Shareholder Expense Example (unaudited)

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 September 1, 2009 to February 28, 2010.

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 Account Value 9/1/2009	Ending Account Value 2/28/2010	Expenses Paid During Period1
Actual	$1,000	$1,059.00	$0.00
Hypothetical (assuming a 5% return before expenses)	$1,000	$1,024.79	$0.00

1 Expenses are equal to the Fund's annualized net expense ratio of 0.00%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half-year period).

Portfolio of Investments Summary Table (unaudited)

At February 28, 2010, the Fund's portfolio composition¹ was as follows:

Security Type	Percentage of Total Net Assets2
Asset-Backed Securities	28.1%
Mortgage-Backed Securities3	18.8%
FDIC Guaranteed Debt Securities	16.5%
Corporate Debt Securities	8.3%
Bank Loans	3.3%
U.S. Treasury and Agency Securities4	2.1%
Foreign Debt Securities	0.7%
Derivative Contracts5	0.4%
Cash Equivalents6	23.2%
Other Assets and Liabilities — Net7	(1.4)%
TOTAL	100.0%

1	See the Fund's Prospectus and Statement of Additional Information for a description of these security types.
2	As of the date specified above, the Fund owned shares of one or more affiliated investment companies. For purposes of this table, the affiliated investment company (other than an affiliated money market mutual fund) is not treated as a single portfolio security, but rather the Fund is treated as owning a pro rata portion of each security and each other asset and liability owned by the affiliated investment company. Accordingly, the percentages of total net assets shown in the table will differ from those presented on the Portfolio of Investments.
3	For purposes of this table, Mortgage-Backed Securities include mortgage-backed securities guaranteed by Government Sponsored Entities (GSEs) and collateralized mortgage-backed securities.
4	For purposes of this table, U.S. Treasury and Agency Securities do not include mortgage-backed securities guaranteed by GSEs.
5	Based upon net unrealized appreciation (depreciation) or value of the derivative contracts as applicable. Derivative contracts may consist of futures, forwards, options and swaps. The impact of a derivative contract on the Fund's performance may be larger than its unrealized appreciation (depreciation) or value may indicate. In many cases, the notional value or amount of a derivative contract may provide a better indication of the contract's significance to the portfolio. More complete information regarding the Fund's direct investments in derivative contracts, including unrealized appreciation (depreciation), value, and notional values or amounts of such contracts, can be found in the table at the end of the Portfolio of Investments included in this report.
6	Cash Equivalents include any investments in money market mutual funds and/or overnight repurchase agreements.
7	Assets, other than investments in securities and derivative contracts, less liabilities. See Statement of Assets and Liabilities.

Notes to Financial Statements

February 28, 2010 (unaudited)

1. ORGANIZATION

Federated Core Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company. The Trust consists of four diversified portfolios. The financial statements included herein are only those of Federated Duration Plus Core Fund (formerly Federated Enhanced Duration Active Cash Core Fund) (the “Fund”). The financial statements of the other portfolios are presented separately. The assets of each portfolio are segregated and a shareholder's interest is limited to the portfolio in which shares are held. Each portfolio pays its own expenses. The Fund's investment objective is to provide total return. Currently, the Fund is only available for purchase by other Federated funds and their affiliates, other investment companies or insurance company separate accounts, common or commingled trust funds or similar organizations or entities that are “accredited investors” within the meaning of Regulation D of the Securities Act of 1933.

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 U.S. generally accepted accounting principles (GAAP).

Investment Valuation

In calculating its net asset value (NAV), the Fund generally values investments as follows:

• Fixed-income securities acquired with remaining maturities greater than 60 days are fair valued using price evaluations provided by a pricing service approved by the Board of Trustees (the “Trustees”).
• Fixed-income securities acquired with remaining maturities of 60 days or less are valued at their cost (adjusted for the accretion of any discount or amortization of any premium).
• Shares of other mutual funds are valued based upon their reported NAVs.
• Derivative contracts listed on exchanges are valued at their reported settlement or closing price.
• Over-the-counter (OTC) derivative contracts are fair valued using price evaluations provided by a pricing service approved by the Trustees.

