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

The  Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 24, 1985. 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. With respect to  this Fund, as of the date of  this
prospectus,  the Board of Trustees (the "Trustees") have established two classes
of  shares,  Institutional  Service   Shares  and  Institutional  Shares.   This
prospectus relates only to Institutional Shares (the "Shares") of the Fund.

Shares  are sold primarily to accounts for which financial institutions act in a
fiduciary or agency capacity, and  other accounts where a financial  institution
maintains  master accounts with an aggregate investment of at least $400 million
in certain  mutual funds  which  are advised  or  distributed by  affiliates  of
Federated Investors. Shares are also made available to financial intermediaries,
public,  and private organizations. In addition,  Shares are designed to provide
an appropriate investment for particular financial institutions that are subject
to government agency regulations, including credit unions, savings associations,
and national banks. An investment  in the Fund serves  as a convenient means  of
accumulating  an  interest in  a  professionally managed,  diversified portfolio
which invests at least 65% of the  value of its total assets in U.S.  government
securities,  all of which government securities  will be adjustable and floating
rate mortgage  securities  which are  issued  or  guaranteed as  to  payment  of
principal   and   interest   by   the   U.S.   government,   its   agencies   or
instrumentalities. 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 Fund.

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

INVESTMENT OBJECTIVE

The  investment objective  of the Fund  is to provide  current income consistent
with minimal  volatility  of principal.  Current  income includes,  in  general,
discount  earned  on U.S.  Treasury bills  and  agency discount  notes, interest
earned on mortgage related securities and other U.S. government securities,  and
short-term  capital gains.  The investment  objective cannot  be changed without
approval of shareholders. The Fund  anticipates that it will experience  minimal
volatility  of principal  due to the  frequent adjustments to  interest rates on
adjustable and floating rate mortgage  securities which comprise the  portfolio.
Of  course, there  can be no  assurance that the  Fund will be  able to maintain
minimal  volatility  of  principal  or  that  it  will  achieve  its  investment
objective.  The Fund endeavors to achieve  its investment objective, however, by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

Except as otherwise noted,  the investment policies described  below may not  be
changed by the Trustees without shareholder approval.

                                       3

The  Fund will limit its investments to those that are permitted for purchase by
federal savings  associations  pursuant  to applicable  rules,  regulations,  or
interpretations of the Office of Thrift Supervision and by federal credit unions
under   the  Federal   Credit  Union  Act   and  the   rules,  regulations,  and
interpretations of the National Credit Union Administration (the "NCUA"). Should
additional permitted investments  be allowed as  a result of  future changes  in
applicable  regulations or  federal laws, the  Fund reserves  the right, without
shareholder approval,  to  make  such investments  consistent  with  the  Fund's
investment  objective,  policies,  and  limitations.  Further,  should  existing
statutes or regulations change so as to cause any securities held by the Fund to
become ineligible for purchase by federal savings associations or federal credit
unions, the Fund will dispose of  those securities at times advantageous to  the
Fund.

As  operated within the above limitations, and pursuant to the Fund's investment
policy, which  may  be  changed  without  shareholder  approval,  to  limit  its
investment  to securities that  are appropriate direct  investments for national
banks, the Fund will also serve as an appropriate vehicle for a national bank as
an investment for its own account.

ACCEPTABLE INVESTMENTS.  The Fund pursues its investment objective by  investing
at  least  65% of  the value  of its  total assets  in a  professionally managed
portfolio of U.S. government securities. As a matter of investment policy, which
may be  changed  without shareholder  approval,  all of  these  U.S.  government
securities  will be adjustable  and floating rate  mortgage securities which are
issued or  guaranteed  as to  payment  of principal  and  interest by  the  U.S.
government, its agencies or instrumentalities.

The  types  of mortgage  securities in  which  the Fund  may invest  include the
following:

    - adjustable rate mortgage securities;

    - collateralized mortgage obligations;

    - real estate mortgage investment conduits; and

    - other securities  collateralized  by  or representing  interests  in  real
      estate  mortgages whose interest rates reset at periodic intervals and are
      issued  or   guaranteed  by   the  U.S.   government,  its   agencies   or
      instrumentalities.

In  addition to  the securities  described above,  the Fund  may also  invest in
direct obligations of the U.S. Treasury, such as U.S. Treasury bills, notes, and
bonds, as well as obligations  of U.S. government agencies or  instrumentalities
which are not collateralized by or represent interests in real estate mortgages,
as described above.

The  Fund may also invest in mortgage  related securities, as defined in section
3(a)(41) of the  Securities Exchange Act  of 1934, which  are issued by  private
entities  such  as  investment  banking  firms  and  companies  related  to  the
construction industry. The privately issued mortgage related securities in which
the Fund may invest include:

    - privately issued securities which are collateralized by pools of mortgages
      in which  each mortgage  is  guaranteed as  to  payment of  principal  and
      interest by an agency or instrumentality of the U.S. government;

                                       4

    - privately issued securities which are collateralized by pools of mortgages
      in  which payment of  principal and interest are  guaranteed by the issuer
      and such guarantee is collateralized by U.S. government securities; and

    - other privately issued securities  in which the  proceeds of the  issuance
      are  invested in mortgage  backed securities and  payment of the principal
      and interest are supported by the credit of any agency or  instrumentality
      of the U.S. government.

The  privately issued mortgage related securities provide for a periodic payment
consisting of  both  interest  and  principal. The  interest  portion  of  these
payments will be distributed by the Fund as income, and the capital portion will
be reinvested.

ADJUSTABLE  RATE MORTGAGE SECURITIES  ("ARMS").  ARMS  are pass-through mortgage
securities with adjustable rather than fixed  interest rates. The ARMS in  which
the  Fund  invests  are  issued  by  Government  National  Mortgage  Association
("GNMA"), Federal National Mortgage Association ("FNMA"), and Federal Home  Loan
Mortgage Corporation ("FHLMC") and are actively traded. The underlying mortgages
which  collateralize ARMS  issued by  GNMA are  fully guaranteed  by the Federal
Housing Administration ("FHA")  or Veterans Administration  ("VA"), while  those
collateralizing  ARMS  issued  by  FHLMC  or  FNMA  are  typically  conventional
residential mortgages  conforming  to  strict  underwriting  size  and  maturity
constraints.

Unlike  conventional bonds, ARMS  pay back principal  over the life  of the ARMS
rather than at maturity.  Thus, a holder  of the ARMS, such  as the Fund,  would
receive  monthly scheduled  payments of principal  and interest  and may receive
unscheduled  principal  payments   representing  payments   on  the   underlying
mortgages.  At the time that a holder of the ARMS reinvests the payments and any
unscheduled prepayments of principal that it receives, the holder may receive  a
rate  of interest which is actually lower than  the rate of interest paid on the
existing ARMS. As a consequence, ARMS may be a less effective means of  "locking
in" long-term interest rates than other types of U.S. government securities.

Not  unlike  other U.S.  government securities,  the market  value of  ARMS will
generally vary inversely with changes in market interest rates. Thus, the market
value of ARMS generally  declines when interest rates  rise and generally  rises
when interest rates decline.

While  ARMS generally entail  less risk of  a decline during  periods of rapidly
rising rates, ARMS may  also have less potential  for capital appreciation  than
other similar investments (e.g. investments with comparable maturities) because,
as  interest  rates decline,  the likelihood  increases  that mortgages  will be
prepaid. Furthermore, if ARMS are purchased at a premium, mortgage  foreclosures
and  unscheduled  principal  payments may  result  in  some loss  of  a holder's
principal investment to the extent of the premium paid. Conversely, if ARMS  are
purchased  at  a  discount,  both  a  scheduled  payment  of  principal  and  an
unscheduled prepayment of principal would increase current and total returns and
would accelerate the  recognition of income,  which would be  taxed as  ordinary
income when distributed to shareholders.

                                       5

COLLATERALIZED  MORTGAGE  OBLIGATIONS  ("CMOS").    CMOs  are  bonds  issued  by
single-purpose,  stand-alone  finance  subsidiaries   or  trusts  of   financial
institutions,  government agencies, investment bankers,  or companies related to
the construction industry. CMOs purchased by the Fund may be:

    - collateralized by pools of mortgages in which each mortgage is  guaranteed
      as to payment of principal and interest by an agency or instrumentality of
      the U.S. government;

    - collateralized  by pools  of mortgages in  which payment  of principal and
      interest is guaranteed by the issuer and such guarantee is  collateralized
      by U.S. government securities; or

    - securities  in which the proceeds of the issuance are invested in mortgage
      securities and payment of the principal and interest are supported by  the
      credit of an agency or instrumentality of the U.S. government.

The  Fund will  only purchase CMO's  which are  investment grade, as  rated by a
nationally recognized statistical rating organization.

REAL ESTATE MORTGAGE INVESTMENT  CONDUITS ("REMICS").   REMICs are offerings  of
multiple  class real estate  mortgage-backed securities which  qualify and elect
treatment as such  under provisions  of the  Internal Revenue  Code. Issuers  of
REMICs  may  take several  forms,  such as  trusts,  partnerships, corporations,
associations or a segregated pool of mortgages. Once REMIC status is elected and
obtained, the entity is not subject to federal income taxation. Instead,  income
is  passed through  the entity and  is taxed to  the person or  persons who hold
interests in the REMIC. A REMIC interest must consist of one or more classes  of
"regular interests," some of which may offer adjustable rates (the type in which
the  Fund primarily  invests), and  a single  class of  "residual interests." To
qualify as a REMIC,  substantially all of  the assets of the  entity must be  in
assets directly or indirectly secured principally by real property.

REGULATORY  COMPLIANCE.   In accordance  with the  Rules and  Regulations of the
NCUA, unless the purchase is made solely to reduce interest-rate risk, the  Fund
will  not invest in  any CMO or REMIC  security that meets  any of the following
three tests: (1) the CMO or REMIC  has an expected average life greater than  10
years;  (2) the average  life of the CMO  or REMIC extends by  more than 4 years
assuming an immediate and  sustained parallel shift in  the yield curve of  plus
300  basis points, or  shortens by more  than 6 years  assuming an immediate and
sustained parallel shift in the  yield curve of minus  300 basis points; or  (3)
the  estimated change in the price of the CMO  or REMIC is more than 17%, due to
an immediate and sustained parallel  shift in the yield  curve of plus or  minus
300 basis points.

Neither  test (1)  nor (2) above  apply to  floating or adjustable  rate CMOs or
REMICs with all of the following  characteristics: (a) the interest rate of  the
instrument  is  reset at  least annually;  (b)  the interest  rate is  below the
contractual cap of the instrument; (c)  the instrument is tied to a  widely-used
market rate; and (d) the instrument varies directly (not inversely) and is reset
in proportion with the index's changes.

The  Fund may not purchase  a residual interest in a  CMO or REMIC. In addition,
the Fund will not purchase zero  coupon securities with maturities greater  than
10 years.

