investment,  assuming (1) 5% annual return and (2) redemption at the end of each
time period:

                               1 Year .........$ 4
                               3 Years $13

THE AMOUNTS LISTED IN THE EXAMPLE SHOULD NOT BE CONSIDERED AS  REPRESENTATIVE  
OF PAST OR FUTURE  EXPENSES AND ACTUAL EXPENSES MAY BE GREATER OR LESS THAN 
THOSE INDICATED. MOREOVER, WHILE THE EXAMPLE ASSUMES A 5% ANNUAL RETURN,

DESCRIPTION OF THE PORTFOLIO

         Investment Objective

     The goal of the Wilshire 5000 Index Portfolio is to replicate as closely as
possible (before fund expenses) the total return of the Index.

          Investment Approach

         The Portfolio is appropriate for investors who seek a return comparable
to that of the U.S.  stock market as a whole as  represented  by the Index.  The
Index,  an  unmanaged  capitalization-weighted  index of over 7,000 U.S.  equity
securities, consists of all the U.S. stocks regularly traded on the New York and
American Stock Exchanges and the Nasdaq  over-the-counter  market. The Index has
been  computed  continuously  since  1974 and is  published  daily in many major
newspapers.

         The Portfolio  will invest  primarily in the common stocks of companies
included in the Index,  that Wilshire deems  representative of the entire Index,
selected on the basis of  computer  generated  statistical  data.  Although  the
Portfolio  will not hold  securities  of all the issuers  whose  securities  are
included in the Index,  it will normally hold  securities  representing at least
90% of the total market value of the Index.

         The  Portfolio  is  managed  through  the  use of a  "quantitative"  or
"indexing"  investment  approach,  which  attempts to duplicate  the  investment
composition and performance of the Index (before the deduction of fund expenses)
through  statistical  procedures.  As a  result,  the  Adviser  does not  employ
traditional methods of fund investment management,  such as selecting securities
on the basis of economic, financial and market analysis. Securities are selected
based primarily on market capitalization and industry weightings.

         Wilshire will keep the Portfolio  invested in common stocks as fully as
practicable.  During ordinary market  conditions,  it anticipates that more than
95% of the  Portfolio's  assets will be so invested.  In  connection  with these
investments,   the  Portfolio  may  from  time  to  time  receive  dividends  or
distributions of other securities with equity characteristics, such as preferred
stocks, warrants,  rights and securities convertible into common stock; Wilshire
will determine whether it is in the best interest of the Portfolio to hold these
securities  or  dispose  of  them.  It is not  Wilshire's  intent  to use  other
securities,  whether issues of individual companies or derivative securities, to
enhance or modify the return of the  Portfolio.  Nor is it Wilshire's  intent to
actively manage the Portfolio's cash position for defensive  reasons.  From time
to time as the result of  unforeseen  market  conditions  or to  facilitate  the
handling of contributions or withdrawals,  Wilshire may purchase such securities
if in its  judgement  this is in the best  interest  of the  shareholders.  Such
positions  will be  limited  to an amount  necessary  to deal with the  specific
condition  at  hand  and  will  be  liquidated  as soon  as  Wilshire  deems  it
appropriate. In order to meet anticipated redemption requests, the Portfolio may
invest part or all of its assets in U.S. government  securities and high quality
(within the two highest rating  categories  assigned by a nationally  recognized
securities rating organization) U.S. dollar-denominated money market securities,
including  certificates  of deposit,  bankers'  acceptances,  commercial  paper,
short-term debt securities and repurchase agreements.



INVESTMENT CONSIDERATIONS AND RISKS

         General -- The  Portfolio's  net asset value is not fixed and should be
expected to fluctuate.  You should  consider the Portfolio as a supplement to an
overall  investment  program  and  should  invest  only  if you are  willing  to
undertake the risks involved.

         The  Portfolio  may be  appropriate  for  investors  who are willing to
endure stock market  fluctuations  in pursuit of  potentially  higher  long-term
returns.  The  Portfolio  invests  for growth  and does not  pursue  income as a
primary objective. Over time, stocks, although more volatile, have shown greater
growth potential than other types of securities.  In the shorter term,  however,
stock  prices can  fluctuate  dramatically  in response to market  factors.  The
Portfolio is intended to be a long-term  investment  vehicle and is not designed
to provide investors with a means of speculating on short-term market movements.

         Equity securities  fluctuate in value, often based on factors unrelated
to the  value of the  issuer of the  securities,  and such  fluctuations  can be
pronounced.  Changes in the value of the Portfolio's  investment securities will
result  in  changes  in the  value  of  the  Portfolio's  shares  and  thus  the
Portfolio's total return to investors.  See "Investment Objective and Management
Policies" in the Statement of Additional Information.

         Over time,  Wilshire expects the correlation between the performance of
the  Portfolio  and the  Index to be 0.95 or  higher  before  deduction  of fund
expenses. A correlation of 1.00 would indicate perfect correlation,  which would
be achieved  when the net asset value of the  Portfolio,  including the value of
its dividend and any capital gain distributions, increases or decreases in exact
proportion to changes in the Index.  The Portfolio's  ability to track the Index
may be affected by, among other things,  transaction  costs,  administration and
other expenses  incurred by the Portfolio,  changes in either the composition of
the Index or the assets of the Portfolio, and the timing and amount of Portfolio
contributions and withdrawals.  If for any reason the Portfolio does not achieve
a high correlation, the Company's Board of Directors will consider alternatives.

         Except as otherwise indicated,  the Portfolio's  investment  objectives
and  policies  are  not  fundamental  and  may be  changed  without  a  vote  of
shareholders.  There can be no assurance that the Portfolio's  objective will be
met.  See  "Investment  Objective  and  Management  Policies -- Policies" in the
Statement of Additional Information for a further discussion of certain risks.

         Borrowing  Money -- The Portfolio is permitted to borrow money only for
temporary or emergency (not leveraging)  purposes, in an amount up to 15% of the
value of its total assets  (including the amount  borrowed) valued at the lesser
of cost or market,  less  liabilities (not including the amount borrowed) at the
time the borrowing is made. While borrowings  exceed 5% of the Portfolio's total
assets, the Portfolio will not purchase any additional securities.

         Simultaneous  Investments -- Investment decisions for the Portfolio are
made independently  from those of other series of the Company,  other investment
companies  and other  accounts  advised  by  Wilshire.  However,  if such  other
investment companies or accounts are prepared to invest in, or desire to dispose
of,  securities of the type in which the Portfolio  invests at approximately the
same time as the Portfolio,  available  investments or  opportunities  for sales
will be allocated equitably to each. In some cases, this procedure may adversely
affect the size of the position  obtained for or disposed of by the Portfolio or
the price paid or received by the Portfolio.

         Lending Portfolio  Securities -- The Portfolio may lend securities from
its  portfolio  to  brokers,  dealers  and  other  financial  institutions.   In
connection with such loans,  the Portfolio  continues to be entitled to payments
in amounts equal to the interest,  dividends or other  distributions  payable on
the loaned  securities.  Loans of portfolio  securities  afford the Portfolio an
opportunity  to earn  interest on the amount of the loan and at the same time to
earn income on the loan collateral. Loans of portfolio securities may not exceed
33 1/3% of the value of the  Portfolio's  total assets.  In connection with such
loans, the Portfolio will receive collateral consisting of cash, U.S. government
securities  or  irrevocable  letters of credit which will be  maintained  at all
times in an amount  equal to at least 100% of the  current  market  value of the
loaned  securities.  Such loans are terminable by the Portfolio at any time upon
specified notice. The Portfolio might experience risk of loss if the institution
with which it has engaged in a portfolio loan transaction breaches its agreement
with the Portfolio and the Portfolio is delayed or prevented from recovering the
collateral or completing the transaction.

         Year 2000 -- The  date-related  computer issues known as the "Year 2000
problem" could have an adverse impact on the quality of services provided to the
Company and its  shareholders.  However,  the Company  understands  that its key
service providers, including Wilshire, are taking steps to address the issue. In
addition,  the Year 2000 problem may  adversely  affect the issuers in which the
Portfolio  invests.  However,  because  the  objective  of the  Portfolio  is to
replicate as closely as possible  the total  return of the Wilshire  5000 Index,
Wilshire  does not perform  fundamental  analyses of the  companies in which the
Portfolio invests,  and does not attempt to monitor the impact of the problem on

         Investment  Adviser -- Wilshire,  located at 1299 Ocean  Avenue,  Santa
Monica,  California  90401,  was  formed in 1972 and  serves as the  Portfolio's
investment adviser.  As of October 1, 1998, Wilshire managed  approximately $7.4
billion  in  assets.  Under  the  terms  of the  Investment  Advisory  Agreement
described  below,  Wilshire,  subject to the overall  authority of the Company's
Board of Directors in accordance  with Maryland law,  manages the  investment of
the assets of the Portfolio. The Portfolio's primary portfolio manager is Thomas
D. Stevens,  the President and Chairman of the Board of Directors of the Company
and a Senior Vice President of Wilshire.  He has been employed by Wilshire since
1980. The Portfolio's  other portfolio manager is identified in the Statement of
Additional  Information.  Wilshire  also  provides  research  services  for  the
Portfolio  through a  professional  staff of portfolio  managers and  securities
analysts.  Wilshire is  controlled  by its  President,  Dennis Tito,  who owns a
majority of its outstanding voting stock.

         Pursuant to the terms of an Investment Advisory Agreement with Wilshire
(the  "Advisory  Agreement"),  the  Company  has  agreed to pay  Wilshire  a fee
computed  daily and paid  monthly at the annual rate of .10% of the value of the
Portfolio's  average  daily net assets.  Wilshire  will waive  advisory fees and
reimburse  other expenses with respect to the Portfolio to the extent  necessary
to maintain the Portfolio's  expense ratio (other than Rule 12b-1 fees) at 0.35%
of the Portfolio's average daily net assets until at least December 31, 1999.

         Administrator  -- Investor  Services  Group, a subsidiary of First Data
Corporation,  4400 Computer Drive,  Westborough,  Massachusetts 01581, serves as
the Company's  administrator  pursuant to an  Administration  Agreement with the
Company.  Under the terms of the  Administration  Agreement,  Investor  Services
Group generally assists in all aspects of the Company's  operations,  other than
providing  investment advice,  subject to the overall authority of the Company's
Board of Directors in accordance with Maryland law. Pursuant to the terms of the
Administration  Agreement, the Company has agreed to pay Investor Services Group
a fee,  computed daily and paid monthly,  at the annual rate of .15 of 1% of the
value of the Company's  monthly average net assets up to aggregate  assets of $1
billion,  .10 of 1% of the Company's  monthly  average net assets on the next $4
billion,  and .08 of 1% the Company's  monthly  average net assets on the excess
net assets.  In addition,  the Company has agreed to pay Investor Services Group
an annual fee of $25,000 per series and $2,000 for each additional class.

         Custodian  and Transfer and Dividend  Disbursing  Agent -- The Northern
Trust  Company,  50  South  LaSalle  Street,  Chicago,  Illinois  60675,  is the
custodian of the  Company's  investments.  Investor  Services  Group is also the
Company's Transfer and Dividend Disbursing Agent (the "Transfer Agent").

         Distributor -- FDDI,  4400 Computer Drive,  Westborough,  Massachusetts
01581,  serves as the distributor of the Company's  shares.  FDDI is an indirect
wholly-owned  subsidiary of First Data Corporation.  FDDI is not compensated for
its services as distributor.

Expenses -- From time to time,  Wilshire or  Investor  Services  Group may waive
receipt of its fees and/or  voluntarily assume certain expenses of the Portfolio
or the  Company,  which  would have the effect of lowering  the overall  expense
ratio of the Portfolio and  increasing  the return to investors at the time such
amounts  are waived or  assumed,  as the case may be. The  Company  will not pay
Wilshire  or  Investor  Services  Group for any  amounts  which may be waived or
assumed.  Each of FDDI,  Wilshire  or  Investor  Services  Group may bear  other
expenses of  distribution  of the shares of the Portfolio or of the provision of
shareholder  services to the  Portfolio's  shareholders,  including  payments to
securities dealers or other financial  intermediaries or service providers,  out
of  its  profits  and   available   resources   other  than  the   advisory  and
administration fees paid by the Company.

         All expenses  incurred in the operation of the Company are borne by the
Company, except to the extent specifically assumed by FDDI, Wilshire or Investor
Services Group. The expenses borne by the Company include: organizational costs;
taxes; interest;  brokerage fees and commissions,  if any; fees of Directors who
are  not  officers,  directors,  employees  or  holders  of 5% or  more  of  the
outstanding  voting  securities of FDDI,  Wilshire or Investor Services Group or
any of their affiliates;  SEC fees; state Blue Sky qualification  fees; advisory
and administration fees; charges of custodians, transfer and dividend disbursing
agents' fees;  certain insurance  premiums;  industry  association fees; outside
auditing and legal expenses; costs of maintaining the Company's existence; costs
of  independent  pricing  services;  costs  attributable  to  investor  services
(including,  without  limitation,  telephone and personnel  expenses);  costs of
shareholders' reports and meetings; costs of preparing and printing prospectuses
and  statements  of  additional  information  for  regulatory  purposes  and for
distribution to existing shareholders;  and any extraordinary expenses. Expenses
attributable  to a particular  series or class of shares are charged against the
assets of that series or class.  Other  expenses  of the  Company are  allocated
among the Portfolio  and other series of the Company on the basis  determined by
the Board of  Directors,  including,  but not  limited  to,  proportionately  in
relation to the net assets of the Portfolio and other series of the Company.



HOW TO BUY PORTFOLIO SHARES

         Shares are sold without a sales charge. You may be charged a fee if you
effect  transactions  in  shares  through  a  securities  dealer,  bank or other
financial  institution.  Share  certificates  are issued only upon your  written
request.  No certificates are issued for fractional shares. The Company reserves
the right to reject any purchase order.

         The minimum initial  investment in the Portfolio is $1,000.  Subsequent
investments must be at least $100. The initial investment must be accompanied by
the Account  Application.  The Company reserves the right to offer shares of the
Portfolio   without  regard  to  minimum  purchase   requirements  to  employees
participating in certain  qualified or  non-qualified  employee benefit plans or
other programs where  contributions or account information can be transmitted in
a manner and form acceptable to the Company.  The Company  reserves the right to
vary further the initial and subsequent  investment minimum  requirements at any
time. For investors who purchase through a financial intermediary and hold their
shares through an omnibus account with that financial intermediary,  the minimum
initial  investment  applies to the omnibus  account,  and not to the  investors
individually.



<PAGE>


         You may purchase shares by check or wire. Checks should be made payable
to "Wilshire  Target Funds,  Inc." For  subsequent  investments,  your Portfolio
account  number should appear on the check.  Payments which are mailed should be
sent  to  Wilshire  Target  Funds,  Inc.,  P.O.  Box  60488,  King  of  Prussia,
Pennsylvania  19406-0488,  together with your investment slip or, when opening a
new account,  your Account  Application,  indicating  the name of the Portfolio.
Neither initial nor subsequent investments may be made by third party check.

         Wire payments may be made if your bank account is in a commercial  bank
that is a member  of the  Federal  Reserve  System or any  other  bank  having a
correspondent  bank  in  New  York  City.  Immediately  available  funds  may be
transmitted  by wire to Boston Safe Deposit and Trust Company (ABA  #011001234),
together with the name of the Portfolio and the Portfolio's DDA number, 065-587,
for  purchase  of shares in your  name.  The wire must  include  your  Portfolio
account number (for new accounts,  your Taxpayer  Identification  Number ("TIN")
should  be  included  instead),  account  registration  and  dealer  number,  if
applicable. If your initial purchase of Portfolio shares is by wire, please call
1-888-200-6796  after  completing  your wire  payment to obtain  your  Portfolio
account  number.  Please  include your  Portfolio  account number on the Account
Application  and promptly mail the Account  Application to the Portfolio,  as no
redemptions will be permitted until the Account Application is received. You may
obtain further  information about remitting funds in this manner from your bank.
All  payments  should be made in U.S.  dollars  and,  to avoid fees and  delays,
should be drawn only on U.S.  banks.  A charge will be imposed if any check used
for investment in your account does not clear.  The Portfolio makes available to
certain large  institutions the ability to issue purchase  instructions  through
compatible computer facilities.

