Treat an add-back as a claim to investigate. Ask what happened, whether the cost repeats, what evidence supports the amount and whether cash still has to be paid. The label “one-time” does not resolve those questions.
Keep the earnings views separate
Reported EBITDA is the supplied starting measure. Management-adjusted EBITDA reflects proposed adjustments. Underwritten EBITDA is the economic view used in your analysis. Covenant EBITDA is defined by the agreement and may differ from all three. EBITDA itself is not a standard GAAP line item; reconcile it to the underlying statements.
An original adjustment case
A fictional company reports $15 million of EBITDA. Management adds $2 million of expected savings, $0.5 million for a completed legal settlement and $1 million of recurring customer-acquisition spending.
Assume the settlement is fully paid and demonstrably nonrecurring, the savings are unsupported and acquisition spending is needed to maintain the business. Under these stipulated facts, an underwriting case using $15.5 million is defensible. Management's view is $18.5 million.
| Measure | EBITDA | Leverage on $62m debt |
|---|---|---|
| Management adjusted | $18.5m | 3.35x |
| Underwritten case | $15.5m | 4.00x |
The difference changes apparent leverage materially. It does not by itself establish a contractual breach; that requires the actual covenant definition and threshold.
Build an adjustment register
Record the source, amount, period, evidence, economic treatment and remaining cash cost. Expected savings need implementation timing and support. Owner compensation requires a realistic replacement cost. Repeated integration costs may recur if acquisitions are a continuing strategy.
If you accept a historical noncash or nonrecurring adjustment, trace the cash-flow bridge so the same benefit is not counted twice. An adjustment that improves the earnings denominator can coexist with a future cash payment.
Know the limits of a source
The SEC's non-GAAP interpretations discuss potentially misleading exclusions of normal recurring operating costs in public reporting. They provide useful context for scrutiny, but do not define a private loan's covenant EBITDA or replace legal review.
Continue with the cash-flow model. The underwriting workbook connects adjustments to repayment, stress, covenants and a lending memo. For broader oral preparation, retain the existing private-credit interview questions as your starting list.
