THE WRIGHT ASSET ALLOCATION TRUST:
OVERVIEW OF PRINCIPAL STRATEGIES
- -------------------------------------------------------------------------------


The Wright  Asset  Allocation  Trust was  created to offer a variety of funds to
meet differing investment  objectives.  Each fund is a fund of funds. This means
that a fund invests in other mutual funds managed by Wright  Investors  Service.
Only Wright Managed Growth with Income Fund is currently  offered.  Depending on
Wrights model asset  allocation for the fund, the fund may invest in some or all
of the following Wright Blue Chip Funds.


- ----- Side Bar Text -----
                                    Blue Chip

Financial  dictionaries define Blue Chip as a common stock of a company that has
a long record of profit growth and dividend payment and a reputation for quality
management,  products and services.  Wright further refines this to include only
securities issued by companies that meet its qualitative standards.

- -----End Side Bar Text-----

   o WRIGHT SELECTED BLUE CHIP EQUITIES  PORTFOLIO  (WSBC) seeks long-term total
     return  by  investing  in equity  securities  of  well-established  quality
     companies  whose  current  operations  reflect  characteristics  likely  to
     provide comparatively superior total investment return.

   o WRIGHT JUNIOR BLUE CHIP EQUITIES  PORTFOLIO  (WJBC) seeks  long-term  total
     return by  investing  in equity  securities  of smaller  companies.  Wright
     selects  companies  that have  strong  balance  sheets  and  strong  recent
     earnings and price momentum.  Selected companies generally have both growth
     and  value  characteristics  and  some  companies  may  not  currently  pay
     dividends on their shares.

   o WRIGHT MAJOR BLUE CHIP EQUITIES FUND (WMBC) seeks total return by investing
     in the equity securities of larger companies. The market capitalizations of
     these companies are similar to that of the Standard and Poor's 500 Index.

   o WRIGHT INTERNATIONAL BLUE CHIP EQUITIES PORTFOLIo (WIBC) seeks total return
     by investing in equity securities of well-established  non-U.S.  companies.
     Wright focuses on individual  stock selection  instead of trying to predict
     which  country or industry  will perform  best.  No more than 20% of assets
     will be invested in any one country.

   o WRIGHT U.S.  GOVERNMENT NEAR TERM PORTFOLIO  (WNTB) seeks a higher level of
     income than is normally above that available from  short-term  money market
     instruments  by investing in U.S.  Government  obligations of all types and
     maintaining an average weighted maturity of less than five years.

   o WRIGHT U.S.  TREASURY  PORTFOLIO  (WUSTB)  seeks a high total return with a
     high level of income by investing in U.S. Treasury bills, notes and bonds.

   o WRIGHT TOTAL RETURN BOND FUND (WTRB) seeks a superior  rate of total return
     by  investing  in U.S.  Government  and high grade  (rated  "AA" or higher)
     corporate debt  securities of companies  meeting Wright quality  standards.
     Wright  allocates  assets among  different  market  sectors with  different
     maturities  based  on its view of the  relative  value  of each  sector  or
     maturity.

   o WRIGHT CURRENT INCOME PORTFOLIO (WCIF) seeks a high level of current income
     with moderate  fluctuations  of principal by investing in debt  obligations
     issued or  guaranteed by the US.  Government  or any of its  agencies,  and
     corporate debt  securities.  Since  inception,  this portfolio has invested
     almost exclusively in mortgage-backed securities of the Government National
     Mortgage Association.

You should understand that, when investing in a fund of funds, you will bear the
operating  expenses of the  underlying  funds as well as your share of the funds
operating expenses.  For example,  you will pay a management or asset allocation
fee for the fund and management fees for the underlying fund.

reduced risk. This objective may be changed without shareholder approval.



(Graphic - Compass)
PRINCIPAL INVESTMENT STRATEGIES
The fund is a balanced fund  investing its assets in various Wright managed
equity  and  income  funds.  Wright  allocates  the  fund's  assets  based  on a
fundamental  analysis  of the  economy and  investment  markets in the U.S.  and
foreign countries.  Over the long-term, the fund expects to have an asset mix of
65 percent  equity (10 percent is  international  equity)  and 35 percent  fixed
income.  This mix will vary over short-term  periods as Wright follows a dynamic
process  of  monitoring  the  asset  allocation  model and  making  adjustments.
Purchases  and  sales of funds  are made  when  necessary  to  adjust  the asset
allocation  model,  when new investments  become  available to the fund, or when
necessary to accomodate  redemption  activity.  The equity  allocation may range
from 0 to 75 percent with up to 20 percent  being  international  equities.  The
U.S.  equities may be allocated  among large,  medium and small  companies.  The
fixed income  allocation  may range from 25 to 100  percent.  Fixed income funds
selected could include those investing in U.S.  government issues,  high quality
corporate  issues and mortgage  backed  securities  issued and  guaranteed as to
timely  payment of principal and interest by the  Government  National  Mortgage
Association.  Up to 50 percent of the fixed income  allocation could be in money
market securities.


At the end of 1998 the asset  allocation model for growth with income called for
a mix of 55%  equities  and 45% fixed  income.  This was  further  allocated  as
follows:

   o Wright Major Blue Chip Equities Fund               12%
   o Wright Selected Blue Chip Equities Portfolio       25%
   o Wright Junior Blue Chip Equities Portfolio          3%
   o Wright International Blue Chip Equities Portfolio  15%
   o Wright Total Return Bond Fund                      35%

The remaining 10% of the fund's assets were invested in U.S. Treasury bills and
similar money market securities.

(Graphic - Life Preserver)
PRINCIPAL RISKS
In addition to normal market and management risks, the fund may invest in equity
funds that have specific risks. These risks are:

     o  WRIGHT MAJOR BLUE CHIP EQUITIES FUND.  Performance could be adversely
        affected if large capitalization or value stocks fall out of favor an
        returns trail the overall stock market.
     o  WRIGHT  SELECTED  BLUE CHIP  EQUITIES  PORTFOLIO.  Performance  could be
        adversely affected if mid-cap or value stocks fall out of favor with the
        market and returns trail the overall market. Also, if selected companies
        remain undervalued or experience an adverse event such as an unfavorable
        earnings report.
     o  WRIGHT  JUNIOR  BLUE  CHIP  EQUITIES  PORTFOLIO.  Performance  could  be
        adversely  affected if small company  securities  fall out of favor with
        the market and  returns  trail the  overall  market.  The price of small
        company securities may reflect greater risk due to narrow product lines,
        limited  financial  resources,  less  depth in  management  or a limited
        trading market.
     o  WRIGHT  INTERNATIONAL BLUE CHIP EQUITIES PORTFOLIO.  Foreign investments
        are subject to special risks including currency risk (changes in foreign
        currency  rates  reducing  the  value of the  fund's  assets),  seizure,
        expropriation  or   nationalization   of  a  company,   lack  of  public
        information, and the impact of political, social, or diplomatic events.

- -----Side Bar Text-----
                                A Word About Risk

Before you invest in any mutual fund, you should  understand the risks involved.
There are two basic risks  prevalent in mutual funds investing in common stocks,
such as the fund. They are:

o MARKET RISK: when the prices of stocks fall, the value of the fund's
  investments may fall and you could lose money on your investment.

o MANAGEMENT RISK: Wright's strategy may not produce the expected results,
  causing losses.

- -----End Side Bar Text-----

In addition, fixed income funds may be subject to special risks such as:

     o  CREDIT OR DEFAULT RISK:  An issuer's  credit rating may be downgraded as
        the issuer may be unable to pay principal and interest obligations.
     o  INTEREST RATE RISK:  Bond prices fall when interest  rates rise and vice
        versa.  The longer the maturity of the bonds,  the greater the change in
        price.

<PAGE>

     o  PREPAYMENT   RISK:  When  interest  rates  decline,   the  issuer  of a
        mortgage-backed  or other debt security may exercise an option to prepay
        the principal. This forces reinvestment in lower yielding securities.
     o  EXTENSION RISK: When interest rates rise, the life of a  mortgage-backed
        security is extended beyond the expected  prepayment time,  reducing the
        value of the security.

Also, the fund's income may decline during times of falling interest rates.

When the market is  unfavorable,  the fund's assets may be held  temporarily  in
cash or invested in  short-term  obligations  without  limit.  Although the fund
would do this to  reduce  losses,  defensive  investments  may  hurt the  fund's
efforts to achieve  its  investment  objective.  Likewise,  Wright's  efforts to
maximize returns while minimizing risk may not be successful.

(Graphic - Assorted Nautical Flags)
WHO MAY WANT TO INVEST
You may be  interested  in the  fund  if you are  seeking  an  actively  managed
well-diversified  balanced  investment  portfolio  with the fund's  objective of
growth with a high level of income.  The fund will be of particular  interest to
individuals wishing to have a professional  investment adviser make the decision
when to enter or exit different markets.

Advisor Shares have been created for use in 401(k) and similar retirement plans.
Individual  Shares were created for  individuals  who wish to invest directly or
through  their bank or other  financial  institution.  The fund is intended  for
those seeking a long-term investment commitment.

(Graphic - Ship's Log)
PAST PERFORMANCE
The fund has no prior operating history and no past performance  record.  Wright
manages  certain  private  balanced  investment  accounts which have  investment
objectives  and  strategies  that are  identical to the fund's and invest in the
same Blue Chip Funds.  The  performance  of these  accounts  for the years ended
December 31, 1998 is on page 8.

- -----Side Bar Text-----
                             Understanding Expenses

Annual fund  operating  expenses are paid by the fund. As a result,  you pay for
them  indirectly  because they reduce the fund's return.  Fund expenses  include
management  fees,  12b-1  fees and  administrative  costs,  such as  shareholder
recordkeeping  and reports,  custodian and pricing  services,  and  registration
fees.

