See Notes which are an integral part of the Financial Statements SHAREHOLDER EXPENSE EXAMPLE As a shareholder of the Fund, you incur ongoing costs, including to the extent applicable, management fees, distribution (12b-1) fees and/or shareholder services fees; and other Fund expenses. This Example is intended to help you to understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. It is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from January 1, 2007 to June 30, 2007. ACTUAL EXPENSES The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you incurred over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled "Expenses Paid During Period" to estimate the expenses attributable to your investment during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. Thus, you should not use the hypothetical account values and expenses to estimate the actual ending account balance or your expenses for the period. Rather, these figures are required to be provided to enable you to compare the ongoing costs of investing in the Fund with other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD1 1/1/2007 6/30/2007 ACTUAL $1,000 $1,069.90 $0.26 HYPOTHETICAL (ASSUMING A 5% RETURN BEFORE EXPENSES) $1,000 $1,024.55 $0.25 1 Expenses are equal to the Fund's annualized net expense ratio of 0.05%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

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 (GAAP) in the United States of America. INVESTMENT VALUATION Market values of the Fund's portfolio securities are determined as follows: {circle}for mortgage-backed securities, based on the aggregate investment value of the projected cash flows to be generated by the security, as furnished by an independent pricing service; {circle}for other fixed-income securities, according to prices as furnished by an independent pricing service, except that fixed-income securities with remaining maturities of less than 60 days at the time of purchase are valued at amortized cost; {circle}for investments in other open-end registered investment companies, based on net asset value (NAV); {circle}futures contracts and options are generally valued at market values established by the exchanges on which they are traded at the close of trading on such exchanges. Options traded in the over-the-counter market are generally valued according to the mean between the last bid and the last asked price for the option as provided by an investment dealer or other financial institution that deals in the option. The Board of Directors (the "Directors") may determine in good faith that another method of valuing such investments is necessary to appraise their fair market value; {circle}prices for total return swaps are based upon a valuation model determined by management incorporating underlying reference indexes, interest rates, yield curves and other market data or factors; prices for credit default swaps are furnished by an independent pricing service and are based upon a valuation model incorporating default probabilities, recovery rates and other market data or factors; prices for interest rate swaps are furnished by an independent pricing service and are based upon a valuation model incorporating interest rates, yield curves and other market data or factors; {circle}for equity securities, according to the last sale price or official closing price reported in the market in which they are primarily traded (either a national securities exchange or the over-the-counter market), if available; {circle}in the absence of recorded sales for equity securities, according to the mean between the last closing bid and asked prices; and {circle}for all other securities at fair value as determined in accordance with procedures established by and under the general supervision of the Directors. Prices for fixed-income securities furnished by a pricing service may be based on a valuation matrix which incorporates both dealer-supplied valuations and electronic data processing techniques. Such prices (other than prices of mortgage-backed securities) are generally intended to be indicative of the bid prices currently offered to institutional investors for the securities, except that prices for corporate fixed-income and asset-backed securities traded in the United States are generally intended to be indicative of the mean between such bid prices and asked prices. The Directors have approved the use of such pricing services. A number of pricing services are available, and the Fund may use various pricing services or discontinue the use of any pricing service. Prices provided by independent pricing services may be determined without relying exclusively on quoted prices and may consider institutional trading in similar groups of securities, yield, quality, stability, risk, coupon rate, maturity, type of issue, trading characteristics, and other market data or factors. From time to time, when prices cannot be obtained from an independent pricing service, securities may be valued based on quotes from broker-dealers or other financial institutions that trade the securities. Trading in foreign securities may be completed at times which vary from the closing of the New York Stock Exchange (NYSE). In computing its NAV, the Fund values foreign securities using the latest closing price on the exchange on which they are traded immediately prior to the closing of the NYSE. Certain foreign currency exchange rates are generally determined at the latest rate prior to the closing of the NYSE. Foreign securities quoted