Note: The categories of investments are shown as a percentage of total net assets at January 31, 2012.

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in the three broad levels listed below:

Level 1 — quoted prices in active markets for identical securities. Including investment companies with daily net asset values, if applicable.

Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.). Also includes securities valued at amortized cost.

Level 3 — significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

As of January 31, 2012, all investments of the Fund utilized Level 1 inputs in valuing the Fund's assets carried at fair value.

Notes to Financial Statements

January 31, 2012 (unaudited)

1. ORGANIZATION

Federated MDT Series (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 five portfolios. The financial statements included herein are only those of Federated MDT All Cap Core Fund (the “Fund”), a diversified portfolio. 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 offers four classes of shares: Class A Shares, Class C Shares, Class R Shares and Institutional Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is long-term capital appreciation.

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:

Equity securities listed on an exchange or traded through a regulated market system are valued at their last reported sale price or official closing price in their principal exchange or market.
Shares of other mutual funds are valued based upon their reported NAVs.
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), which approximates market value.
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.
For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the purchase price of the security, information obtained by contacting the issuer, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded and public trading in similar securities of the issuer or comparable issuers.

Semi-Annual Shareholder Report

Table Of Contents

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 securities traded in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;
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 Trustees have approved the use of a pricing service to determine the fair value of equity securities traded principally in foreign markets when the Adviser determines that there has been a significant trend in the U.S. equity markets or in index futures trading. For other significant events, 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

The Fund may invest in repurchase agreements for short-term liquidity purposes. 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.

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. Dividend income and distributions to shareholders are 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. Distributions of net investment income are declared and paid annually. Non-cash dividends included in dividend income, if any, are recorded at fair value. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that Class A Shares, Class C Shares, Class R Shares and Institutional Shares may bear distribution services fees, shareholder services fees and certain transfer and dividend disbursing agent fees unique to those classes. For the six months ended January 31, 2012, transfer and dividend disbursing agent fees for the Fund were as follows:

	Transfer and Dividend Disbursing Agent Fees Incurred	Transfer and Dividend Disbursing Agent Fees Reimbursed
Class A Shares	$53,754	$(30,414)
Class C Shares	45,486	(20,923)
Class R Shares	5,388	—
Institutional Shares	30,374	(4.445)
TOTAL	$135,002	$(55,782)

Semi-Annual Shareholder Report

Table Of Contents

Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted using the effective interest rate method.

Federal Taxes

It is the Fund's policy to comply with the Subchapter M provision of the Internal Revenue Code (the “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 January 31, 2012, 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 January 31, 2012, tax years 2008 through 2011 remain subject to examination by the Fund's major tax jurisdictions, which include the United States of America and the Commonwealth of Massachusetts.

The Fund may be subject to taxes imposed by governments of countries in which it invests. Such taxes are generally based on either income or gains earned or repatriated. The Fund accrues and applies such taxes to net investment income, net realized gains and net unrealized gains as income and/or gains are earned.

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.

Other

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.

4. FEDERAL TAX INFORMATION

At January 31, 2012, the cost of investments for federal tax purposes was $94,984,017. The net unrealized appreciation of investments for federal tax purposes was $9,712,235. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $11,960,879 and net unrealized depreciation from investments for those securities having an excess of cost over value of $2,248,644.

At July 31, 2011, the Fund had a capital loss carryforward of $130,504,636 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, thereby reducing the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, a net capital loss incurred in taxable years beginning on or before December 22, 2010 is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010, retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

As a result of the tax-free transfer of assets from Federated MDT Tax Aware/All Cap Core Fund, the use of certain capital loss carryforwards listed above may be limited.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated MDTA LLC is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.75% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, the Adviser waived $123,444 of its fee. In addition, an affiliate of the Adviser reimbursed $55,782 of transfer and dividend disbursing agent fees and expenses.

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
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 and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, FAS waived $27,134 of its fee. The net fee paid to FAS was 0.211% of average daily net assets of the Fund. The Fund is currently being charged the minimum administrative fee; therefore the fee as a percentage of average daily net assets is greater than the amounts presented in the chart above.