- -----End Side Bar Text-----

Example
The following example allows you to compare the cost of investing in the fund to
the cost of  investing  in other  mutual funds by showing what your costs may be
over  time.  It  uses  the  same  assumptions  that  other  funds  use in  their
prospectuses:  $10,000 initial  investment,  5% total return for each year, fund
operating  expenses remain the same for each period and redemption after the end
of each period.  Your actual  costs may be higher or lower,  so use this example
for comparison  only.  Based on these  assumptions your costs at the end of each
period would be:
                                                         1 Year       3 Years
- -------------------------------------------------------------------------------
            Individual Shares with redemption              $303         $627
            Individual Shares without redemption           $203         $627
            Advisor Shares                                 $153         $474
<PAGE>

INFORMATION ABOUT YOUR ACCOUNT
- -------------------------------------------------------------------------------

HOW THE FUND VALUES ITS SHARES
The price at which you buy,  sell or exchange fund shares is the net asset value
per share or NAV. The NAV is calculated  at the close of regular  trading on the
New York Stock Exchange (normally 4:00 p.m. New York time) each day the Exchange
is open. It is not  calculated on days the Exchange is closed.  The value of the
fund's assets may change on days when the Exchange is not open.  You will not be
able to purchase,  redeem or exchange the fund's shares on those days. The price
for a purchase, redemption or exchange of fund shares is the next NAV calculated
after your request is received.

When the fund calculates its NAV, it values the underlying  funds at their asset
values. Other portfolio securities are valued at the last current sales price on
the market where the  security is normally  traded.  Securities  that can not be
valued at these closing  prices are valued by Wright at fair value in accordance
with procedures adopted by the trustees. This could happen if an event after the
close  of the  market  seemed  likely  to have a major  impact  on the  price of
securities traded on the market. Although the fund calculates its value each day
the  Exchange  is open,  the NAV  reported  to NASDAQ for  distribution  to news
agencies will be delayed by one day.

- -----Side Bar Text-----
                                 Determining NAV

Share price is determined by adding the value of a fund's investments, cash and
other assets attributable to the class, deducting liabilities, and then dividing
that amount by the total number of shares outstanding for that class.

- -----End Side Bar Text-----

PURCHASING SHARES

Purchasing Shares for Cash
Shares of the fund are sold without an up-front sales charge at NAV. The minimum
initial  investment is $1,000 for either  Advisor  Shares or Individual  Shares.
There are no minimums for subsequent investments.

Waiver of the  Minimum  Initial  Investment:  The  minimums  may be  waived  for
investments  by  bank  trust  departments,   401(k)  or  similar   tax-sheltered
retirement plans and automatic investment program accounts.  The minimum initial
investment  will be  reduced  to  $500  for  shares  purchased  through  certain
investment  advisers,  financial planners,  brokers or other intermediaries that
charge a fee for their  services.  The fund has the right to reject any purchase
order, or limit or suspend the offering of its shares.

Authorized dealers,  including investment dealers,  banks or other institutions,
may impose  investment  minimums higher than those imposed by the fund. They may
also charge for their services. There are no charges if you purchase your shares
directly from the fund.

Buying Fund Shares
     o  If you are buying shares  directly  from the fund,  please refer to your
        Shareholder Manual for instructions on how to buy fund shares.
     o  If you buy shares  through  bank trust  departments  or other  fiduciary
        institutions, please consult your trust or investment officer.
     o  If you buy  shares  through a broker,  please  consult  your  broker for
        purchase instructions.
     o  If you buy  shares  through  an  account  with a  registered  investment
        adviser or financial planner,  please contact your investment adviser or
        planner.
     o  If you buy shares of the fund through a retirement plan,  please consult
        your plan documents or speak with your plan administrator.

- -----Side Bar Text-----
                                Paying for Shares

You  may pay for  shares  by  wire,  check,  Federal  Reserve  draft, or  other
negotiable  bank draft,  payable in U.S.  dollars and drawn on U.S banks. Third
party checks will not be accepted. A charge is imposed on any returned checks.

- -----End Side Bar Text-----
<PAGE>

DISTRIBUTION AND SERVICE PLANS

The fund has adopted a 12b-1 plan  permitting it to pay a fee in connection with
the distribution of its shares.  Wright Investors'  Service  Distributors,  Inc.
(WISDI),  the  principal  underwriter  and  distributor  of the  fund's  shares,
receives a  distribution  fee of up to 0.75% of the average  daily net assets of
the  Individual  Share class and up to 0.25% of the average  daily net assets of
the Advisor Share class.  Because this fee is paid on an ongoing basis, this may
cost you more than other types of sales charges over time.

The  fund has  also  adopted  a  service  plan.  This  plan  allows  WISDI to be
reimbursed for payments to intermediaries  for providing account  administration
and personal and account maintenance  services to fund shareholders.  The annual
service fee may not exceed  0.25% of the average  daily net assets of each class
of shares.

- -----Side Bar Text-----
                              Signature Guarantees

Signature  guarantees  are  used  to  protect  you and the  fund  from  possible
fraudulent  requests for redeemed  shares.  They are required on all requests to
change  account  application  information  and for certain  redemption  requests
including  any that  direct that  redemption  proceeds be sent to other than the
address of record. See the Shareholders Manual for more information.

- -----End Side Bar Text-----

SELLING SHARES
You may redeem or sell shares of the fund on any  business  day.  NO  REDEMPTION
REQUEST WILL BE PAID UNTIL YOUR SHARES HAVE BEEN PAID FOR IN FULL. IF THE SHARES
TO BE REDEEMED  REPRESENT AN INVESTMENT  MADE BY CHECK,  THE REDEMPTION  PAYMENT
WILL BE  DELAYED  UNTIL  THE  CHECK HAS BEEN  COLLECTED,  WHICH  MAKE TAKE UP TO
FIFTEEN  DAYS  FROM THE DATE OF  PURCHASE.  Telephone  and  internet  redemption
procedures  are  described  in the  Shareholder  Manual.  Individual  Shares are
subject to a 1%  contingent  deferred  sales  charge if sold  within one year of
purchase.

Redemption  requests  received in "proper  form"  before 4:00 p.m. New York time
will be  processed  at that day's  NAV.  "Proper  form"  means that the fund has
received your  request,  all shares are paid for, and all  documentation,  along
with any required  signature  guarantees,  are included.  The fund normally pays
redemption proceeds by check on the next business day to the address of record.
Payment  will  be  by  wire  if  you  specified  this  option  on  your  account
application.

- -----Side Bar Text-----
                               Redemption Proviso
In times of  drastic  economic  or market  conditions,  you may have  difficulty
selling shares by telephone or the internet,  so you should send your request by
mail  or  overnight  delivery.  These  redemption  options  may be  modified  or
terminated without notice to shareholders.

- -----End Side Bar Text-----

Individual  shares  redeemed  within 12  months of  purchase  are  subject  to a
contingent deferred sales charge of one percent of purchase price.

For more information about selling your shares, please refer to your Shareholder
Manual or consult your trust officer, adviser or plan administrator.

Involuntary Redemption
If your account falls below $500 the fund may redeem your shares.  You will
receive notice 60 days before this happens. Your account will not be redeemed if
the balance is below the minimum due to investment losses.

EXCHANGING SHARES
Individual  Shares may be exchanged  for  Individual  Shares of Catholic  Values
Investment  Trust Equity  Fund.  Advisor  Shares may be  exchanged  for Standard
Shares of the Wright Managed Blue Chip  Investment  Funds.  See the  Shareholder
Manual for detailed instructions.

You are limited to four "round-trip"  exchanges each year. A round-trip exchange
is an  exchange of one fund into  another  Wright  fund,  and then back into the
original fund. You will receive notice 60 days before the fund materially amends
or terminates the exchange privilege.

- -----Side Bar Text-----
                                  Market-Timers

The fund  believes  that use of the exchange  privilege  by investors  utilizing
market-timing  strategies adversely affects other fund shareholders.  Therefore,
the fund  generally will not honor  requests for exchanges by  shareholders  who
identify  themselves or are  identified as  "market-timers."  Market-timers  are
identified as those  investors who  repeatedly  (more than once) make  exchanges
within a short period.  The fund does not  automatically  redeem shares that are
the subject of a rejected exchange request.

<PAGE>


DIVIDENDS AND TAXES
- ------------------------------------------------------------------------------

DIVIDENDS AND DISTRIBUTIONS

Unless you tell us that you want to receive your distributions in cash, they are
reinvested  automatically in fund shares. The fund generally makes two different
kinds of distributions:

     o Capital gains from the sale of investments or other  transactions.  The
       fund will distribute any net realized capital gains annually,  normally
       in December. Capital gains are the main source of distributions paid by
       the fund.

     o Net investment income from interest or dividends. The fund generally will
       distribute its net investment income quarterly.

TAX CONSEQUENCES
Selling,  redeeming,  or exchanging mutual fund shares may result in a gain or a
loss  and is a  taxable  event.  Distributions,  whether  received  in  cash  or
reinvested in additional shares of the fund, are subject to federal income tax.

         Transaction                                      Tax Status

         Income dividends                               Ordinary income
         Short-term capital gains distribution          Ordinary income
         Long-term capital gains distribution           Long-term capital gains

The  international  fund may be subject to  foreign  withholding  taxes or other
foreign taxes on some of its foreign investments.  This will reduce the yield or
total  return on those  investments  and may affect the return of the fund if it
invests in the international fund.

Your  investment  in the fund could have  additional  tax  consequences.  Please
consult your tax advisor on federal, state, local or other applicable tax laws.

- -----Side Bar Text-----
                               Tax Considerations

  Unless your investment is in a tax-deferred account you may want to avoid:
 o Investing  in the fund near the end of its fiscal  year; if the fund makes a
   distribution of net investment income or capital gains you will receive some
   of your investment back as a taxable distribution.
 o Selling  shares at a loss for tax  purposes and making an investment  in the
   fund within 30 days before or after the sale. This  results in a "wash sale"
   and you will not be allowed to claim a tax loss.

MANAGING THE FUNDS
- -------------------------------------------------------------------------------


WRIGHT INVESTORS SERVICE, THE INVESTMENT ADVISER

Wright Investors' Service, Inc. manages the fund and its investments.  Wright is
located at 1000 Lafayette  Boulevard,  Bridgeport,  CT 06604.  Wright receives a
monthly  advisory  fee for its  services in the amount of 0.20%  annually of the
fund's  average  annual net  assets.  It also  receives  advisory  fees from the
underlying funds.

Wright is a leading independent international investment management and advisory
firm with more than 35 years  experience.  Wright  manages about $4.5 billion of
assets  in  portfolios  of all  sizes  and  styles as well as a family of mutual
funds.  The Wright Asset Allocation Trust may invest in as many as nine of these
funds.

Wright  developed  Worldscope(R),  one of the world's  largest and most complete
databases of financial  information,  which currently  includes more than 19,000
companies  in  49  nations.  Using  a  bottom-up  fundamental  approach,  Wright
systematically  identifies  those companies in the  Worldscope(R)  database that
meet minimum  standards of prudence and thus are suitable for  consideration  by
fiduciary  investors.  These companies are then subjected to extensive  analysis
and  evaluation  to identify  those that meet  Wright's  standards of investment
quality.  These standards focus on liquidity,  financial strength,  stability of
profits and growth.

