               The Securities and Exchange Commission ("Commission") deems
          it appropriate and in the public interest that public
          administrative proceedings be, and hereby are, instituted
          pursuant to Sections 203(e) and 203(f) of the Investment Advisers
          Act of 1940 ("Advisers Act") against RhumbLine Advisers
          ("RhumbLine"), and John D. Nelson, ("Nelson") (collectively, the
          "Respondents").

                                         II.

               In anticipation of the institution of these administrative
          proceedings, the Respondents have submitted Offers of Settlement
          ("Offers"), which the Commission has determined to accept.
          Solely for the purpose of these proceedings, and any other
          proceedings brought by or on behalf of the Commission, or to
          which the Commission is a party, and without admitting or denying
          the findings contained herein, except those findings pertaining
          to the jurisdiction of the Commission over them and over the
          subject matter of these proceedings, which they admit, the
          Respondents each consent to the entry of the findings and the
          Order set forth herein.




                                             III.

               On the basis of this Order and the Offers submitted by the
          Respondents, the Commission finds that: [1]

          A.   Respondents

               1.   RhumbLine is located in Boston, Massachusetts and is
          registered with the Commission as an investment adviser. (File
          No. 801-37845).  The firm has approximately nine employees, 50
          clients and $3.7 billion of assets under management.  RhumbLine's
          business consists primarily of managing equity index funds for
          public and private pension plans.

               2.   Nelson is the founder and was at all relevant times the
          chief executive officer ("CEO") of RhumbLine.  During the times
          relevant herein, Nelson was responsible for all of RhumbLine's
          operations and investment management activities.

          B.   Other Relevant Person and Entities

               1.   From 1991 through October 1996, RhumbLine employed a
          chief investment officer ("CIO") who was responsible for
          developing and implementing an options trading program to
          complement RhumbLine's management of equity index funds.

               2.   AT&T Corp., a New York corporation engaged in the
          telecommunications business, administered during the relevant
          time employee benefit and pension plan assets through its
          subsidiary, AT&T Investment Management Corporation ("AT&T").
          From 1992 through September 1996, AT&T was a client of
          RhumbLine's options trading program.  AT&T also was a client of
          another RhumbLine investment program not involved in this matter.

               3.   Massachusetts Pension Reserves Investment Trust
          ("PRIT") contains the assets of the Massachusetts state employee
          and teachers retirement system.  From 1992 through September
          1996, PRIT was a client of RhumbLine's options trading program.
          PRIT also was a client of other RhumbLine investment programs not
          involved in this matter.

          C.   Findings

               1. Summary

               This matter involves RhumbLine's and Nelson's failure
          adequately to supervise the CIO.  From January 1995 through
          September 1996, the CIO engaged in certain unauthorized trading
          and concealed and misrepresented losses in the AT&T options
          account, and engaged in certain unauthorized trading in the PRIT
          account in violation of the antifraud provisions of the
          Securities Act of 1933 ("Securities Act"), the Securities
          Exchange Act of 1934 ("Exchange Act"), and the Advisers Act.   As
          a result, the AT&T options account, sustained losses through
          September 23, 1996 of approximately $150 million.[2]  The PRIT
          options account sustained losses of approximately $12 million.
          The CIO was able to place unauthorized trades and misrepresent
          losses in part because RhumbLine and Nelson failed to respond to
          certain red flags, which should have alerted them to the CIO's
          activities.  Further, RhumbLine did not have procedures to
          monitor the CIO's trading or his reporting of performance.
          Consequently, RhumbLine and Nelson failed reasonably to supervise
          the CIO with a view to detecting and preventing his securities
          law violations.

                2.  Unauthorized Trading and Misstatements
                    of Losses in the AT&T Options Account

               In 1991, RhumbLine hired the CIO, who had presented to
          RhumbLine a plan to develop the options trading program.
          RhumbLine eventually obtained four clients for the options
          program, including AT&T and PRIT.  Prior to retaining the CIO and
          after his departure, RhumbLine did not engage in options trading
          on behalf of its clients.

               The investment objective for the AT&T options account was to
          earn consistent, incremental premium income by writing:  (1) call
          options on stocks and sector indices contained in a $165 million
          Standard & Poor's ("S&P") portfolio; and (2) put and call option
          spreads on the S&P 100 and S&P 500 indices.  AT&T and RhumbLine
          executed written account guidelines, which prohibited certain
          trades, including in-the-money options; naked, short S&P 100 and
          S&P 500 options; S&P 100 and S&P 500 options that exposed the
          account to a risk of loss greater than $6 million; and options
          written against greater than approximately $25 million in
          technology sector assets.

