Obligor Concentration
Definition
Obligor concentration measures how much exposure a credit pool has to a single party that is expected to make payments. The obligor may be a borrower, customer, tenant, account debtor, merchant, insurer, distributor, or other payment source depending on the asset class.
Why it matters
Private credit losses are often driven by who actually pays. A pool can appear diversified by number of invoices, leases, or advances while depending economically on a small number of payers. Obligor concentration helps investors find hidden single-name risk.
Common misconceptions
- •Borrower count and obligor count are not always the same.
- •Many invoices to one customer are not diversified cash flow.
- •Strong collateral does not fully offset concentration if the collateral value also depends on the same obligor relationship.
Technical details
How it is measured
The simplest measure is largest obligor balance divided by total collateral or total note exposure. More robust reporting shows top 5, top 10, and sector-level obligor exposure.
For receivables, the obligor is the account debtor who owes payment. For litigation or medical receivables, it may be an insurer or settlement counterparty. For real estate credit, it may be a tenant, sponsor, or takeout buyer.
Why it changes recoveries
If the largest obligor delays payment, disputes invoices, files bankruptcy, or offsets claims, multiple assets can deteriorate simultaneously.
Concentrated pools need lower advance rates, stronger reserves, better reporting, or stronger payer credit quality to justify similar leverage.
Diligence questions
Who are the top obligors, and are they disclosed by name or anonymized?
Are obligor caps calculated before or after ineligible collateral?
Has the platform experienced prior losses tied to obligor disputes rather than borrower defaults?