                             Fundamental Analysis

The analysis of company financial  statements to forecast future price movements
using past records of assets, earnings, sales, products, management and markets.
It differs from technical analysis which relies on price and volume movements of
stocks and does not concern itself with financial statistics.

                      "Bottom-Up" Approach to Investing

The analysis of company  information  before  considering the impact of industry
and economic trends.  It differs from the "top-down"  approach which looks first
at the economy, then the industry and last the company.

Only those  companies  meeting or  exceeding  these  standards  are eligible for
selection by the Wright investment committee for inclusion on an Approved Wright
Investment List (AWIL).  There are separate AWILs for U.S.  companies,  non-U.S.
companies, small companies and fixed income securities.  Different standards may
apply to each list.  For  example,  smaller  companies  may have a lower  market
capital  requirement but a higher standard of profitability and growth.  All the
companies on the lists are  considered  by Wright to be "Blue Chips." This means
that the companies have established records of earnings profitability and equity
growth. All have established investment acceptance and active, liquid markets.


Investment Committee
An investment  committee of senior officers controls the investment  selections,
policies and  procedures of the fund.  These officers are  experienced  analysts
with different areas of expertise,  and have over 195 years of combined  service
with Wright.  The committee makes all decisions for the asset  allocation  model
for the fund of funds and for the selection, purchase and sale of all securities
for the Blue Chip Funds.  The  investment  committee  consists of the  following
members:

The  performance  of these accounts is not that of the fund, is not a substitute
for the fund's performance and does not predict the fund's performance  results,
which may differ from the private  accounts'  results.  Performance  data in the
chart are net of the  expenses of the Wright  managed  mutual funds in which the
accounts invest and of the management fee paid by the accounts.


The management fees and expenses of the private  accounts in some instances
could be higher than the estimated fees/expenses of the fund, which could result
in lower  performance.  Private  accounts are not subject to certain  investment
limitations,  diversification requirements and other restrictions imposed by the
Investment  Company Act of 1940 and the Internal  Revenue Code.  If  applicable,
these  limitations  and  restrictions  could  lower the  performance  results of
private  accounts.  However,  Wright  believes  that all of  these  limitations,
diversification  requirements and other  restrictions  were met by the accounts.
Performance has been calculated  using the Association of Investment  Management
and Research (AIMR) performance method, which may differ from the SEC method.


Master/Feeder Fund Structure
Six of the Blue  Chip  Funds in which  the fund  may  invest  are  organized  as
"master" funds. These include:

     o  Wright Selected Blue Chip Equities Portfolio
     o  Wright Junior Blue Chip Equities Portfolio
     o  Wright International Blue Chip Equities Portfolio
     o  Wright U.S. Treasury Portfolio
     o  Wright U.S. Government Near Term Portfolio
     o  Wright Current Income Portfolio
<PAGE>

These  portfolios  are organized as trusts and are treated as  partnerships  for
federal tax purposes.  Partnerships are "pass-through-entities" which means that
they do not pay federal taxes;  instead,  all of their realized gains or losses,
other  income,  and  expenses are  allocated  to, and taken into account for tax
purposes by, the fund and the other investors in the portfolios.


YEAR 2000 READINESS
Mutual  funds and  businesses  around the world could be  adversely  affected if
computers do not properly process  date-related  information with respect to the
Year 2000. Wright is addressing this issue and is getting reasonable  assurances
from the fund's other major service providers that they too are addressing these
issues  to  preserve  smooth   functioning  of  the  fund's  trading,   pricing,
shareholder account, custodial and other operations.  Wright is also considering
the  vulnerability  to Year 2000  problems  of  companies  in which the funds or
portfolios invest.

Improperly  functioning  computers may disrupt  securities  markets or result in
overall  economic  uncertainty.  Individual  companies  may  also  be  adversely
affected by the cost of fixing  their  computers,  which  could be  substantial.
There is no guarantee that all problems will be avoided.

                                  Administrator

Eaton Vance Management serves as the fund's administrator and is responsible for
managing its daily business  affairs.  Eaton Vance's services include  operating
the fund's order room, recordkeeping, preparing and filing documents required to
comply with federal and state  securities  laws,  supervising  activities of the
fund's custodian and transfer agent, providing assistance in connection with the
trustees' and shareholders' meetings and other administrative services.

The Euro
The European countries have adopted the Euro as their common currency.  Existing
national  currencies of these countries will be sub-currencies of the Euro until
July 1, 2002, when the old currencies will disappear entirely.  The introduction
of the Euro presents some possible risks, which could adversely affect the value
of securities  held by the fund, as well as possible  adverse tax  consequences.
There  could be  unpredictable  effects  on trade  and  commerce,  resulting  in
increased volatility for all financial markets.

THE WRIGHT ASSET ALLOCATION TRUST

     The  Wright  Asset  Allocation  Trust  is an  open-end  management  company
registered under the Investment  Company Act of 1940. The Trust was organized as
a Massachusetts  trust on June 17, 1997. The fund is a diversified series of the
Trust.

     The Trust's  Declaration of Trust may be amended with the affirmative  vote
of a majority of the  outstanding  shares of the Trust or, if only the interests
of the fund are  affected,  a majority  of the fund's  outstanding  shares.  The
trustees are authorized to make  amendments to the  Declaration of Trust without
shareholder approval that do not have a material adverse effect on the interests
of  shareholders.  The Trust may be terminated  (i) upon the sale of the Trust's
assets to another investment  company,  if approved by the holders of two-thirds
of the outstanding  shares of the Trust,  except that if the Trustees  recommend
such sale of  assets,  the  approval  by the vote of a majority  of the  Trust's
outstanding shares will be sufficient, or (ii) upon liquidation and distribution
of the assets of the Trust,  if approved by a majority of its Trustees or by the
vote of a majority of the Trust's outstanding shares. If not so terminated,  the
Trust may continue indefinitely.

     The Trust's  Declaration  of Trust further  provides that the Trustees will
not be liable  for  errors of  judgment  or  mistakes  of fact or law;  however,
nothing in the  Declaration of Trust protects a Trustee against any liability to
which he would otherwise be subject by reason of willful misfeasance, bad faith,
gross negligence, or reckless disregard of the duties involved in the conduct of
his office.

     The Trust is an organization of the type commonly known as a "Massachusetts
business  trust." Under  Massachusetts  law,  shareholders  of such a trust may,
under  certain  circumstances,  be held  personally  liable as partners  for the
obligations of the trust.  The Trust's  Declaration of Trust contains an express
disclaimer of shareholder liability in connection with the Trust property or the
acts,  obligations  or  affairs  of the  Trust.  The  Declaration  of Trust also
provides for  indemnification  out of the Trust property of any shareholder held
personally  liable for the claims and  liabilities  to which a  shareholder  may
become subject by reason of being or having been a  shareholder.  Thus, the risk
of a shareholder incurring financial loss on account of shareholder liability is
limited to  circumstances  in which the Trust itself would be unable to meet its
obligations.  The  Trust  has  been  advised  by  counsel  that  the risk of any
shareholder  incurring any liability for the obligations of a Trust is extremely
remote. Wright does not consider this risk to be material.

THE FUND AND ITS INVESTMENT OBJECTIVE AND POLICIES

     The fund's objective is high total return (consisting of price appreciation
and high  income)  with  reduced  risk.  The fund  seeks to meet its  investment
objective by  allocating  its assets among the Blue Chip Funds  described in the
Prospectus.  Capitalized  terms used in the Statement of Additional  Information
have the same meaning as in the Prospectus.

INVESTMENT POLICIES AND OTHER INFORMATION ABOUT THE UNDERLYING BLUE CHIPS

     The fund will concentrate its investments in the underlying Blue Chip Funds
which are mutual funds.  Mutual funds pool the investments of many investors and
use  professional  management  to select and  purchase  securities  of different
issuers for their  portfolios.  Any  investment in a mutual fund involves  risk.
Even though the fund may invest in a number of the  underlying  Blue Chip Funds,
this investment strategy cannot eliminate  investment risk.  Investing in mutual
funds through a fund involves additional and duplicative expenses that would not
be present if an investor  were to make a direct  investment  in the  underlying
funds.

     Under certain  circumstances  an underlying Blue Chip Fund may determine to
make payment of a redemption  by the fund (wholly or in part) by a  distribution
in kind of securities from its portfolio,  instead of in cash. As a result,  the
fund may hold securities  distributed by an underlying Blue Chip Fund until such
time as Wright  determines it  appropriate to dispose of such  securities.  Such
disposition will impose additional costs on the fund.

     The types of securities  that may be acquired by the  underlying  Blue Chip
Funds and the various investment techniques which they may employ, including the
risks  associated with these  investments,  are described  below.  References to
"fund" and "funds" in this section only refer to the underlying Blue Chip Funds.
<PAGE>

EQUITY SECURITIES

     Common  Stocks.  Common stocks are shares of a corporation  or other entity
that  entitle the holder to a pro rata share of the profits of the  corporation,
if any, without  preference over any other shareholder or class of shareholders,
including  holders of the  entity's  preferred  stock and other  senior  equity.
Common  stock  usually  carries  with it the  right  to vote and  frequently  an
exclusive right to do so.

     Preferred  Stocks and Convertible  Securities.  Convertible debt securities
and preferred stock entitle the holder to acquire the issuer's stock by exchange
or purchase for a predetermined rate. Convertible securities are subject both to
the credit and interest rate risks  associated with fixed income  securities and
to the stock market risk associated  with equity  securities.  Convertible  debt
securities  in  which  the  fund  invests  generally  are  rated  at the time of
investment in one of the top two rating  categories  by a nationally  recognized
rating organization or their unrated equivalent.

     Foreign Securities. Wright International Blue Chip Equities Fund may invest
in  foreign  securities.  Investing  in  securities  of foreign  governments  or
securities issued by companies whose principal  business  activities are outside
the United States may involve  significant  risks not  associated  with domestic
investments. It is anticipated that in most cases, the best available market for
foreign securities will be on exchanges or in  over-the-counter  markets located
outside  the  U.S.   Foreign  stock   markets,   while  growing  in  volume  and
sophistication,  are generally not as developed as those in the U.S.  Securities
of some foreign issuers (particularly those located in developing countries) may
be less liquid and more volatile than securities of comparable  U.S.  companies.
In addition, foreign brokerage commissions are generally higher than commissions
on securities traded in the U.S. and may be non-negotiable. In general, there is
less overall  governmental  supervision and regulation of securities  exchanges,
brokers and listed companies than in the U.S.

