SEC's Collection of Information
-------------------------------

An agency may not conduct or sponsor, and a person is not required to respond
to, a collection of information unless it displays a currently valid OMB control
number. A fund that wishes to deregister and is in one of the four categories in
Instruction 1 may use this form. The principal purpose of this collection of
information is to enable the Commission to determine that a registered
investment company has ceased to be an investment company as defined by the Act
or is a business development company. The Commission estimates that the burden
for completing this form will be approximately 3 hours per filing. Any member of
the public may direct to the Commission any comments concerning the accuracy of
the burden estimate of this form, and any suggestions for reducing this burden.
This collection of information has been reviewed by the Office of Management and
Budget in accordance with the clearance requirements of 44 U.S.C. ss. 3507.
Responses to this collection of information will not be kept confidential.
