(1)  The Management  Fee has  been  reduced to reflect the voluntary waiver of a

     The Total Institutional Shares Operating Expenses were 0.54% for the fiscal

     voluntary waiver of a portion of the management fee.

GENERAL INFORMATION
- --------------------------------------------------------------------------------

The  Trust was established as a Massachusetts business trust under a Declaration
of Trust dated January 3,  1984. The Declaration of  Trust permits the Trust  to
offer  separate series of shares  of beneficial interests representing interests
in separate portfolios  of securities. The  shares in any  one portfolio may  be
offered  in separate classes.  As of the  date of this  prospectus, the Board of
Trustees (the "Trustees") have established two  classes of shares of the  Trust,
known  as Institutional Shares and Institutional Service Shares. This prospectus
relates only to Institutional Shares.

Institutional Shares  ("Shares")  are  sold  primarily  to  accounts  for  which
financial  institutions act in a fiduciary or agency capacity, or other accounts
where the  financial institution  maintains master  accounts with  an  aggregate
investment  of  at least  $400 million  in  certain funds  which are  advised or
distributed by affiliates of Federated Investors. Shares are also made available
to financial intermediaries, public, and private organizations. An investment in
the Trust  serves  as  a convenient  means  of  accumulating an  interest  in  a
professionally  managed, diversified portfolio of  U.S. government securities. A
minimum initial investment of $25,000 over a 90-day period is required.

Shares are currently sold and redeemed at net asset value without a sales charge
imposed by the Trust.

INVESTMENT INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE

The investment  objective of  the Trust  is current  income. While  there is  no
assurance  that the Trust will achieve its investment objective, it endeavors to
do so by following the investment policies described in this prospectus.  Unless
otherwise  noted,  the investment  objective  and the  policies  and limitations
described below cannot be changed without approval of shareholders.

INVESTMENT POLICIES

The Trust  pursues its  investment  objective by  investing in  U.S.  government
securities  with remaining  maturities of 3  1/2 years  or less. As  a matter of
investment practice which can be changed without shareholder approval, the Trust
will maintain a dollar-weighted average portfolio maturity of 1 to 3 years.

ACCEPTABLE INVESTMENTS.   The  U.S.  government securities  in which  the  Trust
invests are either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities are limited to:

    - direct  obligations of  the U.S.  Treasury, such  as U.S.  Treasury bills,
      notes, and bonds; and

    - notes,  bonds,  and  discount  notes   of  U.S.  government  agencies   or
      instrumentalities, such as the: Farm Credit System, including the National
      Bank  for  Cooperatives, Farm  Credit Banks,  and Banks  for Cooperatives;
      Farmers Home Administration;  Federal Home Loan  Banks; Federal Home  Loan
      Mortgage  Corporation; Federal  National Mortgage  Association; Government
      National  Mortgage  Association;   Student  Loan  Marketing   Association;
      Tennessee Valley Au-

                                       3

      thority;  Export-Import  Bank  of  the  United  States;  Commodity  Credit
      Corporation;  Federal   Financing   Bank;  and   National   Credit   Union
      Administration.

Some  obligations issued or  guaranteed by agencies  or instrumentalities of the
U.S. government, such as Government National Mortgage Association  participation
certificates,  are backed by the full faith  and credit of the U.S. Treasury. No
assurances can be given that the U.S. government will provide financial  support
to  other agencies or instrumentalities, since it is not obligated to do so. The
instrumentalities are supported by:

    - the issuer's  right to  borrow an  amount limited  to a  specific line  of
      credit from the U.S. Treasury;

    - discretionary  authority  of  the  U.S.  government  to  purchase  certain
      obligations of an agency or instrumentality; or

    - the credit of the agency or instrumentality.

The prices of fixed  income securities fluctuate inversely  to the direction  of
interest rates.

    REPURCHASE  AGREEMENTS.   Repurchase  agreements  are arrangements  in which
    banks, broker/  dealers, and  other recognized  financial institutions  sell
    U.S. government securities or other securities to the Trust and agree at the
    time of sale to repurchase them at a mutually agreed upon time and price. To
    the  extent that the original seller does not repurchase the securities from
    the Trust, the  Trust could receive  less than the  repurchase price on  any
    sale of such securities.

    As  a matter of investment practice which can be changed without shareholder
    approval, the Trust  will not  invest more  than 15%  of its  net assets  in
    securities which are illiquid, including repurchase agreements providing for
    settlement in more than seven days after notice.

WHEN-ISSUED  AND  DELAYED  DELIVERY TRANSACTIONS.    As a  matter  of investment
practice, which  can be  changed  without shareholder  approval, the  Trust  may
purchase   securities  on  a  when-issued   or  delayed  delivery  basis.  These
transactions are  arrangements  in which  the  Trust purchases  securities  with
payment  and  delivery scheduled  for  a future  time.  The seller's  failure to
complete these  transactions  may cause  the  Trust to  miss  a price  or  yield
considered  to be advantageous.  Settlement dates may  be a month  or more after
entering into  these  transactions, and  the  market values  of  the  securities
purchased  may vary  from the  purchase prices.  Accordingly, the  Trust may pay
more/less than the market value of the securities on the settlement date.

The Trust may dispose of a commitment  prior to settlement if the adviser  deems
it  appropriate to do  so. In addition,  the Trust may  enter in transactions to
sell its purchase  commitments to  third parties  at current  market values  and
simultaneously acquire other commitments to purchase similar securities at later
dates.  The Trust may realize short-term profits or losses upon the sale of such
commitments.

PORTFOLIO TRANSACTIONS.  The Trust conducts portfolio transactions to accomplish
its investment objective as interest rates change, to invest new money  obtained
from  selling its shares, and to meet redemption requests. The Trust may dispose
of portfolio securities at  any time if it  appears that selling the  securities
will help the Trust achieve its investment objective.

borrowings.

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The  Trust is managed by a  Board of Trustees. The  Trustees
are responsible for managing the Trust's business affairs and for exercising all
the  Trust's powers  except those reserved  for the  shareholders. The Executive
Committee of the Board of Trustees handles the Board's responsibilities  between
meetings of the Board.

    fee equal to .40 of 1% of the Trust's average daily net assets. The  adviser
    has  also undertaken to reimburse the Trust for operating expenses in excess
    of  limitations  established  by  certain  states.  This  does  not  include
    reimbursement  to the Trust of any expenses incurred by shareholders who use
    the transfer agent's subaccounting facilities.

DISTRIBUTION OF INSTITUTIONAL SHARES

Federated Securities Corp. is the principal distributor for the Shares. It is  a
Pennsylvania  corporation organized on  November 14, 1969,  and is the principal
distributor for a number of investment companies. Federated Securities Corp.  is
a subsidiary of Federated Investors.

ADMINISTRATION OF THE TRUST

ADMINISTRATIVE  SERVICES.   Federated Administrative  Services, a  subsidiary of
Federated Investors, provides administrative  personnel and services  (including
certain  legal and financial reporting services) necessary to operate the Trust.
Federated Administrative Services provides these at an annual rate which relates
to the average aggregate daily net  assets of all funds advised by  subsidiaries
of Federated Investors ("Federated Funds") as specified below:

<TABLE>
<CAPTION>
              MAXIMUM                AVERAGE AGGREGATE DAILY NET ASSETS
         ADMINISTRATIVE FEE                OF THE FEDERATED FUNDS
        --------------------        ------------------------------------

             0.15 of 1%             on the first $250 million
            0.125 of 1%             on the next $250 million
             0.10 of 1%             on the next $250 million
            0.075 of 1%             on assets in excess of $750 million
</TABLE>

The  administrative  fee  received during  any  fiscal  year shall  be  at least
$125,000 per  portfolio  and  $30,000  per  each  additional  class  of  shares.
Federated  Administrative Services may choose voluntarily  to waive a portion of
its fee.

SHAREHOLDER SERVICES PLAN.   The Trust has adopted  a Shareholder Services  Plan
(the  "Services Plan") under which it may make  payments up to 0.25 of 1% of the
average daily net asset value of  the Trust to obtain certain personal  services
for  shareholders  and  the maintenance  of  shareholder  accounts ("shareholder
services"). The Trust  has entered  into a Shareholder  Services Agreement  with
Federated Shareholder Services, a subsidiary of Federated Investors, under which
Federated Shareholder Services will either perform shareholder services directly
or will select financial institutions to perform shareholder services. Financial
institutions  will  receive fees  based upon  shares owned  by their  clients or
customers. The schedules of such fees and the basis upon which such fees will be
paid will be determined from time to time by the Trust and Federated Shareholder
Services.

                                       6

CUSTODIAN.  State Street Bank and  Trust Company, ("State Street Bank")  Boston,
Massachusetts, is custodian for the securities and cash of the Trust.

TRANSFER  AGENT  AND DIVIDEND  DISBURSING  AGENT.   Federated  Services Company,
Pittsburgh, Pennsylvania  is transfer  agent for  the shares  of the  Trust  and
dividend disbursing agent for the Trust.

INDEPENDENT  AUDITORS.  The independent auditors for the Trust are Ernst & Young
LLP, Pittsburgh, Pennsylvania 15219.

NET ASSET VALUE
- --------------------------------------------------------------------------------

The Trust's net asset value per share fluctuates. The net asset value for Shares
is determined by adding the  interest of the Shares in  the market value of  all
securities and other assets of the Trust, subtracting the interest of the Shares
in  the liabilities of the Trust and  those attributable to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Institutional Shares may exceed that of Institutional Service Shares due to  the
variance  in daily net income realized by each class. Such variance will reflect
only accrued net  income to  which the shareholders  of a  particular class  are
entitled.

INVESTING IN INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------

SHARE PURCHASES

Shares  are  sold on  days on  which the  New  York Stock  Exchange is  open for
business. Shares may be purchased either by wire or mail.