                                       6

RESETS.  The interest rates paid on the ARMS, CMOs, and REMICs in which the Fund
invests generally are readjusted or reset at intervals of one year or less to an
increment  over  some  predetermined interest  rate  index. There  are  two main
categories of indices: those based on U.S. Treasury securities and those derived
from a calculated measure, such as a cost of funds index or a moving average  of
mortgage  rates. Commonly  utilized indices  include the  one-year and five-year
constant maturity Treasury Note rates,  the three-month Treasury Bill rate,  the
180-day  Treasury  Bill  rate,  rates on  longer-term  Treasury  securities, the
National Median Cost  of Funds,  the one-month or  three-month London  Interbank
Offered  Rate (LIBOR), the  prime rate of  a specific bank,  or commercial paper
rates. Some indices, such as the one-year constant maturity Treasury Note  rate,
closely  mirror  changes in  market  interest rate  levels.  Others tend  to lag
changes in market rate levels and tend to be somewhat less volatile.

CAPS AND FLOORS.  The underlying  mortgages which collateralize the ARMS,  CMOs,
and  REMICs in which the Fund invests will frequently have caps and floors which
limit the maximum amount by which the loan rate to the residential borrower  may
change up or down: (1) per reset or adjustment interval and (2) over the life of
the  loan.  Some residential  mortgage  loans restrict  periodic  adjustments by
limiting changes  in  the borrower's  monthly  principal and  interest  payments
rather  than limiting  interest rate changes.  These payment caps  may result in
negative amortization.

The value of mortgage securities  in which the Fund  invests may be affected  if
market interest rates rise or fall faster and farther than the allowable caps or
floors on the underlying residential mortgage loans. An example of the effect of
caps  and floors  on a residential  mortgage loan  may be found  in the Combined
Statement of  Additional Information.  Additionally,  even though  the  interest
rates  on the underlying residential  mortgages are adjustable, amortization and
prepayments may occur, thereby causing the effective maturities of the  mortgage
securities in which the Fund invests to be shorter than the maturities stated in
the underlying mortgages.

TEMPORARY  INVESTMENTS.  For  defensive purposes only, the  Fund may also invest
temporarily in cash and money market instruments during times of unusual  market
conditions  and  to maintain  liquidity.  Money market  instruments  may include
obligations such as:

    - obligations of the U.S. government  or its agencies or  instrumentalities;
      and

    - repurchase agreements.

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  Fund and agree  at the time  of sale  to
repurchase  them at a mutually  agreed upon time and  price within one year from
the date  of  acquisition. To  the  extent that  the  original seller  does  not
repurchase  the securities from the  Fund, the Fund could  receive less than the
repurchase price on any sale of such securities.

LENDING OF PORTFOLIO SECURITIES.   In order to  generate additional income,  the
Fund  may lend portfolio securities  on a short-term or  a long-term basis up to
one-third of the value  of its total assets  to broker/dealers, banks, or  other
institutional  borrowers  of  securities. The  Fund  will only  enter  into loan
arrangements  with  broker/dealers,  banks,  or  other  institutions  which  the
investment  adviser has determined are creditworthy under guidelines established
by the Fund's Board of Trustees and will

                                       7

receive collateral in the form of cash or U.S. government securities equal to at
least 100% of the value of the securities loaned.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS.  The Fund may purchase securities
on a when-issued or delayed delivery basis. These transactions are  arrangements
in which the Fund purchases securities with payment and delivery scheduled for a
future  time. The seller's failure to  complete these transactions may cause the
Fund 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 Fund may pay more/less than the market value of the securities
on the settlement date.

The Fund may dispose of a commitment prior to settlement if the adviser deems it
appropriate to do so. In addition, the Fund may enter into 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 Fund may realize short-term profits  or losses upon the sale of  such
commitments.

PORTFOLIO  TURNOVER.   The Fund  does not  intend to  invest for  the purpose of
seeking short-term profits,  however securities  in its portfolio  will be  sold
whenever  the Fund's investment adviser  believes it is appropriate  to do so in
light of the Fund's investment objective, without regard to the length of time a
particular security may have been held.

INVESTMENT LIMITATIONS

The Fund will not:

    - invest  in  stripped  mortgage  securities,  including  securities   which
      represent  a share  of only  the interest  payments or  only the principal
      payments from underlying mortgage related securities;

    - borrow  money   directly   or  through   reverse   repurchase   agreements
      (arrangements  in  which  the  Fund sells  a  portfolio  instrument  for a
      percentage of its cash  value with an  agreement to buy it  back on a  set
      date)  or pledge securities except,  under certain circumstances, the Fund
      may borrow up to one-third of the value of its net assets and pledge up to
      10% of the value of its total assets to secure such borrowings;

    - lend any of its assets except portfolio securities up to one-third of  the
      value of its total assets;

    - invest  more than  5% of the  value of  its total assets  in securities of
      issuers which  have  records  of  less  than  three  years  of  continuous
      operations,  including the operation  of any predecessor.  With respect to
      the asset-backed securities,  the Fund  will treat the  originator of  the
      asset  pool  as  the  company  issuing  the  securities  for  purposes  of
      determining compliance with this limitation.

The above investment limitations cannot be changed without shareholder approval.
The following  limitation,  however, may  be  changed by  the  Trustees  without
shareholder  approval. Shareholders will be  notified before any material change
in this limitation becomes effective.

                                       8

The Fund 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.

EXPENSES OF THE FUND AND INSTITUTIONAL SHARES

The Fund pays all  of its own  expenses. Holders of  Shares pay their  allocable
portion  of Fund  and Trust  expenses. The Trust  expenses for  which holders of
Shares pay their allocable portion include, but are not limited to: the cost  of
organizing  the Trust and  continuing its existence,  registering the Trust with
federal and state securities authorities,  Trustees' fees, the cost of  meetings
of  Trustees, legal  fees of  the Trust,  association membership  dues, and such
non-recurring and extraordinary items as may arise.

The Fund  expenses for  which  holders of  Shares  pay their  allocable  portion
include,  but are not limited  to: registering the Fund  and Shares of the Fund,
investment advisory services, taxes  and commissions, custodian fees,  insurance
premiums,  auditors' fees, and such non-recurring and extraordinary items as may
arise.

At present, no expenses  are allocated to  the Shares as  a class. However,  the
Trustees  reserve the right to allocate certain expenses to holders of Shares as
they deem appropriate (the  "Class Expenses"). In any  case, the Class  Expenses
would  be limited to: transfer agent fees as identified by the transfer agent as
attributable to  holders of  Shares; printing  and postage  expenses related  to
preparing  and distributing materials such as shareholder reports, prospectuses,
and proxies to current  shareholders; registration fees  paid to the  Securities
and   Exchange  Commission  and  registration  fees  paid  to  state  securities

Trustees' fees incurred as a result of issues relating solely to Shares.

                                       11

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

The  Fund'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 Fund, subtracting the interest of the Shares
in the liabilities of  the Fund and those  attributable to Shares, and  dividing
the remainder by the total number of Shares outstanding. The net asset value for
Shares  will exceed that of Institutional Service  Shares due to the variance in
daily net income realized  by each class as  a result of different  distribution
charges  incurred by  the classes. 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. Shares may
be purchased either by wire or mail.

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

BY WIRE.  To purchase Shares of the Fund by Federal Reserve wire, call the  Fund
before  4:00 p.m.  (Eastern time)  to place  an order.  The order  is considered
received immediately. Payment by federal 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:  State  Street  Bank and  Trust  Company, Boston,
Massachusetts;   Attention:   EDGEWIRE;   For   Credit   to:   Federated    ARMs
Fund--Institutional Shares; Fund Number (this number can be found on the account
statement  or by contacting the Fund); Group  Number or Order Number; Nominee or
Institution Name; ABA Number  011000028. Shares cannot be  purchased on days  on
which  the New York Stock Exchange is closed and on federal holidays restricting
wire transfers.

BY MAIL.  To purchase Shares of the  Fund by mail, send a check made payable  to
Federated   ARMs  Fund--Institutional  Shares  to  the  Fund's  transfer  agent,
Federated Services Company, c/o  State Street Bank and  Trust Company, P.O.  Box
8604,  Boston, Massachusetts 02266-8604. Orders  by mail are considered received
after payment by check is converted  by the transfer agent's bank, State  Street
Bank,  into federal funds.  This is normally  the next business  day after State
Street Bank receives the check.

MINIMUM INVESTMENT REQUIRED

The minimum initial investment  in the Fund is  $25,000 plus any  non-affiliated
bank  or broker's fee, if  applicable. 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  Fund. Accounts  established  through  a  non-
affiliated bank or broker may be subject to a smaller minimum investment.

                                       12

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 Fund. 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 Fund's  portfolio securities  that its  net asset  value might  be
materially  affected; (ii) days  on 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.

EXCHANGING SECURITIES FOR INSTITUTIONAL SHARES

Investors  may exchange certain  U.S. government securities  or a combination of
securities and cash for Shares. The securities  and any cash must have a  market
value  of  at  least $25,000.  The  Fund  reserves the  right  to  determine the
acceptability of securities to be exchanged. Securities accepted by the Fund are
valued in the same manner as the Fund values its assets. Shareholders wishing to
exchange securities should first contact Federated Securities Corp.

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 Fund,  Federated Services Company  maintains a  Share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund.

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, upon instruction  of
the transfer agent, into federal funds. Dividends are

                                       13

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

CAPITAL GAINS

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

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

The  Fund redeems Shares at their net asset value next determined after the Fund
receives the redemption request. Redemptions will  be made on days on which  the
Fund  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  Fund before 4:00  p.m.
(Eastern  time). The proceeds will normally be wired the following business day,
but in no event longer than seven days later, to the shareholder's account at  a
domestic  commercial bank that is a member  of the Federal Reserve System. If at
any time  the Fund  shall determine  it necessary  to terminate  or modify  this
method of redemption, shareholders would be promptly notified.

An  authorization form  permitting the  Fund to  accept telephone  requests must
first be  completed. Authorization  forms and  information on  this service  are
available  from Federated Securities Corp. Telephone redemption instructions may
be recorded. If reasonable procedures  are not followed by  the Fund, it may  be
liable for losses due to unauthorized or fraudulent telephone instructions.

In  the  event  of drastic  economic  or  market changes,  the  shareholders may
experience difficulty in redeeming  by telephone. If such  a case should  occur,
another  method of  redemption, such  as that  discussed in  "Written Requests,"
should be considered.

WRITTEN REQUESTS

Shares may also be redeemed by sending  a written request to the Fund. Call  the
Fund  for specific instructions before redeeming by letter. The shareholder will
be asked to provide in the request his name, the Fund name, the class of Shares,
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 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 Fund, 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
      Exchanges;

                                       14

    - 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 Fund does not accept signatures guaranteed by a notary public.

