AHA INVESTMENT FUNDS, INC.
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1997
(UNAUDITED)

NOTE 1.
SIGNIFICANT ACCOUNTING POLICIES
The following are the significant accounting policies of Full Maturity Fixed
Income, Limited Maturity Fixed Income, Diversified Equity and Balanced
Portfolios (the "Portfolios"), each a series of AHA Investment Funds, Inc., a
Maryland corporation, ("Fund").

SECURITY VALUATIONS
All securities are recorded at fair market value as of December 31, 1997. 
Securities traded on national securities exchanges are valued at last 
reported sales prices or, if there are no sales, at the latest bid quotation. 
Each over-the-counter security for which the last sale price is available 
from NASDAQ is valued at that price. All other over-the-counter securities 
for which reliable quotations are available are valued at the latest bid 
quotation. Securities convertible into equity securities are valued at the 
greater of latest bid valuation or net conversion value. Other assets and 
securities are valued by a method that the Board of Directors believes 
represents a fair value.

ACCOUNTING FOR FUTURES
The Fund may enter into long or short positions in futures contracts in order to
hedge against the effect of changing values on portfolio securities held. When
the Fund enters into a futures contract, it is required to deposit, into a
segregated account at its custodian bank, U.S. Government securities as a
guarantee that it will meet the futures commitment. Each day the Fund receives
or pays cash, called "variation margin", equal to the daily change in the market
value of the futures contracts. Such receipts and payments are recorded as
unrealized gains or losses until the futures contracts expire or are closed out.
Risks of entering into futures contracts include the possibility that there may
be an illiquid market at the time the Portfolios seek to close out a contract
and changes in the value of the futures contract may not correlate with changes
in the value of the portfolio securities being hedged. The Full Maturity Fixed
Income and Balanced Portfolios had open futures contracts as of December 31,
1997.

ACCOUNTING FOR OPTIONS
The Fund may purchase and write (sell) put and call options on U.S. securities,
stock indices, and futures contracts that are traded on U.S. securities
exchanges and over-the-counter markets. The risk associated with purchasing an
option is that the Fund pays a premium whether or not the option is exercised.
Additionally, the Fund bears the risk of loss of premium and change in market
value should the counterparty not perform under the contract. Put and call
options purchased are accounted for in the same manner as portfolio securities.
The cost of securities acquired through the exercise of call options is
increased by premiums paid. The proceeds from securities sold through the
exercise of put options are decreased by the premiums paid.
- -------------------------------------------------------------------------------
                                          37

<PAGE>

When the Fund writes an option, the premium received by the Fund is recorded as
a liability and is subsequently adjusted to the current market value of the
option written. Premiums received from writing options which expire unexercised
are recorded by the Fund on the expiration date as realized gains from option
transactions. The difference between the premium and the amount paid on
effecting a close purchase transaction, including brokerage commissions, is also
treated as a realized gain, or if the premium is less than the amount paid for
the closing purchase transaction, as a realized loss. If a call option is
exercised, the premium is added to the proceeds from the sale of the underlying
security or currency in determining whether the Fund has realized a gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
security or currency purchased by the Fund. In writing an option, the Fund bears
the market risk of an unfavorable change in the price of the security or
currency underlying the written option. Exercise of an option written by the
Fund could result in the Fund selling or buying a security or currency at a
price different from the current market value. Transactions in put options
written for the six months ended December 31, 1997 for the Fund were as follows:

INVESTMENTS OBJECTIVES
FULL MATURITY FIXED INCOME PORTFOLIO
Seeks over the long term the highest level of income consistent with
preservation of capital. Invests primarily in high quality fixed income
securities. There is no restriction on the maximum maturity of the securities
purchased. The average dollar-weighted maturity will vary and may exceed 20
years.

LIMITED MATURITY FIXED INCOME PORTFOLIO
Seeks a high level of current income, consistent with preservation of capital
and liquidity. Invests primarily in high quality fixed income securities and
maintains an average dollar-weighted portfolio maturity of five years or less.

DIVERSIFIED EQUITY PORTFOLIO
Seeks long-term capital growth. Invests primarily in equity securities and
securities having equity characteristics.

BALANCED PORTFOLIO
Seeks a combination of growth of capital and income. Invests varying proportions
of its assets in equity and fixed income securities, with not less than 25
percent of total assets invested in fixed income securities.

