YEAR IN REVIEW
 
The U.S. investment market's performance in 1995 was nothing short of
extraordinary. We have seen some of the best market returns in years for both
equity and fixed income instruments. But on the short-term yield front, 1995
was a mixed year. Through the first six months of 1995, yields continued to
rise and most expected the average taxable yield to close in on 6.0%. However,
the slowdown in economic growth, coupled with low inflation prompted the
Federal Reserve to change its course and lower the Fed Funds rate, first in
July and again in December. As of December 31, 1995, the Fed Funds rate stood
at 5.50%.
 
INTEREST RATE OUTLOOK
 
The Federal Reserve is expected to continue to ease interest rates at a
gradual pace in 1996. This should occur primarily in the first part of the
year. The slant of monetary policy reflects a growing consensus at the Fed
that economic growth can be stronger (and the unemployment rate lower) without
igniting inflation. Our forecast is for the Fed Funds rate to fall to 4 3/4%
by the end of 1996. Relatively moderate economic growth and benign inflation,
along with the Fed easing credit, are also expected to keep long-term bond
rates low.
 
TRIPLE "A" RATING
 
As of December 31, 1995, the Prairie Cash Management Fund, Prairie U.S.
Government Securities Cash Management Fund and Prairie Treasury Prime Cash
Management Fund were each assigned a "AAA" rating by Standard & Poor's Ratings
Group and a "Aaa" rating by Moody's Investors Service, Inc. These ratings
reflect the Funds' capacity to maintain principal value and limit exposure to
loss.
 
We thank you for the confidence that you have expressed in us by investing in
the Prairie Institutional Funds. We will continue to earn your trust by
pursuing an investment strategy which seeks to provide competitive yields
consistent with protecting the value of your principal.
 
Sincerely,

An investment in the Funds is neither insured nor guaranteed by the U.S.
Government. Yields will fluctuate, and there can be no assurance that the
Funds will be able to maintain a stable NAV of $1.00 per share.
 
Portions of the advisory fee, the administration fee and other expenses
payable by the Funds are being reimbursed. If fees had not been reimbursed,
the yields shown above would have been 5.35% and 5.09%, respectively, for the
Prairie Cash Management Fund, 5.22% and 4.93% for the Prairie U.S. Government
Securities Cash Management Fund and 4.81% and 4.56% for the Prairie Treasury
Prime Cash Management Fund. The fee reimbursement is voluntary and may be
terminated or modified at any time which would reduce fund performance.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--GENERAL
 
  Prairie Institutional Funds (the "Trust") is registered under the Investment
Company Act of 1940, as amended, (the "Act") as an open-end management
investment company. At December 31, 1995, the Trust was comprised of four
separate investment portfolios as follows: Cash Management Fund, Municipal
Cash Management Fund, Treasury Prime Cash Management Fund and U.S. Government
Securities Cash Management Fund. The accompanying financial statements relate
only to the Cash Management Fund, Treasury Prime Cash Management Fund and U.S.
Government Securities Cash Management Fund (collectively, the "Funds"). As of
December 31, 1995, the Municipal Cash Management Fund had not yet commenced
operations.
 
  The Funds each offer two classes of shares, Institutional Shares and Service
Shares. Institutional Shares and Service Shares are substantially the same
except that Service Shares are subject to fees payable under a Service Plan
adopted pursuant to Rule 12b-1 under the Act (the "Service Plan") at an annual
rate of 0.25% of the average daily net asset value of the outstanding Service
Shares.
 
  At a shareholder meeting of the First Prairie U.S. Treasury Securities Cash
Management Fund (the "Treasury Predecessor Fund") held on December 21, 1994,
the shareholders approved an Agreement and Plan of Exchange pursuant to which
the Treasury Predecessor Fund transferred all of its assets and liabilities to
the U.S. Government Securities Cash Management Fund. In exchange for the
assets and liabilities, the U.S. Government Securities Cash Management Fund
issued Institutional Shares to the shareholders of the Treasury Predecessor
Fund equal in value to shares held by such shareholders immediately prior to
the exchange. This exchange took place on January 17, 1995, at which time the
shareholders of the Treasury Predecessor Fund received a pro rata distribution
of 431,159,110 Institutional Shares of the U.S. Government Securities Cash
Management Fund having a net asset value of $430,731,675.
 