         Shares  also  may  be  purchased  through  the  Wilshire  Target  Funds
Accumulation Plan, described under "Shareholder  Services." This service enables
you  to  make  regularly  scheduled  investments  and  may  provide  you  with a
convenient  way to invest for long-term  financial  goals.  You should be aware,
however,  that periodic  investment plans do not guarantee a profit and will not
protect an investor against loss in a declining market.

         Subsequent investments also may be made by electronic transfer of funds
from an account  maintained in a bank or other  domestic  financial  institution
that is an Automated  Clearing House member.  You must direct the institution to
transmit immediately available funds through the Automated Clearing House to:

                                    Boston Safe Deposit and Trust Company
                                    Wilshire 5000 Index Portfolio
                                    (Shareholder Account Number)
                                    Account of (Registered Shareholder)

         Shares of the Portfolio are sold on a continuous basis at the net asset
value per share next determined after an order in proper form is received by the
Transfer Agent.  Net asset value per share of each class of shares is determined
as of the close of trading on the floor of the New York Stock Exchange (normally
4:00 p.m.,  New York time),  on each day the New York Stock Exchange is open for
business. For purposes of determining net asset value of the Portfolio,  futures
contracts  will be valued 15 minutes  after the close of trading on the floor of
the New York Stock  Exchange.  Net asset value per share of a class of shares of
the  Portfolio is computed by dividing the value of the net assets  attributable
to that  class of shares  (i.e.,  the value of the assets  attributable  to that
class less liabilities attributable to that class) by the total number of shares
of that class  outstanding.  The  Portfolio's  investments  are valued  based on
market value or, where market  quotations  are not readily  available,  based on
fair value as determined  in good faith by the Board of  Directors.  For further
information regarding the methods employed in valuing Portfolio investments, see
"Determination of Net Asset Value" in the Statement of Additional Information.

         Federal  regulations  require  that you  provide a  certified  TIN upon
opening or reopening an account.  See "Dividends,  Distributions  and Taxes" and
the Account  Application for further  information  concerning this  requirement.
Failure to furnish a certified TIN could subject you to a $50 penalty imposed by
the Internal Revenue Service (the "IRS").



SHAREHOLDER SERVICES

         Exchanges -- You may purchase, in exchange for shares of the Portfolio,
shares  of the same  class of one of the other  series  offered  by the  Company
(each,  a "Fund") or shares of another  class of the Portfolio or a Fund, to the
extent such shares are offered for sale in your state of residence  and you meet
the eligibility  requirements  (including  minimum  investment  amounts) for the
purchase of such shares.

         To request an  exchange,  you must give  exchange  instructions  to the
Transfer  Agent in writing.  The shares being  exchanged must have a value of at
least the applicable minimum initial investment, if any, required for the series
and class into which the exchange is being made.  The ability to issue  exchange
instructions by telephone is given to all shareholders automatically, unless you
check the applicable  "No" box on the Account  Application,  indicating that you
specifically  refuse this  privilege.  You may establish the Telephone  Exchange
Privilege for an existing account by written request, signed by all shareholders
on  the  account,  or by a  separate  signed  Shareholder  Services  Form,  also
available  by calling  1-888-200-6796.  If you have  established  the  Telephone
Exchange  Privilege,   you  may  telephone  exchange   instructions  by  calling
1-888-200-6796.  See  "How  to  Redeem  Portfolio  Shares-Procedures."  Upon  an
exchange into a new account, the following  shareholder services and privileges,
as applicable and where  available,  will be  automatically  carried over to the
Fund  into  which the  exchange  is made:  Telephone  Exchange  Privilege,  Wire
Redemption  Privilege,  Telephone  Redemption  Privilege,  and the  dividend and
capital gain distribution option you have selected.

         Shares will be exchanged at their next  determined net asset value.  No
fees  currently  are  charged  to  shareholders   directly  in  connection  with
exchanges,  although the Company reserves the right, upon not less than 60 days'
written  notice,  to charge  shareholders a nominal fee in accordance with rules
promulgated  by the SEC.  The Company  reserves the right to reject any exchange
request in whole or in part.  The  availability  of exchanges may be modified or
terminated at any time upon notice to shareholders.

         The exchange of shares of the Portfolio for shares of a Fund is treated
for Federal income tax purposes as a sale of the Portfolio  shares  exchanged by
the shareholder and, therefore, you may realize a taxable gain or loss.

         Money Market Fund -- You may also exchange  shares of the Portfolio for
shares of a money market fund. Please call 1-888-200-6796 to obtain a prospectus
and more information on how to exchange into the money market fund.

         Wilshire  Target  Funds  Accumulation  Plan --  Wilshire  Target  Funds
Accumulation Plan permits you to purchase  Portfolio shares (minimum of $100 and
maximum of $150,000 per transaction) at regular intervals you select. Shares are
purchased by  transferring  funds from the bank account you  designate.  At your
option,  the bank account will be debited in the  specified  amount,  and shares
will be purchased,  once a month, on either the first or fifteenth day, or twice
a month,  on both  days.  You may only  designate  an  account  maintained  at a
domestic  financial  institution which is an Automated Clearing House member. To
establish a Wilshire Target Funds  Accumulation  Plan account,  you must file an
authorization  form  with the  Transfer  Agent.  You may  obtain  the  necessary
authorization form by calling 1-888-200-6796.  You may cancel your participation
in this  privilege  or change  the  amount of  purchase  at any time by  mailing
written  notification  to Wilshire Target Funds,  Inc., P.O. Box 60488,  King of
Prussia,  Pennsylvania 19406-0488,  and the notification will be effective three
business  days  following  receipt.  The  Company may modify or  terminate  this
privilege  at any time or  charge  a  service  fee.  No such  fee  currently  is
contemplated.

         Retirement  Plans  -- The  Company  offers a  variety  of  pension  and
profit-sharing plans,  including Keogh Plans, IRAs, SEP-IRAs,  Roth IRAs and IRA
"Rollover  Accounts"  and  403(b)(7)  Plans.  Plan  support  services  also  are
available.  To obtain details on such Plans, please call the following toll-free
number: 1-888-200-6796.



HOW TO REDEEM PORTFOLIO SHARES

         General  -- You may  request  redemption  of your  shares  at any time.
Redemption  requests  should be  transmitted  in accordance  with the procedures
described  below.  When a request is received in proper form, the Portfolio will
redeem the shares at the next determined net asset value.

         Securities dealers, banks and other financial institutions may charge a
nominal  fee  for  effecting   redemptions  of  the  Portfolio's   shares.   Any
certificates   representing  the  Portfolio's  shares  being  redeemed  must  be
submitted with the redemption  request.  The value of the shares redeemed may be
more  or  less  than  their  original  cost,   depending  upon  the  Portfolio's
then-current net asset value.

         The  Portfolio  ordinarily  will make  payment for all shares  redeemed
within seven days after receipt by the Transfer Agent of a redemption request in
proper form, except as provided by the rules of the SEC.

         However,  if you have  purchased  the  Portfolio's  shares  by check or
through the Wilshire Target Funds  Accumulation  Plan and subsequently  submit a
written redemption  request to the Transfer Agent, the redemption  proceeds will
be  transmitted  to you promptly upon bank  clearance of your purchase  check or
Wilshire  Target Funds  Accumulation  Plan order,  which may take eight business
days or more. In addition,  the Portfolio will reject  requests to redeem shares
by wire or telephone  for a period of eight  business  days after receipt by the
Transfer Agent of the purchase check or the Wilshire  Target Funds  Accumulation
Plan order against which such redemption is requested. These procedures will not
apply if your shares were purchased by wire payment,  or if you otherwise have a
sufficient  collected  balance in your account to cover the redemption  request.
Prior to the time any  redemption  is  effective,  dividends on such shares will
accrue and be payable,  and you will be entitled to exercise all other rights of
beneficial ownership.

         The  Transfer  Agent will not redeem your shares  until it has received
your Account Application.

         The  Portfolio  reserves the right to redeem your account at its option
upon not less than 45 days' written  notice if your account's net asset value is
$500 or less as a result of redemptions and remains so during the notice period.

         Procedures  -- You may redeem  shares by using the  regular  redemption
procedure  through the Transfer  Agent,  or, if you have checked the appropriate
box and supplied the necessary  information  on the Account  Application or have
filed a  Shareholder  Services  Form with the Transfer  Agent,  through the Wire
Redemption Privilege or the Telephone Redemption Privilege. The Company reserves
the right to refuse any request made by wire or  telephone,  including  requests
made shortly after a change of address, and may limit the amount involved or the
number of such  requests.  The Company may modify or  terminate  any  redemption
privilege  at any time or charge a service fee upon notice to  shareholders.  No
such fee currently is contemplated.

         You may redeem shares by telephone if you have checked the  appropriate
box on the Account  Application  or have filed a Shareholder  Services Form with
the Transfer Agent. If you select a Telephone  Redemption Privilege or Telephone
Exchange  Privilege (which is granted  automatically  unless you refuse it), you
authorize the Transfer  Agent to act on telephone  instructions  from any person
representing  himself  or  herself  to be you  and  reasonably  believed  by the
Transfer  Agent to be genuine.  The Company will  require the Transfer  Agent to
employ   reasonable   procedures,   such  as   requiring   a  form  of  personal
identification,  to confirm  that  instructions  are genuine and, if it does not
follow such procedures,  the Company or the Transfer Agent may be liable for any
losses due to unauthorized or fraudulent  instructions.  Neither the Company nor
the  Transfer  Agent  will  be  liable  for  following  telephone   instructions
reasonably believed to be genuine.

         During  times  of  drastic  economic  or  market  conditions,  you  may
experience difficulty in contacting the Transfer Agent by telephone to request a
redemption  or exchange of the  Portfolio's  shares.  In such cases,  you should
consider using the other redemption  procedures  described herein.  Use of these
other  redemption  procedures  may  result  in  your  redemption  request  being
processed  at a later time than it would have been if telephone  redemption  had
been used. During the delay, the Portfolio's net asset value may fluctuate.



<PAGE>


         Regular Redemption -- Under the regular redemption  procedure,  you may
redeem your shares by written  request  mailed to Wilshire  Target Funds,  Inc.,
P.O. Box 60488, King of Prussia,  Pennsylvania  19406-0488.  Redemption requests
must be signed by each shareholder, including each owner of a joint account, and
each signature must be guaranteed.  The Transfer Agent has adopted standards and
procedures pursuant to which  signature-guarantees in proper form generally will
be accepted from domestic  banks,  brokers,  dealers,  credit  unions,  national
securities exchanges, registered securities associations,  clearing agencies and
savings  associations,  as well  as from  participants  in the  New  York  Stock
Exchange Medallion  Signature Program,  the Securities Transfer Agents Medallion
Program ("STAMP"),  and the Stock Exchanges  Medallion Program.  If you have any
questions with respect to signature-guarantees, please call one of the telephone
numbers listed under "General Information."

     Redemption  proceeds of at least $1,000 will be wired to any member bank of
the Federal  Reserve  System in accordance  with a written  signature-guaranteed
request.

         Wire Redemption  Privilege -- You may request by wire or telephone that
redemption proceeds (minimum $1,000) be wired to your account at a bank which is
a member of the Federal Reserve System, or a correspondent  bank if your bank is
not a member.  You also may direct  that  redemption  proceeds  be paid by check
(maximum  $150,000  per day) made out to the owners of record and mailed to your
address.  Redemption  proceeds of less than $1,000 will be paid automatically by
check. Holders of jointly registered accounts may have redemption proceeds of up
to $250,000 wired within any 30-day period. You may make redemption  requests by
calling  1-888-200-6796.  The  Statement of  Additional  Information  sets forth
instructions for  transmitting  redemption  requests by wire.  Shares held under
Keogh Plans, IRAs or other retirement  plans, and shares for which  certificates
have been issued, are not eligible for this privilege.

         Telephone  Redemption  Privilege -- You may request by  telephone  that
redemption  proceeds  (maximum  $150,000 per day) be paid by check and mailed to
your   address.   You  may   telephone   redemption   instructions   by  calling
1-888-200-6796.  Shares held under Keogh Plans,  IRAs or other retirement plans,
and shares for which  certificates  have been issued,  are not eligible for this
privilege.



SERVICE AND DISTRIBUTION PLAN

         The  Directors of the Company  have adopted a service and  distribution
plan (the "Service and Distribution  Plan") with respect to the Investment Class
shares of the Portfolio pursuant to Section 12(b) of the 1940 Act and Rule 12b-1
thereunder.  Under the Service and  Distribution  Plan,  the Company  reimburses
FDDI,  distributor  of the Company,  at an annual rate of up to .25 of 1% of the
value of the  average  daily net assets  attributable  to the  Investment  Class
shares of the Portfolio for certain service and distribution  expenses borne, or
paid to others, by FDDI.  Generally,  the service fees covered under the Service
and  Distribution  Plan are fees paid to securities  dealers and other financial
intermediaries  for personal  services to holders of the Investment Class shares
of the Portfolio  and/or for the  maintenance  of the accounts of the holders of
the Investment Class shares. The services provided may include personal services
relating  to  shareholder  accounts,  such as  answering  shareholder  inquiries
regarding the Company and providing reports and other information,  and services
related to the  maintenance  of  shareholder  accounts.  To the extent that such
service fees do not  aggregate  .25 of 1% of the value of the average  daily net
assets attributable to the Investment class shares of the Portfolio, the Service
and  Distribution  Plan also permits  reimbursement  for  distribution  expenses
borne,  or paid to others,  by FDDI for the purpose of financing or assisting in
the financing of any activity which is primarily  intended to result in the sale
of the  Investment  Class  shares of the  Portfolio.  The types of  distribution
expenses  covered  include,  but are not limited  to, the costs and  expenses of
direct marketing activities  (including related travel, meals and lodging);  the
design,  preparation,   printing  and  distribution  of  promotional  materials,
advertising and offering materials,  and shareholder materials; the compensation
of securities  dealers and other financial  intermediaries for sales activities;
and related capital,  overhead and interest expenses.  Amounts payable under the
Service and  Distribution  Plan  relating to the  Portfolio  are charged to, and
therefore  reduce,  income  allocated  to the  Investment  Class  shares  of the
Portfolio.



DIVIDENDS, DISTRIBUTIONS AND TAXES

         The Portfolio  ordinarily  declares and distributes net realized gains,
if any, once a year,  but may make  distributions  on a more  frequent  basis to
comply with the distribution  requirements of the Internal Revenue Code of 1986,
as  amended  (the  "Code"),  in all  events  in a  manner  consistent  with  the
provisions  of the 1940 Act.  The Company will not make  distributions  from net
realized  gains unless  capital loss  carryovers,  if any, have been utilized or
have expired.  You may choose whether to receive  dividends and distributions in
cash or to reinvest in  additional  shares at net asset value.  All expenses are
accrued daily and deducted before declaration of dividends to investors.

         The  Portfolio  intends  to  distribute  substantially  all of its  net
investment  income  and  net  realized  securities  gains  on a  current  basis.
Dividends  paid  by  the  Portfolio  derived  from  net  investment  income  and
distributions  from net realized  short-term  securities  gains of the Portfolio
will be taxable to U.S.  shareholders  as ordinary income for federal income tax
purposes whether received in cash or reinvested in additional shares.  Depending
upon  the  composition  of  the  Portfolio's  income,  all or a  portion  of the
dividends  derived  from net  investment  income may qualify  for the  dividends
received deduction  allowable to certain U.S.  corporations.  Distributions from
net realized long-term securities gains of the Portfolio will be taxable to U.S.
shareholders  as  long-term  capital  gains for  Federal  income  tax  purposes,
regardless  of how long  shareholders  have held their  shares and whether  such
distributions are received in cash or reinvested in shares.  The maximum federal
capital gains rate for  individuals  is 28% with respect to capital  assets held
for more than 12 months,  but not more than 18 months,  and 20% with  respect to
capital  assets  held more than 18 months.  The maximum  capital  gains rate for
corporate shareholders is the same as the maximum tax rate for ordinary income.
Dividends and distributions will generally be subject to state and local taxes.