Distribution 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 daily net assets of the Fund's Class A Shares, Class C Shares and Class R Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at the following percentages of average daily net assets annually, to compensate FSC:

Share Class Name	Percentage of Average Daily Net Assets of Class
Class A Shares	0.05%
Class C Shares	0.75%
Class R Shares	0.50%

Subject to the terms described in the Expense Limitation note, FSC may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, distribution services fees for the Fund were as follows:

	Distribution Services Fees Incurred	Distribution Services Fees Waived
Class C Shares	$100,132	$ —
Class R Shares	6,839	(175)
TOTAL	$106,971	$(175)

When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the six months ended January 31, 2012, FSC retained $7,778 of fees paid by the Fund. For the six months ended January 31, 2012, the Fund's Class A Shares did not incur a distribution services fee; however, it may begin to incur this fee upon approval of the Trustees.

Sales Charges

Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. For the six months ended January 31, 2012, FSC retained $548 in sales charges from the sale of Class A Shares. FSC also retained $1,248 of CDSC relating to redemptions of Class A Shares and $197 of CDSC relating to redemptions of Class C Shares.

While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Trustees.

General

Certain Officers and Trustees of the Trust are Officers and Directors or Trustees of the above companies.

Transactions Involving Affiliated Holdings

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 January 31, 2012, there were no outstanding loans. During the six months ended January 31, 2012, the Fund did not utilize the LOC.

8. INTERFUND LENDING

Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, 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 January 31, 2012, there were no outstanding loans. During the six months ended January 31, 2012, the program was not utilized.

9. recent accounting pronouncements

In April 2011, the Financial Accounting Standards Board (FASB) released Accounting Standards Update (ASU) No. 2011-03, “Reconsideration of Effective Control for Repurchase Agreements.” This ASU amends FASB Accounting Standards Codification (ASC) Topic 860, “Transfers and Servicing”; specifically the criteria required to determine whether a repurchase agreement and similar agreements should be accounted for as sales of financial assets or secured borrowings with commitments. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. Management has concluded that the adoption of ASU No. 2011-03 is not expected to have a material impact on the Fund's financial statements and the accompanying notes, net assets or results of operations.

In addition, in May 2011, FASB released ASU No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” This ASU amends FASB ASC Topic 820, “Fair Value Measurement,” to establish common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. Management has concluded that the adoption of ASU No. 2011-04 is not expected to have a material impact on the Fund's financial statements and the accompanying notes.

Shareholder Expense Example (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase or redemption payments; and (2) ongoing costs, including management fees and to the extent applicable, 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 August 1, 2011 to January 31, 2012.

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.

Semi-Annual Shareholder Report

Table Of Contents

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) on purchase or redemption payments. 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. In addition, if these transaction costs were included, your costs would have been higher.

	Beginning Account Value 8/1/2011	Ending Account Value 1/31/2012	Expenses Paid During Period¹
Actual:
Class A Shares	$1,000	$1,000.00	$6.79
Class C Shares	$1,000	$995.90	$10.79
Class R Shares	$1,000	$996.80	$9.29
Institutional Shares	$1,000	$1,001.70	$5.53
Hypothetical (assuming a 5% return before expenses):
Class A Shares	$1,000	$1,018.35	$6.85
Class C Shares	$1,000	$1,014.33	$10.89
Class R Shares	$1,000	$1,015.84	$9.37
Institutional Shares	$1,000	$1,019.61	$5.58

1	Expenses are equal to the Fund's annualized net expense ratios, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half-year period). The annualized net expense ratios are as follows:

Class A Shares	1.35%
Class C Shares	2.15%
Class R Shares	1.85%
Institutional Shares	1.10%

Evaluation and Approval of Advisory Contract – May 2011

federated mdt all cap core fund (the “Fund”)

The Fund's Board reviewed the Fund's investment advisory contract at meetings held in May 2011. The Board's decision regarding the contract reflects the exercise of its business judgment on whether to continue the existing arrangements.

In this connection, 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 “Evaluation”). The Board considered that Evaluation, along with other information, in deciding to approve the advisory contract.

During its review of the contract, the Board considered compensation and benefits received by the Adviser. This included the fees received for services provided to the Fund by other entities in the Federated organization and research services (if any) received by the Adviser from brokers that execute Federated fund trades, as well as advisory fees. 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 a fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with a 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 contract to the extent it considered them to be appropriate and relevant, as discussed further below.