The  Fund and its transfer agent  have adopted standards for accepting signature
guarantees from the above institutions. The Fund 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 Fund 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  due to
shareholder redemptions.  This  requirement  does not  apply,  however,  if  the
balance falls below $25,000 because of changes in the Fund'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 Fund gives the  shareholder one vote in Trustee elections and
other matters submitted to shareholders for  vote. All shares of each  portfolio
in  the Trust have equal voting rights  except that, in matters affecting only a
particular Fund  or class,  only shares  of that  particular Fund  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 or the Fund'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 Fund shall  be called by the Trustees upon the  written
request of shareholders owning at least 10% of the Trust's outstanding shares of
all portfolios entitled to vote.

MASSACHUSETTS PARTNERSHIP LAW

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

                                       15

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 Fund  will pay  no  federal income  tax because  the  Fund expects  to  meet
requirements  of the Internal Revenue Code,  as amended, applicable to regulated
investment companies and to receive the  special tax treatment afforded to  such
companies.

The  Fund will be  treated as a  single, separate entity  for federal income tax
purposes so that  income (including  capital gains)  and losses  related by  the
Trust's  other portfolios, if  any, will not  be combined for  tax purposes with
those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax  on
any  dividends and  other distributions, including  capital gains distributions,
received. This applies whether dividends and distributions are received in  cash
or  as additional Shares. Distributions representing long-term capital gains, if
any, will be taxable  to shareholders as long-term  capital gains no matter  how
long the shareholders have held the Shares.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

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

    - the Fund is not subject to the Pennsylvania corporate or personal property
      tax; and

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

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

From  time  to  time  the  Fund  advertises  its  total  return  and  yield  for
Institutional Shares.

Total  return represents  the change,  over a specified  period of  time, in the
value of an investment in Institutional Shares 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 Institutional Shares is  calculated by dividing the net  investment
income  per share (as defined by  the Securities and Exchange Commission) earned
by Institutional Shares over a thirty-day period by the offering price per share
of Institutional Shares  on the  last day  of the  period. This  number is  then
annualized using semi-annual compounding. The yield does not necessarily reflect

                                       16

income actually earned by Institutional Shares and, therefore, may not correlate
to the dividends or other distributions paid to shareholders.

The  Institutional  Shares are  sold  without any  sales  load or  other similar
non-recurring charges.

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, total return  and yield of Institutional Shares, for  the
same period, will exceed that of Institutional Service Shares.

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

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

Institutional Service Shares are sold to banks and other institutions that  hold
assets in an agency capacity and rely upon the distribution services provided by
the  distributor  for  the marketing  of  these  shares, as  well  as  to retail
customers of such institutions, and are subject to a minimum initial  investment
of  $25,000. Institutional Service  Shares are sold  at net asset  value and are
distributed pursuant  to a  Rule 12b-1  Plan adopted  by the  Trust whereby  the
distributor  is paid  a fee of  .25 of  1% of the  Institutional Service Shares'
average net assets.

Financial  institutions  and  brokers  providing  sales  and/or   administrative
services  may receive different compensation from  one class of shares than from
another class of shares.

The amount of dividends payable to  holders of Institutional Shares will  exceed
that  of Institutional Service  Shares by the  difference between class expenses
and distribution  and  shareholder service  expenses  borne by  shares  of  each
respective class.

The stated advisory fee is the same for both classes of shares.

FEDERATED ARMS FUND

NOTES TO FINANCIAL STATEMENTS
AUGUST 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Federated  ARMs Fund (the "Fund") is registered under the Investment Company Act
of 1940, as amended (the "Act"), as a diversified, open-end, no-load  management
investment  company.  The Fund  provides  two classes  of  shares: Institutional
Shares and Institutional Service Shares.

(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.

A.  INVESTMENT VALUATIONS--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.  Short-term  securities  with   remaining
    maturities  of sixty  days or  less may be  stated at  amortized cost, which
    approximates value.

B.  REPURCHASE AGREEMENTS--It is the policy of the Fund 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 Fund 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 Fund will  only enter into  repurchase agreements with  banks and  other
    recognized  financial institutions, such as broker/dealers, which are deemed
    by the Fund's adviser to be creditworthy pursuant to 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 Fund  could receive  less than  the repurchase
    price on the sale of collateral securities.

C.  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.

D.  FEDERAL  TAXES--It is the Fund'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 August 31, 1994, the Fund,
    for federal tax purposes,  had a capital  loss carryforward of  $18,535,131,
    which will reduce the Fund's taxable income arising from future net realized
    gains on investments, if any, to the

                                       24

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------
    extent  permitted  by the  Code,  and thus  will  reduce the  amount  of the
    distributions to shareholders which would otherwise be necessary to  relieve
    the  Fund  of any  liability for  federal  tax. Pursuant  to the  Code, such
    capital  loss  carryforward  will  expire  in  2001,  $1,799,433  and  2002,
    $16,735,698.  Additionally, net capital  losses of $52,068,567, attributable
    to security transactions  incurred after  October 31, 1993,  are treated  as
    arising on September 1, 1994, the first day of the Fund's next taxable year.

E.  WHEN-ISSUED  AND  DELAYED  DELIVERY  TRANSACTIONS--The  Fund  may  engage in
    when-issued or delayed delivery  transactions. The Fund 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.

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

G.  DOLLAR  ROLL TRANSACTIONS--The  Fund enters  into dollar  roll transactions,
    with respect to  mortgage securities  issued by  GNMA, FNMA,  and FHLMC,  in
    which  the  Fund loans  mortgage  securities to  financial  institutions and
    simultaneously agrees to  accept substantially similar  (same type,  coupon,
    and  maturity) securities at  a later date  at an agreed  upon price. Dollar
    roll transactions  are  short-term  financing arrangements  which  will  not

(4) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY  FEE--Federated Management,  the Fund's  investment  adviser
(the  "Adviser"), receives  for its services  an annual  investment advisory fee
equal to .60  of 1%  of the  Fund's average daily  net assets.  The Adviser  may
voluntarily  choose to  waive a portion  of its  fee. The Adviser  can modify or
terminate this voluntary waiver at any time at its sole discretion.

                                       26

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------

ADMINISTRATIVE FEE--Federated Administrative Services ("FAS") provides the  Fund
administrative  personnel and services.  Prior to March  1, 1994, these services
were provided at approximate cost. Effective March 1, 1994, the FAS fee is based
on the level  of average  aggregate daily  net assets  of the  funds advised  by
subsidiaries  of  Federated Investors  for  the period.  The  administrative fee
received during the period of the Administrative Services Agreement shall be  at
least $125,000 per portfolio and $30,000 per each additional class of shares.

DISTRIBUTION  AND SHAREHOLDER SERVICES FEE--The  Fund has adopted a Distribution
Plan (the "Plan") pursuant to Rule 12b-1  under the Act. Under the terms of  the
Plan, the Fund will compensate Federated Securities Corp. ("FSC"), the principal
distributor,  from the net assets of the  Fund to finance activities intended to
result in the sale of the Fund's Institutional Service Shares. The Plan provides
that the Fund may  incur distribution expenses  up to .25 of  1% of the  average
daily  net assets of  the Institutional Service  Shares, annually, to compensate
FSC. The distributor may  voluntarily choose to waive  its fee. The  distributor
can  modify  or  terminate  this  voluntary  waiver  at  any  time  at  its sole
discretion.

Under the terms of a  Shareholder Services Agreement with Federated  Shareholder
Services  ("FSS"), the Fund  will pay FSS up  to .25 of 1%  of average daily net
assets of each class  of shares for  the period. This fee  is to obtain  certain
personal services for shareholders and to maintain shareholder accounts.

For  the fiscal year ended August 31, 1994, Institutional Shares did not incur a
shareholder services fee.

TRANSFER  AND  DIVIDEND  DISBURSING   AGENT  FEES--Federated  Services   Company
("FServ")  serves as  transfer and dividend  disbursing agent for  the Fund. The
FServ fee is based on  the size, type, and  number of accounts and  transactions
made by shareholders.

INTERFUND  TRANSACTIONS--During  the  period  ended August  31,  1994,  the Fund
engaged in purchase and sale  transactions with other affiliated funds  pursuant
to  Rule  17a-7  under  the Act,  amounting  to  $588,256,901  and $703,344,890,
respectively. These purchases and sales were  conducted on an arms length  basis
and  transacted  for  cash  consideration only,  at  independent  current market
prices, and without brokerage commissions, fees, or other remuneration.

Certain of the Officers and Trustees of  the Fund are Officers and Directors  or

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

To the Trustees and Shareholders of
FEDERATED ARMs FUND:

We have  audited  the  accompanying  statement  of  assets  and  liabilities  of
Federated  ARMs Fund, including  the portfolio of investments,  as of August 31,
1994, 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  for the periods  presented therein.  These
financial  statements  and financial  highlights are  the responsibility  of the
Fund'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
August 31, 1994, by correspondence with the custodian and brokers. 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  ARMs Fund at August  31, 1994, 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  the  periods presented
therein, in conformity with generally accepted accounting principles.

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

The  Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 24, 1985. 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. With respect to  this Fund, as of the date of  this
prospectus,  the Board of Trustees (the "Trustees") have established two classes
of  shares,  Institutional  Service   Shares  and  Institutional  Shares.   This
prospectus  relates only to  Institutional Service Shares  (the "Shares") of the
Fund.

Shares of the Fund are designed to  give banks and other institutions that  hold
assets in an agency capacity and rely upon the distribution services provided by
the  distributor  for  the marketing  of  these  Shares, as  well  as  to retail
customers of such institutions, a  convenient means of accumulating an  interest
in a professionally managed, diversified portfolio which invests at least 65% of
the  value  of its  total assets  in  U.S. government  securities, all  of which
government securities will be adjustable  and floating rate mortgage  securities
which  are issued or guaranteed  as to payment of  principal and interest by the
U.S. government, its  agencies or  instrumentalities. In addition,  the Fund  is
designed   to  provide  an  appropriate   investment  for  particular  financial
institutions which  are  subject  to government  agency  regulations,  including
credit  unions,  savings associations,  and  national banks.  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 Fund.

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

INVESTMENT OBJECTIVE

The investment objective  of the Fund  is to provide  current income  consistent
with  minimal  volatility of  principal.  Current income  includes,  in general,
discount earned  on U.S.  Treasury  bills and  agency discount  notes,  interest
earned  on mortgage related securities and other U.S. government securities, and
short-term capital gains.  The investment  objective cannot  be changed  without
approval  of shareholders. The Fund anticipates  that it will experience minimal
volatility of principal  due to the  frequent adjustments to  interest rates  on
adjustable  and floating rate mortgage  securities which comprise the portfolio.
Of course, there  can be no  assurance that the  Fund will be  able to  maintain
minimal  volatility  of  principal  or  that  it  will  achieve  its  investment
objective. The Fund endeavors to  achieve its investment objective, however,  by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

Except  as otherwise noted,  the investment policies described  below may not be
changed by the Trustees without shareholder approval.

