31 CFR 225.3 - Pledge of Government obligations in lieu of a bond with surety or sureties.
(a) General. An obligor required by Federal law or regulation to furnish a bond with surety or sureties may give in lieu thereof to a bond official any security acceptable under 31 U.S.C. 9301, as amended. The Secretary will designate classes of Government obligations acceptable under this part.
(b) Bond. The bond, at a minimum, shall irrevocably authorize the bond official to collect, sell, assign, or transfer such Government obligations and any interest retained therefrom in the event of the obligor's default in performing any of the terms, conditions, or stipulations of such bond. Unless otherwise provided by law, the bond shall authorize the bond official to apply the proceeds from the sale, assignment, or transfer of such Government obligations, in whole or in part, to satisfy any costs incurred by the United States related to the default, and to apply any excess proceeds to satisfy any other claim of the United States against the obligor. The bond shall not include any obligations on custodians which are inconsistent with, or in addition to, the obligations in this part. The bond will provide that the bond official may retain any interest accruing upon any Government obligations, or direct that such interest be retained by the custodian.
(d) Avoiding frequent substitutions. To avoid the frequent substitution of Government obligations, the bond official may reject Government obligations which mature, or are redeemable, within one year from the date they are pledged to the bond official.
(e) Acceptable Government obligations. Types and valuations of acceptable collateral security are addressed in 31 CFR part 380. For a current list of acceptable classes of securities and instruments described in 31 CFR part 380 and their valuations, see the Bureau of the Fiscal Service's web site at www.publicdebt.treas.gov.
