for purposes of this Registration Statement to the extent that a statement

Registration Statement.

ITEM 4.  DESCRIPTION OF SECURITIES

         The Principal Select Savings Excess Plan and the Nonqualified Defined
Contribution Plan for Designated Participants (the "Excess Plans") will provide
a select group of management and highly compensated employees of Principal
Financial Group, Inc. and/or certain of its subsidiaries with the opportunity to
elect to defer a specified percentage of their future cash compensation. The
Deferred Compensation Obligations (the "Obligations") of Principal Financial
Group, Inc. (hereinafter in this Item 4, the "Obligor") under the Excess Plans
will be unsecured general obligations of the Obligor to pay the compensation
deferred in accordance with the terms of the Excess Plans, and will rank equally
with other unsecured and unsubordinated indebtedness of the Obligor outstanding
from time to time, payable from the general assets of the Obligor. Because the
Obligor has subsidiary companies, the right of the Obligor, and hence the right
of creditors of the Obligor (including participants in the Excess Plans), to
participate in a distribution of the assets of a subsidiary upon its liquidation
or reorganization or otherwise necessarily is subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Obligor
itself as a creditor may be recognized.




         The amount of compensation to be deferred by each participant (the
"Deferral Account") will be determined in accordance with the Excess Plans based
on elections by the participant. Each Deferral Account generally will be payable
upon termination of employment or on a date selected by the participant in
accordance with the terms of the Excess Plans. The Deferral Account will be
indexed to one or more investment indices (which, among others, may include an
index that tracks the market performance of the Obligor's common stock) chosen
by each participant from a list of such investment indices. Each Deferral
Account will be adjusted to reflect the investment experience of the selected
investment index or indices, including any appreciation or depreciation. The
Obligations will be denominated and payable in United States dollars.

         Benefits under the Excess Plans are generally not subject to
assignment, transfer, pledge or other encumbrance or attachment other than by a
written designation of a beneficiary under the Excess Plans or by operation of
law. A participant may designate persons or entities to receive any balance in
his/her Deferral Account, payable in the event of death.

         The Obligations are not subject to redemption, in whole or in part,
prior to the individual payment dates specified by the participant, at the
option of the Obligor, or through operation of a mandatory or optional sinking
fund or analogous provision. The Obligor reserves the right to amend or
terminate the Excess Plans at any time.

         The Obligations are not convertible into another security of the
Obligor. The Obligations will not have the benefit of a negative pledge or any
other affirmative or negative covenant on the part of the Obligor.

         Amounts deferred under the Excess Plans may be deposited in an
irrevocable grantor trust, in which case such amounts, together with earnings
thereon, are held separate and apart from other funds of the Obligor and are to
be used exclusively for the purpose of making distributions under the Excess
Plans to Excess Plan participants, as beneficiaries of the trust. However, a
beneficiary of the trust has no preferred claim on any assets of the trust prior
to the time such assets are paid to such beneficiary as excess benefits, and all
rights created under the Excess Plans and the trust agreement are mere unsecured
contractual rights of such beneficiary. If the Obligor is insolvent (as defined
in the trust agreement), the trustee must discontinue payments of distributions
under the Excess Plans, and the trust assets become subject to the claims of the
Obligor's general creditors.

         The Obligor's common stock is registered under Section 12 of the
Securities Exchange Act of 1934.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The directors and officers of Principal Financial Group, Inc. may be
indemnified against liabilities, fines, penalties and claims imposed upon or
asserted against them as provided in the Delaware General Corporation Law and
the company's certificate of incorporation and by-laws. Such indemnification
covers all costs and expenses incurred by a director or officer in his or her
capacity as such. The board of directors, by a majority vote of a quorum of
disinterested directors or, under certain circumstances, independent counsel
appointed by the board of directors, must determine that the director or officer
seeking indemnification was not guilty of willful misconduct or a knowing
violation of the criminal law. In addition, the Delaware General Corporation Law
and the company's certificate of incorporation may, under certain circumstances,
eliminate the liability of directors and officers in a stockholder or derivative
proceeding.

         If the person involved is not a director or officer of Principal
Financial Group, Inc., the board of directors may cause the company to
indemnify, to the same extent allowed for the company's directors and officers,
such person who was or is a party to a proceeding by reason of the fact that he
or she is or was an employee or agent of the company, or is or was serving at
the company's request as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise.


                                       2


         The company has policies in force and effect to insure its directors
and officers against such losses that they or any of them will become legally
obligated to pay by reason of any actual or alleged error or misstatement or
misleading statement or act or omission or neglect or breach of duty by such
directors and officers in the discharge of their duties, solely by reason of
their being directors or officers. Such coverage is limited by the specific
terms and provisions of the insurance policies.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED

         Not Applicable.

ITEM 8.  EXHIBITS

         An Exhibit Index, containing a list of all exhibits filed with this
Registration Statement, is included on page 8. The company hereby undertakes,
with respect to any plan described herein that is or is to be qualified under
Section 401 of the Internal Revenue Code, that it has submitted or will submit
such plan and any amendment thereto to the Internal Revenue Service in a timely
manner and has made or will make all necessary changes required by the Internal
Revenue Service in order to qualify such plan.

ITEM 9.  UNDERTAKINGS

         (a) Rule 415 Offering. The undersigned registrant hereby undertakes:

             (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                 (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933, unless the information is contained in periodic
reports filed by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in this
Registration Statement;

                 (ii) To reflect in the prospectus any facts or events arising
after the effective date of this Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in this Registration
Statement, unless the information is contained in periodic reports filed by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in this Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective Registration Statement;

                 (iii) To include any material information with respect to the
plan of distribution not previously disclosed in this Registration Statement or
any material change to such information in this Registration Statement.

             (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

             (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.



                                       3


         (b) Subsequent Exchange Act Documents. The undersigned registrant
hereby undertakes that, for purposes of determining any liability under the
Securities Act of 1933, each filing of the registrant's annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

           (c) Indemnification. Insofar as indemnification for liabilities
arising under the Securities Act of 1933 may be permitted to directors, officers
and controlling persons of the registrant pursuant to the foregoing provisions,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