To purchase  Shares,  open an  account  by calling  Federated  Securities  Corp.
Information needed to establish an account will be taken over the telephone. The
Trust reserves the right to reject any purchase request.

BY WIRE.  To purchase Shares by Federal Reserve wire, call the Trust before 4:00
p.m.  (Eastern  time)  to  place  an order.  The  order  is  considered received
immediately. Payment by  federal wire funds  must be received  before 3:00  p.m.
(Eastern  time)  on the  next business  day following  the order.  Federal funds
should be wired as follows: Federated Services Company c/o State Street Bank and
Trust Company,  Boston,  Massachusetts;  Attention:  EDGEWIRE;  For  Credit  to:
Federated  U.S.  Government  Securities Fund:  1-3  Years--Institutional Shares;
Trust Number (this number can be found on the account statement or by contacting
the Trust); Group Number or Wire Order Number; Nominee or Institution Name;  and
ABA Number 011000028.

BY  MAIL.  To  purchase Shares by mail,  send a check  made payable to Federated
U.S. Government Securities  Fund: 1-3 Years--Institutional  Shares to  Federated
Services  Company,  c/o State  Street  Bank and  Trust  Company, P.O.  Box 8602,
Boston, Massachusetts 02266-8602. Orders by  mail are considered received  after
payment  by check is converted  by the transfer agent's  bank, State Street Bank
and Trust Company, into federal funds.  This is generally the next business  day
after State Street Bank receives the check.

                                       7

MINIMUM INVESTMENT REQUIRED

The  minimum initial investment in Shares is $25,000. However, an account may be
opened with a smaller amount as long as the $25,000 minimum is reached within 90
days. An  institutional  investor's minimum  investment  will be  calculated  by
combining all accounts it maintains with the Trust. Accounts established through
a non-affiliated bank or broker may be subject to a smaller minimum investment.

WHAT SHARES COST

Shares  are sold  at their  net asset  value next  determined after  an order is
received. There is no sales charge imposed by the Trust. Investors who  purchase
Shares  through a  non-affiliated bank  or broker  may be  charged an additional
service fee by that bank or broker.

The net asset value  is determined at 4:00  p.m. (Eastern time), Monday  through
Friday,  except on  (i) days on  which there  are not sufficient  changes in the
value of the Trust's portfolio securities such that its net asset value might be
materially  affected;  (ii)  days  during  which  no  Shares  are  tendered  for
redemption  and  no  orders  to  purchase Shares  are  received;  and  (iii) the
following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

SUBACCOUNTING SERVICES

Institutions  are encouraged  to open  single master  accounts. However, certain
institutions may  wish  to use  the  transfer agent's  subaccounting  system  to
minimize their internal recordkeeping requirements. The transfer agent charges a
fee  based on the level of subaccounting services rendered. Institutions holding
Shares in a fiduciary, agency, custodial, or similar capacity may charge or pass
through subaccounting fees as part of or  in addition to normal trust or  agency
account fees. They may also charge fees for other services provided which may be
related  to the ownership of Shares.  This prospectus should, therefore, be read
together with any agreement between the customer and the institution with regard
to the  services  provided,  the  fees  charged  for  those  services,  and  any
restrictions and limitations imposed.

CERTIFICATES AND CONFIRMATIONS

As  transfer agent for  the Trust, Federated Services  Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Trust.

Detailed  confirmations  of  each  purchase  or  redemption  are  sent  to  each
shareholder.  Monthly confirmations are sent to report dividends paid during the
month.

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are declared just prior
to determining  net  asset value.  If  an order  for  Shares is  placed  on  the
preceding  business day, Shares purchased by wire begin earning dividends on the
business day wire payment  is received by  State Street Bank.  If the order  for
Shares  and payment by wire  are received on the  same day, Shares begin earning
dividends on the  next business  day. Shares  purchased by  check begin  earning
dividends on the business day after the check is converted by the transfer agent
into federal funds. Dividends are automatically

                                       8

reinvested  on  payment  dates in  additional  Shares unless  cash  payments are
requested by contacting the Trust.

CAPITAL GAINS

Capital gains realized by the Trust, if  any, will be distributed at least  once
every 12 months.

REDEEMING INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------

The  Trust redeems  Shares at  their net asset  value next  determined after the
Trust receives the redemption request. Redemptions will be made on days on which
the Trust computes its net asset value. Redemption requests must be received  in
proper form and can be made by telephone request or by written request.

TELEPHONE REDEMPTION

Shareholders  may redeem their Shares by  telephoning the Trust before 4:00 p.m.
(Eastern time). Telephone redemption instructions may be recorded. All  proceeds
will  normally be wire transferred  the following business day,  but in no event
more than seven days, to the shareholder's account at a domestic commercial bank
that is a member of the Federal Reserve  System. If at any time the Trust  shall
determine  it  necessary  to  terminate or  modify  this  method  of redemption,
shareholders would be promptly notified.

An authorization form  permitting the  Trust to accept  telephone requests  must
first  be completed.  Authorization forms  and information  on this  service are
available from Federated Securities Corp.

In the event of drastic economic or market changes, a shareholder may experience
difficulty in  redeeming by  telephone. If  such a  case should  occur,  another
method  of  redemption,  such  as written  requests,  should  be  considered. If
reasonable procedures are not followed by the Trust, it may be liable for losses
due to unauthorized or fraudulent telephone instructions.

WRITTEN REQUESTS

Shares may also be redeemed by sending a written request to the Trust. Call  the
Trust for specific instructions before redeeming by letter. The shareholder will
be  asked to provide in the request his name, the Trust name and class of shares
name, his account  number, and the  share or dollar  amount requested. If  share
certificates have been issued, they must be properly endorsed and should be sent
by  registered  or certified  mail to  Federated  Services Company,  500 Victory
Road-2nd Floor, Quincy, Massachusetts, 02171 with the written request.

SIGNATURES.   Shareholders  requesting  a  redemption  of  $50,000  or  more,  a
redemption of any amount to be sent to an address other than that on record with
the  Trust, or a redemption payable other than to the shareholder of record must
have signatures on written redemption requests guaranteed by:

    - a trust company or commercial bank whose deposits are insured by the  Bank
      Insurance  Fund  ("BIF"), which  is  administered by  the  Federal Deposit
      Insurance Corporation ("FDIC");

    - a member of  the New  York, American,  Boston, Midwest,  or Pacific  Stock
      Exchange;

                                       9

    - a  savings bank or savings and loan association whose deposits are insured
      by the Savings Association Insurance Fund ("SAIF"), which is  administered
      by the FDIC; or

    - any  other "eligible guarantor institution,"  as defined in the Securities
      Exchange Act of 1934.

The Trust does not accept signatures guaranteed by a notary public.

The Trust and its transfer agent have adopted standards for accepting  signature
guarantees  from the above  institutions. The Trust  may elect in  the future to
limit eligible  signature  guarantors to  institutions  that are  members  of  a
signature  guarantee program. The Trust and its transfer agent reserve the right
to amend these standards at any time without notice.

RECEIVING PAYMENT.   Normally, a  check for the  proceeds is  mailed within  one
business  day, but in no  event more than seven days,  after receipt of a proper
written redemption request.

ACCOUNTS WITH LOW BALANCES

Due to the high cost  of maintaining accounts with  low balances, the Trust  may
redeem  Shares in  any account and  pay the  proceeds to the  shareholder if the
account  balance  falls  below  a  required  minimum  value  of  $25,000.   This
requirement  does not apply, however, if the balance falls below $25,000 because
of changes in the Trust's net asset value.

Before Shares are redeemed to close  an account, the shareholder is notified  in
writing  and allowed 30 days  to purchase additional Shares  to meet the minimum
requirement.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections  and
other  matters submitted to shareholders for vote.  All shares of all classes of
each portfolio in  the Trust  have equal voting  rights except  that in  matters
affecting only a particular portfolio or class, only shares of that portfolio or
class  are entitled to vote. As a Massachusetts business trust, the Trust is not
required to  hold  annual shareholder  meetings.  Shareholder approval  will  be
sought only for certain changes in the Trust's operation and for the election of
Trustees under certain circumstances.

Trustees may be removed by the Trustees or by shareholders at a special meeting.
A  special meeting of the  shareholders for this purpose  shall be called by the
Trustees upon the  written request of  shareholders owning at  least 10% of  the
outstanding shares of the Trust entitled to vote.

MASSACHUSETTS PARTNERSHIP LAW

Under  certain  circumstances, shareholders  may  be held  personally  liable as
partners under Massachusetts law  for obligations of the  Trust. To protect  the
shareholders   of  the  Trust,   the  Trust  has   filed  legal  documents  with
Massachusetts that expressly disclaim the liability of its shareholders for such
acts or  obligations  of the  Trust.  These  documents require  notice  of  this
disclaimer  to be  given in each  agreement, obligation, or  instrument that the
Trust or its Trustees enter into or sign on behalf of the Trust.

                                       10

In the unlikely event  a shareholder is held  personally liable for the  Trust's
obligations,  the Trust is required to use its property to protect or compensate
the shareholder. On request, the  Trust will defend any  claim made and pay  any
judgment  against  a  shareholder  for  any  act  or  obligation  of  the Trust.
Therefore, financial loss resulting from  liability as a shareholder will  occur
only  if the Trust itself cannot  meet its obligations to indemnify shareholders
and pay judgments against them from its assets.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Trust will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code applicable to regulated investment companies and to
receive the special tax treatment afforded to such companies.

Unless otherwise exempt, shareholders are required to pay federal income tax  on
any  dividends and other distributions  received. This applies whether dividends
and distributions are received in cash or as additional shares.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston & Donnelly, counsel to the Trust:

    - the Trust is not  subject to Pennsylvania  corporate or personal  property
      taxes; and

    - Trust  shares  may  be  subject  to  personal  property  taxes  imposed by
      counties, municipalities,  and school  districts  in Pennsylvania  to  the
      extent that the portfolio securities in the Trust would be subject to such
      taxes if owned directly by residents of those jurisdictions.

