Management fee step-downs and how they reshape GP economics

The management fee is the periodic payment to the manager for managing the fund. The ILPA model makes it payable from the date the fund acquires its first permanent portfolio investment to the earlier of the last day of the initial term and the appointment of a liquidator, in quarterly instalments in advance. Two details in that sentence are frequently negotiated and rarely modelled: the commencement trigger keyed to the first permanent investment rather than to the closing, and payment in advance rather than in arrears.

The most common initial fee level is two per cent, though the majority of funds give concessions after the investment period — which is the fact that makes the step-down the interesting term rather than the headline rate. Limited partners bear the fee through capital contributions, and the ILPA Reporting Template carries management fees as a standardised capital account line precisely so that the direct cost of participating is visible.

The base the rate applies to is a separate term from the rate. Four canonical constructions are documented: a constant percentage of committed capital; a decreasing percentage of committed capital after the investment period; a constant rate with the base changing from committed capital to net invested capital; and both a decreasing percentage and a base change. The measures underneath them are defined precisely — lifetime fees, investment capital, invested capital, net invested capital meaning invested capital less the cost basis of exited investments, contributed capital and net contributed capital — and using the wrong one is the most common modelling error in this area.

During the investment period the commitment base is the ILPA model's construction, and the rationale is straightforward: the primary determinant of the manager's workload during that period is the search for investments, which is driven by total commitments rather than by the amount actually deployed.

The three mechanisms are enumerated in the sourced literature and they should be read out of a draft separately. First, a step change in the percentage rate at the end of the investment period. Second, an annual reduction in the rate thereafter. Third, changing the asset base from commitments to the cost basis of the unrealised portfolio. A single agreement can carry one, two or all three, and the phrase steps down after the investment period tells you nothing about which.

ILPA's position on the base is specific: after the investment period the fee should step down to a percentage of unrealised cost — that is, capital contributions funding the acquisition cost of portfolio investments, less the acquisition cost of investments realised, written off or permanently written down. That formulation is doing more work than a rate cut, because it shrinks automatically as the portfolio is realised rather than on a schedule.

The worked exemplar for the rate mechanism is a two per cent fee during a five-year investment period falling by twenty-five basis points per year for the next five years. It is a useful reference point and it is one drafting exemplar rather than a market convention, so it belongs in a model as an input rather than as an assumption.

A bifurcated construction sits between the two bases. ILPA suggests that general partners and limited partners may wish to consider a bifurcated fee during the investment period reflecting an appropriate blended percentage of capital committed and invested, and that experienced general partners should consider basing initial fees for a follow-on fund on invested rather than committed capital. The second half of that is a live ask for any manager past a first fund.

The trigger is a term in its own right. The ILPA model runs the commitment-based fee until termination of the commitment period or, if earlier, when a management fee begins to accrue in respect of a successor fund. That successor-fund cutover is the clause that prevents a manager charging a full commitment-based fee on two funds at once, and its absence is worth checking for before anything else in the fee section.

ILPA's position on term extensions is stricter than most drafts: no fees should be charged after the original term of the fund has ended, and if circumstances warrant a fee to incentivise liquidation the general partner should seek an amendment rather than rely on the existing document. During an extension no fees should be charged unless and until limited partners agree on the facts and circumstances of maximising value and liquidating the remaining assets, with extensions permitted only in one-year increments, limited to two, approved first by the advisory committee and then by a super-majority of limited partners.

Individual fee arrangements interact with the step-down in a way that is easy to model wrongly. Where a general partner has agreed a fee cap for a single investor or group, ILPA requires any amount above the cap to be absorbed by the general partner and not included in calculating the management fee as a percentage of assets allocated to the remaining investors. A model that spreads the shortfall across the other limited partners has the incidence backwards.

One piece of vocabulary in this area has no definition behind it. A period during which no fee accrues is described in the market with a phrase that appears in no authoritative source; the nearest verified analogues are the ILPA model's commencement trigger, under which the fee runs only from the first permanent portfolio investment, and the extension no-fee rule above. Those are the mechanics to publish.

Fees are not the residual part of a manager's economics. About sixty per cent of a manager's expected revenue comes from fixed-revenue components rather than from carried interest, which reframes the step-down from a housekeeping term into one of the two variables that set the firm's revenue. A manager modelling its own business off carry alone is modelling the minority of its expected income.

The step-down also interacts with the carry basis, and this is the connection most treatments miss. Where the carry basis is committed capital, lifetime fees do not enter the profit computation; where it is investment capital, they do. Switching from committed to investment capital is worth the carry level multiplied by lifetime fees — so a manager conceding a larger step-down and simultaneously conceding the carry basis is conceding twice on the same dollars.

For the aggregate picture, the sourced framing is ILPA's: the Reporting Template seeks to provide insight, in a standardised format, into the totality of fees and expenses limited partners incur, and ILPA's principles require general partners to provide a fee model guiding how management fees will be calculated over the fund's life, preferably covering fees, expenses and carried interest together. Asking for that model is a better move than asking for a single summary ratio, and the ratio that circulates for this purpose is a registered-fund concept with no authoritative application to closed-end private funds.
