critical issue. The SFC’s 2023 Code of Conduct for Persons Licensed by or Registered with the SFC requires that all valuations be performed by an independent valuer at least annually, with the valuation methodology consistent with the International Private Equity and Venture Capital Valuation (IPEV) Guidelines. In practice, this means a perpetual-life fund holding a Hong Kong manufacturing company must obtain a valuation report from a qualified firm such as KPMG or Deloitte every 12 months, with the cost typically borne by the portfolio company.

HKMA’s Stance on Leveraged Lending to Perpetual Vehicles

The HKMA’s Supervisory Policy Manual on leveraged lending (CM-1, revised January 2025) explicitly addresses the risk of “evergreen” loan facilities extended to perpetual-life funds. The guidance requires that any loan with a tenor exceeding seven years be classified as a “long-term leveraged exposure” and be subject to a minimum risk weight of 150% under the Basel III framework for Hong Kong-incorporated banks.

This has a direct impact on the cost of debt for a perpetual-life fund acquiring a Hong Kong target. A 10-year acquisition facility will carry a risk-weighted capital charge approximately 50 bps higher than a five-year facility, which the bank will pass through to the borrower. For a deal size of HKD 2 billion with 60% leverage, this translates to an additional HKD 6 million per annum in interest expense — a material drag on the fund’s net IRR.

Case Studies in Hong Kong’s Market

The Long-Term Hold: A Family-Owned Logistics Platform

In 2022, a global infrastructure manager acquired a Hong Kong-based cold chain logistics operator through its perpetual-life infrastructure fund. The purchase price was HKD 3.8 billion, financed with 65% debt from a syndicate of three Hong Kong-licensed banks. The sponsor did not exit in 2025. Instead, it completed two dividend recaps — in 2023 and 2025 — totalling HKD 1.2 billion, returning 32% of the initial equity to investors while retaining full ownership.

The operational strategy was built around capital expenditure. The fund invested HKD 450 million in automation and warehouse management systems, reducing the company’s labour cost from 38% of revenue to 24% over three years. The EBITDA margin expanded from 14.2% in 2022 to 19.8% in 2025. A traditional buyout fund with a five-year horizon would have prioritised a 2025 exit, likely through a trade sale to a Chinese logistics conglomerate at 10x EBITDA. The perpetual fund’s decision to hold reflects a different risk-return profile: the internal rate of return on the retained equity, including the dividend recaps, is 13.7% — below the typical 20% target for closed-end funds, but with lower reinvestment risk and no pressure to deploy capital into a frothy market.

The Failed Exit: Lessons in Redemption Risk

Not all perpetual structures succeed. In 2024, a Hong Kong-listed BDC managed by a regional sponsor faced a redemption wave after its NAV declined by 18% following a write-down on a Macau gaming-related investment. The BDC’s prospectus, filed under the SFC’s Code on Real Estate Investment Trusts, permitted quarterly redemptions up to 5% of NAV. When redemption requests exceeded 12% in a single quarter, the manager suspended redemptions for 90 days, triggering a 35% decline in the BDC’s secondary market price.

The incident highlighted a structural risk: perpetual-life funds are not immune to liquidity mismatches. The SFC’s 2024 consultation paper on open-ended fund liquidity management proposed mandatory redemption gates and side-pocketing provisions for any fund holding more than 20% of its NAV in illiquid assets. For buyout funds, where the entire portfolio is illiquid by definition, this rule effectively limits the redemption frequency to semi-annual or annual, not quarterly.

Actionable Takeaways

1. Sponsors using perpetual-life vehicles must model dividend recaps as the primary return mechanism for Hong Kong buyouts, not trade sales or IPOs, and incorporate the HKMA’s 1.25x debt service coverage ratio into the portfolio company’s financial projections.
2. CFOs of Hong Kong-incorporated portfolio companies held by perpetual funds should negotiate independent valuation clauses in the shareholders’ agreement, referencing the IPEV Guidelines, to avoid disputes over NAV-based management fees.
3. The choice of fund domicile directly affects execution speed — a Cayman vehicle can close a Hong Kong acquisition in 8 to 12 weeks, while a Luxembourg RAIF adds 4 to 6 weeks for AIFMD compliance.
4. Leverage costs are structurally higher for perpetual vehicles due to the HKMA’s 150% risk weighting on loans exceeding seven years, adding approximately HKD 6 million per annum in interest on a HKD 2 billion facility.
5. Redemption risk is the single greatest structural vulnerability of perpetual-life buyout funds — any fund holding more than 20% of its NAV in illiquid assets should expect the SFC to mandate semi-annual redemption gates, limiting investor liquidity.
