Sub participation
A sub-participation (also written sub participation) is a contractual arrangement under which an existing lender (the grantor) passes the economic risk and return of all or part of a loan to a third-party participant, while remaining the lender of record to the borrower. The borrower is not a party to the participation agreement and usually has no direct claim against, or obligation to, the participant.
How sub-participation is used on PF and EF desks
On project finance and export finance desks, sub-participation is used when a bank needs to reduce exposure, free capacity, or bring in a relationship bank without changing the lender register. It is common after primary syndication when transfer restrictions, borrower consent requirements, or operational constraints make novation or assignment impractical.
The ACT Borrower's Guide to LMA investment grade documentation distinguishes three secondary methods: novation (purchaser assumes rights and obligations and becomes a contractual lender), assignment (rights transfer, with a direct claim against the borrower), and sub-participation (a back-to-back contract between seller and purchaser with no direct borrower relationship). Loan Market Association guides on syndicated loans and secondary trading likewise treat transfer of participations as a core market mechanic alongside primary documentation.
Multilateral B Loan structures illustrate a related participation model: IFC remains sole contractual lender while selling participations in a B Loan tranche to eligible private lenders under separate participation agreements.
Mechanics of a funded sub-participation
In a funded sub-participation, the participant advances funds to the grantor corresponding to the participated amount. The grantor remains responsible for funding the borrower and for receiving borrower payments. The grantor remits to the participant only what it actually receives (or is deemed to receive under the participation terms) for that share. Voting and waiver rights ordinarily stay with the lender of record unless the parties agree elevation, consultation, or voting-instruction mechanics.
Because the participant is not a finance party under the facility agreement, borrower consent is often not required under traditional LMA investment grade transfer clauses, which focus on changes to the lender of record. Some borrowers negotiate consent or voting-control protections for behind-the-scenes risk transfers. The facility agent does not usually update the lender register for a pure sub-participation.
Distinctions from risk participation and transfer
A funded sub-participation moves both funding and credit risk. A risk participation is typically unfunded: the participant reimburses the grantor if the borrower fails to pay, without advancing the loan principal up front. Novation or assignment changes the lender of record and usually requires agent processing and, often, borrower consent. Sub-participation preserves confidentiality of the economic buyer from the borrower's perspective, but leaves the participant exposed to grantor credit risk as well as borrower performance.
