Management's Discussion of Fund Performance (unaudited)

The total return of Federated MDT All Cap Core Fund (the “Fund”), based on net asset value, for the 12-month reporting period ended July 31, 2018, was 20.78% for Class A Shares, 19.91% for Class C Shares, 21.15% for Institutional Shares and 21.17% for Class R6 Shares. The total return for the Russell 3000^® Index (R3000),¹ the Fund's broad-based securities market index, was 16.39% for the same period. The total return of the Morningstar Large Blend Funds Average (MLBFA),² a peer group average for the Fund, was 14.60% during the same period. The Fund's and MLBFA's total returns for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the R3000.

During the reporting period, the Fund's investment strategy focused on stock selection. This was the most significant factor affecting the Fund's performance relative to the R3000 during the period.

The following discussion will focus on the performance of the Fund's Class R6 Shares.

Market Overview

During the reporting period, overall domestic equity market performance was strong as evidenced by the 16.39% return of the whole-market R3000. On average, very small-cap stocks³ had the best year, followed by very large-cap stocks: the Russell Microcap^® Index⁴ returned 20.80%, the small-cap Russell 2000^® Index⁵ returned 18.73%, and the Russell Top 200^® Index⁶ returned 17.28%. Mid-cap stocks trailed for the year with the Russell Midcap^® Index⁷ returning 13.45%. For style, growth led value by a substantial margin in August 2017, October 2017, January 2018, February 2018, and May 2018. While there were some months that did favor value slightly, they did little to offset the cumulative difference: for the year, the Russell 3000^® Growth Index⁸ returned 22.86%, and the Russell 3000^® Value Index⁹ returned 9.91%.

The best performing sectors in the R3000 during the reporting period were Information Technology (27.94%), Consumer Discretionary (21.61%) and Energy (20.71%). Underperforming sectors during the same period included Telecommunication Services (-2.46%), Consumer Staples (0.11%) and Utilities (4.02%).

Annual Shareholder Report

STOCK SELECTION

When looking at the Fund's outperformance in terms of fundamental and technical characteristics during this growth-oriented period, most of the Fund's outperformance relative to the R3000 was driven by growth-oriented stocks with high analyst conviction. More value-oriented stock picks were, overall, neutral when compared to the benchmark. The Fund's sector exposures remained close to R3000 weights; at the end of the fiscal year there was an underweight in the Real Estate sector (the Fund does not invest in the Real Estate sector) and no significant overweights. Strong stock selection in the Health Care, Consumer Staples and Energy sectors contributed the most to the Fund's outperformance. There was a small offset from the Utilities sector.

Individual stocks enhancing the Fund's performance during the reporting period included Align Technology, Mastercard Incorporated, ConocoPhillips and AutoZone.

Individual stocks detracting from the Fund's performance during the reporting period included Amazon.com, Inc., Microsoft and Alphabet Inc., which were not held by the Fund but outperformed the R3000. There was a small offset from Celgene Corporation, which was overweighted.

1	Please see the footnotes to the line graphs below for definitions of, and further information about, the Russell 3000^® Index.
2	Morningstar has assigned the Fund to the Morningstar Large Cap Value Funds Average peer group, however, the MLBFA is being used for comparison purposes. The Fund invests in both value and growth stocks and therefore the Fund's Adviser believes that the MLBFA is more reflective of the Fund's investment style. Please see the footnotes to the line graphs below for definitions of, and further information about, the MLBFA.
3	Small-cap stocks may be less liquid and subject to greater price volatility than large-cap stocks.
4	The Russell Microcap^® Index measures the performance of the microcap segment of the U.S. equity market. Microcap stocks make up less than 3% of the U.S. equity market (by market cap) and consist of the smallest 1,000 securities in the small-cap Russell 2000^® Index, plus the next 1,000 smallest eligible securities by market cap. The Russell Microcap^® Index is constructed to provide a comprehensive and unbiased barometer for the microcap segment trading on national exchanges and is completely reconstituted annually to ensure new and growing equities are reflected and companies continue to reflect appropriate capitalization and value characteristics.*
5	The Russell 2000^® Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000^® Index is a subset of the Russell 3000^® Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2000 of the smallest securities based on a combination of their market cap and current index membership. The Russell 2000^® Index is constructed to provide a comprehensive and unbiased small-cap barometer and is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small-cap opportunity set.*

6	The Russell Top 200^® Index measures the performance of the largest cap segment of the U.S. equity universe. The Russell Top 200^® Index is a subset of the Russell 3000^® Index. It includes approximately 200 of the largest securities based on a combination of their market cap and current index membership and represents approximately 68% of the U.S. market. The Russell Top 200^® Index is constructed to provide a comprehensive and unbiased barometer for this very large cap segment and is completely reconstituted annually to ensure new and growing equities are reflected.*
7	The Russell Midcap^® Index measures the performance of the mid-cap segment of the U.S. equity universe. The Russell Midcap^® Index is a subset of the Russell 1000^® Index. It includes approximately 800 of the smallest securities based on a combination of their market cap and current index membership. The Russell Midcap^® Index represents approximately 31% of the total market capitalization of the Russell 1000^® companies. The Russell Midcap^® Index is constructed to provide a comprehensive and unbiased barometer for the mid-cap segment. The Russell Midcap Index is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true mid-cap opportunity set.*
8	The Russell 3000^® Growth Index measures the performance of the broad growth segment of the U.S. equity universe. It includes those Russell 3000^® Index companies with higher price-to-book ratios and higher forecasted growth values. The Russell 3000^® Growth Index is constructed to provide a comprehensive, unbiased and stable barometer of the broad growth market. The Russell 3000 Growth Index is completely reconstituted annually to ensure new and growing equities are included and that the represented companies continue to reflect growth characteristics.*
9	The Russell 3000^® Value Index measures the performance of the broad value segment of U.S. equity value universe. It includes those Russell 3000^® Index companies with lower price-to-book ratios and lower forecasted growth values. The Russell 3000^® Value Index is constructed to provide a comprehensive, unbiased and stable barometer of the broad value market. The Russell 3000 Value Index is completely reconstituted annually to ensure new and growing equities are included and that the represented companies continue to reflect value characteristics.*
*	The index is unmanaged, and it is not possible to invest directly in an index.

FUND PERFORMANCE AND GROWTH OF A $10,000 INVESTMENT

The graph below illustrates the hypothetical investment of $10,000¹ in the Federated MDT All Cap Core Fund (the “Fund”) from July 31, 2008 to July 31, 2018, compared to the Russell 3000^®Index (R3000)²and the Morningstar Large Blend Funds Average (MLBFA).³ The Average Annual Total Return table below shows returns for each class averaged over the stated periods.

Growth of a $10,000 Investment

Growth of $10,000 as of July 31, 2018

■	Total returns shown for the Class C Shares include the maximum contingent deferred sales charge of 1.00% as applicable.

The Fund offers multiple share classes whose performance may be greater than or less than its other share class(es) due to differences in sales charges and expenses. See the Average Annual Total Return table below for the returns of additional classes not shown in the line graph above.

Average Annual Total Returnsfor the Period Ended 7/31/2018

(returns reflect all applicable sales charges and contingent deferred sales charges as specified below in footnote #1)

	1 Year	5 Years	10 Years
Class A Shares	14.15%	11.06%	7.80%
Class C Shares	18.91%	11.46%	7.57%
Institutional Shares	21.15%	12.65%	8.72%
Class R6 Shares⁴	21.17%	12.14%	8.06%

MLBFA	14.60%	11.39%	9.60%

Annual Shareholder Report

Performance data quoted represents past performance which is no guarantee of future results. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Mutual fund performance changes over time and current performance may be lower or higher than what is stated. For current to the most recent month-end performance and after-tax returns, visit FederatedInvestors.com or call 1-800-341-7400. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Mutual funds are not obligations of or guaranteed by any bank and are not federally insured.

1	Represents a hypothetical investment of $10,000 in the Fund after deducting applicable sales charges: for Class A Shares, the maximum sales charge of 5.50% ($10,000 investment minus $550 sales charge = $9,450); for Class C Shares a 1.00% contingent deferred sales charge would be applied on any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The R3000 and MLBFA have been adjusted to reflect reinvestment of dividends of securities.
2	The R3000 measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market. The R3000 is constructed to provide a comprehensive, unbiased, and stable barometer of the broad market and is completely reconstituted annually to ensure new and growing equities are reflected. The index is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The R3000 is not adjusted to reflect sales charges, expenses or other fees that the Securities and Exchange Commission requires to be reflected in the Fund's performance.
3	Morningstar figures represent the average of the total returns reported by all the funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges. The Morningstar figures in the Growth of $10,000 line graph are based on historical return information published by Morningstar and reflect the return of the funds comprising the category in the year of publication. Because the funds designated by Morningstar as falling into the category can change over time, the Morningstar figures in the line graph may not match the Morningstar figures in the Average Annual Total Returns table, which reflect the return of the funds that currently comprise the category.
4	Prior to September 1, 2016, Class R6 Shares were known as Class R Shares and included 12b-1 fees and certain other expenses. As of September 1, 2016, Class R6 does not include such 12b-1 fees and certain other expenses, and the performance shown above for Class R6 prior to September 1, 2016, reflects the higher Class R expenses.

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.

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 July 31, 2018, all investments of the Fund utilized Level 1 inputs in valuing the Fund's assets carried at fair value.

Notes to Financial Statements

July 31, 2018

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, Institutional Shares and Class R6 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.

Prior to their re-designation on September 1, 2016, Class R6 Shares were Class R Shares.

On March 30, 2017, the Fund's T Share class became effective with the Securities and Exchange Commission (SEC), but is not yet offered for sale.

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 or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Fixed-income securities are fair valued using price evaluations provided by a pricing service approved by the Fund's Board of Trustees (the “Trustees”).
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	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 last traded or purchase price of the security, information obtained by contacting the issuer or dealers, 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, public trading in similar securities or derivative contracts of the issuer or comparable issuers, movement of a relevant index, or other factors including but not limited to industry changes and relevant government actions.

Annual Shareholder Report

in the opinion of the valuation committee (“Valuation Committee”), is deemed not representative of the fair value of such security, 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 obtain the fair value assigned to an investment if it sold the investment at approximately the time at which the Fund determines its NAV per share.

Fair Valuation Procedures

The Trustees have ultimate responsibility for determining the fair value of investments for which market quotations are not readily available. The Trustees have appointed a Valuation Committee comprised of officers of the Fund, Federated MDTA LLC (the “Adviser”) and certain of the Adviser's affiliated companies to assist in determining fair value and in overseeing the calculation of the NAV. The Trustees have also authorized the use of pricing services recommended by the Valuation Committee to provide fair value evaluations of the current value of certain investments for purposes of calculating the NAV. The Valuation Committee employs various methods for reviewing third-party pricing-service evaluations including periodic reviews of third-party pricing services' policies, procedures and valuation methods (including key inputs, methods, models and assumptions), transactional back-testing, comparisons of evaluations of different pricing services, and review of price challenges by the Adviser based on recent market activity. In the event that market quotations and price evaluations are not available for an investment, the Valuation Committee determines the fair value of the investment in accordance with procedures adopted by the Trustees. The Trustees periodically review and approve the fair valuations made by the Valuation Committee and any changes made to the procedures.

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 any U.S. Treasury and Agency securities, mortgage-backed securities and municipal securities. The Fund normally uses mid evaluations for any other types of fixed-income securities and any 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.

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.

Annual Shareholder Report

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 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. Amortization/accretion of premium and discount is included in investment income. 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 select classes will bear certain expenses unique to those classes. The detail of the total fund expense reimbursement of $2,387 is disclosed in Note 5. For the year ended July 31, 2018, transfer agent fees for the Fund were as follows:

	Transfer Agent Fees Incurred
Class A Shares	$43,029
Class C Shares	37,877
Institutional Shares	46,243
Class R6 Shares	6,360
TOTAL	$133,509

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.