REPURCHASE AGREEMENTS
The Fund may enter into repurchase agreements with respect to any of the types
of securities in which they are authorized to invest without regard to the
maturity of the underlying security. Repurchase agreements will be effected only
with banks, savings institutions and broker-dealers. They involve the purchase
by a Portfolio of a debt security with the condition that, after a stated period
of time, the original seller will buy back the same security at a predetermined
price or yield. Repurchase agreements are used to enhance liquidity and to earn
income for periods as short as overnight. To minimize risk, the securities
underlying each repurchase agreement will be maintained with the Fund's
custodian, or a subcustodian, in an amount at least equal in value to the
repurchase price under the agreement (including accrued interest thereunder),
and such agreements will only be effected with parties that meet certain
creditworthiness standards. However, in the event the other party to the
repurchase agreement fails to repurchase the securities subject to such
agreement, a Portfolio could suffer a loss to the extent it is precluded from
selling the securities or, if due to delays, proceeds from the sale are less
than the repurchase price. The Fund had no outstanding repurchase agreements as
of December 31, 1997.

FEDERAL INCOME TAXES
No provision is made for Federal Income Taxes since the Portfolios elect to be
taxed as "regulated investment companies" and make such distributions to their
shareholders as to be relieved of all Federal income taxes under provisions of
current Federal tax law. At June 30, 1997, the Fund' most recent fiscal year
end, the approximate capital loss carryforwards for U.S. Federal income tax
purposes for the Full Maturity Fixed Income Portfolio and the Limited Maturity
Fixed Income Portfolio were approximately $1,800,000 and $3,700,000
respectively. This capital loss carryforward expires beginning in the year
ending June 30, 2003 and is available to offset future capital gains.

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles 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 increases and decreases in net assets from operations
during the reporting period. Actual results could differ from those estimates.

OTHER INFORMATION

NOTE 3.
DIRECTORS' FEES AND TRANSACTIONS WITH AFFILIATES
Directors not affiliated with Hewitt Associates LLC ("Hewitt") or American
Hospital Association ("AHA") receive $1,000 for each quarterly meeting and $500
for each special meeting from the Board of Directors, or committee thereof,
(plus travel expenses). No remuneration has been paid to any principal or
employee of the Fund's investment consultant, Hewitt, or any director or officer
of AHA. The investments of the Portfolios are managed by various advisory
organizations which serve as the investment managers. The Fund pays no fees to
Hewitt or to the investment managers.

Hewitt is compensated for its services by the shareholders pursuant to The
Program Services Agreement it has with each shareholder, under which Hewitt
Provides asset allocation consulting and certain other services. Fees of the
investment managers are paid by Hewitt.

Hewitt has voluntarily undertaken to pay certain expenses of the Portfolios (or
to reimburse the Portfolios for certain expenses) as may be necessary to limit
total expenses of the Portfolios to specified amounts. American Hospital
Association Services, Inc. has, in this regard, agreed to reimburse Hewitt for
one-half of the amounts incurred by Hewitt pursuant to this undertaking. The
maximum expense as a percent of average net assets for the Full Maturity Fixed
Income Portfolio, the Limited Maturity Fixed Income Portfolio, the Diversified
Equity Portfolio, and the Balanced Portfolio is 0.50% (annual percentage). The
Portfolios have reached asset levels which allow the reduction of expenses to
percentage amounts below that set forth above. The Portfolios may reimburse
Hewitt for the expenses of the Portfolios it voluntarily has absorbed on or
after September 1, 1989, provided that such reimbursement does not cause the
percentage expense limitations set forth above to be exceeded and is approved by
the Board of Directors of the Fund. There is no commitment, however, by the Fund
to make any such reimbursement. As of December 31, 1997, approximate expensed
paid on behalf of or reimbursed to the Portfolio by Hewitt since September 1,
1989 were: $101,400 for the Full maturity Fixed Income Portfolio; $41,000 for
the Limited Maturity Fixed Income Portfolio; $116,000 for the Diversified Equity
Portfolio; and $10,900 for the Balanced Portfolio.

NOTE 4.
SHORT-TERM DEBT
To facilitate portfolio liquidity, each Portfolio is authorized to borrow
against portfolio securities. During the six months ended December 31, 1997,
there were no borrowings.
