The Funds are registered to offer different classes of shares: Class A shares, Class B shares, Class C shares, Class Y shares, and Institutional Class shares. The assets of each Fund are segregated, and a shareholder’s interest is limited to the Fund in which shares are held. The Funds’ prospectus provides a description of each Fund’s investment objectives, policies, and strategies along with information on the classes of shares currently being offered.

2. Significant Accounting Policies

The following is a summary of the Funds’ significant accounting policies:

Security valuation and fair value measurements — All investments in securities are recorded at their estimated fair value. The Funds use various methods to measure fair value of their portfolio securities on a recurring basis. U.S. GAAP establishes a hierarchy that prioritizes inputs to valuation methods. 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.)
• 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 necessarily an indication of the risk associated with investing in those securities. For example, money market instruments are valued using amortized cost, in accordance with rules under the 1940 Act. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected as Level 2. Transfers in and out of the levels are recognized at the value at the end of the period. During the period ended September 30, 2012, there were no transfers between Levels 1, 2 and 3.

The aggregate value by input level, as of September 30, 2012, for each Fund’s investments, as well as a reconciliation of assets for which significant unobservable inputs (Level 3) were used in determining value, if applicable, is included in each Fund’s Portfolio of Investments, which also includes a breakdown of the Fund’s investments by geographic/industry concentration. The Funds did not hold any Level 3 categorized securities during the six months ended September 30, 2012.

The Funds’ portfolio securities are valued as of the close of the regular session of trading on the New York Stock Exchange (currently 4:00 p.m., Eastern time). Portfolio securities traded on stock exchanges are valued

Notes to Financial Statements (Continued)

at the last sale price, and to the extent these securities are actively traded, they are categorized in Level 1 of the fair value hierarchy. Portfolio securities quoted by NASDAQ are valued at the NASDAQ Official Closing Price (“NOCP”). Securities not traded on a particular day, or for which the last sale price is not readily available, are valued at their last broker-quoted bid prices as obtained from one or more of the major market makers for such securities by an independent pricing service and are categorized in Level 2. While this method provides consistency in valuation (and may only be used if it approximates market value), it may result in periods during which value, as determined by amortized cost, is higher or lower than the price that would be received if the Fund sold the investment. Money market instruments and other debt securities with a remaining maturity of less than 60 days are valued at amortized cost, which approximates market value and are categorized in Level 2. Securities for which market quotations or the NOCP are not readily available are valued based on fair value as determined by or under the direction of the Board of Trustees and are categorized in Level 3. Shares of open end mutual funds in which the Funds invest are valued at their respective net asset values as reported by the underlying funds and are categorized in Level 1. The prices for foreign securities are reported in local currency and translated into to U.S. dollars using currency exchange rates.

For securities that principally trade on a foreign market or exchange, a significant gap in time can exist between the time of a particular security’s last trade and the time at which a Fund calculates its net asset value. The closing prices of such securities may no longer reflect their market value at the time the Fund calculates its net asset value if an event that could materially affect the value of those securities (a “Significant Event”) has occurred between the time of the security’s last close and the time that the Fund calculates its net asset value.

A Significant Event may relate to a single issuer or to an entire market sector. If the Advisor or Sub-Advisor of a Fund becomes aware of a Significant Event that has occurred with respect to a security or group of securities after the closing of the exchange or market on which the security or securities principally trade, but before the time at which the Fund calculates its net asset value, it may request that a Fair Value Committee Meeting be called. In addition, the Funds’ Administrator or Sub-Administrator monitors price movements among certain selected indices, securities and/or baskets of securities that may be an indicator that the closing prices received earlier from foreign exchanges or markets may not reflect market value at the time the Fund calculates its net asset value. If price movements in a monitored index or security exceed levels established by the Advisor, the Sub-Administrator notifies the Advisor or Sub-Advisor for any Fund holding the relevant securities that such limits have been exceeded. In such event, the Advisor makes the determination whether a Fair Value Committee meeting should be called based on the information provided. These securities are categorized in Level 2.