Annual Shareholder Report

Other Service Fees

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Class A Shares and Class C Shares to unaffiliated financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. For the year ended July 31, 2018, other service fees for the Fund were as follows:

	Other Service Fees Incurred
Class A Shares	$91,070
Class C Shares	94,462
TOTAL	$185,532

Federal Taxes

It is the Fund's policy to comply with the Subchapter M provision of the Internal Revenue Code and to distribute to shareholders each year substantially all of its income. Accordingly, no provision for federal income tax is necessary. As of and during the year ended July 31, 2018, 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 July 31, 2018, tax years 2015 through 2018 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.

Securities Lending

The Fund participates in a securities lending program providing for the lending of equity securities to qualified brokers. The term of the loans within the program is one year or less. The Fund normally receives cash collateral for securities loaned that may be invested in affiliated money market funds, other money market instruments and/or repurchase agreements. Investments in money market funds may include funds with a “floating” NAV that can impose redemption fees and liquidity gates, impose certain operational impediments to investing cash collateral, and, if the investee fund's NAV decreases, result in the Fund recognizing losses and being required to cover the decrease in the value of the cash collateral. Collateral is maintained at a minimum level of 100% of the market value of investments loaned, plus interest, if applicable. In accordance with the Fund's securities lending agreement, the market value of securities on loan is determined each day at the close of business and any

Annual Shareholder Report

additional collateral required to cover the value of securities on loan is delivered to the Fund on the next business day. Earnings on collateral are allocated between the borrower of the security, the securities lending agent, as a fee for its services under the program and the Fund, according to agreed-upon rates.

Securities lending transactions are subject to Master Netting Agreements which are agreements between the Fund and its counterparties that provide for the net settlement of all transactions and collateral with the Fund, through a single payment, in the event of default or termination. Amounts presented on the Portfolio of Investments and Statement of Assets and Liabilities are not net settlement amounts but gross. As indicated below, the cash collateral received by the Fund exceeds the market value of the securities loaned reducing the net settlement amount to zero. The chart below identifies the amount of collateral received as well as the market value of securities on loan. Additionally, the securities lending agreement executed by the Fund includes an indemnification clause. This clause stipulates that the borrower will reimburse the Fund for any losses as a result of any failure of the borrower to return equivalent securities to the Fund.

As of July 31, 2018, securities subject to this type of arrangement and related collateral were as follows:

Market Value of Securities Loaned	Market Value of Collateral
$704,703	$740,143

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. The Fund applies investment company accounting and reporting guidance.

4. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due to differing treatments for expiration of capital loss carryforwards, regulatory settlement proceeds and return of capital adjustments.

For the year ended July 31, 2018, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Paid-In Capital	Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)
$(37,254,849)	$(77,601)	$37,332,450

Net investment income (loss), net realized gains (losses), and net assets were not affected by this reclassification.

Annual Shareholder Report

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended July 31, 2018 and 2017, was as follows:

	2018	2017
Ordinary income	$643,895	$1,100,878

As of July 31, 2018, the components of distributable earnings on a tax-basis were as follows:

Undistributed ordinary income	$163,254
Net unrealized appreciation	$19,568,956

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for deferral of losses on wash sales and non-taxable dividends.

At July 31, 2018, the cost of investments for federal tax purposes was $176,640,156. The net unrealized appreciation of investments for federal tax purposes was $19,568,956. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $27,200,101 and net unrealized depreciation from investments for those securities having an excess of cost over value of $7,631,145.

The Fund used capital loss carryforwards of $17,335,786 to offset capital gains realized during the year ended July 31, 2018.

Capital loss carryforwards of $37,253,961 expired during the year ended July 31, 2018.

Other Service Fees

For the year ended July 31, 2018, FSSC received $4,036 of the other service fees disclosed in Note 2.

Sales Charges

Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund.

7. LINE OF CREDIT

The Fund participates with certain other Federated Funds, on a several basis, in an up to $500,000,000 unsecured, 364-day, committed, revolving line of credit (LOC) agreement. The LOC was made available to finance temporarily the repurchase or redemption of shares of the Fund, failed trades, payment of dividends, settlement of trades and for other short-term, temporary or emergency general business purposes. The Fund cannot borrow under the LOC if an inter-fund loan is outstanding. The Fund's ability to borrow under the LOC also is subject to the limitations of the Act and various conditions precedent that must be satisfied before the Fund can borrow. Loans under the LOC are charged interest at a fluctuating rate per annum equal to the highest, on any day, of (a) (i) the federal funds effective rate, (ii) the one month London Interbank Offered Rate (LIBOR), and (iii) 0.0%, plus (b) a margin. The LOC also requires the Fund to pay, quarterly in arrears and at maturity, its pro rata share of a commitment fee based on the amount of the lenders' commitment that has not been utilized. As of July 31, 2018, the Fund had no outstanding loans. During the year ended July 31, 2018, the Fund did not utilize the LOC.

8. INTERFUND LENDING

Report of Independent Registered Public Accounting Firm

TO THE BOARD OF TRUSTEES OF FEDERATED MDT SERIES AND SHAREHOLDERS OF FEDERATED MDT ALL CAP CORE FUND:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Federated MDT All Cap Core Fund (the “Fund”) (one of the portfolios constituting Federated MDT Series), including the portfolio of investments, as of July 31, 2018, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund at July 31, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund's internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of July 31, 2018, by correspondence with the custodian and others, or by other appropriate auditing procedures where replies from others were not received. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall

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 other service 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 February 1, 2018 to July 31, 2018.

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.

Annual Shareholder Report

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 2/1/2018	Ending Account Value 7/31/2018	Expenses Paid During Period¹
Actual:
Class A Shares	$1,000	$1,028.40	$6.79
Class C Shares	$1,000	$1,024.90	$10.39
Institutional Shares	$1,000	$1,030.20	$5.29
Class R6 Shares	$1,000	$1,030.30	$5.08
Hypothetical (assuming a 5% return before expenses):
Class A Shares	$1,000	$1,018.10	$6.76
Class C Shares	$1,000	$1,014.50	$10.34
Institutional Shares	$1,000	$1,019.60	$5.26
Class R6 Shares	$1,000	$1,019.80	$5.06

1	Expenses are equal to the Fund's annualized net expense ratios, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half-year period). The annualized net expense ratios are as follows:

Class A Shares	1.35%
Class C Shares	2.07%
Institutional Shares	1.05%
Class R6 Shares	1.01%

Annual Shareholder Report

Evaluation and Approval of Advisory Contract–May 2018

Federated MDT All Cap Core Fund (the “Fund”)

At its meetings in May 2018, the Fund's Board of Trustees (the “Board”), including a majority of those Trustees who are not “interested persons” of the Fund, as defined in the Investment Company Act of 1940 (the “Independent Trustees”) reviewed and unanimously approved the continuation of the Fund's investment advisory contract for an additional one-year term. The Board's decision regarding the contract reflects the exercise of its business judgment after considering all of the information received on whether to continue the existing arrangements.

The Board had previously appointed a Senior Officer, whose duties included specified responsibilities relating to the process by which advisory fees are to be charged to a fund advised by Federated MDTA LLC (the “Adviser”) or its affiliates (collectively, “Federated”) (each, a “Federated fund”). The Senior Officer's responsibilities included preparation and furnishing to the Board an annual independent written evaluation that covered topics discussed below. In December 2017, the Senior Officer position was eliminated. Notwithstanding the elimination of the Senior Officer position, at the request of the Independent Trustees, the Fund's Chief Compliance Officer (the CCO) furnished to the Board in advance of its May 2018 meetings an independent written evaluation covering substantially the same topics that had been covered in the Senior Officer's written evaluation in prior years. The Board considered the CCO's independent written evaluation (the “CCO Fee Evaluation Report”), along with other information, in evaluating the reasonableness of the Fund's management fee and in deciding to approve the continuation of the investment advisory contract. Consistent with the former Senior Officer position, the CCO, in preparing the CCO Fee Evaluation Report, has the authority to retain consultants, experts or staff as reasonably necessary to assist in the performance of his duties, reports directly to the Board, and can be terminated only with the approval of a majority of the Independent Trustees.

The Board also considered judicial decisions concerning allegedly excessive investment advisory fees in making its decision. Using these judicial decisions as a guide, the Board observed that the following factors may be relevant to an adviser's fiduciary duty with respect to its receipt of compensation from a fund: (1) the nature and quality of the services provided by an adviser to a fund and its shareholders (including the performance of the fund, its benchmark, and comparable funds); (2) an adviser's cost of providing the services (including the profitability to an adviser of providing advisory services to a fund); (3) the extent to which an adviser may realize “economies of scale” as a fund grows larger and, if such economies of scale exist, whether they have been shared with a fund and its shareholders or the family of funds; (4) any “fall-out” financial benefits that accrue to an adviser because of its relationship with a fund (including

Annual Shareholder Report

research services received from brokers that execute fund trades and any fees paid to affiliates of an adviser for services rendered to a fund); (5) comparative fee and expense structures (including a comparison of fees paid to an adviser with those paid by similar funds both internally and externally as well as management fees charged to institutional and other advisory clients of the Adviser or its affiliates for what might be viewed as like services); and (6) the extent of care, conscientiousness and independence with which the fund's board members perform their duties and their expertise (including whether they are fully informed about all facts the board deems relevant to its consideration of an adviser's services and fees). The Board noted that the Securities and Exchange Commission (SEC) disclosure requirements regarding the basis for the Board's approval of the Fund's investment advisory contract generally align with the factors listed above. The Board was aware of these factors and was guided by them in its review of the Fund's investment advisory contract to the extent it considered them to be appropriate and relevant, as discussed further below.

The Board considered and weighed these factors in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to the Federated funds. The Independent Trustees were assisted in their deliberations by independent legal counsel.

In addition to the extensive materials that comprise and accompany the CCO Fee Evaluation Report, the Board received detailed information about the Fund and the Federated organization throughout the year, and in connection with its May meetings at which the Board's formal approval of the advisory and subadvisory contracts occurred. In this regard, Federated provided much of this information at each regular meeting of the Board, and furnished additional information specifically in connection with the May meetings. In the months preceding the May meetings, the Board requested and reviewed written materials prepared by Federated in response to requests on behalf of the Independent Trustees encompassing a wide variety of topics. At the May meetings, in addition to meeting in separate sessions of the Independent Trustees without management present, senior management of the Adviser also met with the Independent Trustees and their counsel to discuss the materials presented and such additional matters as the Independent Trustees deemed reasonably necessary to evaluate the advisory and subadvisory contracts. Between regularly scheduled meetings, the Board also received information on particular matters as the need arose.

The Board's consideration of the investment advisory contract included review of the CCO's Fee Evaluation Report, accompanying data and additional information covering the following matters, among others: the Adviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short-term and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in terms relative to its particular investment program and certain competitor or “peer group” funds and/or other benchmarks, as appropriate) and comments on the

Annual Shareholder Report

reasons for performance; the Fund's investment objectives; the Fund's expenses, including the advisory fee 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; the entrepreneurial and other risks assumed by the Adviser in sponsoring the Fund; 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 funds which include a comprehensive array of funds with different investment objectives, policies and strategies which are generally 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.

While mindful that courts have cautioned against giving too much weight to comparative information concerning fees charged by other advisers for managing funds with comparable investment programs, the Board has found the use of such comparisons to be relevant to its deliberations. In this regard, the Board was presented with, and considered, information regarding the contractual advisory fee rates, net advisory fee rates, total expense ratios and each element of the Fund's total expense ratio (i.e., gross and net advisory fees, custody fees, portfolio accounting fees and transfer agency fees) relative to an appropriate group of peer funds compiled by Federated using data supplied by independent fund ranking organizations (the “Peer Group”). The Board received a description of the composition and methodology used to select the Peer Group. 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, in that they are readily available to Fund shareholders as alternative investment vehicles. Also, 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 relevant indicator of what consumers have found to be reasonable in the marketplace in which the Fund competes.