Shareholders are urged to consult their own tax advisers regarding the status of
their accounts under state and local tax laws.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Trust advertises its total return and yield for Shares.

Total  return represents  the change,  over a specified  period of  time, in the
value of an investment in Shares of  the Trust after reinvesting all income  and
capital  gain distributions.  It is  calculated by  dividing that  change by the
initial investment and is expressed as a percentage.

The yield of Shares of  the Trust is calculated  by dividing the net  investment
income  per share (as defined by  the Securities and Exchange Commission) earned
by Shares over a thirty-day  period by the maximum  offering price per share  of
Shares  on the  last day  of the  period. This  number is  then annualized using
semi-annual compounding. The yield does not necessarily reflect income  actually
earned  by Shares and,  therefore, may not  correlate to the  dividends or other
distributions paid to shareholders.

The Trust  is sold  without  any sales  charge  or other  similar  non-recurring
charges.

                                       11

Total  return and yield  will be calculated  separately for Institutional Shares
and Institutional  Service  Shares.  Because Institutional  Service  Shares  are
subject  to 12b-1 fees, the total return and yield for Institutional Shares, for
the same period, will exceed that of Institutional Service Shares.

From time  to  time, the  Trust  may  advertise its  performance  using  certain
financial publications and/or compare its performance to certain indices.

OTHER CLASSES OF SHARES
- --------------------------------------------------------------------------------

The  Trust  also offers  another class  of  shares called  Institutional Service
Shares. Institutional Service Shares  are sold at net  asset value primarily  to
retail  and private banking customers of  financial institutions and are subject
to a minimum initial investment of $25,000.

Institutional Shares and Institutional Service Shares are subject to certain  of
the same expenses; however, Institutional Service Shares are distributed under a
12b-1  Plan adopted by  the Trust. This, plus  other expense differences between
Institutional  Shares  and   Institutional  Service  Shares,   may  affect   the
performance of each class.

To  obtain more information  and a prospectus  for Institutional Service Shares,
investors may call 1-800-235-4669.

government  obligations  are   generally  valued   at  the   mean  between   the
over-the-counter  bid and  asked prices as  furnished by  an independent pricing
service.

REPURCHASE AGREEMENTS--It is the  policy of the Trust  to require the  custodian
bank  to take possession, to have legally segregated in the Federal Reserve Book
Entry System,  or to  have segregated  within the  custodian bank's  vault,  all
securities  held as collateral  in support of  repurchase agreement investments.
Additionally, procedures have  been established by  the Trust to  monitor, on  a
daily  basis,  the  market  value  of  each  repurchase  agreement's  underlying
collateral to ensure that the value of collateral at least equals the  principal
amount of the repurchase agreement, including accrued interest.

The  Trust  will only  enter  into repurchase  agreements  with banks  and other
recognized financial institutions, such as  broker/dealers, which are deemed  by
the Trust's adviser to be creditworthy pursuant to the guidelines established by
the  Board  of Trustees  (the "Trustees").  Risks may  arise from  the potential
inability of  counterparties to  honor the  terms of  the repurchase  agreement.
Accordingly,  the Trust could receive less than the repurchase price on the sale
of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses  are
accrued  daily.  Bond  premium and  discount,  if applicable,  are  amortized as
required by the Internal Revenue Code, as amended (the "Code"). Distributions to
shareholders are recorded on the ex-dividend date.

(FORMERLY FEDERATED SHORT-INTERMEDIATE GOVERNMENT TRUST)
- --------------------------------------------------------------------------------

FEDERAL TAXES--It is  the Trust's policy  to comply with  the provisions of  the
Code   applicable  to  regulated  investment  companies  and  to  distribute  to
shareholders each year substantially all of its taxable income. Accordingly,  no
provisions for federal tax are necessary.

At  February 28, 1995,  the Trust for  federal tax purposes,  had a capital loss
carryforward of  $121,361,005,  which will  reduce  the Trust's  taxable  income
arising  from future  net realized  gain on investments,  if any,  to the extent
permitted by  the Code,  and thus  will reduce  the amount  of distributions  to
shareholders  which would  otherwise be  necessary to  relieve the  Trust of any
liability for  federal  tax.  Additionally, net  capital  losses  of  $9,639,860
attributable  to  security  transactions  incurred after  October  31,  1994 are
treated as arising on March 1, the first day of the Trust's next taxable year.

    Pursuant to  the  Code,  such  capital loss  carryforwards  will  expire  as
follows:

</TABLE>

WHEN-ISSUED   AND  DELAYED  DELIVERY  TRANSACTIONS--The   Trust  may  engage  in
when-issued or  delayed delivery  transactions.  The Trust  records  when-issued
securities  on  the  trade  date  and  maintains  security  positions  such that
sufficient liquid assets will  be available to make  payment for the  securities
purchased.  Securities purchased on a when-issued  or delayed delivery basis are
marked to market daily and begin earning interest on the settlement date.

OTHER--Investment transactions are accounted for on the trade date.

(3) SHARES OF BENEFICIAL INTEREST

The Declaration of Trust  permits the Trustees to  issue an unlimited number  of
full  and fractional shares of beneficial  interest (without par value) for each
class of shares.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
- ---------------------------------------------------------

To the Trustees and Shareholders of
FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS:
(formerly Federated Short-Intermediate Government Trust)

We  have  audited  the  accompanying  statement  of  assets  and  liabilities of
Federated U.S. Government Securities Fund:  1-3 Years (formerly Federated  Short
Intermediate  Government Trust)  including the  portfolio of  investments, as of
February 28, 1995,  and the related  statement of operations  for the year  then
ended,  the statement of changes in net assets  for each of the two years in the
period then ended, and the financial  highlights (see page 2 of the  prospectus)
for  each  of  the periods  indicated  therein. These  financial  statements and
financial highlights  are  the responsibility  of  the Trust's  management.  Our
responsibility  is  to  express an  opinion  on these  financial  statements and
financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance  about  whether  the  financial  statements  and  financial
highlights  are free of material misstatement. An audit includes examining, on a
test basis, evidence  supporting the  amounts and disclosures  in the  financial
statements.  Our  procedures included  confirmation  of securities  owned  as of
February 28, 1995 by correspondence with  the custodian. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.

In  our opinion, the  financial statements and  financial highlights referred to
above present  fairly,  in all  material  respects, the  financial  position  of
Federated  U.S. Government Securities Fund: 1-3  Years at February 28, 1995, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the periods indicated therein, in conformity with generally accepted
accounting principles.

(1)   The Management Fee   has   been reduced to reflect the voluntary waiver of
     a portion of the management fee.  The adviser can terminate this  voluntary
     waiver  at any time at  its sole discretion. The  maximum management fee is
     0.40%.
(2)  The maximum 12b-1 Fee is 0.25%.
(3)  The maximum Shareholder Services Fee is 0.25%.
(4)  The  Total Institutional  Service Shares  Operating Expenses  in the  table
     above are based on expenses expected during the fiscal year ending February
     29,  1996. The Total  Institutional Service Shares  Operating Expenses were
     0.79% for the  fiscal year  ended February 28,  1995, and  would have  been
     1.04% absent the voluntary waivers of a portion of the management fee and a
     portion of the 12b-1 fee.

    The  purpose of  this table  is to assist  an investor  in understanding the
various costs and expenses that a shareholder of Institutional Service Shares of
the  Trust  will  bear,  either  directly  or  indirectly.  For  more   complete
descriptions  of the various costs and expenses, see "Investing in Institutional
Service Shares" and  "Trust Information." Wire-transferred  redemptions of  less
than $5,000 may be subject to additional fees.

GENERAL INFORMATION
- --------------------------------------------------------------------------------

The Trust was established as a Massachusetts business trust under a  Declaration
of  Trust dated January 3,  1984. The Declaration of  Trust permits the Trust to
offer separate series of shares of beneficial interest representing interests in
separate portfolios  of securities.  The  shares in  any  one portfolio  may  be
offered  in separate classes.  As of the  date of this  prospectus, the Board of
Trustees (the "Trustees") have established two  classes of shares of the  Trust,
known  as Institutional Service Shares and Institutional Shares. This prospectus
relates only to Institutional Service Shares.

Institutional Service Shares  ("Shares") are designed  primarily for retail  and
private  banking customers  of financial institutions  as a  convenient means of
accumulating an interest in a  professionally managed, diversified portfolio  of
U.S.  government  securities. A  minimum initial  investment  of $25,000  over a
90-day period is required.

Shares are currently sold and redeemed at net asset value without a sales charge
imposed by the Trust.

INVESTMENT INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE

The investment  objective of  the Trust  is current  income. While  there is  no
assurance  that the Trust will achieve its investment objective, it endeavors to
do so by following the investment policies described in this prospectus.  Unless
otherwise  noted,  the investment  objective  and the  policies  and limitations
described below cannot be changed without approval of shareholders.

INVESTMENT POLICIES

The Trust  pursues its  investment  objective by  investing in  U.S.  government
securities  with remaining  maturities of 3  1/2 years  or less. As  a matter of
investment practice which can be changed without shareholder approval, the Trust
will maintain a dollar-weighted average portfolio maturity of 1 to 3 years.