Semi-Annual Shareholder Report

Table Of Contents

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 information in connection with the particular meeting at which the Board's formal review of the advisory contract occurred. Between regularly scheduled meetings, the Board also 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 information covering such matters as: the Adviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short- and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in relationship to its particular investment program and certain competitor or “peer group” funds and/or other benchmarks, as appropriate), and comments on the reasons for performance; the Fund's investment objectives; the Fund's expenses (including the advisory fee itself and the overall expense structure of the Fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); 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 range of comparable fees for similar funds in the mutual fund industry; 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.

Table Of Contents

mutual funds more heavily than non-mutual fund products or services because it is believed that they are more relevant. For example, other mutual funds are the products most like the Fund, they are readily available to Fund shareholders as alternative investment vehicles, and they are the type of investment vehicle in fact chosen and maintained by the Fund's investors. The range of their fees and expenses therefore appears to be a generally reliable indication of what consumers have found to be reasonable in the precise marketplace in which the Fund competes. The Fund's ability to deliver competitive performance when compared to its peer group was a useful indicator of how the Adviser is executing the Fund's investment program, which in turn assisted the Board in reaching a conclusion that the nature, extent, and quality of the Adviser's investment management services were such as to warrant continuation of the advisory contract. In this regard, the Senior Officer has reviewed Federated's fees for providing advisory services to products outside the Federated family of funds (e.g., institutional and separate accounts). He concluded that mutual funds and institutional accounts are inherently different products. Those differences include, but are not limited to, different types of targeted investors; being subject to different laws and regulations; different legal structures; different average account sizes; different associated costs; different portfolio management techniques made necessary by different cash flows; and portfolio manager time spent in review of securities pricing. The Senior Officer did not consider these fee schedules to be determinative in judging the appropriateness of mutual fund advisory contracts.

The Senior Officer reviewed information compiled by Federated, using data supplied by independent fund ranking organizations, regarding the performance of, and fees charged by, other mutual funds, noting his view that comparisons to fund peer groups are relevant in judging the reasonableness of proposed fees. He also observed that certain funds may exhibit important differences in their objectives and management techniques when compared to other funds placed in the same peer group by ranking organizations, noting in this connection that the Fund's quantitative investment program is of such a type.

The Fund's performance fell below the median of the relevant peer group for the one-year, three-year and five-year periods covered by the Evaluation. In addition, the Board was informed by the Adviser that, for the same periods, the Fund underperformed its benchmark index for the one-year period, underperformed its benchmark index for the three-year period and underperformed its benchmark index for the five-year period. The Board discussed the Fund's performance with the Adviser and recognized the efforts being undertaken by the Adviser. The Board will continue to monitor these efforts and the performance of the Fund.

Table Of Contents

subsidiaries for providing other services to the Federated funds under separate contracts (e.g., for serving as the Federated funds' administrator). The information also detailed 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 waived fees and/or reimbursed 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 reporting as to the institution or elimination of these voluntary waivers.

Federated furnished information, requested by the Senior Officer, that reported revenues on a fund-by-fund basis and made estimates of the allocation of expenses on a fund-by-fund basis, using allocation methodologies specified by the Senior Officer. The Senior Officer noted that, although they may apply consistent allocation processes, the inherent difficulties in allocating costs (and the unavoidable arbitrary aspects of that exercise) and the lack of consensus on how to allocate those costs may render such allocation information unreliable. The allocation information was considered in the analysis by the Board but was determined to be of limited use.

The Board and the Senior Officer also reviewed information 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 Senior Officer's Evaluation also discussed the notion of possible realization of “economies of scale” as a fund grows larger. The Board considered in this regard that the Adviser has made significant and long-term investments in areas that support all of the Federated funds, such as personnel and processes for the portfolio management, compliance, internal audit, and risk management functions; and systems technology; and that the benefits of these efforts (as well as any economies, should they exist) were likely to be enjoyed by the fund complex as a whole. Finally, the Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the Senior Officer's Evaluation) is compounded by the lack of any common industry practice or general pattern with respect to structuring fund advisory fees with “breakpoints” that serve to reduce the fee as the fund attains a certain size. The Senior Officer did not recommend institution of breakpoints in pricing Federated's fund advisory services at this time.

It was noted in the materials for the Board meeting that for the period covered by the Evaluation, the Fund's investment advisory fee, after waivers and expense reimbursements, if any, was below the median of the relevant peer group. The Board reviewed the fees and other expenses of the Fund with the Adviser and was satisfied that the overall expense structure of the Fund remained competitive.

