1. ORGANIZATION

The Touchstone Institutional Funds Trust (the Trust), a Delaware Business Trust,
is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company with two funds. The financial statements
included herein are those of the Touchstone Mazama Institutional Growth Fund,
which is a diversified fund, and Touchstone Sands Capital Institutional Growth
Fund, which is a non-diversified fund (each individually a "Fund" and
collectively the "Funds"). The Funds commenced operations on January 30, 2008
and January 21, 2005, respectively.

The Funds are registered to offer one class of 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
class of shares currently being offered.

2. SIGNIFICANT ACCOUNTING POLICIES

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

SECURITY VALUATION -- 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
at the last sale price and 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. 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. 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. 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.

The Funds have adopted FASB ASC 820 "Fair Value Measurements." This standard
establishes a single authoritative definition of fair value, sets out a
framework for measuring fair value and requires additional disclosures about
fair value measurements. Fair Value Measurements applies to fair value
measurements already required or permitted by existing standards. The changes to
current generally accepted accounting principles (GAAP) from the application of
this Statement relate to the definition of fair value, the methods used to
measure fair value, and the expanded disclosures about fair value measurements.

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

o Level 1 -- quoted prices in active markets for identical securities

o Level 2 -- other significant observable inputs (including quoted prices for
             similar securities, interest rates, prepayment speeds, credit risk,
             etc.)

o 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 securities are valued using amortized cost, in accordance
with rules under the Investment Company Act of 1940. 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.


                                       10


- --------------------------------------------------------------------------------
Notes to Financial Statements (Continued)
- --------------------------------------------------------------------------------

The aggregate value by input level, as of June 30, 2010, for each Fund's
investments, is included in each Fund's Portfolio of Investments, which also
includes a breakdown of the Fund's investments by geographic/industry
concentration.

NEW ACCOUNTING PRONOUNCEMENTS -- In January 2010, the Financial Accounting
Standards Board ("FASB") issued new guidance as an amendment to fair value
measurements and disclosures. The new guidance adds new requirements for
disclosure about transfers into and out of level 1 and level 2 fair value
measurements and separate disclosures about purchases, sales, issuances, and
settlements relating to level 3 measurements. The guidance also clarifies
existing fair value disclosures about the level of disaggregation and about
inputs and valuation techniques in level 2 and level 3 fair value measurements.
The amendment is effective for interim and annual reporting periods beginning
after December 15, 2009, except for Level 3 reconciliation disclosures which are
effective for interim and annual periods beginning after December 15, 2010. The
Funds do not expect the implications of this guidance to have a material impact
on its financial statements.

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
collateral marked to market daily, in the form of cash and/or liquid securities,
with the Fund's custodian in an amount at least equal to the market value of the
loaned securities.

As of June 30, 2010, the following Funds loaned common stocks and received
collateral as follows:

                                                  MARKET VALUE      VALUE OF
                                                    OF COMMON      COLLATERAL
                                                  STOCKS LOANED     RECEIVED
- --------------------------------------------------------------------------------
Touchstone Mazama Institutional Growth Fund       $   1,537,611   $   1,583,376

All collateral received as cash and securities 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. The loans are secured by collateral valued at least
equal, at all times, to the fair value of the securities loaned plus accrued
interest. Unrealized gain or loss on the fair value of the securities loaned
that may occur during the term of the loan are 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 is calculated each business
day. It is computed by dividing the assets of each Fund, less its liabilities,
by the number of outstanding shares of each Fund.

SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME -- Security transactions are
accounted for on the date the security is purchased or sold (trade date).
Dividend income is recognized on the ex-dividend date. Costs used in determining
realized gains and losses on the sales of investment securities are those of the
specific securities sold.

- --------------------------------------------------------------------------------
Notes to Financial Statements (Continued)
- --------------------------------------------------------------------------------

DIVIDENDS AND DISTRIBUTIONS -- The Funds pay distributions of net income
quarterly. Any net realized capital gains on sales of securities are distributed
to shareholders at least annually.

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 reported period. Actual results could
differ from those estimates.

EXPENSES -- The Funds pay a unified management fee to Touchstone Advisors, Inc.
(the Advisor) for providing or procuring advisory, administration and other
services. The Advisor is responsible for compensating any third party engaged to
provide services under its supervision and is also responsible for payment of
the fees of the independent Trustees, custodian, independent auditor, legal
counsel (excluding costs in connection with certain litigation or administrative
actions), and the transfer and dividend disbursing agent. The Funds will pay all
state registration fees and charges incurred related to printing and mailing to
existing shareholders prospectuses, statement of additional information, proxy
solicitation material, shareholder reports and EDGAR filings.

6. FEDERAL INCOME TAXES

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 taxable net 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 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 December 31, 2009
and 2008 was as follows:

Notes to Financial Statements (Continued)
- --------------------------------------------------------------------------------

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

Certain reclassifications, the result of permanent differences between financial
statement and income tax reporting requirements have been made to the components
of capital. These reclassifications have no impact on the net assets or net
asset value per share of the Funds and are designed to present the Funds'
capital accounts on a tax basis. The following reclassifications of return of
capital distributions, investments in limited partnerships and net investment
loss have been made to the following Funds for the year ended December 31, 2009:



                                                                         UNDISTRIBUTED    ACCUMULATED

The Funds have analyzed their tax positions taken on Federal income tax returns
for all open tax years (tax years ended December 31, 2006 through 2009) and have
concluded that no provision for income tax is required in their financial
statements.

7. 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.

8. CONCENTRATIONS/RISKS

Each Fund may invest a high percentage of its assets in specific sectors of the
market in order to achieve a potentially greater investment return. As a result,
the Funds may be more susceptible to economic, political, and regulatory
developments in a particular sector of the market, positive or negative, and may
experience increased volatility on the Funds' net asset value and magnified
effect on the total return.

9. SUBSEQUENT EVENTS

During a meeting held August 19, 2010 of the Board of Trustees, the Trustees
unanimously approved the liquidation of the Mazama Institutional Growth Fund.

PROXY VOTING

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; distribution (12b-1) 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 (January 1, 2010 through June 30, 2010).

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 June 30, 2010" to estimate the expenses you paid on your account
during this period.

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.