in foreign currencies are translated into U.S. dollars at current rates. Events that affect these values and exchange rates may occur between the times at which they are determined and the closing of the NYSE. If such events materially affect the value of portfolio securities, these securities may be valued at their fair value as determined in good faith by the Directors, although the actual calculation is done by others under the direction of Fund management. An event is considered material if there is both an affirmative expectation that the security's value will change in response to the event and a reasonable basis for quantifying the resulting change in value. REPURCHASE AGREEMENTS It is the policy of the Fund to require the other party to a repurchase agreement to transfer to the Fund's custodian or sub-custodian eligible securities or cash with a market value (after transaction costs) at least equal to the repurchase price to be paid under the repurchase agreement. The eligible securities are transferred to accounts with the custodian or sub-custodian in which the Fund holds a "securities entitlement" and exercises "control" as those terms are defined in the Uniform Commercial Code. The Fund has established procedures for monitoring the market value of the transferred securities and requiring the transfer of additional eligible securities if necessary to equal at least the repurchase price. These procedures also allow the other party to require securities to be transferred from the account to the extent that their market value exceeds the repurchase price or in exchange for other eligible securities of equivalent market value. With respect to agreements to repurchase U.S. government securities and cash items, the Fund treats the repurchase agreement as an investment in the underlying securities and not as an obligation of the other party to the repurchase agreement. Other repurchase agreements are treated as obligations of the other party secured by the underlying securities. Nevertheless, the insolvency of the other party or other failure to repurchase the securities may delay the disposition of the underlying securities or cause the Fund to receive less than the full repurchase price. Under the terms of the repurchase agreement, any amounts received by the Fund in excess of the repurchase price and related transaction costs must be remitted to the other party. The Fund may enter into repurchase agreements in which eligible securities are transferred into joint trading accounts maintained by the custodian or sub- custodian for investment companies and other clients advised by the Fund's adviser and its affiliates. The Fund will participate on a pro rata basis with the other investment companies and clients in its share of the securities transferred under such repurchase agreements and in its share of proceeds from any repurchase or other disposition of such securities. INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS Interest income and expenses are accrued daily. Dividend income is recorded on the ex-dividend date. Foreign dividends are recorded on the ex-dividend date or when the Fund is informed of the ex-dividend date. All net income earned and gain/loss (realized and unrealized) will be allocated daily to the shareholders based on their capital contributions to the Fund. The Fund does not currently intend to declare and pay distributions. PREMIUM AND DISCOUNT AMORTIZATION/ PAYDOWN GAINS AND LOSSES All premiums and discounts on fixed-income securities other than mortgage-backed securities are amortized/accreted for financial statement purposes. Gains and losses realized on principal payment of mortgage-backed securities (paydown gains and losses) are classified as part of investment income. FEDERAL TAXES As a partnership, the Fund is not subject to U.S. federal income tax. Instead, each investor reports separately on its own federal income tax return its allocated potion of the Fund's income, gain, losses, deduction and credits. Withholding taxes and where appropriate, deferred withholding taxes on foreign interest, dividends and capital gains have been provided for in accordance with the applicable country's tax rules and rates. 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. Losses may occur on these transactions due to changes in market conditions or the failure of counterparties to perform under the contract. SWAP CONTRACTS Swap contracts involve two parties that agree to exchange the returns (or the differential in rates of return) earned or realized on particular predetermined investments, instruments, indices or other measures. The gross returns to be exchanged or "swapped" between parties are generally calculated with respect to a "notional amount" for a predetermined period of time. The Fund may enter into interest rate, total return, credit default, foreign exchange and other swap agreements. Total return swap agreements involve the commitment to pay or receive an amount generally determined by reference to an interest rate in exchange for a specific market-linked return, based on notional amounts. To the extent that the total return of the security or index underlying the transactions exceeds or falls short of the offsetting interest rate based obligation, the Fund receives or makes a payment to the counterparty. Risks may arise upon entering into swap agreements from the potential inability of the counterparties to meet the terms of their contract from unanticipated changes in the value of the swap