Letter to Shareholders

The twelve-month period ended September 30, 2004 saw the seven-day yield of Government Money Market rise from 0.41% to 0.96%, as short-term rates moved upward from historic lows. Over the course of this one-year period, the Federal Reserve Board raised rates three times (0.25% on each occasion), beginning on June 30, 2004. Money market rates and the Federal Funds rate are closely linked, with Fed rate moves rapidly reflected in the yield of money market funds. In addition to these raises, the Federal Reserve has announced their intent to "normalize" rates over time, a position which suggests additional increases above their current 1.75% level.

Market Overview

As we entered this annual period, in the fall of 2003, there were signs that the economy and equity market had finally made a turn. The economic expansion was putting upward pressure on interest rates; pressure which was counterbalanced by the Federal Reserve's conviction that they could hold interest rates at low levels for a considerable time. One key factor was the stubbornly low employment statistics, which continued to disappoint, and in doing so created doubt about the depth of the economic rebound. On the other hand, there was growing evidence that economic activity had entered a strong and sustainable recovery. Monetary and fiscal stimulus seemed to be gaining traction, and growth was broad-based, with advancing capital spending, improving inventory stockpiles, strong housing, and stable consumer expenditures.

As the year progressed, we saw continued tension between economic expansion and the Fed's low rates. On June 30, 2004 the Fed did indeed raise the Fed Fund rate 25 basis points and put the markets on notice that the June increase would be just the first of a series of increases. Improving jobs data and fears of inflation suggested an economy that was just too strong to warrant a Fed Funds rate of 1.00% or even 1.75%, the rate that the Fed maintained at the end of this annual period. Although market fundamentals pointed towards higher interest rates, we saw a number of mitigating factors emerge over the course of the summer. Bad news from Iraq, higher oil prices, and fear of terrorism kept money flowing into bonds and produced doubts about the sustainability of the expansion. In addition, record buying of U.S. bonds by foreign buyers also dampened prices.

Outlook

While we view the recent moderation in economic growth as a natural step in an ongoing recovery, we are focusing on key economic fundamentals as we look forward to the coming 12-18 months. The current economic expansion is maintaining its momentum despite rising short-term rates. In fact the Fed Funds rate remains well below 3.5%, many economists' estimate of "neutral" monetary policy. After flaring up in the second quarter to over 4%, the Consumer Price Index has settled to an annual rate of 2%. Until economic growth resumes and employment growth steps higher, inflation should remain stable.

We believe that the Federal Open Market Committee will continue to "normalize" short-term interest rates at a gradual pace. The Fed Funds rate of 1.75% is still below prevailing inflation and extremely stimulative for the economy. Our base case expects the Fed to persist in its path to neutral monetary policy, with an endpoint in the 3% to 4% range over the next 18 months. More aggressive rate increases could unfold if the labor markets heat up, or if inflation pressures flare in the first half of 2005.

With rates finally on the rise, money market investors have seen some relief from the lowest returns in memory. With prospects for increasing rates, the attraction of holding short-term government and government agency notes is highlighted, especially in light of the considerable domestic and world-wide uncertainties. We continue to manage Government Money Market to produce the best possible returns while maintaining the low-risk that we believe is a chief attraction to our investors. Thank you for your continued confidence in the fund.

Sincerely,

Report of Independent Registered Public Accounting Firm

TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF MOSAIC GOVERNMENT MONEY MARKET

We have audited the accompanying statement of net assets of Mosaic Government Money Market (the "Fund") as of September 30, 2004, the related statement of operations for the year then ended, and statement of changes in net assets for the year then ended. Our audit also included the financial highlights for the year ended September 30, 2004. 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 audit. The statement of changes in net assets for the year ended September 30, 2003 and financial highlights for each of the four years in the period then ended were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements in their report dated November 11, 2003.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2004, by correspondence with the Fund's custodian. 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 audit provides a reasonable basis for our opinion.

In our opinion, the 2004 financial statements and 2004 financial highlights referred to above present fairly, in all material respects, the financial position of the Fund as of September 30, 2004, the results of its operations, the changes in its net assets, and the changes in financial highlights for the year ended September 30, 2004, in conformity with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

For the year ended September 30, 2004

1. Summary of Significant Accounting Policies. Mosaic Government Money Market (the "Fund") is registered with the Securities and Exchange Commission under the Investment Company Act of 1940 as an open-end, diversified investment management company. The Fund invests solely in securities issued by the U.S. Government or any of its agencies or instrumentalities or in repurchase agreements backed by such securities. Because the Fund is 100% no-load, its shares are offered and redeemed at the net asset value per share.

Securities Valuation: The Fund uses the amortized cost method of valuation whereby portfolio securities are valued at acquisition cost as adjusted for amortization of premium or accretion of discount.

Investment Transactions: Investment transactions are recorded on a trade date basis. The cost of investments sold is determined on the identified cost basis for financial statement and federal income tax purposes.

Investment Income: Interest income is recorded on an accrual basis. Bond premium is amortized and original issue discount and market discount are accreted over the expected life of each applicable security using the effective interest method.