Semi-Annual Shareholder Report

Table Of Contents

The Senior Officer noted that, considering the totality of the circumstances, and all of the factors referenced within his Evaluation, he had concluded that, subject to comments and recommendations made within his Evaluation, his observations and the information accompanying the Evaluation supported a finding by the Board that the management fees for each of the funds are reasonable and that Federated appeared to provide appropriate administrative services to the Fund for the fees paid. Under these circumstances, no changes were recommended to, and no objection was raised to, the continuation of the Fund's advisory contract. The Board concluded that the nature, quality and scope of services provided the Fund by the Adviser and its affiliates were satisfactory.

In its decision to continue an existing investment advisory contract, the Board was mindful of the potential disruptions of the Fund's operations and various risks, uncertainties and other effects that could occur as a result of a decision to terminate or not renew an advisory contract. In particular, the Board recognized that many shareholders have invested in the Fund on the strength of the Adviser's industry standing and reputation and with the expectation that the Adviser will have a continuing role in providing advisory services to the Fund. Thus, the Board's approval of the advisory contract reflected the fact that it is the shareholders who have effectively selected the Adviser by virtue of having invested in the Fund.

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. 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 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.

1	See the Fund's Prospectus for a description of the principal types of securities in which the Fund invests. 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.
2	For purposes of this table, Mortgage-Backed Securities include mortgage-backed securities guaranteed by Government Sponsored Entities and adjustable rate mortgage-backed securities.
3	Also includes $168,533 held in U.S. Treasuries pledged as collateral to ensure the Fund is able to satisfy the obligations of its outstanding futures contracts.
4	Cash Equivalents include any investments in money market mutual funds and/or overnight repurchase agreements.
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	Assets, other than investments in securities and derivative contracts, less liabilities. See Statement of Assets and Liabilities.

Notes to Financial Statements

January 31, 2012 (unaudited)

1. ORGANIZATION

Federated MDT Series (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 five portfolios. The financial statements included herein are only those of Federated MDT Balanced Fund (the “Fund”), a diversified portfolio. 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 offers four classes of shares: Class A Shares, Class C Shares, Class R Shares and Institutional Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is the possibility of long-term growth of capital and income.

2. SIGNIFICANT ACCOUNTING POLICIES

Investment Valuation

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

Equity securities listed on an exchange or traded through a regulated market system are valued at their last reported sale price or official closing price in their principal exchange or market.
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 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), which approximates market value.
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.
For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the purchase price of the security, information obtained by contacting the issuer, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded and public trading in similar securities of the issuer or comparable issuers.

Semi-Annual Shareholder Report

Table Of Contents

Fair Valuation and Significant Events Procedures

With respect to securities traded in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;
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.

Repurchase Agreements

Table Of Contents

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.

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. Dividend income and distributions to shareholders are 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. Distributions of net investment income are declared and paid annually. Non-cash dividends included in dividend income, if any, are recorded at fair value. The Fund invests in Emerging Markets Fixed Income Core Fund (EMCORE), a portfolio of Federated Core Trust II, L.P., which is a limited partnership established under the laws of the state of Delaware. The Fund records daily its proportionate share of income, expenses, realized and unrealized gains and losses from EMCORE. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that Class A Shares, Class C Shares, Class R Shares and Institutional Shares may bear distribution services fees, shareholder services fees, account administration fees and certain transfer and dividend disbursing agent fees unique to those classes. For the six months ended January 31, 2012, transfer and dividend disbursing agent fees and account administration fees for the Fund were as follows:

	Transfer and Dividend Disbursing Agent Fees Incurred	Transfer and Dividend Disbursing Agent Fees Reimbursed	Account Administration Fees Incurred
Class A Shares	$50,202	$(17,504)	$7,279
Class C Shares	28,002	(4,249)	25,575
Class R Shares	987	—	—
Institutional Shares	26,428	(2,107)	—
TOTAL	$105,619	$(23,860)	$32,854

Semi-Annual Shareholder Report

Table Of Contents

Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization/Paydown Gains and Losses

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

Federal Taxes

When-Issued and Delayed Delivery Transactions

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 enters into interest rate, total return, credit default, currency and other swap agreements. 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.

