Shareholder Letter
 Dear Shareholder:

 We are pleased to provide you with the Semi-Annual Report on The Commerce
 Funds. In this report, you will find performance and financial information on
 the nine Commerce Funds. The portfolio management team of each Fund also pro-
 vides a review of the factors that have affected performance. To help you put
 that information in context, we offer the following economic and financial
 market update.

                   Economic and Market Update

                   Events in the economy and financial markets are unfolding
                   much as we anticipated. For over a year, it has been our
                   view that the U.S. economy would remain strong, the rest of
                   the world would begin to see renewed growth, and the Fed-
                   eral Reserve would have to act in late 1999 and into 2000
                   to counter potential inflationary price pressures. As noted
                   in our annual letter, this condition began to unfold last
                   fall. As we move through the first half of 2000, the Fed-
                   eral Reserve has increased the Federal Funds rate three
                   more times and financial markets are now in the process of
                   adjusting to this reality. How events develop from here de-
                   pends greatly on upcoming economic reports and market con-
                   ditions. At this moment, it is our assessment that the
                   Federal Reserve is approaching the end of this current cy-
                   cle of rate increases.

                   It is our current expectation that the U.S. economy will
                   begin to experience a moderation in economic activity in
                   the second quarter that will extend into the second half of
                   2000. Monetary policy has been gradually tightened over the
                   past year, and we are just now seeing the first early signs
                   of its effect. Monetary policy works with a lag. The first
                   effects are normally on the financial system, which we are
                   now seeing, and subsequently on the real economy. As eco-
                   nomic activity moderates, budding price pressures should
                   recede. We do not anticipate a major upturn in inflation.

                   One exception could be in the area of energy. Higher gaso-
                   line prices seem assured over the summer months as tight
                   inventories and a lagging increase in crude oil output com-
                   bine to create a supply problem. At the same time, natural
                   gas prices are soaring and the potential of a shortage as
                   we enter the fall and winter months becomes more of a pos-
                   sibility. This is due to the continued strong growth in de-
                   mand and underinvestment in new production over the past
                   several years.

                   The U.S. equity market finished 1999 on a very strong note,
                   despite concerns about the Y2K problem, and after a brief
                   dip in the first several weeks of 2000, roared into March.
                   It was at that point that the tenor of the equity market
                   began to change. The NASDAQ hit its peak on March 10 after
                   a spectacular rally from the lows of last fall of close to
                   85%. The S&P 500 hit its peak several weeks later. The U.S.
                   markets are now in a full blown correction as investors
                   grapple with higher interest rates, lower liquidity, and
                   the potential of an economic slowdown and its impact on
                   earnings growth. The highflying technology sector is in the
                   process of a significant correction, while some of the lag-
                   gard sectors of the past several years have started to per-
                   form better. There has been a clear preference for "value"
                   sectors as opposed to "growth" sectors over the last sev-
                   eral months.

                                                                              1

                   The fixed-income market has also been buffeted by the rise
                   in inflation expectations and Federal Reserve actions.
                   Yields have continued to rise across the maturity spectrum
                   with most of the damage in the short to intermediate matu-
                   rities. One unusual aspect of today's market is the influ-
                   ence of the announced Treasury buy-back program. While not
                   unexpected, the timing and amount caught many investors off
                   guard. This has led to substantial outperformance of U.S.
                   government securities relative to private debt. Addition-
                   ally, the increased risk of economic or financial problems
                   stemming from the Federal Reserve's attempt to slow the
                   U.S. economy has caused investors to demand higher yields
                   from the corporate sector.

                   We continue to expect much volatility over the coming
                   months as the markets deal with the increased uncertainty.
                   On the other hand, we believe the downside in both the eq-
                   uity and fixed-income markets is limited from here, but
                   that on balance, not much net progress will be made. As we
                   noted in this year's edition of Investments: The Long Term
                   Outlook, ". . . the easy money in the U.S. equity market
                   has been made." In this environment, it is important to
                   maintain one's perspective and long-term objectives. The
                   environment and current market conditions also put a high
                   premium on risk management and selectivity.

                   As always, we appreciate your investment, and we look for-
                   ward to being a part of your investment future for years to
                   come.

                   Sincerely,

Short-Term Government Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce Short-Term Gov-
 ernment Fund (the "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   For the six-month period ended April 30, 2000, the Institu-
                   tional Shares of the Fund had a cumulative total return of
                   1.62%, based on Net Asset Value (NAV) (assumes fee waivers
                   and expense reimbursements). The Service Shares had a cumu-
                   lative total return, without sales charge, of 1.44% for the
                   same period based on NAV (assumes fee waivers and expense
                   reimbursements). This compares to the Lipper Short-Term
                   Government Funds Index six-month cumulative return of 1.91%
                   and Salomon Brothers 1-5 Year Treasury/Government Sponsored
                   Index six-month cumulative return of 1.58%. Past perfor-
                   mance is no guarantee of future results. (The Fund's NAV
                   and yield are not guaranteed by the FDIC or the U.S. Gov-
                   ernment or by its agencies, instrumentalities, or sponsored
                   enterprises.)

