ABBREVIATIONS AND OTHER INFORMATION

With respect to the Schedules of Investments, the percentage shown for each
investment category reflects the value of investments in that category as a
percentage of total net assets.


Interest rates represent either the stated coupon rate, annualized yield on date
of purchase for discounted notes, or, for floating rate securities, the current
reset rate.


Maturity dates represent the stated date on the security, the next interest
reset date or next putable dates for floating rate securities or the prerefunded
date for these types of securities.


Prerefunding is a procedure in which a bond issuer floats a second bond in order
to pay off the first bond at the first call date. The proceeds from the sale of
the second bond are safely invested, usually in Treasury securities, that will
mature at the first call date of the first bond issue. Those first bonds are
said to be prerefunded after this operation has taken place.

                                                NORTHERN FUNDS Semiannual Report

NOTES TO THE FINANCIAL STATEMENTS
SEPTEMBER 30, 2000 (UNAUDITED)

1. ORGANIZATION

Northern Funds, (the "Trust") is a Delaware business trust, which was formed on
February 7, 2000, and is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company. The Money Market, U.S.
Government Money Market, U.S. Government Select Money Market, Municipal Money
Market and California Municipal Money Market Funds (collectively the "Funds")
are separate, diversified investment portfolios of Northern Funds, except the
California Municipal Money Market Fund which is a non-diversified portfolio of
Northern Funds. Non-diversified portfolios may invest a relatively high
percentage of their net assets in obligations of a limited number of issuers.
Each of the Funds maintains its own investment objective. The Funds were
formerly series of Northern Funds, a Massachusetts business trust, and were
reorganized into the Trust on July 31, 2000.

     The Funds have entered into an Investment Advisory Agreement with The
Northern Trust Company ("Northern Trust" or the "Adviser"). Northern Trust also
serves as co-administrator, custodian, fund accountant and transfer agent for
the Funds.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Funds. These policies are in conformity with generally accepted
accounting principles ("GAAP"). The preparation of financial statements in
conformity with 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 revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A    VALUATION OF SECURITIES - Short-term investments held by the Funds are
     valued using the amortized cost method, which approximates market value.
     Under this method, investments purchased at a discount or premium are
     valued by amortizing the difference between the original purchase price and
     maturity value of the issue over the period to maturity. Insurance funding
     agreements are valued at cost plus accrued interest, which approximates
     market value. Any securities for which no current quotations are readily
     available are valued at fair value as determined in good faith by the
     Adviser under the supervision of the Board of Trustees.

B    REPURCHASE AGREEMENTS - During the term of a repurchase agreement, the
     market value of the underlying collateral, including accrued interest, is
     required to equal or exceed the market value of the repurchase agreement.
     The underlying collateral for all repurchase agreements is held in a
     customer-only account of Northern Trust, as custodian for the Funds, at the
     Federal Reserve Bank of Chicago.

C    INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded
     as of the trade date. The Funds determine the gain or loss realized from
     investment transactions by using an identified cost basis method. Interest
     income is recognized on an accrual basis and includes amortization of
     discounts and premiums.

D    EXPENSES - The Funds are charged for those expenses that are directly
     attributable to each Fund. Expenses that are not directly attributable to a
     Fund are typically allocated among the Funds in proportion to their
     respective net assets.

E    DISTRIBUTIONS TO SHAREHOLDERS - Dividends from net investment income are
     declared daily and paid monthly.

          Distributions of net realized capital gains, if any, are declared at
     least annually. Distributions to shareholders are recorded on the
     ex-dividend date.

          The timing and character of distributions determined in accordance
     with federal income tax regulations may differ from financial statement
     amounts determined in accordance with generally accepted accounting
     principles due to differences in the treatment and recognition of
     investment income and realized gains (losses). These differences are
     primarily related to capital loss carryforwards. Certain differences in
     treatment of income and capital gains for distributions, which are
     permanent, may result in periodic reclassifications in the Funds' capital
     accounts.

          During the six months ended September 30, 2000, all of the dividends
     derived from net investment income paid by each of the Municipal Money
     Market and California Municipal Money Market Funds were "exempt-interest
     dividends," excludable from gross income for Federal income tax purposes.
     Further, all such dividends paid by the California Municipal Money Market
     Fund were "California exempt-interest dividends," exempt from California
     state personal income tax.


                                       43
<PAGE>


F    FEDERAL INCOME TAXES - No provision for federal income taxes has been made
     since the Funds intend to comply with the requirements of the Internal
     Revenue Code available to regulated investment companies and to distribute
     substantially all of their taxable income to their shareholders.


3. INVESTMENT ADVISORY AND OTHER AGREEMENTS

Pursuant to its advisory agreement with the Funds, the Adviser is entitled to

     The waivers and reimbursements of Northern Trust described above are
voluntary and may be terminated by Northern Trust at any time at its discretion.

     The Funds have a co-administration agreement with Northern Trust and
PFPC,Inc. ("the co-administrators"), for certain administrative services.
Pursuant to their co-administration agreement with the Funds, the
co-administrators are entitled to receive a fee, computed daily and payable
monthly, at the annual rate of 0.15% of each Fund's daily net assets.

4. BANK LOANS

The Funds maintain a $50,000,000 revolving bank credit line for liquidity and
other purposes. Borrowings under this arrangement bear interest at 0.45% above
the Fed Funds rate.

      As of September 30, 2000, there were no outstanding borrowings.