     The  limited  liquidity  of certain  foreign  markets may affect the fund's
ability to accurately value its assets invested in such market. In addition, the
settlement  systems of certain  foreign  countries are less  developed  than the
U.S.,  which may  impede the fund's  ability to effect  portfolio  transactions.
There is generally less publicly available  information about foreign companies,
particularly  those not subject to the disclosure and reporting  requirements of
the U.S.  securities  laws.  Foreign  issuers are generally not bound by uniform
accounting,  auditing and financial reporting  requirements  comparable to those
applicable to domestic issuers.  Investments in foreign  securities also involve
the  risk  of  possible  adverse  changes  in  exchange   control   regulations,
expropriation or confiscatory taxation,  limitation on removal of funds or other
assets of the fund,  political or financial  instability or diplomatic and other
developments  which  could  affect  such  investments.   Further,  economies  of
particular  countries or areas of the world may differ  favorably or unfavorably
from the economy of the U.S.

     Foreign  Currency  Exchange  Transactions.  Investments  in  securities  of
foreign  governments  and companies  whose  principal  business  activities  are
located  outside of the United  States will  frequently  involve  currencies  of
foreign  countries.  In addition,  assets of the fund may temporarily be held in
bank  deposits  in  foreign  currencies  during  the  completion  of  investment
programs.  Therefore,  the  value of the  fund's  assets,  as  measured  in U.S.
dollars, may be affected favorably or unfavorably by changes in foreign currency
exchange rates and exchange  control  regulations.  Although the fund values its
assets daily in U.S.  dollars,  the fund does not intend to convert its holdings
of foreign  currencies into U.S.  dollars on a daily basis. The fund may conduct
its foreign currency exchange  transactions on a spot (i.e.,  cash) basis at the
spot rate  prevailing in the foreign  currency  exchange  market.  The fund will
convert  currency  on a spot  basis  from time to time and will  incur  costs in
connection with such currency  conversion.  Although foreign exchange dealers do
not  charge  a fee for  conversion,  they  do  realize  a  profit  based  on the
difference  (the  "spread")  between  the  prices at which  they are  buying and
selling various currencies.  Thus, a dealer may offer to sell a foreign currency
to the fund at one rate,  while  offering a lesser rate of  exchange  should the
fund  desire to resell that  currency to the dealer.  The funds do not intend to
speculate in foreign currency exchange rates.

     As an alternative to spot  transactions,  the fund may enter into contracts
to purchase or sell foreign currencies at a future date ("forward" contracts) or
purchase currency call or put options. A forward contract involves an obligation
to  purchase  or sell a specific  currency  at a future  date and price fixed by
agreement  between the parties at the time of entering into the contract.  These
contracts are traded in the interbank market conducted directly between currency
traders (usually large commercial banks) and their customers. A forward contract
generally involves no deposit  requirement and no commissions are charged at any
stage for  trades.  The funds  intend to enter into such  contracts  only on net
terms. The purchase of a put or call option is an alternative to the purchase or
sale of forward  contracts and will be used if the option premiums are less then
those in the forward contract market.

     The funds may enter into forward  contracts  only under two  circumstances.
First, when a fund enters into a contract for the purchase or sale of a security
quoted or dominated in a foreign  currency,  it may desire to "lock in" the U.S.
dollar price of the security.  This is  accomplished  by entering into a forward
contract for the purchase or sale,  for a fixed amount of U.S.  dollars,  of the
amount of foreign  currency  involved  in the  underlying  security  transaction
("transaction hedging"). Such forward contract transactions will enable the fund
to protect  itself  against a possible loss  resulting from an adverse change in

<PAGE>

the relationship between the U.S. dollar and the subject foreign currency during
the period  between the date the  security is  purchased or sold and the date of
payment for the security.

     Second,  when Wright  believes  that the currency of a  particular  foreign
country may suffer a substantial  decline against the U.S. dollar,  the fund may
enter into a forward contract to sell, for a fixed amount of U.S.  dollars,  the
amount  of  foreign  currency  approximating  the  value  of  some or all of the
securities quoted or denominated in such foreign currency.  The precise matching
of the forward  contract  amounts and the value of the securities  involved will
not  generally  be  possible.  The future  value of such  securities  in foreign
currencies  will change as a consequence of  fluctuations in the market value of
those  securities  between the date the forward contract is entered into and the
date  it  matures.   The   projection  of  currency   exchange   rates  and  the
implementation  of a short-term  hedging  strategy are highly  uncertain.  As an
operating  policy,  the fund does not intend to enter into forward contracts for
such hedging  purposes on a regular or continuous  basis, and will not do so if,
as a result,  more than 50% of the value of the  fund's  total  assets  would be
committed to the  consummation of such  contracts.  The fund will also not enter
into such forward  contracts or maintain a net exposure to such contracts if the
contracts  would  obligate the fund to deliver an amount of foreign  currency in
excess of the value of the fund's securities or other assets denominated in that
currency.

     The fund's  custodian will place cash or liquid  securities in a segregated
account.  The amount of such  segregated  assets  will be at least  equal to the
value of the  fund's  total  assets  committed  to the  consummation  of forward
contracts  involving  the  purchase  of  forward  currency.  If the value of the
securities  placed  in the  segregated  account  declines,  additional  cash  or
securities  will be placed in the  account on a daily basis so that the value of
the account will equal the amount of the fund's commitments with respect to such
contracts.

     The fund  generally  will not enter into a forward  contract with a term of
greater than one year. At the maturity of a forward contract, the fund may elect
to sell the  portfolio  security  and make  delivery  of the  foreign  currency.
Alternatively,  the fund may retain the security and terminate  its  contractual
obligation to deliver the foreign currency by purchasing an identical offsetting
contract from the same currency trader.

     It is impossible  to forecast with  precision the market value of portfolio
securities  at the  expiration  of a forward  contract.  Accordingly,  it may be
necessary  for the fund to  purchase  additional  foreign  currency  on the spot
market (and bear the expense of such  purchase)  if the fund intends to sell the
security and the market value of the security is less than the amount of foreign
currency that the fund is obligated to deliver.  Conversely, it may be necessary
to sell on the spot market some of the foreign  currency  received upon the sale
of the  portfolio  security  if its market  value  exceeds the amount of foreign
currency that the fund is obligated to deliver.

     If the fund retains the  portfolio  security  and engages in an  offsetting
transaction,  the fund will incur a gain or a loss (as  described  below) to the
extent  that there has been a change in  forward  contract  prices.  If the fund
engages  in an  offsetting  transaction,  it may  subsequently  enter into a new
forward  contract to sell the foreign  currency.  Should forward contract prices
decline  during  the  period  between  the date the fund  enters  into a forward
contract  for the sale of the  foreign  currency  and the date it enters into an
offsetting  contract  for the  purchase of the foreign  currency,  the fund will
realize a gain to the  extent  that the price of the  currency  it has agreed to
sell exceeds the price of the currency it has agreed to purchase. Should forward
contract  prices  increase,  the fund will  suffer a loss to the extent that the
price of the  currency  it has  agreed  to  purchase  exceeds  the  price of the
currency it has agreed to sell.

     The fund will not speculate in forward  contracts and will limit its use of
such contracts to the transactions  described above. Of course,  the fund is not
required  to  enter  into  such  transactions  with  respect  to  its  portfolio
securities  and will  not do so  unless  deemed  appropriate  by its  investment
adviser.  This method of protecting the value of the fund's securities against a
decline  in the  value of a  currency  does not  eliminate  fluctuations  in the
underlying  prices of the securities.  It simply  establishes a rate of exchange
which the fund can  achieve at some future  time.  Additionally,  although  such
contracts tend to minimize the risk of loss due to a decline in the value of the
hedged  currency,  they also tend to limit any  potential  gain  which  might be
realized if the value of such currency increases.

FIXED INCOME SECURITIES

     Generally.  Investments in fixed income securities may subject the fund to
risks, including the following.

     Interest Rate Risk. When interest rates decline,  the market value of fixed
income securities tends to increase.  Conversely,  when interest rates increase,
the market value of fixed income securities tends to decline.  The volatility of
a security's  market value will differ  depending upon the security's  duration,
the issuer and the type of instrument.
<PAGE>

     Default  Risk/Credit  Risk.  Investments  in fixed  income  securities  are
subject  to the risk  that the  issuer  of the  security  could  default  on its
obligations,  causing a fund to sustain  losses on such  investments.  A default
could impact both interest and principal payments.

     Call Risk and Extension  Risk.  Fixed income  securities  may be subject to
both call risk and extension risk. Call risk exists when the issuer may exercise
its right to pay principal on an obligation earlier than scheduled,  which would
cause cash flows to be returned  earlier than expected.  This typically  results
when interest rates have declined and a fund will suffer from having to reinvest
in lower yielding securities. Extension risk exists when the issuer may exercise
its right to pay principal on an obligation  later than  scheduled,  which would
cause cash flows to be returned later than expected. This typically results when
interest  rates have  increased,  and a fund will suffer from the  inability  to
invest in higher yield securities.

     Corporate Debt  Obligations.  Corporate debt obligations are subject to the
risk of an issuer's  inability to meet  principal  and interest  payments on the
obligations  and may also be subject to price  volatility due to such factors as
market interest rates,  market perception of the  creditworthiness of the issuer
and general market liquidity.

     U.S.  Government  Securities.  U.S. Government  securities include:  bills,
certificates of indebtedness, and notes and bonds issued by the U.S. Treasury or
by agencies or instrumentalities  of the U.S.  Government.  Some U.S. Government
securities,  such as U.S.  Treasury  bills and bonds,  are supported by the full
faith and credit of the U.S. Treasury;  others are supported by the right of the
issuer to borrow from the U.S.  Treasury;  others,  such as those of the Federal
National Mortgage Association,  are supported by the discretionary  authority of
the U.S. Government to purchase the agency's obligations;  still others, such as
those of the  Student  Loan  Marketing  Association  and the  Federal  Home Loan
Mortgage  Corporation  ("FHLMC"),  are  supported  only  by  the  credit  of the
instrumentality.   Mortgage  participation  certificates  issued  by  the  FHLMC
generally  represent  ownership  interests in a pool of fixed-rate  conventional
mortgages.  Timely  payment of principal and interest on these  certificates  is
guaranteed  solely by the issuer of the  certificates.  Other  investments  will
include   Government   National   Mortgage   Association   Certificates   ("GNMA
Certificates"), which are mortgage-backed securities representing part ownership
of a pool of mortgage loans on which timely payment of interest and principal is
guaranteed by the full faith and credit of the U.S.  Government.  While the U.S.
Government   guarantees   the  payment  of   principal   and  interest  on  GNMA
Certificates,  the market value of the  securities  is not  guaranteed  and will
fluctuate.