                   Portfolio Highlights

                   .This continues to be a challenging year for the fixed-in-
                    come market. With continuing strength of the economy and
                    an increase in inflation, interest rates have risen
                    through the first part of 2000. We have also seen short-
                    term interest rates rising faster than long-term rates,
                    resulting in an inverted yield curve.

                   .As short-term interest rates rose above long-term rates,
                    we sold some of our securities with longer maturity dates
                    and reinvested both cash and the proceeds of our sales in
                    the highest-yielding sector of the yield curve.

                   .Looking ahead, we believe the Fund's portfolio is well-po-
                    sitioned relative to its benchmark in terms of yield. We
                    believe the Fund will benefit when mortgage and agency in-
                    terest rate differentials begin to compress relative to
                    U.S. Treasuries.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

Bond Fund Overview
 Dear Shareholder:

 We are pleased to report on the performance of the Commerce Bond Fund (the
 "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 0.74%, based on Net Asset Value (NAV). The Service
                    Shares had a cumulative total return, without sales
                    charge, of 0.62% for the same period based on NAV. This
                    compares to the Lipper Intermediate Investment Grade Debt
                    Funds Index six-month cumulative return of 0.99% and the
                    Lehman Brothers Aggregate Bond Index six-month cumulative
                    return of 1.42%. Past performance is no guarantee of fu-
                    ture results. (The Fund's NAV and yield are not guaranteed
                    by the FDIC or the U.S. Government or by its agencies, in-
                    strumentalities, or sponsored enterprises.)

                   Portfolio Highlights

                   .In general, it has been a difficult period for the bond
                    market. Corporate, mortgage, and asset-backed securities
                    yields have increased dramatically during 2000, largely in
                    response to the robust economy and fears of rising infla-
                    tion. For example, auto sales have been running at a
                    faster pace than 1999 and consumer spending has accelerat-
                    ed.

                   .Against this backdrop, the Federal Reserve has raised
                    overnight interest rates three times over the last six
                    months, pushing Fed Funds from 5.50% to 6.50%. The 30-year
                    mortgage rates have jumped over the same period from 8.00%
                    to 8.40%. This has resulted in a modest return for the
                    Fund of 0.74% over this six-month period as the fixed-in-
                    come markets' decline offset the majority of its coupon
                    income.

                   .The Fund modestly underperformed its Lipper peer group
                    over the most recent six months, largely due to its
                    slightly longer maturity and its investment focus on high-
                    er-yielding, spread-oriented securities. Interest rate
                    differentials between A-rated corporate bonds and similar
                    maturity U.S. Treasuries have widened by more than 40 ba-
                    sis points and are offering extremely attractive value
                    relative to U.S. Government securities. We feel the port-
                    folio is well positioned with both a higher yield and
                    longer interest rate sensitivity relative to its peer
                    group to add value as interest rates peak sometime over
                    the second half of the year.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

COMMERCE BALANCED FUND
Balanced Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce Balanced Fund
 (the "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 8.12%, based on Net Asset Value (NAV) (assumes fee
                    waivers and expense reimbursements). The Service Shares
                    had a cumulative total return, without sales charge, of
                    8.00% for the same period based on NAV (assumes fee waiv-
                    ers and expense reimbursements). This compares to the
                    Lipper Balanced Funds Index six-month cumulative return of
                    5.22%, the composite of 60% of the Standard and Poor's 500
                    Index with Income and 40% of the Lehman Brothers Aggregate
                    Bond Index six-month cumulative return of 5.03%, the S&P
                    500 Index with Income six-month cumulative return of 7.20%
                    and the Lehman Brothers Aggregate Bond Index six-month cu-
                    mulative return of 1.42%. Past performance is no guarantee
                    of future results. (The Fund's NAV is not guaranteed by
                    the FDIC or the U.S. Government or by its agencies, in-
                    strumentalities, or sponsored enterprises.)

                   Portfolio Highlights

                   .In November, we raised the equity weighting of the Fund
                    back up to its long-term target of 60%, as we became in-
                    creasingly optimistic for the outlook of equities. The eq-
                    uity averages surged in November and December. Gains
                    continued until mid-March, when valuation concerns com-
                    bined with rising interest rates cooled investor enthusi-
                    asm.

                   .The equity portion of the Fund uses a blend of large cap
                    growth and value companies. The large cap companies are
                    complemented with mid cap growth issues as well. The com-
                    bination of these different styles leads to a well-diver-
                    sified portfolio. All three styles positively contributed
                    to the equity results over the last six months.