The Fund uses credit default swaps to manage exposure to a given issuer or sector by either selling protection to increase exposure, or buying protection to reduce exposure. The “buyer” in a credit default swap is obligated to pay the “seller” a periodic stream of payments over the term of the contract provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or the “par value,” of the reference obligation in exchange for the reference obligation. In connection with these agreements, securities may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and Semi-Annual Shareholder Report

Table Of Contents

recourse in the event of default or bankruptcy/insolvency. Recovery values are assumed by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is typically determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specific valuation method, are used to calculate the settlement value. The maximum amount of the payment that may occur, as a result of a credit event payable by the protection seller, is equal to the notional amount of the underlying index or security. The Fund's maximum risk of loss from counterparty credit risk, either as the protection buyer or as the protection seller, is the fair value of the contract. This risk is mitigated by having a master netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund's exposure to the counterparty.

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 “Swaps, at value” on the Statement of Assets and Liabilities, and periodic payments are reported as “Net realized gain (loss) on swap contracts” on the Statement of Operations.

At January 31, 2012, the Fund had no outstanding swap contracts.

The average notional value of credit default swap contracts held by the Fund throughout the period was $2,857,143. This is based on amounts held as of each month-end throughout the fiscal period.

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 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.

The average notional value of long and short futures contracts held by the Fund throughout the period was $8,267,397 and $23,500,346, respectively. This is based on amounts held as of each month-end throughout the fiscal period.

Restricted Securities

The Fund may purchase securities which are considered restricted. 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 Semi-Annual Shareholder Report

Table Of Contents

transactions exempt from registration. Restricted securities may be determined to be liquid under criteria established by the Trustees. 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 Trustees.

Additional information on restricted securities, excluding securities purchased under Rule 144A that have been deemed liquid by the Trustees, if applicable, held at January 31, 2012, is as follows:

4. FEDERAL TAX INFORMATION

At January 31, 2012, the cost of investments for federal tax purposes was $127,233,171. The net unrealized appreciation of investments for federal tax purposes excluding any unrealized appreciation/depreciation resulting from futures contracts was $10,217,159. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $12,258,797 and net unrealized depreciation from investments for those securities having an excess of cost over value of $2,041,638.

At July 31, 2011, the Fund had a capital loss carryforward of $58,271,651 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, thereby reducing the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, a net capital loss incurred in taxable years beginning on or before December 22, 2010, is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010, retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

The following schedule summarizes the Fund's short-term and long-term capital loss carryforwards and expiration year:

Expiration Year	Short-Term	Long-Term	Total
2017	$27,291,745	NA	$27,291,745
2018	$30,979,906	NA	$30,979,906

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated MDTA LLC is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.75% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, the Adviser voluntarily waived $145,589 of its fee. In addition, for the six months ended January 31, 2012, an affiliate of the Adviser voluntarily reimbursed $23,860 of transfer and dividend disbursing agent fees and expenses.

Semi-Annual Shareholder Report

Table Of Contents

Certain of the Fund's assets are managed by Federated Investment Management Company (the “Sub-Adviser”). Under the terms of a sub-advisory agreement between the Adviser and the Sub-Adviser, the Sub-Adviser receives an allocable portion of the Fund's adviser fee. The fee is paid by the Adviser out of its resources and is not an incremental Fund expense. For the six months ended January 31, 2012, the Sub-Adviser earned a fee of $61,189.

Administrative Fee

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
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 and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, FAS waived $26,965 of its fee. The net fee paid to FAS was 0.159% of average daily net assets of the Fund. The Fund is currently being charged the minimum administrative fee; therefore the fee as a percentage of average daily net assets is greater than the amounts presented in the chart above.

Distribution Services Fee

Share Class Name	Percentage of Average Daily Net Assets of Class

Evaluation and Approval of Advisory Contract – May 2011

federated mdt balanced fund (the “Fund”)

The Fund's Board reviewed the Fund's investment advisory and subadvisory contracts at meetings held in May 2011. The Board's decision regarding these contracts reflects the exercise of its business judgment on whether to continue the existing arrangements.

During its review of these contracts, the Board considered compensation and benefits received by the Adviser and subadviser. This included the fees received for services provided to the Fund by other entities in the Federated organization and research services (if any) received by the Adviser from brokers that execute Federated fund trades, as well as advisory fees. 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 a fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with a 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 and subadviser 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.

Semi-Annual Shareholder Report

Table Of Contents

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 information 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 also 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 information covering such matters as: the Adviser's and subadviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short- and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in relationship to its particular investment program and certain competitor or “peer group” funds and/or other benchmarks, as appropriate), and comments on the reasons for performance; the Fund's investment objectives; the Fund's expenses (including the advisory fee itself and the overall expense structure of the Fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); 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 range of comparable fees for similar funds in the mutual fund industry; 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.