     Mortgage-Related  Securities.  Wright  Total  Return  Bond Fund and  Wright
Current  Income  Fund  may  invest  in  mortgage-related  securities,  including
collateralized    mortgage    obligations    ("CMOs")   and   other   derivative
mortgage-related  securities. These securities will either be issued by the U.S.
Government or one of its agencies or instrumentalities  or, if privately issued,
supported by mortgage collateral that is insured, guaranteed or otherwise backed
by the U.S.  Government  or its agencies or  instrumentalities.  THE FUNDS DO NO
INVEST IN THE RESIDUAL CLASSES OF CMOS,  STRIPPED  MORTGAGE-RELATED  SECURITIES,
LEVERAGED FLOATING RATE INSTRUMENTS OR INDEXED SECURITIES.

     Mortgage-related  securities represent  participation interests in pools of
adjustable and fixed  mortgage  loans.  Unlike  conventional  debt  obligations,
mortgage-related  securities  provide monthly  payments derived from the monthly
interest  and  principal  payments  (including  any  prepayments)  made  by  the
individual borrowers on the pooled mortgage loans. The mortgage loans underlying
mortgage-related securities are generally subject to a greater rate of principal
prepayments  in a declining  interest rate  environment  and to a lesser rate of
principal prepayments in an increasing interest rate environment.  Under certain
interest  and  prepayment  rate  scenarios,  a fund may fail to recover the full
amount of its investment in mortgage-related  securities purchased at a premium,
notwithstanding  any direct or indirect  governmental or agency  guarantee.  The
fund may realize a gain on mortgage-related  securities purchased at a discount.
Since  faster  than  expected  prepayments  must  usually be  invested  in lower
yielding  securities,   mortgage-related  securities  are  less  effective  than
conventional bonds in "locking in" a specified interest rate.  Conversely,  in a
rising interest rate  environment,  a declining  prepayment rate will extend the
average life of many mortgage-related securities.  Extending the average life of
a mortgage  related  security  increases the risk of depreciation  due to future
increases in market interest rates.

     A  fund's   investments   in   mortgage-related   securities   may  include
conventional  mortgage  pass-through  securities and certain classes of multiple
class CMOs.  Senior CMO classes will  typically  have priority over residual CMO
classes  as to  the  receipt  of  principal  and/or  interest  payments  on  the
underlying  mortgages.  The CMO  classes  in  which a fund  may  invest  include
sequential and parallel pay CMOs,  including planned  amortization class ("PAC")
and target amortization class ("TAC") securities.

     Different  types of  mortgage-related  securities  are subject to different
combinations of prepayment,  extension, interest rate and/or other market risks.
Conventional  mortgage  pass-through  securities  and  sequential  pay  CMOs are
subject to all of these risks,  but are typically not leveraged.  PACs, TACs and
other senior  classes of sequential  and parallel pay CMOs involve less exposure

<PAGE>

to  prepayment,  extension  and interest  rate risk than other  mortgage-related
securities,  provided that prepayment  rates remain within  expected  prepayment
ranges or "collars."

MONEY MARKET INSTRUMENTS

     CERTIFICATES OF DEPOSIT - are  certificates  issued against funds deposited
in a bank, are for a definite  period of time,  earn a specified rate of return,
and are normally negotiable.

     BANKERS'  ACCEPTANCEs - are short-term  credit  instruments used to finance
the import,  export,  transfer or storage of goods.  They are termed  "accepted"
when a bank guarantees their payment at maturity.

     COMMERCIAL  PAPER - refers to promissory  notes issued by  corporations  in
order to finance their short-term credit needs.

     FINANCE  COMPANY  PAPER - refers to  promissory  notes  issued  by  finance
companies in order to finance their short-term credit needs.

     CORPORATE  OBLIGATIONS - include bonds and notes issued by corporations in
order to finance longer-term credit needs.

     Forward  Commitments  and  When-Issued  Securities.  A  fund  may  purchase
when-issued  securities and make contracts to purchase or sell  securities for a
fixed price at a future date beyond customary settlement time. Alternatively,  a
fund  may  enter  into  offsetting  contracts  for the  forward  sale  of  other
securities  that it  owns.  Securities  purchased  or sold on a  when-issued  or
forward  commitment basis involve a risk of loss if the value of the security to
be  purchased  declines  prior  to the  settlement  date or if the  value of the
security to be sold increases prior to the settlement date.

     Securities  are  frequently  offered  on a  "when-issued"  basis.  When  so
offered,  the price, which is generally expressed in terms of yield to maturity,
is fixed at the time the  commitment  to  purchase  is made,  but  delivery  and
payment for the when-issued securities may take place at a later date. Normally,
the settlement date occurs 15 to 90 days after the date of the transaction.  The
payment obligation and the interest rate that will be received on the securities
are fixed at the time a fund enters  into the  purchase  commitment.  During the
period between  purchase and  settlement,  no payment is made by the fund to the
issuer and no interest  accrues to the fund. To the extent that assets of a fund
are held in cash pending the  settlement of a purchase of  securities,  the fund
would  earn no  income;  however,  it is  intended  that the funds will be fully
invested to the extent  practicable  and subject to the policies  stated  above.
While forward  commitments and  when-issued  securities may be sold prior to the
settlement  date,  it is intended that such  securities  will be purchased for a
fund with the purpose of  actually  acquiring  them unless a sale  appears to be
desirable  for  investment  reasons.  At  the  time  a  commitment  to  purchase
securities on a when-issued  basis is made for a fund, the  transaction  will be
recorded and the value of the security  reflected in determining  the fund's net
asset value.  A fund will  establish a  segregated  account in which a fund that
purchases  securities  on a  when-issued  basis  will  maintain  cash and liquid
securities  equal in value to commitments  for  when-issued  securities.  If the
value of the securities placed in the separate account declines, additional cash
or  securities  will be placed in the account on a daily basis so that the value
of  the  account  will  at  least  equal  the  amount  of a  fund's  when-issued
commitments.  Such segregated securities either will mature or, if necessary, be
sold on or before the  settlement  date.  Securities  purchased on a when-issued
basis and the  securities  held by a fund are  subject to changes in value based
upon the public's  perception of the credit worthiness of the issuer and changes
in the level of interest rates (which will generally  result in both changing in
value in the same way, i.e., both experiencing  appreciation when interest rates
decline and  depreciation  when interest rates rise).  Therefore,  to the extent
that a fund remains  substantially  fully  invested at the same time that it has
purchased  securities on a when-issued basis, there will be greater fluctuations
in the market  value of the fund's net assets than if cash were solely set aside
to pay for when-issued securities.

     Lending Portfolio Securities. A fund may seek to increase income by lending
portfolio securities to broker-dealers or other institutional  borrowers.  Under
present  regulatory  policies of the  Securities and Exchange  Commission,  such
loans are required to be secured  continuously  by  collateral in cash or liquid
assets held by the fund's  custodian  and  maintained  on a current  basis at an
amount at least equal to the market value of the securities  loaned,  which will
be marked to market daily.  Cash  equivalents  include  certificates of deposit,
commercial paper and other short-term money market  instruments.  The fund would
have the right to call a loan and obtain the securities loaned at any time on up
to five  business  days'  notice.  The fund would not have the right to vote any
securities  having voting rights during the existence of a loan,  but would call
the loan in  anticipation  of an important vote to be taken among holders of the
securities or the giving or  withholding  of their consent on a material  matter
affecting the investment.

     During  the  existence  of a loan,  a fund will  continue  to  receive  the
equivalent  of the  interest or dividends  paid by the issuer on the  securities
loaned and will also receive a fee, or all or a portion of the interest, if any,
on investment of the  collateral.

<PAGE>

However,  the  fund  may at the same  time  pay a  transection  fee to such
borrowers and administrative  expenses,  such as finders' fees to third parties.
As with other  extensions of credit there are risks of delay in recovery or even
loss of rights in the securities  loaned if the borrower of the securities fails
financially. However, the loans will be made only to organizations deemed by the
Investment  Adviser to be of good  standing  and when,  in the  judgment  of the
Investment Adviser,  the consideration which can be earned from securities loans
of this type  justifies  the  attendant  risk.  The  financial  condition of the
borrower  will be monitored by the  Investment  Adviser on an ongoing  basis and
collateral  values  will be  continuously  maintained  at no less  than  100% by
"marking to market" daily. If the Investment  Adviser decides to make securities
loans,  it is intended that the value of the  securities  loaned would no exceed
30% of the fund's total assets.

     Repurchase  Agreements.  A fund may enter into  repurchase  agreements only
with large,  well-capitalized  banks or government  securities dealers that meet
Wright's credit standards.  Repurchase  agreements  involve the purchase of U.S.
Government securities or of other high-quality,  short-term debt obligations. At
the same time a fund  purchases  the  security,  it  resells it to the vendor (a
member bank of the Federal Reserve System or recognized  securities dealer), and
is obligated to redeliver the security to the vendor on an  agreed-upon  date in
the future.  The resale price is in excess of the purchase price and reflects an
agreed-upon market rate unrelated to the coupon rate on the purchased  security.
These transactions, which are like short-term loans, afford an opportunity for a
fund to earn a return on cash which is only temporarily available. A fund's risk
is the ability of the vendor to pay an  agreed-upon  sum upon the delivery date,
and each fund believes the risk is limited to the difference  between the market
value of the security and the  repurchase  price  provided for in the repurchase
agreement. However, bankruptcy or insolvency proceedings affecting the vendor of
the  security  which  is  subject  to the  repurchase  agreement,  prior  to the
repurchase, may result in a delay in a fund being able to resell the security.

     In all cases when entering into repurchase  agreements with other than FDIC
insured depository institutions,  the funds will take physical possession of the
underlying  collateral  security,  or will receive  written  confirmation of the
purchase of the collateral  security and a custodial or safekeeping receipt from
a third  party  under a  written  bailment  for  hire  contract,  or will be the
recorded owner of the collateral security through the Federal Reserve Book-Entry
System.