                   .The remaining 40%, invested in bonds has had a difficult
                    six months. Corporate, mortgage, and asset-backed securi-
                    ties yields have increased dramatically, largely in
                    response to a robust economy and fears of rising infla-
                    tion. The Federal Reserve has raised overnight interest
                    rates three times over the six months, pushing Fed Funds
                    from 5.50% to 6.50%. The 30-year mortgage rates have
                    jumped over the same period from 8.00% to 8.40%. The in-
                    creased interest rates have resulted in the bond portion
                    of the portfolio contributing less than 0.50% of the total
                    return of the Fund.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

                   Balanced Fund Team
                   Investment Management Group
                   Commerce Bank, N.A.

COMMERCE GROWTH AND INCOME FUND
Growth and Income Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce Growth and Income
 Fund (the "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 7.22%, based on Net Asset Value (NAV). The Service
                    Shares had a cumulative total return, without sales
                    charge, of 7.08% for the same period based on NAV. This
                    compares to the Lipper Multi-Cap Value Index six-month cu-
                    mulative return of 2.29%, the Russell 1000 Value Index
                    six-month cumulative return of -0.99% and the Standard &
                    Poor's 500 Index with Income six-month cumulative return
                    of 7.20%. Past performance is no guarantee of future re-
                    sults. (The Fund's NAV is not guaranteed by the FDIC or
                    the U.S. Government or by its agencies, instrumentalities,
                    or sponsored enterprises.)

                   Portfolio Highlights

                   .The Federal Reserve's relentless pursuit to control infla-
                    tion is beginning to have an adverse effect on growth
                    stocks supporting high price-to-earnings ratios. The nar-
                    row market we experienced in the last several quarters is
                    reversing and broadening out as investor sentiment is be-
                    ginning to waiver. As the last few months have revealed,
                    money is flowing into the value stocks due to a combina-
                    tion of strong earnings growth coupled with below average
                    prices.

                   .The Fund's results relative to the Russell 1000 Value In-
                    dex improved dramatically over the past six months, having
                    outpaced the index by roughly 8.07%. This out-performance
                    was partially attributable to the enhancements implemented
                    in our stock selection process over the past year. Key
                    changes include the addition of larger capitalization com-
                    panies as well as focusing on companies experiencing an
                    event that draws investor attention to the underlying
                    value of the company.

                   .Within the Fund, the decision to overweight the energy and
                    technology sectors relative to the Russell 1000 Value In-
                    dex was beneficial. Oil and natural gas prices have no-
                    ticeably rebounded from the depressed levels hit within
                    the last two years and should begin to stabilize at levels
                    which will maintain above average profitability for this
                    industry. Our focus has been on the large integrated oil
                    companies along with specialty drillers and oilfield serv-
                    ice providers. In the technology sector, the decision to
                    trim positions as new highs were being reached in March
                    proved to be a winning strategy as this industry has re-
                    versed its fortunes and is under heavy selling pressure.

                   .Looking ahead, we envision solid, yet slowing, U.S. eco-
                    nomic growth as the Federal Reserve's interest rate hikes
                    begin to take effect. Companies relying primarily on com-
                    modity inflation are being trimmed and replaced with those
                    experiencing rising revenues through volume increases. The
                    Fund's underweight position in the financial sector has
                    been beneficial, as this sector has under-performed for
                    the past two years. We are now adding to this sector as we
                    take advantage of the value created by this situation.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

                   Growth and Income Fund Team
                   Investment Management Group
                   Commerce Bank, N.A.

COMMERCE GROWTH FUND
Growth Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce Growth Fund (the
 "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 16.29%, based on Net Asset Value (NAV). The Service
                    Shares had a cumulative total return, without sales
                    charge, of 16.11% for the same period based on NAV. This
                    compares to the Lipper Multi-Cap Core Index six-month cu-
                    mulative return of 14.64% and the Standard & Poor's 500
                    Index with Income six-month cumulative return of 7.20%.
                    Past performance is no guarantee of future results. (The
                    Fund's NAV is not guaranteed by the FDIC or the U.S. Gov-
                    ernment or by its agencies, instrumentalities, or spon-
                    sored enterprises.)

                   Portfolio Highlights

                   .The Fund posted strong returns for the last six months,
                    relative to its benchmark. The majority of the gains oc-
                    curred in November and December. Gains continued until
                    mid-March, when valuation concerns combined with rising
                    interest rates cooled investor enthusiasm.

                   .Technology issues led the surge early in the period. The
                    Fund nearly doubled its weighting in technology from 22%
                    to over 40%. As we increased our technology exposure, we
                    focused on the dominant companies in the semiconductor and
                    telecommunication equipment industries. We also increased
                    many of our positions in seasoned companies who offer
                    leading products in building the infrastructure of the
                    Internet. We did not participate in the hot new issue mar-
                    ket of Internet-related companies early in the period,
                    which hindered our results; however, many of these company
                    stock prices have since plunged from their highs of last
                    December.