agreement. Upfront payments received or paid by the Fund will be reflected as an asset or liability on the Statement of Assets and Liabilities. Changes in the value of swap contracts are included in Net payable for swap contracts on the Statement of Assets and Liabilities, and periodic payments are reported as Net realized gain on swap contracts in the Statement of Operations. For the six months ended June 30, 2007, the Fund had a net realized gain on swap contracts of $2,831,345. Swap contracts outstanding at period end are listed after the Fund's portfolio of investments. FUTURES CONTRACTS The Fund purchases and sells financial futures contracts to manage cashflows, enhance yield and to establish and maintain continual economic exposure to changes in the value of the S&P 500 Index and to potentially reduce transaction costs. Upon entering into a financial futures contract with a broker, the Fund is required to deposit in a segregated account a specified amount of cash or U.S. government securities. Futures contracts are valued daily and unrealized gains or losses are recorded in a "variation margin" account. Daily, the Fund receives from or pays to the broker a specified amount of cash based upon changes in the variation margin account. When a contract is closed, the Fund recognizes a realized gain or loss. Futures contracts have market risks, including the risk that the change in the value of the contract may not correlate with the changes in the value of the underlying securities. For the six months ended June 30, 2007, the Fund had net realized gains on futures contracts of $223,688. Futures contracts outstanding at period end are listed after the Fund's portfolio of investments. RESTRICTED SECURITIES Restricted securities are securities that either: (a) cannot be offered for public sale without first being registered, or being able to take advantage of an exemption from registration, under the Securities Act of 1933; or (b) are subject to contractual restrictions on public sales. In some cases, when a security cannot be offered for public sale without first being registered, the issuer of the restricted security has agreed to register such securities for resale, at the issuer's expense, either upon demand by the Fund or in connection with another registered offering of the securities. Many such restricted securities may be resold in the secondary market in transactions exempt from registration. Restricted securities may be determined to be liquid under criteria established by the Directors. The Fund will not incur any registration costs upon such resales. The Fund's restricted securities are valued at the price provided by dealers in the secondary market or, if no market prices are available, at the fair value as determined in accordance with procedures established by and under the general supervision of the Directors. USE OF ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, expenses and revenues reported in the financial statements. Actual results could differ from those estimated. OTHER Investment transactions are accounted for on a trade date basis. Realized gains and losses from investment transactions are recorded on an identified cost basis. 3. CONTRIBUTIONS/WITHDRAWALS Transactions in shares were as follows: SIX MONTHS YEAR ENDED ENDED 12/31/2006 6/30/2007 Proceeds from contributions 77,881 3,664,540 Fair value of withdrawals - (499,900 ) NET CHANGE RESULTING FROM CONTRIBUTIONS/WITHDRAWALS 77,881 3,164,640 4. FEDERAL TAX INFORMATION At June 30, 2007, the cost of investments for federal tax purposes was $48,323,414. The net unrealized depreciation of investments for federal tax purposes excluding any unrealized depreciation from futures contracts and swap contracts was $36,225. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $54,295 and net unrealized depreciation from investments for those securities having an excess of cost over value of $90,520. 5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER FEE Federated Investment Counseling is the Fund's investment adviser (the "Adviser"), subject to the oversight of the Directors. The Adviser provides investment adviser services at no fee. The Adviser may voluntarily choose to reimburse certain operating expenses of the Fund. The Adviser can modify or terminate this voluntary reimbursement at any time at its sole discretion. For the six months ended June 30, 2007, the Adviser voluntarily reimbursed $57,187 of other operating expenses. ADMINISTRATIVE FEE Federated Administrative Services, Inc. (FASI), under the Administrative Services Agreement, provides the Fund with administrative personnel and services. The fee paid to FASI is based on the average aggregate daily net assets of the Trust as specified below: AVERAGE AGGREGATE DAILY NET ASSETS ADMINISTRATIVE FEE OF THE TRUST 0.150% on the first $5 billion 0.125% on the next $5 billion 0.100% on the next $10 billion 0.075% on assets in excess of $20 billion The administrative fee received during any fiscal year shall be at least $150,000 per portfolio. FASI may voluntarily choose to waive any portion of its fee. FASI can modify or terminate this voluntary waiver at any time at its sole discretion. For the six months ended June 30, 2007, FASI waived its entire fee. GENERAL Certain of the Officers and Directors of the Fund are Officers and Directors or Trustees of the above companies. TRANSACTIONS WITH AFFILIATED COMPANIES Affiliated holdings are mutual funds which are managed by the Adviser or an affiliate of the Adviser.

