Secured Corporate Bond

A secured corporate bond is a bond backed by a pledge of specific assets—real estate, equipment, inventory, or intellectual property—that the bondholder can seize and liquidate if the issuer defaults. This collateral pledge creates a perfected lien that gives secured bondholders priority claim ahead of debenture holders and general creditors in bankruptcy.

Collateral transforms the creditor relationship

When a corporation issues a secured bond, it earmarks specific assets as security for the debt. These might be manufacturing plants, commercial real estate, vehicles, intellectual property, or a portfolio of accounts receivable. A legal document called a mortgage (for real estate) or security agreement (for other assets) creates a lien—a claim that the bondholder can enforce against that property.

Unlike a debenture, where the lender’s claim is general and ranks behind all secured creditors in insolvency, a secured bondholder has a legal right to take possession of and sell the pledged assets to recover the debt. This materially strengthens the creditor’s position and lowers the risk of loss in default, which is why secured bonds typically offer lower yields than unsecured debt from the same issuer.

Why corporations pledge collateral

A corporation pledges collateral when it needs to borrow but lacks the credit quality to raise funds on an unsecured basis at an acceptable rate. A startup or distressed firm may find that no one will buy its debentures, but by pledging its main assets as security, it can convince lenders to extend credit at a manageable cost.

Alternatively, a corporation might issue both secured and unsecured bonds. A strong company might float unsecured debentures for general corporate purposes and secured bonds backed by a real estate portfolio for a specific capital project. The secured tranche typically pays a lower rate because bondholders accept less risk.

In project finance, secured bonds are standard. A corporation financing a new power plant or toll road will issue bonds secured by the revenue stream and underlying assets of that project. The bondholder’s claim is not on the issuer’s general balance sheet but on the project’s specific cash flows and collateral.

The hierarchy in insolvency

In a bankruptcy, secured creditors are paid before unsecured ones. If a company owes £100 million on a secured bond backed by a real estate portfolio worth £80 million, the bondholder seizes the property, sells it, and recovers the £80 million. It then becomes an unsecured creditor for the remaining £20 million claim, competing with debentures, trade payables, and other general creditors.

This priority is why the law distinguishes between secured and unsecured debt. Secured bondholders have a first charge on the collateral; other lenders have no claim on that property. This ordering reflects economic reality: the lender with collateral has less loss severity and should therefore accept a lower rate.

However, priority is not absolute. A corporation can pledge the same asset to multiple lenders if each lien is properly subordinated (junior liens rank second, third, and so on). A property might be pledged first to a bank mortgage, second to the secured bondholder, and third to a lease company. On liquidation, the first lienholder recovers fully from the asset sale before the second has any claim.

Measuring collateral coverage

Investors and rating agencies focus on two metrics: the loan-to-value ratio (LTV) and debt service coverage. An LTV of 70% means the bondholder can borrow up to 70% of the collateral’s appraised value, leaving a 30% cushion. If the asset falls in value, the bondholder’s margin of safety erodes.

A mortgage-backed bond, for instance, might be issued with a 60% LTV against a real estate portfolio. If the buildings are appraised at £100 million, the bond can be £60 million. A 20% decline in property values reduces the margin of safety to 40%—still comfortable but tighter.

Debt service coverage ratio (the ratio of collateral cash flow to annual bond interest and principal) is equally important. A toll road bond might have a DSCR of 1.5, meaning annual revenues are 1.5 times the amount needed to pay bondholders. A ratio below 1.0 signals the collateral cannot sustain the debt from its own cash generation.

Types of collateral

Real estate is the most common pledged collateral. Corporate campus buildings, manufacturing facilities, shopping centres, and office towers all secure bonds regularly. Real estate is visible, insurable, and easy to value, making it attractive to lenders.

Equipment and vehicles can also be pledged, though they depreciate faster than real estate and are harder to sell quickly in a downturn.

Intellectual property—patents, trademarks, copyrights—can be collateral, but it is harder to value and may lose value if the company fails to invest in maintaining or marketing it.

Receivables (amounts owed to the company by customers) can be securitised; the bondholder receives a claim on customer payments. Mortgage-backed securities are a large category where the collateral is a pool of residential mortgages.

Cash or securities can be pledged too, though this is rare for long-term bonds; it is more common in short-term commercial paper facilities.

The cost of collateral

Pledging collateral is not free. The corporation must create and maintain the lien (legal and recording costs), obtain title insurance in some cases, and arrange for independent collateral monitoring or appraisals. The collateral is also illiquid: the company cannot easily sell a pledged building without the bondholder’s consent.

These costs, though modest relative to the interest savings, do mean that a secured bond is more expensive to issue than a debenture from a documentation and compliance standpoint.

Secured bonds vs. debentures

A corporation with an investment-grade credit rating will typically issue debentures because the cost of unsecured borrowing is low and the administrative burden of pledging collateral is not worth it. A sub-investment-grade or distressed company may have no choice but to issue secured bonds; investors will not buy its debentures at any reasonable rate.

The yield differential (the spread between a secured and unsecured bond from the same issuer) varies with market conditions and credit risk. In stable times, the spread may be 50 basis points; in stress, it can widen to 200 basis points or more.
