Collateral is the asset or instrument a surety holds as security for the bond. It protects the surety from loss if the principal defaults. We accept three forms of collateral — cash, irrevocable letter of credit, and U.S. Treasury-issued securities — and we do not accept real property, tangible assets, UCC filings, or any form of assignment or lien on assets. The collateral framework, the rationale behind it, and the release mechanics are below.
A surety bond is a three-party agreement. The principal owes a duty to the obligee; the surety stands behind that duty with real capital. If the principal defaults, the surety pays the obligee up to the bond limit and then pursues reimbursement from the principal under an indemnity agreement signed at issuance. Indemnity is the surety's first line of recourse.
Collateral is the surety's second line of recourse. It is an asset or instrument the surety holds during the bond's life that the surety can liquidate to make itself whole if the principal defaults and indemnity recovery proves difficult or impossible. The surety holds collateral; the principal retains beneficial ownership and gets it back when the bond is fully and irrevocably released.
Whether a bond requires collateral depends on three variables: the bond class (some classes are inherently collateral-typical — appellate supersedeas bonds, mechanic's lien release bonds, financial guarantee bonds — because the surety expects to pay most claims), the principal's financial position (a principal whose credit and balance sheet support the bond may receive uncollateralized terms; a principal with thin financials may not), and the bond size (the larger the bond, the more often collateral is part of the placement).
What follows is what we accept, what we don't, and how the collateral comes back when the bond is released.
Surety One, Inc. accepts three forms of collateral as security for bonds we underwrite. Every other form — including real property, tangible assets, UCC filings, and any form of assignment or lien on assets — is not accepted. The reasoning is liquidity: the surety must be able to convert collateral to cash quickly if a bond claim materializes, and the three accepted forms convert reliably while alternatives do not.
Several forms of asset are commonly proposed by principals and just as commonly declined by sureties. The reason in each case is liquidity — these forms either cannot be converted to cash on demand, or the conversion process is so cumbersome that the collateral fails its function as a second line of recourse.
Real property. A mortgage or deed of trust on real estate has the right characteristics on paper — substantial value, recorded interest, foreclosable on default — but in practice real estate collateral fails the liquidity test. A surety facing a claim cannot wait six to eighteen months for a foreclosure process to liquidate the property. Real property is therefore not accepted as collateral on any bond we underwrite.
Tangible personal property. Equipment, inventory, vehicles, and other tangible assets present the same liquidity problem as real property. They also depreciate in unpredictable ways and require active management to maintain value. Not accepted.
UCC filings. A perfected security interest in business assets — UCC-1 filing on accounts receivable, inventory, or general intangibles — is not accepted. The same liquidity reasoning applies, plus the priority and notice complications of UCC perfection in default scenarios.
Assignments and liens on assets. Any form of assignment or lien on assets — wage garnishment assignments, judgment liens, equity interests in private companies, partnership interest pledges — is not accepted. These instruments are illiquid by their nature.
The accepted/not-accepted line is bright. If the proposed collateral cannot be converted to cash within days of a default event, it is not collateral for a surety bond. The whole point of the collateral is the surety's certainty of recovery. Anything that defeats that certainty defeats the purpose.
The amount of collateral required depends on three factors: the nature of the obligation, the principal's financial position, and the bond class loss history.
For most collateral-typical bond classes — appellate supersedeas, mechanic's lien release, financial guarantee — collateral is typically required at 100% of the bond penalty. The reasoning is direct: these classes have meaningful loss rates and the surety expects to pay most bonds that get challenged, so full collateral is the conservative underwriting baseline.
For bond classes where collateral is occasionally rather than typically required — plaintiff bonds with strong but not balance-sheet-perfect principals, fiduciary bonds for family-member fiduciaries in our non-standard program — collateral may be required at partial penalty: 25%, 50%, or 75% of the bond amount, depending on the case-specific underwriting analysis.
For principals whose credit and balance sheet meet underwriting thresholds, uncollateralized placement is the standard. Most court bonds in our practice — across all four categories — are uncollateralized. Collateral becomes part of the placement only where the bond class or the principal's profile requires it.
The trade-off is straightforward. Uncollateralized placement requires the principal to qualify on financial strength alone. Collateralized placement — with cash, iLOC, or Treasury securities — opens placement to a wider range of principals, at the cost of tying up the collateral for the life of the bond.
Collateral is released back to the principal only after the surety has received evidence — solely acceptable to the surety — that the surety has been fully and irrevocably released from its obligation under the bond. The release standard is unilaterally the surety's decision, governed by the bond agreement and the indemnity agreement signed at issuance.
The release standard varies by bond class. Each class has its own release mechanics:
Once the release standard for the class is satisfied, the surety initiates the collateral return. Cash collateral is wired back to the principal's account on file. iLOC collateral is returned to the issuing bank with the surety's release authorization. Treasury collateral is reCUSIP'd back to the principal or to a successor custodian per the principal's instructions.