The Fund will limit its investments to those that are permitted for purchase  by
federal  savings  associations  pursuant to  applicable  rules,  regulations, or
interpretations of the Office of Thrift

                                       3

Supervision and by federal credit unions under the Federal Credit Union Act  and
the  rules,  regulations,  and  interpretations  of  the  National  Credit Union
Administration (the "NCUA"). Should additional permitted investments be  allowed
as  a result of  future changes in  applicable regulations or  federal laws, the
Fund reserves the right, without shareholder approval, to make such  investments
consistent  with  the Fund's  investment  objective, policies,  and limitations.
Further, should  existing statutes  or regulations  change so  as to  cause  any
securities held by the Fund to become ineligible for purchase by federal savings
associations or federal credit unions, the Fund will dispose of those securities
at times advantageous to the Fund.

As  operated within the above limitations, and pursuant to the Fund's investment
policy, which  may  be  changed  without  shareholder  approval,  to  limit  its
investments  to securities that are  appropriate direct investments for national
banks, the Fund will also serve as an appropriate vehicle for a national bank as
an investment for its own account.

ACCEPTABLE INVESTMENTS.  The Fund pursues its investment objective by  investing
at  least  65% of  the value  of its  total assets  in a  professionally managed
portfolio of U.S. government securities. As a matter of investment policy, which
may be  changed  without shareholder  approval,  all of  these  U.S.  government
securities  will be adjustable  and floating rate  mortgage securities which are
issued or  guaranteed  as to  payment  of principal  and  interest by  the  U.S.
government, its agencies or instrumentalities.

The  types  of mortgage  securities in  which  the Fund  may invest  include the
following:

    - adjustable rate mortgage securities;

    - collateralized mortgage obligations;

    - real estate mortgage investment conduits; and

    - other securities  collateralized  by  or representing  interests  in  real
      estate  mortgages whose interest rates reset at periodic intervals and are
      issued  or   guaranteed  by   the  U.S.   government,  its   agencies   or
      instrumentalities.

In  addition to  the securities  described above,  the Fund  may also  invest in
direct obligations of the U.S. Treasury, such as U.S. Treasury bills, notes, and
bonds, as well as obligations  of U.S. government agencies or  instrumentalities
which are not collateralized by or represent interests in real estate mortgages,
as described above.

The  Fund may also invest in mortgage  related securities, as defined in section
3(a)(41) of the  Securities Exchange Act  of 1934, which  are issued by  private
entities  such  as  investment  banking  firms  and  companies  related  to  the
construction industry. The privately issued mortgage related securities in which
the Fund may invest include:

    - privately issued securities which are collateralized by pools of mortgages
      in which  each mortgage  is  guaranteed as  to  payment of  principal  and
      interest by an agency or instrumentality of the U.S. government;

                                       4

    - privately issued securities which are collateralized by pools of mortgages
      in  which payment of  principal and interest are  guaranteed by the issuer
      and such guarantee is collateralized by U.S. government securities; and

    - other privately issued securities  in which the  proceeds of the  issuance
      are  invested in mortgage-backed  securities and payment  of the principal
      and interest are supported by the credit of any agency or  instrumentality
      of the U.S. government.

The  privately issued mortgage related securities provide for a periodic payment
consisting of  both  interest  and  principal. The  interest  portion  of  these
payments will be distributed by the Fund as income, and the capital portion will
be reinvested.

ADJUSTABLE  RATE MORTGAGE SECURITIES  ("ARMS").  ARMS  are pass-through mortgage
securities with adjustable rather than fixed  interest rates. The ARMS in  which
the  Fund  invests  are  issued  by  Government  National  Mortgage  Association
("GNMA"), Federal National Mortgage Association ("FNMA"), and Federal Home  Loan
Mortgage Corporation ("FHLMC") and are actively traded. The underlying mortgages
which  collateralize ARMS  issued by  GNMA are  fully guaranteed  by the Federal
Housing Administration ("FHA")  or Veterans Administration  ("VA"), while  those
collateralizing  ARMS  issued  by  FHLMC  or  FNMA  are  typically  conventional
residential mortgages  conforming  to  strict  underwriting  size  and  maturity
constraints.

Unlike  conventional bonds, ARMS  pay back principal  over the life  of the ARMS
rather than at maturity.  Thus, a holder  of the ARMS, such  as the Fund,  would
receive  monthly scheduled  payments of principal  and interest  and may receive
unscheduled  principal  payments   representing  payments   on  the   underlying
mortgages.  At the time that a holder of the ARMS reinvests the payments and any
unscheduled prepayments of principal that it receives, the holder may receive  a
rate  of interest which is actually lower than  the rate of interest paid on the
existing ARMS. As a consequence, ARMS may be a less effective means of  "locking
in" long-term interest rates than other types of U.S. government securities.

Not  unlike  other U.S.  government securities,  the market  value of  ARMS will
generally vary inversely with changes in market interest rates. Thus, the market
value of ARMS generally  declines when interest rates  rise and generally  rises
when interest rates decline.

While  ARMS generally entail  less risk of  a decline during  periods of rapidly
rising rates, ARMS may  also have less potential  for capital appreciation  than
other similar investments (e.g. investments with comparable maturities) because,
as  interest  rates decline,  the likelihood  increases  that mortgages  will be
prepaid. Furthermore, if ARMS are purchased at a premium, mortgage  foreclosures
and  unscheduled  principal  payments may  result  in  some loss  of  a holder's
principal investment to the extent of the premium paid. Conversely, if ARMS  are
purchased  at  a  discount,  both  a  scheduled  payment  of  principal  and  an
unscheduled prepayment of principal would increase current and total returns and
would accelerate the  recognition of income,  which would be  taxed as  ordinary
income when distributed to shareholders.

COLLATERALIZED  MORTGAGE  OBLIGATIONS  ("CMOS").    CMOs  are  bonds  issued  by
single-purpose,  stand-alone  finance  subsidiaries   or  trusts  of   financial
institutions,  government agencies, investment bankers,  or companies related to
the construction industry. CMOs purchased by the Fund may be:

                                       5

    - collateralized by pools of mortgages in which each mortgage is  guaranteed
      as to payment of principal and interest by an agency or instrumentality of
      the U.S. government;

    - collateralized  by pools  of mortgages in  which payment  of principal and
      interest is guaranteed by the issuer and such guarantee is  collateralized
      by U.S. government securities; or

    - securities  in which the proceeds of the issuance are invested in mortgage
      securities and payment of the principal and interest are supported by  the
      credit of an agency or instrumentality of the U.S. government.

The  Fund will  only purchase CMO's  which are  investment grade, as  rated by a
nationally recognized statistical rating organization.

REAL ESTATE MORTGAGE INVESTMENT  CONDUITS ("REMICS").   REMICs are offerings  of
multiple  class real estate  mortgage-backed securities which  qualify and elect
treatment as such  under provisions  of the  Internal Revenue  Code. Issuers  of
REMICs  may  take several  forms,  such as  trusts,  partnerships, corporations,
associations or a segregated pool of mortgages. Once REMIC status is elected and
obtained, the entity is not subject to federal income taxation. Instead,  income
is  passed through  the entity and  is taxed to  the person or  persons who hold
interests in the REMIC. A REMIC interest must consist of one or more classes  of
"regular interests," some of which may offer adjustable rates (the type in which
the  Fund primarily  invests), and  a single  class of  "residual interests." To
qualify as a REMIC,  substantially all of  the assets of the  entity must be  in
assets directly or indirectly secured principally by real property.

REGULATORY  COMPLIANCE.   In accordance  with the  Rules and  Regulations of the
NCUA, unless the purchase is made solely to reduce interest-rate risk, the  Fund
will  not invest in  any CMO or REMIC  security that meets  any of the following
three tests: (1) the CMO or REMIC  has an expected average life greater than  10
years;  (2) the average  life of the CMO  or REMIC extends by  more than 4 years
assuming an immediate and  sustained parallel shift in  the yield curve of  plus
300  basis points, or  shortens by more  than 6 years  assuming an immediate and
sustained parallel shift in the  yield curve of minus  300 basis points; or  (3)
the  estimated change in the price of the CMO  or REMIC is more than 17%, due to
an immediate and sustained parallel  shift in the yield  curve of plus or  minus
300 basis points.

Neither  test (1)  nor (2) above  apply to  floating or adjustable  rate CMOs or
REMICs with all of the following  characteristics: (a) the interest rate of  the
instrument  is  reset at  least annually;  (b)  the interest  rate is  below the
contractual cap of the instrument; (c)  the instrument is tied to a  widely-used
market rate; and (d) the instrument varies directly (not inversely) and is reset
in proportion with the index's changes.

The  Fund may not purchase  a residual interest in a  CMO or REMIC. In addition,
the Fund will not purchase zero  coupon securities with maturities greater  than
10 years.

RESETS.  The interest rates paid on the ARMS, CMOs, and REMICs in which the Fund
invests generally are readjusted or reset at intervals of one year or less to an
increment  over  some  predetermined interest  rate  index. There  are  two main
categories of indices: those based on U.S. Treasury securities and those derived
from  a   calculated  measure,   such  as   a   cost  of   funds  index   or   a

                                       6

moving average of mortgage rates. Commonly utilized indices include the one-year
and  five-year constant maturity  Treasury Note rates,  the three-month Treasury
Bill rate,  the  180-day  Treasury  Bill rate,  rates  on  longer-term  Treasury
securities,  the National  Median Cost  of Funds,  the one-month  or three-month
London Interbank Offered  Rate (LIBOR), the  prime rate of  a specific bank,  or
commercial  paper rates.  Some indices, such  as the  one-year constant maturity
Treasury Note  rate, closely  mirror  changes in  market interest  rate  levels.
Others  tend to lag changes  in market rate levels and  tend to be somewhat less
volatile.

CAPS AND FLOORS.  The underlying  mortgages which collateralize the ARMS,  CMOs,
and  REMICs in which the Fund invests will frequently have caps and floors which
limit the maximum amount by which the loan rate to the residential borrower  may
change up or down: (1) per reset or adjustment interval and (2) over the life of
the  loan.  Some residential  mortgage  loans restrict  periodic  adjustments by
limiting changes  in  the borrower's  monthly  principal and  interest  payments
rather  than limiting  interest rate changes.  These payment caps  may result in
negative amortization.

The value of mortgage securities  in which the Fund  invests may be affected  if
market interest rates rise or fall faster and farther than the allowable caps or
floors on the underlying residential mortgage loans. An example of the effect of
caps  and floors  on a residential  mortgage loan  may be found  in the Combined
Statement of  Additional Information.  Additionally,  even though  the  interest
rates  on the underlying residential  mortgages are adjustable, amortization and
prepayments may occur, thereby causing the effective maturities of the  mortgage
securities in which the Fund invests to be shorter than the maturities stated in
the underlying mortgages.

