Madison Mosaic Income Trust

Management’s Discussion of Fund Performance

ECONOMIC OVERVIEW

We began this one-year period with a welcome calm in the bond markets. The yield curve was relatively stable, market volatility had moderated, and long-term yields remained in a tight trading range. In this environment investors turned their attention to debating economic fundamentals while weighing the sustainability of the recent economic upturn. This atmosphere of calm belied persistent and fundamental economic challenges. The housing market continued to struggle, unemployment was persistently high, and European governments came under pressure. Despite these clouds, higher-risk U.S. bonds continued to lead the market.

Fear reemerged in the financial markets during the second quarter of 2010. After nearly a year of consistent gains from risk sectors (stocks, corporate bonds), turmoil in the European Union among sovereign bond issuers and the banks that finance them caused investors to seek the relative safety of the highest quality investments. In the U.S., that meant a sharp rally in Treasury yields, widening risk premiums on corporate bonds and declines in the broad equity indices. Just as the opening mood of the year had dissipated, this atmosphere of fear proved to be short lived as well.

After three quarters of generally falling long-term bond yields, the market did an about-face in the year’s final quarter. Just as economic indicators began to allay fears of a double-dip recession, the Federal Reserve Board sparked additional confidence with the announcement of another round of quantitative easing, which became known as QE2. While the economy was not actually strong by historic norms, and the recovery remained sub-par, the U.S. was suddenly viewed as the "best of the worst" among major economies. Europe was straddled with sovereign debt concerns, Japan remained mired in a weak growth/high deficit environment, and China was putting on the economic brakes to contain emerging inflation. From the lows in long-term yields in early October, interest rates rose nearly a full percentage point, driving down the value of existing bonds and muting bond returns for the one-year period.

OUTLOOK

At year-end, the U.S. economy showed stronger fundamentals than it did a year previously, and we’ve upgraded our view going forward. The holiday retail season proved a pleasant surprise with retail sales growth exceeding initially gloomy estimates. The manufacturing sector had a firmer tone, and state claims for unemployment insurance resumed their downward trend after a choppy period during the summer. Despite the more buoyant economic mood and our upgraded assessment of future prospects, we still consider the outlook for 2011 to be somewhat below where the economy should be at this stage of the recovery for several reasons.

At year end the housing market remained an issue and exhibited renewed softness with the expiration of tax incentives for home purchase. Mortgage rates edged higher as the year progressed as a result of the general rise in interest rates and the inventory of unsold homes remained near record highs. Housing starts were stuck near the lows recorded in the spring of 2009. Meanwhile, the labor market remained extremely challenging. After a spurt in payroll growth in the spring of 2010, the rate of job growth stalled at a level insufficient to keep the unemployment rate from rising further. Gains in productivity allowed businesses and workers to do more with less, and it is unlikely that payroll growth will advance in earnest until productivity growth levels off.

Despite the jump in bond yields during the fourth quarter, long-term interest rates remain well below our estimate of fair value, and we enter 2011 with a conservative bias. We expect to retain our conservative stance in our fixed income funds in the early part of 2011, and remain watchful for trading opportunities in the volatile environment we see ahead.

MADISON MOSAIC GOVERNMENT FUND

FUND-AT-A-GLANCE

Objective: Madison Mosaic Government Fund provides investors with monthly dividends by investing in bonds and other securities issued or guaranteed by the U.S. Government.

Net Assets: $5.0 million

Date of Inception: July 21, 1983

Ticker: MADTX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Government Fund invests primarily in short to intermediate term government and government agency bonds. The fund concentrates on the intermediate portion of the yield curve with a recognition that the ten-year Treasury bond has offered approximately 90% of the return of a 30-year Treasury with less risk. The fund is actively managed for duration, meaning that when we believe interest rates are falling, we lengthen duration to take advantage of the increased returns that should be available as rates drop. Likewise, when rates appear high, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Madison Mosaic Government Fund returned 3.40% for the annual period ended December 31, 2010. This return underperformed the fund’s benchmark, the Barclays Capital Intermediate Government Bond Index, which had a return of 4.98% for the period. This relative return reflects the fund’s duration posture which tends towards a shorter more defensive stance in a period in which intermediate bonds outperformed short bonds. The fund’s 30-day SEC yield at period end was 0.80%, with an effective duration of 3.22 years.

