Collateral is assets provided to secure
an obligation. Traditionally, banks might require corporate borrowers to
commit company assets as security for loans. Today, this practice is called
secured lending or asset-based
lending. Collateral can take many forms: property, inventory,
equipment, receivables, oil reserves, etc.
A more recent development is
collateralization arrangements used to secure
repo,
securities lending and
derivatives
transactions. Under such arrangement, a party who owes an obligation
to another party posts collateral—typically consisting of cash or
securities—to secure the obligation. In the event that the party defaults
on the obligation, the secured party may seize the collateral. In this
context, collateral is sometimes called margin.
An arrangement can be unilateral with just one party posting
collateral. With two-sided obligations, such as a
swap or foreign exchange
forward, bilateral collateralization may be used. In that situation, both
parties may post collateral for the value of their total obligation to the
other. Alternatively, the net obligation may be collateralized—at any
point in time, the party who is the net obligator posts collateral for the
value of the net obligation.
In a typical collateral arrangement, the secured obligation is
periodically marked-to-market, and the collateral is adjusted to reflect
changes in value. The securing party posts additional collateral when the
market value has risen, or removes collateral when it has fallen. The collateral agreement should specify:
Acceptable collateral: A secured party will usually
prefer to receive highly rated collateral such as
Treasuries or
agencies. Collateral whose market value is volatile or negatively
correlated with the value of the secured obligation is generally
undesirable.
Frequency of margin calls: Because the value of
an obligation and the value of posted collateral can change, a
secured party typically wants to mark-to-market frequently, issuing a
margin call to the securing party for additional collateral when
needed.
Haircuts: In determining the amount of collateral that
must be posted, haircuts are applied to the market value of various
types of collateral. For example, if a 1% haircut is applied to
Treasuries, then Treasuries are valued at 99% of their market value. A
5% haircut might be applied to certain
corporate bonds, etc.
Threshold level: Only the value of an obligation above
a certain threshold level may be collateralized. For example, if a USD
1MM threshold applies to a USD 5MM obligation, only USD 4MM of the
obligation will actually be collateralized.
Close-out and termination clauses: The parties must
agree under what circumstances the obligation will be terminated. The
form of a final settlement in the event of such termination—and the role
of the collateral in such settlement—is specified.
Valuation: A methodology for marking both the
obligation and the collateral to market must be agreed upon.
Rehypothecation rights: The secured party may wish to
have use of posted collateral—possibly lending it to another party or
posting it as collateral for its own obligations to another party.
Rehypothecation is not permitted in many jurisdictions.
Legal treatment of collateral varies from one jurisdiction to another.
In some jurisdictions, the secured party takes legal possession of
collateral, but is legally bound by how the collateral may be used and the
conditions upon which it must be returned. Such transfer of title provides
the secured party a high degree of assurance that it may seize the
collateral in the event of a default. Transfer of title, however, may be
treated as a taxable event in some jurisdictions. In other jurisdictions, the securing party retains ownership of
collateral, but the secured party acquires a perfected
interest in it.
