Sidecar Fund
A parallel vehicle that invests alongside a main fund on specific deals, typically to allow certain LPs or platforms to top up exposure to selected opportunities.
Sidecar Fund explained
A sidecar is a vehicle that invests alongside a main fund, usually to accommodate specific investors or a particular deal type. It has its own investors and terms while following the main fund's decisions. The governance question is allocation: how opportunities are split between the two, and how that split is evidenced.
How it works in practice
- An allocation policy governs the split and is applied consistently.
- Each allocation decision is recorded with its rationale.
- The sidecar carries its own register, accounting and reporting line.
Common mistake
Allocating case by case without a written policy, which creates conflict exposure with the main fund's investors.
Why it matters in private capital
Sidecar Fund sits inside a chain of decisions that runs from sourcing through diligence, investment committee, portfolio monitoring and LP reporting. When each stage lives in a different tool, the evidence behind the decision is rebuilt at every handover. Keeping the concept on one record is what makes the fund able to explain, not just report, what it did.