The Government Fund began the period with 30.6% in Treasuries and 47.8% in government agency notes, with the remainder in mortgage-backed securities and short-term notes. Over the course of the twelve months, management increased the Treasury position to 41.9% while the agency position dropped modestly to a 45.4% weighting. We also trimmed the fund’s holdings in high-quality mortgage-backed securities, decreasing exposure from 19.0% of the fund to 10.9%. The fund’s largest positions during this six-month period were short to intermediate duration bonds issued by the U.S. Treasury, Fannie Mae and Freddie Mac.

MADISON MOSAIC CORE BOND FUND

FUND-AT-A-GLANCE

Objective: Madison Mosaic Core Bond Fund provides relatively higher income by investing in a mix of higher, medium and lower-rated corporate bonds.

Net Assets: $9.1 million

Date of Inception: July 21, 1983

Ticker: MADBX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Core Bond Fund invests primarily in intermediate term corporate, government and mortgage-backed bonds. The fund is actively managed in terms of duration, asset mix and yield curve positioning. When we believe interest rates are falling, we lengthen duration to take advantage of the increased returns that should be available as rates drop. Likewise, when rates appear high, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Mosaic Core Bond Fund rose 5.11% for the year ended December 31, 2010. Over the same period, its benchmark, the Barclays Capital U.S. Intermediate Aggregate Index rose 6.15%. Over the past year the market favored higher-risk, lower-quality securities, while the fund’s conservative duration posture was not additive. Core Bond had a relatively light 7.7% exposure to Baa/BBB bonds (the lowest investment-grade rating) at the beginning of the period and ended the period holding 9.5%. We believe that if the fund had allocated a greater percentage of its portfolio to lower-rated securities throughout the period, its performance relative to its benchmark would have been closer. As of December 31, 2010 Core Bond had a 30-day SEC yield of 2.08% and a duration of 4.15 years.

MADISON MOSAIC INSTITUTIONAL BOND FUND

FUND-AT-A-GLANCE

Objective: The Madison Mosaic Institutional Bond Fund seeks total investment return through a combination of intermediate corporate and government bonds.

Net Assets: $52.4 million

Date of Inception: May 1, 2000

Ticker: MIIBX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Institutional Bond Fund invests primarily in short to intermediate term government, government agency and investment-grade corporate bonds. The fund concentrates on the intermediate portion of the yield curve with a recognition that the ten-year Treasury bond has offered approximately 90% of the return of a 30-year Treasury with less risk. The fund is actively managed for duration, meaning that when we believe interest rates are falling, we lengthen duration to take advantage of the increased returns that should be available as rates drop. Likewise, when rates appear high, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Madison Mosaic Institutional Bond Fund returned 4.35% for the annual period ended December 31, 2010. Over the same period, its benchmark, the Barclays Capital Intermediate Government/Credit Bond Index rose 5.89% Over the one-year period the market favored higher-risk, lower-quality securities, while the fund’s conservative duration posture was not additive. Institutional Bond Fund has a quality mandate which means the fund does not hold high-risk, low-rated bonds. The performance differential among rated bonds can be clearly seen in the one-year returns of the various U.S. Intermediate Bond quality categories as tabulated by Barclays. The highest AAA grade returned 4.8%, BBB returned 9.4%, while the lowest CAA and CA-D produced double-digit returns. Of course, these lower rated bonds contain additional risk, as when we saw their value dive in 2008. We believe that the fund’s quality mandate was a major disadvantage over this period when compared to its benchmark, whose holdings include an allocation to lower quality bonds. As of December 31, 2010 Institutional Bond had an asset allocation of 51.5% corporates, 20.4% government agencies, and 27.1% Treasuries, a 30-day SEC yield of 0.96% and a duration of 3.22 years.

INVESTMENT GRADE CORPORATE BOND FUND

FUND-AT-A-GLANCE

Objective: The Madison Mosaic Investment Grade Corporate Bond Fund provides investors with monthly income by investing in investment grade corporate securities. It is designed to only be available for purchase in broker-sponsored wrap programs.