Semi-Annual Shareholder Report

Table Of Contents

With respect to the Fund's performance and expenses in particular, the Board has found the use of comparisons to other mutual funds with comparable investment programs to be relevant, given the high degree of competition in the mutual fund business. The Board focused on comparisons with other similar mutual funds more heavily than non-mutual fund products or services because it is believed that they are more relevant. For example, other mutual funds are the products most like the Fund, they are readily available to Fund shareholders as alternative investment vehicles, and they are the type of investment vehicle in fact chosen and maintained by the Fund's investors. The range of their fees and expenses therefore appears to be a generally reliable indication of what consumers have found to be reasonable in the precise marketplace in which the Fund competes. The Fund's ability to deliver competitive performance when compared to its peer group was a useful indicator of how the Adviser is executing the Fund's investment program, which in turn assisted the Board in reaching a conclusion that the nature, extent, and quality of the Adviser's investment management services were such as to warrant continuation of the advisory contract. In this regard, the Senior Officer has reviewed Federated's fees for providing advisory services to products outside the Federated family of funds (e.g., institutional and separate accounts). He concluded that mutual funds and institutional accounts are inherently different products. Those differences include, but are not limited to, different types of targeted investors; being subject to different laws and regulations; different legal structures; different average account sizes; different associated costs; different portfolio management techniques made necessary by different cash flows; and portfolio manager time spent in review of securities pricing. The Senior Officer did not consider these fee schedules to be determinative in judging the appropriateness of mutual fund advisory contracts.

The Fund's performance fell below the median of the relevant peer group for the one-year, three-year and five-year periods covered by the Evaluation. The Board discussed the Fund's performance with the Adviser and recognized the efforts being undertaken by the Adviser. The Board will continue to monitor these efforts and the performance of the Fund.

Semi-Annual Shareholder Report

Table Of Contents

The Senior Officer noted that, considering the totality of the circumstances, and all of the factors referenced within his Evaluation, he had concluded that, subject to comments and recommendations made within his Evaluation, his observations and the information accompanying the Evaluation supported a finding by the Board that the management fees for each of the funds are reasonable and that Federated appeared to provide appropriate administrative services to the Fund for the fees paid. Under these circumstances, no changes were recommended to, and no objection was raised to, the continuation of the Fund's advisory and subadvisory contracts. The Board concluded that the nature, quality and scope of services provided the Fund by the Adviser and its affiliates were satisfactory.

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. 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 arrangements.

Notes to Financial Statements

January 31, 2012 (unaudited)

1. ORGANIZATION

Federated MDT Series (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 five portfolios. The financial statements included herein are only those of Federated MDT Large Cap Growth Fund (the “Fund”), a diversified portfolio. 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 offers four classes of shares: Class A Shares, Class B Shares, Class C Shares and Institutional Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is long-term capital appreciation.

2. SIGNIFICANT ACCOUNTING POLICIES

Investment Valuation

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

Equity securities listed on an exchange or traded through a regulated market system are valued at their last reported sale price or official closing price in their principal exchange or market.
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 Board of Trustees (the “Trustees”).
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 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), which approximates market value.
For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the purchase price of the security, information obtained by contacting the issuer, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded and public trading in similar securities of the issuer or comparable issuers.

Semi-Annual Shareholder Report

Table Of Contents

Fair Valuation and Significant Events Procedures

With respect to securities traded in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;
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.

Repurchase Agreements

Table Of Contents

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. Dividend income and distributions to shareholders are 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. Distributions of net investment income, if any, are declared and paid annually. Non-cash dividends included in dividend income, if any, are recorded at fair value. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that Class A Shares, Class B Shares, Class C Shares and Institutional Shares may bear distribution services fees, shareholder services fees and account administration fees unique to those classes. For the six months ended January 31, 2012, account administration fees for the Fund were as follows:

	Account Administration Fees Incurred
Class A Shares	$685

Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted using the effective interest rate method.

Federal Taxes

Table Of Contents

Fund recognizes interest and penalties, if any, related to tax liabilities as income tax expense in the Statement of Operations. As of January 31, 2012, tax years 2008 through 2011 remain subject to examination by the Fund's major tax jurisdictions, which include the United States of America and the Commonwealth of Massachusetts.