Annual Shareholder Report

The Board reviewed the contractual advisory fee rate and other expenses of the Fund and noted the position of the Fund's fee rates relative to its Peer Group. In this regard, the Board noted that the contractual advisory fee rate was above the median of the relevant Peer Group, but the Board noted the applicable waivers and reimbursements and that the overall expense structure of the Fund remained competitive in the context of other factors considered by the Board. In this regard, the Board had been previously advised that, while comparisons to fund Peer Groups are relevant in judging the reasonableness of advisory fees, the Fund's quantitative focus makes fee and expense comparisons particularly difficult. Although the Fund's advisory fee was above the median of the peer range, the Peer Group of funds varied widely in their complexity, and the Board has been informed that the management of the Fund is among the more complex relative to its Peer Group.

For comparison, the CCO reviewed the fees charged by Federated for providing advisory services to products other than the Federated funds (e.g., institutional and separate accounts and third-party unaffiliated mutual funds for which Federated serves as sub-adviser) (referenced to as “Comparable Funds/Accounts”). With respect to Comparable Funds/Accounts other than third-party mutual funds, the CCO concluded that they are inherently different products. Those differences include, but are not limited to, different types of targeted investors; different applicable laws and regulations; different legal structures; different average account sizes and portfolio management techniques made necessary by different cash flows and different associated costs; and the time spent by portfolio managers and their teams, as well as personnel in the Funds Financial Services, Legal, Compliance and Risk Management departments, in reviewing securities pricing, addressing different administrative responsibilities, addressing different degrees of risk associated with management and a variety of different costs. The CCO also reviewed the differences in the nature of the services required for Federated to manage its proprietary mutual fund business versus managing a discrete pool of assets as a sub-adviser to another institution's mutual fund, and that Federated generally performs significant additional services and assumes substantially greater risk in managing the Fund and other Federated funds than in its role as sub-adviser to an unaffiliated third-party mutual fund. The CCO did not consider the fees for providing advisory services to Comparable Funds/Accounts to be determinative in judging the appropriateness of the Federated funds' advisory fees.

The CCO noted that the services, administrative responsibilities and risks associated with such relationships are quite different than serving as a primary adviser to a fund.

Following such evaluation, and full deliberations, the Board concluded that the fees and expenses of the Fund are reasonable and supported renewal of the Fund's investment advisory contract.

Annual Shareholder Report

The Board considered the nature, extent and quality of the services provided to the Fund by the Adviser and the resources of the Adviser and its affiliates dedicated to the Fund. In this regard, the Board evaluated, among other things, the Adviser's personnel, experience, track record, overall reputation and willingness to invest in personnel and infrastructure that benefit the Fund. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day management of the Fund and the Adviser's ability and experience in attracting and retaining qualified personnel to service the Fund. The Board noted the compliance program of the Adviser and the compliance-related resources provided to the Fund by the Adviser, including the Adviser's commitment to respond to rulemaking initiatives of the SEC. The Fund's ability to deliver competitive performance when compared to its Peer Group was also deemed to be relevant by the Board as a useful indicator of how the Adviser is executing the Fund's investment program. The Adviser's ability to execute this program was one of the Board's considerations in reaching a conclusion that the nature, extent and quality of the Adviser's investment management services warrant the continuation of the investment advisory contract.

In evaluating the Fund's investment performance, the Board considered performance results in light of the Fund's investment objective, strategies and risks, as disclosed in the Fund's prospectus. The Board considered detailed investment reports on the Fund's performance that were provided to the Board throughout the year and in connection with the May meetings. The CCO also reviewed information regarding the performance of other mutual funds in the Peer Group, noting the CCO's view that comparisons to fund peer groups may be helpful, though not conclusive, in evaluating the performance of the Adviser in managing the Fund. The Board considered, in evaluating such comparisons, that in some cases individual funds may exhibit significant and unique differences in their objectives and management techniques when compared to other funds within a Peer Group, and that the CCO had specifically noted that the Fund's quantitative focus makes fee and expense comparisons particularly difficult as the Peer Group of funds varied widely in their complexity, and the management of the Fund is among the more complex relative to its Peer Group.

For the one-year, three-year and five-year periods covered by the CCO Fee Evaluation Report, the Fund's performance was above the median of the relevant Peer Group. In addition, the Board was informed by the Adviser that, for the same periods, the Fund outperformed its benchmark index for the five-year period and underperformed its benchmark index for the one-year and three-year periods.

Following such evaluation, and full deliberations, the Board concluded that the performance of the Fund supported renewal of the Fund's advisory contract.

Annual Shareholder Report

The Board also received financial information about Federated, including information regarding the compensation and ancillary (or “fall-out”) benefits Federated derived from its relationships with the Federated funds. This information covered not only the fees under the investment 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 and distributor). In this regard, the Board considered that certain Federated subsidiaries provide distribution and shareholder services to the Federated funds, for which they may be compensated through distribution and servicing fees paid pursuant to Rule 12b-1 plans or otherwise. 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 Federated fund to be competitive in the marketplace, the Adviser and its affiliates frequently waived fees and/or reimbursed expenses and have disclosed to Federated fund investors and/or indicated to the Board their intention to do so in the future. Moreover, the Board receives regular reporting as to the institution, adjustment or elimination of these voluntary waivers. The Board considered Federated's previous reductions in contractual management fees to certain Federated funds in response to the CCO's recommendations.

Federated furnished information, requested by the CCO, 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 CCO. The CCO noted that, while these cost allocation reports apply consistent allocation processes, the inherent difficulties in allocating costs continues to cause the CCO to question the precision of the process and to conclude that such reports may be unreliable, since a single change in an allocation estimate may dramatically alter the resulting estimate of cost and/or profitability of a Federated fund and may produce unintended consequences. The allocation information, including the CCO's view that fund-by-fund estimations may be unreliable, was considered in the evaluation by the Board.

The Board and the CCO also reviewed information compiled by Federated comparing its profitability information to other publicly held fund management companies, including information regarding profitability trends over time. In this regard, the CCO concluded that Federated's profit margins did not appear to be excessive. The CCO also noted that Federated appeared financially sound, with the resources necessary to fulfill its obligations under its contracts with the Fund.

Annual Shareholder Report

(including technology relating to cybersecurity) and that the benefits of these efforts (as well as any economies of scale, should they exist) were likely to be shared with the Federated fund family as a whole. The Board noted that the Adviser's investments in these areas are extensive. In addition, the Board considered that the Adviser and its affiliates have frequently waived fees and/or reimbursed expenses and that this has allowed fund shareholders to share potential economies of scale with shareholders. The Board also considered that such waivers and reimbursements can provide protection from an increase in expenses if a Federated fund's assets decline. Federated, as it does throughout the year, and specifically in connection with the Board's review of the advisory and subadvisory contracts, furnished information relative to revenue sharing or adviser-paid fees. Federated and the CCO noted that this information should be viewed to determine if there was an incentive to either not apply breakpoints, or to apply breakpoints at higher levels, and should not be viewed to determine the appropriateness of advisory fees because it would represent marketing and distribution expenses. The Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the CCO Fee Evaluation Report) 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 a fund attains a certain size.

The CCO stated that his observations and the information accompanying the CCO Fee Evaluation Report supported a finding by the Board that the management fee for the Fund was reasonable. Under these circumstances, no changes were recommended to, and no objection was raised to the continuation of, the Fund's investment advisory contract. The CCO also recognized that the Board's evaluation of the Federated funds' advisory and subadvisory arrangements is a continuing and on-going process that is informed by the information that the Board requests and receives from management throughout the course of the year and, in this regard, the CCO noted certain items for future reporting to the Board or further consideration by management as the Board continues its on-going oversight of the Federated funds.

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 investment 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 investment advisory contract reflected the fact that it is the shareholders who have effectively selected the Adviser by virtue of

Annual Shareholder Report

having invested in the Fund. The Board concluded that, in light of the factors summarized above, including the nature, quality and scope of the services provided to the Fund by the Adviser and its affiliates, continuation of the investment advisory contract was appropriate.

The Board based its decision to approve the investment 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 continuation of the contract reflects its view that Federated's performance and actions provided a satisfactory basis to support the decision to continue the existing arrangement.

Management's Discussion of Fund Performance (unaudited)

Federated MDT Balanced Fund's (the “Fund”) total return, based on net asset value, for the 12-month reporting period ended July 31, 2018, was 11.91% for Class A Shares, 11.09% for Class C Shares, 12.15% for Institutional Shares and 12.24% for Class R6 Shares. Over the same period, the Fund's custom blended benchmark (“Blended Index”),¹ which consists of a 60%/40% blend of the Standard & Poor's 500 Index(S&P 500)² and the Bloomberg Barclays U.S. Aggregate Bond Index (BAB),³ returned 9.23%. The total return of the Morningstar US Allocation 50% - 70% Equity Category Average (MA50-70),⁴ a peer group average for the Fund, was 7.08% during the period. The Fund's and the MA50-70's total return for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the Blended Index.

During the reporting period, the Fund's investment strategy focused on security selection within the equity segment of the portfolio, asset allocation, and duration positioning within the fixed-income segment of the portfolio. These were the most significant factors affecting the Fund's performance relative to the Blended Index during the period.

The following discussion will focus on the performance of the Fund's Class R6 Shares.

MArket Overview

During the reporting period, overall domestic equity market performance was strong as evidenced by the 16.39% return on the whole-market Russell 3000^® Index (R3000).⁵ On average, very small-cap stocks⁶ had the best year, followed by very large-cap stocks: the Russell Microcap^® Index⁷ returned 20.80%, the small-cap Russell 2000^® Index⁸ returned 18.73%, and the Russell Top 200^® Index⁹ returned 17.28%. Mid-cap stocks trailed for the year with the Russell Midcap^® Index¹⁰ returning 13.45%. In terms of style, growth led value by a substantial margin with the Russell 3000^® Growth Index¹¹ returning 22.86% and the Russell 3000^® Value Index¹² 9.91% for the year.

The best performing sectors in the R3000 during the reporting period were Information Technology (27.94%) Consumer Discretionary (21.61%) and Energy (20.71%), while the most significant underperforming sectors were Telecom Services (-2.46%) and Consumer Staples (0.11%).

International equities¹³ in developed markets underperformed the domestic equity market during the reporting period with the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index¹⁴ returning 6.40%. Emerging market¹⁵ equities performance was even weaker, with the MSCI Emerging Markets Index¹⁶ returning 4.36% during the reporting period.

Annual Shareholder Report

Interest rates increased across the maturity spectrum during the period, while credit spreads were generally flat leading to a modestly negative result for the BAB which returned -0.80%.¹⁷

Real Estate Investment Trust (REIT) performance was hindered by the increase in interest rates, with the MSCI REIT Index¹⁸ returning 3.12% during the reporting period.

EQUITIES

Domestic equity investments outperformed the broad market as measured by the R3000 during the period. Investments in the Health Care, Consumer Staples and Energy sectors were the most significant positive factors in the Fund's domestic equity performance relative to the R3000, while investments in the Utilities and Financials sectors were the most significant negative contributors to relative results.

ASSET ALLOCATION

While there was some fluctuation, the stock/bond allocation was consistently positioned to be overweight equities throughout the period. This was a positive for relative performance as equities solidly outperformed fixed-income investments over the course of the reporting period.

FIXED INCOME

During the reporting period, the fixed-income portion of the portfolio outperformed the BAB with duration management as the most significant contributor to relative performance. Interest rate exposure ranged from 90 to 95% of that of the benchmark, which helped performance as interest rates increased. Sector allocation and security selection also contributed positively over the reporting period.

