INSTRUCTIONS FOR SCHEDULE 13G
INSTRUCTIONS FOR COVER PAGE
(1) Names and Social Security Numbers of Reporting Persons--Furnish the
full legal name of each person for whom the report is filed--i.e., each person
required to sign the schedule itself--including each member of a group. Do not
include the name of a person required to be identified in the report but who is
not a reporting person. Reporting persons are also requested to furnish their
Social Security or I.R.S. identification numbers, although disclosure of such
numbers is voluntary, not mandatory (see "SPECIAL INSTRUCTIONS FOR COMPLYING
WITH SCHEDULE 13G," below).
(2) If any of the shares beneficially owned by a reporting person are held
as a member of a group and such membership is expressly affirmed, please check
row 2(a). If the membership in a group is disclaimed or the reporting person
describes a relationship with other persons but does not affirm the existence of
a group, please check row 2(b) [unless a joint filing pursuant to Rule
13d-1(e)(1) in which case it may not be necessary to check row 2(b)].
(3) The third row is for SEC internal use; please leave blank.
(4) Citizenship or Place of Organization--Furnish citizenship if the named
reporting person is a natural person. Otherwise, furnish place of organization.
(5)-(9), (11) Aggregate Amount Beneficially Owned By Each Reporting
Person, Etc.-- Rows (5) through (9) inclusive, and (11) are to be completed in
accordance with the provisions of Item 4 of Schedule 13G. All percentages are to
be rounded off to the nearest tenth (one place after decimal point).
(10) Check if the aggregate amount reported as beneficially owned in row (9)
does not include shares as to which beneficial ownership is disclaimed pursuant
to Rule 13d-4 [17 CFR 240.13d-4] under the Securities Exchange Act of 1934.
(12) Type of Reporting Person--Please classify each "reporting person" according
to the following breakdown (see Item 3 of Schedule 13G) and place the
appropriate symbol on the form:
Category Symbol
Broker Dealer BD
Bank BK
Insurance Company IC
Investment Company IV
Investment Adviser IA
Employee Benefit Plan, Pension Fund,
or Endowment Fund EP
Parent Holding Company HC
Corporation CO
Partnership PN
Individual IN
Other OO
Notes:
Attach as many copies of the second part of the cover page as are needed,
one reporting person per page.
Filing persons may, in order to avoid unnecessary duplication, answer
items on the schedules (Schedule 13D, 13G or 14D-1) by appropriate cross
references to an item or items on the cover page(s). This approach may only be
used where the cover page item or items provide all the disclosure required by
the schedule item. Moreover, such a use of a cover page item will result in the
item becoming a part of the schedule and accordingly being considered as "filed"
for purposes of Section 18 of the Securities Exchange Act or otherwise subject
to the liabilities of that section of the Act.
Reporting persons may comply with their cover page filing requirements by
filing either completed copies of the blank forms available from the Commission,
printed or typed facsimiles, or computer printed facsimiles, provided the
documents filed have identical formats to the forms prescribed in the
Commission's regulations and meet existing Securities Exchange Act rules as to
such matters as clarity and size (Securities Exchange Act Rule 12b-12).
SPECIAL INSTRUCTIONS FOR COMPLYING WITH SCHEDULE 13G
Under Sections 13(d), 13(g), and 23 of the Securities Exchange Act of 1934
and the rules and regulations thereunder, the Commission is authorized to
solicit the information required to be supplied by this schedule by certain
security holders of certain issuers.
Disclosure of the information specified in this schedule is mandatory,
except for Social Security or I.R.S. identification numbers, disclosure of which
is voluntary. The information will be used for the primary purpose of
determining and disclosing the holdings of certain beneficial owners of certain
equity securities. This statement will be made a matter of public record.
Therefore, any information given will be available for inspection by any member
of the public.
Page 3 of 6 pages
Because of the public nature of the information, the Commission can
utilize it for a variety of purposes, including referral to other governmental
authorities or securities self-regulatory organizations for investigatory
purposes or in connection with litigation involving the Federal securities laws
or other civil, criminal or regulatory statutes or provisions. Social Security
or I.R.S. identification numbers, if furnished, will assist the Commission in
identifying security holders and, therefore, in promptly processing statements
of beneficial ownership of securities.
Failure to disclose the information requested by this schedule, except for
Social Security or I.R.S. identification numbers, may result in civil or
criminal action against the persons involved for violation of the Federal
securities laws and rules promulgated thereunder.