ACCEPTABLE INVESTMENTS.   The  U.S.  government securities  in which  the  Trust
invests are either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities are limited to:

    - direct  obligations of  the U.S.  Treasury, such  as U.S.  Treasury bills,
      notes, and bonds; and

    - notes,  bonds,  and  discount  notes   of  U.S.  government  agencies   or
      instrumentalities, such as the: Farm Credit System, including the National
      Bank  for  Cooperatives, Farm  Credit Banks,  and Banks  for Cooperatives;
      Farmers Home Administration;  Federal Home Loan  Banks; Federal Home  Loan
      Mortgage  Corporation; Federal  National Mortgage  Association; Government
      National  Mortgage  Association;   Student  Loan  Marketing   Association;
      Tennessee  Valley  Authority;  Export-Import Bank  of  the  United States;
      Commodity Credit Corporation; Federal Financing Bank; and National  Credit
      Union Administration.

                                       3

Some  obligations issued or  guaranteed by agencies  or instrumentalities of the
U.S. government, such as Government National Mortgage Association  participation
certificates,  are backed by the full faith  and credit of the U.S. Treasury. No
assurances can be given that the U.S. government will provide financial  support
to  other agencies or instrumentalities, since it is not obligated to do so. The
instrumentalities are supported by:

    - the issuer's  right to  borrow an  amount limited  to a  specific line  of
      credit from the U.S. Treasury;

    - discretionary  authority  of  the  U.S.  government  to  purchase  certain
      obligations of an agency or instrumentality; or

    - the credit of the agency or instrumentality.

The prices of fixed  income securities fluctuate inversely  to the direction  of
interest rates.

    REPURCHASE  AGREEMENTS.   Repurchase  agreements  are arrangements  in which
    banks, broker/  dealers, and  other recognized  financial institutions  sell
    U.S. government securities or other securities to the Trust and agree at the
    time of sale to repurchase them at a mutually agreed upon time and price. To
    the  extent that the original seller does not repurchase the securities from
    the Trust, the  Trust could receive  less than the  repurchase price on  any
    sale of such securities.

    As  a matter of investment practice which can be changed without shareholder
    approval, the Trust  will not  invest more  than 15%  of its  net assets  in
    securities which are illiquid, including repurchase agreements providing for
    settlement in more than seven days after notice.

WHEN-ISSUED  AND  DELAYED  DELIVERY TRANSACTIONS.    As a  matter  of investment
practice which  can  be changed  without  shareholder approval,  the  Trust  may
purchase   securities  on  a  when-issued   or  delayed  delivery  basis.  These
transactions are  arrangements  in which  the  Trust purchases  securities  with
payment  and  delivery scheduled  for  a future  time.  The seller's  failure to
complete these  transactions  may cause  the  Trust to  miss  a price  or  yield
considered  to be advantageous.  Settlement dates may  be a month  or more after
entering into  these  transactions, and  the  market values  of  the  securities
purchased  may vary  from the  purchase prices.  Accordingly, the  Trust may pay
more/less than the market value of the securities on the settlement date.

The Trust may dispose of a commitment  prior to settlement if the adviser  deems
it  appropriate to do  so. In addition,  the Trust may  enter in transactions to
sell its purchase  commitments to  third parties  at current  market values  and
simultaneously acquire other commitments to purchase similar securities at later
dates.  The Trust may realize short-term profits or losses upon the sale of such
commitments.

PORTFOLIO TRANSACTIONS.  The Trust conducts portfolio transactions to accomplish
its investment objective as interest rates change, to invest new money  obtained
from  selling its shares, and to meet redemption requests. The Trust may dispose
of portfolio securities at  any time if it  appears that selling the  securities
will help the Trust achieve its investment objective.

                                       4

INVESTMENT LIMITATIONS

The  Trust  will  not  borrow  money  or  pledge  assets  except,  under certain
circumstances, the Trust may borrow  up to one-third of  the value of its  total
assets  and  pledge up  to  10% of  the  value of  those  assets to  secure such
borrowings.

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The  Trust is managed by a  Board of Trustees. The  Trustees
are responsible for managing the Trust's business affairs and for exercising all
the  Trust's powers  except those reserved  for the  shareholders. The Executive
Committee of the Board of Trustees handles the Board's responsibilities  between
meetings of the Board.

INVESTMENT  ADVISER.  Investment  decisions for the Trust  are made by Federated
Management,  the  Trust's  investment  adviser,  subject  to  direction  by  the
Trustees.  The adviser continually conducts  investment research and supervision
for the  Trust  and  is  responsible  for the  purchase  or  sale  of  portfolio
instruments, for which it receives an annual fee from the Trust.

    ADVISORY  FEES.  The Trust's adviser  receives an annual investment advisory
    fee equal to .40 of 1% of the Trust's average daily net assets. The  adviser
    has  also undertaken to reimburse the Trust for operating expenses in excess
    of  limitations  established  by  certain  states.  This  does  not  include
    reimbursement  to the Trust of any expenses incurred by shareholders who use
    the transfer agent's subaccounting facilities.

    ADVISER'S BACKGROUND.    Federated  Management, a  Delaware  business  trust
    organized  on April 11,  1989, is a registered  investment adviser under the
    Investment Advisers Act of 1940. It is a subsidiary of Federated  Investors.
    All  of the Class  A (voting) shares  of Federated Investors  are owned by a
    trust, the trustees of  which are John F.  Donahue, Chairman and Trustee  of
    Federated   Investors,  Mr.  Donahue's  wife,  and  Mr.  Donahue's  son,  J.
    Christopher Donahue, who is President and Trustee of Federated Investors.

    Federated Management and other subsidiaries of Federated Investors serve  as
    investment  advisers  to  a  number  of  investment  companies  and  private
    accounts. Certain other subsidiaries also provide administrative services to
    a  number  of  investment  companies.  Total  assets  under  management   or
    administration  by these and  other subsidiaries of  Federated Investors are
    approximately $70 billion. Federated Investors, which was founded in 1956 as
    Federated Investors, Inc., develops and  manages mutual funds primarily  for
    the  financial industry.  Federated Investors'  track record  of competitive
    performance and  its disciplined,  risk averse  investment philosophy  serve
    approximately  3,500  client  institutions  nationwide.  Through  these same
    client institutions, individual shareholders also  have access to this  same
    level of investment expertise.

    Joseph  M. Balestrino has been the Trust's co-portfolio manager since March,
    1995. Mr. Balestrino  joined Federated  Investors in  1986 and  has been  an
    Assistant  Vice President of the Trust's  investment adviser since 1991. Mr.
    Balestrino   served   as   an   Investment   Analyst   of   the   investment

                                       5

    adviser  from 1989 until 1991, and from  1986 until 1989 he acted as Project
    Manager in the Product Development Department. Mr. Balestrino is a Chartered
    Financial Analyst and received his M.A. in Urban and Regional Planning  from
    the University of Pittsburgh.

    Susan  M. Nason  has been the  Trust's co-portfolio  manager since September
    1991. Ms.  Nason joined  Federated Investors  in 1987  and has  been a  Vice
    President  of the Trust's investment adviser since 1993. Ms. Nason served as
    an Assistant Vice President of the investment adviser from 1990 until  1992,
    and  from 1987 until 1990 she acted as an investment analyst. Ms. Nason is a
    Chartered Financial Analyst and received her M.B.A. in Finance from Carnegie
    Mellon University.

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

Federated Securities Corp. is the principal distributor for the Shares. It is  a
Pennsylvania  corporation organized on  November 14, 1969,  and is the principal
distributor for a number of investment companies. Federated Securities Corp.  is
a subsidiary of Federated Investors.

DISTRIBUTION  AND SHAREHOLDER SERVICES PLANS.  Under a distribution plan adopted
in accordance with Investment Company Act Rule 12b-1 (the "Distribution  Plan"),
the  Trust may pay to  the distributor an amount, computed  at an annual rate of
0.25 of 1% of  the average daily net  asset value of the  Trust, to finance  any
activity  which is principally intended to result  in the sale of Shares subject
to the Distribution Plan. The distributor may select financial institutions such
as banks, fiduciaries,  custodians for  public funds,  investment advisers,  and
broker/dealers  to provide sales support services as agents for their clients or
customers.

The Distribution Plan is a compensation-type  plan. As such, the Trust makes  no
payments to the distributor except as described above. Therefore, the Trust does
not pay for unreimbursed expenses of the distributor, including amounts expended
by  the distributor in excess of amounts received by it from the Trust interest,
carrying or other financing charges in connection with excess amounts  expended,
or  the distributor's overhead expenses. However, the distributor may be able to
recover such amount or may earn a profit from future payments made by the  Trust
under the Distribution Plan.

In  addition, the Trust  has adopted a Shareholder  Services Plan (the "Services
Plan") under which it may  make payments up to 0.25  of 1% of the average  daily
net   asset  value  of  the  Trust  to  obtain  certain  personal  services  for
shareholders  and  the   maintenance  of   shareholder  accounts   ("shareholder
services").  The Trust  has entered into  a Shareholder  Services Agreement with
Federated Shareholder Services, a subsidiary of Federated Investors, under which
Federated Shareholder Services will either perform shareholder services directly
or will select financial institutions to perform shareholder services. Financial
institutions will  receive fees  based upon  shares owned  by their  clients  or
customers. The schedules of such fees and the basis upon which such fees will be
paid will be determined from time to time by the Trust and Federated Shareholder
Services.

The  Glass-Steagall Act prohibits a depository institution (such as a commercial
bank or a savings and loan association) from being an underwriter or distributor
of most securities. In  the event the Glass-Steagall  Act is deemed to  prohibit
depository  institutions from acting in  the administrative capacities described
above or should Congress relax current restrictions on depository  institutions,
the Board of Trustees will consider appropriate changes in the services.

                                       6

State securities laws governing the ability of depository institutions to act as
underwriters or distributors of securities may differ from interpretations given
to  the Glass-Steagall Act and, therefore,  banks and financial institutions may
be required to register as dealers pursuant to state law.

ADMINISTRATION OF THE TRUST

ADMINISTRATIVE SERVICES.   Federated  Administrative Services,  a subsidiary  of
Federated  Investors, provides administrative  personnel and services (including
certain legal and financial reporting services) necessary to operate the  Trust.
Federated Administrative Services provides these at an annual rate which relates
to  the average aggregate daily net assets  of all funds advised by subsidiaries
of Federated Investors ("Federated Funds") as specified below.