Average Annual Total Returnsfor the Periods Ended 7/31/2018

(returns reflect all applicable sales charges and contingent deferred sales charges as specified below in footnote #1)

	1 Year	5 Years	10 Years
Class A Shares	5.77%	6.59%	5.58%
Class C Shares	10.09%	6.99%	5.39%
Institutional Shares	12.15%	8.07%	6.44%
Class R6 Shares⁵	12.24%	7.75%	5.91%
S&P 500	16.24%	13.12%	10.67%
BAB	(0.80)%	2.25%	3.73%
Blended Index	9.23%	8.79%	8.13%
MA50-70	7.08%	6.55%	6.62%

1	Represents a hypothetical investment of $10,000 in the Fund after deducting applicable sales charges: for Class A Shares, the maximum sales charge of 5.50% ($10,000 investment minus $550 sales charge = $9,450); for Class C Shares, a 1.00% contingent deferred sales charge would be applied on any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The S&P 500, BAB and MA50-70 have been adjusted to reflect reinvestment of dividends on securities in the indexes.
2	The S&P 500 Index, a broad-based securities market index of the Fund, is an unmanaged capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. The S&P 500 is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The S& P 500 is not adjusted to reflect sales charges, expenses or other fees that the Securities and Exchange Commission (SEC) requires to be reflected in the Fund's performance.
3	The BAB Index, a broad-based securities market index of the Fund, is a broad-based benchmark that measures the investment-grade, U.S. dollar-denominated, fixed-rate taxable bond market. The BAB is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The BAB is not adjusted to reflect sales charges, expenses or other fees that the SEC requires to be reflected in the Fund's performance.

Annual Shareholder Report

Morningstar figures represent the average of the total returns reported by all the funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges. The Morningstar figures in the Growth of $10,000 line graph are based on historical return information published by Morningstar and reflect the return of the funds comprising the category in the year of publication. Because the funds designated by Morningstar as falling into the category can change over time, the Morningstar figures in the line graph may not match the Morningstar figures in the Average Annual Total Returns table, which reflect the return of the funds that currently comprise the category.

Prior to September 1, 2016, Class R6 Shares were known as Class R Shares and included 12b-1 fees and certain other expenses. As of September 1, 2016, Class R6 does not include such 12b-1 fees and certain other expenses, and the performance shown above for Class R6 prior to September 1, 2016, reflects the higher Class R expenses.

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.

Notes to Financial Statements

July 31, 2018

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, Institutional Shares and Class R6 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.

Prior to their re-designation on September 1, 2016, Class R6 Shares were Class R Shares.

On March 30, 2017, the Fund's T Share class became effective with the Securities and Exchange Commission (SEC), but is not yet offered for sale.

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 GAAP.

Investment Valuation

In calculating its 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 are fair valued using price evaluations provided by a pricing service approved by the Fund's Board of Trustees (the “Trustees”).
■	Shares of other mutual funds or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	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 last traded or purchase price of the security, information obtained by contacting the issuer or dealers, 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, public trading in similar securities or derivative contracts of the issuer or comparable issuers, movement of a relevant index, or other factors including but not limited to industry changes and relevant government actions.

Annual Shareholder Report

representative of the fair value of such security, 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 obtain the fair value assigned to an investment if it sold the investment at approximately the time at which the Fund determines its NAV per share.

Fair Valuation and Significant Events Procedures

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 principally in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures contracts;
■	Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded;
■	Announcements concerning matters such as acquisitions, recapitalizations, litigation developments, or a natural disaster affecting the issuer's operations or regulatory changes or market developments affecting the issuer's industry.

Annual Shareholder Report

The Trustees have adopted procedures whereby the Valuation Committee uses 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 in accordance with the fair valuation procedures approved by the Trustees. The Trustees have ultimate responsibility for any fair valuations made in response to a significant event.

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. Amortization/accretion of premium and discount is included in investment income. Gains and losses realized on principal payment of mortgage-backed securities (paydown gains and losses) are classified as part of investment income. Positive or negative inflation adjustments on Treasury Inflation-Protected Securities are included in interest income. 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.

Annual Shareholder Report

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 select classes will bear certain expenses unique to those classes. The detail of the total fund expense waiver and reimbursements of $63,433 is disclosed in this Note 2 and Note 5. For the year ended July 31, 2018, transfer agent fees for the Fund were as follows:

	Transfer Agent Fees Incurred	Transfer Agent Fees Reimbursed
Class A Shares	$72,512	$(25,563)
Class C Shares	24,223	(6,453)
Institutional Shares	25,820	(1,512)
Class R6 Shares	5,457	—
TOTAL	$128,012	$(33,528)

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.

Other Service Fees

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Class A Shares and Class C Shares to unaffiliated financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Subject to the terms described in the Expense Limitation note, FSSC may voluntarily reimburse the Fund for other service fees. For the year ended July 31, 2018, other service fees for the Fund were as follows:

	Other Service Fees Incurred
Class A Shares	$138,660
Class C Shares	71,314
TOTAL	$209,974

Federal Taxes

Annual Shareholder Report

When-Issued and Delayed-Delivery Transactions

Futures Contracts

The Fund purchases and sells financial futures contracts to manage duration and yield curve risks. Upon entering into a financial futures contract with a broker, the Fund is required to deposit in a segregated account, either U.S. government securities or a specified amount of Restricted cash, which is shown in the Statement of Assets and Liabilities. 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 contracts are exchange traded and the exchange's clearinghouse, as counterparty to all exchange traded futures contracts, guarantees the futures contracts 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 $6,485,094 and $3,691,077, 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 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, like other securities, are priced in accordance with procedures established by and under the general supervision of the Trustees.

Securities Lending

Annual Shareholder Report

plus interest, if applicable. In accordance with the Fund's securities lending agreement, the market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Fund on the next business day. Earnings on collateral are allocated between the borrower of the security, the securities lending agent, as a fee for its services under the program and the Fund, according to agreed-upon rates.

Securities lending transactions are subject to Master Netting Agreements. Amounts presented on the Portfolio of Investments and Statement of Assets and Liabilities are not net settlement amounts but gross. As indicated below, the cash collateral received by the Fund exceeds the market value of the securities loaned reducing the net settlement amount to zero. The chart below identifies the amount of collateral received as well as the market value of securities on loan. Additionally, the securities lending agreement executed by the Fund includes an indemnification clause. This clause stipulates that the borrower will reimburse the Fund for any losses as a result of any failure of the borrower to return equivalent securities to the Fund.

4. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due to differing treatments for return of capital adjustments and short-term capital gain distributions from registered investment companies.

For the year ended July 31, 2018, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)
$(38,415)	$38,415

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for deferral of losses on wash sales, mark to market of futures contracts, deferral of paydown losses, partnership adjustments and non-taxable dividends.

Net investment income (loss), net realized gains (losses), and net assets were not affected by this reclassification.

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended July 31, 2018 and 2017, was as follows:

	2018	2017
Ordinary income	$1,769,092	$2,051,542

As of July 31, 2018, the components of distributable earnings on a tax-basis were as follows:

Undistributed ordinary income	$3,313,891
Net unrealized appreciation	$8,400,496
Undistributed long-term capital gains	$4,017,549

Annual Shareholder Report

At July 31, 2018, the cost of investments for federal tax purposes was $147,724,409. The net unrealized appreciation of investments for federal tax purposes was $8,400,496. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $13,153,368 and net unrealized depreciation from investments for those securities having an excess of cost over value of $4,752,872. The amounts presented are inclusive of derivative contracts.

The Fund used capital loss carryforwards of $4,176,449 to offset capital gains realized during the year ended July 31, 2018.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

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 and/or reimburse certain operating expenses of the Fund. For the year ended July 31, 2018, the Adviser voluntarily waived $27,437 of its fee and voluntarily reimbursed $33,528 of transfer agent fees.

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 year ended July 31, 2018, the Sub-Adviser earned a fee of $107,273.

Administrative Fee

Administrative Fee	Average Daily Net Assets of the Investment Complex
0.100%	on assets up to $50 billion
0.075%	on assets over $50 billion

Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the year ended July 31, 2018, the annualized fee paid to FAS was 0.080% of average daily net assets of the Fund.

Annual Shareholder Report

0.125%	on the next $5 billion
0.100%	on the next $10 billion
0.075%	on assets in excess of $20 billion

In addition, FAS may charge certain out-of-pocket expenses to the Fund.

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, Institutional Shares and Class R6 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:

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

Subject to the terms described in the Expense Limitation note, FSC may voluntarily choose to waive any portion of its fee. For the year ended July 31, 2018, distribution services fees for the Fund were as follows:

	Distribution Services Fees Incurred
Class C Shares	$216,329

When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the year ended July 31, 2018, FSC retained $33,139 of fees paid by the Fund. For the year ended July 31, 2018, 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 year ended July 31, 2018, FSC retained $12,640 in sales charges from the sale of Class A Shares. FSC also retained $7,006 of CDSC relating to redemptions of Class A Shares and $830 relating to redemptions of Class C Shares.

Other Service Fees

For the year ended July 31, 2018, FSSC received $12,629 of the other service fees disclosed in Note 2.

Annual Shareholder Report

Expense Limitation

The Adviser and certain of its affiliates (which may include FSC, FAS and FSSC) on their own initiative have agreed to waive certain amounts of their respective fees and/or reimburse expenses. Effective October 1, 2018, total annual fund operating expenses (as shown in the financial highlights, excluding interest expense, extraordinary expenses and proxy-related expenses paid by the Fund, if any) paid by the Fund's Class A Shares, Class C Shares, Institutional Shares and Class R6 Shares (after the voluntary waivers and/or reimbursements) will not exceed 1.31%, 2.06%, 1.06% and 1.05% (the “Fee Limit”), respectively, up to but not including the later of (the “Termination Date”): (a) October 1, 2019; or (b) the date of the Fund's next effective Prospectus.

Evaluation and Approval of Advisory Contract–May 2018

Federated MDT Balanced Fund (the “Fund”)

At its meetings in May 2018, the Fund's Board of Trustees (the “Board”), including a majority of those Trustees who are not “interested persons” of the Fund, as defined in the Investment Company Act of 1940 (the “Independent Trustees”] reviewed and unanimously approved the continuation of the Fund's investment advisory and subadvisory contracts for an additional one-year term. The Board's decision regarding these contracts reflects the exercise of its business judgment after considering all of the information received on whether to continue the existing arrangements.

The Board had previously appointed a Senior Officer, whose duties included specified responsibilities relating to the process by which advisory fees are to be charged to a fund advised by Federated MDTA LLC (the “Adviser”) or its affiliates (collectively, “Federated”) (each, a “Federated fund”). The Senior Officer's responsibilities included preparation and furnishing to the Board an annual independent written evaluation that covered topics discussed below. In December 2017, the Senior Officer position was eliminated. Notwithstanding the elimination of the Senior Officer position, at the request of the Independent Trustees, the Fund's Chief Compliance Officer (the CCO) furnished to the Board in advance of its May 2018 meetings an independent written evaluation covering substantially the same topics that had been covered in the Senior Officer's written evaluation in prior years. The Board considered the CCO's independent written evaluation (the “CCO Fee Evaluation Report”), along with other information, in evaluating the reasonableness of the Fund's management fee and in deciding to approve the continuation of the investment advisory and subadvisory contracts. Consistent with the former Senior Officer position, the CCO, in preparing the CCO Fee Evaluation Report, has the authority to retain consultants, experts or staff as reasonably necessary to assist in the performance of his duties, reports directly to the Board, and can be terminated only with the approval of a majority of the Independent Trustees.

