Private equity GPs earn two primary streams of income: management fees and carried interest. But GPs also earn a third, less visible stream — fees charged directly to portfolio companies for advisory, monitoring, and transaction services. The management fee offset is the mechanism that determines how much of these portfolio company fees flow back to LPs rather than being retained by the GP as additional compensation.
What portfolio company fees are
PE-backed companies pay their GP sponsor a range of fees beyond the equity return on investment. The most common are monitoring fees (annual retainer fees for ongoing strategic and financial oversight, typically 0.5–1% of invested equity or a fixed annual sum), transaction fees (one-time fees paid to the GP at acquisition or exit, often 1–2% of transaction value), and advisory fees (fees for specific strategic projects or M&A advisory within the portfolio company).
These fees are paid by the portfolio company — meaning they come from the company's cash flows, not from LP capital directly. But they still affect LP economics indirectly, because money spent on GP fees is money not available to reduce debt, fund growth, or return to equity holders (including the fund).
The economics: who benefits from the offset
Why the offset matters for net returns
In a large PE fund, portfolio company fees can be substantial. A £5 billion fund with 10 portfolio companies, each paying a £1 million annual monitoring fee, generates £10 million per year in portfolio fees to the GP. With a 50% offset, LPs receive £5 million of benefit. With an 80% offset, they receive £8 million. Over a 5-year holding period, the difference compounds to tens of millions of pounds — meaningful even against a £5 billion fund's absolute returns.
The offset also matters for alignment: a GP who retains all portfolio company fees has a direct financial incentive to charge those fees as aggressively as possible. A GP with a 100% offset has essentially zero incremental benefit from charging portfolio companies — which aligns their incentives more cleanly with LP returns.
The regulatory and disclosure shift
Until the early 2010s, portfolio company fee practices in private equity were opaque and inconsistently disclosed. The SEC's Office of Compliance Inspections and Examinations began examining PE fee practices in 2012, and subsequent enforcement actions revealed widespread fee misclassification and inadequate disclosure at several major firms. The 2015 ILPA Principles and updated 2019 guidance now explicitly address fee disclosure, and the SEC's 2024 Private Fund Adviser Rules require standardised quarterly fee and expense reporting for most registered investment advisers.
LPs evaluating fund terms should now read the entire fee section of the LPA carefully — not just the headline management fee and carry percentages — looking specifically at: what qualifies as a portfolio company fee subject to offset, whether the offset applies to transaction fees as well as monitoring fees, how the offset interacts with the preferred return calculation, and whether fee income received by GP affiliates (rather than the GP entity itself) counts toward the offset threshold.
