Before you start
Internal and external BDC management: follow the expense contract, NII and distribution coverage: match the income, denominator and period, PIK income: distinguish the contract, the accounting and the cash
- Calculate a transparent hypothetical hurdle and catch-up schedule.
- Separate pre-fee income, fee expense and income after the fee.
- Identify why accounting accruals and contractual fees paid may differ.
Read the specific contract, not an industry slogan
An income incentive fee can use a defined pre-fee income base, a hurdle, a catch-up and further participation above the catch-up band. Some agreements include additional limitations, lookbacks or total-return features. Rates, bases and treatment of PIK or waived amounts differ. A fee described as a percentage of income is not necessarily that percentage of every dollar above a hurdle. Start with the actual agreement for the relevant period and reconstruct its intervals before applying a sensitivity. The deliberately simplified schedule below is an original teaching example, not a description of any named issuer's terms.
Synthetic: the hurdle is not merely a deductible
Assume equity of 100, a quarterly hurdle of 1.5% or 1.5, a 20% participation rate and a full catch-up. The catch-up ends at 1.5 / (1 − 20%) = 1.875 of pre-fee income. At income 1.4, the fee is zero. At 1.6, the assumed fee is 1.6 − 1.5 = 0.1, leaving 1.5. At 2.0, the fee is 0.375 for the catch-up plus 20% × (2.0 − 1.875) = 0.025, totaling 0.4 and leaving 1.6. No base fees, losses, waivers, lookbacks or capital-gains fee are included.
A catch-up can change who keeps the next dollar
In a full catch-up band, the adviser may receive all of the defined income above the hurdle until its share reaches the contractual participation rate. The shareholder result can consequently remain flat through that interval even as pre-fee income rises. Above the catch-up band, the ordinary participation rate applies to incremental income under the assumed schedule. This is a marginal calculation, so retain the lower intervals instead of repeatedly applying one rate to the whole amount. State whether the hurdle is quarterly or annual and which net-asset value determines its dollar amount.
Income and capital-gains fees are separate bridges
A capital-gains incentive calculation can depend on cumulative realized results, unrealized depreciation and amounts already paid, according to the contract. Accounting expense or accrual can differ from the fee currently payable. A mark reversing in the next quarter may therefore affect accrued expense differently from cash payment. Do not subtract an estimate of a future fee on top of a reported expense without reconciling what is already recognized. Also distinguish base management fees from incentive fees: both may appear within NII, but their bases and sensitivities need not respond to the same inputs.
PIK sensitivities should state what happens to fees
A simple NII-minus-PIK illustration intentionally leaves other items unchanged. A contract-sensitive alternative might adjust the income fee when the relevant pre-fee base changes, but that is a different model requiring the fee agreement. Show the reported result, the simple sensitivity and the contract-based alternative in separate columns. Do not automatically assume that a fee on previously recognized noncash income will be refunded after a later loss; examine actual provisions. Likewise, a hypothetical exclusion from your research model does not change the issuer's contract or prove misconduct in its accounting.
Test your reasoning
Under only the synthetic schedule, what fee and post-fee income result from pre-fee income of 1.8?
Reveal the worked answer
The amount is inside the full catch-up band. Fee is 1.8 − 1.5 = 0.3 and post-fee income remains 1.5. Do not apply this toy schedule to an issuer without its actual agreement.
A common mistake
Charging 20% only on income above the hurdle when the actual contract includes a full catch-up, or adjusting fees twice.
What to check in the disclosures
- Read the agreement effective for the period.
- Translate rates into matching-period dollar thresholds.
- Separate expense accrued, amounts payable and cash paid.
- Identify PIK treatment, waivers, limitations and prior fees.