Annual Shareholder Report

research services received from brokers that execute fund trades and any fees paid to affiliates of an adviser for services rendered to a fund); (5) comparative fee and expense structures (including a comparison of fees paid to an adviser with those paid by similar funds both internally and externally as well as management fees charged to institutional and other advisory clients of the Adviser or its affiliates for what might be viewed as like services); and (6) the extent of care, conscientiousness and independence with which the fund's board members perform their duties and their expertise (including whether they are fully informed about all facts the board deems relevant to its consideration of an adviser's services and fees). The Board noted that the Securities and Exchange Commission (SEC) disclosure requirements regarding the basis for the Board's approval of the Fund's investment advisory contract generally align with the factors listed above. The Board was aware of these factors and was guided by them in its review of the Fund's investment advisory and subadvisory contracts to the extent it considered them to be appropriate and relevant, as discussed further below.

In addition to the extensive materials that comprise and accompany the CCO Fee Evaluation, the Board received detailed information about the Fund and the Federated organization throughout the year, and in connection with its May meetings at which the Board's formal approval of the advisory and subadvisory contracts occurred. In this regard, Federated provided much of this information at each regular meeting of the Board, and furnished additional information specifically in connection with the May meetings. In the months preceding the May meetings, the Board requested and reviewed written materials prepared by Federated in response to requests on behalf of the Independent Trustees encompassing a wide variety of topics. At the May meetings, in addition to meeting in separates sessions of the Independent Trustees without management present, senior management of the Adviser also met with the Independent Trustees and their counsel to discuss the materials presented and such additional matters as the Independent Trustees deemed reasonably necessary to evaluate the advisory and subadvisory contracts. Between regularly scheduled meetings, the Board also received information on particular matters as the need arose.

The Board's consideration of the investment advisory and subadvisory contracts included review of the CCO Fee Evaluation Report, accompanying data and additional information covering the following matters, among others: the Adviser's and sub-adviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short-term and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in terms relative 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 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; the entrepreneurial and other risks assumed by the Adviser in sponsoring the Fund; 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 funds which include a comprehensive array of funds with different investment objectives, policies and strategies which are generally 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.

The Board reviewed the contractual advisory fee rate, net advisory fee rate and other expenses of the Fund and noted the position of the Fund's fee rates relative to its Peer Group. In this regard, the Board noted that the contractual advisory fee rate was above the median of the relevant Peer Group, but the Board noted the applicable waivers and reimbursements, and that the overall expense structure of the Fund remained competitive in the context of other factors considered by the Board. In this regard, the Board had been previously advised that, while comparisons to fund Peer Groups are relevant in judging the reasonableness of advisory fees, the Fund's quantitative focus makes fee and expense comparisons particularly difficult. Although the Fund's advisory fee was above the median of the peer range, the Peer Group of funds varied widely in their complexity, and the Board has been informed that the management of the Fund is among the more complex relative to its Peer Group.

Following such evaluation, and full deliberations, the Board concluded that the fees and expenses of the Fund are reasonable and supported renewal of the Fund's investment advisory and subadvisory contracts.

Annual Shareholder Report

addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day management of the Fund and the Adviser's ability and experience in attracting and retaining qualified personnel to service the Fund. The Board noted the compliance program of the Adviser and the compliance-related resources provided to the Fund by the Adviser, including the Adviser's commitment to respond to rulemaking initiatives of the SEC. The Fund's ability to deliver competitive performance when compared to its Peer Group was also deemed to be relevant by the Board as a useful indicator of how the Adviser is executing the Fund's investment program. The Adviser's ability to execute this program was one of the Board's considerations in reaching a conclusion that the nature, extent and quality of the Adviser's investment management services warrant the continuation of the investment advisory and subadvisory contracts.

For the periods covered by the CCO Fee Evaluation Report, the Fund's performance for the one-year period was above the median of the relevant Peer Group, and the Fund's performance fell below the median of the relevant Peer Group for the three-year and five-year periods. The Board discussed the Fund's performance with the Adviser and recognized the efforts being taken by the Adviser in the context of other factors considered relevant by the Board.

Following such evaluation, and full deliberations, the Board considered that the performance of the Fund supported renewal of the Fund's investment advisory and subadvisory contracts.

The Board also received financial information about Federated, including information regarding the compensation and ancillary (or “fall out”) benefits Federated derived from its relationships with the Federated funds. This information covered not only the fees under the investment 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 and distributor). In this regard, the Board considered that

Annual Shareholder Report

certain Federated subsidiaries provide distribution and shareholder services to the Federated funds, for which they may be compensated through distribution and servicing fees paid pursuant to Rule 12b-1 plans or otherwise. 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 Federated fund to be competitive in the marketplace, the Adviser and its affiliates frequently waived fees and/or reimbursed expenses and have disclosed to Federated fund investors and/or indicated to the Board their intention to do so in the future. Moreover, the Board receives regular reporting as to the institution, adjustment or elimination of these voluntary waivers. The Board considered Federated's previous reduction in contractual management fees to certain Federated funds in response to the CCO's recommendations.

Federated furnished information, requested by the CCO, 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 CCO. The CCO noted that, while these cost allocation reports apply consistent allocation processes, the inherent difficulties in allocating costs continues to cause the Senior Officer to question the precision of the process and to conclude that such reports may be unreliable, since a single change in an allocation estimate may dramatically alter the resulting estimate of cost and/or profitability of a Federated fund and may produce unintended consequences. The allocation information, including the CCO's view that fund-by-fund estimations may be unreliable, was considered in the evaluation by the Board.

Annual Shareholder Report

such waivers and reimbursements can provide protection from an increase in expenses if a Federated fund's assets decline. Federated, as it does throughout the year, and specifically in connection with the Board's review of the advisory and subadvisory contracts, furnished information relative to revenue sharing or adviser-paid fees. Federated and the CCO noted that this information should be viewed to determine if there was an incentive to either not apply breakpoints, or to apply breakpoints at higher levels, and should not be viewed to determine the appropriateness of advisory fees because it would represent marketing and distribution expenses. The Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the CCO Fee Evaluation Report) 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 a fund attains a certain size.

The CCO stated that his observations and the information accompanying the CCO Fee Evaluation Report supported a finding by the Board that the management fee for the Fund was reasonable. Under these circumstances, no changes were recommended to, and no objection was raised to, the continuation of the Fund's investment advisory and subadvisory contracts. The CCO also recognized that the Board's evaluation of the Federated funds' advisory and subadvisory arrangements is a continuing and on-going process that is informed by the information that the Board requests and receives from management throughout the course of the year and, in this regard, the CCO noted certain items for future reporting to the Board or further consideration by management as the Board continues its on-going oversight of the Federated funds.

Management's Discussion of Fund Performance (unaudited)

The total return of Federated MDT Large Cap Growth Fund (the “Fund”), based on net asset value for the 12-month reporting period ended July 31, 2018, was 27.38% for Class A Shares, 26.38% for Class B Shares, 26.42% for Class C Shares and 27.65% for the Institutional Shares. The total return for the Russell 1000^® Growth Index (R1000G),¹ the Fund's broad-based securities market index, was 22.84% for the same period. The total return of the Morningstar Large Growth Funds Average (MLGFA),² a peer group average for the Fund, was 20.31% during the same period. The Fund's and MLGFA's total returns for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the R1000G.

During the reporting period, the Fund's investment strategy focused on stock selection. This was the most significant factor affecting the Fund's performance relative to the R1000G during the period.

The following discussion will focus on the performance of the Fund's Institutional Shares.

MARKET OVERVIEW

During the reporting period, overall domestic equity market performance was strong as evidenced by the 16.39% return of the whole-market Russell 3000^® Index.³ On average, very small-cap stocks⁴ had the best year, followed by very large-cap stocks: the Russell Microcap^® Index⁵ returned 20.80%, the small-cap Russell 2000^® Index⁶ returned 18.73%, and the Russell Top 200^® Index⁷ returned 17.28%. Mid-cap stocks trailed for the year with the Russell Midcap^® Index⁸ returning 13.45%. For style, growth led value by a substantial margin in August 2017, October 2017, January 2018, February 2018, and May 2018. While there were some months that did favor value slightly, they did little to offset the cumulative difference: for the year, the Russell 3000^® Growth Index⁹ returned 22.86%, and the Russell 3000^® Value Index¹⁰ returned 9.91%.

The best performing sectors in the R1000G during the reporting period were Utilities (31.15%), Information Technology (29.84%) and Consumer Discretionary (27.52%). (While the Utilities sector had the highest return, the average weight of the Utilities sector in the R1000G is very small (0.01%)). Underperforming sectors during the same period included Telecommunication Services (5.73%), Consumer Staples (7.93%) and Materials (8.70%).

Annual Shareholder Report

STOCK SELECTION

When looking at the Fund's outperformance in terms of fundamental and technical characteristics, the most significant drivers of outperformance during the reporting period were stocks with very high analyst conviction and prices near 52-week highs. Stocks with those characteristics outperformed the benchmark, and the Fund overweighted them and selected well among them. Stocks with prices near 52-week highs, strong cash flow and neutral to high analyst conviction were also overweighted, but those stocks underperformed and detracted the most from performance. The Fund's sector exposures at the end of the period were close to R1000G weights, except for a small underweight in the Real Estate sector and a small overweight in the Information Technology sector. Favorable stock selection in the Health Care, Consumer Discretionary and Industrials sectors contributed the most to the Fund's outperformance during the reporting period.

Individual stocks enhancing the Fund's performance during the reporting period included Align Technology, Inc., W.W. Grainger, Inc. and Salesforce.com, Inc.

Individual stocks detracting from the Fund's performance during the reporting period included Microsoft Corporation, Alphabet, Inc. and Boeing Company. All three outperformed the R1000G, but Alphabet was not held by the Fund and Microsoft and Boeing were underweighted relative to the R1000G.

2	Morningstar has assigned the Fund to the Morningstar Large Blend Funds Average peer group, however, the MLGFA is being used for comparison purposes. The Fund invests in growth stocks, and therefore, the Fund's Adviser believes that the MLGFA is more reflective of the Fund's investment style. Please see the footnotes to the line graphs below for definitions of, and further information about, the MLGFA.

FUND PERFORMANCE AND GROWTH OF A $10,000 INVESTMENT

The graph below illustrates the hypothetical investment of $10,000¹ in the Federated MDT Large Cap Growth Fund (the “Fund”) from July 31, 2008 to July 31, 2018, compared to the Russell 1000^® Growth Index (R1000G)²and the Morningstar Large Growth Funds Average (MLGFA).³The Average Annual Total Return table below shows returns for each class averaged over the stated periods.

Growth of a $10,000 Investment

Growth of $10,000 as of July 31, 2018

■	Total returns shown for Class C Shares include the maximum contingent deferred sales charge of 1.00% as applicable.

The Fund offers multiple share classes whose performance may be greater than or less than its other share class(es) due to differences in sales charges and expenses. See the Average Annual Return table below for the returns of additional classes not shown in the line graph above.

Average Annual Total Returnsfor the Period Ended 7/31/2018

(returns reflect all applicable sales charges and contingent deferred sales charge as specified below in footnote #1)

	1 Year	5 Years	10 Years
Class A Shares	20.35%	11.76%	8.75%
Class B Shares	20.88%	11.92%	8.71%

Annual Shareholder Report

1	Represents a hypothetical investment of $10,000 in the Fund after deducting applicable sales charges: for Class A Shares, the maximum sales charge of 5.50% ($10,000 investment minus $550 sales charges = $9,450); for Class B Shares, the maximum contingent deferred sales charge is 5.50% on any redemption less than one year from the purchase date; for Class C Shares, a 1.00% contingent deferred sales charge would be applied to any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The R1000G and MLGFA have been adjusted to reflect reinvestment of dividends on securities.
2	The R1000G measures the performance of the large-cap growth segment of the U.S. equity universe. It includes those Russell 1000^® Index companies with higher price-to-book ratios and higher forecasted growth values. The R1000G is constructed to provide a comprehensive and unbiased barometer for the large-cap growth segment. The R1000G is completely reconstituted annually to ensure new and growing equities are included and that the represented companies continue to reflect growth characteristics. The R1000G is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The R1000G is not adjusted to reflect sales charges, expenses or other fees that the Securities and Exchange Commission requires to be reflected in the Fund's performance.
3	Morningstar figures represent the average of the total returns reported by all the funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges. The Morningstar figures in the Growth of $10,000 line graph are based on historical return information published by Morningstar and reflect the return of the funds comprising the category in the year of publication. Because the funds designated by Morningstar as falling into the category can change over time, the Morningstar figures in the line graph may not match the Morningstar figures in the Average Annual Total Returns table, which reflect the return of the funds that currently comprise the category.