</TABLE>

The administrative  fee  received during  any  fiscal  year shall  be  at  least
$125,000  per  portfolio  and  $30,000  per  each  additional  class  of shares.
Federated Administrative Services may choose  voluntarily to waive a portion  of
its fee.

CUSTODIAN.   State Street Bank and  Trust Company ("State Street Bank"), Boston,
Massachusetts, is custodian for the securities and cash of the Trust.

TRANSFER AGENT  AND  DIVIDEND DISBURSING  AGENT.   Federated  Services  Company,
Pittsburgh,  Pennsylvania, is  transfer agent  for the  shares of  the Trust and
dividend disbursing agent for the Trust.

INDEPENDENT AUDITORS.  The independent auditors for the Trust are Ernst &  Young
LLP, Pittsburgh, Pennsylvania 15219.

NET ASSET VALUE
- --------------------------------------------------------------------------------

The Trust's net asset value per share fluctuates. The net asset value for Shares
is  determined by adding the  interest of the Shares in  the market value of all
securities and other assets of the Trust, subtracting the interest of the Shares
in the liabilities of the Trust  and those attributable to Shares, and  dividing
the remainder by the total number of Shares outstanding. The net asset value for
Institutional  Shares may exceed that of Institutional Service Shares due to the
variance in daily net income realized by each class. Such variance will  reflect
only  accrued net  income to  which the shareholders  of a  particular class are
entitled.

INVESTING IN INSTITUTIONAL SERVICE SHARES

BY WIRE.  To purchase Shares by Federal Reserve wire, call the Trust before 4:00
p.m. (Eastern  time)  to  place  an order.  The  order  is  considered  received
immediately.  Payment by  federal wire funds  must be received  before 3:00 p.m.
(Eastern time)  on the  next business  day following  the order.  Federal  funds
should  be wired as  follows: Federated Services Company,  c/o State Street Bank
and Trust Company,  Boston, Massachusetts; Attention:  EDGEWIRE; For Credit  to:
Federated  U.S.  Government  Securities Fund:  1-3  Years--Institutional Service
Shares; Trust Number (this number  can be found on  the account statement or  by
contacting the Trust); Group Number or Wire Order Number; Nominee or Institution
Name; and ABA Number 011000028.

BY  MAIL.  To  purchase Shares by mail,  send a check  made payable to Federated
U.S. Government  Securities Fund:  1-3  Years--Institutional Service  Shares  to
Federated  Services Company, c/o  State Street Bank and  Trust Company, P.O. Box
8602, Boston, Massachusetts 02266-8602. Orders  by mail are considered  received
after  payment by check is converted by  the transfer agent's bank, State Street
Bank and Trust Company, into federal funds. This is generally the next  business
day after State Street Bank receives the check.

MINIMUM INVESTMENT REQUIRED

The  minimum initial investment in Shares is $25,000. However, an account may be
opened with a smaller amount as long as the $25,000 minimum is reached within 90
days. An  institutional  investor's minimum  investment  will be  calculated  by
combining all accounts it maintains with the Trust. Accounts established through
a non-affiliated bank or broker may be subject to a smaller minimum investment.

WHAT SHARES COST

Shares  are sold  at their  net asset  value next  determined after  an order is
received. There is no sales charge imposed by the Trust. Investors who  purchase
Shares  through a  non-affiliated bank  or broker  may be  charged an additional
service fee by that bank or broker.

The net asset value  is determined at 4:00  p.m. (Eastern time), Monday  through
Friday,  except on  (i) days on  which there  are not sufficient  changes in the
value of the Trust's portfolio securities such that its net asset value might be
materially  affected;  (ii)  days  during  which  no  Shares  are  tendered  for
redemption  and  no  orders  to  purchase Shares  are  received;  and  (iii) the
following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

SUBACCOUNTING SERVICES

Institutions  are encouraged  to open  single master  accounts. However, certain
institutions may  wish  to use  the  transfer agent's  subaccounting  system  to
minimize their internal recordkeeping requirements. The transfer agent charges a
fee  based on the level of subaccounting services rendered. Institutions holding
Shares in a fiduciary, agency, custodial, or similar capacity may charge or pass
through subaccounting fees as part of or  in addition to normal trust or  agency
account fees. They may also charge

                                       8

fees  for  other services  provided which  may  be related  to the  ownership of
Shares. This prospectus should, therefore,  be read together with any  agreement
between  the customer and the institution  with regard to the services provided,
the fees  charged  for those  services,  and any  restrictions  and  limitations
imposed.

CERTIFICATES AND CONFIRMATIONS

As  transfer agent for  the Trust, Federated Services  Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Trust.

Detailed  confirmations  of  each  purchase  or  redemption  are  sent  to  each
shareholder.  Monthly confirmations are sent to report dividends paid during the
month.

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are declared just prior
to determining  net  asset value.  If  an order  for  Shares is  placed  on  the
preceding  business day, Shares purchased by wire begin earning dividends on the
business day wire payment  is received by  State Street Bank.  If the order  for
Shares  and payment by wire  are received on the  same day, Shares begin earning
dividends on the  next business  day. Shares  purchased by  check begin  earning
dividends on the business day after the check is converted by the transfer agent
into  federal funds. Dividends are automatically  reinvested on payment dates in
additional Shares unless cash payments are requested by contacting the Trust.

CAPITAL GAINS

Capital gains realized by the Trust, if  any, will be distributed at least  once
every 12 months.

REDEEMING INSTITUTIONAL SERVICE SHARES
- --------------------------------------------------------------------------------

The  Trust redeems  Shares at  their net asset  value next  determined after the
Trust receives the redemption request. Redemptions will be made on days on which
the Trust computes its net asset value. Redemption requests must be received  in
proper form and can be made by telephone request or by written request.

TELEPHONE REDEMPTION

Shareholders  may redeem their Shares by  telephoning the Trust before 4:00 p.m.
(Eastern time). Telephone redemption instructions may be recorded. All  proceeds
will  normally be wire transferred  the following business day,  but in no event
more than seven days, to the shareholder's account at a domestic commercial bank
that is a member of the Federal Reserve  System. If at any time the Trust  shall
determine  it  necessary  to  terminate or  modify  this  method  of redemption,
shareholders would be promptly notified.

An authorization form  permitting the  Trust to accept  telephone requests  must
first  be completed.  Authorization forms  and information  on this  service are
available from Federated Securities Corp.

In the event of drastic economic or market changes, a shareholder may experience
difficulty in  redeeming by  telephone. If  such a  case should  occur,  another
method of redemption, such as written

                                       9

requests, should be considered. If reasonable procedures are not followed by the
Trust,  it may be liable for losses  due to unauthorized or fraudulent telephone
instructions.

WRITTEN REQUESTS

Shares may also be redeemed by sending a written request to the Trust. Call  the
Trust for specific instructions before redeeming by letter. The shareholder will
be  asked to provide in the request his name, the Trust name and class of shares
name, his account  number, and the  share or dollar  amount requested. If  share
certificates have been issued, they must be properly endorsed and should be sent
by  registered  or certified  mail to  Federated  Services Company,  500 Victory
Road-2nd Floor, Quincy, Massachusetts, 02171 with the written request.

SIGNATURES.   Shareholders  requesting  a  redemption  of  $50,000  or  more,  a
redemption of any amount to be sent to an address other than that on record with
the  Trust, or a redemption payable other than to the shareholder of record must
have signatures on written redemption requests guaranteed by:

    - a trust company or commercial bank whose deposits are insured by the  Bank
      Insurance  Fund  ("BIF"), which  is  administered by  the  Federal Deposit
      Insurance Corporation ("FDIC");

    - a member of  the New  York, American,  Boston, Midwest,  or Pacific  Stock
      Exchange;

    - a  savings bank or savings and loan association whose deposits are insured
      by the Savings Association Insurance Fund ("SAIF"), which is  administered
      by the FDIC; or

    - any  other "eligible guarantor institution,"  as defined in the Securities
      Exchange Act of 1934.

The Trust does not accept signatures guaranteed by a notary public.

The Trust and its transfer agent have adopted standards for accepting  signature
guarantees  from the above  institutions. The Trust  may elect in  the future to
limit eligible  signature  guarantors to  institutions  that are  members  of  a
signature  guarantee program. The Trust and its transfer agent reserve the right
to amend these standards at any time without notice.

RECEIVING PAYMENT.   Normally, a  check for the  proceeds is  mailed within  one
business  day, but in no  event more than seven days,  after receipt of a proper
written redemption request.

ACCOUNTS WITH LOW BALANCES

Due to the high cost  of maintaining accounts with  low balances, the Trust  may
redeem  Shares in  any account and  pay the  proceeds to the  shareholder if the
account  balance  falls  below  a  required  minimum  value  of  $25,000.   This
requirement  does not apply, however, if the balance falls below $25,000 because
of changes in the Trust's net asset value.

Before Shares are redeemed to close  an account, the shareholder is notified  in
writing  and allowed 30 days  to purchase additional Shares  to meet the minimum
requirement.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections  and
other  matters submitted to shareholders for vote.  All shares of all classes of
each portfolio in  the Trust  have equal voting  rights except  that in  matters
affecting only a particular portfolio or class, only shares of that portfolio or
class  are entitled to vote. As a Massachusetts business trust, the Trust is not
required to  hold  annual shareholder  meetings.  Shareholder approval  will  be
sought only for certain changes in the Trust's operation and for the election of
Trustees  under certain circumstances. As of April 7, 1995, Charles Schwab & Co.
Inc., owned 1,084,994 shares (33.48%) of voting securities of the  Institutional
Service  Shares  of the  Trust, and,  therefore, may,  for certain  purposes, be
deemed to control the Trust and be able to affect the outcome of certain matters
presented for a vote of shareholders.

