No withdrawal of negotiable securities deposited by a self-insurer,
shall be made except upon authorization by the Office. A self-insurer
discontinuing business, or discontinuing operations within the purview
of the Act, or providing security for the payment of benefits by
commercial insurance under the provisions of the Act may apply to the
Office for the withdrawal of securities deposited under the regulations
in this part. With such application shall be filed a sworn statement
setting forth:
(a) A list of all outstanding cases in which benefits are being
paid, with the names of the miners and other beneficiaries, giving a
statement of the amounts of benefits paid and the periods for which
such benefits have been paid; and
(b) A similar list of all pending cases in which no benefits have
as yet been paid. In such cases withdrawals may be authorized by the
Office of such securities as in the opinion of the Office may not be
necessary to provide adequate security for the payment of outstanding
and potential liabilities of such self-insurer under the Act.