         Dividends  from  net  investment  income  and  distributions  from  net
realized short-term securities gains paid by the Portfolio to a foreign investor
generally are subject to U.S. nonresident  withholding taxes at the rate of 30%,
unless the  foreign  investor  is  entitled to claim the benefit of a lower rate
specified in a tax treaty.  Distributions from net realized long-term securities
gains paid by the Portfolio to a foreign investor as well as the proceeds of any

<PAGE>


redemptions from a foreign investor's account, regardless of the extent to which
gain  or loss  may be  realized,  generally  will  not be  subject  to any  U.S.
withholding tax.  However,  such  distributions  and redemption  proceeds may be
subject to backup  withholding,  as described below, unless the foreign investor
certifies his or her non-U.S.  residency status. The tax consequences to foreign
investors engaged in a trade or business that is effectively  connected with the
United States may differ from the foregoing.

         Notice as to the tax status of your dividends and distributions will be
mailed to you annually. You also will receive periodic summaries of your account
which will include information as to dividends and distributions from securities
gains, if any, paid during the year.

         Federal regulations  generally require the Company to withhold ("backup
withholding")  and remit to the U.S.  Treasury 31% of  dividends,  distributions
from  net  realized  securities  gains  and  the  proceeds  of  any  redemption,
regardless  of the extent to which gain or loss may be realized,  paid to you if
you fail to certify either that the TIN furnished in connection  with opening an
account is correct or that you have not  received  notice  from the IRS of being
subject  to  backup  withholding  as a result of a failure  to  properly  report
taxable dividend or interest income on a Federal income tax return. Furthermore,
the IRS may notify the  Portfolio to  institute  backup  withholding  if the IRS
determines  your TIN is  incorrect or if you failed to properly  report  taxable
dividend and interest income on a Federal income tax return.

         A TIN is either the Social Security  number or employer  identification
number of the  record  owner of the  account.  Any tax  withheld  as a result of
backup  withholding  does not constitute an additional tax imposed on the record
owner of the  account,  and may be  claimed  as a credit on the  record  owner's
Federal income tax return.

         The Portfolio  intends to qualify as a "regulated  investment  company"
under the Code. Such  qualification  relieves the Portfolio of any liability for
Federal income tax to the extent its earnings are distributed in accordance with
applicable  provisions of the Code. In addition, a 4% non-deductible  excise tax
is imposed on regulated  investment  companies that fail to currently distribute
specified  percentages  of their  ordinary  income and  capital  gain net income
(excess of capital gains over capital  losses).  The  Portfolio  intends to make
sufficient  distributions or deemed distributions of its ordinary income and any
capital  gain net income with respect to each year to avoid  liability  for this
excise tax.

         The  foregoing  is a general  summary  of the U.S.  Federal  income tax
consequences of investing in the Portfolio.  You should consult your tax adviser
regarding specific questions as to Federal, state or local taxes.



PERFORMANCE INFORMATION

         For purposes of advertising, performance may be calculated on the basis
of average annual total returns  and/or total returns of the  Portfolio.  "Total
return" is the change in value of an investment in the Portfolio for a specified
period. The "average annual total return" of the Portfolio is the average annual
compound  rate  of  return  on an  investment  in  the  Portfolio  assuming  the
investment  has been held for one-,  five- and ten year  periods (or the life of
the Portfolio if shorter).

         Performance  will  vary  from  time to time  and past  results  are not
necessarily   representative  of  future  results.   You  should  remember  that
performance  is a function  of  portfolio  management  and is also  affected  by
operating  expenses,  market  conditions  and  the  risks  associated  with  the
Portfolio's objective and investment policies.  Performance information, such as
that  described  above,  may not  provide  a basis  for  comparison  with  other
investments  or  other   investment   companies  using  a  different  method  of
calculating performance.

   Comparative  performance  information  may be  used  from  time  to  time  in
advertising  or marketing the shares of the  Portfolio,  including data from the
Wilshire 5000 Index, Lipper Analytical Services, Inc., the Standard & Poor's 500
Composite Stock Price Index, the Dow Jones Industrial Average, Morningstar, Inc.
and other industry publications.



GENERAL INFORMATION

         The Company was  incorporated  under Maryland law on July 30, 1992, and
commenced  operations on September 30, 1992.  The Company is authorized to issue
600 million shares of Common Stock (with 100 million  allocated to the Portfolio
and 50 million  allocated to each class of the  Portfolio),  par value $.001 per
share.

         The Company is a "series  fund,"  which is a mutual fund  divided  into
separate series.  Each series of the Company is treated as a separate entity for
certain matters under the 1940 Act and for other purposes.  A shareholder of one
series is not  deemed to be a  shareholder  of any other  series.  As  described
below, for certain matters  shareholders of all series vote together as a group;
as to others they vote separately by series or by class.

         To date the Board of  Directors  has  authorized  the  creation of five
series of shares and an "Investment Class" and  "Institutional  Class" of shares
for each series. All consideration  received by the Company for shares of one of
the series and all assets in which such consideration is invested will belong to
that series (subject only to the rights of creditors of that series) and will be
subject to the liabilities  related  thereto.  Each share of a class of a series
represents an equal  proportionate  interest in the series with each other class
share,  subject to the liabilities of the particular class. Each class of shares
of  a  series  participates  equally  in  the  earnings,  dividends  and  assets
attributable to that class. The income attributable to, and the expenses of, one
class are treated  separately from those of the other classes.  Shares are fully
paid and  non-assessable.  Should a series be  liquidated,  the  holders of each
class are  entitled  to share pro rata in the net  assets  attributable  to that
class available for distribution to shareholders. The Board of Directors has the
ability to create,  from time to time, new series and additional classes without
shareholder approval. Shares have no pre-emptive or conversion rights.

         Institutional  Class  shares,  which are  generally  available  only to
institutions investing at least $5 million in the Portfolio,  bear no Rule 12b-1
fee  and,   consequently,   the  Company  expects  the  investment   returns  of
Institutional  Class shares to exceed those of Investment Class shares. For more
information regarding  eligibility to purchase  Institutional Class shares, call
1-888-200-6796 or contact your investment representative.

         Unless  otherwise  required by the 1940 Act,  ordinarily it will not be
necessary for the Company to hold annual meetings of shareholders.  As a result,
shareholders  may not  consider  each  year the  election  of  Directors  or the
appointment of auditors. However, pursuant to the Company's By-Laws, the holders
of at least 10% of the shares  outstanding  and entitled to vote may require the
Company to hold a special meeting of shareholders for the purpose of considering
the removal of a Director from office or for any other purpose. Shareholders may
remove  a  Director  by the  affirmative  vote of a  majority  of the  Company's
outstanding  voting  shares.  In addition,  the Board of  Directors  will call a
meeting of shareholders  for the purpose of electing  Directors if, at any time,
less than a majority of the Directors  then holding  office have been elected by
shareholders.  Each share has one vote and shares of each series are entitled to
vote  separately  to  approve  investment  advisory  agreements  or  changes  in
investment restrictions,  but shares of all series vote together in the election
of  Directors  or  selection  of  accountants.  Each  class of a series  is also
entitled to vote  separately  on any  material  increases  in the fees under its
Service and  Distribution  Plan or on any other matter that affects  solely that
class of shares,  but will  otherwise  vote  together  with all other classes of
shares of the series on all other matters on which  shareholders are entitled to
vote.

         The  Transfer  Agent  maintains  a record of your  ownership  and sends
confirmations  and  statements of account.  Certificates  for Shares will not be
issued unless specifically requested.

         Shareholder  inquiries  may be made by writing to the Fund at P.O.  Box
60488,  King of  Prussia,  Pennsylvania  19406-0488,  or by  calling  toll  free
1-888-200-6796.

         No person has been  authorized to give any  information  or to make any
representations  other  than  those  contained  in  this  prospectus  and in the
Company's  official  sales  literature  in  connection  with  the  offer  of the
Portfolio's   shares,   and,  if  given  or  made,  such  other  information  or
representations  must  not be  relied  upon as  having  been  authorized  by the

DESCRIPTION OF THE PORTFOLIO

         Investment Objective

         The goal of the  Wilshire  5000  Index  Portfolio  is to  replicate  as
closely as possible (before fund expenses) the total return of the Index.

          Investment Approach

         The Portfolio is appropriate for investors who seek a return comparable
to that of the U.S.  stock market as a whole as  represented  by the Index.  The
Index,  an  unmanaged  capitalization-weighted  index of over 7,000 U.S.  equity
securities,  which consists of all the U.S. stocks  regularly  traded on the New
York and American Stock Exchanges and the Nasdaq  over-the-counter  market.  The
Index has been computed  continuously  since 1974 and is published daily in many
newspapers.

         The Portfolio  will invest  primarily in the common stocks of companies
included in the Index,  that Wilshire deems  representative of the entire Index,
selected on the basis of  computer  generated  statistical  data.  Although  the
Portfolio  will not hold  securities  of all the issuers  whose  securities  are
included in the Index,  it will normally hold  securities  representing at least
90% of the total market value of the Index.

         The  Portfolio  is  managed  through  the  use of a  "quantitative"  or
"indexing"  investment  approach,  which  attempts to duplicate  the  investment
composition and performance of the Index (before the deduction of fund expenses)
through  statistical  procedures.  As a  result,  the  Adviser  does not  employ
traditional methods of fund investment management,  such as selecting securities
on the basis of economic, financial and market analysis. Securities are selected
based primarily on market capitalization and industry weightings.

         Wilshire will keep the Portfolio  invested in common stocks as fully as
practicable.  During ordinary market  conditions,  it anticipates that more than
95% of the  Portfolio's  assets will be so invested.  In  connection  with these
investments,   the  Portfolio  may  from  time  to  time  receive  dividends  or
distributions of other securities with equity characteristics, such as preferred
stocks, warrants,  rights and securities convertible into common stock; Wilshire
will determine whether it is in the best interest of the Portfolio to hold these
securities  or  dispose  of  them.  It is not  Wilshire's  intent  to use  other
securities,  whether issues of individual companies or derivative securities, to
enhance or modify the return of the  Portfolio.  Nor is it Wilshire's  intent to
actively manage the Portfolio's cash position for defensive  reasons.  From time
to time as the result of  unforeseen  market  conditions  or to  facilitate  the
handling of contributions or withdrawals,  Wilshire may purchase such securities
if in its  judgment  this is in the  best  interest  of the  shareholders.  Such
positions  will be  limited  to an amount  necessary  to deal with the  specific
condition  at  hand  and  will  be  liquidated  as soon  as  Wilshire  deems  it
appropriate.  In order to meet anticipated redemption,  the Portfolio may invest
part or all of its assets in U.S. government securities and high quality (within
the two highest rating categories assigned by a nationally recognized securities
rating organization) U.S. dollar-denominated money market securities,  including
certificates of deposit, bankers' acceptances, commercial paper, short-term debt
securities and repurchase agreements.



INVESTMENT CONSIDERATIONS AND RISKS

         General -- The  Portfolio's  net asset value is not fixed and should be
expected to fluctuate.  You should  consider the Portfolio as a supplement to an
overall  investment  program  and  should  invest  only  if you are  willing  to
undertake the risks involved.

         The  Portfolio  may be  appropriate  for  investors  who are willing to
endure stock market  fluctuations  in pursuit of  potentially  higher  long-term
returns.  The  Portfolio  invests  for growth  and does not  pursue  income as a
primary objective. Over time, stocks, although more volatile, have shown greater
growth potential than other types of securities.  In the shorter term,  however,
stock  prices can  fluctuate  dramatically  in response to market  factors.  The
Portfolio is intended to be a long-term  investment  vehicle and is not designed
to provide investors with a means of speculating on short-term market movements.

         Equity securities  fluctuate in value, often based on factors unrelated
to the  value of the  issuer of the  securities,  and such  fluctuations  can be
pronounced.  Changes in the value of the Portfolio's  investment securities will
result  in  changes  in the  value  of  the  Portfolio's  shares  and  thus  the
Portfolio's total return to investors.  See "Investment Objective and Management
Policies" in the Statement of Additional Information.

         Over time,  Wilshire expects the correlation between the performance of
the  Portfolio  and the  Index to be 0.95 or  higher  before  deduction  of fund
expenses. A correlation of 1.00 would indicate perfect correlation,  which would
be achieved  when the net asset value of the  Portfolio,  including the value of
its dividend and any capital gain distributions, increases or decreases in exact
proportion to changes in the Index.  The Portfolio's  ability to track the Index
may be affected by, among other things,  transaction  costs,  administration and
other expenses  incurred by the Portfolio,  changes in either the composition of
the Index or the assets of the Portfolio, and the timing and amount of Portfolio
contributions and withdrawals.  If for any reason the Portfolio does not achieve
a high correlation, the Company's Board of Directors will consider alternatives.



<PAGE>


         Except as otherwise indicated,  the Portfolio's  investment  objectives
and  policies  are  not  fundamental  and  may be  changed  without  a  vote  of
shareholders.  There can be no assurance that the Portfolio's  objective will be
met.  See  "Investment  Objective  and  Management  Policies -- Policies" in the
Statement of Additional Information for a further discussion of certain risks.

         Borrowing  Money -- The Portfolio is permitted to borrow money only for
temporary or emergency (not leveraging)  purposes, in an amount up to 15% of the
value of its total assets  (including the amount  borrowed) valued at the lesser
of cost or market,  less  liabilities (not including the amount borrowed) at the
time the borrowing is made. While borrowings  exceed 5% of the Portfolio's total
assets, the Portfolio will not purchase any additional securities.

         Simultaneous  Investments -- Investment decisions for the Portfolio are
made independently  from those of other series of the Company,  other investment
companies  and other  accounts  advised  by  Wilshire.  However,  if such  other
investment companies or accounts are prepared to invest in, or desire to dispose
of,  securities of the type in which the Portfolio  invests at approximately the
same time as the Portfolio,  available  investments or  opportunities  for sales
will be allocated equitably to each. In some cases, this procedure may adversely
affect the size of the position  obtained for or disposed of by the Portfolio or
the price paid or received by the Portfolio.

         Lending Portfolio  Securities -- The Portfolio may lend securities from
its  portfolio  to  brokers,  dealers  and  other  financial  institutions.   In
connection with such loans,  the Portfolio  continues to be entitled to payments
in amounts equal to the interest,  dividends or other  distributions  payable on
the loaned  securities.  Loans of portfolio  securities  afford the Portfolio an
opportunity  to earn  interest on the amount of the loan and at the same time to
earn income on the loan collateral. Loans of portfolio securities may not exceed
33 1/3% of the value of the  Portfolio's  total assets.  In connection with such
loans, the Portfolio will receive collateral consisting of cash, U.S. government
securities  or  irrevocable  letters of credit which will be  maintained  at all
times in an amount  equal to at least 100% of the  current  market  value of the
loaned collateral securities.  Such loans are terminable by the Portfolio at any
time upon specified  notice.  The Portfolio might experience risk of loss if the
institution with which it has engaged in a portfolio loan  transaction  breaches
its agreement  with the Portfolio and the Portfolio is delayed or prevented from
recovering the collateral or completing the transaction.

