Letters of Credit and Guarantees

What Letters of Credit and Guarantees Are

A letter of credit (LC) is a formal, written commitment issued by a bank—or occasionally another financial institution—to pay a defined amount to a named beneficiary if specified conditions are met. The bank steps in as a creditworthy intermediary between two parties who may not fully trust each other, or where one party needs an independent payment guarantee that does not depend on the counterparty's own financial health. Letters of credit are common in international trade, commercial leasing, and certain regulated industries.

A personal guarantee is an individual's contractual promise to satisfy an obligation—repay a loan, complete a performance, cover a loss—if the primary obligor (usually a business entity) fails to do so. Unlike a letter of credit, a personal guarantee does not involve a bank as intermediary; it runs directly from the guarantor to the creditor. For families with substantial wealth, lenders, landlords, and counterparties often require a personal guarantee from a family member or founder before extending credit to an entity whose standalone balance sheet they consider insufficient.

An indemnity is a related concept: a promise by one party to hold another harmless from certain losses or liabilities. Indemnities appear in purchase agreements, partnership agreements, and real estate contracts and can function similarly to guarantees in practice, even when they are not labeled as such. A qualified attorney must evaluate any specific indemnity language to understand its actual scope.

Standby Letters of Credit in Practice

The standby letter of credit (SBLC) is the form most relevant to wealthy families. Unlike a commercial letter of credit—which is used to finance the movement of goods and is drawn on routinely—a standby LC is meant to remain undrawn. It functions as a backstop: the beneficiary can draw on it only if the underlying obligation is not met. Think of it as a bank-issued insurance policy with a very clean trigger.

Common uses for families include:

• Satisfying lease security deposit requirements for operating real estate or commercial space, in lieu of posting cash
• Supporting a contractor's performance obligation on a large construction project
• Meeting bond or surety requirements in regulated industries
• Providing credit support for a subsidiary whose balance sheet is thin

The bank issuing an SBLC typically requires collateral, a deposit relationship, or a credit facility to back it. That relationship often sits within a family's private banking arrangement. The family pays a fee—expressed in basis points annually on the face amount—rather than tying up cash. If the beneficiary draws on the LC, the bank pays and then has a claim against the family for reimbursement.

Personal Guarantees and Their Reach

Personal guarantees deserve careful attention because they pierce the liability protection that entities like LLCs and corporations are designed to provide. When a family member signs a personal guarantee, the creditor gains direct recourse to that individual's personal assets—not just the entity's assets—in the event of default.

Guarantees come in several forms:

• Full (unconditional) guarantees: The guarantor is immediately liable the moment the primary obligor defaults, without any requirement that the creditor first exhaust remedies against the primary obligor.
• Limited guarantees: Liability is capped at a dollar amount or limited to a specific portion of the obligation.
• Carve-out guarantees (sometimes called "bad boy" guarantees in real estate lending): The guarantor is liable only if certain bad acts occur—fraud, misappropriation of funds, filing a voluntary bankruptcy—rather than for ordinary default. These are common in commercial real estate finance.
• Completion guarantees: Common in development projects, the guarantor promises that a project will be completed, not just that a loan will be repaid.

For families with specialty lending arrangements across aircraft, art, and other assets, guarantee language often appears in documentation that does not prominently advertise its presence. A thorough read of all credit documents—ideally with counsel—is essential before signing.

Guarantee Sprawl Across Family Entities

Consider a hypothetical family—call them the Meredith family—who over two decades built a real estate portfolio, several operating businesses, and a family limited partnership. Each entity's financing was arranged separately. The patriarch signed personal guarantees on three commercial mortgages; a trust co-signed a contractor bond; an LLC operated under a lease supported by an SBLC collateralized by the family's brokerage account. No one had ever compiled these obligations in one place.

This scenario is common and genuinely risky. Guarantee sprawl—the accumulation of guarantee and letter-of-credit obligations across a family's entities without central tracking—creates several problems:

• Total contingent liability is unknown, making risk management estimates unreliable
• Collateral pledged in one facility may limit availability for another
• A default in one entity can trigger cross-default provisions in unrelated facilities
• Estate planning can be complicated because guarantee obligations may become estate liabilities upon death
• New lenders or counterparties do not see the full picture when evaluating creditworthiness

Families sometimes consider maintaining a simple guarantee register—a document listing every outstanding guarantee, LC, and indemnity by entity, counterparty, amount, expiration date, and collateral pledged. This is not a complex system; a well-organized spreadsheet reviewed annually with counsel and the family's advisory team is often sufficient.

Costs, Collateral, and Liquidity Considerations

Letters of credit carry annual fees typically expressed as a percentage of the face amount, negotiated within the family's banking relationship. They also consume credit capacity: a bank that issues a $5 million SBLC has committed $5 million of credit exposure, which may reduce what it will lend elsewhere. Families with large existing credit facilities may find that SBLCs are efficiently priced within those facilities.

Personal guarantees carry no direct out-of-pocket cost at signing, which is precisely why they are easy to sign without full appreciation of the consequences. Their cost is contingent—potentially very large—and realized only when things go wrong.

From a liquidity perspective, collateral pledged against an SBLC is typically unavailable for other uses until the LC expires or is returned. If the underlying obligation runs for several years, that collateral is effectively locked. Families evaluating whether to post cash, pledge securities, or rely on an SBLC should weigh the opportunity cost of each approach alongside the fee.

Important Questions and Common Mistakes

Before signing any guarantee or authorizing an LC, families and their advisers may find it useful to ask:

• What is the exact maximum exposure, and is it capped in the document?
• Does the guarantee run to the individual or to an entity, and which assets are therefore at risk?
• What events trigger the guarantee or allow a draw on the LC?
• Is there a sunset date or a mechanism for the guarantee to be released when the underlying obligation is substantially reduced?
• Does this guarantee contain cross-default language that could accelerate other obligations?
• How does this obligation interact with existing estate planning structures?

Among the most common mistakes: signing guarantee language that is buried in a broader credit agreement without a line-item review; allowing guarantees to remain in place long after the underlying obligation has been substantially repaid; and failing to discuss outstanding personal guarantees with estate planning counsel, since these obligations can affect estate tax calculations and the integrity of certain trust structures. A qualified attorney must review any specific guarantee or indemnity before it is executed.