Net Assets: $1.1 million

Date of Inception: July 1, 2007

Ticker: COINX

Madison Mosaic Investment Grade Corporate Bond Fund provides investors with regular, monthly income through investments in bonds issued by corporations. The fund will generally invest in corporate securities with an average maturity of 10 years or less. The result is a fund designed for investors who seek regular income from an actively managed bond fund that seeks the best risk/return profiles from a portfolio that emphasizes higher quality intermediate-term corporate issuance.

Madison Mosaic Investment Grade Corporate Bond Fund returned 5.81% for the year, during a one-year period in which corporate bonds outperformed U.S. Treasuries and agency bonds. The fund trailed its benchmark, the Barclays Capital Intermediate U.S. Credit Index, which rose 7.76%. The fund focused on higher quality bonds and held a conservative duration posture. Barclays Capital corporate bond indices indicate the quality disparity as their top AAA category returned 4.8% for the year, while the lower categories of BA, B, CAA and CA-D were all up double digits for the period. For the year, long-term bonds outperformed intermediate term bonds which in turn, outperformed short-term bonds. We believe the fund’s more conservative interest rate and quality stance were the primary reasons for its underperformance to the benchmark. At period end, the fund had a 30-day SEC yield of 1.56% and a duration of 3.76 years.

Madison Mosaic Income Trust | December 31, 2010

Notes to Financial Statements

1. Summary of Significant Accounting Policies. Madison Mosaic Income Trust (the "Trust") is registered with the Securities and Exchange Commission under the Investment Company Act of 1940 as an open-end, diversified investment management company. The Trust maintains four separate funds, Madison Mosaic Government Fund, Madison Mosaic Core Bond Fund, Madison Mosaic Institutional Bond Fund and the Madison Mosaic Investment Grade Corporate Bond Fund (known as Corporate Income Shares Fund or COINS prior to November 30, 2010) (collectively, the "Funds"). The Funds are each a diversified mutual fund with their objectives and strategies detailed in their prospectus.

Portfolio Valuation: Repurchase agreements and other securities having maturities of 60 days or less are valued at amortized cost, which approximates market value. Securities having longer maturities, for which quotations are readily available, are valued at the mean between their closing bid and ask prices. Securities for which market quotations are not readily available are valued at their fair value as determined in good faith under procedures approved by the Board of Trustees.

Each fund has adopted the Financial Accounting Standards Board ("FASB") applicable guidance on fair value measurements. Fair value is defined as the price that each fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data "inputs" and minimize the use of unobservable "inputs" and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk (for example, the risk inherent in a particular valuation technique used to measure fair value including such a pricing model and/or the risk inherent in the inputs to the valuation technique). Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below:

Level 1 –quoted prices in active markets for identical investments

Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rate volatilities, prepayment speeds, credit risk, benchmark yields, transactions, bids, offers, new issues, spreads and other relationships observed in the markets among comparable securities, underlying equity of the issuer; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data, etc.)

Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The valuation techniques used by the Funds to measure fair value for the period ended December 31, 2010 maximized the use of observable inputs and minimized the use of unobservable inputs. As of December 31, 2010, none of the Funds held securities deemed as a Level 3.

Please see the Portfolio of Investments for each Fund for a listing of all securities within each caption.

The Funds have adopted the Accounting Standard Update, Fair Value Measurements and Disclosures; Improving Disclosures about Fair Value Measurements which provides guidance on how investment assets and liabilities are to be valued and disclosed. Specifically, the amendment requires reporting entities to disclose i) the input and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements, for Level 2 or Level 3 positions, ii) transfers between all levels (including Level 1 and Level 2) will be required to be disclosed on a gross basis (i.e. transfers out must be disclosed separately from transfers in) as well as the reason(s) for the transfer and iii) purchases, sales, issuances and settlements must be shown on a gross basis in the Level 3 rollforward rather than as one net number. The effective date of the amendment is for interim and annual periods beginning after December 15, 2009, however, the requirement to provide the Level 3 activity for purchases, sales, issuance and settlements on a gross basis will be effective for interim and annual period beginning after December 15, 2010. There were no transfers between classification levels during the period ended December 31, 2010.

