Section 13 provides that "any bond shall be in a form or of a type approved by the Secretary, including individual bonds or schedule or blanket forms of bonds which cover a group or class". Any form of bond which may be described as individual, schedule or blanket in form or any combination of such forms of bonds shall be acceptable to meet the requirements of section 13, provided that in each case, the form of the bond, in its particular clauses and application, is not inconsistent with meeting the substantive requirements of the statute for the persons and plan involved and with meeting the specific requirements of the regulations in this part. Basic types of bonds in general usage are:
Note: For the purpose of section 13, blanket bonds which are either aggregate penalty or multiple penalty in form shall be permissible if they otherwise meet the requirements of the Act and the regulations in this part.
Bonding, to the extent required, of persons indirectly employed, or otherwise delegated, to perform functions for the plan which are normally performed by "administrators, officers, or employees" as described in § 2580.412-3(d) may be accomplished either by including them under individual or schedule bonds or other forms of bonds meeting the requirements of the Act, or naming them in what is known under general trade usage as an "Agents Rider" attached to a Blanket Bond.
