Important information is contained in the notes at the end of this circular. Please read the Notes carefully.
(a) All Certificates of Authority expire July 31, and are renewable August 1, annually. Companies holding Certificates of Authority as acceptable sureties on Federal bonds are also acceptable as reinsuring companies.
(b) The Underwriting Limitations published herein are on a per bond basis. Treasury requirements do not limit the penal sum (face amount) of bonds which surety companies may provide. However, when the penal sum exceeds a company's Underwriting Limitation, the excess must be protected by co-insurance, reinsurance, or other methods in accordance with 31 CFR Section 223.10, Section 223.11.
(c) A surety company must be licensed in the state or other area in which it provides a bond, but need not be licensed in the State or other area in which the principal resides or where the contract is to be performed [28 Op. Atty. Gen. 127, Dec. 24, 1909; 31 CFR Section 223.5 (b)]. The term "other area" includes the District of Columbia, American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the Virgin Islands.

(e) Companies holding Certificates of Authority as acceptable reinsuring companies are acceptable only as reinsuring companies on Federal bonds and may not directly write Federal bonds.
