The same underlying credit exposure can be packaged and accessed in several different ways, and the structure chosen changes who bears risk, how liquid the position is, and how returns are shared between the manager and its investors. Understanding these structures matters as much as understanding the strategy itself, since two funds pursuing the identical distressed debt opportunity can produce very different outcomes for their investors purely based on how the deal is structured.
This page picks up directly from the strategy types these structures support, which cover what opportunistic managers invest in. Here, the focus shifts to how those investments are packaged and where they sit on the risk-return spectrum, independent of the specific strategy or asset class involved.
A bilateral deal is negotiated directly between a single lender and a single borrower, without a syndicate of co-lenders. This structure gives the lender full control over terms and covenants and is common in rescue financing and control-oriented distressed situations where speed and confidentiality matter more than broad distribution.
Syndicated structures involve multiple lenders participating in a single loan or facility, typically arranged by a lead bank or credit fund. This spreads exposure across several capital providers and is more common in larger opportunistic direct lending transactions where a single manager may not want, or be able, to hold the full facility alone.
A CLO vehicle pools a portfolio of leveraged loans and issues tranched securities against that pool, with each tranche carrying a different priority of payment and, correspondingly, a different risk-return profile. CLOs are the primary structural vehicle for structured credit strategies and allow managers to access leveraged loan exposure at scale without originating each underlying loan individually.
Closed-end funds raise a fixed pool of capital with a defined investment period and maturity, matching the illiquid, multi-year nature of many distressed and special situations positions. Evergreen fund structures, by contrast, have no fixed end date and periodically accept new capital and honor redemptions, offering more flexibility for both managers and investors at the cost of some illiquidity mismatch risk.
Co-investment platforms allow institutional allocators to invest directly alongside a manager's main fund in specific transactions, typically on more favorable fee terms. These platforms have grown as large allocators seek greater control over which specific opportunities they are exposed to, rather than accepting blind-pool fund commitments alone.
Within any given deal, structure interacts with a second dimension: where a position sits in the capital stack. Three broad risk-return tiers apply across opportunistic credit and structured finance.
Senior secured opportunistic positions and bilateral private deals pair naturally, since a direct negotiation gives the lender the leverage to insist on strong security. CLO vehicles inherently span all three risk-return tiers within a single structure, since that is the entire premise of tranching: different investors choose their preferred point on the risk-return spectrum within one pooled vehicle.
An allocator's choice of structure should follow from its risk tolerance and liquidity needs, not the other way around. An institution seeking senior, capital-preservation-oriented exposure gravitates toward bilateral senior secured deals or the senior tranches of CLOs. An investor comfortable with illiquidity and control-oriented risk in exchange for higher return potential is a more natural fit for closed-end fund structures targeting equity-like distressed positions. Co-investment platforms sit somewhat orthogonally to this spectrum, since they are more about control over specific transaction selection than about a particular risk tier.
The structure available for a given opportunity is often dictated by the borrower's situation and the legal jurisdiction governing the restructuring. A US Chapter 11 process, a European restructuring regime and an offshore structured finance jurisdiction each impose different constraints on how quickly a deal can be structured and which structures are enforceable.