               From January 1995 through September 1996, the CIO engaged in
          unauthorized trading in the AT&T account by placing options
          trades that represented attempts to profit on the future
          direction of the market.  When his strategy was not successful,
          the CIO rolled positions forward and thereby avoided having to
          realize losses.  Such trading was inconsistent with AT&T's
          investment objective of seeking only premium income.  Some of the
          CIO's trading also violated the written guidelines governing the
          account.  He wrote naked, short S&P 100 and S&P 500 index
          options, and he exposed the account to a risk of loss greater
          than its $6 million loss constraint.  The CIO wrote options
          against hundreds of millions of dollars of technology sector
          assets, instead of the approximately $25 million permitted by the
          guidelines.

               During the third quarter of 1996, the CIO concealed his
          unauthorized trading by misrepresenting and failing to disclose
          losses in the AT&T options account.  On July 19, 1996; August 6,
          1996; and August 29, 1996, in written and oral performance
          reports to representatives of AT&T, the CIO falsely understated
          losses by approximately $26 million to $43 million.  The CIO did
          not disclose the account's mounting losses to representatives of
          AT&T.  Upon learning of the losses, Nelson informed AT&T on
          September 19, 1996.  AT&T thereafter suspended trading in the
          account.  Total losses in the AT&T options account from January
          1996 through September 23, 1996 were approximately $150 million.
          [3]

               3.   Unauthorized Trading in the PRIT Account

               The investment objective for the PRIT options account was to
          earn incremental premiums by writing S&P 100 and S&P 500 index
          option spreads.  PRIT and RhumbLine executed written guidelines,
          which prohibited, among other things, writing options that
          exposed the account to a risk of loss greater than four percent
          of the value of PRIT's underlying stock portfolio, as of the
          beginning of the year.

               In the PRIT account, as in the AT&T account, beginning in
          April 1995, instead of following the investment objective of
          earning incremental premium income, the CIO attempted to profit
          on the future direction of the market.  He wrote in-the-money and
          at-the-money options, and he rolled positions forward to avoid
          realizing losses.  On at least three occasions, the CIO violated
          PRIT's written guidelines by exceeding the account's four percent
          loss constraint.  On September 18, 1996, Nelson, who had not
          previously known that the CIO had exceeded PRIT's loss
          constraint, informed PRIT of the losses.  Total 1996 losses in
          the PRIT options account were approximately $12 million. [4]

               By the conduct described above, the CIO violated Section
          17(a) of the Securities Act and Section 10(b) of the Exchange Act
          and Rule 10b-5 thereunder, and he aided and abetted violations of
          Sections 206(1) and 206(2) of the Advisers Act.

                4.  Nelson Failed to Detect the CIO's Unauthorized Trading

               Certain red flags should have alerted Nelson to the CIO's
          activities.  During the spring of 1995, Nelson reviewed the
          positions in the clients' accounts and determined that the CIO
          had written uneven numbers of put and call option spreads on the
          S&P 100 and S&P 500 indices.  Although this was an indication
          that the CIO was trading in a manner that was inconsistent with
          the accounts' investment objectives, Nelson took no additional
          steps to detect or prevent unauthorized trading by the CIO.
          During the summer of 1996, Nelson noticed options written against
          technology sector assets in the AT&T account in an amount in
          excess of the $25 million limit contained in AT&T's written
          guidelines.  He questioned the CIO, who asserted that AT&T had
          authorized him to write the positions.  Despite knowing that the
          written guidelines prohibited positions of the size written,
          Nelson failed unreasonably to verify the CIO's assertion.
          Finally, Nelson knew that, in early 1996, the AT&T account had
          sustained large losses, and that AT&T had expressed concern about
          those losses.  Despite this knowledge, he did not institute
          additional procedures to monitor the CIO's trading.

               Nelson allowed the CIO to exercise complete control over all
          aspects of the options trading program, and no one regularly
          checked his trades to ensure that they complied with client
          guidelines.  In addition, the CIO had complete control over
          calculating and reporting performance for the options accounts.

                5.  RhumbLine Lacked Controls and Procedures
                    Relating to Options

               RhumbLine had no policies or procedures designed to detect
          or prevent unauthorized trading in the options clients' accounts.
          The firm had no system for risk management or for monitoring the
          CIO's trading.  Nelson relied exclusively on unverified oral
          reports from the CIO to monitor the options trading program.
          There was no segregation of responsibility for placing and
          valuing trades.  Moreover, there was no procedure to ensure that
          the CIO correctly calculated or adhered to client loss
          constraints.