In March 2008, FASB issued guidance regarding enhanced disclosures about Funds’ derivitive and hedging activities. Management has determined that there is no impact on the financial statements of the Funds held in the Trust as they did not hold derivative financial instruments during the year.

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

Annual Report - 17

Madison Mosaic Income Trust | Notes to Financial Statements | continued

discount and market discount are accreted over the expected life of each applicable security using the effective interest method. Other income is accrued as earned.

Distribution of Income and Gains: Distributions are recorded on the ex-dividend date. Net invest-ment income, determined as gross investment income less total expenses, is declared as a regular dividend and distributed to shareholders monthly. Capital gain distributions, if any, are declared and paid annually at year-end.

The tax character of distributions paid during 2010 and 2009 was as follows:

	2010	2009
Government Fund:
Distributions paid from:
Ordinary income	$121,062	$114,194
Long-term capital gains	1,819	13,052
Core Bond Fund:
Distributions paid from ordinary income	$357,455	$323,880
Institutional Bond Fund:
Distributions paid from:
Ordinary income	$1,028,225	$173,320
Long-term capital gains	11,212	–
Investment Grade Corporate Bond Fund:
Distributions paid from ordinary income	$46,400	$47,935

As of December 31, 2010, the components of distributable earnings on a tax basis were as follows:

Government Fund:
Accumulated net realized losses	$ –
Net unrealized appreciation on investments	138,419
	$138,419
Core Bond Fund:
Accumulated net realized losses	$ (38,922)
Net unrealized appreciation on investments	276,906
	$237,984
Institutional Bond Fund:
Accumulated net realized gains	$ 59,296
Net unrealized appreciation on investments	1,245,027
	$1,304,323
Investment Grade Corporate Bond Fund:
Accumulated net realized gains	$ 2,314
Net unrealized appreciation on investments	67,127
	$69,441

Net realized gains or losses may differ for financial and tax reporting purposes as a result of loss deferrals related to wash sales and post-October transactions.

Income Tax: No provision is made for federal income taxes since it is the intention of the Trust to comply with the provisions of Subchapter M 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.

As of and during the year ended December 31, 2010, the Funds did not have a liability for any unrecognized tax benefits. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statement of operations. During the period, the Funds did not incur any interest or penalties.

The Regulated Investment Company ("RIC") Modernization Act of 2010 (the "Modernization Act") modernizes several of the federal income and excise tax provisions related to RICs. The Modernization Act contains simplification provisions effective for taxable years beginning after December 22, 2010, which are aimed at preventing disqualification of a RIC for "inadvertent" failures of the asset diversification and/or qualifying income tests. Additionally, the Modernization Act allows capital losses to be carried forward indefinitely, and retain the character of the original loss, exempts RICs from the preferential dividend rule, and repealed the 60-day designation requirement for certain types of pay-through income and gains.

As of December 31, 2010, the Core Bond Fund had available for federal income tax purposes the following unused capital loss carryovers:

Expiration Date	Core Bond Fund
December 31, 2013	$ 6,408
December 31, 2014	22,383
December 31, 2017	10,131

Tax years open to examination by tax authorities under the statute of limitations include 2007 through 2010.

Cash Concentration: At times, the Funds maintain cash balances at financial institutions in excess of federally insured limits. The Funds monitor this credit risk and have not experienced any losses related to this risk.

Use of Estimates: The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to

Annual Report - 18

Madison Mosaic Income Trust | Notes to Financial Statements | continued

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. Investments in Repurchase Agreements. When the Funds purchased securities under agreements to resell, the securities are held for safekeeping by the 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 safekeeping with the Funds’ custodian bank. The Funds, along with other registered investment companies having Advisory and Services Agreements with the same investment adviser, transfer 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. As of December 31, 2010, the Government Fund had a 0.3% interest, the Core Bond Fund had a 1.0% interest, the Institutional Bond Fund had a 0.5% interest and the Investment Grade Corporate Bond Fund had a 0.2% interest in the consolidated repurchase agreement of $16,483,850 collateralized by $16,813,538 in Freddie Mac Mortgaged Backed Security Notes. Proceeds at maturity were $16,483,864.

