For purposes of this subpart--
(a) The terms claim and debt are deemed synonymous and
interchangeable. They refer to an amount of money or property which has
been determined by an appropriate agency official to be owed to the
United States from any person, organization or entity, except another
federal agency.
(b) A debt is considered delinquent if it has not been paid by the
date specified in the agency's initial demand letter (Sec. 20.54),
unless satisfactory payment arrangements have been made by that date, or
if, at any time thereafter, the debtor fails to satisfy his obligations
under payment agreement with the Department of Labor, or any agency
thereof.