TEMPORARY  INVESTMENTS.  For  defensive purposes only, the  Fund may also invest
temporarily in cash and money market instruments during times of unusual  market
conditions  and  to maintain  liquidity.  Money market  instruments  may include
obligations such as:

    - obligations of the U.S. government  or its agencies or  instrumentalities;
      and

    - repurchase agreements.

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  Fund and agree  at the time  of sale  to
repurchase  them at a mutually  agreed upon time and  price within one year from
the date  of  acquisition. To  the  extent that  the  original seller  does  not
repurchase  the securities from the  Fund, the Fund could  receive less than the
repurchase price on any sale of such securities.

LENDING OF PORTFOLIO SECURITIES.   In order to  generate additional income,  the
Fund  may lend portfolio securities  on a short-term or  a long-term basis up to
one-third of the value  of its total assets  to broker/dealers, banks, or  other
institutional  borrowers  of  securities. The  Fund  will only  enter  into loan
arrangements  with  broker/dealers,  banks,  or  other  institutions  which  the
investment  adviser has determined are creditworthy under guidelines established
by the Fund's Board of Trustees and will receive collateral in the form of  cash
or  U.S.  government securities  equal  to at  least 100%  of  the value  of the
securities loaned.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS.  The Fund may purchase securities
on a when-issued or delayed delivery basis. These transactions are  arrangements
in which the Fund purchases

                                       7

securities  with payment and delivery scheduled  for a future time. The seller's
failure to complete these  transactions may cause  the Fund 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 Fund  may pay
more/less than the market value of the securities on the settlement date.

The Fund may dispose of a commitment prior to settlement if the adviser deems it
appropriate to do so. In addition, the Fund may enter into 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 Fund may realize short-term profits  or losses upon the sale of  such
commitments.

PORTFOLIO  TURNOVER.   The Fund  does not  intend to  invest for  the purpose of
seeking short-term profits,  however securities  in its portfolio  will be  sold
whenever  the Fund's investment adviser  believes it is appropriate  to do so in
light of the Fund's investment objective, without regard to the length of time a
particular security may have been held.

INVESTMENT LIMITATIONS

The Fund will not:

    - invest  in  stripped  mortgage  securities,  including  securities   which
      represent  a share  of only  the interest  payments or  only the principal
      payments from underlying mortgage related securities;

    - borrow  money   directly   or  through   reverse   repurchase   agreements
      (arrangements  in  which  the  Fund sells  a  portfolio  instrument  for a
      percentage of its cash  value with an  agreement to buy it  back on a  set
      date)  or pledge securities except,  under certain circumstances, the Fund
      may borrow up to one-third of the value of its net assets and pledge up to
      10% of the value of its total assets to secure such borrowings;

    - lend any of its assets except portfolio securities up to one-third of  the
      value of its total assets; or

    - invest  more than  5% of the  value of  its total assets  in securities of
      issuers which  have  records  of  less  than  three  years  of  continuous
      operations,  including the operation  of any predecessor.  With respect to
      the asset-backed securities,  the Fund  will treat the  originator of  the
      asset  pool  as  the  company  issuing  the  securities  for  purposes  of
      determining compliance with this limitation.

The above investment limitations cannot be changed without shareholder approval.
The following  limitation,  however, may  be  changed by  the  Trustees  without
shareholder  approval. Shareholders will be  notified before any material change
in this limitation becomes effective.

The Fund 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.

                                       8

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.  Pursuant to an investment advisory contract with the Trust,
investment  decisions for the Fund are  made by Federated Management, the Fund's
investment adviser (the "Adviser"),  subject to direction  by the Trustees.  The
Adviser  continually conducts investment  research and supervision  for the Fund
and is responsible for the purchase or sale of portfolio instruments, for  which
it receives an annual fee from the Fund.

ADVISORY  FEES.  The Adviser receives an annual investment advisory fee equal to
.60 of 1% of the  Fund's average daily net  assets. The Adviser may  voluntarily
choose to waive a portion of its fee or reimburse the Fund for certain operating
expenses.  This  does not  include  reimbursement to  the  Fund of  any expenses
incurred by shareholders who use the transfer agent's subaccounting  facilities.
The  Adviser can terminate this voluntary waiver of its advisory fee at any time
in its sole discretion.  The Adviser has also  undertaken to reimburse the  Fund
for operating expenses in excess of limitations established by certain states.

ADVISER'S BACKGROUND.  Federated Management, a Delaware business trust organized
on  April  11, 1989,  is a  registered investment  adviser under  the Investment

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

Federated Securities Corp. is the principal distributor for Shares of the  Fund.
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 Fund will pay to the distributor an amount, computed at an annual rate of up
to .25 of 1% of the average daily net asset value of the Shares, 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 Fund makes  no
payments  to the distributor except as described above. Therefore, the Fund does
not pay for unreimbursed expenses of the distributor, including amounts expended
by the distributor in excess of amounts received by it from the Fund,  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 Fund
under the Distribution Plan.

In addition, the  Fund 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  Shares  to  obtain  certain  personal  services  for
shareholders   and  the   maintenance  of   shareholder  accounts  ("shareholder
services"). The  Fund 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 Fund and Federated  Shareholder
Services.

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

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.

OTHER PAYMENTS TO FINANCIAL INSTITUTIONS.   In addition to periodic payments  to
financial  institutions under  the Distribution and  Shareholder Services Plans,
certain financial institutions may

                                       10

be compensated by the adviser or its affiliates for the continuing investment of
customers' assets  in  certain  funds,  including the  Fund,  advised  by  those
entities.  These payments  will be made  directly by the  distributor or Adviser
from their assets, and will not  be made from the assets  of the Fund or by  the
assessment of a sales charge on Shares.

ADMINISTRATION OF THE FUND

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 Fund.
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 (the "Federated Funds") as specified below:

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

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

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

LEGAL  COUNSEL.   Legal  counsel  is provided  by  Houston, Houston  & Donnelly,
Pittsburgh, Pennsylvania, and  Dickstein, Shapiro &  Morin, L.L.P.,  Washington,
D.C.

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

EXPENSES OF THE FUND AND INSTITUTIONAL SERVICE SHARES

The Fund pays all  of its own  expenses. Holders of  Shares pay their  allocable
portion  of Fund  and Trust  expenses. The Trust  expenses for  which holders of
Shares pay their allocable portion include, but are not limited to: the cost  of
organizing  the Trust and  continuing its existence;  registering the Trust with
federal and state securities authorities,  Trustees' fees, the cost of  meetings
of  Trustees, legal  fees of  the Trust,  association membership  dues, and such
non-recurring and extraordinary items as may arise.

The Fund  expenses for  which  holders of  Shares  pay their  allocable  portion
include,  but are not limited  to: registering the Fund  and Shares of the Fund,
investment advisory services, taxes  and commissions, custodian fees,  insurance
premiums,  auditors' fees, and such non-recurring and extraordinary items as may
arise.

                                       11

At present, the only expenses  allocated to the Shares  as a class are  expenses
under  the Fund's  Rule 12b-1  Plan, which relates  to the  Shares. However, the
Trustees reserve the right to allocate certain expenses to holders of Shares  as
they  deem appropriate (the  "Class Expenses"). In any  case, the Class Expenses
would be limited to: transfer agent fees as identified by the transfer agent  as
attributable  to holders  of Shares;  printing and  postage expenses  related to
preparing and distributing materials such as shareholder reports,  prospectuses,
and  proxies to current  shareholders; registration fees  paid to the Securities
and  Exchange  Commission  and  registration  fees  paid  to  state   securities
commissions;  expenses  related  to  administrative  personnel  and  services as
required to support holders of Shares; legal fees relating solely to Shares; and
Trustees' fees incurred as a result of issues relating solely to Shares.

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

The Fund'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 Fund, subtracting the interest of the  Shares
in  the liabilities of the  Fund and those attributable  to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Institutional Shares will exceed that of Shares due to the variance in daily net
income realized by  each class  as a  result of  different distribution  charges
incurred  by the classes. Such variance will  reflect only accrued net income to
which the shareholders of a particular class are entitled.

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

SHARE PURCHASES

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

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

BY WIRE.  To purchase Shares of the Fund by Federal Reserve wire, call the  Fund
before  4:00 p.m.  (Eastern time)  to place  an order.  The order  is considered
received immediately. Payment by federal 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:  State  Street  Bank and  Trust  Company, Boston,
Massachusetts;   Attention:   EDGEWIRE;   For   Credit   to:   Federated    ARMs
Fund--Institutional Service Shares; Fund Number (this number can be found on the
account  statement or  by contacting  the Fund);  Group Number  or Order Number;
Nominee or Institution Name; ABA Number 011000028. Shares cannot be purchased on
days on which  the New York  Stock Exchange  is closed and  on federal  holidays
restricting wire transfers.

BY  MAIL.  To purchase Shares of the Fund  by mail, send a check made payable to
Federated ARMs Fund-Institutional Service Shares  to the Fund's transfer  agent,
Federated  Services Company, c/o  State Street Bank and  Trust Company, P.O. Box
8604, Boston, Massachusetts 02266-8604. Orders by mail are

                                       12

considered received after payment by check is converted by the transfer  agent's
bank,  State Street Bank, into federal funds. This is normally the next business
day after State Street Bank receives the check.

MINIMUM INVESTMENT REQUIRED

The minimum initial investment  in the Fund is  $25,000 plus any  non-affiliated
bank  or broker's fee, if  applicable. 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  Fund. 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 Fund. 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 Fund's  portfolio securities  that its  net asset  value might  be
materially  affected; (ii) days  on which no Shares  are tendered for redemption
and no orders to purchase Shares are received; and (iii) the following holidays:
New Year's Day, President's  Day, Good Friday,  Memorial Day, Independence  Day,
Labor Day, Thanksgiving Day, and Christmas Day.

EXCHANGING SECURITIES FOR INSTITUTIONAL SERVICE SHARES

Investors  may exchange certain  U.S. government securities  or a combination of
securities and cash for Shares. The securities  and any cash must have a  market
value  of  at  least $25,000.  The  Fund  reserves the  right  to  determine the
acceptability of securities to be exchanged. Securities accepted by the Fund are
valued in the same manner as the Fund values its assets. Shareholders wishing to
exchange securities should first contact Federated Securities Corp.

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 Fund,  Federated Services Company  maintains a  Share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund.

                                       13

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, upon instruction  of
the  transfer agent, into federal  funds. Dividends are automatically reinvested
on payment  dates in  additional Shares  of the  Fund unless  cash payments  are
requested by contacting the Fund.

CAPITAL GAINS

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

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

The Fund redeems Shares at their net asset value next determined after the  Fund
receives  the redemption request. Redemptions will be  made on days on which the
Fund 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  Fund before 4:00 p.m.
(Eastern time). The proceeds will normally be wired the following business  day,
but  in no event longer than seven days later, to the shareholder's account at a
domestic commercial bank that is a member  of the Federal Reserve System. If  at
any  time the  Fund shall  determine it  necessary to  terminate or  modify this
method of redemption, shareholders would be promptly notified.