         Year 2000 - The  date-related  computer  issues known as the "Year 2000
problem" could have an adverse impact on the quality of services provided to the
Company and its  shareholders.  However,  the Company  understands  that its key
service providers, including Wilshire, are taking steps to address the issue. In
addition,  the Year 2000 problem may  adversely  affect the issuers in which the
Portfolio  invests.  However,  because  the  objective  of the  Portfolio  is to
replicate as closely as possible  the total  return of the Wilshire  5000 Index,
Wilshire  does not perform  fundamental  analyses of the  companies in which the
Portfolio invests,  and does not attempt to monitor the impact of the problem on
individual issuers.

MANAGEMENT OF THE PORTFOLIO

         Investment  Adviser -- Wilshire,  located at 1299 Ocean  Avenue,  Santa
Monica,  California  90401,  was  formed in 1972 and  serves as the  Portfolio's
investment adviser.  As of October 1, 1998, Wilshire managed  approximately $7.4
billion  in  assets.  Under  the  terms  of the  Investment  Advisory  Agreement
described  below,  Wilshire,  subject to the overall  authority of the Company's
Board of Directors in accordance  with Maryland law,  manages the  investment of
the assets of the Portfolio. The Portfolio's primary portfolio manager is Thomas
D. Stevens,  the President and Chairman of the Board of Directors of the Company
and a Senior Vice President of Wilshire.  He has been employed by Wilshire since
1980. The Portfolio's  other portfolio manager is identified in the Statement of
Additional  Information.  Wilshire  also  provides  research  services  for  the
Portfolio  through a  professional  staff of portfolio  managers and  securities
analysts.  Wilshire is  controlled  by its  President,  Dennis Tito,  who owns a
majority of its outstanding voting stock.

         Pursuant to the terms of an Investment Advisory Agreement with Wilshire
(the  "Advisory  Agreement"),  the  Company  has  agreed to pay  Wilshire  a fee
computed  daily and paid  monthly at the annual rate of .10% of the value of the
Portfolio's  average  daily net assets.  Wilshire  will waive  advisory fees and
reimburse  other expenses with respect to the Portfolio to the extent  necessary
to maintain the Portfolio's  expense ratio at 0.35% of the  Portfolio's  average
daily net assets until at least December 31, 1999.

         Administrator  -- Investor  Services  Group, a subsidiary of First Data
Corporation,  4400 Computer Drive,  Westborough,  Massachusetts 01581, serves as
the Company's  administrator  pursuant to an  Administration  Agreement with the
Company.  Under the terms of the  Administration  Agreement,  Investor  Services
Group generally assists in all aspects of the Company's  operations,  other than
providing  investment advice,  subject to the overall authority of the Company's
Board of Directors in accordance with Maryland law. Pursuant to the terms of the
Administration  Agreement, the Company has agreed to pay Investor Services Group
a fee,  computed daily and paid monthly,  at the annual rate of .15 of 1% of the
value of the Company's  monthly average net assets up to aggregate  assets of $1
billion,  .10 of 1% of the Company's  monthly  average net assets on the next $4
billion,  and .08 of 1% the Company's  monthly  average net assets on the excess
net assets.  In addition,  the Company has agreed to pay Investor Services Group
an annual fee of $25,000 per series and $2,000 for each additional class.

         Custodian  and Transfer and Dividend  Disbursing  Agent -- The Northern
Trust  Company,  50  South  LaSalle  Street,  Chicago,  Illinois  60675,  is the
custodian of the  Company's  investments.  Investor  Services  Group is also the
Company's Transfer and Dividend Disbursing Agent (the "Transfer Agent").

         Distributor -- FDDI,  4400 Computer Drive,  Westborough,  Massachusetts
01581,  serves as the distributor of the Company's  shares.  FDDI is an indirect
wholly-owned  subsidiary of First Data Corporation.  FDDI is not compensated for
its services as distributor.



<PAGE>


         Expenses -- From time to time,  Wilshire or Investor Services Group may
waive  receipt of its fees and/or  voluntarily  assume  certain  expenses of the
Portfolio  or the  Company,  which would have the effect of lowering the overall
expense  ratio of the Portfolio  and  increasing  the return to investors at the
time such  amounts are waived or assumed,  as the case may be. The Company  will
not pay Wilshire or Investor  Services Group for any amounts which may be waived
or assumed.  Each of FDDI,  Wilshire or Investor  Services  Group may bear other
expenses of  distribution  of the shares of the Portfolio or of the provision of
shareholder  services to the  Portfolio's  shareholders,  including  payments to
securities dealers or other financial  intermediaries or service providers,  out
of  its  profits  and   available   resources   other  than  the   advisory  and
administration fees paid by the Company.

         All expenses  incurred in the operation of the Company are borne by the
Company, except to the extent specifically assumed by FDDI, Wilshire or Investor
Services Group. The expenses borne by the Company include: organizational costs;
taxes; interest;  brokerage fees and commissions;  if any, fees of Directors who
are  not  officers,  directors,  employees  or  holders  of 5% or  more  of  the
outstanding  voting  securities of FDDI,  Wilshire or Investor Services Group or
any of their affiliates;  SEC fees; state Blue Sky qualification  fees; advisory
and administration fees; charges of custodians, transfer and dividend disbursing
agents' fees;  certain insurance  premiums;  industry  association fees; outside
auditing and legal expenses; costs of maintaining the Company's existence; costs
of  independent  pricing  services;  costs  attributable  to  investor  services
(including,  without  limitation,  telephone and personnel  expenses);  costs of
shareholders' reports and meetings; costs of preparing and printing prospectuses
and  statements  of  additional  information  for  regulatory  purposes  and for
distribution to existing shareholders;  and any extraordinary expenses. Expenses
attributable  to a particular  series or class of shares are charged against the
assets of that series or class.  Other  expenses  of the  Company are  allocated
among the Portfolio  and other series of the Company on the basis  determined by
the Board of  Directors,  including,  but not  limited  to,  proportionately  in
relation to the net assets of the Portfolio and other series of the Company.



HOW TO BUY PORTFOLIO SHARES

         Shares are sold without a sales charge. You may be charged a fee if you
effect  transactions  in  shares  through  a  securities  dealer,  bank or other
financial  institution.  Share  certificates  are issued only upon your  written
request.  No certificates are issued for fractional shares. The Company reserves
the right to reject any purchase order.

         The  minimum  initial   investment  in  the  Portfolio  is  $5,000,000.
Subsequent investments must be at least $100,000. The initial investment must be
accompanied by the Account  Application.  The Company reserves the right to vary
further the initial and subsequent  investment minimum requirements at any time.
For  investors  who  purchase  through a financial  intermediary  and hold their
shares through an omnibus account with that financial intermediary,  the minimum
initial  investment  applies to the omnibus  account,  and not to the  investors
individually.

         You may purchase shares by check or wire. Checks should be made payable
to "Wilshire  Target Funds,  Inc." For  subsequent  investments,  your Portfolio
account  number should appear on the check.  Payments which are mailed should be
sent  to  Wilshire  Target  Funds,  Inc.,  P.O.  Box  60488,  King  of  Prussia,
Pennsylvania  19406-0488,  together with your investment slip or, when opening a
new account,  your Account  Application,  indicating  the name of the Portfolio.
Neither initial nor subsequent investments may be made by third party check.

         Wire payments may be made if your bank account is in a commercial  bank
that is a member  of the  Federal  Reserve  System or any  other  bank  having a
correspondent  bank  in  New  York  City.  Immediately  available  funds  may be
transmitted  by wire to Boston Safe Deposit and Trust Company (ABA  #011001234),
together with the name of the Portfolio and the Portfolio's DDA number, 065-587,
for  purchase  of shares in your  name.  The wire must  include  your  Portfolio
account number (for new accounts,  your Taxpayer  Identification  Number ("TIN")
should  be  included  instead),  account  registration  and  dealer  number,  if
applicable. If your initial purchase of Portfolio shares is by wire, please call
1-888-200-6796  after  completing  your wire  payment to obtain  your  Portfolio
account  number.  Please  include your  Portfolio  account number on the Account
Application  and promptly mail the Account  Application to the Portfolio,  as no
redemptions will be permitted until the Account Application is received. You may
obtain further  information about remitting funds in this manner from your bank.
All  payments  should be made in U.S.  dollars  and,  to avoid fees and  delays,
should be drawn only on U.S.  banks.  A charge will be imposed if any check used
for investment in your account does not clear.  The Portfolio makes available to
certain large  institutions the ability to issue purchase  instructions  through
compatible computer facilities.

         Subsequent investments also may be made by electronic transfer of funds
from an account  maintained in a bank or other  domestic  financial  institution
that is an Automated  Clearing House member.  You must direct the institution to
transmit immediately available funds through the Automated Clearing House to:

         Boston Safe Deposit and Trust Company
         Wilshire 5000 Index Portfolio
         (Shareholder Account Number)
         Account of (Registered Shareholder)

         Shares of the Portfolio are sold on a continuous basis at the net asset
value per share next determined after an order in proper form is received by the
Transfer Agent.  Net asset value per share of each class of shares is determined
as of the close of trading on the floor of the New York Stock Exchange (normally
4:00 p.m.,  New York time),  on each day the New York Stock Exchange is open for
business. For purposes of determining net asset value of the Portfolio,  futures
contracts  will be valued 15 minutes  after the close of trading on the floor of
the New York Stock  Exchange.  Net asset value per share of a class of shares of
the  Portfolio is computed by dividing the value of the net assets  attributable
to that  class of shares  (i.e.,  the value of the assets  attributable  to that
class less liabilities attributable to that class) by the total number of shares
of that class  outstanding.  The  Portfolio's  investments  are valued  based on
market value or, where market  quotations  are not readily  available,  based on
fair value as determined  in good faith by the Board of  Directors.  For further
information regarding the methods employed in valuing Portfolio investments, see
"Determination of Net Asset Value" in the Statement of Additional Information.

         Federal  regulations  require  that you  provide a  certified  TIN upon
opening or reopening an account.  See "Dividends,  Distributions  and Taxes" and
the Account  Application for further  information  concerning this  requirement.
Failure to furnish a certified TIN could subject you to a $50 penalty imposed by
the Internal Revenue Service (the "IRS").



SHAREHOLDER SERVICES

         Exchanges -- You may purchase, in exchange for shares of the Portfolio,
shares  of the same  class of one of the other  series  offered  by the  Company
(each,  a "Fund") or shares of another  class of the Portfolio or a Fund, to the
extent such shares are offered for sale in your state of residence  and you meet
the eligibility  requirements  (including  minimum  investment  amounts) for the
purchase of such shares.

         To request an  exchange,  you must give  exchange  instructions  to the
Transfer  Agent in writing.  The shares being  exchanged must have a value of at
least the applicable minimum initial investment, if any, required for the series
and class into which the exchange is being made.  The ability to issue  exchange
instructions by telephone is given to all shareholders automatically, unless you
check the applicable  "No" box on the Account  Application,  indicating that you
specifically  refuse this  privilege.  You may establish the Telephone  Exchange
Privilege for an existing account by written request, signed by all shareholders
on  the  account,  or by a  separate  signed  Shareholder  Services  Form,  also
available  by calling  1-888-200-6796.  If you have  established  the  Telephone
Exchange  Privilege,   you  may  telephone  exchange   instructions  by  calling
1-888-200-6796.  See  "How  to  Redeem  Portfolio  Shares-Procedures."  Upon  an
exchange into a new account, the following  shareholder services and privileges,
as applicable and where  available,  will be  automatically  carried over to the
Fund  into  which the  exchange  is made:  Telephone  Exchange  Privilege,  Wire
Redemption  Privilege,  Telephone  Redemption  Privilege,  and the  dividend and
capital gain distribution option you have selected.

         Shares will be exchanged at their next  determined net asset value.  No
fees  currently  are  charged  to  shareholders   directly  in  connection  with
exchanges,  although the Company reserves the right, upon not less than 60 days'
written  notice,  to charge  shareholders a nominal fee in accordance with rules
promulgated  by the SEC.  The Company  reserves the right to reject any exchange
request in whole or in part.  The  availability  of exchanges may be modified or
terminated at any time upon notice to shareholders.

         The exchange of shares of the Portfolio for shares of a Fund is treated
for Federal income tax purposes as a sale of the Portfolio  shares  exchanged by
the shareholder and, therefore, you may realize a taxable gain or loss.

         Money  Market  Fund -- You may  also  exchange  shares  of the Fund for
shares of a money market fund. Please call 1-888-200-6796 to obtain a prospectus
and more information on how to exchange into the money market fund.



<PAGE>


         Retirement  Plans  -- The  Company  offers a  variety  of  pension  and
profit-sharing plans,  including Keogh Plans, IRAs, SEP-IRAs,  Roth IRAs and IRA
"Rollover  Accounts"  and  403(b)(7)  Plans.  Plan  support  services  also  are
available.  To obtain details on such Plans, please call the following toll-free
number: 1-888-200-6796.



HOW TO REDEEM PORTFOLIO SHARES

         General  -- You may  request  redemption  of your  shares  at any time.
Redemption  requests  should be  transmitted  in accordance  with the procedures
described  below.  When a request is received in proper form, the Portfolio will
redeem the shares at the next determined net asset value.

         Securities dealers, banks and other financial institutions may charge a
nominal  fee  for  effecting   redemptions  of  the  Portfolio's   shares.   Any
certificates   representing  the  Portfolio's  shares  being  redeemed  must  be
submitted with the redemption  request.  The value of the shares redeemed may be
more  or  less  than  their  original  cost,   depending  upon  the  Portfolio's
then-current net asset value.

         The  Portfolio  ordinarily  will make  payment for all shares  redeemed
within seven days after receipt by the Transfer Agent of a redemption request in
proper form, except as provided by the rules of the SEC.

         However,  if you have  purchased  the  Portfolio's  shares  by check or
through the Wilshire Target Funds  Accumulation  Plan and subsequently  submit a
written redemption  request to the Transfer Agent, the redemption  proceeds will
be  transmitted  to you promptly upon bank  clearance of your purchase  check or
Wilshire  Target Funds  Accumulation  Plan order,  which may take eight business
days or more. In addition,  the Portfolio will reject  requests to redeem shares
by wire or telephone  for a period of eight  business  days after receipt by the
Transfer Agent of the purchase check or the Wilshire  Target Funds  Accumulation
Plan order against which such redemption is requested. These procedures will not
apply if your shares were purchased by wire payment,  or if you otherwise have a
sufficient  collected  balance in your account to cover the redemption  request.
Prior to the time any  redemption  is  effective,  dividends on such shares will
accrue and be payable,  and you will be entitled to exercise all other rights of
beneficial ownership.

         The  Transfer  Agent will not redeem your shares  until it has received
your Account Application.

         The  Portfolio  reserves the right to redeem your account at its option
upon not less than 45 days' written  notice if your account's net asset value is
$500 or less as a result of redemptions and remains so during the notice period.



<PAGE>


         Procedures  -- You may redeem  shares by using the  regular  redemption
procedure  through the Transfer  Agent,  or, if you have checked the appropriate
box and supplied the necessary  information  on the Account  Application or have
filed a  Shareholder  Services  Form with the Transfer  Agent,  through the Wire
Redemption Privilege or the Telephone Redemption Privilege. The Company reserves
the right to refuse any request made by wire or  telephone,  including  requests
made shortly after a change of address, and may limit the amount involved or the
number of such  requests.  The Company may modify or  terminate  any  redemption
privilege  at any time or charge a service fee upon notice to  shareholders.  No
such fee currently is contemplated.

         You may redeem shares by telephone if you have checked the  appropriate
box on the Account  Application  or have filed a Shareholder  Services Form with
the Transfer Agent. If you select a Telephone  Redemption Privilege or Telephone
Exchange  Privilege (which is granted  automatically  unless you refuse it), you
authorize the Transfer  Agent to act on telephone  instructions  from any person
representing  himself  or  herself  to be you  and  reasonably  believed  by the
Transfer  Agent to be genuine.  The Company will  require the Transfer  Agent to
employ   reasonable   procedures,   such  as   requiring   a  form  of  personal
identification,  to confirm  that  instructions  are genuine and, if it does not
follow such procedures,  the Company or the Transfer Agent may be liable for any
losses due to unauthorized or fraudulent  instructions.  Neither the Company nor
the  Transfer  Agent  will  be  liable  for  following  telephone   instructions
reasonably believed to be genuine.