Notes to Financial Statements

July 31, 2018

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.

On March 30, 2017, the Fund's T Share class became effective with the Securities and Exchange Commission (SEC), but is not yet offered for sale.

Effective December 1, 2017, Class B Shares of the Fund were closed to new accounts and to new investors.

Effective February 1, 2018, Class B Shares were closed to exchanges from Class B Shares of other Federated Funds and to new purchases made by existing shareholders (excluding reinvestment of dividends and capital gains).

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 or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Fixed-income securities are fair valued using price evaluations provided by a pricing service approved by the Fund's Board of Trustees (the “Trustees”).
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	Over-the-counter (OTC) derivative contracts are fair valued using price evaluations provided by a pricing service approved by the Trustees.

Annual Shareholder Report

■

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 last traded or purchase price of the security, information obtained by contacting the issuer or dealers, 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, public trading in similar securities or derivative contracts of the issuer or comparable issuers, movement of a relevant index, or other factors including but not limited to industry changes and relevant government actions.

If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, if the Fund cannot obtain price evaluations from a pricing service or from more than one dealer for an investment within a reasonable period of time as set forth in the Fund's valuation policies and procedures, or if information furnished by a pricing service, in the opinion of the valuation committee (“Valuation Committee”), is deemed not representative of the fair value of such security, 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 obtain the fair value assigned to an investment if it sold the investment at approximately the time at which the Fund determines its NAV per share.

Fair Valuation Procedures

Annual Shareholder Report

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. Amortization/accretion of premium and discount is included in investment income. 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 select classes will bear certain expenses unique to those classes. The detail of the total fund expense waiver and reimbursement of $18,388 is disclosed in various locations in Note 5.

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.

Annual Shareholder Report

Other Service Fees

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Class A Shares, Class B Shares and Class C Shares to unaffiliated financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Subject to the terms described in the Expense Limitation note, FSSC may voluntarily reimburse the Fund for other service fees. For the year ended July 31, 2018, other service fees for the Fund were as follows:

	Other Service Fees Incurred
Class A Shares	$138,388
Class B Shares	35,594
Class C Shares	25,466
TOTAL	$199,448

Federal Taxes

When-Issued and Delayed-Delivery Transactions

Securities Lending

Annual Shareholder Report

market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Fund on the next business day. Earnings on collateral are allocated between the borrower of the security, the securities lending agent, as a fee for its services under the program and the Fund, according to agreed-upon rates.

As of July 31, 2018, securities subject to this type of arrangement and related collateral were as follows:

Market Value of Securities Loaned	Market Value of Collateral
$276,854	$280,960

4. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due to differing treatments for net operating losses and return of capital adjustments.

Increase (Decrease)
Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for wash sales and non-taxable dividends.

At July 31, 2018, the cost of investments for federal tax purposes was $77,956,868. The net unrealized appreciation of investments for federal tax purposes was $19,158,760. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $22,053,652 and net unrealized depreciation from investments for those securities having an excess of cost over value of $2,894,892.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

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.

Evaluation and Approval of Advisory Contract–May 2018

Federated MDT Large Cap Growth Fund (the “Fund”)

Annual Shareholder Report

The CCO noted that the services, administrative responsibilities and risks associated with such relationships are quite different than serving as a primary adviser to a fund.

Following such evaluation, and full deliberations, the Board concluded that the fees and expenses of the Fund are reasonable and supported renewal of the Fund's investment advisory contract.

Annual Shareholder Report

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 CCO Fee Evaluation Report. In addition, the Board was informed by the Adviser that, for the same periods, the Fund underperformed its benchmark index for the one-year, three-year and five-year periods. The Board discussed the Fund's performance with the Adviser and recognized the efforts being taken by the Adviser in the context of other factors considered relevant by the Board.

Following such evaluation, and full deliberations, the Board concluded that the performance of the Fund supported renewal of the Fund's advisory contract.

Management's Discussion of Fund Performance (unaudited)

The total return of Federated MDT Small Cap Core Fund (the “Fund”), based on net asset value for the 12-month reporting period ended July 31, 2018, was 18.49% for Class A Shares, 17.60% for Class C Shares, 18.78% for Institutional Shares and 18.78% for Class R6 Shares. The total return for the Russell 2000^® Index (R2000),¹ the Fund's broad-based securities market index, was 18.73% for the same period. The total return of the Morningstar Small Blend Funds Average (MSBFA),² a peer group average for the Fund, was 15.80% during the same period. The Fund's and MSBFA's total returns for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the R2000.

During the reporting period, the Fund's investment strategy focused on stock selection. This was the most significant factor affecting the Fund's performance relative to the R2000 during the period.

The following discussion will focus on the performance of the Fund's Institutional Shares.

MARKET OVERVIEW

During the reporting period, overall domestic equity market performance was strong as evidenced by the 16.39% return of the whole-market Russell 3000^® Index.³ On average, very small-cap stocks⁴ had the best year, followed by very large-cap stocks: the Russell Microcap^® Index⁵ returned 20.80%; the small-cap R2000 returned 18.73%; and the Russell Top 200^® Index⁶ returned 17.28%. Mid-cap stocks trailed for the year with the Russell Midcap^® Index⁷ returning 13.45%. For style, growth led value by a substantial margin in August 2017, October 2017, January 2018, February 2018 and May 2018. While there were some months that did favor value slightly, they did little to offset the cumulative difference: for the year, the Russell 3000^® Growth Index⁸ returned 22.86% and the Russell 3000^® Value Index⁹ returned 9.91%.

The best performing sectors in the R2000 during the reporting period were Health Care (33.62%), Industrials (20.17%) and Consumer Discretionary (19.62%). Underperforming sectors during the same period included Real Estate (3.50%), Utilities (5.67%) and Telecommunication Services (8.18%).

STOCK SELECTION

When looking at the Fund's fundamental and technical characteristics, outperformance during the growth-oriented reporting period came from stocks with significant need for external financing, but other strong fundamental characteristics. Additional contribution came from stocks with prices near 52-week highs and sell-side analyst conviction that was not low. Much of this performance was offset by negative contribution from stocks with high structural earnings, but low analyst conviction and low cash flow, and from stocks with high structural earnings and depressed prices. The Fund's sector

Annual Shareholder Report

exposures remained close to R2000 weights, but with an overweight in the Financials sector and an underweight in the Real Estate sector. Strong stock selection in the Information Technology sector and underweighting the Real Estate sector contributed the most to the Fund's outperformance. Weak stock selection in the Consumer Discretionary, Telecommunication Services and Industrials sectors provided a partial offset.

Individual stocks enhancing the Fund's performance during the reporting period included Medifast, Inc., Pinnacle Entertainment Inc. and Cabot Microelectronics Corporation.

Individual stocks detracting from the Fund's performance during the reporting period included Frontier Communications Corporation, iRobot Corporation and GNC Holdings, Inc.

FUND PERFORMANCE AND GROWTH OF A $10,000 INVESTMENT

The graph below illustrates the hypothetical investment of $10,000¹ in the Federated MDT Small Cap Core Fund from July 31, 2008 to July 31, 2018, compared to the Russell 2000^® Index (R2000)² and the Morningstar Small Blend Funds Average (MSBFA).³ The Average Annual Total Return table below shows returns for each class averaged over the stated periods.

Growth of a $10,000 INVESTMENT

Growth of $10,000 as of July 31, 2018

■	Total returns shown for Class C Shares include the maximum contingent deferred sales charge of 1.00%, as applicable.

The Fund offers multiple shares classes whose performance may be greater than or less than its other share class(es) due to differences in sales charges and expenses. See the Average Annual Total Returns table below for the returns of additional classes not shown in the line graph above.

Average Annual Total Returnsfor the Periods Ended 7/31/2018

(returns reflect all applicable sales charges and contingent deferred sales charges as specified below in footnote #1)

	1 Year	5 Years	10 Years
Class A Shares	11.96%	12.85%	9.41%
Class C Shares	16.60%	13.29%	9.20%
Institutional Shares	18.78%	14.44%	10.28%
Class R6 Shares⁴	18.78%	14.28%	8.40%
R2000	18.73%	11.33%	10.39%
MSBFA	15.80%	10.01%	9.80%

Annual Shareholder Report

1	Represents a hypothetical investment of $10,000 in the Fund after deducting applicable sales charges: for Class A Shares, the maximum sales charge of 5.50% ($10,000 investment minus $550 sales charge = $9,450); for Class C Shares, a 1.00% contingent deferred sales charge would be applied on any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The R2000 and MSBFA have been adjusted to reflect reinvestment of dividends on securities.
2	The R2000 measures the performance of the small-cap segment of the U.S. equity universe. The R2000 is a subset of the Russell 3000^® Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2000 of the smallest securities based on a combination of their market cap and current index membership. The R2000 is constructed to provide a comprehensive and unbiased small-cap barometer, and is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small-cap opportunity set. The R2000 is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The R2000 is not adjusted to reflect sales charges, expenses or other fees that the Securities and Exchange Commission requires to be reflected in the Fund's performance.
3	Morningstar figures represent the average of the total returns reported by all the funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges. The Morningstar figures in the Growth of $10,000 line graph are based on historical return information published by Morningstar and reflect the return of the funds comprising the category in the year of publication. Because the funds designated by Morningstar as falling into the category can change over time, the Morningstar figures in the line graph may not match the Morningstar figures in the Average Annual Total Returns table, which reflect the return of the funds that currently comprise the category.

Notes to Financial Statements

July 31, 2018

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 four classes of shares: Class A Shares, Class C Shares, Institutional Shares and Class R6 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.

On March 30, 2017, the Fund's T Share class became effective with the Securities and Exchange Commission (SEC), but is not yet offered for sale.

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 or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Fixed-income securities are fair valued using price evaluations provided by a pricing service approved by the Trustees.
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	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 last traded or purchase price of the security, information obtained by contacting the issuer or dealers, 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, public trading in similar securities or derivative contracts of the issuer or comparable issuers, movement of a relevant index, or other factors including but not limited to industry changes and relevant government actions.

Annual Shareholder Report

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. Amortization/accretion of premium and discount is included in investment income. 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 select classes will bear certain expenses unique to those classes. The detail of the total fund expense waiver and reimbursements of $1,610,530 is disclosed in various locations in this Note 2 and Note 5. For the year ended July 31, 2018, transfer agent fees for the Fund were as follows:

	Transfer Agent Fees Incurred	Transfer Agent Fees Reimbursed
Class A Shares	$67,492	$(54,946)
Class C Shares	27,528	(22,441)
Institutional Shares	380,640	(297,679)
Class R6 Shares	728	—
TOTAL	$476,388	$(375,066)

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.

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Class A Shares and Class C Shares to unaffiliated financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts.

4. FEDERAL TAX INFORMATION

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended July 31, 2018 and 2017, was as follows:

	2018	2017
Ordinary income¹	$13,627,453	$819,290
Long-term capital gains	$1,903,067	$—

1	For tax purposes, short-term capital gain distributions are considered ordinary income distributions.

As of July 31, 2018, the components of distributable earnings on a tax-basis were as follows:

Undistributed ordinary income²	$12,099,427
Net unrealized appreciation	$70,250,528
Undistributed long-term capital gains	$1,712,560

2	For tax purposes, short-term capital gains are considered ordinary income in determining distributable earnings.

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for the deferral of losses on wash sales.