     Defensive  Investments.  During periods of unusual market conditions,  when
Wright believes that investing for temporary  defensive purposes is appropriate,
all or a  portion  of a  fund's  assets  may be  held in  cash  or  invested  in
short-term  obligations.  Short-term  obligations include but are not limited to
short-term  obligations issued or guaranteed as to interest and principal by the
U.S. Government or any agency or instrumentality  thereof (including  repurchase
agreements  collateralized  by such  securities);  commercial paper which at the
date of  investment  is rated A-1 by S&P or P-1 by Moody's,  or, if not rated by
such  rating   organizations,   is  deemed  by  Wright  pursuant  to  procedures
established by the Trustees to be of comparable  quality;  short-term  corporate
obligations and other debt instruments which at the date of investment are rated
AA or better by S&P or Aa or better by Moody's  or, if  unrated  by such  rating
organizations,  are deemed by Wright  pursuant to procedures  established by the
Trustees to be of comparable  quality;  and  certificates  of deposit,  bankers'
acceptances  and time deposits of domestic  banks which are  determined to be of
high quality by Wright  pursuant to procedures  established  by the Trustees.  A
fund may  invest  in  instruments  and  obligations  of banks  that  have  other
relationships with the fund, Wright or Eaton Vance Management, the administrator
("Eaton  Vance"  or  "Administrator").  No  preference  will  be  shown  towards
investing in banks which have such relationships.

INVESTMENT RESTRICTIONS

     The following investment restrictions have been adopted by the fund and may
be changed  only by the vote of a  majority  of the  fund's  outstanding  voting
securities,  which as used in this Statement of Additional Information means the
lesser of (a) 67% of the  shares of the fund if the  holders of more than 50% of
the shares are present or represented at the meeting or (b) more than 50% of the
shares of the fund. Accordingly, the fund may not:

     (1)     With respect to 75% of the total  assets of the fund,  purchase the
             securities of any issuer if such purchase at the time thereof would
             cause more than 5% of its total assets  (taken at market  value) to
             be  invested  in  the  securities  of  such  issuer,   or  purchase
             securities of any issuer if such purchase at the time thereof would
             cause more than 10% of the total voting  securities  of such issuer
             to be held by the fund, except that this restriction does not apply
             to  obligations  issued or guaranteed by the U.S.  Government,  its
             agencies or  instrumentalities  and securities of other  investment
             companies;

     (2)     Borrow money or issue senior  securities except as permitted by the
             Investment Company Act of 1940. In addition, the fund may not issue
             bonds, debentures or senior equity securities, other than shares of
             beneficial interest;

     (3)     Purchase securities on margin (but the fund may obtain such short-
             term credits as may be necessary for the clearance of purchases
             and sales of securities);
<PAGE>

     (4)     Underwrite or participate in the marketing of securities of others;

     (5)     Make an  investment  in any one industry if such  investment  would
             cause  investments  in such  industry to equal or exceed 25% of the
             fund's  total  assets  taken  at  market  value at the time of such
             investment  (other than (i) securities  issued or guaranteed by the
             U.S.  Government  or its  agencies or  instrumentalities)  and (ii)
             securities of other investment companies;

     (6)     Purchase or sell real  estate,  although it may  purchase  and sell
             securities  which are  secured  by real  estate and  securities  of
             companies which invest or deal in real estate;

     (7)     Purchase  or  sell  commodities  or  commodity  contracts  for  the
             purchase or sale of physical commodities,  except that the fund may
             purchase and sell financial futures contracts, options on financial
             futures contracts and all types of currency contracts; or

     (8)     Make  loans to any  person  except by (a) the  acquisition  of debt
             securities  and making  portfolio  investments  (b)  entering  into
             repurchase agreements or (c) lending portfolio securities.

     The fund has adopted the following  investment  policy which may be changed
without  approval  by the  fund's  shareholders.  As a matter of  nonfundamental
policy,  the fund  will not  invest  more  than 15% of net  assets  in  illiquid
investments. If the fund's holdings of illiquid securities exceed 15% of its net
assets,  the fund will take steps  necessary  to reduce  these  holdings  in its
ordinary course of business. In addition,  the fund will not purchase securities
when bank borrowing exceeds 5% of total assets.

     Except for the fund's  investment  policies with respect to borrowing money
and investing in illiquid securities,  if a percentage  restriction contained in
the fund's investment policies is adhered to at the time of investment,  a later
increase or decrease in the  percentage  resulting from a change in the value of
portfolio securities or the fund's net assets will not be considered a violation
of such restriction.

CONTROL PERSONS AND PRINCIPAL HOLDERS OF SHARES

     As of the date of this  Statement  of  Additional  Information,  all of the
outstanding shares of the fund are owned by Wright.

INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES

     The  fund  has  engaged  Wright  to act as the  fund's  investment  adviser
pursuant  to  an  Investment   Advisory   Contract  (the  "Investment   Advisory
Contract").  Wright,  acting  under the  general  supervision  of the  trustees,
furnishes the fund with investment advice and management services,  as described
below. The School for Ethical Education,  1000 Lafayette Boulevard,  Bridgeport,
CT 06604, may be considered a controlling  person of Wright's parent,  Winthrop,
and Wright by reason of its ownership of more than 25% of the outstanding shares
of Winthrop.

     Pursuant to the  Investment  Advisory  Contract,  Wright will carry out the
investment and reinvestment of the assets of the fund, will furnish continuously
an investment  program with respect to the fund, will determine which securities
should be purchased,  sold or exchanged and will implement such  determinations.
Wright will be solely  responsible  for evaluating the investment  merits of the
fund's portfolio investments.  Wright will furnish to the fund investment advice
and management  services,  office space,  equipment and clerical personnel,  and
investment advisory,  statistical and research facilities.  In addition,  Wright
has arranged for certain members of the Eaton Vance and Wright  organizations to
serve without  salary as officers or trustees of the Trust.  In return for these
services,  the fund is obligated to pay a monthly advisory fee calculated at the
rate set forth in the fund's current Prospectus.

     The fund has engaged Eaton Vance to act as its administrator pursuant to an
Administration  Agreement. For its services under the Administration  Agreement,
Eaton Vance receives monthly administration fees at the annual rate of 0.02% of
the fund's average net assets.

     Eaton Vance is a business trust  organized under  Massachusetts  law. Eaton
Vance,  Inc.  ("EV")  serves as trustee of Eaton  Vance.  Eaton Vance and EV are
wholly  owned  subsidiaries  of Eaton  Vance  Corporation  ("EVC"),  a  Maryland
corporation and publicly held holding company.  EVC through its subsidiaries and
affiliates  engages  primarily  in  investment  management,  administration  and
marketing  activities.  The  Directors of EVC are James B.  Hawkes,  Benjamin A.
Rowland, Jr. , John G.L. Cabot, John M. Nelson, Vincent M. O'Reilly and Ralph Z.
Sorenson.  All of the issued and outstanding  shares of Eaton Vance are owned by
EVC. All shares of the outstanding Voting Common Stock of EVC are deposited in a
Voting Trust, the Voting Trustees of which are Messrs.  Hawkes and Rowland, Alan
R. Dynner, Thomas E. Faust, Jr., Thomas J. Fetter, Duncan W. Richardson, William
M. Steul and Wharton P. Whitaker.  The Voting Trustees have unrestricted  voting
rights for the election of Directors of EVC. All of the outstanding voting trust
receipts  issued under said Voting Trust are owned by certain of the officers of
Eaton Vance who are also officers, or officers and Directors of EVC and EV.

     The fund will be responsible  for all of its expenses not expressly  stated
to be payable  by Wright  under its  Investment  Advisory  Contract,  including,
without  limitation,  the fees and expenses of its custodian and transfer agent,
including  those incurred for determining the fund's net asset value and keeping
the fund's books; the cost of share certificates;  membership dues to investment
company  organizations;  brokerage  commissions  and fees;  fees and expenses of
registering its shares;  expenses of reports to shareholders,  proxy statements,
and other expenses of shareholders' meetings;  insurance premiums;  printing and
mailing  expenses;  interest,  taxes and corporate  fees;  legal and  accounting
expenses;  expenses of trustees not affiliated  with Eaton Vance or Wright;  and
investment  advisory and  administration  fees. The fund will also bear expenses
incurred  in  connection  with  litigation  in which the fund is a party and the
legal obligation the fund may have to indemnify the officers and trustees of the
Trust with respect thereto.

     The fund's Investment  Advisory Contract and Administration  Agreement will
remain in effect until February 28, 2001. The Investment  Advisory  Contract may
be continued  from year to year  thereafter  so long as such  continuance  after
February 28, 2001 is approved at least annually (i) by the vote of a majority of
the  trustees  who are not  "interested  persons"  of the Trust,  Eaton Vance or
Wright cast in person at a meeting specifically called for the purpose of voting
on such  approval  and (ii) by the board of trustees or by vote of a majority of
the outstanding shares of the fund. The fund's  Administration  Agreement may be
continued from year to year after February 28, 2001 so long as such  continuance
is approved  annually by the vote of a majority of the trustees.  Each agreement
may be terminated at any time without  penalty on sixty (60) days written notice
by the  board of  trustees  or  directors  of  either  party,  or by vote of the
majority of the  outstanding  shares of the fund.  Each agreement will terminate
automatically in the event of its assignment.  Each agreement  provides that, in
the absence of willful  misfeasance,  bad faith,  gross  negligence  or reckless
disregard of its  obligations  or duties to the fund under such agreement on the
part of Eaton Vance or Wright,  neither Eaton Vance nor Wright,  as the case may
be, will be liable to the fund for any loss incurred.

CUSTODIAN AND TRANSFER AGENT

     IBT, 200  Clarendon  Street,  Boston,  MA 02116,  acts as custodian for the
fund. IBT has the custody of all cash and securities of the fund,  maintains the

<PAGE>


BROKERAGE ALLOCATION

     Wright places the portfolio  security  transactions  for the fund, which in
some cases may be effected in block  transactions  which include other  accounts
managed by Wright.  Wright  provides  similar  services  directly for bank trust
departments  and other  investment  advisory  accounts.  Wright seeks to execute
portfolio  security  transactions  on the most  favorable  terms and in the most
effective manner possible.  In seeking best execution,  Wright will use its best
judgment in evaluating the terms of a transaction,  and will give  consideration
to various relevant factors,  including without  limitation the size and type of
the transaction,  the nature and character of the markets for the security,  the
confidentiality,  speed and  certainty of effective  execution  required for the
transaction,   the  reputation,   experience  and  financial  condition  of  the
broker-dealer and the value and quality of service rendered by the broker-dealer
in other  transactions,  and the  reasonableness of the brokerage  commission or
markup, if any.