Trustees may be removed by the Trustees or by shareholders at a special meeting.
A special meeting of the  shareholders for this purpose  shall be called by  the
Trustees  upon the written  request of shareholders  owning at least  10% of the
outstanding shares of the Trust entitled to vote.

MASSACHUSETTS PARTNERSHIP LAW

Under certain  circumstances,  shareholders may  be  held personally  liable  as
partners  under Massachusetts law  for obligations of the  Trust. To protect the
shareholders  of  the  Trust,   the  Trust  has   filed  legal  documents   with
Massachusetts that expressly disclaim the liability of its shareholders for such
acts  or  obligations  of the  Trust.  These  documents require  notice  of this
disclaimer to be  given in each  agreement, obligation, or  instrument that  the
Trust or its Trustees enter into or sign on behalf of the Trust.

In  the unlikely event a  shareholder is held personally  liable for the Trust's
obligations, the Trust is required to use its property to protect or  compensate
the  shareholder. On request, the  Trust will defend any  claim made and pay any
judgment against  a  shareholder  for  any  act  or  obligation  of  the  Trust.
Therefore,  financial loss resulting from liability  as a shareholder will occur
only if the Trust itself cannot  meet its obligations to indemnify  shareholders
and pay judgments against them from its assets.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Trust will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code applicable to regulated investment companies and to
receive the special tax treatment afforded to such companies.

Unless  otherwise exempt, shareholders are required to pay federal income tax on
any dividends and other distributions  received. This applies whether  dividends
and distributions are received in cash or as additional shares.

                                       11

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston & Donnelly, counsel to the Trust:

    - the  Trust is not  subject to Pennsylvania  corporate or personal property
      taxes; and

    - Trust shares  may  be  subject  to  personal  property  taxes  imposed  by
      counties,  municipalities,  and school  districts  in Pennsylvania  to the
      extent that the portfolio securities in the Trust would be subject to such
      taxes if owned directly by residents of those jurisdictions.

Shareholders are urged to consult their own tax advisers regarding the status of
their accounts under state and local tax laws.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Trust advertises its total return and yield for Shares.

Total return represents  the change,  over a specified  period of  time, in  the
value  of an investment in Shares of  the Trust after reinvesting all income and
capital gain distributions.  It is  calculated by  dividing that  change by  the
initial investment and is expressed as a percentage.

The  yield of Shares of  the Trust is calculated  by dividing the net investment
income per share (as defined by  the Securities and Exchange Commission)  earned
by  Shares over a thirty-day  period by the maximum  offering price per share of
Shares on the  last day  of the  period. This  number is  then annualized  using
semi-annual  compounding. The yield does not necessarily reflect income actually
earned by Shares  and, therefore, may  not correlate to  the dividends or  other
distributions paid to shareholders.

The Trust is sold without any sales charge.

Total  return and yield will be  calculated separately for Institutional Service
Shares and  Institutional  Shares.  Because  Institutional  Service  Shares  are
subject  to 12b-1 fees, the total return and yield for Institutional Shares, for
the same period, will exceed that of Institutional Service Shares.

From time  to  time, the  Trust  may  advertise its  performance  using  certain
financial publications and/or compare its performance to certain indices.

OTHER CLASSES OF SHARES
- --------------------------------------------------------------------------------

The  Trust  also offers  another class  of  shares called  Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in a fiduciary or agency capacity and are subject  to
a minimum initial investment of $25,000.

Institutional  Service Shares and Institutional Shares are subject to certain of
the same expenses;  however, Institutional  Shares are not  distributed under  a
12b-1  Plan. This, plus other  expense differences between Institutional Service
Shares and Institutional Shares, may affect the performance of each class.

To obtain more information and a prospectus for Institutional Shares,  investors
may call 1-800-235-4669.

FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS
(FORMERLY FEDERATED SHORT-INTERMEDIATE GOVERNMENT TRUST)

NOTES TO FINANCIAL STATEMENTS
FEBRUARY 28, 1995
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Federated U.S. Government Securities Fund: 1-3 Years (the "Trust") is registered
under  the  Investment  Company  Act  of 1940,  as  amended  (the  "Act"),  as a
diversified, open-end management investment company.

The Trust provides two classes of shares: Institutional Shares and Institutional
Service Shares.

Effective April  13, 1995  the  Trust changed  its  name from  "Federated  Short
Intermediate  Government Trust"  to "Federated U.S.  Government Securities Fund:
1-3 Years".

(2) SIGNIFICANT ACCOUNTING POLICIES

The following  is  a summary  of  significant accounting  policies  consistently
followed  by  the Fund  in the  preparation of  its financial  statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS--Short-term securities with remaining maturities of  sixty
days  or less may  be stated at  amortized cost, which  approximates value. U.S.
government  obligations  are   generally  valued   at  the   mean  between   the
over-the-counter  bid and  asked prices as  furnished by  an independent pricing
service.

REPURCHASE AGREEMENTS--It is the  policy of the Trust  to require the  custodian
bank  to take possession, to have legally segregated in the Federal Reserve Book
Entry System,  or to  have segregated  within the  custodian bank's  vault,  all
securities  held as collateral  in support of  repurchase agreement investments.
Additionally, procedures have  been established by  the Trust to  monitor, on  a
daily  basis,  the  market  value  of  each  repurchase  agreement's  underlying
collateral to ensure that the value of collateral at least equals the  principal
amount of the repurchase agreement, including accrued interest.

The  Trust  will only  enter  into repurchase  agreements  with banks  and other
recognized financial institutions, such as  broker/dealers, which are deemed  by
the Trust's adviser to be creditworthy pursuant to the guidelines established by
the  Board  of Trustees  (the "Trustees").  Risks may  arise from  the potential
inability of  counterparties to  honor the  terms of  the repurchase  agreement.
Accordingly,  the Trust could receive less than the repurchase price on the sale
of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses  are
accrued  daily.  Bond  premium and  discount,  if applicable,  are  amortized as
required by the Internal Revenue Code, as amended (the "Code"). Distributions to
shareholders are recorded on the ex-dividend date.

                                       17

FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS
(FORMERLY FEDERATED SHORT-INTERMEDIATE GOVERNMENT TRUST)
- --------------------------------------------------------------------------------

FEDERAL TAXES--It is  the Trust's policy  to comply with  the provisions of  the
Code   applicable  to  regulated  investment  companies  and  to  distribute  to
shareholders each year substantially all of its taxable income. Accordingly,  no
provisions for federal tax are necessary.

At  February 28, 1995,  the Trust for  federal tax purposes,  had a capital loss
carryforward of  $121,361,005,  which will  reduce  the Trust's  taxable  income
arising  from future  net realized  gain on investments,  if any,  to the extent
permitted by  the Code,  and thus  will reduce  the amount  of distributions  to
shareholders  which would  otherwise be  necessary to  relieve the  Trust of any
liability for  federal  tax.  Additionally, net  capital  losses  of  $9,639,860
attributable  to  security  transactions  incurred after  October  31,  1994 are
treated as arising on March 1, the first day of the Trust's next taxable year.

    Pursuant to  the  Code,  such  capital loss  carryforwards  will  expire  as
follows:

     2003          (16,372,726)
</TABLE>

WHEN-ISSUED   AND  DELAYED  DELIVERY  TRANSACTIONS--The   Trust  may  engage  in
when-issued or  delayed delivery  transactions.  The Trust  records  when-issued
securities  on  the  trade  date  and  maintains  security  positions  such that
sufficient liquid assets will  be available to make  payment for the  securities
purchased.  Securities purchased on a when-issued  or delayed delivery basis are
marked to market daily and begin earning interest on the settlement date.

OTHER--Investment transactions are accounted for on the trade date.

(3) SHARES OF BENEFICIAL INTEREST

The Declaration of Trust  permits the Trustees to  issue an unlimited number  of
full  and fractional shares of beneficial  interest (without par value) for each
class of shares.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
- ---------------------------------------------------------

To the Trustees and Shareholders of
FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS:
(formerly Federated Short Intermediate Government Trust)

We  have  audited  the  accompanying  statement  of  assets  and  liabilities of
Federated U.S. Government Securities Fund:  1-3 Years (formerly Federated  Short
Intermediate  Government Trust)  including the  portfolio of  investments, as of
February 28, 1995,  and the related  statement of operations  for the year  then
ended,  the statement of changes in net assets  for each of the two years in the
period then ended, and the financial  highlights (see page 2 of the  prospectus)
for  each  of  the periods  indicated  therein. These  financial  statements and
financial highlights  are  the responsibility  of  the Trust's  management.  Our
responsibility  is  to  express an  opinion  on these  financial  statements and
financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance  about  whether  the  financial  statements  and  financial
highlights  are free of material misstatement. An audit includes examining, on a
test basis, evidence  supporting the  amounts and disclosures  in the  financial
statements.  Our  procedures included  confirmation  of securities  owned  as of
February 28, 1995, by correspondence with the custodian. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.

In  our opinion, the  financial statements and  financial highlights referred to
above present  fairly,  in all  material  respects, the  financial  position  of
Federated  U.S. Government Securities Fund:  1-3 Years (formerly Federated Short
Intermediate Government  Trust)  at  February  28,  1995,  the  results  of  its
operations  for the year then  ended, the changes in its  net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods indicated therein, in conformity with generally accepted  accounting
principles.