If the Fund cannot obtain a price or price evaluation from a pricing service for an investment, the Fund may attempt to value the investment based upon the mean of bid and asked quotations or fair value the investment based on price evaluations, from one or more dealers. If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, the Fund uses the fair value of the investment determined in accordance with the procedures described below. There can be no assurance that the Fund could purchase or sell an investment at the price used to calculate the Fund's NAV.

Fair Valuation and Significant Events Procedures

The Trustees have authorized the use of pricing services to provide evaluations of the current fair value of certain investments for purposes of calculating the NAV. Factors considered by pricing services in evaluating an investment include the yields or prices of investments of comparable quality, coupon, maturity, call rights and other potential prepayments, terms and type, reported transactions, indications as to values from dealers and general market conditions. Some pricing services provide a single price evaluation reflecting the bid-side of the market for an investment (a “bid” evaluation). Other pricing services offer both bid evaluations and price evaluations indicative of a price between the prices bid and asked for the investment (a “mid” evaluation). The Fund normally uses bid evaluations for U.S. Treasury and Agency securities, mortgage-backed securities and municipal securities. The Fund normally uses mid evaluations for other types of fixed-income securities and OTC derivative contracts. In the event that market quotations and price evaluations are not available for an investment, the fair value of the investment is determined in accordance with procedures adopted by the Trustees.

The Trustees also have adopted procedures requiring an investment to be priced at its fair value whenever the Adviser determines that a significant event affecting the value of the investment has occurred between the time as of which the price of the investment would otherwise be determined and the time as of which the NAV is computed. An event is considered significant if there is both an affirmative expectation that the investment's value will change in response to the event and a reasonable basis for quantifying the resulting change in value. Examples of significant events that may occur after the close of the principal market on which a security is traded, or after the time of a price evaluation provided by a pricing service or a dealer, include:

• With respect to price evaluations of fixed-income securities determined before the close of regular trading on the NYSE, actions by the Federal Reserve Open Market Committee and other significant trends in U.S. fixed-income markets;
• Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded; and
• Announcements concerning matters such as acquisitions, recapitalizations, litigation developments, a natural disaster affecting the issuer's operations or regulatory changes or market developments affecting the issuer's industry.

The Fund may seek to obtain more current quotations or price evaluations from alternative pricing sources. If a reliable alternative pricing source is not available, the Fund will determine the fair value of the investment using another method approved by the Trustees.

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.

Semi-Annual Shareholder Report

9

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, Gains and Losses, Expenses and Distributions

Investment transactions are accounted for on a trade-date basis. Realized gains and losses from investment transactions are recorded on an identified-cost basis. Interest income and expenses are accrued daily. Distributions to shareholders are recorded on the ex-dividend date. Distributions of net investment income are declared and paid monthly.

Premium and Discount Amortization/Paydown Gains and Losses

All premiums and discounts on fixed-income securities, other than mortgage-backed securities, are amortized/accreted. Gains and losses realized on principal payment of mortgage-backed securities (paydown gains and losses) are classified as part of investment income.

Federal Taxes

It is the Fund's policy to comply with the Subchapter M provision of the Internal Revenue Code and to distribute to shareholders each year substantially all of its income. Accordingly, no provision for federal income tax is necessary. As of and during the six months ended February 28, 2010, the Fund did not have a liability for any uncertain tax positions. The Fund recognizes interest and penalties, if any, related to tax liabilities as income tax expense in the Statement of Operations. As of February 28, 2010, tax year 2009 will be subject to examination by the Fund's major tax jurisdictions, which include the United States of America and the Commonwealth of Massachusetts.

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.