  At a shareholder meeting of First Prairie Cash Management Fund (the
"Predecessor Fund") held on December 21, 1994, the shareholders approved an
Agreement and Plan of Exchange pursuant to which the Predecessor Fund
transferred all of its assets and liabilities to the Cash Management Fund. In
exchange for the assets and liabilities, the Cash Management Fund issued
Institutional Shares to the shareholders of the Predecessor Fund equal in
value to shares held by such shareholders immediately prior to the exchange.
This exchange took place on January 17, 1995 at which time the shareholders of
the Predecessor Fund received a pro rata distribution of 263,124,343
Institutional Shares of the Cash Management Fund having a net asset value of
$262,954,610.
 
  First Chicago Investment Management Company ("FCIMCO"), a wholly-owned
subsidiary of The First National Bank of Chicago ("FNBC"), serves as each
Fund's investment adviser and administrator. FCIMCO has engaged Concord
Holding Corporation ("Concord"), a wholly-owned subsidiary of The BISYS Group,
Inc. ("BISYS"), to serve as the Funds' sub-administrator. Concord Financial
Group, Inc., a wholly-owned subsidiary of BISYS, serves as the principal
underwriter and distributor of each Fund's shares.
 
NOTE 2--SIGNIFICANT ACCOUNTING POLICIES
 
  The following is a summary of significant accounting policies followed by
the Trust in the preparation of its financial statements. The policies are in
conformity with generally accepted accounting principles. These principles
require management to make estimates and assumptions that affect the reported
amounts of assets and
 
                                      12

PRAIRIE INSTITUTIONAL FUNDS

NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
- -------------------------------------------------------------------------------
 
liabilities at the date of the financial statements and the reported amounts
of income and expenses for the period. Actual results could differ from those
estimates.
 
  (a) Portfolio Valuation: Investments of the Funds are valued at either
amortized cost, which approximates market value. Under the amortized cost
method, discount or premium is amortized on a constant basis to the maturity
of the security. In addition, the Funds generally may not (a) purchase any
instrument with a remaining maturity greater than thirteen months unless such
instrument is subject to a demand feature, or (b) maintain a dollar-weighted
average maturity which exceeds 90 days.
 
  (b) Securities transactions and investment income: Securities transactions
are recorded on a trade date basis. Realized gains and losses from securities
transactions are recorded on the identified cost basis. Interest income,
adjusted for amortization of premiums and when appropriate, discounts on
investments, is earned from settlement date and recognized on the accrual
basis.
 
  The U.S. Government Securities Cash Management Fund and Cash Management Fund
may enter into repurchase agreements with financial institutions deemed to be
creditworthy by FCIMCO, subject to the seller's agreement to repurchase and
the Fund's agreement to resell such securities at a mutually agreed upon
price. Securities purchased subject to repurchase agreements are deposited
with the Fund's custodian and, pursuant to the terms of the purchase
agreement, must have an aggregate market value greater than or equal to the
repurchase price plus accrued interest at all times. If the value of the
underlying securities falls below the value of the repurchase price plus
accrued interest, the Fund will require the seller to deposit additional
collateral by the next business day. If the request for additional collateral
is not met, or the seller defaults on its purchase obligation, the Fund
maintains the right to sell the underlying securities at market value and may
claim any resulting loss against the seller.
 
  (c) Dividends to shareholders: Each Fund's dividends from net investment
income are declared daily and paid monthly. Distributions from net realized
capital gains, if any, are normally declared annually and paid annually, but
each Fund may make distributions on a more frequent basis to comply with the
distribution requirements of the Internal Revenue Code (the "Code"). To the
extent that net realized capital gains can be offset by capital loss
carryovers, it is the policy of each Fund not to distribute such gains.
 
  (d) Federal income taxes: It is the policy of each Fund to continue to
qualify as a regulated investment company by complying with the provisions
available to certain investment companies, as defined in applicable sections
of the Code, and to make distributions of taxable income sufficient to relieve
it from all, or substantially all, Federal income taxes. At December 31, 1995,
the U.S. Government Securities Cash Management Fund had unused capital loss
carryovers of approximately $525,000, which are available for Federal income
tax purposes to be applied against future net capital gains, if any, realized
subsequent to December 31, 1995. If not applied, $7,000 of the carryover

NOTE 4--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFIILIATES
 
  (a) The Trust has an Investment Advisory Agreement with FCIMCO pursuant to

Fund's investments for an advisory fee at an annual rate of 0.20% of each
Fund's average daily net assets.
 