                   .The assets utilized to increase the weighting in technol-
                    ogy came from three sectors. We reduced our exposure to
                    consumer cyclical stocks (retailers, autos, housing, etc.)
                    because of our concern with the Federal Reserve's resolve
                    to increase interest rates high enough to slow down the
                    economy. In the face of rising interest rates and a poten-
                    tial profit margin squeeze later this year, we continued
                    to reduce our exposure to financial stocks. We also re-
                    duced our exposure to health care issues. The political
                    risks seem to be intensifying for some form of drug price
                    controls as we move closer to the elections.

                   .Looking ahead, we believe the Fund is well-positioned to
                    provide the potential for strong, long-term results. The
                    Fund's portfolio is currently well-diversified in a group
                    of companies whose earnings are growing far in excess of
                    the Standard & Poor's 500 Index average.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

                   Growth Fund Team
                   Investment Management Group

COMMERCE MIDCAP FUND
MidCap Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce MidCap Fund (the
 "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 24.22%, based on Net Asset Value (NAV). The Service
                    Shares had a cumulative total return, without sales
                    charge, of 24.10% for the same period based on NAV. This
                    compares to the Lipper Mid-Cap Core Index six-month cumu-
                    lative return, of 29.70% and the Standard & Poor's Mid-Cap
                    400 Index six-month cumulative return of 21.26%. Past per-
                    formance is no guarantee of future results. (The Fund's
                    NAV is not guaranteed by the FDIC or the U.S. Government
                    or by its agencies, instrumentalities, or sponsored enter-
                    prises.)

                   Portfolio Highlights

                   .The last six months have produced some of the most vola-
                    tile swings in the stock markets ever recorded. Driven by
                    the "new economy" frenzy in Internet and telecommunica-
                    tions stocks, the technology sectors of the market re-
                    corded unprecedented gains through mid-March. Not
                    surprisingly, the technology-heavy indices, particularly
                    the small-cap and mid-cap benchmarks, recorded impressive
                    gains. It was an unusual period in which greater levels of
                    risk in a portfolio were well rewarded.

                   .Most recently, the market has taken on a decidedly differ-
                    ent tone. Rising interest rates have burst the speculative
                    bubble that was driving tech stock valuations to unrealis-
                    tic levels. Suddenly, sectors that languished for quite
                    some time appear to be a safe harbor, in the short term,
                    in which to ride out the storm of uncertainty. Utility,
                    financial, energy, and health care stocks have been surg-
                    ing as investors scramble to diversify their holdings more
                    broadly.

                   .Near term, as the markets adjust to what necessarily must
                    become a slower rate of economic growth next year, we ex-
                    pect this level of volatility to persist. Meanwhile, we
                    have thoroughly reviewed the holdings in our portfolio,
                    and are comfortable with the long-term prospects of our
                    investments. We are already formulating investment strate-
                    gies to take advantage of the opportunities which will
                    present themselves in an era of global economic growth.

                   We thank you for your investment and look forward to your
                   continued confidence.

International Equity Fund Overview
 Dear Shareholder:

 We are pleased to report on the performance of the Commerce International Eq-
 uity Fund (the "Fund") for the six-month period ended April 30, 2000.

                   Performance Review

                   .For the six-month period ended April 30, 2000, the Insti-
                    tutional Shares of the Fund had a cumulative total return
                    of 13.18%, based on Net Asset Value (NAV) (assumes expense
                    waivers). The Service Shares had a cumulative total re-
                    turn, without sales charge, of 13.02% for the same period
                    based on NAV (assumes expense waivers). This compares to
                    the Lipper International Equity Funds Index six-month cu-
                    mulative return of 13.59% and the Morgan Stanley Capital
                    International Europe, Australia, and Far East Index
                    ("EAFE") six-month cumulative return of 6.83%. Past per-

                   Portfolio Highlights

                   .The global equity markets have experienced a great deal of
                    volatility during the past year. After several quarters of
                    leadership, the dynamic "new economy" stocks in the
                    telecom, media, and technology ("TMT") sectors declined
                    during the past several months, while the "old economy"
                    stocks (in sectors like financial, pharmaceuticals, and
                    energy) rose.

                   .The Fund's relative performance during the past year bene-
                    fited from an underweighting in Japan relative to its
                    benchmark and Lipper peer group, as Japan's equity market
                    weakened. In addition, strong performance from the Latin
                    American markets, where the Fund has an overweighting,
                    helped relative performance. Our "Growth at a Reasonable
                    Price" style has returned to favor in the first part of
                    this calendar year, so that stock selection has also been
                    aiding relative performance.

