Co-mingling risk

In a securitised debt deal, a servicer collects loan repayments from thousands of individual borrowers and passes that money on to investors. That handover is not always instant.

Some of what borrowers pay comes in as cash, and it takes time to bank it and route it into a dedicated collection account. In that gap, the money is sitting inside the servicer's own operations, not yet segregated for investors.

If the servicer runs into financial trouble during exactly that window — before the funds are moved to the collection account — investors can lose money that was, in substance, already theirs. That is co-mingling risk, and it is managed mainly by choosing servicers who are themselves highly rated and financially sound.

Chapter 10 describes the mechanism: servicers normally deposit collections into the collection account, but there can be a time gap between collecting from obligors and depositing into that account, especially where collections arrive as cash. During that interim period, collections may not be segregated from the servicer's other funds. If the servicer fails to remit those funds, investors are exposed to potential loss.

The mitigant the workbook names is structural, not contractual: due care is taken to ensure the servicer carries the highest credit rating on a standalone basis, which minimises — though does not eliminate — co-mingling risk. This sits alongside other securitised-debt risk factors in the same chapter, including the risk that a court could treat the investor's agent's recourse to receivables as personal rather than held in trust.

Illustrative — the workbook describes the risk, not a worked collection figure.

A pool of car-loan receivables is securitised, with monthly EMIs of roughly Rs 8 crore collected across thousands of borrowers, a portion of it in cash at branch counters. The servicer typically deposits collections into the dedicated collection account within 2 business days.

On a particular month-end, the servicer is holding Rs 1.2 crore of collected-but-not-yet-deposited cash when it is placed under a regulatory freeze due to unrelated financial stress. That Rs 1.2 crore, though legally meant for investors, sits inside the servicer's frozen accounts — exactly the loss co-mingling risk describes. Had the servicer carried the highest standalone credit rating, as the workbook's mitigant recommends, this scenario would have been considered far less likely.

Chapter 10 (Risk, Return and Performance of Funds), under "Risks Associated with Investments in Securitised Debt," names co-mingling risk directly, alongside bankruptcy-remoteness risk for the investor's agent. Expect a question on what specifically causes co-mingling risk (the timing gap between collection and deposit) and how it is mitigated (servicer credit quality).

• This is not the same "co-mingling" as mixing an NPO's unutilised issue funds with its other money — that is a separate rule in a different context. Here, co-mingling risk is specific to a securitisation servicer's cash-handling gap.
• The risk arises from timing, not from dishonesty. Even an honest servicer creates the exposure simply because deposits are not instantaneous.
• The mitigant is the servicer's own credit rating, not a guarantee — co-mingling risk is reduced, not removed, by choosing a well-rated servicer.