         During  times  of  drastic  economic  or  market  conditions,  you  may
experience difficulty in contacting the Transfer Agent by telephone to request a
redemption  or exchange of the  Portfolio's  shares.  In such cases,  you should
consider using the other redemption  procedures  described herein.  Use of these
other  redemption  procedures  may  result  in  your  redemption  request  being
processed  at a later time than it would have been if telephone  redemption  had
been used. During the delay, the Portfolio's net asset value may fluctuate.

         Regular Redemption -- Under the regular redemption  procedure,  you may
redeem your shares by written  request  mailed to Wilshire  Target Funds,  Inc.,
P.O. Box 60488, King of Prussia,  Pennsylvania  19406-0488.  Redemption requests
must be signed by each shareholder, including each owner of a joint account, and
each signature must be guaranteed.  The Transfer Agent has adopted standards and
procedures pursuant to which  signature-guarantees in proper form generally will
be accepted from domestic  banks,  brokers,  dealers,  credit  unions,  national
securities exchanges, registered securities associations,  clearing agencies and
savings  associations,  as well  as from  participants  in the  New  York  Stock
Exchange Medallion  Signature Program,  the Securities Transfer Agents Medallion
Program ("STAMP"),  and the Stock Exchanges  Medallion Program.  If you have any
questions with respect to signature-guarantees, please call one of the telephone
numbers listed under "General Information."

         Redemption proceeds of at least $1,000 will be wired to any member bank
of the Federal Reserve System in accordance with a written  signature-guaranteed
request.



<PAGE>


         Wire Redemption  Privilege -- You may request by wire or telephone that
redemption proceeds (minimum $1,000) be wired to your account at a bank which is
a member of the Federal Reserve System, or a correspondent  bank if your bank is
not a member.  You also may direct  that  redemption  proceeds  be paid by check
(maximum  $150,000  per day) made out to the owners of record and mailed to your
address.  Redemption  proceeds of less than $1,000 will be paid automatically by
check. Holders of jointly registered accounts may have redemption proceeds of up
to $250,000 wired within any 30-day period. You may make redemption  requests by
calling  1-888-200-6796.  The  Statement of  Additional  Information  sets forth
instructions for  transmitting  redemption  requests by wire.  Shares held under
Keogh Plans, IRAs or other retirement  plans, and shares for which  certificates
have been issued, are not eligible for this privilege.

         Telephone  Redemption  Privilege -- You may request by  telephone  that
redemption  proceeds  (maximum  $150,000 per day) be paid by check and mailed to
your   address.   You  may   telephone   redemption   instructions   by  calling
1-888-200-6796.  Shares held under Keogh Plans,  IRAs or other retirement plans,
and shares for which  certificates  have been issued,  are not eligible for this
privilege.



DIVIDENDS, DISTRIBUTIONS AND TAXES

         The Portfolio  ordinarily  declares and distributes net realized gains,
if any, once a year,  but may make  distributions  on a more  frequent  basis to
comply with the distribution  requirements of the Internal Revenue Code of 1986,
as  amended  (the  "Code"),  in all  events  in a  manner  consistent  with  the
provisions  of the 1940 Act.  The Company will not make  distributions  from net
realized  gains unless  capital loss  carryovers,  if any, have been utilized or
have expired.  You may choose whether to receive  dividends and distributions in
cash or to reinvest in  additional  shares at net asset value.  All expenses are
accrued daily and deducted before declaration of dividends to investors.

         The  Portfolio  intends  to  distribute  substantially  all of its  net
investment  income  and  net  realized  securities  gains  on a  current  basis.
Dividends  paid  by  the  Portfolio  derived  from  net  investment  income  and
distributions  from net realized  short-term  securities  gains of the Portfolio
will be taxable to U.S.  shareholders  as ordinary income for federal income tax
purposes whether received in cash or reinvested in additional shares.  Depending
upon  the  composition  of  the  Portfolio's  income,  all or a  portion  of the
dividends  derived  from net  investment  income may qualify  for the  dividends
received deduction  allowable to certain U.S.  corporations.  Distributions from
net realized long-term securities gains of the Portfolio will be taxable to U.S.
shareholders  as  long-term  capital  gains for  Federal  income  tax  purposes,
regardless  of how long  shareholders  have held their  shares and whether  such
distributions are received in cash or reinvested in shares.  The maximum federal
capital gains rate for  individuals  is 28% with respect to capital  assets held
for more than 12 months,  but not more than 18 months,  and 20% with  respect to
capital  assets  held more than 18 months.  The maximum  capital  gains rate for
corporate  shareholders is the same as the maximum tax rate for ordinary income.
Dividends and distributions will generally be subject to state and local taxes.



<PAGE>


         Dividends  from  net  investment  income  and  distributions  from  net
realized short-term securities gains paid by the Portfolio to a foreign investor
generally are subject to U.S. nonresident  withholding taxes at the rate of 30%,
unless the  foreign  investor  is  entitled to claim the benefit of a lower rate
specified in a tax treaty.  Distributions from net realized long-term securities
gains paid by the Portfolio to a foreign investor as well as the proceeds of any
redemptions from a foreign investor's account, regardless of the extent to which
gain  or loss  may be  realized,  generally  will  not be  subject  to any  U.S.
withholding tax.  However,  such  distributions  and redemption  proceeds may be
subject to backup  withholding,  as described below, unless the foreign investor
certifies his or her non-U.S.  residency status. The tax consequences to foreign
investors engaged in a trade or business that is effectively  connected with the
United States may differ from the foregoing.

         Notice as to the tax status of your dividends and distributions will be
mailed to you annually. You also will receive periodic summaries of your account
which will include information as to dividends and distributions from securities
gains, if any, paid during the year.

         Federal regulations  generally require the Company to withhold ("backup
withholding")  and remit to the U.S.  Treasury 31% of  dividends,  distributions
from  net  realized  securities  gains  and  the  proceeds  of  any  redemption,
regardless  of the extent to which gain or loss may be realized,  paid to you if
you fail to certify either that the TIN furnished in connection  with opening an
account is correct or that you have not  received  notice  from the IRS of being
subject  to  backup  withholding  as a result of a failure  to  properly  report
taxable dividend or interest income on a Federal income tax return. Furthermore,
the IRS may notify the  Portfolio to  institute  backup  withholding  if the IRS
determines  your TIN is  incorrect  or if you have  failed  to  properly  report
taxable dividend and interest income on a Federal income tax return.

         A TIN is either the Social Security  number or employer  identification
number of the  record  owner of the  account.  Any tax  withheld  as a result of
backup  withholding  does not constitute an additional tax imposed on the record
owner of the  account,  and may be  claimed  as a credit on the  record  owner's
Federal income tax return.

         The Portfolio  intends to qualify as a "regulated  investment  company"
under the Code. Such  qualification  relieves the Portfolio of any liability for
Federal income tax to the extent its earnings are distributed in accordance with
applicable  provisions of the Code. In addition, a 4% non-deductible  excise tax
is imposed on regulated  investment  companies that fail to currently distribute
specified  percentages  of their  ordinary  income and  capital  gain net income
(excess of capital gains over capital  losses).  The  Portfolio  intends to make
sufficient  distributions or deemed distributions of its ordinary income and any
capital  gain net income with respect to each year to avoid  liability  for this
excise tax.

         The  foregoing  is a general  summary  of the U.S.  Federal  income tax
consequences of investing in the Portfolio.  You should consult your tax adviser
regarding specific questions as to Federal, state or local taxes.

PERFORMANCE INFORMATION

         For purposes of advertising, performance may be calculated on the basis
of average annual total returns  and/or total returns of the  Portfolio.  "Total
return" is the change in value of an investment in the Portfolio for a specified
period. The "average annual total return" of the Portfolio is the average annual
compound  rate  of  return  on an  investment  in  the  Portfolio  assuming  the
investment  has been held for one-,  five- and ten year  periods (or the life of
the Portfolio if shorter).

         Performance  will  vary  from  time to time  and past  results  are not
necessarily   representative  of  future  results.   You  should  remember  that
performance  is a function  of  portfolio  management  and is also  affected  by
operating  expenses,  market  conditions  and  the  risks  associated  with  the
Portfolio's objective and investment policies.  Performance information, such as
that  described  above,  may not  provide  a basis  for  comparison  with  other
investments  or  other   investment   companies  using  a  different  method  of
calculating performance.

         Comparative  performance  information  may be used from time to time in
advertising  or marketing the shares of the  Portfolio,  including data from the
Wilshire 5000 Index, Lipper Analytical Services, Inc., the Standard & Poor's 500
Composite Stock Price Index, the Dow Jones Industrial Average, Morningstar, Inc.
and other industry publications.



GENERAL INFORMATION

         The Company was  incorporated  under Maryland law on July 30, 1992, and
commenced  operations on September 30, 1992.  The Company is authorized to issue
600 million shares of Common Stock (with 100 million  allocated to the Portfolio
and 50 million  allocated to each class of the  Portfolio),  par value $.001 per
share.

         The Company is a "series  fund,"  which is a mutual fund  divided  into
separate series.  Each series of the Company is treated as a separate entity for
certain matters under the 1940 Act and for other purposes.  A shareholder of one
series is not  deemed to be a  shareholder  of any other  series.  As  described
below, for certain matters  shareholders of all series vote together as a group;
as to others they vote separately by series or by class.

         To date,  the Board of Directors  has  authorized  the creation of five
series of shares and an "Investment Class" and  "Institutional  Class" of shares
for each series. All consideration  received by the Company for shares of one of
the series and all assets in which such consideration is invested will belong to
that series (subject only to the rights of creditors of that series) and will be
subject to the liabilities  related  thereto.  Each share of a class of a series
represents an equal  proportionate  interest in the series with each other class
share,  subject to the liabilities of the particular class. Each class of shares
of  a  series  participates  equally  in  the  earnings,  dividends  and  assets
attributable to that class. The income attributable to, and the expenses of, one
class are treated  separately from those of the other classes.  Shares are fully
paid and  non-assessable.  Should a series be  liquidated,  the  holders of each
class are  entitled  to share pro rata in the net  assets  attributable  to that
class available for distribution to shareholders. The Board of Directors has the
ability to create,  from time to time, new series and additional classes without
shareholder approval. Shares have no pre-emptive or conversion rights.

         Investment Class shares,  which are generally  available to the public,
bear a Rule  12b-1  fee of up to .25% of the  average  daily  net  assets of the
Portfolio's  Investment Class shares.  For information  regarding the Investment
Class shares call 1-888-200-6796 or contact your investment representative.

         Unless  otherwise  required by the 1940 Act,  ordinarily it will not be
necessary for the Company to hold annual meetings of shareholders.  As a result,
shareholders  may not  consider  each  year the  election  of  Directors  or the
appointment of auditors. However, pursuant to the Company's By-Laws, the holders
of at least 10% of the shares  outstanding  and entitled to vote may require the
Company to hold a special meeting of shareholders for the purpose of considering
the removal of a Director from office or for any other purpose. Shareholders may
remove  a  Director  by the  affirmative  vote of a  majority  of the  Company's
outstanding  voting  shares.  In addition,  the Board of  Directors  will call a
meeting of shareholders  for the purpose of electing  Directors if, at any time,
less than a majority of the Directors  then holding  office have been elected by
shareholders.  Each share has one vote and shares of each series are entitled to
vote  separately  to  approve  investment  advisory  agreements  or  changes  in
investment restrictions,  but shares of all series vote together in the election
of  Directors  or  selection  of  accountants.  Each  class of a series  is also
entitled to vote  separately  on any  material  increases  in the fees under its
Services and  Distribution  Plan or on any other matter that affects solely that
class of shares,  but will  otherwise  vote  together  with all other classes of
shares of the series on all other matters on which  shareholders are entitled to
vote.

         The  Transfer  Agent  maintains  a record of your  ownership  and sends
confirmations  and  statements of account.  Certificates  for Shares will not be
issued unless specifically requested.

         Shareholder  inquiries  may be made by writing to the Fund at P.O.  Box
60488,  King of  Prussia,  Pennsylvania  19406-0488,  or by  calling  toll  free
1-888-200-6796.

         No person has been  authorized to give any  information  or to make any
representations  other  than  those  contained  in  this  prospectus  and in the
Company's  official sales  literature in connection with the offer of the Fund's
shares,  and, if given or made, such other information or  representations  must
not be relied upon as having been  authorized  by the Company.  This  prospectus
does not  constitute  an offer in any state in which,  or to any person to whom,
such offering may not lawfully be made.

OTHER PORTFOLIO SECURITIES

U.S.  GOVERNMENT  SECURITIES.  The Portfolio may purchase  securities  issued or
guaranteed by the U.S.  Government or its agencies or  instrumentalities,  which
include U.S. Treasury securities that differ in their interest rates, maturities
and times of issuance.  Some obligations issued or guaranteed by U.S. Government
agencies  and  instrumentalities,  for  example,  Government  National  Mortgage
Association  pass-through  certificates,  are  supported  by the full  faith and
credit of the U.S.  Treasury;  others,  such as those of the  Federal  Home Loan
Banks, by the right of the issuer to borrow from the Treasury;  others,  such as
those issued by the Federal  National  Mortgage  Association,  by  discretionary
authority of the U.S.  Government to purchase certain  obligations of the agency
or  instrumentality;  and  others,  such as those  issued  by the  Student  Loan
Marketing  Association,  only by the  credit of the  agency or  instrumentality.
These securities bear fixed,  floating or variable rates of interest.  While the
U.S.  Government  provides  financial support to such U.S.  Government-sponsored
agencies or instrumentalities,  no assurance can be given that it will always do
so, since it is not so obligated by law.

BANK  OBLIGATIONS.  The Portfolio  may purchase  certificates  of deposit,  time
deposits,  bankers'  acceptances  and  other  short-term  obligations  issued by
domestic banks,  foreign  subsidiaries of domestic  banks,  foreign  branches of
domestic  banks,  and domestic and foreign  branches of foreign banks,  domestic
savings and loan  associations and other banking  institutions.  With respect to
such  securities   issued  by  foreign  branches  of  domestic  banks,   foreign
subsidiaries  of domestic  banks,  and domestic and foreign  branches of foreign
banks,  the  Portfolio may be subject to  additional  investment  risks that are
different in some respects from those incurred by a portfolio which invests only
in debt obligations of U.S. domestic issuers. Such risks include possible future
political  and  economic  developments,   the  possible  imposition  of  foreign
withholding  taxes on interest  income payable on the  securities,  the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions  which might adversely affect the payment of principal and interest
on these  securities  and the  possible  seizure or  nationalization  of foreign
deposits.

Certificates of deposit are negotiable certificates evidencing the obligation of
a bank to repay funds deposited with it for a specified period of time.



<PAGE>


Time deposits are non-negotiable  deposits  maintained in a banking  institution
for a specified  period of time at a stated  interest  rate.  The Portfolio only
will only invest in time  deposits of domestic  banks that have total  assets in
excess of one billion dollars.  Time deposits which may be held by the Portfolio
will not benefit  from  insurance  from the Bank  Insurance  Fund or the Savings
Association  Insurance  Fund  administered  by  the  Federal  Deposit  Insurance
Corporation.

Bankers' acceptances are credit instruments  evidencing the obligation of a bank
to  pay a  draft  drawn  on it by a  customer.  These  instruments  reflect  the
obligation  both of the bank and of the  drawer  to pay the face  amount  of the
instrument upon maturity.  The other  short-term  bank  obligations in which the
Portfolio may invest may include uninsured,  direct  obligations  bearing fixed,
floating or variable interest rates.