                   .Over 60% of the portfolio continues to be invested in the
                    European equity markets. Business and consumer confidence
                    in these markets continues to be high, and unemployment is
                    declining. A stronger focus on maximizing shareholder
                    value is evident in the numerous mergers and acquisitions
                    which continue apace. Japan, while showing some signs of
                    economic recovery, must overcome corporate restructuring
                    which is producing high unemployment and, therefore, a
                    weak consumer sector. A number of the Pacific Rim econo-
                    mies are enjoying strong economic rebounds. We expect that
                    the international equity markets will remain somewhat vol-
                    atile in the coming months, as investors gauge the possi-
                    bility of sharper U.S. interest rate increases, and
                    continue to reassess the "new economy" sectors.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

                               COMMERCE NATIONAL TAX-FREE INTERMEDIATE BOND FUND
National Tax-Free Intermediate Bond Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce National Tax-Free
 Intermediate Bond Fund (the "Fund") for the six-month period ended April 30,
 2000.

                   Performance Review

                   For the six months ended April 30, 2000, the Institutional
                   Shares of the Fund had a cumulative total return of 1.96%,
                   based on Net Asset Value (NAV) (assumes fee waivers and ex-
                   pense reimbursements). This compares to the Lipper Interme-
                   diate Municipal Funds Index six-month cumulative return of
                   1.74% and the Merrill Lynch Municipal Intermediate Index
                   six-month cumulative return of 1.97%. Past performance is
                   no guarantee of future results. (The Fund's NAV and yield
                   are not guaranteed by the FDIC or the U.S. Government or by
                   its agencies, instrumentalities, or sponsored enterprises.)

                   Portfolio Highlights

                   .The strong domestic economy, rising commodity prices and
                    wage pressures have led the Federal Reserve to increase
                    short-term interest rates by 1.25% from May 1999 to April
                    2000. In response, the municipal bond yield curve has
                    flattened. Over the last six months, short-term municipal
                    bond yields rose 0.80% while long-term municipal bond
                    yields have actually declined by 0.09%.

                   .In addition to the rising interest rates, the municipal
                    market has been hampered by a fall in demand on the insti-
                    tutional level, which began in the fourth quarter of 1998.
                    Municipal bond mutual funds have experienced net redemp-
                    tions, as the continued rise in interest rates has dimin-
                    ished their appeal. In addition, an industry-wide
                    profitability squeeze has motivated property and casualty
                    insurers to reduce their purchases of municipals in favor
                    of taxable fixed-income securities. Retail or individual
                    investors have provided the only consistent source of li-
                    quidity.

                   .Our main focus for the Fund continues to be improving its
                    relative yield. To accomplish this, we have concentrated
                    on adding higher yielding sectors such as housing, higher
                    education, and transportation. One exception has been the
                    health care sector, where we continue to cut back the
                    Fund's exposure. We've seen that even the most profitable
                    hospitals are having a difficult time adjusting to the re-
                    duction in Medicare reimbursement laid out in the 1997
                    Balanced Budget Act.

                   .The last six months have been a continuation of the long-
                    standing trend of under-performance by municipal bonds
                    versus U.S. Treasury securities. Since 1996, municipal
                    yields have risen an average of 60 basis points, whereas
                    U.S. Treasury bond yields are flat to slightly higher.
                    When yields rise, the values of existing bonds fall. Be-
                    cause of this trend, we believe municipal bonds now offer
                    investors very attractive yields relative to U.S. Treasury
                    bonds.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,

COMMERCE MISSOURI TAX-FREE INTERMEDIATE BOND FUND
Missouri Tax-Free Intermediate Bond Fund Overview
 Dear Shareholder,

 We are pleased to report on the performance of the Commerce Missouri Tax-Free
 Intermediate Bond Fund (the "Fund") for the six-month period ended April 30,
 2000.

                   Performance Review

                   For the six months ended April 30, 2000, the Institutional
                   Shares of the Fund had a cumulative total return of 1.89%,
                   based on Net Asset Value (NAV) (assumes fee waivers and ex-
                   pense reimbursements). This compares to the Lipper Interme-
                   diate Municipal Funds Index six-month cumulative return of
                   1.74% and the Merrill Lynch Municipal Intermediate Index
                   six-month cumulative return of 1.97%. Past performance is
                   no guarantee of future results. (The Fund's NAV and yield
                   are not guaranteed by the FDIC or the U.S. Government or by
                   its agencies, instrumentalities, or sponsored enterprises.)

                   Portfolio Highlights

                   .The strong domestic economy, rising commodity prices and
                    wage pressures have led the Federal Reserve to increase
                    short-term interest rates by 1.25% from May 1999 to April
                    2000. In response, the municipal bond yield curve has
                    flattened. Over the last six months, short-term municipal
                    bond yields rose 0.80% while long-term municipal bond
                    yields have actually declined by 0.09%.