New accounting pronouncements — In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities (“ASU 2011-11”). ASU 2011-11 requires disclosures to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under IFRS. The new disclosure requirements mandate that entities disclose both gross and net information about instruments and transactions eligible for offset in the statement of assets and liabilities as well as instruments and transactions subject to an agreement similar to a master netting arrangement. In addition, ASU 2011-11 requires disclosure of collateral received and posted in connection with master netting agreements or similar arrangements. New disclosures are required for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is evaluating the impact of ASU 2011-11 on the financial statements and disclosures.

In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in GAAP and the International Financial Reporting Standards (IFRS).” ASU 2011-04 includes common requirements for measurement of and disclosure about fair value between U.S. GAAP and IFRS. ASU 2011-04 will require reporting entities to categorize within Level 3 of the fair value hierarchy: quantitative information about the unobservable inputs used in the fair value measurement; the valuation processes used by the reporting entity;

Notes to Financial Statements (Continued)

and a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs. In addition, ASU 2011-04 will require reporting entities to make disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. The new and revised disclosures are effective for fiscal years beginning after December 15, 2011 and for interim periods within those fiscal years.

Foreign currency translation — The books and records of the Funds are maintained in U.S. dollars and translated into U.S. dollars on the following basis:

(1)

market value of investment securities, assets and liabilities at the current rate of exchange on the valuation date; and

(2)

purchases and sales of investment securities, income and expenses at the relevant rates of exchange prevailing on the respective dates of such transactions.

The Funds do not isolate that portion of gains and losses on investments in equity securities that is due to changes in the foreign exchange rates from that which is due to changes in market prices of equity securities.

Portfolio securities loaned — Each Fund may lend its portfolio securities. Lending portfolio securities exposes a Fund to the risk that the borrower may fail to return the loaned securities or may not be able to provide additional collateral or that the Fund may experience delays in recovery of the loaned securities or loss of rights in the collateral if the borrower fails financially. To minimize these risks, the borrower must agree to maintain cash collateral with the Funds’ custodian in an amount at least equal to the market value of the loaned securities. The loaned securities are secured by collateral valued at least equal, at all times, to the fair value of the securities loaned plus accrued interest. When the collateral falls below specified amounts, the lending agent will use its best effort to obtain additional collateral on the next business day to meet required amounts under the security lending agreement. The cash collateral is reinvested by the Funds’ custodian into an approved investment vehicle.

As of September 30, 2012, the following Funds loaned securities and received collateral as follows:

		Fair Value of		Value of
		Securities		Collateral
Fund		Loaned		Received
Diversified Small Cap Growth Fund	$	2,615,068	$	2,684,106
Growth Opportunities Fund		1,252,979		1,281,105

All collateral received as cash is received, held and administered by the Funds’ custodian for the benefit of the Funds in the applicable custody account or other account established for the purpose of holding collateral.

Funds participating in securities lending receive compensation in the form of fees, or retain a portion of interest or dividends on the investment of any cash received as collateral. The Funds also continue to receive interest or dividends on the securities loaned.

Unrealized gain or loss on the fair value of the securities loaned that may occur during the term of the loan is recognized by the Funds. The Funds have the right under the lending agreement to recover the securities from the borrower on demand.

Share valuation — The net asset value per share of each class of shares of each Fund is calculated daily by dividing the total value of a Fund’s assets attributable to that class, less liabilities attributable to that class, by the number of outstanding shares of that class.

The maximum offering price per share of Class A shares of the Funds is equal to the net asset value per share plus a sales load equal to 6.10% of the net asset value (or 5.75% of the offering price). There is no sales load

Notes to Financial Statements (Continued)

on purchases of $1 million or more of Class A Shares. The maximum offering price per share of Class B, Class C, Class Y, and Institutional Class shares of the Funds is equal to the net asset value per share.