          D.   Failure Reasonably to Supervise

               1. Standards of Supervision

               Under Sections 203(e)(6) and 203(f) of the Advisers Act, the
          Commission may seek sanctions where an investment adviser or an
          associated person has failed reasonably to supervise, with a view
          to preventing violations of the federal securities laws and rules
          thereunder, another person subject to the investment adviser's or
          associated person's supervision who commits such violations.  See
          Van Kampen American Capital Asset Mgmt., Advisers Act Rel. No.
          1525 (Sept. 29, 1995), 60 SEC Docket 1284; Kemper Fin. Serv.,
          Inc., Advisers Act Rel. No. 1494 (June 6, 1995), 1995 SEC LEXIS
          1311 (settlement).  The Commission has repeatedly emphasized that
          the duty to supervise is a critical component of the federal
          regulatory scheme.  See John H. Gutfreund, Exchange Act Rel. No.
          31554 (Dec. 3, 1992), 52 SEC Docket 4370, 4386.  Management bears
          responsibility for ensuring that procedures reasonably designed
          to prevent and detect wrongdoing are adopted, and to take
          appropriate steps if it receives indications that such procedures
          are not working.  First Capital Strategists, Advisers Act Rel.
          No. 1648 (Aug. 13, 1997), 1997 SEC LEXIS 1646 (investment adviser
          and its partners failed to supervise trader who engaged in
          unauthorized trading; noting that it was insufficient to rely on
          trustworthiness of trader without independently reviewing
          positions); Van Kampen American Capital Asset Mgmt., 60 SEC
          Docket at 1284 (finding that investment adviser failed to
          supervise because it gave complete control over pricing
          procedures to portfolio manager).

                 Supervisors must respond vigorously to indications of
          possible wrongdoing.  See Kemper Fin. Serv., Inc., 1995 SEC Lexis
          1311; see also Gutfreund, 52 SEC Docket at 4386-87; Wedbush Sec.,
          Inc., 48 S.E.C. 963, 967 (1988) (especially imperative that those
          in authority exercise particular vigilance when indications of
          irregularity reach their attention).  Red flags and suggestions
          of irregularities demand inquiry as well as adequate follow-up
          and review.  When indications of impropriety reach the attention
          of those in authority, they must act decisively to detect and
          prevent violations of the federal securities laws.   Kemper Fin.
          Serv., Inc., 1995 SEC Lexis 1311 (quoting Edwin Kantor, Exchange
          Act Rel. No. 32341 (May 20, 1993), 54 SEC Docket 293, 301); see
          also Michael H. Hume, Exchange Act Rel. No. 35608 (Apr. 17,
          1995), 1995 SEC Lexis 983 (a failure to supervise can arise where
          a supervisor was aware only of red flags or suggestions of
          irregularity); Frederick H. Joseph, Exchange Act Rel. No. 32340
          (May 20, 1993), 54 SEC Docket 283, 291.  The Commission has
          consistently stressed the importance of vigilant supervision.
          See, e.g., Smith Barney, Harris Upham & Co., Exchange Act Rel.
          No. 21813 (March 5, 1985), 32 SEC Docket 999, 1010.

               2.   RhumbLine And Nelson Failed Reasonably
                    to Supervise the CIO

               As a result of the conduct described above, RhumbLine and
          Nelson failed reasonably to supervise the CIO, who was subject to
          their supervision within the meaning of Section 203(e)(6) of the
          Advisers Act, with a view to preventing his violations of Section
          17(a) of the Securities Act and Section 10(b) of the Exchange Act
          and Rule 10b-5 thereunder, and his aiding and abetting of
          violations of Sections 206(1) and 206(2) of the Advisers Act.

                                         IV.

               In view of the foregoing, the Commission deems it
          appropriate and in the public interest to accept the Offers of
          Settlement submitted by RhumbLine and Nelson and to impose the
          sanctions agreed to in the Offers.

                                          V.

                         Accordingly, IT IS HEREBY ORDERED, pursuant to Sections
          203(e), 203(f) and 203(i) of the Advisers Act, that:

          his suspension from association;

               C.   Nelson shall, within 30 days of the entry of this
          Order, pay a civil money penalty in the amount of $10,000 to the
          United States Treasury.  Such payment shall be: (a) made by

               F.   RhumbLine shall comply with its undertakings to:

               1.   retain, at its own expense, within 30 days of the entry
          of this Order, the services of an independent consultant (the
          "consultant") who is not unacceptable to the Commission staff and
          who shall review RhumbLine's supervisory, compliance and other
          policies and procedures designed to prevent and detect federal