General Information About the Trust
Federated U.S. Government Securities Fund:  1 - 3 Years was established
as a Massachusetts business trust under a Declaration of Trust dated
January 3, 1984. On April 13, 1995 the name of the Trust was changed
from Federated Short-Intermediate Government Trust to Federated U.S.
Government Securities Fund:  1 - 3 Years.
Shares of the Trust are offered in two classes, known as Institutional
Shares and Institutional Service Shares (individually and collectively
referred to as "Shares," as the context may require). This Combined
Statement of additional information relates to the above mentioned
Shares of the Trust.
Investment Objective and Policies
The Trust's investment objective is current income.
Types of Investments
The Trust invests only in U.S. government securities with remaining
maturities of three and one-half (3 1/2) years or less. This investment
policy and the objective stated above cannot be changed without approval
of shareholders. As a matter of investment practice, which can be
changed without shareholder approval, the Trust will invest in U.S.
government securities with remaining maturities of 3 years or less.
When-Issued and Delayed Delivery Transactions
These transactions are made to secure what is considered to be an
advantageous price or yield for the Trust. No fees or other expenses,
other than normal transaction costs, are incurred. However, liquid
assets of the Trust sufficient to make payment for the securities to be
purchased are segregated on the Trust's records at the trade date. These
assets are marked to market daily and are maintained until the
transaction has been settled. The Trust does not intend to engage in
when-issued and delayed delivery transactions to an extent that would
cause the segregation of more than 20% of the total value of its assets.
Repurchase Agreements
The Trust requires its custodian to take possession of the securities
subject to repurchase agreements, and these securities are marked to
market daily. To the extent that the original seller does not repurchase
the securities from the Trust, the Trust could receive less than the
repurchase price on any sale of such securities. In the event that such
a defaulting seller filed for bankruptcy or became insolvent,
disposition of such securities by the Trust might be delayed pending
court action. The Trust believes that under the regular procedures
normally in effect for custody of the Trust's portfolio securities
subject to repurchase agreements, a court of competent jurisdiction
would rule in favor of the Trust and allow retention or disposition of
such securities. The Trust will only enter into repurchase agreements
with banks and other recognized financial institutions such as
broker/dealers which are deemed by the Trust's adviser to be
creditworthy pursuant to guidelines established by the Trustees.
Portfolio Turnover
The Trust will not attempt to set or meet a portfolio turnover rate
since any turnover would be incidental to transactions undertaken in an
attempt to achieve the Trust's investment objective. During the fiscal
years ended February 28, 1995, and February 28, 1994, the portfolio
turnover rates were 265%, and 150%, respectively.
Investment Limitations
The Trust will not change any of the investment limitations described
below without approval of shareholders.
   Selling Short and Buying on Margin
      The Trust will not sell any securities short or purchase any
      securities on margin but may obtain such short-term credits as may
      be necessary for clearance of purchases and sales of securities.
   Borrowing Money
      The Trust will not borrow money except as a temporary measure for
      extraordinary or emergency purposes and then only in amounts not
      in excess of 5% of the value of its total assets or in an amount
      up to one-third of the value of its total assets, including the
      amount borrowed, in order to meet redemption requests without
      immediately selling portfolio securities. This borrowing provision
      is not for investment leverage but solely to facilitate management
      of the portfolio by enabling the Trust to meet redemption requests
      when the liquidation of portfolio securities would be inconvenient
      or disadvantageous.
      Interest paid on borrowed funds will not be available for
      investment. The Trust will liquidate any such borrowings as soon
      as possible and may not purchase any portfolio securities while
      the borrowings are outstanding.
   Pledging Assets
      The Trust will not mortgage, pledge, or hypothecate any assets
      except to secure permitted borrowings. In those cases, it may
      mortgage, pledge, or hypothecate assets having a market value not
      exceeding 10% of the value of total assets at the time of the
      borrowing.
   Lending Cash or Securities
      The Trust will not lend any of its assets, except that it may
      purchase or hold U.S. government securities, including repurchase
      agreements, permitted by its investment objective and policies.
Except with respect to borrowing money, if a percentage limitation is
adhered to at the time of investment, a later increase or decrease in
percentage resulting from any change in value or net assets will not
result in a violation of such restriction.
The Trust did not borrow money or pledge securities in excess of 5% of
the value of its net assets during the last fiscal year and has no
present intent to do so in the coming fiscal year.
As a matter of operating policy, the Trust will not purchase any
securities while borrowings in excess of 5% of its total assets are
outstanding.