At July 31, 2018, the cost of investments for federal tax purposes was $867,687,694. The net unrealized appreciation of investments for federal tax purposes was $70,250,528.

Evaluation and Approval of Advisory Contract–May 2018

Federated MDT Small Cap Core Fund (the “Fund”)

Annual Shareholder Report

The CCO noted that the services, administrative responsibilities and risks associated with such relationships are quite different than serving as a primary adviser to a fund.

Following such evaluation, and full deliberations, the Board concluded that the fees and expenses of the Fund are reasonable and supported renewal of the Fund's investment advisory contract.

Annual Shareholder Report

Following such evaluation, and full deliberations, the Board concluded that the performance of the Fund supported renewal of the Fund's advisory contract.

Annual Shareholder Report

In 2016, the Board approved a reduction of 16 basis points in the contractual advisory fee. In 2018, the Board approved an additional reduction of 14 basis points in the contractual advisory fee. These changes were intended to more closely align the contractual fee with the net fee actually charged after the imposition of applicable voluntary waivers.

Annual Shareholder Report

The CCO Fee Evaluation Report also discussed the notion of possible realization of “economies of scale” as a fund grows larger. In this regard, the Board considered 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, shareholder services, compliance, internal audit and risk management functions, as well as systems technology (including technology relating to cybersecurity) and that the benefits of these efforts (as well as any economies of scale, should they exist) were likely to be shared with the Federated fund family as a whole. The Board noted that the Adviser's investments in these areas are extensive. In addition, the Board considered that the Adviser and its affiliates have frequently waived fees and/or reimbursed expenses and that this has allowed fund shareholders to share potential economies of scale with shareholders. The Board also considered that such waivers and reimbursements can provide protection from an increase in expenses if a Federated fund's assets decline. Federated, as it does throughout the year, and specifically in connection with the Board's review of the advisory and subadvisory contracts, furnished information relative to revenue sharing or adviser-paid fees. Federated and the CCO noted that this information should be viewed to determine if there was an incentive to either not apply breakpoints, or to apply breakpoints at higher levels, and should not be viewed to determine the appropriateness of advisory fees because it would represent marketing and distribution expenses. The Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the CCO Fee Evaluation Report) 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 a fund attains a certain size.

Annual Shareholder Report

Adviser will have a continuing role in providing advisory services to the Fund. Thus, the Board's approval of the investment 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 concluded that, in light of the factors summarized above, including the nature, quality and scope of the services provided to the Fund by the Adviser and its affiliates, continuation of the investment advisory contract was appropriate.

Management's Discussion of Fund Performance (unaudited)

The total return of Federated MDT Small Cap Growth Fund (the “Fund”), based on net asset value for the 12-month reporting period ended July 31, 2018, was 23.50% for Class A Shares, 22.54% for Class C Shares, 23.85% for Institutional Shares and 23.81% for Class R6 Shares. The total return for the Russell 2000^® Growth Index (R2000G),¹ the Fund's broad-based securities market index, was 22.91% for the same period. The total return of the Morningstar Small Growth Funds Average (MSGFA),² a peer group average for the Fund, was 22.76% during the same period. The Fund's and MSGFA's total returns for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the R2000G.

During the reporting period, the Fund's investment strategy focused on stock selection. This was the most significant factor affecting the Fund's performance relative to the R2000G during the period.

The following discussion will focus on the performance of the Fund's Institutional Shares.

MARKET OVERVIEW

During the reporting period, overall domestic equity market performance was strong as evidenced by the 16.39% return of the whole-market Russell 3000^® Index.³ On average, very small-cap stocks⁴ had the best year, followed by very large-cap stocks: the Russell Microcap^® Index⁵ returned 20.80%, the small-cap Russell 2000^® Index⁶ returned 18.73%, and the Russell Top 200^® Index⁷ returned 17.28%. Mid-cap stocks trailed for the year with the Russell Midcap^® Index⁸ returning 13.45%. For style, growth led value by a substantial margin in August 2017, October 2017, January 2018, February 2018 and May 2018. While there were some months that did favor value slightly, they did little to offset the cumulative difference: for the year, the Russell 3000^® Growth Index⁹ returned 22.86%, and the Russell 3000^® Value Index¹⁰ returned 9.91%.

The best performing sectors in the R2000G during the reporting period were Health Care (32.41%), Information Technology (23.39%), Consumer Discretionary (21.46%) and Consumer Staples (21.46%). Underperforming sectors during the same period included Utilities (1.87%), Real Estate (5.41%) and Materials (14.78%).

STOCK SELECTION

The Fund buys stocks with many different combinations of fundamental and technical characteristics that have signaled market outperformance historically. When looking at the Fund's combinations of these characteristics, the outperformance during the reporting period came primarily from growth-oriented stocks with prices near 52-week highs, high analyst conviction and low structural earnings, and from small cap growth stocks with relatively strong value

Annual Shareholder Report

characteristics (high structural earnings and favorable cash flow). Stocks with high analyst conviction and moderate to high structural earnings detracted the most from performance.

The Fund's sector exposures continued to remain close to R2000G weights, but with a small overweight in Consumer Discretionary and a small underweight in Real Estate. Strong stock selection in the Consumer Staples and Information Technology sectors, and underweighting the Real Estate sector contributed the most to Fund outperformance. Poor stock selection in the Health Care and Industrials sectors provided a partial offset.

Individual stocks enhancing the Fund's performance included Proto Labs, Inc., Shutterfly, Inc., Inogen, Inc. and USANA Health Sciences, Inc.

Individual stocks detracting from the Fund's performance included SAGE Therapeutics, Inc., iRobot Corporation and GNC Holdings, Inc.

FUND PERFORMANCE AND GROWTH OF A $10,000 INVESTMENT

The graph below illustrates the hypothetical investment of $10,000¹ in the Federated MDT Small Cap Growth Fundfrom July 31, 2008 to July 31, 2018, compared to the Russell 2000 Growth^® Index (R2000G)² and the Morningstar Small Growth Funds Average (MSGFA).³The Average Annual Total Return table below shows returns for each class averaged over the stated periods.

Growth of a $10,000 Investment

Growth of $10,000 as of July 31, 2018

■	Total returns shown for Class C Shares include the maximum contingent deferred sales charge of 1.00% as applicable.

Average Annual Total Returnsfor the Period Ended 7/31/2018

(returns reflect all applicable sales charges and contingent deferred sales charges as specified below in footnote #1)

	1 Year	5 Years	10 Years
Class A Shares	16.73%	13.84%	10.30%
Class C Shares	21.54%	14.28%	10.09%
Institutional Shares	23.85%	15.43%	11.20%
Class R6 Shares⁴	23.81%	15.35%	10.94%
R2000G	22.91%	12.38%	11.17%
MSGFA	22.76%	11.55%	10.96%

Annual Shareholder Report

1	Represents a hypothetical investment of $10,000 in the Fund after deducting applicable sales charges: for Class A Shares, the maximum sales charge of 5.50% ($10,000 investment minus $550 sales charges = $9,450); for Class C Shares, a 1.00% contingent deferred sales charge would be applied to any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The R2000G and MSGFA have been adjusted to reflect reinvestment of dividends on securities.
2	The R2000G measures the performance of the small-cap growth segment of the U.S. equity universe. It includes those Russell 2000^® Index companies with higher price-to-value ratios and higher forecasted growth values. The R2000G is constructed to provide a comprehensive and unbiased barometer for the small-cap growth segment. The R2000G is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small-cap opportunity set and that the represented companies continue to reflect growth characteristics. The R2000G is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index. The R2000G is not adjusted to reflect sales charges, expenses or other fees that the Securities and Exchange Commission requires to be reflected in the Fund's performance.
3	Morningstar figures represent the average of the total returns reported by all the funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges. The Morningstar figures in the Growth of $10,000 line graph are based on historical return information published by Morningstar and reflect the return of the funds comprising the category in the year of publication. Because the funds designated by Morningstar as falling into the category can change over time, the Morningstar figures in the line graph may not match the Morningstar figures in the Average Annual Total Returns table, which reflect the return of the funds that currently comprise the category.
4	The Fund's Class R6 Shares commenced operations on June 29, 2016. It is anticipated that this class will have the lowest net expenses of all outstanding share classes. For the period prior to the commencement of operations of Class R6 Shares, the performance information shown is for the Fund's Institutional Shares adjusted to reflect expenses of the Class R6 Shares for each year for which the gross expenses of Class R6 Shares would have exceeded the actual expenses paid by Institutional Shares.

Notes to Financial Statements

July 31, 2018

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 C Shares, Institutional Shares and Class R6 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.

On March 30, 2017, the Fund's T Share class became effective with the Securities and Exchange Commission (SEC), but is not yet offered for sale.

On February 2, 2018, Class B Shares were converted into the Fund's existing Class A Shares at the close of business pursuant to a Plan of Conversion approved by the Trustees. The conversion occurred on a tax-free basis. The cash value of a shareholder's investment was not changed as a result of the share class conversion. No action was required by shareholders to effect the conversion.

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 or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Fixed-income securities are fair valued using price evaluations provided by a pricing service approved by the Trustees.
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	Over-the-counter (OTC) derivative contracts are fair valued using price evaluations provided by a pricing service approved by the Trustees.

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. 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. Amortization/accretion of premium and discount is included in investment income. 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 select classes will bear certain expenses unique to those classes. The detail of the total fund expense waiver and reimbursements of $1,415,283 is disclosed in various locations in this Note 2 and Note 5. For the year ended July 31, 2018, transfer agent fees for the Fund were as follows:

	Transfer Agent Fees Incurred	Transfer Agent Fees Reimbursed
Class A Shares	$126,074	$(95,749)
Class B Shares	918	(608)
Class C Shares	19,036	(13,576)
Institutional Shares	331,555	(243,142)
Class R6 Shares	16,212	—
TOTAL	$493,795	$(353,075)

Annual Shareholder Report

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.

Other Service Fees

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Class A Shares, Class B Shares and Class C Shares to financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Subject to the terms described in the Expense Limitation note, FSSC may voluntarily reimburse the Fund for other service fees. For the year ended July 31, 2018, other service fees for the Fund were as follows:

4. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due to differing treatments for net operating loss and return of capital adjustments.

Annual Shareholder Report

For the year ended July 31, 2018, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)
$1,163,175	$(1,163,175)

Net investment income (loss), net realized gains (losses), and net assets were not affected by this reclassification.

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended July 31, 2018 and 2017, was as follows:

	2018	2017
Ordinary income¹	$11,703,942	$568,066
Long-term capital gains	$2,857,464	$1,047,165

1	For tax purposes, short-term capital gain distributions are considered ordinary income distributions.

As of July 31, 2018, the components of distributable earnings on a tax-basis were as follows:

Undistributed ordinary income²	$19,115,501
Net unrealized appreciation	$60,121,186
Undistributed long-term capital gains	$10,890,427

2	For tax purposes, short-term capital gains are considered ordinary income in determining distributable earnings.

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for deferral of losses on wash sales and return of capital adjustments.

At July 31, 2018, the cost of investments for federal tax purposes was $514,194,703. The net unrealized appreciation of investments for federal tax purposes was $60,121,186. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $73,207,934 and net unrealized depreciation from investments for those securities having an excess of cost over value of $13,086,748.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.85% of the Fund's average daily net assets. Prior to June 28, 2018, the annual advisory fee was 0.99% 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 year ended July 31, 2018, the Adviser voluntarily waived $1,054,428 of its fee and voluntarily reimbursed $353,075 of transfer agent fees.