4. FEDERAL TAX INFORMATION

At January 31, 2012, the cost of investments for federal tax purposes was $54,309,219. The net unrealized appreciation of investments for federal tax purposes was $4,979,389. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $6,072,631 and net unrealized depreciation from investments for those securities having an excess of cost over value of $1,093,242.

At July 31, 2011, the Fund had a capital loss carryforward of $22,401,781 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, thereby reducing the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, a net capital loss incurred in taxable years beginning on or before December 22, 2010, is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010, retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

The following schedule summarizes the Fund's short-term and long-term capital loss carryforwards and expiration year:

Expiration Year	Short-Term	Long-Term	Total
2017	$20,801,154	NA	$20,801,154
2018	$1,600,627	NA	$1,600,627

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated MDTA LLC is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.75% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, the Adviser voluntarily waived $213,209 of its fee and voluntarily reimbursed $12,771 of other operating expenses.

Semi-Annual Shareholder Report

Table Of Contents

Administrative Fee

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
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 and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, FAS waived $27,365 of its fee. The net fee paid to FAS was 0.380% of average daily net assets of the Fund. The Fund is currently being charged the minimum administrative fee; therefore the fee as a percentage of average daily net assets is greater than the amounts presented in the chart above.

Distribution 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 daily net assets of the Fund's Class A Shares, Class B Shares and Class C Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at the following percentages of average daily net assets annually to compensate FSC:

Share Class Name	Percentage of Average Daily Net Assets of Class
Class A Shares	0.05%
Class B Shares	0.75%
Class C Shares	0.75%

	Distribution Services Fees Incurred
Class B Shares	$21,016

Table Of Contents

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in the three broad levels listed below:

Level 1 — quoted prices in active markets for identical securities, including investment companies with daily net asset values, if applicable.

Level 3 — significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

As of January 31, 2012, all investments of the Fund utilized Level 1 inputs in valuing the Fund's assets carried at fair value.

Notes to Financial Statements

January 31, 2012 (unaudited)

1. ORGANIZATION

Federated MDT Series (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 five portfolios. The financial statements included herein are only those of Federated MDT Small Cap Core Fund (the “Fund”), a diversified portfolio. 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 offers three classes of shares: Class A Shares, Class C Shares and Institutional Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is long-term capital appreciation.

2. SIGNIFICANT ACCOUNTING POLICIES

Investment Valuation

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

Equity securities listed on an exchange or traded through a regulated market system are valued at their last reported sale price or official closing price in their principal exchange or market.
Shares of other mutual funds are valued based upon their reported NAVs.
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), which approximates market value.
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.
For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the purchase price of the security, information obtained by contacting the issuer, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded and public trading in similar securities of the issuer or comparable issuers.

Semi-Annual Shareholder Report

Table Of Contents

Fair Valuation and Significant Events Procedures

With respect to securities traded in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;
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.

Repurchase Agreements

Table Of Contents

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. Dividend income and distributions to shareholders are 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. Distributions of net investment income, if any, are declared and paid annually. Non-cash dividends included in dividend income, if any, are recorded at fair value. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that Class A Shares, Class C Shares and Institutional Shares may bear distribution services fees and shareholder services fees unique to those classes. Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted using the effective interest rate method.

4. FEDERAL TAX INFORMATION

At January 31, 2012, the cost of investments for federal tax purposes was $9,281,062. The net unrealized appreciation of investments for federal tax purposes was $546,771. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $961,144 and net unrealized depreciation from investments for those securities having an excess of cost over value of $414,373.

Semi-Annual Shareholder Report

Table Of Contents

At July 31, 2011, the Fund had a capital loss carryforward of $11,736,991 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, thereby reducing the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, a net capital loss incurred in taxable years beginning on or before December 22, 2010, is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010 retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

The following schedule summarizes the Fund's short-term and long-term capital loss carryforwards and expiration year:

Expiration Year	Short-Term	Long-Term	Total
2016	$504,080	NA	$504,080
2017	$6,139,530	NA	$6,139,530
2018	$5,093,381	NA	$5,093,381

As a result of the tax-free transfer of assets from Federated MDT Small Cap Value Fund, the use of certain capital loss carryforwards listed above may be limited.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated MDTA LLC is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 1.15% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee and/or reimburse certain operating expenses of the Fund. For the six months ended January 31, 2012, the Adviser voluntarily waived $53,555 of its fee and voluntarily reimbursed $156,851 of other operating expenses.

