Document III
External Supports
External supports bring a promise from outside the deal. Where internal supports rearrange the deal’s own assets, an external support adds a new balance sheet: a bank, an insurer, a parent company, or an independent institution holding cash. The holder gains a second obligor, and with it a second condition to watch, because a support is only as good as the party providing it on the day it is needed.
Letters of credit
A standby letter of credit is a bank’s undertaking to pay when the borrower does not, up to a stated amount, on presentation of the documents the letter names. It is drawn only on failure; in the ordinary course it sits unused behind the deal. Letters carry expiry dates, and a letter that expires before the debt matures must be renewed or replaced, which makes the renewal calendar part of the credit.
At a glance
- Protection: a bank pays, up to the stated amount, when the borrower fails.
- Watch: the bank’s own condition and the letter’s expiry and renewal terms.
- Limit: the stated amount and the named documents are the whole of the promise.
Surety bonds and financial guarantees
A surety bond and a financial guaranty are an insurer’s or guarantor’s promise to make scheduled payments if the obligor cannot. Municipal bond insurance is the familiar form: the policy runs for the life of the bond and pays according to the original schedule, not in a lump. A parent guarantee works the same way one step closer to home, with the parent’s credit standing behind the subsidiary’s debt.
The holder’s analysis doubles: the underlying obligor on one hand, the promisor on the other. When the two weaken together, the support is at its weakest exactly when it is most needed, and that correlation is the first thing to think about before taking comfort from the wrapper.
At a glance
- Protection: a second party makes the scheduled payments on failure.
- Watch: the promisor’s strength, and how it correlates with the obligor’s.
- Limit: a guarantee from a weakened promisor adds little on the day it matters.
Cash collateral
The simplest outside support is cash placed with an independent institution for the benefit of the holders. Unlike a promise, deposited cash does not depend on anyone’s future solvency to exist; the questions are custody, investment of the balance, and the exact conditions under which it may be paid out or returned.
At a glance
- Protection: deposited cash, held apart from the borrower, covers shortfalls.
- Watch: who holds it, how it is invested, and the release conditions.
- Limit: the balance is finite and, once released, gone.
External and internal supports are usually layered rather than chosen between. A pool may run its own spread and reserve while a letter of credit stands behind a defined slice of the risk. Reading a deal means finding each layer, sizing it, and noting whose promise it rests on. The primer, Document I, sets out the three questions that keep the layers straight.