LINE OF CREDIT The Fund participates in a $150,000,000 unsecured, uncommitted revolving line of credit (LOC) agreement with PNC Bank. The LOC was made available for extraordinary or emergency purposes, primarily for financing redemption payments. Borrowings are charged interest at a rate of 0.65% over the federal funds rate. As of June 30, 2007, there were no outstanding loans. During the six months ended June 30, 2007, the Fund did not utilize the LOC. 8. INTERFUND LENDING Pursuant to an Exemptive Order issued by the Securities and Exchange Commission (SEC), the Fund, along with all other funds advised by subsidiaries of Federated Investors, Inc., may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from other participating affiliated funds. As of June 30, 2007, there were no outstanding loans. During the six months ended June 30, 2007, the program was not utilized. 9. LEGAL PROCEEDINGS Beginning in October 2003, Federated Investors, Inc. and various subsidiaries thereof (including the advisers and distributor for various investment companies, collectively, "Federated"), along with various investment companies sponsored by Federated ("Funds") were named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of Federated-sponsored mutual funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. These lawsuits began to be filed shortly after Federated's first public announcement that it had received requests for information on shareholder trading activities in the Funds from the SEC, the Office of the New York State Attorney General ("NYAG"), and other authorities. In that regard, on November 28, 2005, Federated announced that it had reached final settlements with the SEC and the NYAG with respect to those matters. As Federated previously reported in 2004, it has already paid approximately $8.0 million to certain funds as determined by an independent consultant. As part of these settlements, Federated agreed to pay for the benefit of fund shareholders additional disgorgement and a civil money penalty in the aggregate amount of an additional $72 million. Federated and various Funds have also been named as defendants in several additional lawsuits, the majority of which are now pending in the United States District Court for the Western District of Pennsylvania, alleging, among other things, excessive advisory and Rule 12b-1 fees. The Board of the Funds has retained the law firm of Dickstein Shapiro LLP to represent the Funds in these lawsuits. Federated and the Funds, and their respective counsel, are reviewing the allegations and intend to defend this litigation. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek unquantified damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, the ongoing adverse publicity and/or other developments resulting from the regulatory investigations will not result in increased Fund redemptions, reduced sales of Fund shares, or other adverse consequences for the Funds. 10. RECENT ACCOUNTING PRONOUNCEMENTS In September 2006, FASB released Statement on Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157) which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of FAS 157 will have on the Fund's financial statement disclosures. EVALUATION AND APPROVAL OF ADVISORY CONTRACT MARKET PLUS CORE FUND (THE "FUND") The Fund's Board reviewed the Fund's investment advisory contract at meetings held in May 2007. The Board's decision regarding the contract reflects the exercise of its business judgment on whether to continue the existing arrangements. The Fund is distinctive in that it is designed for the efficient management of a particular asset class and is made available for investment only to other Federated funds and a limited number of other accredited investors. In addition, the Adviser does not charge an investment advisory fee for its services although it or its affiliates may receive compensation for managing assets invested in the Fund. The Federated funds had previously appointed a Senior Officer, whose duties include specified responsibilities relating to the process by which advisory fees are to be charged to a Federated fund. The Senior Officer has the authority to retain consultants, experts, or staff as may be reasonably necessary to assist in the performance of his duties, reports directly to the Board, and may be terminated only with the approval of a majority of the independent members of the Board. The Senior Officer prepared and furnished to the Board an independent written evaluation that covered topics discussed below. The Board considered that evaluation, along with other information, in deciding to approve the advisory contract. As previously noted, the Adviser does not charge an investment advisory fee for its services; however, the Board did consider compensation and benefits received by the Adviser, including fees received for services provided to the Fund by other entities in the Federated organization and research services received by the Adviser from brokers that execute Federated fund trades. The Board is also familiar with and considered judicial decisions concerning allegedly excessive investment advisory fees which have indicated that the following factors may be relevant to an Adviser's fiduciary duty with respect to its receipt of compensation from a fund: the nature and quality of the services provided by the Adviser, including the performance of the Fund; the Adviser's cost of providing the services; the extent to which the Adviser may realize "economies of scale" as the Fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with the Fund; performance and expenses of comparable funds; and the extent to which the independent Board members are fully informed about all facts the Board deems relevant bearing on the Adviser's services and fees. The Board further considered management fees (including any components thereof) charged to institutional and other clients of the Adviser for what might be viewed as like services, and costs to the Adviser and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit and profit margins of the Adviser and its affiliates from supplying such services. The Board was aware of these factors and was guided by them in its review of the Fund's advisory contract to the