3. Investment Advisory Fees. For the period covered by this report, the investment adviser to the Funds, Madison Investment Advisors, LLC (the "Adviser"), earned an advisory fee equal to 0.40% per annum of the average net assets of the Government Fund and Core Bond Fund and 0.30% per annum for the Institutional Bond Fund. Effective November 30, 2010, the Investment Grade Corporate Bond Fund’s fee was 0.40% per annum. Prior to November 30, the Investment Grade Corporate Bond Fund was not charged an advisory fee. The fees are accrued daily and are paid monthly. Prior to November 30, 2010, the investment adviser to the Trust was Madison Mosaic, LLC and its parent, Madison Investment Advisors, Inc. On November 30, 2010, Madison Mosaic, LLC changed its name to Madison Investment Advisors, LLC and became the sole Adviser.

4. Investment Transactions. Purchases and sales of securities (excluding short-term securities) for the year ended December 31, 2010 were as follows:

	Purchases	Sales
Government Fund:
U.S. Gov’t securities	$1,741,519	$912,497

Investment Grade Corporate Bond Fund:
U.S. Gov’t securities	$ –	$ –
Other	221,324	140,512

5. Other Expenses. Under a separate Services Agreement, the Adviser will provide or arrange for each Fund to have all other necessary operational and support services for a fee based on a percentage of average net assets. These fees are accrued daily and paid monthly. This fee was 0.28% for the Government Fund, 0.30% for the Core Bond Fund and 0.19% for the Institutional Bond Fund. Effective November 30, 2010, the Investment Grade Corporate Bond Fund’s fee was 0.30%. Prior to November 30, the Investment Grade Corporate Bond Fund was not charged a services fee. The direct expenses paid by the Funds and referenced below come out of this fee.

The Funds pay the expenses of the Funds’ Independent Trustees directly. For the year ended December 31, 2010, these fees were $1,000, $1,000, $1,000 and $0 for the Government, Core Bond, Institutional Bond and Investment Grade Corporate Bond Funds, respectively.

The Funds also pay the expenses of the Funds’ independent registered public accountants directly. For the year ended December 31, 2010, the amounts expensed for these fees were $3,500, $4,000, $6,500 and $0 for the Government, Core Bond, Institutional Bond and Investment Grade Corporate Bond Funds, respectively.

During the year ended December 31, 2010, none of the Funds borrowed on their respective lines of credit.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of Madison Mosaic Income Trust

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments of the Madison Mosaic Income Trust (the "Trust"), including the Government Fund, Core Bond Fund, Institutional Bond Fund and Investment Grade Corporate Bond Fund (formerly the Corporate Income Shares Fund) (collectively, the "Funds"), as of December 31, 2010 and the related statements of operations for the year then ended and the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended and for each of the three years in the period then ended and for the period July 1, 2007 (commencement of operations) through December 31, 2007 for the Investment Grade Corporate Bond Fund. These financial statements and financial highlights are the responsibility of the Trust’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 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust’s internal control over financial reporting. Accordingly we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2010 by correspondence with the Funds’ custodian and brokers. 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 Funds constituting the Trust as of December 31, 2010, and the results of their operations for the year then ended and the changes in their net assets for each of the two years in the period then ended and financial highlights for each of the five years in the period then ended, and for each of the three years in the period then ended and for the period July 1, 2007 (commencement of operations) through December 31, 2007 for the Investment Grade Corporate Bond Fund, in conformity with accounting principles generally accepted in the United States of America.

Fund Expenses

Example: As a shareholder of the Funds, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including Investment advisory fees and other fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds. See Notes 3 and 5 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 July 1, 2010 and held for the six-months ended December 31, 2010.

