When a CLO manager designates a Defaulted Obligation as an LMO, what are the immediate waterfall implications?
TL;DR: Designation of a Defaulted Obligation as a Loss Mitigation Obligation is not a neutral reclassification — at the next determination date it removes the asset from Defaulted Obligation haircut treatment, replaces it with the indenture's LMO carrying value, consumes LMO investment basket capacity, and changes the character of subsequent cash receipts. Whether the OC numerator improves, holds, or deteriorates depends on the specific LMO carrying-value mechanic; designation is not automatically rehabilitative.
Designation is a status change with mechanical consequences, not a remedial action that improves coverage metrics. The asset is taken out of the Defaulted Obligation bucket — where it was carried at the lower of market value and a rating-agency-defined recovery rate — and moved into the LMO bucket, where recent US CLO indentures typically carry the holding at zero, or at cost subject to the aggregate LMO investment cap. For a Defaulted Obligation being haircut at, say, 50–70% of par, that swap usually reduces the OC numerator further on the very first determination date after designation.
CLO portfolio managers face this decision when a workout opportunity emerges and an additional investment is required to participate — a rescue tranche, a debt-for-equity exchange, or new money into a restructuring. The trade-off is not "Defaulted Obligation versus LMO." It is "Defaulted Obligation with limited optionality versus LMO with workout flexibility but harsher carrying treatment and consumption of finite basket capacity." The immediate waterfall implications determine whether the designation can be made at all without tripping a coverage test in the same period.
Why this varies across deals
Four variables drive material differences:
Vintage. Older indentures generally do not contain a fully developed LMO regime; designation may not be available, or only under a narrower "Workout Asset" or "Restructured Obligation" framework with different carrying-value rules. Indentures from around 2019 onward largely follow the LSTA model construct but vary in the carrying-value mechanic.
LMO carrying-value mechanic. Three patterns dominate: carry at zero throughout the holding period; carry at the lower of cost and a rating-agency recovery; or carry at cost subject to the aggregate LMO investment cap, with any excess written down. The first is the most punitive on the OC numerator; the third the most permissive.
LMO investment cap and headroom. The aggregate cap is typically a percentage of the target initial par amount — commonly 2%, 3%, or up to 5%. It measures cost basis or principal balance, not market value. If a Defaulted Obligation is designated at its full par balance, it consumes basket capacity at par even though the OC numerator reflects it at zero.
Interaction with the Interest Diversion Test. Whether cash interest received prior to designation continued to flow into the interest waterfall depends on the indenture's Defaulted Obligation interest treatment. Post-designation, LMO interest receipts follow the LMO proceeds regime, which in most indentures channels interest on surviving loan components to the interest account.
Step-by-step: immediate waterfall implications on designation
Step 1 — Verify eligibility for designation. The manager confirms the obligation satisfies the indenture's LMO definition — typically that the asset relates to an existing portfolio obligor and that the designation is documented prior to or at the time of the relevant action. Designation is not retroactive.
Step 2 — Apply the LMO carrying value at the next determination date. The asset is removed from the Defaulted Obligation calculation and added to the LMO calculation. The OC numerator change equals the LMO carrying value minus the Defaulted Obligation haircut value. In most recent US indentures this difference is negative — LMO carrying value is lower than the Defaulted Obligation recovery-based value.
Step 3 — Consume LMO basket capacity. The principal balance (or cost basis, per the indenture) of the newly designated asset is added to the aggregate LMO investment amount. If aggregate holdings would exceed the cap, designation generally cannot be made — the manager must reduce other LMO exposure first or forgo designation.
Step 4 — Re-character subsequent cash flows under the LMO proceeds regime. From the designation date, receipts are characterised under the LMO proceeds provisions rather than the general Defaulted Obligation proceeds rules. Scheduled principal on a surviving loan enters principal proceeds; interest on a surviving loan enters interest proceeds; equity sale proceeds typically enter principal proceeds; dividends from equity holdings typically enter interest proceeds (subject to manager election in some deals).
Step 5 — Re-run all coverage tests at the next determination date. Every OC test that incorporated the Defaulted Obligation haircut value now reflects the LMO carrying value. Class A/B/C/D OC tests, the Interest Diversion Test (where applicable), and the Reinvestment OC Test are all affected. The Interest Coverage Test is generally not directly affected by the carrying-value change, but the change in interest-proceeds character (Step 4) can flow through to the IC numerator.
Step 6 — Update concentration limits and the trustee report. LMOs are typically excluded from most concentration limits and from the Collateral Quality Tests, in contrast to Defaulted Obligations. The trustee report categorisation changes from the next determination date, and the effective collateral pool used for compliance testing shrinks correspondingly.
Worked example
A CLO holds a $10m senior secured term loan to Borrower Y that became a Defaulted Obligation in month 24, carried at a 60% recovery rate — i.e. $6m in the OC numerator. In month 26, the manager identifies a restructuring requiring a $1.5m new money rescue tranche, and designates the existing $10m loan and the $1.5m rescue tranche as LMOs at funding.
Assume the indenture carries LMOs at zero and the aggregate LMO cap is 3% of $400m target initial par — i.e. $12m. Aggregate LMO holdings prior to designation are $4m.
| Line item | Pre-designation | Post-designation | Delta |
|---|---|---|---|
| OC numerator contribution from this asset | $6.0m (60% recovery) | $0.0m (LMO carried at zero) | −$6.0m |
| LMO basket consumption | $4.0m | $15.5m ($4.0m + $10.0m + $1.5m) | +$11.5m |
| LMO basket headroom remaining | $8.0m | −$3.5m: breach (see note) | n/a |
| Defaulted Obligation par balance | $10.0m | $0.0m | −$10.0m |
Note on the basket breach. At a 3% cap, the designation as drawn would exceed the LMO basket by $3.5m. The manager must reduce other LMO exposure first, reduce the new-money component, or forgo designation — the most common reason designation is operationally blocked even when economically attractive.
Net result. Designation, if completed without the basket constraint, would reduce the OC numerator by $6.0m on the next determination date. Whether that trips an OC test depends on existing headroom. The trade-off is the workout flexibility LMO status confers — the ability to receive equity, fund additional rescue tranches, and avoid a forced Credit Risk Sale of the original Defaulted Obligation at a depressed price.

Why generic AI gets this wrong
The most common failure mode is defined-term scope confusion. Generic models treat LMO designation as a reclassification that improves portfolio metrics — analogising it to a Credit Improved Obligation or a return to performing status. The error reflects the training corpus: investor-facing summaries describe LMOs as a flexibility-enhancing feature without modelling the carrying-value mechanic. In practice, in most recent US indentures, designation reduces the OC numerator on the next determination date because LMO carrying value is more conservative than Defaulted Obligation recovery-based haircuts. A second, related failure is conflating the LMO investment cap (measured at cost or par) with the OC carrying value (zero in many deals) — two different measurements governing two different constraints. Semeris extracts the LMO carrying-value mechanic, the aggregate cap, and the designation eligibility conditions as discrete datapoints, so the immediate waterfall impact of any contemplated designation can be modelled against the specific indenture rather than a generic template.