  The Trust has an Administration Agreement with FCIMCO pursuant to which
FCIMCO has agreed to assist in all aspects of each Fund's operations for an
administration fee at an annual rate of 0.15% of each Fund's average daily net
assets. In addition, FCIMCO has engaged Concord to assist in providing certain
administrative services to each Fund pursuant to a Master Sub-Administration
Agreement between FCIMCO and Concord. FCIMCO has agreed to pay Concord a fee
from its own administration fee on a monthly basis.
 
  For the period June 1, 1995 through December 31, 1995 for the U.S.

  (b) The Trust has adopted a Service Plan pursuant to Rule 12b-1 under the
Act. Under the terms of the Service Plan, each Fund pays the Distributor an
annual fee of 0.25% of the average daily net assets of the outstanding Service
Shares for advertising, marketing and distributing each Fund's Service Shares
and for the provision of certain services to the holders of Service Shares.
The Distributor may make payments to others, including FCIMCO, FNBC and their
affiliates, for the provision of these services. For the period June 1, 1995
through December 31, 1995, the U.S. Government Securities Cash Management Fund
paid fees under the Service Plan in the amount of $56,289. For the period
March 22, 1995 (commencement of operations) through December 31, 1995, the

amount of $38,892. For the period July 1, 1995 (initial offering of Service
Shares) through December 31, 1995, the Cash Management Fund paid fees under
the Service Plan in the amount of $73,857. Of these amounts, the following was
paid to the Distributor and FCIMCO and its affiliates:

  (c) The Fund's pay each Trustee a pro-rata share of the aggregate fixed
annual fee of $25,000 and an attendance fee of $1,000 per meeting for all of
the Funds in the Prairie Family of Funds.
 
  (d) During the year ended June 30, 1995, an affiliate of FCIMCO purchased
securities from the Cash Management Fund at an amount in excess of the
securities' fair market value. The Cash Management Fund recorded a realized
loss on these sales in the amount of $1,668,500 and the Cash Management Fund
recorded an offsetting capital contribution from the affiliate. As a result of
varying treatment for book and tax purposes, the capital contribution was
reclassified from additional paid-in-capital to accumulated net realized
losses in the Statement of Assets and Liabilities.
 
NOTE 5--MERGER AND SUBSEQUENT EVENT
 
  On December 1, 1995, FCIMCO's ultimate parent company, First Chicago
Corporation, merged with NBD Bancorp, Inc., with the combined company renamed
First Chicago NBD Corporation (FCNBD). FCNBD has now begun the process of
reorganizing their proprietary mutual funds: Prairie Funds, Prairie
Institutional Funds and The Woodward Funds (whose investment adviser is NBD
Bank, a wholly owned subsidiary of NBD Bancorp, Inc., which in turn is a
wholly owned subsidiary of FCNBD).
 
  On February 20, 1996, the Board of Trustees of The Woodward Funds and the
Board of Trustees of Prairie Funds and Prairie Institutional Funds approved
Reorganization Agreements which are subject to shareholder approval. The
expenses incurred in connection with entering into and carrying out provisions
of the Reorganization Agreements, whether or not the transactions contemplated
thereby are consummated, will be paid by FCNBD. The reorganization is intended
to be effected on a tax-free basis, so that none of the Fund's shareholders
will recognize taxable gains or losses as a result of the reorganization.
 
  A proxy statement/prospectus describing the reorganization and the reasons
therefore will be sent to shareholders.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT AUDITORS
- -------------------------------------------------------------------------------
 
PRAIRIE INSTITUTIONAL FUNDS THE BOARD OF TRUSTEES AND SHAREHOLDERS
 
  We have audited the accompanying statements of asset and liabilities,
including the portfolios of investments, of Prairie Institutional Funds
(comprising, respectively, the U.S. Government Securities Cash Managment,
Treasury Prime Cash Management and Cash Management Funds) (the "Fund") as of
December 31, 1995 and the related statements of operations for the periods
then ended, and the statements of changes in net assets and the financial
highlights for each of the periods indicated therein. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of investments
owned as of December 31, 1995 by correspondence with the custodians and
others. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
  In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective funds constituting the Prairie Institutional Funds at
December 31, 1995, the results of their operations for the periods then ended,
and the changes in their net assets and the financial highlights for each of
the indicated periods, in conformity with generally accepted accounting
principles.