The redemption price per share of each class of shares of the Funds is generally equal to the net asset value per share. However, Class A redemptions that were part of a no load $1 million subscription may be subject to a contingent deferred sales charge (“CDSC”) of up to 1%. Class B shares of the Funds are subject to a contingent deferred sales load of 5.00% in the event of a shareholder redemption within a one-year period of purchase. The contingent deferred sales load will be incrementally reduced over time. After the 6th year, there is no contingent deferred sales load. Class C shares of the Funds are subject to a contingent deferred sales load of 1.00% of the original purchase price if redeemed within a one-year period from the date of purchase.

Investment income — Dividend income from securities is recognized on the ex-dividend date, net of foreign withholding taxes, if any, which are reduced by any amounts reclaimable by the Funds, where applicable. Interest income from securities is recorded on the basis of interest accrued, premium amortized and discount accreted.

Distributions to shareholders — Each Fund declares and distributes net investment income, if any, annually, as a dividend to shareholders. Any net realized capital gains on sales of securities for all Funds are distributed to shareholders at least annually. Income distributions and capital gain distributions are determined in accordance with income tax regulations.

Allocations — Investment income earned, realized capital gains and losses, and unrealized appreciation and depreciation for the Funds are allocated daily to each class of shares based upon its proportionate share of total net assets of the Fund. Class specific expenses are charged directly to the class incurring the expense. Common expenses, which are not attributable to a specific class, are allocated daily to each class of shares based upon their proportionate share of total net assets of the Fund. Expenses not directly billed to a Fund are allocated proportionally among all Funds daily in relation to net assets of each Fund or another reasonable measure.

Security transactions — Security transactions are reflected for financial reporting purposes as of the trade date, which may cause the net asset value (“NAV”) as stated in the accompanying financial statements to be different than the NAV applied to Fund share transactions. Realized gains and losses on sales of portfolio securities are calculated using the identified cost basis.

Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

5. Federal Tax Information

Federal income tax — It is each Fund’s policy to continue to comply with the special provisions of the Internal Revenue Code applicable to regulated investment companies. As provided therein, in any fiscal year in which a Fund so qualifies and distributes at least 90% of its investment company taxable income, the Fund (but not the shareholders) will be relieved of federal income tax on the income distributed. Accordingly, no provision for income taxes has been made.

In order to avoid imposition of the excise tax applicable to regulated investment companies, it is also each Fund’s intention to declare and pay as dividends in each calendar year at least 98% of its investment company taxable income (earned during the calendar year) and 98.2% of its net realized capital gains (earned during the twelve months ending October 31) plus undistributed amounts from prior years.

The tax character of distributions paid for the years ended March 31, 2012 and 2011 was as follows:

The difference between the tax cost of portfolio investments and the financial statement cost is primarily due to wash sale loss deferrals.

As of March 31, 2012, the Funds had the following capital loss carryforwards for federal income tax purposes:

		2013		2014		2016			2017			2018			Total
Diversified Small Cap Growth Fund	$	—	$	4,602,156	$	3,627,106		$	5,932,361		$	—		$	14,161,623

* Amount may be limited by current income tax regulations.

The capital loss carryforwards may be utilized in future years to offset net realized capital gains, if any, prior to distributing such gains to shareholders.

As of September 30, 2012, the Trust had the following federal tax cost resulting in net unrealized appreciation (depreciation) as follows:

Fund		Federal Tax Cost		Gross Unrealized Appreciation		Gross Unrealized Depreciation			Net Unrealized Appreciation (Depreciation)
Diversified Small Cap Growth Fund	$	29,236,755	$	5,200,409	$	(1,384,236	)	$	3,816,173
Growth Opportunities Fund		174,603,437		13,180,225		(3,548,146	)		9,632,079
Large Cap Growth Fund		813,550,120		170,434,268		(6,546,906	)		163,887,362
Mid Cap Growth Fund		568,183,535		76,262,976		(15,776,955	)		60,486,021

The Funds have analyzed their tax positions taken on Federal income tax returns for all open tax years (tax years ended March 31, 2008 through 2011) and have concluded that no provision for income tax is required in their financial statements.

