497 1 form.txt FEDERATED INTERMEDIATE GOVERNMENT FUND, INC. (Formerly, Federated Limited Duration Government Fund, Inc.) ------------------------------------------------------------------------------ Institutional Service Shares Institutional Shares ------------------------------------------------------------------------------ Supplement to current Statement of Additional Information (SAI) dated April 30, 2005. 1. Under the section entitled "Securities in which the Fund Invests" please replace the section entitled "Derivative Contracts" through to and including the subsection entitled "SWAPS" with the following: Derivative Contracts Derivative contracts are financial instruments that require payments based upon changes in the values of designated (or underlying) securities, commodities, financial indices or other assets. Some derivative contracts (such as futures, forwards and options) require payments relating to a future trade involving the underlying asset. Other derivative contracts (such as swaps) require payments relating to the income or returns from the underlying asset. The other party to a derivative contract is referred to as a counterparty. Many derivative contracts are traded on securities or commodities exchanges. In this case, the exchange sets all the terms of the contract except for the price. Investors make payments due under their contracts through the exchange. Most exchanges require investors to maintain margin accounts through their brokers to cover their potential obligations to the exchange. Parties to the contract make (or collect) daily payments to the margin accounts to reflect losses (or gains) in the value of their contracts. This protects investors against potential defaults by the counterparty. Trading contracts on an exchange also allows investors to close out their contracts by entering into offsetting contracts. For example, the Fund could close out an open contract to buy an asset at a future date by entering into an offsetting contract to sell the same asset on the same date. If the offsetting sale price is more than the original purchase price, the Fund realizes a gain; if it is less, the Fund realizes a loss. Exchanges may limit the amount of open contracts permitted at any one time. Such limits may prevent the Fund from closing out a position. If this happens, the Fund will be required to keep the contract open (even if it is losing money on the contract), and to make any payments required under the contract (even if it has to sell portfolio securities at unfavorable prices to do so). Inability to close out a contract could also harm the Fund by preventing it from disposing of or trading any assets it has been using to secure its obligations under the contract. The Fund may also trade derivative contracts over-the-counter (OTC) in transactions negotiated directly between the Fund and the counterparty. OTC contracts do not necessarily have standard terms, so they cannot be directly offset with other OTC contracts. In addition, OTC contracts with more specialized terms may be more difficult to price than exchange traded contracts. Depending upon how the Fund uses derivative contracts and the relationships between the market value of a derivative contract and the underlying asset, derivative contracts may increase or decrease the Fund's exposure to interest rate and credit risks, and may also expose the Fund to liquidity and leverage risks. OTC contracts also expose the Fund to credit risks in the event that a counterparty defaults on the contract. The Fund may trade in the following types of derivative contracts: FUTURES CONTRACTS Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of an underlying asset at a specified price, date, and time. Entering into a contract to buy an underlying asset is commonly referred to as buying a contract or holding a long position in the asset. Entering into a contract to sell an underlying asset is commonly referred to as selling a contract or holding a short position in the asset. Futures contracts are considered to be commodity contracts. The Fund has claimed an exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, is not subject to registration or regulation as a commodity pool operator under that Act. Futures contracts traded OTC are frequently referred to as forward contracts. The Fund can buy or sell financial futures. OPTIONS Options are rights to buy or sell an underlying asset or instrument for a specified price (the exercise price) during, or at the end of, a specified period. The seller (or writer) of the option receives a payment, or premium, from the buyer, which the writer keeps regardless of whether the buyer uses (or exercises) the option. Options can trade on exchanges or in the OTC market and may be bought or sold on a wide variety of underlying assets or instruments, including financial indices, individual securities, and other derivative instruments, such as futures contracts. Options that are written on futures contracts will be subject to margin requirements similar to those applied to futures contracts. Call Options A call option gives the holder (buyer) the right to buy the underlying asset from the seller (writer) of the option. The Fund may use call options in the following ways: |X| Buy call options on financial futures in anticipation of an increase in the value of the underlying asset or instrument; and |X| Write call options on financial futures to generate income from premiums, and in anticipation of a decrease or only limited increase in the value of the underlying asset. If a call written by the Fund is exercised, the Fund foregoes any possible profit from an increase in the market price of the underlying asset over the exercise price plus the premium received. Put Options A put option gives the holder the right to sell the underlying asset to the writer of the option. The Fund may use put options in the following ways: |X| Buy put options on financial futures in anticipation of a decrease in the value of the underlying asset; and |X| Write put options on financial futures to generate income from premiums, and in anticipation of an increase or only limited decrease in the value of the underlying asset. In writing puts, there is a risk that the Fund may be required to take delivery of the underlying asset when its current market price is lower than the exercise price. The Fund may also buy or write options, as needed, to close out existing option positions. SWAPS Swaps are contracts in which two parties agree to pay each other (swap) the returns derived from underlying assets with differing characteristics. Most swaps do not involve the delivery of the underlying assets by either party, and the parties might not own the assets underlying the swap. The payments are usually made on a net basis so that, on any given day, the Fund would receive (or pay) only the amount by which its payment under the contract is less than (or exceeds) the amount of the other party's payment. Swap agreements are sophisticated instruments that can take many different forms, and are known by a variety of names including caps, floors and collars. Common swap agreements that the Fund may use include: Interest Rate Swaps Interest rate swaps are contracts in which one party agrees to make regular payments equal to a fixed or floating interest rate times a stated principal amount of fixed income securities, in return for payments equal to a different fixed or floating rate times the same principal amount, for a specific period. For example, a $10 million LIBOR swap would require one party to pay the equivalent of the London Interbank Offer Rate of interest (which fluctuates) on $10 million principal amount in exchange for the right to receive the equivalent of a stated fixed rate of interest on $10 million principal amount. Caps and Floors Caps and Floors are contracts in which one party agrees to make payments only if an interest rate or index goes above (Cap) or below (Floor) a certain level in return for a fee from the other party.