An authorization  form permitting  the Fund  to accept  telephone requests  must
first  be completed.  Authorization forms  and information  on this  service are
available from Federated Securities Corp. Telephone redemption instructions  may
be  recorded. If reasonable procedures  are not followed by  the Fund, it may be
liable for losses due to unauthorized or fraudulent telephone instructions.

In the  event  of drastic  economic  or  market changes,  the  shareholders  may
experience  difficulty in redeeming  by telephone. If such  a case should occur,
another method  of redemption,  such as  that discussed  in "Written  Requests,"
should be considered.

WRITTEN REQUESTS

Shares  may also be redeemed by sending a  written request to the Fund. Call the
Fund for specific instructions before redeeming by letter. The shareholder  will
be asked to provide in the request his name, the Fund name, the class of Shares,
his account number, and the share or dollar amount

                                       14

requested.  If  Share  certificates  have been  issued,  they  must  be properly
endorsed and should  be sent by  registered or certified  mail 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 Fund, 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
      Exchanges;

    - 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 Fund does not accept signatures guaranteed by a notary public.

The  Fund and its transfer agent  have adopted standards for accepting signature
guarantees from the above institutions. The Fund 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 Fund 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  due to
shareholder redemptions.  This  requirement  does not  apply,  however,  if  the
balance falls below $25,000 because of changes in the Fund'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 Fund gives the  shareholder one vote in Trustee elections and
other matters submitted to shareholders for  vote. All shares of each  portfolio
in  the Trust have equal voting rights  except that, in matters affecting only a
particular Fund  or class,  only shares  of that  particular Fund  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 or the Fund's operation and for the election of Trustees
under certain circumstances.

                                       15

Trustees may be removed by the Trustees or by shareholders at a special meeting.
A special meeting of the Fund shall  be called by the Trustees upon the  written
request of shareholders owning at least 10% of the Trust's outstanding shares of
all portfolios entitled to vote.

MASSACHUSETTS PARTNERSHIP LAW

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

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 Fund  will pay  no  federal income  tax because  the  Fund expects  to  meet
requirements  of the Internal Revenue Code,  as amended, applicable to regulated
investment companies and to receive the  special tax treatment afforded to  such
companies.

The  Fund will be  treated as a  single, separate entity  for federal income tax
purposes so that  income (including  capital gains)  and losses  related by  the
Trust's  other portfolios, if  any, will not  be combined for  tax purposes with
those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax  on
any  dividends and  other distributions, including  capital gains distributions,
received. This applies whether dividends and distributions are received in  cash
or  as additional Shares. Distributions representing long-term capital gains, if
any, will be taxable  to shareholders as long-term  capital gains no matter  how
long the shareholders have held the Shares.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

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

    - the Fund is not subject to the Pennsylvania corporate or personal property
      tax; and

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

                                       16

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  Fund  advertises  its  total  return  and  yield  for
Institutional Service Shares.

Total  return represents  the change,  over a specified  period of  time, in the
value of an  investment in  Institutional Service Shares  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  Institutional Service  Shares is  calculated by  dividing the  net
investment  income  per  share  (as  defined  by  the  Securities  and  Exchange
Commission) earned by Institutional Service  Shares over a thirty-day period  by
the  offering price per share of Institutional Service 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 Institutional
Service Shares  and, therefore,  may not  correlate to  the dividends  or  other
distributions paid to shareholders.

The  Institutional  Service Shares  are  sold without  any  sales load  or other
similar non-recurring charges.

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, total return  and yield of Institutional Shares, for  the
same period, will exceed that of Institutional Service Shares.

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

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

Institutional  Shares  are  sold  primarily  to  accounts  for  which  financial
institutions  act in a fiduciary or agency  capacity, and other accounts where a
financial institution maintains master accounts with an aggregate investment  of
at  least $400 million in certain mutual  funds which are advised or distributed
by affiliates  of  Federated  Investors.  Shares  are  also  made  available  to
financial  intermediaries, public, and private  organizations. A minimum initial
investment of $25,000 over a 90-day period is required. Institutional Shares are
sold at net asset value and are distributed without a Rule 12b-1 Plan.

Financial  institutions  and  brokers  providing  sales  and/or   administrative
services  may receive different compensation from  one class of shares than from
another class of shares.

The amount of dividends payable to  holders of Institutional Shares will  exceed
that  of Institutional Service  Shares by the  difference between class expenses
and distribution  and  shareholder service  expenses  borne by  shares  of  each
respective class.

The stated advisory fee is the same for both classes of shares.

FEDERATED ARMS FUND

NOTES TO FINANCIAL STATEMENTS
AUGUST 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Federated  ARMs Fund (the "Fund") is registered under the Investment Company Act
of 1940, as amended (the "Act"), as a diversified, open-end, no-load  management
investment  company.  The Fund  provides  two classes  of  shares: Institutional
Shares and Institutional Service Shares.

(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.

A.  INVESTMENT VALUATIONS--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.  Short-term  securities  with   remaining
    maturities  of sixty  days or  less may be  stated at  amortized cost, which
    approximates value.

B.  REPURCHASE AGREEMENTS--It is the policy of the Fund 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 Fund 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 Fund will  only enter into  repurchase agreements with  banks and  other
    recognized  financial institutions, such as broker/dealers, which are deemed
    by the Fund's adviser to be creditworthy pursuant to 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 Fund  could receive  less than  the repurchase
    price on the sale of collateral securities.

C.  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.

D.  FEDERAL  TAXES--It is the Fund'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 August 31, 1994, the Fund,
    for federal tax purposes,  had a capital  loss carryforward of  $18,535,131,
    which will reduce the Fund's taxable income arising from future net realized
    gains on investments, if any, to the

                                       24

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------
    extent  permitted  by the  Code,  and thus  will  reduce the  amount  of the
    distributions to shareholders which would otherwise be necessary to  relieve
    the  Fund  of any  liability for  federal  tax. Pursuant  to the  Code, such
    capital  loss  carryforward  will  expire  in  2001,  $1,799,433  and  2002,
    $16,735,698.  Additionally, net capital  losses of $52,068,567, attributable
    to security transactions  incurred after  October 31, 1993,  are treated  as
    arising on September 1, 1994, the first day of the Fund's next taxable year.

E.  WHEN-ISSUED  AND  DELAYED  DELIVERY  TRANSACTIONS--The  Fund  may  engage in
    when-issued or delayed delivery  transactions. The Fund 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.

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

G.  DOLLAR  ROLL TRANSACTIONS--The  Fund enters  into dollar  roll transactions,
    with respect to  mortgage securities  issued by  GNMA, FNMA,  and FHLMC,  in
    which  the  Fund loans  mortgage  securities to  financial  institutions and
    simultaneously agrees to  accept substantially similar  (same type,  coupon,
    and  maturity) securities at  a later date  at an agreed  upon price. Dollar
    roll transactions  are  short-term  financing arrangements  which  will  not
    exceed  twelve months.  The Fund  will use  the proceeds  generated from the
    transactions to invest in short-term investments that may enhance the Fund's
    current yield and total return.

INVESTMENT ADVISORY  FEE--Federated Management,  the Fund's  investment  adviser
(the  "Adviser"), receives  for its services  an annual  investment advisory fee
equal to .60  of 1%  of the  Fund's average daily  net assets.  The Adviser  may

                                       26

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------

ADMINISTRATIVE FEE--Federated Administrative Services ("FAS") provides the  Fund
administrative  personnel and services.  Prior to March  1, 1994, these services
were provided at approximate cost. Effective March 1, 1994, the FAS fee is based
on the level  of average  aggregate daily  net assets  of the  funds advised  by
subsidiaries  of  Federated Investors  for  the period.  The  administrative fee
received during the period of the Administrative Services Agreement shall be  at
least $125,000 per portfolio and $30,000 per each additional class of shares.

DISTRIBUTION  AND SHAREHOLDER SERVICES FEE--The  Fund has adopted a Distribution
Plan (the "Plan") pursuant to Rule 12b-1  under the Act. Under the terms of  the
Plan, the Fund will compensate Federated Securities Corp. ("FSC"), the principal
distributor,  from the net assets of the  Fund to finance activities intended to
result in the sale of the Fund's Institutional Service Shares. The Plan provides
that the Fund may  incur distribution expenses  up to .25 of  1% of the  average
daily  net assets of  the Institutional Service  Shares, annually, to compensate
FSC. The distributor may  voluntarily choose to waive  its fee. The  distributor
can  modify  or  terminate  this  voluntary  waiver  at  any  time  at  its sole
discretion.

Under the terms of a  Shareholder Services Agreement with Federated  Shareholder
Services  ("FSS"), the Fund  will pay FSS up  to .25 of 1%  of average daily net
assets of each class  of shares for  the period. This fee  is to obtain  certain
personal services for shareholders and to maintain shareholder accounts.

For  the fiscal year ended August 31, 1994, Institutional Shares did not incur a
shareholder services fee.

TRANSFER  AND  DIVIDEND  DISBURSING   AGENT  FEES--Federated  Services   Company
("FServ")  serves as  transfer and dividend  disbursing agent for  the Fund. The
FServ fee is based on  the size, type, and  number of accounts and  transactions
made by shareholders.

INTERFUND  TRANSACTIONS--During  the  period  ended August  31,  1994,  the Fund
engaged in purchase and sale  transactions with other affiliated funds  pursuant
to  Rule  17a-7  under  the Act,  amounting  to  $588,256,901  and $703,344,890,
respectively. These purchases and sales were  conducted on an arms length  basis

prices, and without brokerage commissions, fees, or other remuneration.

Certain of the Officers and Trustees of  the Fund are Officers and Directors  or

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

To the Trustees and Shareholders of
FEDERATED ARMs FUND:

We have  audited  the  accompanying  statement  of  assets  and  liabilities  of
Federated  ARMs Fund, including  the portfolio of investments,  as of August 31,
1994, 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  for the periods  presented therein.  These
financial  statements  and financial  highlights are  the responsibility  of the
Fund'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
August 31, 1994, by correspondence with the custodian and brokers. 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  ARMs Fund at August  31, 1994, 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  the  periods presented
therein, in conformity with generally accepted accounting principles.

GENERAL INFORMATION ABOUT THE FUND
- --------------------------------------------------------------------------------
Federated ARMs Fund (the "Fund") was established as a Massachusetts business
trust under a Declaration of Trust dated May 24, 1985. The Declaration of Trust
permits the Fund to offer separate series and classes of shares.

Shares of the Fund are offered in two classes, Institutional Service Shares and
Institutional Shares (individually and collectively referred to as "Shares").
This Combined Statement of Additional Information relates to the above-mentioned
Shares of the Fund.

INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------

The Fund's investment objective is to provide current income consistent with
minimal volatility of principal. Current income includes, in general, discount
earned on U.S. Treasury bills and agency discount notes, interest earned on
mortgage-related securities and other U.S. government securities, and short-term
capital gains. The investment objective cannot be changed without approval of
shareholders. The Fund anticipates that it will experience minimal volatility of
principal due to the frequent adjustments to interest rates on adjustable and
floating rate mortgage securities which comprise the portfolio. Of course, there
can be no assurance that the Fund will be able to maintain minimal volatility of
principal or that it will achieve its investment objective. The Fund endeavors
to achieve its investment objective, however, by following the investment
policies described in the prospectus and this Combined Statement of Additional
Information.

TYPES OF INVESTMENTS

The Fund will invest at least 65% of the value of its total assets in adjustable
and floating rate mortgage securities which are issued or guaranteed as to
payment of principal and interest by the U.S. government, its agencies or
instrumentalities. These securities and other U.S. government or agency
obligations are backed by:

    - the full faith and credit of the U.S. Treasury;

    - the issuer's right to borrow from the U.S. Treasury;

    - the discretionary authority of the U.S. government to purchase certain
      obligations of agencies or instrumentalities; or

    - the credit of the agency or instrumentality issuing the obligations.

Examples of agencies and instrumentalities which may not always receive
financial support from the U.S. government are:

    - Federal Farm Credit Banks;

    - Federal Home Loan Banks;

    - Federal National Mortgage Association;

    - Student Loan Marketing Association; and

    - Federal Home Loan Mortgage Corporation.

    PRIVATELY ISSUED MORTGAGE-RELATED SECURITIES

      Privately issued mortgage-related securities generally represent an
      ownership interest in federal agency mortgage pass-through securities,
      such as those issued by Government National Mortgage Association. The
      terms and characteristics of the mortgage instruments may vary among
      pass-through mortgage loan pools.

      The market for such mortgage-related securities has expanded considerably
      since its inception. The size of the primary issuance market and the
      active participation in the secondary market by securities dealers and
      other investors make government-related pools highly liquid.

    CAPS AND FLOORS

      The value of mortgage-related securities in which the Fund invests may be
      affected if interest rates rise or fall faster and farther than the
      allowable caps on the underlying residential mortgage loans. For example,
      consider a residential mortgage loan with a rate which adjusts annually,
      an initial interest rate of 10%, a 2% per annum interest rate cap, and a
      5% life of loan interest rate cap. If the index against which the
      underlying interest rate on the residential mortgage loan is
      compared--such as the one-year Treasury-- moves up by 3%, the residential
      mortgage loan rate may not increase by more than 2% to 12% the first year.
      As one of the underlying residential mortgages for the securities in which
      the Fund invests, the

                                                                               1

- --------------------------------------------------------------------------------
      residential mortgage would depress the value of the securities and,
      therefore, the net asset value of the Fund. If the index against which the
      interest rate on the underlying residential mortgage loan is compared
      moves up no faster or farther than the cap on the underlying mortgage loan
      allows, or if the index moves down as fast or faster than the floor on the
      underlying mortgage loan allows, the mortgage would maintain or improve
      the value of the securities in which the Fund invests and, therefore, the
      net asset value of the Fund.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an advantageous
price or yield for the Fund. No fees or other expenses, other than normal
transaction costs, are incurred. However, liquid assets of the Fund sufficient
to make payment for the securities to be purchased are segregated on the Fund's
records at the trade date. These assets are marked to market daily and are
maintained until the transaction has been settled. The Fund 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 Fund 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
Fund, the Fund could receive less than the repurchase price on any sale of such
securities. In the event that a defaulting seller files for bankruptcy or
becomes insolvent, disposition of such securities by the Fund might be delayed
pending court action. The Fund believes that under the regular procedures
normally in effect for custody of the Fund's portfolio securities subject to
repurchase agreements, a court of competent jurisdiction would rule in favor of
the Fund and allow retention or disposition of such securities. The Fund will
only enter into repurchase agreements with banks and other recognized financial
institutions, such as broker/dealers, which are deemed by the Fund's adviser to
be creditworthy pursuant to guidelines established by the Board of Trustees (the
"Trustees").

LENDING OF PORTFOLIO SECURITIES

The collateral received when the Fund lends portfolio securities must be valued
daily and, should the market value of the loaned securities increase, the
borrower must furnish additional collateral to the Fund. During the time
portfolio securities are on loan, the borrower pays the Fund any dividends or
interest paid on such securities. Loans are subject to termination at the option
of the Fund or the borrower. The Fund may pay reasonable administrative and
custodial fees in connection with a loan and may pay a negotiated portion of the
interest earned on the cash or equivalent collateral to the borrower or placing
broker.

REVERSE REPURCHASE AGREEMENTS

The Fund may also enter into reverse repurchase agreements. These transactions
are similar to borrowing cash. In a reverse repurchase agreement, the Fund
transfers possession of a portfolio instrument to another person, such as a
financial institution, broker, or dealer, in return for a percentage of the
instrument's market value in cash, and agrees that on a stipulated date in the
future the Fund will repurchase the portfolio instrument by remitting the
original consideration plus interest at an agreed upon rate. The use of reverse
repurchase agreements may enable the Fund to avoid selling portfolio instruments
at a time when a sale may be deemed to be disadvantageous, but the ability to
enter into reverse repurchase agreements does not ensure that the Fund will be
able to avoid selling portfolio instruments at a disadvantageous time.

When effecting reverse repurchase agreements, liquid assets of the Fund, in a
dollar amount sufficient to make payment for the obligations to be purchased,
are segregated at the trade date. These assets are marked to market daily and
are maintained until the transaction is settled.

During the period any reverse repurchase agreements are outstanding, but only to
the extent necessary to assure completion of the reverse repurchase agreements,
the Fund will restrict the purchase of portfolio instruments to money market
instruments maturing on or before the expiration date of the reverse repurchase
agreements.

PORTFOLIO TURNOVER

The Fund 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 Fund's investment objective. For the fiscal years ended August 31, 1994, and
1993, the portfolio turnover rates were 65%, and 36%, respectively.

INVESTMENT LIMITATIONS
- --------------------------------------------------------------------------------
STRIPPED MORTGAGE SECURITIES

The Fund will not invest in stripped mortgage securities, including securities
which represent a share of only the interest payments or only the principal
payments from underlying mortgage related securities.

BUYING ON MARGIN

The Fund will not purchase any securities on margin but may obtain such
short-term credits as may be necessary for the clearance of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may borrow money
and engage in reverse repurchase agreements in amounts up to one-third of the
value of its net assets, including the amounts borrowed.

The Fund will not borrow money or engage in reverse repurchase agreements for
investment leverage, but rather as a temporary, extraordinary, or emergency
measure or to facilitate management of the portfolio by enabling the Fund to
meet redemption requests when the liquidation of portfolio securities is deemed
to be inconvenient or disadvantageous. The Fund will not purchase any securities
while any such borrowings are outstanding.

During the period any reverse repurchase agreements are outstanding, but only to
the extent necessary to assure completion of the reverse repurchase agreements,
the Fund will restrict the purchase of portfolio instruments to money market
instruments maturing on or before the expiration date of the reverse repurchase
agreements.

PLEDGING ASSETS

The Fund will not mortgage, pledge, or hypothecate any assets except to secure
permitted borrowings. In those cases, it may pledge assets having a market value
not exceeding the lesser of the dollar amounts borrowed or 10% of the value of
total assets at the time of the borrowing.

DIVERSIFICATION OF INVESTMENTS

With respect to securities comprising 75% of the value of its total assets, the
Fund will not purchase securities of any one issuer (other than cash, cash
items, or securities issued or guaranteed by the government of the United States
or its agencies or instrumentalities and repurchase agreements collateralized by
U.S. government securities) if, as a result, more than 5% of the value of its
total assets would be invested in securities of that issuer.

INVESTING IN REAL ESTATE

The Fund will not buy or sell real estate, although it may invest in the
securities of companies whose business involves the purchase or sale of real
estate or in securities which are secured by real estate or interests in real
estate.

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities.

UNDERWRITING

The Fund will not underwrite any issue of securities, except as it may be deemed
to be an underwriter under the Securities Act of 1933 in connection with the
sale of securities in accordance with its investment objective, policies, and
limitations.

LENDING CASH OR SECURITIES

The Fund will not lend any of its assets, except portfolio securities up to
one-third of the value of its total assets.

SELLING SHORT

The Fund will not sell securities short.

INVESTING IN ILLIQUID SECURITIES

The Fund 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.

                                                                               3

- --------------------------------------------------------------------------------

INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES

The Fund will not purchase securities of other investment companies, except by
purchases in the open market involving only customary brokerage commissions and
as a result of which not more than 5% of the value of its total assets would be
invested in such securities, or except as part of a merger, consolidation, or
other acquisition.

INVESTING IN NEW ISSUERS

The Fund will not invest more than 5% of the value of its total assets in
securities of issuers which have records of less than three years of continuous
operations, including the operation of any predecessor. With respect to the
asset-backed securities, the Fund will treat the originator of the asset pool as
the company issuing the securities for purposes of determining compliance with
this limitation.

The above investment limitations cannot be changed without shareholder approval.

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 Fund did not engage in reverse repurchase agreements, purchase securities of
other investment companies, borrow money, or invest in illiquid securities in
excess of 5% of the value of its total assets during the last fiscal year and
has no present intent to do so in the coming fiscal year.

For purposes of its policies and limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
having capital, surplus, and undivided profits in excess of $100,000,000 at the
time of investment to be "cash items."

FUND OWNERSHIP

Officers and Trustees own less than 1% of the Fund's outstanding shares.

As of October 5, 1994, the following shareholders of record owned 5% or more of
the Institutional Service Shares of the Fund: Bellco First FCU, Greenwood
Village, Colorado, owned approximately 1,467,074 shares (6.0%); Eagle National
Bank, Miami, Florida, owned approximately 1,644,674 shares (6.7%); and Hilton
Hotels Corp., Beverly Hills, California, owned approximately 2,510,040 shares
(10.2%).

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 FUND

The Fund's investment adviser is Federated Management (the "Adviser"). 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, the Fund, or any shareholder of
the Fund 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, the Adviser receives an annual investment advisory
fee as described in the prospectus. During the fiscal years ended August 31,
1994, 1993, and 1992, the Fund's Adviser earned $14,679,639, $12,533,139, and
$2,278,514, respectively, of which $3,459,009, $4,249,470, and $1,218,007,
respectively, were voluntarily waived because of undertakings to limit the
Fund's expenses.

    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 Fund'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 Fund for
      its expenses over the limitation. If the Fund'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.

