                                     PART I


Item 1. Business

        The  Registrant  is  a  separate  account  established  under  the  Iowa
        insurance  laws and  regulations  as  Principal  Mutual  Life  Insurance
        Company Separate  Account C on April 12, 1971,  pursuant to a resolution
        of the Executive Committee of the Board of Directors of Principal Mutual
        Life  Insurance  Company.   Principal  Mutual  Life  Insurance  Company,
        formerly  known as Bankers Life Company,  adopted its new name effective
        July 1, 1986. The account was formed to receive payments under Principal
        Mutual Life Insurance Company  Contracts  designed for use in connection
        with  pension  or  profit   sharing   plans  which   qualify  under  the
        Self-Employed  Individuals  Tax  Retirement  Act  of  1962,  as  amended
        ("HR-10").  Principal  Mutual  Life  Insurance  Company is a mutual life
        insurance company,  incorporated under the laws of Iowa,  offering life,
        disability,  health and annuity  contracts  written on an individual and
        group basis.

        Pursuant to the Amendments enacted in 1970 to the Investment Company Act
        of 1940,  the Account is not an  investment  company for purposes of the
        Act.

        The objective of these  Contracts is to provide for the  accumulation of
        retirement  funds and to provide for  payments,  usually  commencing  at
        retirement,  which  tend to reflect  changes in the cost of living  both
        during the years prior to and the years  following the  commencement  of
        annuity payments.  With Bankers Flexible Annuity Contracts (Registration
        No. 2-39957),  Principal Mutual Life Insurance  Company,  as a depositor
        for the Account,  seeks to  accomplish  this  objective by investing the
        payments  made  under  the  Contracts  in shares  of  Principal  Capital
        Accumulation  Fund,  Inc.  which invests  principally  in common stocks.
        Similarly,  with Pension Builder Contracts  (Registration No. 33-58028),
        it seeks to accomplish  this objective by investing  payments made under
        the Contract in three Divisions.  One is a "Common Stock Division" where
        payments are invested in shares of Principal Capital  Accumulation Fund,
        Inc. Another is a "Money Market Division" where payments are invested in
        Principal  Money Market Fund,  Inc.  which invests in  short-term  money
        market  instruments.  The third  Division  is a  "Government  Securities
        Division" where payments are invested in Principal Government Securities
        Fund,  Inc.,  which invests in  obligations  issued or guaranteed by the
        United States Government or its agencies.  There may be a combination of
        investments in the three Divisions, as directed by Participants.

        Except for those Contracts described above with payments credited to the
        Registrant  (Principal Mutual Life Insurance Company Separate Account C)
        and Variable  Annuity  Contracts and Variable Life  Insurance  Contracts
        with  payments  credited  to  Principal  Mutual Life  Insurance  Company
        Separate Account B and Variable Life Separate Account, respectively, the
        Company  distributes its own products as permitted under the laws of the
        various jurisdictions in which the Company is authorized to do business,
        namely the fifty states of the United States,  the District of Columbia,
        the  Commonwealth of Puerto Rico and the Canadian  provinces of Alberta,
        British  Columbia,  Manitoba,  Ontario and Quebec.  Such distribution is
        through a field agency system of approximately 1,320 full-time agents, a
        group insurance sales  organization of approximately 207 individuals and
        through a large number of independent insurance brokers.

        The Contracts  described above with payments  credited to the Registrant
        and  other  Variable  Annuity  Contracts  and  Variable  Life  Insurance
        Contracts   are   distributed   through   Princor   Financial   Services
        Corporation,  an affiliated  broker-dealer  offering open-end management
        investment company shares, variable annuities,  variable life insurance,
        interests in limited  partnerships and general securities to the public.
        Such Contracts are sold primarily by registered  representatives  of the
        broker-dealer  who are also insurance agents of or brokers for Principal
        Mutual Life  Insurance  Company and authorized by applicable law to sell
        life  and  other  forms  of  personal  insurance  and who are  similarly
        authorized to sell variable  annuities.  Such Contracts may also be sold
        through other selected broker-dealers.

        The  Registration  Statement  filed by the Registrant was made effective
        September  13,  1971,  and the first  sale of Bankers  Flexible  Annuity
        Contracts occurred on October 8, 1971.  Effective January 4, 1989, sales
        of Bankers Flexible Annuity Contracts were discontinued.

        In 1982  the  Registrant  filed a  Registration  Statement  in File  No.
        2-78747,  to  register  a  new  class  of  securities  (called  "Pension
        Builder")  for the same  HR-10  plan  market  utilizing  the  contingent
        deferred sales charge  concept.  The  registration  for Pension  Builder
        contracts first became effective on May 5, 1983 and the first sale under
        the Pension Builder Contract was made on September 19, 1983.

        In 1989 the Registrant  filed a new  Registration  Statement in File No.
        33-27256  for the  contracts  in view of the fact that  aggregate  sales
        under  the  prior  registration   statement  approached  the  amount  of
        contracts  registered  thereunder.  The  contracts  offered  by the  new
        registration  statement are identical to contracts previously registered
        under the 1933 Act in File No. 2-78747.

        In 1993 the Registrant  filed a new  Registration  Statement in File No.
        33-58028  for the  contracts  in view of the fact that  aggregate  sales
        under  the  prior  registration   statement  approached  the  amount  of
        contracts  registered  thereunder.  The  contracts  offered  by the  new
        registration  statement are identical to contracts previously registered
        under the 1933 Act in File No. 33-27256.

Item 2. Properties

        The Registrant owns no physical properties.  The principal properties of
        the Depositor,  Principal  Mutual Life Insurance  Company,  are its home
        office complex at The Principal Financial Group in Des Moines, Iowa.


Item 3. Legal Proceedings

        Matters

        a.    The  Registrant  does  not  issue  common  stock.   The  Contracts

              Services  Corporation,   an  affiliated   broker-dealer   offering
              open-end management investment company shares, variable annuities,
              variable life  insurance,  interests in limited  partnerships  and
              general  securities  to  the  public.   Such  Contracts  are  sold
              primarily by registered  representatives  of the broker-dealer who
              are also insurance  agents of or brokers for Principal Mutual Life
              Insurance  Company and  authorized by applicable  law to sell life
              and  other  forms  of  personal  insurance  and who are  similarly
              authorized to sell variable annuities.  Such Contracts may also be

                         Report of Independent Auditors


Board of Directors and Participants
Principal Mutual Life Insurance Company


We have audited the  accompanying  statement  of net assets of Principal  Mutual
Life Insurance Company Separate Account C (comprising,  respectively, the Common
Stock,  Government  Securities,  and Money Market  Divisions) as of December 31,
1995,  and the related  statements  of operations  for the year then ended,  and
changes in net assets for each of the two years in the period then ended.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1995, by correspondence with
the transfer agent. An audit also includes  assessing the accounting  principles
used and  significant  estimates made by  management,  as well as evaluating the
overall financial statement  presentation.  We believe that our audits provide a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Principal Mutual Life Insurance
Company  Separate  Account  C at  December  31,  1995,  and the  results  of its
operations  for the year then ended,  and the changes in its net assets for each
of the two years in the period then ended, in conformity with generally accepted
accounting principles.