     It is expected that on frequent  occasions there will be many broker-dealer
firms which will meet the foregoing  criteria for a particular  transaction.  In
selecting among such firms,  Wright may give  consideration to those firms which
supply  brokerage and research  services,  quotations and  statistical and other
information to Wright for its use in servicing its advisory accounts. Wright may
include  firms  which  purchase   investment  services  from  Wright.  The  term
"brokerage and research services" includes advice as to the value of securities,
the  advisability  of investing in,  purchasing or selling  securities,  and the
availability  of securities or purchasers or sellers of  securities;  furnishing
analyses  and  reports  concerning  issuers,  industries,  securities,  economic
factors and trends,  portfolio  strategy and the  performance  of accounts;  and
effecting  securities  transactions and performing  functions incidental thereto
(such as clearance and settlement).  Such services and information may be useful
and of value to Wright in servicing all or less than all of its accounts and the
services and  information  furnished by a particular firm may not necessarily be
used in connection  with the account which paid  brokerage  commissions  to such
firm.  The  advisory  fee  paid  by the  fund  to  Wright  is not  reduced  as a
consequence  of Wright's  receipt of such services and  information.  While such
services and  information  are not expected to reduce  Wright's  normal research
activities  and  expenses,  Wright  would,  through  use of  such  services  and
information,  avoid the additional expenses which would be incurred if it should
attempt to develop comparable services and information through its own staff.

     Under the fund's Investment Advisory Contract,  Wright has the authority to
pay commissions on portfolio  transactions  for brokerage and research  services
exceeding  that which other  brokers or dealers  might charge  provided  certain
conditions  are met. This authority  will not be exercised,  however,  until the
Prospectus or this Statement of Additional  Information has been supplemented or
amended to disclose the conditions under which Wright proposes to do so.

     The Investment  Advisory Contract expressly  recognizes the practices which
are  provided  for in Section  28(e) of the  Securities  Exchange Act of 1934 by
authorizing  the  selection  of a broker  or  dealer  which  charges  the fund a
commission  which is in excess of the  amount of  commission  another  broker or
dealer would have charged for effecting that  transaction if it is determined in
good faith that such  commission  was reasonable in relation to the value of the
brokerage and research services which have been provided.

PRICING OF SHARES

     For a description of how the fund values its shares, see "Information About
Your  Account  --  How  the  Fund  Values  its  Shares"  in the  fund's  current
Prospectus.  The fund values securities with a remaining  maturity of 60 days or
less by the amortized cost method.  The amortized cost method involves initially
valuing a security at its cost (or its fair market value on the  sixty-first day
prior to maturity) and thereafter  assuming a constant  amortization to maturity
of any  discount  or  premium,  without  regard to  unrealized  appreciation  or
depreciation in the market value of the security. Foreign securities in which an
underlying  fund may invest may be listed  primarily on foreign stock  exchanges
that my trade on days when the fund is not open for  business.  For this reason,
the net asset  value of an  underlying  fund's  portfolio  may be  significantly
affected by trading on days when an investor does not have access to the fund.

     The fund will not price its securities on the following  national holidays:
New Year's Day;  Martin  Luther King,  Jr. Day;  Presidents'  Day;  Good Friday;
Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day.

TAXES

     In order to qualify as a regulated  investment  company as described in the
Prospectus,  the fund must,  among other things,  (1) derive at least 90% of its
gross  income in each  taxable  year from  dividends,  interest,  payments  with
respect to securities loans,  gains from the sale or other disposition of stocks
or securities or foreign currencies,  or other income (including but not limited

<PAGE>

to gains  from  options  and  forward  contracts)  derived  with  respect to its
business  of  investing  in such  stocks or  securities  and (2)  diversify  its
holdings in compliance with the diversification  requirements of Subchapter M of
the Code so that, at the end of each quarter of the fund's  taxable year, (a) at
least 50% of the market value of the fund's total assets is represented by cash,
U.S.  Government  securities and other securities  limited in respect of any one
issuer to not more than 5% of the value of the fund's total  (gross)  assets and
to not more than 10% of the voting  securities of such issuer,  and (b) not more
than 25% of the value of its total  (gross)  assets is invested in securities of
any one issuer (other than U.S. Government  securities) or certain other issuers
controlled by the fund.

     As a regulated  investment company, the fund will not be subject to federal
income tax on net investment income and net capital gains (short and long-term),
if  any,  that  it  distributes  to  its  shareholders  if at  least  90% of its
investment  company  taxable  income (i.e.,  all of its net taxable income other
than the  excess,  if any, of net  long-term  capital  gain over net  short-term
capital  loss ("net  capital  gain"),  for the taxable  year is  distributed  in
accordance with applicable  timing  requirements,  but will be subject to tax at
regular corporate rates on any investment  company taxable income or net capital
gain that is not so distributed.  In general,  dividends will be treated as paid
when actually distributed,  except that dividends declared in October,  November
or December and made payable to  shareholders  of record in such a month will be
treated as having been received by  shareholders on December 31, if the dividend
is paid in the following  January.  The fund intends to satisfy the distribution
requirement  in each taxable  year.  The fund's  distributions  from  investment
company  taxable  income and net capital gain are generally  treated as ordinary
income and  long-term  capital  gain,  respectively,  under the Code.  Insurance
companies  should  consult  their  own tax  advisers  regarding  the  tax  rules
governing their treatment upon receipt of these  distributions  and the proceeds
of share redemptions (including exchanges).

     The  fund  will  not be  subject  to  federal  excise  tax  or the  related
distribution  requirements  for any taxable  year in which all of its shares are
held by segregated asset accounts of life insurance companies held in connection
with  variable  contracts  or  are  attributable  to  certain  "seed  money"  in
accordance with Section 4982(f) of the Code.

     Investment  by the  fund in the  stock  of a  "passive  foreign  investment
company"  may  cause  the  fund to  recognize  income  prior to the  receipt  of
distributions  from such a company or to become  subject to tax upon the receipt
of certain excess  distributions from, or upon disposition of its stock of, such
a company, although an election may generally be available that would ameliorate
some of these adverse tax consequences.

     The fund intends to comply with the diversification requirements imposed by
Section 817(h) of the Code and the regulations  thereunder.  These requirements,
which are in addition to the diversification requirements imposed on the fund by
the 1940 Act and  Subchapter M of the Code,  place  certain  limitations  on the
assets  of  each  separate   account  and,  because  Section  817(h)  and  those
regulations  treat the  assets of the fund as  assets  of the  related  separate
account,  the assets of the fund, that may be represented by any one, two, three
and four  investments.  Specifically,  the regulations  provide that,  except as
permitted by the "safe harbor"  described  below, as of the end of each calendar
quarter or within 30 days thereafter no more than 55% of the total assets of the
fund  may be  represented  by any one  investment,  no more  than 70% by any two
investments,  no more than 80% by any three  investments and no more than 90% by
any four  investments.  For this purpose,  all securities of the same issuer are
considered  a  single   investment,   and  each  U.S.   Government   agency  and
instrumentality is considered a separate issuer.  Section 817(h) provides,  as a
safe  harbor,  that a  separate  account  will be  treated  as being  adequately
diversified if the diversification requirements under Subchapter M are satisfied
and no more than 55% of the value of the  account's  total  assets  are cash and
cash items (including receivables), U.S. Government securities and securities of
other regulated investment  companies.  Failure by the fund to both qualify as a
regulated  investment company and satisfy the Section 817(h)  requirements would
generally  result in treatment of the variable  contract  holders  other than as
described in the applicable variable contract prospectus, including inclusion in
ordinary  income of income  accrued  under the contracts for the current and all
prior  taxable  years.   Any  such  failure  may  also  result  in  adverse  tax
consequences for the insurance company issuing the contracts.

     The Trust may therefore  find it necessary to take action to seek to ensure
that a Contract  continues  to qualify as a  Contract  under  federal  tax laws,
although the insurance  company that maintains each segregated  asset account is
responsible  for  ensuring  that the assets  held in that  account  satisfy  the
diversification  requirements  of Section  817(h) of the Code and the applicable
regulations  and the Trust  itself can  control  only the assets held within the
fund. The Trust, for example, may be required to alter the investment objectives
of the fund or substitute  the shares of one fund for those of another.  No such
change of investment  objectives or  substitution  of securities will take place
without notice to the shareholders of the affected fund.  Failure by the fund to
qualify as a regulated investment company would also subject the fund to federal
and possibly state taxation of its income and gains,  whether or not distributed
to shareholders, and distributions would generally be treated as ordinary income
to the extent of the fund's current or accumulated earnings and profits.

     The fund is not subject to Massachusetts corporate excise or franchise tax.
Provided  that the fund  qualifies as a regulated  investment  company under the
Code, it will also not be required to pay any Massachusetts income tax.

CALCULATION OF PERFORMANCE AND YIELD QUOTATIONS

     The average  annual total return of the fund is determined for a particular
period by calculating the actual dollar amount of investment  return on a $1,000
investment in the fund made at the maximum public offering price (i.e. net asset
value)  at  the  beginning  of the  period,  and  then  calculating  the  annual
compounded  rate of return which would  produce that amount.  Total return for a
period of one year is equal to the actual return of the fund during that period.
This calculation  assumes that all dividends and distributions are reinvested at
net asset value on the reinvestment dates during the period.

     The yield of the fund is computed by dividing its net investment income per
share earned during a recent 30-day period by the maximum  offering  price (i.e.
net asset  value)  per share on the last day of the  period  and  analyzing  the
resulting  figure.  Net  investment  income  per  share is  equal to the  fund's
dividends and interest earned during the period, with the resulting number being
divided by the  average  daily  number of shares  outstanding  and  entitled  to
receive dividends during the period.

     The fund's yield is calculated according to the following formula:
                                  6
             Yield =  2  [(a-b + 1)- 1]
                           ---
                           cd

Where:

     a = dividends and interest earned during the period.

     b = expenses accrued for the period (after reductions).

     c = the average daily number of shares outstanding during the period.

     d = the net asset value per share on the last day of the period.