                   .In addition to the rising interest rates, the municipal
                    market has been hampered by a fall in demand on the insti-
                    tutional level, which began in the fourth quarter of 1998.
                    Municipal bond mutual funds have experienced net redemp-
                    tions, as the continued rise in interest rates has dimin-
                    ished their appeal. In addition, an industry-wide
                    profitability squeeze has motivated property and casualty
                    insurers to reduce their purchases of municipals in favor
                    of taxable fixed-income securities. Retail or individual
                    investors have provided the only consistent source of li-
                    quidity.

                   .Our main focus for the Fund continues to be improving its
                    relative yield. To accomplish this, we have concentrated
                    on adding higher yielding sectors such as housing, higher
                    education, and transportation. One exception has been the
                    health care sector, where we continue to cut back the
                    Fund's exposure. We've seen that even the most profitable
                    hospitals are having a difficult time adjusting to the re-
                    duction in Medicare reimbursement laid out in the 1997
                    Balanced Budget Act.

                   .The last six months have been a continuation of the long-
                    standing trend of underperformance by municipal bonds ver-
                    sus U.S. Treasury securities. Since 1996, municipal yields
                    have risen an average of 60 basis points, whereas U.S.
                    Treasury bond yields are flat to slightly higher. When
                    yields rise, the values of existing bonds fall. Because of
                    this trend, we believe municipal bonds now offer investors
                    very attractive yields relative to U.S. Treasury bonds.

                   We thank you for your investment and look forward to your
                   continued confidence.

                   Sincerely,
                   Fixed-Income Funds Team
                   Investment Management Group

COMMERCE FUNDS
Notes to Financial Statements
April 30, 2000 (Unaudited)
 1. ORGANIZATION

 The Commerce Funds (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940, as amended (the "1940 Act"), as an
 open-end, management investment company. The Trust consists of nine portfo-
 lios (individually, a "Fund" and collectively, the "Funds"): Short-Term Gov-
 ernment Fund, Bond Fund, Balanced Fund, Growth and Income Fund, Growth Fund,
 MidCap Fund, International Equity Fund, National Tax-Free Intermediate Bond
 Fund and Missouri Tax-Free Intermediate Bond Fund (formerly National Tax-Free
 Bond Fund and Missouri Tax-Free Bond Fund, respectively). Each of the Funds
 offers two classes of shares, Institutional Shares and Service Shares (except
 National Tax-Free Intermediate Bond Fund and Missouri Tax-Free Intermediate
 Bond Fund which only offer Institutional Shares). Each Fund is registered as
 a diversified management investment company, other than the Missouri Tax-Free
 Intermediate Bond Fund, which is registered as non-diversified under the 1940
 Act.

 2. SIGNIFICANT ACCOUNTING POLICIES

 The following is a summary of significant accounting policies consistently
 followed by the Funds. The preparation of financial statements in conformity
 with generally accepted accounting principles requires management to make es-
 timates and assumptions that may affect the reported amounts.

 A. Investment Valuation -- Investments in securities traded on a U.S. or for-
 eign securities exchange or the NASDAQ system are valued daily at their last
 sale price on the principal exchange on which they are traded. If no sale oc-
 curs, securities are valued at the last bid price. Debt securities are valued
 at prices supplied by an independent pricing service, broker / dealer-sup-
 plied valuations or matrix pricing systems. Unlisted equity and debt securi-
 ties for which market quotations are available are valued at the last sale
 price on valuation date, or if no sale occurs, at the last bid price. Short-
 term debt obligations maturing in sixty days or less are valued at amortized
 cost. Securities for which quotations are not readily available are valued at
 fair value using methods approved by the Trust's Board of Trustees.
   Investing in emerging markets may involve special risks and considerations
 not typically associated with investing in the United States. These risks in-
 clude revaluation of currencies, high rates of inflation, repatriation re-
 strictions on income and capital, and adverse political and economic
 developments. Moreover, securities issued in these markets may be less liq-
 uid, may be subject to government ownership controls and delayed settlements,
 and their prices may be more volatile than those of comparable securities in
 the United States.

 B. Security Transactions and Dividend Income -- Security transactions are re-
 corded as of the trade date. Realized gains and losses on sales of portfolio
 securities are calculated using the identified-cost basis. Dividend income is
 recorded on the ex-dividend date. Dividends for which a Fund has the choice
 to receive either cash or stock are recognized as investment income in an
 amount equal to the cash dividend.

 C. Premiums and Discounts on Debt Securities Owned -- The National Tax-Free
 Intermediate Bond and the Missouri Tax-Free Intermediate Bond Funds amortize
 premiums on debt securities on the effective yield basis, and do not accrete
 market discounts on debt securities. The Growth, MidCap and International Eq-
 uity Funds accrete market discounts and amortize premiums on a yield to matu-
 rity basis. The Short-Term Government, Bond, Balanced and Growth and Income
 Funds do not accrete market discounts or amortize premiums on long-term debt
 securities.

