1. Quick definitions — guarantee vs SBLC

Corporate guarantee. A direct promise by Company A to pay Company B’s debt if the borrower defaults. It’s not bank paper. On a miss, the lender demands payment from the guarantor.

SBLC. A bank-issued standby that pays against a complying demand when the borrower defaults. Most U.S. transactions reference ISP98. Many international deals use URDG 758.

2. Eligibility & set-up — who can back whom

Banks want a guarantor that can absorb the full downside: listed parent with conservative leverage, sovereign-linked vehicle, or a private group with three years of solid auditeds. The guarantor’s board approves a hard cap. Without that resolution, nothing moves. For SBLCs, the issuing bank must clear its own credit before issuance.

Usual blockers: sanctions exposure, negative pledge or guarantee-limits in existing covenants, shareholder approval thresholds. Skip diligence and your timeline drifts by months.

3. Drafting the guarantee agreement — remove wiggle room

Use a standalone document that states, in plain terms:

• Liabilities covered: principal, interest, break costs, fees.
• Expiry or drop-away triggers tied to leverage, ratings, or amortization.
• Events of default: non-payment, insolvency, covenant breach.
• Notice mechanics kept simple to avoid disputes.
• Subrogation so the guarantor can recover from the borrower after payout.

Ambiguity invites litigation. Clean drafting now prevents fights later.

4. SBLC text — choose ISP98 or URDG 758 (not both)

If the backstop is an SBLC, pick one rulebook and keep the language tight:

• ISP98. Standby-focused rules common in the U.S.; addresses draw formats, handling of document errors, evergreen extensions.
• URDG 758. Demand-guarantee approach used widely in Europe, the Middle East, and Africa; pays on a “complying demand.”

Mixing frameworks confuses issuance and can delay payment at draw.

5. Collateral pledge & UCC Article 9 perfection

Even with a strong guarantee, lenders often secure hard collateral to lock priority:

• File a UCC-1 financing statement over shares, receivables, equipment, IP.
• Record mortgages or deeds of trust for real estate.
• Register security in every relevant jurisdiction holding material assets.

File early. Registry timestamps set priority, not the signing date.

6. Monitoring & reporting — no surprises

Lenders monitor the guarantor as closely as the borrower. Expect to deliver:

• Monthly or quarterly management accounts and audited financials.
• Covenant compliance certificates.
• Proof UCC filings remain live (continuations before five-year lapse).

Miss a continuation and first-lien status can slide. That is avoidable.

8. FAQs — straight answers

Does a guarantee hit the parent’s balance sheet?

Under IFRS and U.S. GAAP, it is a contingent liability disclosure. No cash leaves unless called, but rating agencies track the exposure.

Is a corporate guarantee cheaper than an SBLC?

Usually. A guarantee has no annual bank fee. Some lenders still prefer the credit signal of a top-tier bank’s SBLC over a private guarantor.

How long from term sheet to perfected security?

With experienced counsel and fast approvals, four weeks is realistic. Cross-border security or slow boards can push this to three months.

What if the guarantor sits in another country?

Cross-border guarantees work, subject to conflict-of-laws checks and local opinions. In some cases, an onshore SBLC is added to simplify enforcement.

Can the guarantor cap liability?

Yes. Set a hard dollar cap or tie it to a percentage of the facility. Tighter caps reduce lender comfort and can lift the margin.

Do UCC filings really expire every five years?

Yes. File the continuation within the six-month window before the fifth anniversary or the filing lapses and priority can be lost.

9. Final take

Guarantees and SBLCs transfer risk from a thin borrower to a stronger pocket. Draft clean documents, file security early, monitor continuously. Miss any of those and negotiating leverage swings back to the bank.
