A parallel fund is a separate investment vehicle that invests alongside a main fund on a pro-rata basis, deal by deal. Unlike a feeder fund that channels capital into a master fund, a parallel fund holds its own direct interest in each portfolio company. The two structures serve similar purposes (accommodating different investor types) but work differently under the hood.
Why Parallel Funds Exist
The core problem is the same one that drives master-feeder structures: different investors have different tax, regulatory, and legal requirements. A US tax-exempt institution, a European sovereign wealth fund, and a group of US taxable individuals often cannot invest through the same entity without creating problems for at least one group.
In private equity and venture capital, parallel funds are the preferred solution. The reason is direct ownership. When a limited partner invests through a parallel vehicle, they hold a direct (albeit proportional) interest in the underlying portfolio companies. This matters for regulatory reporting, ERISA compliance, tax treaty benefits, and situations where an LP’s mandate requires direct exposure to the asset class rather than indirect exposure through another fund.
How Allocation Works
The general partner commits to a consistent allocation policy across all parallel vehicles. Typically, each fund participates in every deal on a pro-rata basis determined by relative committed capital. If the main fund represents 75% of aggregate commitments and the parallel fund represents 25%, each deal is split 75/25.
This policy is documented in each vehicle’s limited partnership agreement and cannot be selectively applied. The GP cannot cherry-pick deals for one vehicle over another. Consistent pro-rata allocation is the foundation of the structure’s integrity, and any deviation creates serious fiduciary and regulatory risk.
Parallel vs. Master-Feeder
The distinction matters for investors and managers alike. In a master-feeder, there is one pool of assets held by one entity. In a parallel structure, each vehicle is a separate owner of its proportional slice. This creates more complexity at the deal level (each portfolio company’s cap table includes multiple fund entities) but gives investors cleaner legal ownership.
Parallel structures also avoid the UBTI issues that sometimes arise in master-feeder arrangements, which is why US tax-exempt investors frequently prefer them. The tradeoff is higher administrative cost. Each parallel vehicle requires its own audit, its own tax filings, its own capital account tracking, and its own fund administration.
Practical Considerations
Standing up a parallel fund increases fund formation complexity and cost. You need separate legal counsel review, separate subscription documents, and a clearly documented allocation policy. Most managers introduce a parallel vehicle only when they have a meaningful cohort of investors who cannot participate in the main fund’s structure.
The fund domicile of the parallel vehicle depends on the investor base it serves. A common configuration is a Delaware LP as the main fund (for US taxable investors) and a Cayman or Luxembourg parallel fund (for non-US and US tax-exempt investors). The GP manages both vehicles under a single investment strategy, making allocation decisions once and executing them across both entities simultaneously.
Frequently Asked Questions
What is the difference between a parallel fund and a feeder fund?
A feeder fund invests its capital into a master fund, which holds all assets centrally. A parallel fund invests directly into portfolio companies alongside the main fund, holding its own pro-rata share of each asset. Parallel fund investors are direct co-owners of the underlying investments, while feeder fund investors have indirect exposure through the master entity.
How are investments allocated between parallel funds?
Investments are allocated pro-rata based on each parallel vehicle's committed capital relative to total aggregate commitments. If the main fund has $400 million in commitments and the parallel fund has $100 million, the parallel fund takes 20% of each deal. The GP's allocation policy is documented in each fund's LPA and must be applied consistently.
Why are parallel funds more common in private equity than hedge funds?
Private equity investors often require direct ownership of underlying portfolio companies for regulatory, tax, or governance reasons. A parallel structure provides this because each vehicle holds its own interest in the asset. Hedge funds, which trade liquid securities and need operational speed, typically prefer master-feeder structures where a single entity executes all trades.