Distribution of Income: Net investment income, determined as gross investment income less total expenses, is declared as a dividend each business day. Dividends are distributed to shareholders or reinvested in additional shares as of the close of business at the end of each month. Distributions paid during the years ended September 30, 2004 and 2003 were identical for book purposes and tax purposes.

Income Tax: No provision is made for Federal income taxes since it is the intention of the Fund to comply with the provisions of the Internal Revenue Code available to investment companies and to make the requisite distribution to shareholders of taxable income which will be sufficient to relieve it from all or substantially all Federal income taxes.

Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. Such estimates affect the reported amounts of assets and liabilities and reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

2. Investment in Repurchase Agreements. When the Fund purchases securities under agreements to resell, the securities are held in safekeeping by the Fund's custodian bank as collateral. Should the market value of the securities purchased under such an agreement decrease below the principal amount to be received at the termination of the agreement plus accrued interest, the counterparty is required to place an equivalent amount of additional securities in safe-keeping with the Fund's custodian bank. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other registered investment companies having Advisory and Services Agreements with the same advisor, transfers uninvested cash balances into a joint trading account. The aggregate balance in this joint trading account is invested in one or more consolidated repurchase agreements whose underlying securities are U.S. Treasury or federal agency obligations. The Fund has approximately a 1.8% interest in the consolidated repurchase agreement of $27,689,000 collateralized by $28,239,343 in United States Treasury Notes. Proceeds at maturity are $27,690,161.

3. Investment Advisory Fee and Other Transactions with Affiliates. The Investment Advisor to the Fund, Madison Mosaic, LLC, a wholly owned subsidiary of Madison Investment Advisors, Inc. (the "Advisor"), earns an advisory fee equal to 0.5% per annum of the average net assets of the Fund. The fee is accrued daily and paid monthly. Effective December 9, 2002, the Advisor irrevocably waived 0.25% of this fee for the Fund totaling $94,074 for the year ended September 30, 2004. This waiver may end at any time.

The Advisor will reimburse the Fund for the amount of any expenses of the Fund (less certain expenses) that exceed 1.5% per annum of the average net assets of the Fund up to $40 million and 1% per annum of such amount in excess of $40 million. No amounts were reimbursed to the Fund by the Advisor for the year ended September 30, 2004.

4. Other Expenses. Under a separate Services Agreement, the Advisor will provide or arrange for the Fund to have all other necessary operational and support services for a fee based on a percentage (0.38%) of average net assets. The fee is accrued daily and paid monthly.

Effective May 13, 2004, the Fund began paying the expenses of the Fund's Independent Trustees and auditor ("Independent Service Providers") directly. Therefore, the Fund reduced the amount of fees paid to the Advisor prior to May 13, 2004 described above by the amounts paid directly to the Independent Service Providers. Through September 30, 2004, the Fund had a reduced services fee of 0.35%. The Fund has paid $3,852 directly for Independent Service Provider fees.

5. Fund Expenses.

Example: This Example is intended to help you understand your costs (in dollars) of investing in the Fund and to compare these costs with the costs of investing in other mutual funds. See footnotes 3 and 4 above for an explanation of the types of costs charged by the funds.

This Example is based on an investment of $1,000 invested on April 1, 2004 and held for the six months ended September 30, 2004.

Actual Expenses

The table below titled "Based on Actual Total Return" provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,500 ending account valued divided by $1,000 = 8.5), then multiply the result by the number under the heading entitled "Expenses Paid During the Period."

Based on Actual Total Return¹

	Actual Total Return2	Beginning Account Value	Ending Account Value	Annualized Expense Ratio3	Expenses Paid During the Period3
Government Money Market	0.31%	$1,000.00	$1,003.06	0.63%	$3.15
1For the six months ended September 30, 2004. 2Assumes reinvestment of all dividends and capital gains distributions, if any, at net asset value. 3Expenses (net of voluntary waiver) are equal to the Fund's annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 366

Hypothetical Example for Comparison Purposes

The table below titled "Based on Hypothetical Total Return" provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund's 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 the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in both the actual and hypothetical total return tables include the service fees effective prior to May 13, 2004. This service fee was reduced May 13, 2004 in order to separately account for the Independent Service Providers costs which, subsequent to May 13, is a flat fee charged directly to each fund. The Independent Service Providers costs are not included in either the actual or hypothetical total return tables. See footnote 4 for a discussion of these costs.

Based on Hypothetical Total Return¹

	Hypothetical Annualized Total Return	Beginning Account Value	Ending Account Value	Annualized Expense Ratio2	Expenses Paid During the Period2
Government Money Market	5.00%	$1,000.00	$1,025.26	0.63%	$3.19
1For the six months ended September 30, 2004. 2Expenses (net of voluntary waiver) are equal to the Fund's annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 366

6. Capital Share Transactions. An unlimited number of capital shares, without par value, are authorized. Transactions in capital shares (in dollars and shares) were as follows:

	Year Ended September 30,
	2004	2003
Shares sold	$15,700,273	$17,610,441
Shares issued in reinvestment of dividends	190,160	222,324
Total shares issued	15,890,433	17,832,765
Shares redeemed	(17,434,633)	(16,912,713)
Net increase (decrease)	$(1,544,200)	$920,052