*Information is furnished for the fiscal year ended January 31, 1995.
#The aggregate compensation is provided for the Trust which is comprised
of one portfolio.
+The information is provided for the last calendar year.
Trustee Liability
The Trust's Declaration of Trust provides that the Trustees will not be
liable for errors of judgment or mistakes of fact or law. However, they
are not protected against any liability to which they would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence,
or reckless disregard of the duties involved in the conduct of their
office.
Investment Advisory Services
Adviser to the Trust
The Trust's investment adviser is Federated Management. It is a
subsidiary of Federated Investors. All of the voting securities of
Federated Investors are owned by a trust, the trustees of which are John
F. Donahue, his wife, and his son, J. Christopher Donahue.
The adviser shall not be liable to the Trust or any shareholder of the
Trust for any losses that may be sustained in the purchase, holding, or
sale of any security, or for anything done or omitted by it, except acts
or omissions involving willful misfeasance, bad faith, gross negligence,
or reckless disregard of the duties imposed upon it by its contract with
the Trust.
Advisory Fees
For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. During the
fiscal years ended February 28, 1995, 1994, and 1993, the Trust's
adviser earned $3,060,247, $3,924,302, and $4,408,159, respectively.
   State Expense Limitations
      The adviser has undertaken to comply with the expense limitations
      established by certain states for investment companies whose
      shares are registered for sale in those states. If the Trust's
      normal operating expenses (including the investment advisory fee,
      but not including brokerage commissions, interest, taxes, and
      extraordinary expenses) exceed 2 1/2% per year of the first $30
      million of average net assets, 2% per year of the next $70 million
      of average net assets, and 1 1/2% per year of the remaining
      average net assets, the adviser will reimburse the Trust for its
      expenses over the limitation.
If the Trust's monthly projected operating expenses exceed this
limitation, the investment advisory fee paid will be reduced by the
amount of the excess, subject to an annual adjustment. If the expense
limitation is exceeded, the amount to be reimbursed by the adviser will
be limited, in any single fiscal year, by the amount of the investment
advisory fee.
This arrangement is not part of the advisory contract and may be amended
or rescinded in the future.
Other Advisory Services
Federated Research Corp. receives fees from certain depository
institutions for providing consulting and portfolio advisory services
relating to each institution's program of asset management. Federated
Research Corp. may advise such clients to purchase or redeem shares of
investment companies, such as the Trust, which are managed, for a fee,
by Federated Research Corp. or other affiliates of Federated Investors,
such as the adviser, and may advise such clients to purchase and sell
securities in the direct markets. Further, Federated Research Corp., and
other affiliates of adviser, may, from time to time, provide certain
consulting services and equipment to depository institutions in order to
facilitate the purchase of shares of funds offered by Federated
Securities Corp.
Administrative Services
Federated Administrative Services, a subsidiary of Federated Investors,
provides administrative personnel and services to the Trust for a fee
described in the prospectus. Prior to March 1, 1994, Federated
Administrative Services, Inc., also a subsidiary of Federated Investors,
served as the Trust's administrator. For the fiscal year ended February
28, 1995, Federated Administrative Services earned $ 654,725. For the
fiscal years ended February 28, 1994, and 1993, Federated Administrative
Services, Inc.,  earned $629,337 and $542,061, respectively.  Dr. Henry
J. Gailliot, an officer of Federated Management, the Adviser to the
Trust,  holds approximately 20%, of the outstanding common stock and
serves as a director of Commercial Data Services, Inc., a company which
provides computer processing services to Federated Administrative
Services, Inc.
Transfer Agent and Dividend Disbursing Agent
Federated Services Company serves as transfer agent and dividend
disbursing agent for the Trust. The fee paid to the transfer agent is
based upon the size, type and number of accounts and transactions made
by shareholders.
Federated Services Company also maintains the Trust's accounting
records. The fee paid for this service is based upon the level of the
Trust's average net assets for the period plus out-of-pocket expenses.
Brokerage Transactions
When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the
order at a favorable price. In working with dealers, the adviser will
generally use those who are recognized dealers in specific portfolio
instruments, except when a better price and execution of the order can
be obtained elsewhere. The adviser makes decisions on portfolio
transactions and selects brokers and dealers subject to review by the
Board of Trustees.
The adviser may select brokers and dealers who offer brokerage and
research services. These services may be furnished directly to the Trust
or to the adviser and may include:
   o advice as to the advisability of investing in securities;
   o security analysis and reports;
   o economic studies;
   o industry studies;
   o receipt of quotations for portfolio evaluations; and
   o similar services.
The adviser and its affiliates exercise reasonable business judgment in
selecting brokers who offer brokerage and research services to execute
securities transactions. They determine in good faith that commissions
charged by such persons are reasonable in relationship to the value of
the brokerage and research services provided.
Research services provided by brokers may be used by the adviser or by
affiliates of Federated Investors in advising Federated Funds and other
accounts. To the extent that receipt of these services may supplant
services for which the adviser or its affiliates might otherwise have
paid, it would tend to reduce their expenses.
Purchasing Shares
Shares are sold at their net asset value without a sales charge on days
the New York Stock Exchange is open for business. The procedure for
purchasing Shares is explained in the respective prospectus under
"Investing in Institutional Shares" or "Investing in Institutional
Service Shares."
Distribution and Shareholder Services Plans
The Trust has adopted a Distribution Plan with respect to the
Institutional Service Shares only. In addition, the Trust has adopted a
Shareholder Services Plan with respect to both classes of shares. These
arrangements permit the payment of fees to financial institutions, the
distributor, and Federated Shareholder Services to stimulate
distribution activities and to cause services to be provided to
shareholders by a representative who has knowledge of the shareholder's
particular circumstances and goals. These activities and services may
include, but are not limited to, marketing efforts; providing office
space, equipment, telephone facilities, and various clerical,
supervisory, computer, and other personnel as necessary or beneficial to
establish and maintain shareholder accounts and records; processing
purchase and redemption transactions and automatic investments of client
account cash balances; answering routine client inquiries; and assisting
clients in changing dividend options, account designations, and
addresses.
With respect to the Institutional Service Shares class of the Trust, by
adopting the Distribution Plan, the Board of Trustees expects that the
Trust will be able to achieve a more predictable flow of cash for
investment purposes and to meet redemptions. This will facilitate more
efficient portfolio management and assist the Trust in pursuing its
investment objectives. By identifying potential investors whose needs
are served by the Trust's objectives, and properly servicing these
accounts, it may be possible to curb sharp fluctuations in rates of
redemptions and sales.
Other benefits, which may be realized under either arrangement, may
include: (1) providing personal services to shareholders; (2) investing
shareholder assets with a minimum of delay and administrative detail;
(3) enhancing shareholder recordkeeping systems; and (4) responding
promptly to shareholders' requests and inquiries concerning their
accounts.
For the fiscal period ending February 28, 1995, 1994 and 1993, payments
in the amount of $ 80,589, $96,057 and $81,184, respectively, were made
pursuant to the Distribution Plan (Institutional Service Shares only),
all of which was paid to financial institutions, of which $74,142, $0,
and $0, respectively, were waived. In addition, for this period,
payments in the amount of $74,142 were made pursuant to the Shareholder
Services Plan.
Conversion to Federal Funds
It is the Trust's policy to be as fully invested as possible so that
maximum interest may be earned. To this end, all payments from
shareholders must be in federal funds or be converted into federal
funds. State Street Bank acts as the shareholder's agent in depositing
checks and converting them to federal funds.
Determining Net Asset Value
Net asset value generally changes each day. The days on which net asset
value is calculated by the Trust are described in the respective
prospectuses. Net asset value will not be calculated on the following
holidays: New Year's Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
Determining Market Value of Securities
Market values of the Trust's portfolio securities are determined as
follows:
   o according to the mean between the over-the-counter bid and asked
      prices provided by an independent pricing service, if available,
      or at fair value as determined in good faith by the Trust's Board
      of Trustees; or
   o for short-term obligations with remaining maturities of less than
      60 days at the time of purchase, at amortized cost unless the
      Board of Trustees determines that particular circumstances of the
      security indicate otherwise.
Prices provided by independent pricing services may be determined
without relying exclusively on quoted prices. Pricing services may
consider:
   o yield;
   o quality;
   o coupon rate;
   o maturity;
   o type of issue;
   o trading characteristics; and
   o other market data.
Redeeming Shares
The Trust redeems Shares at the next computed net asset value after the
Trust receives the redemption request. Redemption procedures are
explained in the respective prospectuses under "Redeeming Institutional
Shares" and "Redeeming Institutional Service Shares." Although State
Street Bank does not charge for telephone redemptions, it reserves the
right to charge a fee for the cost of wire-transferred redemptions of
less than $5,000.
Redemption in Kind
The Trust is obligated to redeem Shares solely in cash up to $250,000 or
1% of the respective class net asset value, whichever is less, for any
one shareholder within a 90-day period.
Any redemption beyond this amount will also be in cash unless the
Trustees determine that further cash payments will have a material
adverse effect on remaining shareholders. In such a case, the Trust will
pay all or a portion of the remainder of the redemption in portfolio
instruments, valued in the same way as the Trust determines net asset
value. The portfolio instruments will be selected in a manner that the
Trustees deem fair and equitable.
Redemption in kind is not as liquid as a cash redemption. If redemption
is made in kind, shareholders receiving their securities and selling
them before their maturity could receive less than the redemption value
of their securities and could incur certain transaction costs.
Tax Status
The Trust's Tax Status
The Trust will pay no federal income tax because it expects to meet the
requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies and to receive the special tax treatment
afforded to such companies. To qualify for this treatment, the Trust
must, among other requirements:
   o derive at least 90% of its gross income from dividends, interest,
      and gains from the sale of securities;
   o derive less than 30% of its gross income from the sale of
      securities held less than three months;
   o invest in securities within certain statutory limits; and
   o distribute to its shareholders at least 90% of its net income
      earned during the year.
Shareholders' Tax Status
Shareholders are subject to federal income tax on dividends and capital
gains received as cash or additional Shares. No portion of any income
dividend paid by the Trust is eligible for the dividends received
deduction available to corporations. These dividends, and any short-term
capital gains, are taxable as ordinary income.
   Capital Gains
      Long-term capital gains distributed to shareholders will be
      treated as long-term capital gains regardless of how long
      shareholders have held Shares.
Total Return
The Trust's average annual total return for Institutional Shares for the
one-year and five-year periods ended February 28, 1995, and for the
period from March 15, 1984 (effective date of the Trust's registration
statement) to February 28, 1995 were  3.14%, 6.34%, and 7.99%,
respectively. The Trust's cumulative total return for Institutional
Service Shares for the period from June 18, 1992 (start of performance
of Institutional Service Shares), through February 28, 1995, and for the
year ended February 28, 1995, was 3.78% and 2.88%, respectively.
Yield
The Trust's yield for the thirty day period ended February 28, 1995, was
6.60% and 6.35% for Institutional Shares and Institutional Service
Shares, respectively.
The yield for both classes of shares of the Trust is determined by
dividing the net investment income per share (as defined by the
Securities and Exchange Commission) earned by either class of shares
over a thirty-day period by the maximum offering price per share of
either class on the last day of the period. This value is annualized
using semi-annual compounding. This means that the amount of income
generated during the thirty-day period is assumed to be generated each
month over a twelve month period and is reinvested every six months. The
yield does not necessarily reflect income actually earned by the Trust
because of certain adjustments required by the Securities and Exchange
Commission and, therefore, may not correlate to the dividends or other
distributions paid to shareholders.
To the extent that financial institutions and broker/dealers charge fees
in connection with services provided in conjunction with an investment
in either class of shares, performance will be reduced for those
shareholders paying those fees.
Performance Comparisons
The performance of both classes of shares depends upon such variables
as:
   o portfolio quality;
   o average portfolio maturity;
   o type of instruments in which the portfolio is invested;
   o changes in interest rates and market value of portfolio
      securities;
   o changes in the Trust's expenses or either class of Share's
      expenses; and
   o various other factors.
Either class of Shares' performance fluctuates on a daily basis largely
because net earnings and offering price per share fluctuate daily. Both
net earnings and net asset value per share are factors in the
computation of yield and total return.
Investors may use financial publications and/or indices to obtain a
more complete view of the Trust's performance. When comparing
performance, investors should consider all relevant factors such as the
composition of any index used, prevailing market conditions, portfolio
compositions of other funds and methods used to value portfolio
securities and compute offering price. The financial publications and/or
indices which the Trust uses in advertising may include:
   o Lipper Analytical Services, Inc. ranks funds in various categories
      by making comparative calculations using total return. Total
      return assumes the reinvestment of all capital gains distributions
      and income dividends and takes into account any change in net
      asset value over a specific period of time. From time to time, the
      Trust will quote its Lipper ranking in the "U.S. government funds"
      category in advertising and sales literature.
   o Merrill Lynch 1-3 Year Treasury Index is an unmanaged index
      tracking short-term U.S. government securities with maturities
      between 1 and 2.99 years. The index is produced by Merrill Lynch,
      Pierce, Fenner & Smith, Inc.
   o Lehman Brothers Intermediate Government Index is an unmanaged
      index comprised of all publicly issued, non-convertible domestic
      debt of the U.S. government or any agency thereof, or any quasi-
      federal corporation and of corporate debt guaranteed by the U.S.
      government. Only notes and bonds with minimum outstanding
      principal of $1 million and minimum maturity of one year and
      maximum maturity of ten years are included.
   o Merrill Lynch 2-Year Treasury Curve Index is comprised of the most
      recently issued 2-year U.S. Treasury notes. Index returns are
      calculated as total returns for periods of one, three, six, and
      twelve months as well as year-to-date.
   o Merrill Lynch U.S. Treasury Short Term Index (1-2.99 years) is an
      unmanaged index tracking short-term U.S. government securities
      with maturities between 1 and 2.99 years. The index is produced by
      Merrill Lynch, Pierce, Fenner & Smith, Inc.
   o 2-Year Treasury Note--Source: Wall Street Journal, Bloomberg
      Financial Markets, and Telerate.
   o Morningstar, Inc., an independent rating service, is the publisher
      of the bi-weekly Mutual Fund Values. Mutual Fund Values rates more
      than 1,000 NASDQ-listed mutual funds of all types, according to
      their risk-adjusted returns. The maximum rating is five stars, and
      ratings are effective for two weeks.
Advertisements and other sales literature for both classes of shares may
quote total returns which are calculated on nonstandardized base
periods. These total returns also represent the historic change in the
value of an investment in either class of shares based on monthly
reinvestment of dividends over a specified period of time.
Duration
Duration is a commonly used measure of the potential volatility in the
price of a bond, or other fixed income security, or in a portfolio of
fixed income securities, prior to maturity. Volatility is the magnitude
of the change in the price of a bond relative to a given change in the
market rate of interest. A bond's price volatility depends on three
primary variables: the bond's coupon rate; maturity date; and the level
of market yields of similar fixed income securities. Generally, bonds
with lower coupons or longer maturities will be more volatile than bonds
with higher coupons or shorter maturities. Duration combines these
variables into a single measure.
Duration is calculated by dividing the sum of the time-weighted values
of the cash flows of a bond or bonds, including interest and principal
payments, by the sum of the present values of the cash flows.
When the Trust invests in mortgage pass-through securities, its duration
will be calculated in a manner which requires assumptions to be made
regarding future principal prepayments. A more complete description of
this calculation is available upon request from the Trust.