Administrative Fee

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
0.075%	on assets in excess of $20 billion

Semi-Annual Shareholder Report

Table Of Contents

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, FAS waived $22,576 of its fee. The net fee paid to FAS was 1.995% of average daily net assets of the Fund. The Fund is currently being charged the minimum administrative fee; therefore the fee as a percentage of average daily net assets is greater than the amounts presented in the chart above.

Distribution 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 daily net assets of the Fund's Class A and Class C Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at the following percentages of average daily net assets annually, to compensate FSC:

Share Class Name	Percentage of Average Daily Net Assets of Class
Class A Shares	0.05%
Class C Shares	0.75%

	Distribution Services Fees Incurred
Class C Shares	$9,194

When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the six months ended January 31, 2012, FSC retained $972 of fees paid by the Fund. For the six months ended January 31, 2012, the Fund's Class A Shares did not incur a distribution services fee; however, it may begin to incur this fee upon approval of the Trustees.

Sales Charges

Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. For the six months ended January 31, 2012, FSC retained $634 in sales charges from the sale of Class A Shares.

Semi-Annual Shareholder Report

Table Of Contents

Notes to Financial Statements

January 31, 2012 (unaudited)

1. ORGANIZATION

Federated MDT Series (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 five portfolios. The financial statements included herein are only those of Federated MDT Small Cap Growth Fund (the “Fund”), a diversified portfolio. 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 offers four classes of shares: Class A Shares, Class B Shares, Class C Shares and Institutional Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is to provide long-term capital appreciation.

2. SIGNIFICANT ACCOUNTING POLICIES

Investment Valuation

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

Equity securities listed on an exchange or traded through a regulated market system are valued at their last reported sale price or official closing price in their principal exchange or market.
Shares of other mutual funds are valued based upon their reported NAVs.
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 Fund's 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), which approximates market value.
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.
For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the purchase price of the security, information obtained by contacting the issuer, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded and public trading in similar securities of the issuer or comparable issuers.

Fair Valuation and Significant Events Procedures

With respect to securities traded in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;
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.

Repurchase Agreements

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. Dividend income and distributions to shareholders are 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. Distributions of net investment income, if any, are declared and paid annually. Non-cash dividends included in dividend income, if any, are recorded at fair value. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that Class A Shares, Class B Shares, Class C Shares and Institutional Shares may bear distribution services fees, shareholder services fees and account administration fees unique to those classes. For the six months ended January 31, 2012, account administration fees for the Fund were as follows:

	Account Administration Fees Incurred
Class A Shares	$132
Class C Shares	243
TOTAL	$375

Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

4. FEDERAL TAX INFORMATION

At January 31, 2012, the cost of investments for federal tax purposes was $52,429,293. The net unrealized appreciation of investments for federal tax purposes was $6,088,808. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $8,360,125 and net unrealized depreciation from investments for those securities having an excess of cost over value of $2,271,317.

At July 31, 2011, the Fund had a capital loss carryforward of $28,777,412 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, thereby reducing the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, a net capital loss incurred in taxable years beginning on or before December 22, 2010 is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010 retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

The following schedule summarizes the Fund's short-term and long-term capital loss carryforwards and expiration year:

Expiration Year	Short-term	Long-term	Total
2017	$3,319,329	NA	$3,319,329
2018	$25,458,083	NA	$25,458,083

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated MDTA LLC is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 1.15% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, the Adviser voluntarily waived $307,732 of its fee.

Administrative Fee

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
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 and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the six months ended January 31, 2012, FAS waived $27,378 of its fee. The net fee paid to FAS was 0.398% of average daily net assets of the Fund. The Fund is currently being charged the minimum administrative fee; therefore the fee as a percentage of average daily net assets is greater than the amounts presented in the chart above.

Distribution 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 daily net assets of the Fund's Class A Shares, Class B Shares and Class C Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at the following percentages of average daily net assets annually, to compensate FSC:

Share Class Name	Percentage of Average Daily Net Assets of Class
Class A Shares	0.05%
Class B Shares	0.75%
Class C Shares	0.75%

The Board also received financial information about Federated, including information regarding the compensation and benefits Federated derived from its relationships with the Federated funds. This information covered 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 information also detailed 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 waived fees and/or reimbursed 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 reporting as to the institution or elimination of these voluntary waivers.