                                                                 COMMERCE FUNDS
   The Short-Term Government, Bond and Balanced Funds invest in mortgage-
 backed securities. Certain mortgage security paydown gains and losses are
 taxable as ordinary income. Such paydown gains and losses increase or de-
 crease taxable ordinary income available for distribution and are classified
 as interest income in the accompanying Statements of Operations. For all
 Funds, original issue discounts ("OID") on debt securities are amortized to
 interest income over the life of the security with a corresponding increase
 in the cost basis of that security. OID amortization on mortgage backed REMIC
 securities is initially recorded based on estimates of principal paydowns us-
 ing the most recent OID factors available from the issuer. Recorded amortiza-
 tion amounts are adjusted when actual OID factors are received.

 D. Foreign Currency Translations --  The books and records of the Funds are
 maintained in U.S. dollars. Amounts denominated in foreign currencies are
 translated into U.S. dollars on the following basis: (i) investment valua-
 tions, foreign currency and other assets and liabilities initially expressed
 in foreign currencies are converted each business day into U.S. dollars based
 on current exchange rates; and (ii) purchases and sales of foreign invest-
 ments, income and expenses are converted into U.S. dollars based upon cur-
 rency exchange rates prevailing on the respective dates of such transactions.
   Net realized gain (loss) on foreign currency transactions represent: (i)
 foreign exchange gains and losses from the sale of foreign currencies; (ii)
 foreign exchange gains and losses between trade date and settlement date on
 investment securities transactions and foreign exchange contracts; and (iii)
 foreign exchange gains and losses from the difference between amounts of div-
 idends and interest recorded and the amounts actually received. Net
 unrealized gain (loss) on translation of assets and liabilities denominated
 in foreign currencies arises from changes in the value of assets and liabili-
 ties.

 E. Forward Foreign Currency Exchange Contracts -- The International Equity
 Fund may enter into forward foreign currency exchange contracts for the pur-
 chase of a specific foreign currency at a fixed price on a future date as a
 hedge or cross-hedge against either specific transactions or portfolio posi-
 tions. The Fund may also purchase and sell forward contracts to seek to in-
 crease total return. All commitments are "marked-to-market" daily at the
 applicable translation rates. The Fund realizes gains or losses at the time a
 forward contract is offset by entry into a closing transaction or extin-
 guished by delivery of the currency. Risks may arise upon entering into these
 contracts from the potential inability of counterparties to meet the terms of
 their contracts and from unanticipated movements in the value of a foreign
 currency relative to the U.S. dollar.

 F. Segregation Transactions -- The Funds may enter into certain derivative
 transactions to seek to increase total return. Forward foreign currency ex-
 change contracts, futures contracts, written options, when-issued securities
 and forward commitments represent examples of such transactions. As a result
 of entering into these transactions, the Funds are required to segregate liq-
 uid assets on the accounting records equal to or greater than the market
 value of the corresponding transactions.

 G. Repurchase Agreements -- During the term of a repurchase agreement, the
 value of the underlying securities, including accrued interest, is required
 to equal or exceed the value of the repurchase agreement. The underlying se-
 curities for all repurchase agreements are held in safekeeping in the custom-
 er-only account, at the Funds' custodian, or at sub-custodians.


                                                                             49

 H. Dividend Distributions to Shareholders -- Dividends from net investment
 income are declared daily and paid monthly by the Short-Term Government,
 Bond, National Tax-Free Intermediate Bond and Missouri Tax-Free Intermediate
 Bond Funds; declared and paid quarterly by the Balanced and Growth and Income
 Funds; and declared and paid annually by the MidCap, Growth and International
 Equity Funds. Each Fund's net realized capital gains (including net short-
 term capital gains), if any, are declared and distributed at least annually.
 Distributions to shareholders are recorded on the ex-dividend date.
 I. Deferred Organization Expenses -- Organization costs are being amortized
 on a straight-line basis over a period of five years beginning with the com-
 mencement of each Fund's operations.

 J. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual Fund of the Trust are allocated to the Funds based on each
 Fund's relative average daily net assets for the period. Service Class share-
 holders bear all expenses and fees relating to the Distribution Plan.

 K. Federal Taxes --  It is each Fund's policy to comply with the requirements
 of the Internal Revenue Code applicable to regulated investment companies and
 to distribute each year substantially all of its investment company tax-ex-
 empt and taxable income and capital gains to its shareholders. Accordingly,
 no federal tax provisions are required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of a portfolio's distributions may be shown in the accompanying
 financial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in capital, de-
 pending on the type of book/tax differences that may exist as well as timing
 differences associated with having different book and tax year ends.
   As of the Trust's most recent tax year-end, the Short-Term Government and
 Growth and Income Funds had capital loss carryforwards for U.S. federal in-
 come tax purposes. These amounts are available to be carried forward to off-
 set future capital gains of the Funds to the extent permitted by applicable
 laws or regulations.