     Yield and effective yield will be based on historical  earnings and are not
intended to indicate  future  performance.  Yield and effective  yield will vary
based on  changes in market  conditions  and the level of  expenses.  The fund's
yield or total  return may be compared to the  Consumer  Price Index and various
domestic  securities  indices.  The fund's yield or total return and comparisons
with these indices may be used in advertisements and in information furnished to
present or prospective shareholders.

     From time to time, in advertisements, in sales literature, or in reports to
shareholders,  the  past  performance  of the  fund  may be  illustrated  and/or
compared with that of other mutual funds with similar investment objectives, and
to stock or other relevant indices. In addition, the performance of the fund may
be compared to alternative  investment or savings  vehicles and/or to indexes or
indicators of economic activity,  e.g., inflation or interest rates. Performance
rankings and listings  reported in newspapers or national business and financial
publications,  such as  Barron's,  Business  Week,  Consumers  Digest,  Consumer
Reports, Financial World, Forbes, Fortune, Investors Business Daily, Kiplinger's
Personal  Finance  Magazine,  Money Magazine,  New York Times,  Smart Money, USA
Today, U.S. News and World Report, The Wall Street Journal and Worth may also be
cited (if the fund is listed in any such publication) or used for comparison, as
well as performance  listings and rankings from various other sources  including

Investment Management and Towers Data Systems, Inc.

     In addition,  from time to time  quotations  from articles  from  financial
publications such as those listed above may be used in advertisements,  in sales
literature,  or in reports to  shareholders  of the fund. The performance of the
fund will not be presented in  advertisements  or sales literature  without also
presenting the performance of the separate account.

Notes:

(1)  Wright Managed  Growth with Income Fund is a separate  series of The Wright
     Asset Allocation  Trust. A purchase of interests  therein at a price of $10
     per share was made by Wright Investors' Service (the "initial interests").

(2)  Offering  costs are being deferred and will be amortized on a straight line
     basis  over a  period  not  to  exceed  twelve  months,  commencing  on the
     effective  date of the Fund's  initial  offering of its shares.  The amount
     paid by the Fund on any withdrawal by the holders of the initial  interests
     of any of the respective  initial interests will be reduced by a portion of
     any unamortized offering costs,  determined by the proportion of the amount
     of  the  initial   interests   withdrawn  to  the  initial  interests  then
     outstanding.

                          Independent Auditors' Report




To the Trustees and Shareholder of
The Wright Asset Allocation Trust:


We have audited the  accompanying  statement of assets and liabilities of Wright
Managed  Growth  with  Income  Fund  (one  of the  series  of The  Wright  Asset
Allocation  Trust) (the Trust) as of May 19, 1999, and the related  statement of
operations  for the  period  then  ended.  These  financial  statements  are the
responsibility of the Trust's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audit.

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

In our  opinion,  such  financial  statements  present  fairly,  in all material
respects, the financial position of Wright Managed Growth with Income Fund as of
May 19,  1999,  and the results of its  operations  for the period then ended in
conformity with generally accepted accounting principles.

WRIGHT QUALITY RATINGS

     Wright Quality Ratings provide the means by which the fundamental  criteria
for the  measurement  of quality of an issuer's  securities for investment by an
underlying Blue Chip Fund can be objectively evaluated.

     Each rating is based on 32 individual measures of quality grouped into four
components: (1) Investment Acceptance, (2) Financial Strength, (3) Profitability
and Stability,  and (4) Growth. The total rating is three letters and a numeral.
The three letters measure (1) Investment Acceptance, (2) Financial Strength, and
(3) Profitability and Stability. Each letter reflects a composite measurement of
eight individual standards which are summarized as A: Outstanding, B: Excellent,
C: Good, D: Fair,  L: Limited,  and N: Not Rated.  The numeral  rating  reflects
Growth and is a composite of eight individual standards ranging from 0 to 20.

EQUITY SECURITIES

     INVESTMENT  ACCEPTANCE  reflects the acceptability of a security by and its
marketability  among  investors,  and the adequacy of the floating supply of its
common shares for the investment of substantial funds.

     FINANCIAL  STRENGTH  represents  the amount,  adequacy and liquidity of the
corporation's resources in relation to current and potential  requirements.  Its
principal  components  are  aggregate  equity  and total  capital,  the ratio of
invested equity capital to debt, the adequacy of net working capital,  its fixed
charges coverage ratio and other appropriate criteria.

     PROFITABILITY  AND  STABILITY   measures  the  record  of  a  corporation's
management  in  terms  of (1) the  rate and  consistency  of the net  return  on
shareholders'  equity capital  investment at corporate  book value,  and (2) the
profits or losses of the corporation  during generally adverse economic periods,
including its ability to withstand adverse financial developments.

     GROWTH per common share of the corporation's equity capital,  earnings, and
dividends - rather than the  corporation's  overall  growth of dollar  sales and
income.

     These  ratings  are  determined  by  specific   quantitative   formulae.  A
distinguishing  characteristic  of these  ratings is that The Wright  Investment
Committee  must  review and  accept  each  rating.  The  Committee  may reduce a
computed rating of any company, but may not increase it.

DEBT SECURITIES

     Wright ratings for commercial paper,  corporate bonds and bank certificates
of  deposit  consist  of  the  two  central   positions  of  the  four  position
alphanumeric  corporate equity rating. The two central positions represent those
factors which are most applicable to fixed income and reserve  investments.  The
first, Financial Strength, represents the amount, the adequacy and the liquidity
of  the   corporation's   resources   in  relation  to  current  and   potential
requirements.  Its principal  components are aggregate equity and total capital,
the ratios of (a) invested  equity  capital,  and (b) long-term  debt,  total of
corporate capital,  the adequacy of net working capital,  fixed charges coverage
ratio and other appropriate criteria. The second letter represents Profitability
and Stability and measures the record of a corporation's management in terms of:
(a) the rate and consistency of the net return on  shareholders'  equity capital
investment  at  corporate  book  value,  and (b) the  profits  and losses of the
corporation  during  generally  adverse  economic  periods,  and its  ability to
withstand adverse financial developments.

     The first  letter  rating of the Wright  four-part  alphanumeric  corporate
rating is not  included  in the  ratings  of  fixed-income  securities  since it
primarily  reflects the adequacy of the floating supply of the company's  common
shares for the investment of substantial funds. The numeric growth rating is not
included because this element is identified only with equity investments.

A-1 AND P-1 COMMERCIAL PAPER RATINGS BY S&P AND MOODY'S

     An S&P Commercial Paper Rating is a current assessment of the likelihood of
timely payment of debt having an original maturity of no more than 365 days.
<PAGE>

     `A':  Issues  assigned  this  highest  rating  are  regarded  as having the
greatest  capacity for timely  payment.  Issues in this category are  delineated
with the  numbers 1, 2, and 3 to indicate  the  relative  degree of safety.  The
`A-1'  designation  indicates that the degree of safety regarding timely payment
is either  overwhelming  or very  strong.  Those  issues  determined  to possess
overwhelming  safety  characteristics  will  be  denoted  with a plus  (+)  sign
designation.

     The commercial paper rating is not a  recommendation  to purchase or sell a
security.  The ratings are based on current information  furnished to S&P by the
issuer or obtained from other sources it considers reliable.  The ratings may be
changed,  suspended or withdrawn as a result of changes in or  unavailability of
such information.

     Issuers (or related  supporting  institutions)  rated P-1 by Moody's have a
superior  capacity  for  repayment of  short-term  promissory  obligations.  P-1
repayment capacity will normally be evidenced by the following characteristics:

     -  Leading market positions in well-established industries.

     -  High rates of return on funds employed.

     - Conservative capitalization structures with moderate reliance on debt and
       ample asset protection.

     - Broad margins in earnings  coverage of fixed  financial  charges and high
       internal cash generation.

     - Well-established  access to a range of  financial  markets  and  assured
       sources of alternate liquidity.

BOND RATINGS

     In  addition  to Wright  quality  ratings,  bonds or bond  insurers  may be
expected to have credit risk ratings assigned by the two major rating companies,
Moody's and S&P.  Moody's uses a  nine-symbol  system with Aaa being the highest
rating and C the lowest.  S&P uses a 10-symbol system that ranges from AAA to D.
Bonds within the top four  categories of Moody's (Aaa, Aa, A and Baa) and of S&P
(AAA, AA, A and BBB) are considered to be of investment-grade  quality. Bonds in
the lowest investment grade category (BBB) may have speculative characteristics.
Note that both S&P and Moody's  currently  give their highest  rating to issuers
insured by the American Municipal Bond Assurance  Corporation  (AMBAC) or by the
Municipal Bond Investors Assurance Corporation (MBIA).

     Bonds rated A by S&P have a strong  capacity to pay principal and interest,
although they are somewhat more  susceptible to the adverse effects of change in
circumstances and economic conditions than debt in higher-rated categories.  The
rating of AA is  accorded to issues  where the  capacity  to pay  principal  and
interest is very  strong and they  differ from AAA issues only in small  degree.
The AAA rating  indicates  an extremely  strong  capacity to pay  principal  and
interest.

     Bonds  rated A by Moody's are judged by Moody's to possess  many  favorable
investment  attributes  and are  considered  as upper medium grade  obligations.
Bonds  rated Aa by Moody's  are  judged by Moody's to be of high  quality by all
standards. Together with the Aaa group they comprise what are generally known as
high-grade  bonds.  They are rated  lower  than Aaa  bonds  because  margins  of
protection may not be as large or fluctuations of protective  elements may be of
greater degree or there may be other  elements  present which make the long-term
risks appear somewhat larger. Bonds rated Aaa by Moody's are judged to be of the
best quality.  Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issuers.

NOTE RATINGS

     In addition to Wright quality ratings, municipal notes and other short-term
loans may be assigned ratings by Moody's or S&P.

     Moody's  ratings  for  municipal  notes  and  other  short-term  loans  are
designated Moody's Investment Grade (MIG). This distinction is in recognition of
the differences  between short-term and long-term credit risk. Loans bearing the
designation  MIG 1 are  of the  best  quality,  enjoying  strong  protection  by
establishing  cash  flows of funds for their  servicing  or by  established  and
broad-based  access to the market for  refinancing,  or both.  Loans bearing the
designation MIG 2 are of high quality, with margins of protection ample although
not so large as in the preceding group.

     S&P's top ratings for  municipal  notes issued after July 29, 1984 are SP-1
and SP-2. the designation SP-1 indicates a very strong capacity to pay principal
and interest. A "+" is added for those issues determined to possess overwhelming
safety characteristics.
An "SP-2"  designation  indicates a  satisfactory  capacity to pay principal and
interest.