REPURCHASE  AGREEMENTS.  In a repurchase agreement,  the Portfolio buys, and the
seller agrees to repurchase, a security at a mutually agreed upon time and price
(usually within seven days).  The repurchase  agreement  thereby  determines the
yield during the purchaser's  holding period,  while the seller's  obligation to
repurchase  is  secured  by the  value of the  underlying  security.  Repurchase
agreements  could  involve  risks in the event of a default or insolvency of the
other party to the agreement, including possible delays or restrictions upon the
Portfolio's  ability to  dispose of the  underlying  securities.  The  Company's
custodian or  sub-custodian  will have custody of, and will hold in a segregated
account,  securities  acquired by the  Portfolio  under a repurchase  agreement.
Repurchase  agreements are considered by the staff of the SEC to be loans by the
Portfolio.  In an attempt to reduce the risk of incurring a loss on a repurchase
agreement,  the  Portfolio  will  enter  into  repurchase  agreements  only with
domestic  banks with total assets in excess of one billion  dollars with respect
to securities  of the type in which the  Portfolio may invest,  and will require
that  additional  securities be deposited with it if the value of the securities
purchased should decrease below resale price.

LENDING  PORTFOLIO  SECURITIES.   In  connection  with  its  securities  lending
transactions, the Portfolio may return to the borrower or a third party which is
unaffiliated with the Company, and which is acting as a "placing broker," a part
of the interest earned from the investment of collateral received for securities
loaned.

The SEC currently  requires that the following  conditions  must be met whenever
portfolio  securities  are loaned:  (1) the Portfolio must receive at least 100%
cash  collateral  from  the  borrower;  (2)  the  borrower  must  increase  such
collateral  whenever the market value of the securities rises above the level of
such  collateral;  (3) the  Portfolio  must be able to terminate the loan at any
time; (4) the Portfolio must receive reasonable interest on the loan, as well as
any dividends, interest or other distributions payable on the loaned securities,
and any increase in market  value;  (5) the  Portfolio  may pay only  reasonable
custodian  fees in connection  with the loan; and (6) while voting rights on the
loaned  securities  may pass to the borrower,  the Company's  Board of Directors
must  terminate  the loan and  regain  the  right  to vote the  securities  if a
material event adversely  affecting the investment occurs.  These conditions may
be subject to future modification.

COMMERCIAL PAPER AND OTHER SHORT-TERM  CORPORATE  OBLIGATIONS.  Commercial paper
consists of short-term,  unsecured promissory notes issued to finance short-term
credit needs.  The commercial paper purchased by the Portfolio will consist only
of direct  obligations  which, at the time of their purchase,  are (a) rated not
lower than Prime-1 by Moody's Investors Service,  Inc., A-1 by Standard & Poor's
Ratings  Group,  F-1 by Fitch  Investors  Service,  L.P. or D-1 by Duff & Phelps
Credit Rating Co.; (b) issued by companies having an outstanding  unsecured debt
issue currently rated not lower than Aa3 by Moody's Investors  Service,  Inc. or
AA- by Standard & Poor's Ratings Group, Fitch Investors Service,  L.P. or Duff &
Phelps  Credit  Rating Co.; or (c) if unrated,  determined  by Wilshire to be of
comparable  quality to those rated  obligations  which may be  purchased  by the
Portfolio.  These instruments include variable amount master demand notes, which
are  obligations  that permit the  Portfolio  to invest  fluctuating  amounts at
varying rates of interest pursuant to direct arrangements between the Portfolio,
as lender,  and the  borrower.  These notes permit daily  changes in the amounts
borrowed.  Because these obligations are direct lending arrangements between the
lender and borrower, it is not contemplated that such instruments generally will
be traded,  and there  generally is no  established  secondary  market for these
obligations,  although they are redeemable at face value, plus accrued interest,
at any time. Accordingly,  where these obligations are not secured by letters of
credit or other credit support arrangements,  the Portfolio's right to redeem is
dependent  on the  ability of the  borrower  to pay  principal  and  interest on
demand.  In  connection  with  floating  and variable  rate demand  obligations,
Wilshire will consider,  on an ongoing basis, earning power, cash flow and other
liquidity  ratios of the borrower,  and the borrower's  ability to pay principal
and  interest on demand.  Such  obligations  frequently  are not rated by credit
rating agencies,  and the Portfolio may invest in them only if at the time of an
investment the borrower meets the criteria set forth above for other  commercial
paper issuers.

PREFERRED  STOCK.  The  Portfolio may invest up to 5% of its assets in preferred
stock.  Preferred  Stock,  unlike  common stock,  offers a stated  dividend rate
payable from a  corporation's  earnings.  Such preferred  stock dividends may be
cumulative or  non-cumulative,  participating or auction rate. If interest rates
rise, the fixed dividend on preferred stocks may be less attractive, causing the
price of preferred stocks to decline. Preferred stock may have mandatory sinking
fund provisions,  as well as  call/redemption  provisions  prior to maturity,  a
negative feature when interest rates decline.  Dividends on some preferred stock
may be "cumulative,"  requiring all or a portion of prior unpaid dividends to be
paid before  dividends are paid on the issuer's  common stock.  Preferred  stock
also  generally  has a  preference  over common stock on the  distribution  of a
corporation's assets in the event of liquidation of the corporation,  and may be
"participating," which means that it may be entitled to a dividend exceeding the
stated  dividend  in  certain  cases.  The  rights  of  preferred  stocks on the
distribution  of a  corporation's  assets  in the  event  of a  liquidation  are
generally  subordinate  to  the  rights  associated  with a  corporation's  debt
securities.

CONVERTIBLE  SECURITIES.  The  Portfolio  may  invest up to 5% of its  assets in
convertible  securities  when its appears to Wilshire that it may not be prudent
to be fully  invested in common  stocks.  In evaluating a convertible  security,
Wilshire places primary emphasis on the  attractiveness of the underlying common
stock and the potential for capital appreciation through conversion. Convertible
securities may include  corporate  notes or preferred stock but are ordinarily a
long-term debt  obligation of the issuer  convertible at a stated  exchange rate
into common stock of the issuer.  As with all debt securities,  the market value
of  convertible  securities  tends to decline as interest  rates  increase  and,
conversely,  to increase  as  interest  rates  decline.  Convertible  securities
generally  offer  lower  interest  or  dividend   yields  than   non-convertible
securities  of similar  quality.  However,  when the market  price of the common
stock underlying a convertible  security exceeds the conversion price, the price
of the convertible  security tends to reflect the value of the underlying common
stock.  As the  market  price  of the  underlying  common  stock  declines,  the
convertible  security tends to trade increasingly on a yield basis, and thus may
not  depreciate to the same extent as the underlying  common stock.  Convertible
securities rank senior to common stocks in an issuer's capital structure and are
consequently  of higher  quality and entail less risk than the  issuer's  common
stock,  although  the  extent to which  such risk is  reduced  depends  in large
measure upon the degree to which the convertible  security sells above its value
as a fixed income security.

WARRANTS AND RIGHTS. The Portfolio may invest up to 5% of its assets in warrants
and similar rights to purchase stock. Warrants basically are options to purchase
equity  securities  at a specified  price  valid for a specific  period of time.
Their prices do not  necessarily  move parallel to the prices of the  underlying
securities.  Rights are similar to warrants,  but normally have a short duration
and are  distributed  directly  by the  issuer to its  shareholders.  Rights and
warrants  have no voting  rights,  receive no dividends  and have no rights with
respect to the assets of the issuer.

DERIVATIVES.  Although  Wilshire has no current  intention  to invest  Portfolio
assets in financial  instruments  which derive  their  performance,  at least in
part, from the performance of an underlying assets or index ("Derivatives"),  it
reserves the right to do so in the future. Under normal market conditions,  less
than 5% of the net assets of the  Portfolio  would be invested  in  Derivatives.
Derivatives may provide a cheaper,  quicker or more specifically focused way for
the Portfolio to invest than "traditional" securities would.

Derivatives  can be  volatile  and  involve  various  types and degrees of risk,
depending  upon  the  characteristics  of  the  particular  Derivative  and  the
Portfolio as a whole. Derivatives permit the Portfolio to increase,  decrease or
change  the  level of risk to which  it is  exposed  in much the same way as the
Portfolio can  increase,  decrease or change its risk by making  investments  in
specific securities.

In addition,  Derivatives may entail investment  exposures that are greater than
their cost would suggest,  meaning that a small investment in Derivatives  could
have a large potential impact on the Portfolio's  performance.  If the Portfolio
invests  in  Derivatives  at  inappropriate  times or judges  market  conditions
incorrectly,  such  investments may lower the Portfolio's  return or result in a
loss. The Portfolio also could experience  losses if its Derivatives were poorly
correlated  with its  other  investments,  or if the  Portfolio  were  unable to
liquidate its position because of an illiquid  secondary market.  The market for
many Derivatives is, or suddenly can become, illiquid.  Changes in liquidity may
result in  significant,  rapid  and  unpredictable  changes  in the  prices  for
Derivatives.

When required by the SEC, the Portfolio will set aside permissible liquid assets
in a  segregated  account to cover its  obligations  relating to its purchase of
Derivatives.  To maintain  this required  cover,  the Portfolio may have to sell
portfolio  securities  at  disadvantageous  prices or times  since it may not be
possible to liquidate a Derivative  position at a reasonable price.  Derivatives
may be  purchased  on  established  exchanges  or through  privately  negotiated
transactions  referred  to  as  over-the-counter  Derivatives.   Exchange-traded
Derivatives  generally are guaranteed by the clearing agency which is the issuer
or counterparty to such  Derivatives.  This guarantee  usually is supported by a
daily payment system  operated by the clearing agency in order to reduce overall
credit  risk.  As a  result,  unless  the  clearing  agency  defaults,  there is
relatively little counterparty credit risk associated with Derivatives purchased
on an exchange.  By contrast,  no clearing  agency  guarantees  over-the-counter
Derivatives.  Therefore, each party to an over-the-counter  Derivative bears the
risk that the counterparty will default. Accordingly, Wilshire will consider the
creditworthiness of counterparties to  over-the-counter  Derivatives in the same
manner as it would  review the credit  quality of a security to be  purchased by
the Portfolio. Over-the-counter Derivatives are less liquid than exchange-traded
Derivatives  since the other party to the  transaction  may be the only investor
with sufficient  understanding of the Derivative to be interested in bidding for
it.

OPTIONS. The Portfolio may write covered call options, buy put options, buy call
options and write secured put options on  particular  securities or the Wilshire
5000 Index.  Options  trading is a highly  specialized  activity  which  entails
greater than ordinary  investment risks. A call option for a particular security
gives the purchaser of the option the right to buy, and a writer the  obligation
to sell, the underlying  security at the stated exercise price at any time prior
to the expiration of the option, regardless of the market price of the security.
The  premium  paid  to  the  writer  is in  consideration  for  undertaking  the
obligations  under the option contract.  A put option for a particular  security
gives the  purchaser  the right to sell the  underlying  security  at the stated
exercise  price  at  any  time  prior  to the  expiration  date  of the  option,
regardless of the market price of the security.

Options  on stock  indices  are  similar  to  options  on  specific  securities,
described above,  except that, rather than the right to take or make delivery of
the specific  security at a specific price, an option on a stock index gives the
holder the right to receive,  upon exercise of the option,  an amount of cash if
the  closing  level of that stock index is greater  than,  in the case of a call
option,  or less than,  in the case of a put option,  the exercise  price of the
option.  This  amount of cash is equal to such  difference  between  the closing
price of the index and the  exercise  price of the  option  expressed  in dollar
times a specified multiple. The writer of the option is obligated, in return for
the  premium  received,  to make  delivery  of this  amount.  Unlike  options on
specific  securities,  all  settlements of options on stock indices are in cash,
and gain or loss  depends on general  movements  in the stocks  included  in the
index rather than price movements in particular stock.

FUTURES  TRANSACTIONS.  The  Portfolio  may  enter  into  futures  contracts  or
particular  securities [or stock indices] in U.S. domestic markets,  such as the
Chicago  Board of Trade and the  International  Monetary  Market of the  Chicago
Mercantile  Exchange.  A futures  contract  is an  agreement  in which one party
agrees to  deliver  to the other an amount of cash  equal to a  specific  dollar
amount times the difference between the value of a specific stock or stock index
at the close of the last  trading day of the contract and the price at which the
agreement is made.
No physical delivery of securities is made.

Engaging in these  transactions  involves  risk of loss to the  Portfolio  which
could affect the value of the  Portfolio's  net assets  adversely.  Although the
Portfolio  intends to purchase  or sell  futures  contracts  only if there is an
active market for such contracts, no assurance can be given that a liquid market
will exist for any  particular  contract at any  particular  time.  Many futures
exchanges  and boards of trade  limit the  amount of  fluctuation  permitted  in
futures  contract  prices during a single  trading day. Once the daily limit has
been reached in a particular contract, no trades may be made that day at a price
beyond that limit or trading may be suspended for specified  periods  during the
trading  day.  Futures  contract  prices  could  move to the limit  for  several
consecutive  trading days with little or no trading,  thereby  preventing prompt
liquidation  of futures  positions and  potentially  subjecting the Portfolio to
substantial losses.

Successful  use of futures by the  Portfolio  also is subject to the  ability of
Wilshire to predict correctly  movements in the direction of the relevant market
and, to the extent the  transaction  is entered  into for hedging  purposes,  to
ascertain the appropriate  correlation  between the transaction being hedged and
the price movements of the futures contract.  For example, if the Portfolio uses
futures to hedge  against the  possibility  of a decline in the market  value of
securities  held in its  portfolio  and the  prices of such  securities  instead
increase,  the  Portfolio  will lose part or all of the benefit of the increased
value of securities  which it has hedged because it will have offsetting  losses
in its futures  positions.  Furthermore,  if in such circumstances the Portfolio
has  insufficient  cash, it may have to sell  securities to meet daily variation
margin  requirements.  The Portfolio may have to sell such  securities at a time
when it may be disadvantageous to do so.

Pursuant to regulations and/or published positions of the SEC, the Portfolio may
be  required  to  segregate  cash  or  liquid  assets  in  connection  with  its
commodities  transactions  in an  amount  generally  equal  to the  value of the
underlying  commodity.  The  segregation  of such assets will have the effect of
limiting the Portfolio's ability otherwise to invest those assets.

FUTURE  DEVELOPMENTS.  The Portfolio may take advantage of  opportunities in the
area of futures  contracts  and any other  Derivatives  which  presently are not
contemplated  for use by the Portfolio or which  currently are not available but
which may be developed,  to the extent such  opportunities  are both  consistent
with the  Portfolio's  investment  objective  and  legally  permissible  for the
Portfolio. Before entering into such transactions or making any such investment,
the Portfolio will provide appropriate disclosure in its Prospectus or SAI.

MANAGEMENT POLICIES

FUND INVESTMENT RESTRICTIONS.  The Portfolio has adopted investment restrictions
numbered 1 through 9 as fundamental  policies,  which cannot be changed  without
approval  by the  holders  of a  majority  (as  defined  in the 1940 Act) of the
Portfolio's  outstanding  voting  shares.  Investment  restrictions  numbered 10
through 12 are not fundamental policies and may be changed by vote of a majority
of the Directors at any time. The Portfolio may not:

1.  Invest in  commodities,  except that the  Portfolio  may  purchase  and sell
options and futures  contracts,  including those relating to indices and options
on futures contracts or indices.

2. Purchase,  hold or deal in real estate or oil, gas or other mineral leases or
exploration  or  development  programs,  but the Portfolio may purchase and sell
securities that are secured by real estate or issued by companies that invest or
deal in real estate.

3. Borrow money, except for temporary or emergency (not leveraging)  purposes in
an amount up to 33 1/3% of the value of the Portfolio's  total assets (including
the amount  borrowed)  based on the lesser of cost or market,  less  liabilities
(not  including the amount  borrowed) at the time the  borrowing is made.  While
borrowings exceed 5% of the value of the Portfolio's total assets, the Portfolio
will  not make any  additional  investments.  For  purposes  of this  investment
restriction,  the entry into options,  forward contracts,  or futures contracts,
including those relating to indices, and options on futures contracts or indices
shall not constitute borrowing.