Futures Contracts

The Fund purchases and sells financial futures contracts to manage cash flows, enhance yield 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, which is shown as Restricted Cash in the Statement of Assets and Liabilities, 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. There is minimal counterparty risk to the Fund since futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default.

Futures contracts outstanding at period end are listed after the Fund's Portfolio of Investments.

This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $20,278.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated Investment Management Company is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.10% of the Fund's average daily net assets. The Adviser may voluntarily choose to waive any portion of its fee and/or reimburse certain operating expenses of the Fund. The Adviser can modify or terminate this voluntary waiver and/or reimbursement at any time at its sole discretion. For the six months ended February 28, 2010, the Adviser voluntarily waived $436 of its fee and voluntarily reimbursed $48,784 of other operating expenses.

Certain of the Fund's assets are managed by Dix Hills Partners, LLC (the “Sub-Adviser”). Under the terms of the sub-advisory agreement between the Adviser and the Sub-Adviser, the Sub-Adviser has agreed to sub-advise the Fund at no charge.

Administrative Fee

Federated Administrative Services (FAS), under the Administrative Services Agreement, provides the Fund with administrative personnel and services. The fee paid to FAS is based on the average aggregate daily net assets of certain Federated funds as specified below:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150%	on the first $5 billion
0.125%	on the next $5 billion
0.100%	on the next $10 billion

7. LINE OF CREDIT

The Fund participates in a $100,000,000 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 offered to the Fund by PNC Bank at the time of the borrowing. As of February 28, 2010, there were no outstanding loans. During the six months ended February 28, 2010, 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 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 Fund to borrow from other participating affiliated funds. As of February 28, 2010, there were no outstanding loans. During the six months ended February 28, 2010, the program was not utilized.

9. Legal Proceedings

Since October 2003, Federated Investors, Inc. and related entities (collectively, “Federated”), and various Federated funds (Federated Funds) have been 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. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court. Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving another Federated Fund. The Board of the Federated Funds retained the law firm of Dickstein Shapiro LLP to represent the Federated Funds in these lawsuits. Federated and the Federated Funds, and their respective counsel, have been defending this litigation, and none of the Federated Funds remains a defendant in any of the lawsuits (though, the other Federated Fund noted above could potentially receive a recovery in the action alleging excessive advisory fees). Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary 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 Federated Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased Federated Fund redemptions, reduced sales of Federated Fund shares, or other adverse consequences for the Federated Funds.

Evaluation and Approval of Advisory Contract - May 2009

Federated Duration Plus Core Fund
(formerly, Federated Enhanced Duration Active Cash Core Fund (the “Fund”)

The Fund's Board reviewed the Fund's investment advisory and subadvisory contracts at meetings held in May 2009. The Board's decision regarding the contracts 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. Although the Adviser charges the Fund an investment advisory fee for its services, the Adviser has agreed to waive its fee and/or reimburse the Fund so that total fund expenses are zero. In addition, the Adviser or its affiliates may receive compensation for managing assets invested in the Fund.

The Federated funds' Board 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 and subadvisory contracts.

As previously noted, the Adviser charges the Fund an investment advisory fee for its services but has agreed to waive its fee and/or reimburse the Fund so that total fund expenses are zero; however, the Board did consider compensation and benefits received by the Adviser and subadviser, 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 the cost 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 for supplying such services. The Board was aware of these factors and was guided by them in its review of the Fund's advisory and subadvisory contracts 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 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 and subadvisory contracts 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 and subadvisory contracts included review of the Senior Officer's evaluation, accompanying data and additional reports covering such matters as: the Adviser's and subadviser'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 Fund's expenses will remain at zero due to waiver of the investment advisory fee and/or reimbursement of other expenses, 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. These reports cover not only the fees under the advisory contracts, but also 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. Moreover, the Board receives regular reports regarding the institution or elimination of these voluntary waivers.

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 and subadvisory contracts 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 net 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 contracts reflects its determination that Federated's performance and actions provided a satisfactory basis to support the decision to continue the existing arrangements.

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.