8

- --------------------------------------------------------------------------------

OTHER RELATED SERVICES

Affiliates of the Adviser may, from time to time, provide certain electronic
equipment and software to institutional customers 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 Fund for a fee as described in the
prospectus. Prior to March 1, 1994, Federated Administrative Services, Inc.,
also a subsidiary of Federated Investors, served as the Fund's administrator.
(For purposes of this Statement of Additional Information, Federated
Administrative Services and Federated Administrative Services, Inc., may
hereinafter collectively be referred to as the "Administrators".) For the fiscal
year ended August 31, 1994, the Administrators collectively earned $1,429,050,
none of which was waived. For the fiscal years ended August 31, 1993 and 1992,
Federated Administrative Services, Inc. earned $989,451 and $283,048,
respectively. Dr. Henry J. Gailliot, an officer of Federated Management, the
adviser to the Fund, 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. and
Federated Administrative Services.

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 who offer brokerage and research services. These
services may be furnished directly to the Fund or to the Adviser and may
include:

    - advice as to the advisability of investing in securities;

    - security analysis and reports;

    - economic studies;

    - industry studies;

    - receipt of quotations for portfolio evaluations; and

    - 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 The 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.

For the fiscal years ended August 31, 1994, 1993, and 1992, the Fund paid no
brokerage commissions on brokerage transactions.

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 of
the Fund is explained in the respective prospectuses under "Investing in
Institutional Shares," or "Investing in Institutional Service Shares."

DISTRIBUTION PLAN (INSTITUTIONAL SERVICE SHARES ONLY) AND SHAREHOLDER SERVICES
PLAN

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

                                                                               9

- --------------------------------------------------------------------------------
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, by adopting the Distribution
Plan, the Board of Trustees expects that the Fund 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 Fund in
pursuing its investment objectives. By identifying potential investors whose
needs are served by the Fund'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; and (3) enhancing shareholder
recordkeeping systems; and (4) responding promptly to shareholders' requests and
inquiries concerning their accounts.

For the fiscal period ending August 31, 1994, payments in the amount of
$1,097,576 were made pursuant to the Distribution Plan (Insitutional Service
Shares only), of which $395,231 was voluntarily waived. In addition, for this
period, payments in the amount of $395,231 were made pursuant to the Shareholder
Services Plan (Institutional Service Shares).

CONVERSION TO FEDERAL FUNDS

It is the Fund'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 before shareholders begin to
earn dividends. Federated Services Company 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 Fund are described in the prospectus.

DETERMINING VALUE OF SECURITIES

Market values of the Fund's portfolio securities are determined as follows:

    - as provided by an independent pricing service;

    - for short-term obligations, according to the mean between bid and asked
      prices, as furnished by an independent pricing service, or for short-term
      obligations with remaining maturities of 60 days or less at the time of
      purchase, at amortized cost unless the Trustees determines this is not
      fair value; or

    - at fair value as determined in good faith by the Trustees.

Prices provided by independent pricing services may be determined without
relying exclusively on quoted prices. Pricing services may consider:

    - yield;

    - quality;

    - coupon rate;

    - maturity;

    - type of issue;

    - trading characteristics; and

    - other market data.

REDEEMING SHARES
- --------------------------------------------------------------------------------

The Fund redeems Shares at the next computed net asset value after the Fund
receives the redemption request. Redemption procedures are explained in the
respective prospectuses under "Redeeming Institutional Shares," or "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.

10

- --------------------------------------------------------------------------------

EXCHANGING SECURITIES FOR FUND SHARES
- --------------------------------------------------------------------------------

Investors may exchange U.S. government securities they already own for Shares,
or they may exchange a combination of U.S. government securities and cash for
Shares. An investor should forward the securities in negotiable form with an
authorized letter of transmittal to Federated Securities Corp. The Fund will
notify the investor of its acceptance and valuation of the securities within
five business days of their receipt by State Street Bank.

The Fund values securities in the same manner as the Fund values its assets. The
basis of the exchange will depend upon the net asset value of Shares on the day
the securities are valued. One Share will be issued for each equivalent amount
of securities accepted.

Any interest earned on the securities prior to the exchange will be considered
in valuing the securities. All interest, dividends, subscription, or other
rights attached to the securities become the property of the Fund, along with
the securities.

TAX CONSEQUENCES

Exercise of this exchange privilege is treated as a sale for federal income tax
purposes. Depending upon the cost basis of the securities exchanged for Shares,
a gain or loss may be realized by the investor.

TAX STATUS
- --------------------------------------------------------------------------------

THE FUND'S TAX STATUS

The Fund 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 Fund must, among other
requirements:

    - derive at least 90% of its gross income from dividends, interest, and
      gains from the sale of securities;

    - derive less than 30% of its gross income from the sale of securities held
      less than three months;

    - invest in securities within certain statutory limits; and

    - 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 Fund is eligible for the dividends received deduction or exclusion available
to corporations. These dividends, and any short-term capital gains, are taxable
as ordinary income.

    CAPITAL GAINS

      Shareholders will pay federal tax at capital gains rates on long-term
      capital gains distributed to them regardless of how long they have held
      the Shares.

TOTAL RETURN
- --------------------------------------------------------------------------------

The average annual total return for both classes of shares of the Fund is the
average compounded rate of return for a given period that would equate a $1,000
initial investment to the ending redeemable value of that investment. The ending
redeemable value is computed by multiplying the number of shares owned at the
end of the period by the offering price per share at the end of the period. The
number of shares owned at the end of the period is based on the number of shares
purchased at the beginning of the period with $1,000, adjusted over the period
by any additional shares, assuming the monthly reinvestment of all dividends and
distributions.

The Fund's average annual total return for Institutional Shares for the one-year
and five-year periods ended August 31, 1994, and for the period from December 3,
1985 (effective date of the Trust's registration statement) to August 31, 1994,
were .99%, 6.90%, and 6.86%, respectively. The Fund's average annual total
return for Institutional Service Shares for the one year period ended August 31,
1994 and for the period from May 4, 1992 (date of initial public investment) to
August 31, 1994, were .74% and 3.19%, respectively.

                                                                              11

- --------------------------------------------------------------------------------

YIELD
- --------------------------------------------------------------------------------

The yield for both classes of shares of the Fund 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
offering price per share by either class of shares on the last day of the
period. This value is then 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 either
class 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.

The Fund's yield for Institutional Shares for the thirty-day period ended August
31, 1994, was 4.12%. The Fund's yield for Institutional Service Shares was 3.87%
for the same period.

PERFORMANCE COMPARISONS
- --------------------------------------------------------------------------------

The performance of both classes of shares depends upon such variables as:

    - portfolio quality;

    - average portfolio maturity;

    - types of instruments in which the portfolio is invested;

    - changes in interest rates and market value of portfolio securities;

    - changes in the Fund's or either class of Share's expenses; and

    - various other factors.

Either class of Share's performance fluctuates on a daily basis largely because
net earnings and offering price per share fluctuate daily. Both net earnings and
offering price 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 Fund'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 Fund uses in advertising may include:

    - LEHMAN BROTHERS ADJUSTABLE RATE MORTGAGE FUNDS AVERAGE is comprised of all
      agency guaranteed securities with coupons that periodically adjust over a
      spread of a published index.

    - LEHMAN BROTHERS 1-3 YEAR GOVERNMENT INDEX is comprised of all publicly
      issued, non-convertible domestic debt of the U.S. government, or any
      agency thereof, or any quasi-federal corporation. The index also includes
      corporate debt guaranteed by the U.S. government. Only notes and bonds
      with a minimum maturity of one year and maximum maturity of 2.9 years are
      included.

    - LIPPER ANALYTICAL SERVICES, INC., ranks funds in various fund 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 Fund will quote its Lipper
      ranking in the "U.S. Mortgage Funds" category in advertising and sales
      literature.

    - MORNINGSTAR, INC., an independent rating service, is the publisher of the
      bi-weekly Mutual Fund Values. Mutual Fund Values rates more than 1,000
      NASDAQ-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 non-standardized 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.

                                                               314082108

FEDERATED ARMs FUND
- --------------------------------------------------------------------------------

              ANNUAL REPORT FOR FISCAL YEAR ENDED AUGUST 31, 1994

    MANAGEMENT DISCUSSION AND ANALYSIS:

    ----------------------------------------------------------------------------

        Federated  ARMs Fund (the  "Fund") is an  all U.S. government adjustable
    rate fund which is rated AAAf by Standard & Poor's Ratings Group* and Aaa by
    Moody's Investors Service, Inc.* and is managed to target the 1.5 to  2-year
    part  of the yield curve. Since the  Fund's August 31, 1993 fiscal year end,
    assets decreased  to  approximately $1.5  billion.  The Fund  remains  fully
    invested in Adjustable Rate Mortgages ("ARMs") and U.S. Treasuries.

        The  bond market  over the  last year  has endured  a trend  of steadily
    increasing interest rates along the yield curve. Just as the market began to
    recover in January  from the negative  fourth quarter of  1993, the  Federal
    Reserve Board (the "Fed") increased the Federal Funds target rate from 3% to
    3.25%  in early  February in reaction  to a  stronger U.S. economy  and as a
    preemptive strike against any threat of inflation. Interest rates  continued
    to  rise after the  Fed's move due  to market expectations  that further Fed
    tightenings would follow.  Further tightenings did  follow in March,  April,
    May,  and August,  resulting in a  Federal Funds  rate of 4.75%,  as the Fed
    moved toward a more neutral  monetary policy stance from it's  accommodative
    posture in 1993. In response to continued tightening of monetary policy, the
    short  end  of the  curve experienced  the largest  increase in  yields. The
    2-year Treasury  note yield  increased from  3.86% to  6.14% over  the  year
    ending  August  31,  1994.  Although  the ARMs  market  did  not  escape the
    volatility in the Treasury market, the Fund did outperform similar  duration
    Treasury  securities as  well as the  Lehman Brothers ARM  Index. The Fund's
    total rate of return for the fiscal year on Institutional Shares was  .99%**
    and  Institutional Service  Shares was  .74%** compared  to (0.86%)  for the
    Merrill Lynch 2-Year Treasury Note Index and (0.38%) for the Lehman Brothers
    ARM Index.

        The current  portfolio  strategy continues  to  favor a  more  defensive
    approach.   Security  selection  favors  ARM  products  which  are  tied  to
    responsive indices such as the 1-year Constant Maturity Treasury (CMT) Index
    with shorter durations and less interest  rate cap risk. These ARMs  provide
    an investment that will perform well in a stable-to-rising rate environment.
    Management  going  forward  will  continue to  monitor  the  adjustable rate
    mortgage-backed market in  an effort  to maximize relative  value and  total
    return performance.

 *RATINGS ARE SUBJECT TO CHANGE.
**PERFORMANCE   QUOTED  REPRESENTS  PAST   PERFORMANCE.  INVESTMENT  RETURN  AND
  PRINCIPAL VALUE WILL FLUCTUATE  SO THAT AN  INVESTOR'S SHARES, WHEN  REDEEMED,
  MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.