4. Make loans to others, except through the purchase of debt obligations and the
entry into repurchase agreements.  However, the Portfolio may lend its portfolio
securities  in an amount not to exceed 33 1/3% of the value of its total assets.
Any  loans  of  portfolio  securities  will  be  made  according  to  guidelines
established by the SEC and the Company's Board of Directors.

5. Act as an underwriter  of securities of other  issuers,  except to the extent
the Portfolio may be deemed an underwriter  under the Securities Act of 1933, as
amended, by virtue of disposing of portfolio securities.

6. Invest more than 25% of its assets in the securities of issuers in any single
industry,  provided  there shall be no limitation on the purchase of obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities.

7. Invest more than 5% of its assets in the  obligations  of any single  issuer,
except  that up to 25% of the  value  of the  Portfolio's  total  assets  may be
invested,  and securities  issued or guaranteed by the U.S.  Government,  or its
agencies  or  instrumentalities  may be  purchased,  without  regard to any such
limitation.

8. Hold more than 10% of the outstanding voting securities of any single issuer.
This investment  restriction applies only with respect to 75% of the Portfolio's
total assets.

9. Issue any senior  security  (as such term is defined in Section  18(f) of the
1940 Act),  except to the extent that the  activities  permitted  in  investment
restrictions No. 1 and 3 may be deemed to give rise to a senior security.

10.  Invest  in the  securities  of a  company  for the  purpose  of  exercising
management or control, but the Portfolio will vote the securities it owns in its
portfolio as a shareholder in accordance with its views.

11. Enter into repurchase agreements providing for settlement in more than seven
days  after  notice  or  purchase  securities  which  are  illiquid,  if, in the
aggregate,  more than 15% of the value of the Portfolio's net assets would be so
invested.

12.  Purchase  securities of other  investment  companies,  except to the extent
permitted  under  the  1940  Act or  those  received  as  part  of a  merger  or
consolidation.

If a percentage  restriction  is adhered to at the time of  investment,  a later
change in  percentage  resulting  from a change  in  values  or assets  will not
constitute a violation of such restriction.

INVESTMENT ADVISORY AGREEMENT. Wilshire provides investment advisory services to
the  Portfolio   pursuant  to  Investment   Advisory  Agreement  (the  "Advisory
Agreement")  dated July 11,  1996 with the  Company  as  amended to include  the
Portfolio on June 8, 1998. As to the  Portfolio,  the Advisory  Agreement has an
initial term of two years and  thereafter  is subject to annual  approval by (i)
the  Company's  Board of Directors or (ii) vote of a majority (as defined in the
1940 Act) of the outstanding voting securities of such Portfolio,  provided that
in either event the continuance  also is approved by a majority of the Directors
who are not "interested  persons" (as defined in the 1940 Act) of the Company or
Wilshire,  by vote cast in person at a meeting  called for the purpose of voting
on such  approval.  As to the  Portfolio,  the Advisory  Agreement is terminable
without penalty,  on 60 days' notice,  by the Company's Board of Directors or by
vote of the holders of a majority  of the  Portfolio's  shares,  or, on not less
than 90 days'  notice,  by  Wilshire.  The  Advisory  Agreement  will  terminate
automatically,  as to the Portfolio,  in the event of its assignment (as defined
in the 1940 Act).

    The  following  persons  are  executive   officers  and directors of 
Wilshire: Dennis A. Tito, Chairman of the Board of Directors, President and

accordance with the stated  policies of the Portfolio,  subject to the oversight
of the  Company's  Board of  Directors.  Wilshire  provides the  Portfolio  with
portfolio  managers  who are  authorized  by the Board of  Directors  to execute
purchases and sales of securities.  The Portfolio's primary Portfolio Manager is
Thomas D. Stevens and he is assisted by David R. Borger.

ADMINISTRATION   AGREEMENT.   Pursuant  to  the  Administration  Agreement  (the
"Administration  Agreement")  with  the  Company,  Investor  Services  Group,  a
subsidiary  of  First  Data  Corporation,   4400  Computer  Drive,  Westborough,
Massachusetts  01581,  furnishes the Company clerical help and accounting,  data
processing,  internal  auditing and legal  services and certain  other  services
required by the Company, prepares reports to the Portfolio's  shareholders,  tax
returns, reports to and filings with the SEC and state Blue Sky authorities, and
generally  assists  in all  aspects  of the  Company's  operations,  other  than
providing investment advice.

The Agreement  continues in effect from year to year subject to annual  approval
by (i) the  Company's  Board of Directors or (ii) vote of a majority (as defined
in the 1940 Act) of the Portfolio's outstanding voting securities, provided that
in either event the continuance  also is approved by a majority of the Directors
who are not "interested  persons" (as defined in the 1940 Act) of the Company or
Investor  Services  Group,  by vote cast in person at a meeting  called  for the
purpose of voting on such approval.  The Administration  Agreement is terminable
without  penalty on 60 days' notice,  by the Company's  Board of Directors or by
vote of the holders of a majority  of the  Portfolio's  shares,  or, on not less
than 90 days' notice by Investor  Services Group. The  Administration  Agreement
will terminate  automatically  in the event of its assignment (as defined in the
1940 Act).

As compensation for Investor Services Group's services under the  Administration
Agreement,  Investor  Services  Group is entitled to receive  from the Company a
monthly  administration  fee at the  annual  rate of .15 of 1% of the  Company's
monthly average net assets up to aggregate assets of $1 billion,  .10 of 1% such
value  on the  next $4  billion,  and .08 of 1% on the  excess  net  assets.  In
addition, the Company has agreed to pay Investor Services Group an annual fee of
$25,000 for each series (including the Portfolio) and $2,000 for each additional
class.



<PAGE>


The Advisory  Agreement  provides that Wilshire shall exercise its best judgment
in rendering the services to be provided to the Portfolio  under the  Agreement.
Wilshire is not liable under the Advisory Agreement for any error of judgment or
mistake  of law or for any  loss  suffered  by the  Portfolio.  Wilshire  is not
protected,  however,  against any liability to the Portfolio or its shareholders
to which Wilshire would otherwise be subject by reasons of willful  misfeasance,
bad  faith or gross  negligence  in the  performance  of its  duties  under  the
Advisory  Agreement  or by  reason  of  Wilshire's  reckless  disregard  of  its
obligations and duties under the Advisory Agreement.

                                           SERVICE AND DISTRIBUTION PLAN

The Service and  Distribution  Plan of the Company  adopted  pursuant to Section
12(b)  of the  1940  Act  and  Rule  12b-1  thereunder  was  approved  as to the
Investment Class shares of the Portfolio by vote of the majority of both (a) the
Directors  of the  Company,  and (b) those  Directors of the Company who are not
interested  persons of the  Company,  and have no direct or  indirect  financial
interest in the operation of the Services Plan or any  agreements  related to it
(the "Independent  Directors"),  in each case cast in person at a meeting called
for the purpose of voting on the Service and Distribution Plan.

Under the  Service  and  Distribution  Plan,  FDDI is required to provide to the
Directors of the Company for their review, at least quarterly,  a written report
of the  amounts  expended  by the  Portfolio  and the  purposes  for which  such
expenditures were made.

The Service and  Distribution  Plan will  continue in effect with respect to the
Portfolio  only so long as such  continuance is  specifically  approved at least
annually by votes of the majority (or whatever other  percentage  may, from time
to time, be required by Section 12(b) of the  Investment  Company Act of 1940 or
the rules and regulations  thereunder) of both (a) the Directors of the Company,
and (b) the  Independent  Directors of the Company,  cast in person at a meeting
called for the  purpose of voting on the  Service  and  Distribution  Plan.  The
Service and  Distribution  Plan may not be amended in any material  respect with
respect to the  Portfolio  unless  such  amendment  is  approved by votes of the
majority (or whatever  other  percentage  may, from time to time, be required by
Section 12(b) of the Investment Company Act of 1940 or the rules and regulations
thereunder)  of both (a) the Directors of the Company,  and (b) the  Independent
Directors of the Company,  cast in person at a meeting called for the purpose of
voting on the Service and Distribution  Plan, and may not be amended to increase
materially the amount to be spent thereunder without such approvals and approval
by vote of at least a majority of the outstanding shares of the Investment Class
of the  Portfolio.  The Service and  Distribution  Plan may be terminated at any
time with  respect to the  Portfolio  by vote of a majority  of the  Independent
Directors  or, as to the  Portfolio,  by vote of a majority  of the  outstanding
shares of the Investment Class of the Portfolio.

                                           PURCHASE OF PORTFOLIO SHARES

The following information supplements and should be read in conjunction with the
section in the Prospectuses entitled "How to Buy Portfolio Shares."

THE DISTRIBUTOR.  FDDI, a subsidiary of Investor  Services Group,  4400 Computer
Drive,  Westborough,  Massachusetts  01581, serves as the Company's  distributor
pursuant to an agreement which is renewable  annually by the Board of Directors.
The Portfolio's shares are sold on a continuous basis by FDDI as agent, although
FDDI is not obligated to sell any particular amount of shares.  The Distribution
Agreement  between the  Distributor  and the Company  provides  that the Company
shall indemnify the Distributor  against any liability arising out of any untrue
statement of a material fact or any omission of a material fact in the Company's
registration  statement  necessary to make the  statements  therein  misleading,
unless such liability results from the Distributor's  willful  misfeasance,  bad
faith or negligence in the performance of its duties under the Agreement.

TRANSACTIONS  THROUGH SECURITIES DEALERS.  Portfolio shares may be purchased and
redeemed through  securities dealers which may charge a transaction fee for such
services.  Some  dealers  will place the  Portfolio's  shares in an account with
their firm.  Dealers  also may require  that the  customer  invest more than the
$1,000  minimum  investment,  the customer not take  physical  delivery of share
certificates,  the  customer not request  redemption  checks to be issued in the
customer's name, fractional shares not be purchased, or other conditions.

There is no sales or service charge to individual investors by the Company or by
FDDI,  although  investment  dealers,  banks  and  other  institutions  may make
reasonable  charges to investors for their services.  The services  provided and
the applicable fees are established by each dealer or other  institution  acting
independently  of the Company.  The Company  understands  that these fees may be
charged for customer services including, but not limited to, same-day investment
of client portfolios;  same-day access to client portfolios; advice to customers
about the status of their accounts,  yield currently being paid or income earned
to date;  provision of periodic  account  statements  showing security and money
market positions; and assistance with inquiries related to their investment. Any
such fees may be deducted  from the  investor's  account  monthly and on smaller
accounts  could  constitute a  substantial  portion of any  distribution  by the
Portfolio. Small, inactive, long-term accounts involving monthly service charges
may not be in the best  interest of  investors.  Investors  should be aware that
they may purchase shares of the Portfolio directly from the Company through FDDI
without  imposition  of any  maintenance  or service  charges,  other than those
already described herein. In some states, banks or other financial  institutions
effecting  transactions  in  Portfolio  shares may be  required  to  register as
dealers pursuant to state law.

IN-KIND PURCHASES. Payments for the Portfolio's shares may, at the discretion of
Wilshire,  be made in the form of securities  which are permissible  investments
for the Portfolio.  For further  information about this form of payment,  please
contact the  Transfer  Agent.  Generally,  securities  which are accepted by the
Portfolio  as  payment  for the  Portfolio's  shares  will be  valued  using the
Portfolio's  procedures  for valuing its own shares at the time the  Portfolio's
net asset value is next determined after receipt of a properly  completed order.
All  dividends,  interest,  subscription  or  other  rights  pertaining  to such
securities  will become the property of the  Portfolio  and must be delivered to
the Portfolio upon receipt from the issuer.  The Portfolio will require that (1)
it will have good and marketable title to the securities received by it; (2) the
securities  are in proper form for transfer to the Portfolio and are not subject
to any restriction on sale by the Portfolio under the Securities Act of 1933, as
amended,  or otherwise;  and (3) the Portfolio receives such other documentation
as Wilshire may, in its discretion, deem necessary or appropriate. Investors who
are subject to Federal  taxation  may realize a gain or loss for Federal  income
tax purpose upon such a payment.

                                          REDEMPTION OF PORTFOLIO SHARES

The following information supplements and should be read in conjunction with the
section in the Prospectuses entitled "How to Redeem Portfolio Shares."

WIRE  REDEMPTION  PRIVILEGE.  By using this Privilege,  the investor  authorizes
Investor  Services  Group (the  "Transfer  Agent")  to act on wire or  telephone
redemption  instructions from any person  representing  himself or herself to be
the  investor,  and  reasonably  believed by the  Transfer  Agent to be genuine.
Ordinarily,  the Company will initiate  payment for shares redeemed  pursuant to
this  Privilege  on the next  business day after  receipt if the Transfer  Agent
receives the  redemption  request in proper form.  Redemption  proceeds  ($1,000
minimum) will be transferred by Federal Reserve wire only to the commercial bank
account  specified by the  investor on the Account  Application  or  Shareholder
Services Form, or to a correspondent bank if the investor's bank is not a member
of the Federal  Reserve  System.  Fees  ordinarily  are imposed by such bank and
usually are borne by the investor.  Immediate  notification by the correspondent
bank to the investor's bank is necessary to avoid a delay in crediting the funds
to the investor's bank account.

To change the commercial  bank or account  designated to receive wire redemption
proceeds,  a written  request must be sent to the Transfer  Agent.  This request
must be signed by each shareholder,  with each signature guaranteed as described
below under "Stock Certificates; Signatures."

STOCK  CERTIFICATES;  SIGNATURES.  Any  certificates  representing  shares to be
redeemed  must be submitted  with the  redemption  request.  Written  redemption
requests must be signed by each  shareholder,  including  each holder of a joint
account,  and  each  signature  must  be  guaranteed.   Signatures  on  endorsed
certificates  submitted for  redemption  also must be  guaranteed.  The Transfer
Agent  has  adopted  standards  and  procedures   pursuant  to  which  signature
guarantees  in proper form  generally  will be  accepted  from  domestic  banks,
brokers,  dealers,  credit unions,  national  securities  exchanges,  registered
securities associations,  clearing agencies and savings associations, as well as
from participants in the New York Stock Exchange  Medallion  Signature  Program,
the  Securities  Transfer  Agents  Medallion  Program  ("STAMP")  and the  Stock
Exchanges  Medallion  Program.  Guarantees  must  be  signed  by  an  authorized
signatory  of the  guarantor  and  "Signature  Guaranteed"  must appear with the
signature.   The  Transfer  Agent  may  request  additional  documentation  from
corporations,  executors, administrators,  trustees or guardians, and may accept
other  suitable  verification  arrangements  from  foreign  investors,  such  as
consular   verification.   For  more   information  with  respect  to  signature
guarantees, please call the telephone number listed on the cover.

REDEMPTION  COMMITMENT.  The  Company  has  committed  itself to pay in cash all
redemption  requests by any shareholder of record,  limited in amount during any
90-day  period to the lesser of $250,000  or 1% of the value of the  Portfolio's
net assets at the  beginning  of such period.  Such  commitment  is  irrevocable
without the prior approval of the SEC. In the case of requests for redemption in
excess  of such  amount,  the  Board of  Directors  reserves  the  right to make
payments  in  whole  or in part in  securities  or  other  assets  in case of an
emergency  or any time a cash  distribution  would  impair the  liquidity of the
Portfolio  to the  detriment of the existing  shareholders.  In such event,  the
securities would be readily  marketable,  to the extent available,  and would be
valued in the same manner as the Portfolio's  investment  securities are valued.
If the recipient sold such securities, brokerage charges would be incurred.