   In addition, when the International Equity Fund's average net assets reach
 $200 million, the Sub-Advisor has agreed to waive fees in excess of 0.50% of
 the average daily net assets of the Fund.
   In addition, for the six months ended April 30, 2000, the Advisor has vol-
 untarily agreed to reimburse expenses (excluding interest, taxes, service
 share distribution expenses and extraordinary expenses) to the extent that
 such expenses exceed, on an annualized basis, .68%, .88%, 1.20%, 1.13%,
 1.72%, .70% and .65% of average net assets of the Short-Term Government,
 Bond, Growth and Income, Growth, International Equity, National Tax-Free In-
 termediate Bond Fund and Missouri Tax-Free Intermediate Bond Funds, respec-
 tively. Effective March 1, 2000, the Advisor has voluntarily agreed to
 reimburse expenses (excluding interest, taxes, service share distribution ex-
 penses and extraordinary expenses) for the Balanced Fund to the extent that
 such expenses exceed, on an annualized basis 1.03% of average net assets.
 Prior thereto, the expense limitation was 1.13% of average net assets. The
 effect of these reimbursements by the Advisor for the six months ended April
 30, 2000, was to reduce expenses by $7,451, $57,720, $18,032 and $18,228 for
 the Short-Term Government, Balanced, National Tax-Free Intermediate Bond and
 Missouri Tax-Free Intermediate Bond Funds, respectively. The amount reimburs-
 able to the Short-Term Government, Balanced, National Tax-Free Intermediate
 Bond and Missouri Tax-Free Intermediate Bond Funds at April 30, 2000, was
 $4,983, $8,260, $6,392 and $8,506 respectively, and are netted in "Advisory
 fees payable" in the accompanying Statements of Assets and Liabilities.
   As of September 1, 1999, Goldman, Sachs & Co. established a new operating
 division named the Investment Management Division. This newly created entity
 includes Goldman Sachs Asset Management ("GSAM"). GSAM serves as the Trust's
 administrator, pursuant to an Administration Agreement. Under the Administra-
 tion Agreement, GSAM administers the Trust's business affairs. As compensa-
 tion for the services rendered under the Administration Agreement and its
 assumption of related expenses, GSAM is entitled to a fee, computed daily and
 payable monthly, at an annual rate of .15% of the average daily net assets of
 each Fund.
   Goldman Sachs & Co. serves as Distributor of shares of the Funds pursuant
 to a Distribution Agreement and may receive a portion of the sales charge im-
 posed on the sale of shares of the Funds. The maximum sales charge imposed on
 the sale of Service Shares of the Short-Term Government Fund is 2.00%; for
 all other Funds' Service Shares, the maximum sales charge is 3.50%. Goldman
 Sachs & Co. has advised the Trust that it has retained approximately $5,000
 on the sale of shares of the Funds for the six months ended April 30, 2000.
   The Trust, on behalf of each Fund (except the National Tax-Free Intermedi-
 ate Bond Fund and Missouri Tax-Free Intermediate Bond Fund), has adopted a
 Distribution Plan for Service Shares pursuant to Rule 12b-1 under the 1940
 Act. Under the distribution plan, payments by each Fund for distribution ex-
 penses may not exceed .25% (annualized) of the average daily net assets of
 the Fund's Service Shares.
   Pursuant to a Shareholder Administrative Services Plan adopted by its Board
 of Trustees, the Funds may enter into agreements with service organizations,
 such as banks and financial institutions, which may include the Advisor and
 its affiliates ("Service Organizations"), under which they will render share-
 holder administration support services. For these services, the Service Orga-
 nizations are entitled to receive fees from a Fund at an annual rate of up to
 .25% of the average daily net asset value of Fund shares beneficially owned
 by clients of such Service Organizations.

 5. CONCENTRATION OF RISK

   Under normal conditions, the Missouri Tax-Free Intermediate Bond and Na-
 tional Tax-Free Intermediate Bond Funds will invest at least 80% of their net
 assets in tax-exempt securities. Although they do not expect to do so, the
 Funds may invest up to 20% of their net assets in private activity bonds that
 may subject certain investors to the federal alternative minimum tax.
   In addition, the Missouri Tax-Free Intermediate Bond Fund invests
 substantially all of its assets in debt obligations of issuers located in the
 State of Missouri. The National Tax-Free Intermediate Bond Fund invests
 substantially all of its assets in debt securities issued by or on behalf of
 states, territories and possessions of the U.S. The issuers' abilities to
 meet their obligations may be affected by the states' economic and political
 developments.
   The International Equity Fund invests a portion of its assets in emerging
 markets. Emerging markets securities are volatile. They are subject to sub-
 stantial currency fluctuations and sudden economic and political develop-
 ments. At times, the securities held by the International Equity Fund may be
 subject to abrupt and severe price declines.

                                                                             53