Evaluation and Approval of Advisory Contract–May 2018

Federated MDT Small Cap Growth Fund (the “Fund”)

Annual Shareholder Report

Following such evaluation, and full deliberations, the Board concluded that the fees and expenses of the Fund are reasonable and supported renewal of the Fund's investment advisory contract.

(a) As of the end of the period covered by this report, the registrant has adopted a code of ethics (the "Section 406 Standards for Investment Companies - Ethical Standards for Principal Executive and Financial Officers") that applies to the registrant's Principal Executive Officer and Principal Financial Officer; the registrant's Principal Financial Officer also serves as the Principal Accounting Officer.

(c) There was no amendment to the registrant’s code of ethics described in Item 2(a) above during the period covered by the report.

(d) There was no waiver granted, either actual or implicit, from a provision to the registrant’s code of ethics described in Item 2(a) above during the period covered by the report.

(f)(3) The registrant hereby undertakes to provide any person, without charge, upon request, a copy of the code of ethics. To request a copy of the code of ethics, contact the registrant at 1-800-341-7400, and ask for a copy of the Section 406 Standards for Investment Companies - Ethical Standards for Principal Executive and Financial Officers.

The registrant's Board has determined that each of the following members of the Board's Audit Committee is an “audit committee financial expert,” and is "independent," for purposes of this Item: John T. Collins, G. Thomas Hough and Thomas M. O'Neill.

(b) Audit-Related Fees billed to the registrant for the two most recent fiscal years:

Amount requiring approval of the registrant’s audit committee pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, $0 and $0, respectively.

(d) All Other Fees billed to the registrant for the two most recent fiscal years:

Amount requiring approval of the registrant’s audit committee pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, $32,377 and $33,951, respectively. Fiscal year ended 2018- Service fee for analysis of potential Passive Foreign Investment Company holdings. Fiscal year ended 2017- Service fee for analysis of potential Passive Foreign Investment Company holdings.

The Audit Committee is required to pre-approve audit and non-audit services performed by the independent auditor in order to assure that the provision of such services do not impair the auditor’s independence. Unless a type of service to be provided by the independent auditor has received general pre-approval, it will require specific pre-approval by the Audit Committee. Any proposed services exceeding pre-approved cost levels will require specific pre-approval by the Audit Committee.

Certain services have the general pre-approval of the Audit Committee. The term of the general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee specifically provides for a different period. The Audit Committee will annually review the services that may be provided by the independent auditor without obtaining specific pre-approval from the Audit Committee and may grant general pre-approval for such services. The Audit Committee will revise the list of general pre-approved services from time to time, based on subsequent determinations. The Audit Committee will not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

The Audit Committee has delegated pre-approval authority to its Chairman. The Chairman will report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Committee will designate another member with such pre-approval authority when the Chairman is unavailable.

The annual Audit services engagement terms and fees will be subject to the specific pre-approval of the Audit Committee. The Audit Committee must approve any changes in terms, conditions and fees resulting from changes in audit scope, registered investment company (RIC) structure or other matters.

In addition to the annual Audit services engagement specifically approved by the Audit Committee, the Audit Committee may grant general pre-approval for other Audit Services, which are those services that only the independent auditor reasonably can provide. The Audit Committee has pre-approved certain Audit services, all other Audit services must be specifically pre-approved by the Audit Committee.

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Company’s financial statements or that are traditionally performed by the independent auditor. The Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor, and has pre-approved certain Audit-related services, all other Audit-related services must be specifically pre-approved by the Audit Committee.

The Audit Committee believes that the independent auditor can provide Tax services to the Company such as tax compliance, tax planning and tax advice without impairing the auditor’s independence. However, the Audit Committee will not permit the retention of the independent auditor in connection with a transaction initially recommended by the independent auditor, the purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. The Audit Committee has pre-approved certain Tax services, all Tax services involving large and complex transactions must be specifically pre-approved by the Audit Committee.

With respect to the provision of services other than audit, review or attest services the pre-approval requirement is waived if:

The Audit Committee may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, and would not impair the independence of the auditor.

The SEC’s rules and relevant guidance should be consulted to determine the precise definitions of prohibited non-audit services and the applicability of exceptions to certain of the prohibitions.

Pre-approval fee levels for all services to be provided by the independent auditor will be established annually by the Audit Committee. Any proposed services exceeding these levels will require specific pre-approval by the Audit Committee.

Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the independent auditor and the Principal Accounting Officer and/or Internal Auditor, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

(e)(2) Percentage of services identified in items 4(b) through 4(d) that were approved by the registrants audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Percentage of services provided to the registrants investment adviser and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were approved by the registrants audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X, 0% and 0% respectively.

The registrant’s management and Audit Committee continue to believe that the registrant’s registered public accounting firm, Ernst & Young LLP (“EY”), has the ability to exercise objective and impartial judgment on all issues encompassed within their audit services. EY is required to make a determination that it satisfies certain independence requirements under the federal securities laws. Like other registrants, there is a risk that activities or relationships of EY, or its partners or employees, can prevent a determination from being made that it satisfies such independence requirements with respect to the registrant, which could render it ineligible to serve as the registrant’s independent public accountant.

In its required communications to the Audit Committee of the registrant’s Board, EY informed the Audit Committee that EY and/ or covered person professionals within EY maintain lending relationships with certain owners of greater than 10% of the shares of the registrant and/or certain investment companies within the “investment company complex” as defined under Rule 2-01(f)(14) of Regulation S-X, which are affiliates of the registrant. EY has advised the Audit Committee that these lending relationships implicate Rule 2-01(c)(1)(ii)(A) of Regulation S-X (referred to as the “Loan Rule”). The Loan Rule prohibits an independent public accountant, or covered person professionals at such firm, from having a financial relationship (such as a loan) with a lender that is a record or beneficial owner of more than 10% of an audit client’s equity securities. For purposes of the Loan Rule, audit clients include the registrant, as well as all registered investment companies advised by advisory subsidiaries of Federated Investors, Inc., the Adviser (for which EY serves as independent public accountant), and their respective affiliates (collectively, the “Federated Fund Complex”).

EY informed the Audit Committee that EY believes that these lending relationships described above do not and will not impair EY’s ability to exercise objective and impartial judgment in connection with the audits of the financial statements for the registrant and a reasonable investor with knowledge of all relevant facts and circumstances would conclude that EY has been and is capable of objective and impartial judgment on all issues encompassed within EY’s audits.

On June 20, 2016, the Division of Investment Management of the Securities and Exchange Commission (“SEC”) issued a no-action letter to another mutual fund complex (see Fidelity Management & Research Company et al., No-Action Letter) related to similar Loan Rule matters as those described above (the “Letter”). In the Letter, the SEC Staff confirmed that it would not recommend enforcement action against an investment company that relied on the audit services performed by an independent public accountant where the Loan Rule was implicated in certain specified circumstances provided that: (1) the auditor has complied with PCAOB Rule 3526(b)(1) and 3526(b)(2); (2) the Loan Rule is implicated because of lending relationships; and (3) notwithstanding such lending relationships that implicate the Loan Rule, the auditor has concluded that it is objective and impartial with respect to the issues encompassed within its engagement as auditor of the funds. The circumstances described in the Letter are substantially similar to the circumstances that implicated the Loan Rule with respect to EY and the registrant. On September 22, 2017, the SEC extended the expiration of the Letter until the effectiveness of any amendments to the Loan Rule designed to address the concerns in the Letter. On May 2, 2018, the SEC proposed amendments to the Loan Rule, which, if adopted as proposed, would refocus the analysis that must be conducted to determine whether an auditor is independent when the auditor has a lending relationship with certain shareholders of an audit client at any time during an audit or professional engagement period.

Additionally, on July 18, 2018, EY informed the registrant that Rule 2-01(c)(1)(i)(A) of Regulation S-X (“Investment Rule”) also has been implicated since July 2, 2018. The Investment Rule prohibits public accounting firms, or covered person professionals and their immediate family members, from having certain direct financial investments in their audit clients and affiliated entities. EY informed the registrant that a pension trust of a non-US affiliated entity of EY had previously made, and as of July 18, 2018 maintained, an investment in a fund (“Hermes Fund”) managed by Hermes Alternative Investment Management Limited (“HAIML”), which is a wholly owned subsidiary of Hermes Fund Managers Limited (“HFML”). The pension trust’s investment in the Hermes Fund involves the Investment Rule because an indirect wholly owned subsidiary of Federated Investors, Inc. (an affiliate of the registrant’s adviser), acquired a 60% majority interest in HFML on July 2, 2018, effective July 1, 2018 (“Hermes Acquisition”). The pension trust first invested in the Hermes Fund in 2007, well prior to the Hermes Acquisition. The pension trust’s investment represented less than 3.3% of the Hermes Fund’s assets as of July 18, 2018. EY subsequently informed the registrant that EY’s affiliated entity’s pension trust had submitted an irrevocable redemption notice to redeem its investment in the Hermes Fund. Pursuant to the redemption terms of the Hermes Fund, the pension trust’s redemption would not be effected until December 26, 2018 at the earliest. The redemption notice could not be revoked by the pension trust. The redemption notice would only be revoked by HAIML, as the adviser for Hermes Fund, if, and to the extent, the pension trust successfully sold its interest in the Hermes Fund in a secondary market transaction. EY also informed the registrant that the pension trust simultaneously submitted a request to HAIML to conduct a secondary market auction for the pension trust’s interests in the Hermes Fund. In addition, the only voting rights shareholders of the Hermes Fund had under the Hermes Fund’s governing documents relate to key appointments, including the election of the non-executive members of the Hermes Fund’s committee, the appointment of the Hermes Fund’s trustee and the adoption of the Hermes Fund’s financial statements. The next meeting of the Hermes Fund at which shareholders can vote on the election of members to the Hermes Fund’s committee is not until June 2019, and the size of the pension trust’s investment in the Hermes Fund would not allow it to unilaterally elect a committee member or the trustee. EY does not audit the Hermes Fund and the Hermes Fund’s assets and operations are not consolidated in the registrant’s financial statements that are subject to audit by EY. Finally, no member of EY’s audit team that provides audit services to the registrant is a beneficiary of EY’s affiliated entity’s pension trust. Management reviewed this matter with the registrant’s Audit Committee, and, based on that review, as well as a letter from EY to the registrant dated July 26, 2018, in which EY indicated that it had determined that this matter does not impair EY’s ability to exercise objective and impartial judgment in connection with the audit of the financial statements for the registrant and the belief that a reasonable investor with knowledge of all relevant facts and circumstances would conclude that EY has been and is capable of exercising objective and impartial judgment on all issues encompassed within EY’s audit, the registrant’s management and Audit Committee made a determination that such matter does not impair EY’s ability to exercise objective and impartial judgment in connection with the audit of the financial statements for the registrant. On August 29, 2018, EY informed the registrant that EY’s affiliated entity’s pension trust sold its entire interest in the Hermes Fund, effective as of August 29, 2018.

If it were to be determined that, with respect to the Loan Rule, the relief available under the Letter was improperly relied upon, or that the independence requirements under the federal securities laws were not complied with regarding the registrant, for certain periods, and/or given the implication of the Investment Rule for certain periods, any of the registrant’s filings with the SEC which contain financial statements of the registrant for such periods may be determined not to be consistent with or comply with applicable federal securities laws, the registrant’s ability to offer shares under its current registration statement may be impacted, and certain financial reporting and/or other covenants with, and representations and warranties to, the registrant’s lender under its committed line of credit may be impacted. Such events could have a material adverse effect on the registrant and the Federated Fund Complex.

(a) The registrant’s Schedule of Investments is included as part of the Report to Stockholders filed under Item 1 of this form.

(b) Not Applicable; Fund had no divestments during the reporting period covered since the previous Form N-CSR filing.

(b) There were no changes in the registrant’s internal control over financial reporting (as defined in rule 30a-3(d) under the Act) during the second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant’s internal control over financial reporting.