SUSPENSION OF REDEMPTIONS.  The right of redemption may be suspended or the date
of payment  postponed (a) during any period when the New York Stock  Exchange is
closed (other than customary weekend and holiday closings),  (b) when trading in
the  markets  the  Portfolio  ordinarily  utilizes  is  restricted,  or  when an
emergency  exists as determined  by the SEC so that disposal of the  Portfolio's
investments  or   determination  of  its  net  asset  value  is  not  reasonably
practicable,  or (c) for such  other  periods  as the SEC by order may permit to
protect the Portfolio's shareholders.

NEW YORK STOCK EXCHANGE CLOSINGS.  The holidays (as observed) on which the New 
York Stock Exchange is closed currently are: New Year's Day, Presidents' Day,  
Rev. Martin Luther King, Jr. Day, Good Friday, Memorial Day, Independence Day, 
Labor Day, Thanksgiving and Christmas.

                                               SHAREHOLDER SERVICES

The following information supplements and should be read in conjunction with the
section in the Prospectus entitled "Shareholder Services."

EXCHANGES.  By using the Telephone Exchange  Privilege,  the investor authorizes
the  Transfer  Agent  to  act  on  telephonic   instructions   from  any  person
representing  himself or herself to be the investor and  reasonably  believed by
the  Transfer  Agent  to be  genuine.  Telephone  exchanges  may be  subject  to
limitations  as to the  amount  involved  or the number of  telephone  exchanges
permitted.  Shares  issued in  certificate  form are not eligible for  telephone
exchange.

To establish a personal retirement plan by exchange,  shares of the series being
exchanged must have a value of at least the minimum initial investment  required
for the series into which the  exchange is being made.  For Keogh  Plans,  IRAs,
Rollover IRA, Roth IRAs and IRAs set up under a Simplified Employee Pension Plan
("SEP-IRAs") with only one participant,  the minimum initial investment is $750.
To exchange  shares held in corporate  plans,  403(b)(7) Plans and SEP-IRAs with
more than one  participant,  the minimum initial  investment is $100 if the plan
has at least $1,000 invested among the series of the Company. To exchange shares
held in personal  retirement  plans,  the shares  exchanged  must have a current
value of at least $100.

The  exchange  service is available  to  shareholders  residence in any state in
which  shares of the series being  acquired  may legally be sold.  Shares may be
exchanged only between  accounts having  identical  names and other  identifying
designations.

The Company  reserves  the right to reject any  exchange  request in whole or in
part. The exchange service may be modified or terminated at any time upon notice
to shareholders.

CORPORATE  PENSION/PROFIT-SHARING  AND PERSONAL  RETIREMENT  PLANS.  The Company
makes   available  to   corporations   a  variety  of   prototype   pension  and
profit-sharing  plans.  In addition,  the Company makes  available  Keogh Plans,
IRAs,  including SEP-IRAs,  Roth IRAs and IRA "Rollover Accounts," and 403(b)(7)
Plans. Plan support services also are available. Investors can obtain details on
the various plans by calling the following toll-free number:
1-888-200-6796.



<PAGE>


Investors  who wish to purchase the  Portfolio's  shares in  conjunction  with a
Keogh Plan,  a 403(b)(7)  Plan or an IRA,  including an SEP-IRA or Roth IRA, may
request  from the Transfer  Agent forms for  adoption of such plans.  The entity
acting as custodian for Keogh Plans,  403(b)(7)  Plans or IRAs may charge a fee,
payment of which could require the  liquidation of shares.  All fees charged are
described in the  appropriate  form.  Shares may be purchased in connection with
these  plans  only by direct  remittance  to the  entity  acting  as  custodian.
Purchases for these plans will not be made in advance of receipt of Portfolios.

The minimum initial investment for corporate plans, 403(b)(7) Plans and SEP-IRAs
with  more  than  one  participant  is  $1,000  with no  minimum  on  subsequent
purchases.  The minimum initial investment for Keogh Plans,  IRAs,  SEP-IRAs and
403(b)(7) Plans with only one participant,  is normally $750, with no minimum on
subsequent  purchases.  Individuals  who open an IRA may also open a non-working
spousal IRA with a minimum investment of $250.

The investor should read the prototype  retirement plan and the appropriate form
of custodial agreement for further details on eligibility,  service fees and tax
implications, and should consult a tax adviser.

                                         DETERMINATION OF NET ASSET VALUE

The following information supplements and should be read in conjunction with the
section in the Prospectus entitled "How to Buy Portfolio Shares."

VALUATION OF PORTFOLIO  SECURITIES.  The Portfolio's  investment  securities are
valued at the last sale price on the securities  exchange or national securities
market on which such securities  primarily are traded.  Securities not listed on
an exchange or national  securities market, or securities in which there were no
transactions, are valued at the average of the most recent bid and asked prices.
Bid price is used when no asked price is available.  Short-term  investments are
carried at amortized cost,  which  approximates  value.  Any securities or other
assets for which recent market  quotations are not readily  available are valued
at fair value as determined  in good faith by the Board of  Directors.  Expenses
and fees,  including the advisory and administration fees, are accrued daily and
taken into  account  for the purpose of  determining  the net asset value of the
Portfolio's shares.

                                         DIVIDENDS, DISTRIBUTION AND TAXES

The following information supplements and should be read in conjunction with the
section in the Prospectus entitled "Dividends, Distributions and Taxes."

The Portfolio intends to qualify as a "regulated  investment  company" under the
Internal  Revenue Code of 1986,  as amended  (the  "Code").  Qualification  as a
regulated  investment  company  relieves the  Portfolio  from any  liability for
Federal  income taxes to the extent its earnings are  distributed  in accordance
with the  applicable  provisions  of the Code.  The term  "regulated  investment
company" does not imply the supervision of management or investment practices or
policies by any government agency.

Depending on the composition of the Portfolio's  income, all or a portion of the
dividends paid by the Portfolio  from net investment  income may qualify for the
dividends  received deduction  allowable to certain U.S. corporate  shareholders
("dividends received deduction").  In general,  dividend income of the Portfolio
distributed  to  qualifying  corporate  shareholders  will be  eligible  for the
dividends  received deduction only to the extent that (i) the Portfolio's income
consists of dividends  paid by U.S.  corporations  and (ii) the Portfolio  would
have been  entitled to the  dividends  received  deduction  with respect to such
dividend income if the Portfolio were not a regulated  investment  company.  The
dividends  received  deduction  for  qualifying  corporate  shareholders  may be
reduced  if the  shares  of the  Portfolio  held by them with  respect  to which
dividends  are received are treated as  debt-financed.  Pursuant to the Taxpayer
Relief Act of 1997, the dividends  received deduction is also not available to a
corporate  shareholder  if it held the shares of the Portfolio less than 46 days
during  the  90-day  period  that  begins  45  days  before  the  stock  becomes
ex-dividend  with respect to the dividend.  This holding  period  requirement is
applicable  to each  dividend  paid  by the  Portfolio.  In  addition  to  these
requirements, the Code provides other limitations with respect to the ability of
a qualifying corporate  shareholder to claim the dividends received deduction in
connection with holding the Portfolio's shares.

Any dividend or distribution paid shortly after an investor's  purchase may have
the effect of reducing the aggregate net asset value of shares below the cost of
investment.  Such a dividend or distribution  would be a return on investment in
an economic  sense. In addition,  the Code provides that if a shareholder  holds
shares of the  Portfolio  for six months or less and has  received  a  long-term
capital gain distribution with respect to such shares,  any loss incurred on the
sale of such shares will be treated as a long-term capital loss to the extent of
the long-term capital gain distribution received.

If a shareholder holds shares of the Portfolio while holding a short position in
a regulated  futures  contract or an option in such regulated  futures  contract
that  substantially  diminishes the shareholder's  risk of loss in its Portfolio
shares (an "offsetting  position"),  recently  proposed Internal Revenue Service
regulations  clarify that (i) any losses on the disposition of Portfolio  shares
will be required to be deferred to the extent of any unrealized  appreciation in
the short position and (ii) such holding will limit the shareholder's ability to
claim the  corporate  dividends  received  deduction  in  respect  of  Portfolio
dividends.

Ordinarily,  gains and  losses  realized  from  portfolio  transactions  will be
treated as a capital gain or loss.  All or a portion of the gain  realized  from
engaging in "conversion  transactions"  may be treated as ordinary  income under
Section 1258. "Conversion  transactions" are defined to include certain forward,
futures,  option and "straddle"  transactions,  transactions marketed or sold to
produce capital gains, or transactions  described in Treasury  regulations to be
issued in the future.

Under Section 1256 of the Code, a gain or loss  realized by the  Portfolio  from
certain financial futures  transactions will be treated as 60% long-term capital
gain or loss and 40%  short-term  capital gain or loss.  Gain or loss will arise
upon the exercise or lapse of such futures as well as from closing transactions.
In  addition,  any  such  futures  remaining  unexercised  at  the  end  of  the
Portfolio's  taxable  year will be treated  as sold for their  then fair  market
value,  resulting in additional gain or loss to the Portfolio  characterized  in
the manner described above.

Offsetting  positions  held by the  Portfolio  involving  financial  futures may
constitute  "straddles." Straddles are defined to include "offsetting positions"
in actively traded personal property. The tax treatment of straddles is governed
by  Sections  1092  and  1258 of the  Code,  which,  in  certain  circumstances,
overrides or modifies the  provisions of Section 1256. As such, all or a portion
of  any  short-  or  long-term  capital  gain  from  certain  "straddle"  and/or
conversion transactions may be recharacterized to ordinary income.

If the  Portfolio  were  treated as  entering  into  straddles  by reason of its
futures transactions, such straddles could be characterized as "mixed straddles"
if the futures  transactions  comprising such straddles were governed by Section
1256 of the Code.  The Portfolio may make one or more  elections with respect to
"mixed straddles." Depending upon which election is made, if any, the results to
the  Portfolio  may differ.  If no election is made,  to the extent the straddle
rules apply to positions  established by the Portfolio,  losses  realized by the
Portfolio  will be deferred to the extent of unrealized  gain in any  offsetting
positions.  Moreover, as a result of the straddle rules, short-term capital loss
on straddle  positions may be  recharacterized  as long-term  capital loss,  and
long-term  capital  gain  on  straddle   positions  may  be  recharacterized  as
short-term  capital gain, and as a result of the conversion  transaction  rules,
long-term capital gain may be recharacterized as ordinary income.

Under  Section 1259 of the Code,  enacted as part of the Taxpayer  Relief Act of
1997,  the Portfolio  will  recognize gain if it enters into a future or forward
contract  relating  to an  appreciated  direct  position  in any  stock  or debt
instrument,  or if it  acquires  stock or a debt  instrument  at a time when the
Portfolio  has  an  offsetting   appreciated  position  in  the  stock  or  debt
instrument. Such transactions are considered to be constructive sales for income
tax purposes.

Investment by the Portfolio in securities  issued or acquired at a discount,  or
providing  for  deferred  interest  or for  payment of  interest  in the form of
additional  obligations could under special tax rules affect the amount,  timing
and  character of  distributions  to  shareholders  by causing the  Portfolio to
recognize  income  prior to the  receipt  of cash  payments.  For  example,  the
Portfolio  could be  required  to accrue a portion  of the  discount  (or deemed
discount) at which the securities  were issued each year and to distribute  such
income in order to maintain its qualification as a regulated investment company.
In such case,  the Portfolio  may have to dispose of  securities  which it might
otherwise  have  continued  to hold in order to generate  cash to satisfy  these
distribution requirements.

                                              PERFORMANCE INFORMATION

The following information supplements and should be read in conjunction with the
section in the Prospectus entitled "Performance Information."

From time to time, quotations of the Portfolio's performance may be presented in
advertisements,  sales  literature  or reports to  shareholders  or  prospective
investors.  All performance information is calculated separately for each class.
The data is calculated as follows:

Average annual total return is calculated by determining  the ending  redeemable
value  of  an  investment  purchased  at  net  asset  value  per  share  with  a
hypothetical  $1,000  payment made at the beginning of the period  (assuming the
reinvestment  of  dividends  and  distributions),  dividing by the amount of the
initial  investment,  taking  the "nth" root of the  quotient  (where "n" is the
number of years in the period) and subtracting 1 from the result.

Total return is calculated by subtracting  the amount of the net asset value per
share at the  beginning of a stated period from the net asset value per share at
the end of the period (after giving effect to the  reinvestment of dividends and
distributions during the period), and dividing the result by the net asset value
per share at the beginning of the period.

From  time to  time,  advertising  materials  for the  Portfolio  may  refer  to
Morningstar ratings and related analysis supporting such ratings.

                                              PORTFOLIO TRANSACTIONS

Wilshire  supervises  the placement of orders on behalf of the Portfolio for the
purchase or sale of portfolio securities.  Allocation of brokerage transactions,
including  their  frequency,  is made in the best  judgment of Wilshire and in a
manner deemed fair and reasonable to shareholders.  The primary consideration is
prompt  execution  of orders at the most  favorable  net price.  Subject to this
consideration, the brokers selected may include those that supplement Wilshire's
research  facilities with statistical  data,  investment  information,  economic
facts and opinions. Information so received is in addition to and not in lieu of
services  required to be performed by Wilshire and its fees are not reduced as a
consequence of the receipt of such  supplemental  information.  Such information
may be useful to Wilshire in serving both the  Portfolio and other clients which
it advises and, conversely,  supplemental  information obtained by the placement
of  business of other  clients  may be useful to  Wilshire  in carrying  out its
obligations to the Portfolio. Brokers also are selected because of their ability
to handle special executions such as are involved in large block trades or broad
distributions, provided the primary consideration is met. Large block trades, in
certain cases,  may result from two or more clients  Wilshire might advise being
engaged  simultaneously  in the  purchase  or sale of the  same  security.  When
transactions  are executed in the  over-the-counter  market,  the Portfolio will
deal with the primary market makers unless a more  favorable  price or execution
otherwise is obtainable.

Portfolio  turnover may vary from year to year, as well as within a year.  Under
normal market  conditions,  the  Portfolio's  turnover rate  generally  will not
exceed 10%. High turnover  rates are likely to result in  comparatively  greater
brokerage expenses.  The overall reasonableness of brokerage commissions paid is
evaluated by Wilshire  based upon its knowledge of available  information  as to
the general  level of  commissions  paid by other  institutional  investors  for
comparable services.

                                          INFORMATION ABOUT THE PORTFOLIO

The following information supplements and should be read in conjunction with the
section in the Prospectus entitled "General Information."

Each  share of the  Portfolio  has one vote  and,  when  issued  and paid for in
accordance  with the terms of the  offering,  is fully paid and  non-assessable.
Shares of each class of the  Portfolio  have equal rights as to dividends and in
liquidation.  Shares have no preemptive,  subscription or conversion  rights and
are freely transferable.

Rule 18f-2 under the 1940 Act provides that any matter  required to be submitted
under the provisions of the 1940 Act or applicable state law or otherwise to the
holders of the outstanding voting securities of an investment  company,  such as
the  Company,  will not be deemed to have been  effectively  acted  upon  unless
approved by the holders of a majority  of the  outstanding  shares of the series
affected by such  matter.  Rule 18f-2  further  provides  that a series shall be
deemed to be affected by a matter  unless it is clear that the  interests of all
series in the  matter  are  identical  or that the  matter  does not  affect any
interest of all series.  However,  the Rule exempts the selection of independent
accountants and the election of Directors from the separate voting  requirements
of the Rule.  Rule  18f-3  under the 1940 Act makes  further  provision  for the
voting rights of each class of shares,  such as the Investment Class shares,  of
an  investment  company  which issues more than one class of voting  shares.  In
particular,  Rule 18f-3  provides  that each class shall have  exclusive  voting
rights on any matter submitted to shareholders that relates solely to the class'
arrangement for services and expenses,  and shall have separate voting rights on
any matter  submitted to shareholders in which the interests of one class differ
from the interests of any other class.

The Company will send annual and  semi-annual  financial  statements  to all its
shareholders.