The Regulated Investment Company Modernization Act of 2010 (the “Act”) was enacted on December 22, 2010. The Act makes changes to several tax rules impacting the Funds. In general, the provisions of the Act will be effective for the Funds’ fiscal year ending September 30, 2012. Although the Act provides several benefits, including the unlimited carryover of future capital losses, there may be a greater likelihood that all or a portion of each fund’s pre-enactment capital loss carryovers may expire without being utilized due to the fact that post-enactment capital losses must be utilized before pre-enactment capital loss carryovers. Under the Act, new capital losses may now be carried forward indefinitely, and retain the character of the original loss as compared with pre-enactment law, where capital losses could be carried forward for eight years, and carried forward as short-term capital losses, irrespective of the character of the original loss.

Notes to Financial Statements (Continued)

6. Commitments and Contingencies

The Funds indemnify the Trust’s officers and Trustees for certain liabilities that might arise from their performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote.

Notes to Financial Statements (Continued)

At a meeting held on March 13, 2012, the Board of Trustees of the Trust approved an Agreement and Plans of Reorganization (the “Plans”) providing for the transfer of all assets and liabilities of the Fifth Third Mid Cap Growth Fund and the Fifth Third Quality Growth Fund (each an “Acquired Fund”), each a series of Fifth Third Funds (“Fifth Third”), to the Touchstone Growth Opportunities Fund and the Touchstone Large Cap Growth Fund(each an “Acquiring Fund”), respectively. The mergers took place on September 10, 2012.

*	The Acquired Funds had Class B shares and Institutional Class shares outstanding immediately prior to the reorganization, which were exchanged for Class A shares and Class Y shares, respectively, of the Acquiring Funds.

Assuming the reorganization had been completed on April 1, 2012, the results of operations for the Growth Opportunities Fund and the Large Cap Growth Fund for the six months ended September 30, 2012 would have been as follows:

		Touchstone Growth Opportunities Fund			Touchstone Large Cap Growth Fund
Net investment income (loss)	$	(308,748	)	$	734,519
Net realized and unrealized gain (loss) on investments	$	15,219,727		$	73,269,865
Net increase in asset from operations	$	14,910,979		$	74,004,384

Because the combined investment portfolios have been managed as single portfolios since the Reorganizations were completed, it is not practical to separate the amounts of revenue and earnings to the Acquiring Funds that have been included in their statements of operations since the mergers.

8. Subsequent Events

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were issued, and has determined that there were no subsequent events.

Other Items (Unaudited)

Proxy Voting Guidelines

The Sub-Advisors are responsible for exercising the voting rights associated with the securities purchased and held by the Funds. A description of the policies and procedures that the Sub-Advisors use in fulfilling this responsibility and information regarding how those proxies were voted during the twelve month period ended June 30 are available without charge upon request by calling toll free 1.800.543.0407. These items are also available on the Securities and Exchange Commission’s (the Commission) website at http://www.sec.gov.

Quarterly Portfolio Disclosure

The Trust files a complete listing of portfolio holdings for each Fund as of the end of the first and third quarters of each fiscal year on Form N-Q. The complete listing: (i) is available on the Commission’s website; (ii) may be reviewed and copied at the Commission’s Public Reference Room in Washington, DC; and (iii) will be made available to shareholders upon request by calling 1.800.543.0407. Information on the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330.

Schedule of Shareholder Expenses

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs, including reinvested dividends or other distributions; and (2) ongoing costs, including investment advisory fees, shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period April 1, 2012 through September 30, 2012.

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid 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 line under the heading entitled “Expenses Paid During the Six Months Ended September 30, 2012” to estimate the expenses you paid on your account during this period.

Schedule of Shareholder Expenses (Continued)

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Funds’ actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds’ actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and 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.
