Warehouse operators with net worth equal to or greater than the minimum net worth required, but less than the total net worth for the commodity involved in the particular agreement, may satisfy the net worth deficiency by furnishing one of the following:

(a) A bond which:

(1) Is executed by a surety approved by the U.S. Department of the Treasury so long as the surety maintains someone authorized to accept service of legal process in the State where the warehouse is located.

(2) Is executed on either a bond form obtained from CCC, or which is furnished under State law or operational rules for non-governmental supervisory agencies, if approved by CCC, so long as CCC determines that such alternative bond:

(i) Provides adequate protection to CCC;

(ii) Has been executed by a surety approved by the U.S. Department of the Treasury or has an acceptable blanket rider and endorsement executed by such a surety with the liability of the surety under such rider or endorsement being the same as that of the surety under the original bond; and

(iii) Is effective for at least 1 year and cannot be canceled without 120 days notice to CCC. Excess coverage on a bond for one warehouse will not be accepted by CCC against insufficient bond coverage on other warehouses;

(b) Cash and negotiable securities. Any such cash or negotiable securities accepted by CCC will be returned to the warehouse operator when the period for which coverage was required has ended and CCC determines there is no liability under the storage agreement;

(c) An irrevocable letter of credit meeting CCC requirements that is effective for at least 1 year and cannot be canceled without 120 days notice to CCC. The issuing bank must be a commercial bank insured by the Federal Deposit Insurance Corporation or a financial institution subject to the Farm Credit Act; or

(d) Other alternative instruments and forms of financial assurance as the AMS Administrator determines appropriate to secure the warehouse operator's compliance with this section.