extent it considered them to be appropriate and relevant, as discussed further below. The Board considered and weighed these circumstances in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to the Federated funds, and was assisted in its deliberations by the advice of independent legal counsel. Throughout the year, the Board has requested and received substantial and detailed information about the Fund and the Federated organization that was in addition to the extensive materials that comprise and accompany the Senior Officer's evaluation. Federated provided much of this information at each regular meeting of the Board, and furnished additional reports in connection with the particular meeting at which the Board's formal review of the advisory contract occurred. Between regularly scheduled meetings, the Board has received information on particular matters as the need arose. Thus, the Board's consideration of the advisory contract included review of the Senior Officer's evaluation, accompanying data and additional reports covering such matters as: the Adviser's investment philosophy, personnel and processes; investment and operating strategies; the Fund's short- and long-term performance, and comments on the reasons for performance; the Fund's investment objectives; the Fund's overall expense structure; the use and allocation of brokerage commissions derived from trading the Fund's portfolio securities (if any); and the nature, quality and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates. The Board also considered the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry and market practices; the Fund's relationship to the Federated family of funds which include a comprehensive array of funds with different investment objectives, policies and strategies which are available for exchange without the incurrence of additional sales charges; compliance and audit reports concerning the Federated funds and the Federated companies that service them (including communications from regulatory agencies), as well as Federated's responses to any issues raised therein; and relevant developments in the mutual fund industry and how the Federated funds and/or Federated are responding to them. The Board's evaluation process is evolutionary. The criteria considered and the emphasis placed on relevant criteria change in recognition of changing circumstances in the mutual fund marketplace. Because the Adviser does not charge the Fund an investment advisory fee the Fund's Board does not consider fee comparisons to other mutual funds or other institutional or separate accounts to be relevant. The Board also received financial information about Federated, including reports on the compensation and benefits Federated derived from its relationships with the Federated funds. Because the Adviser does not charge an investment advisory fee for its services, these reports generally cover fees received by Federated's subsidiaries for providing other services to the Federated funds under separate contracts (e.g., for serving as the Federated funds' administrator). The reports also discussed any indirect benefit Federated may derive from its receipt of research services from brokers who execute Federated fund trades. In addition, the Board considered the fact that, in order for a fund to be competitive in the marketplace, Federated and its affiliates frequently waive non-advisory fees and/or reimburse other expenses and have disclosed to fund investors and/or indicated to the Board their intention to do so in the future, where appropriate. The Board and the Senior Officer also reviewed a report compiled by Federated comparing profitability information for Federated to other publicly held fund management companies. In this regard, the Senior Officer noted the limited availability of such information, but nonetheless concluded that Federated's profit margins did not appear to be excessive and the Board agreed. The Board based its decision to approve the advisory contract on the totality of the circumstances and relevant factors and with a view to past and future long- term considerations. Not all of the factors and considerations identified above were necessarily relevant to the Fund, nor did the Board consider any one of them to be determinative. In particular, due to the unusual nature of the Fund as primarily an internal product with no advisory fee, the Board does not consider the assessment of whether economies of scale would be realized if the Fund were to grow to some sufficient size to be relevant. With respect to the factors that were relevant, the Board's decision to approve the contract reflects its determination that Federated's performance and actions provided a satisfactory basis to support the decision to continue the existing arrangement.

IMPORTANT NOTICE ABOUT FUND DOCUMENT DELIVERY In an effort to reduce costs and avoid duplicate mailings, the Fund(s) intend to deliver a single copy of certain documents to each household in which more than one shareholder of the Fund(s) resides (so-called "householding"), as permitted by applicable rules. The Fund's "householding" program covers its/their Prospectus and Statement of Additional Information, and supplements to each, as well as Semi-Annual and Annual Shareholder Reports and any Proxies or information statements. Shareholders must give their written consent to participate in the "householding" program. The Fund is also permitted to treat a shareholder as having given consent ("implied consent") if (i) shareholders with the same last name, or believed to be members of the same family, reside at the same street address or receive mail at the same post office box, (ii) the Fund gives notice of its intent to "household" at least sixty (60) days before it begins "householding" and (iii) none of the shareholders in the household have notified the Fund(s) or their agent of the desire to "opt out" of "householding." Shareholders who have granted written consent, or have been deemed to have granted implied consent, can revoke that consent and opt out of "householding" at any time: shareholders who purchased shares through an intermediary should contact their representative; other shareholders may call the Fund at 1-800-341-7400.