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
	Beginning Account Value	Ending Account Value	Annualized Expense Ratio	Expenses Paid During the Period2
Government Fund	$1,000.00	$1,001.00	0.69%	$3.48
Core Bond Fund	$1,000.00	$1,005.05	0.70%	$3.60
Institutional Bond Fund	$1,000.00	$1,010.75	0.49%	$2.50
Investment Grade Corporate Bond Fund	$1,000.00	$1,014.73	0.06%3	$0.32
1For the six-months ended December 31, 2010. 2Expenses are equal to the respective 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 365. 3The Investment Grade Corporate Bond Fund did not incur expenses prior to November 30, 2010 when it was known as the Madison Corporate Income Shares Fund.

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 neither 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 either Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the applicable Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Based on Hypothetical Total Return1
	Beginning Account Value	Ending Account Value	Annualized Expense Ratio	Expenses Paid During the Period2
Government Fund	$1,000.00	$1,025.47	0.69%	$3.50
Core Bond Fund	$1,000.00	$1,025.47	0.70%	$3.59
Institutional Bond Fund	$1,000.00	$1,025.47	0.49%	$2.50
Investment Grade Corporate Bond Fund	$1,000.00	$1,025.47	0.06%3	$0.32
1For the six-months ended December 31, 2010. 2Expenses are equal to the respective 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 365. 3Based on the restated annualized expense ratio reflected in the prospectus of the Investment Grade Corporate Bond Fund of 0.70%, the hypothetical expenses paid during the period would have been $3.57.

Discussion of Contract Renewal. The Trustees considered a number of factors when the Board most recently approved the advisory contract between the Adviser and the Trust in July 2010. Rather than providing you with a list of factors or conclusory statements that explained the Board’s decisionmaking process, the following discussion is designed to describe what you would have seen and heard if you had been at the Trust’s Board meeting when it most recently approved the advisory contract:

With regard to the nature, extent and quality of the services to be provided by the Adviser, the Board reviewed the biographies and tenure of the personnel involved in Trust management and the experience of the Adviser and its affiliates as investment manager to other investment companies with similar investment strategies. They recognized the wide array of investment professionals employed by the firm. Representatives of the Adviser discussed the firm’s ongoing investment philosophies and strategies intended to provide superior performance consistent with each Trust portfolio’s investment objectives under various market scenarios. The Trustees also noted their familiarity with the Adviser and its affiliates due to the Advisers’ history of providing advisory services to the Madison Mosaic organization as well as the MEMBERS Mutual Funds, Ultra Series Fund and the Madison Strategic Sector Premium Fund.

The Board also discussed the quality of services provided to the Trust by its transfer agent and custodian as well as the various administrative services provided directly by the Adviser.

With regard to the investment performance of the Trust and the investment adviser, the Board reviewed current performance information provided in the written Board materials. They discussed the reasons for both outperformance and underperformance compared with peer groups and applicable indices and benchmarks.

A comprehensive discussion of fund performance and market conditions followed. Representatives of the Adviser

Annual Report - 24

Madison Mosaic Income Trust | Other Information | continued

discussed with the Board the methodology for arriving at peer groups and indices used for performance comparisons.

With regard to the costs of the services to be provided and the profits to be realized by the investment adviser and its affiliates from the relationship with the Trust, the Board reviewed their expense ratios for a variety of other funds in each Trust portfolio’s peer group with similar investment objectives.

The Board noted that the Adviser or its affiliates provided investment management services to other investment company and non-investment company clients and considered the fees charged by the Adviser to such funds and clients for purposes of determining whether the given advisory fee was disproportionately large under the so-called "Gartenberg" standard traditionally used by investment company boards in connection with contract renewal considerations. The Board took those fees into account and considered the differences in services and time required by the various types of funds and clients to which the Adviser provided services. The Board recognized that significant differences may exist between the services provided to one type of fund or client and those provided to others, such as those resulting from a greater frequency of shareholder redemptions in a mutual fund and the higher turnover of mutual fund assets. The Board gave such comparisons the weight that they merit in light of the similarities and differences between the services that the various funds require and were wary of "inapt comparisons." They considered that, if the services rendered by the Adviser to one type of fund or client differ significantly from others, then the comparison should not be used. In the case of non-investment company clients for which the Adviser may act as either investment adviser or subadviser, the Board noted that the fee is lower than the fee charged to the Trusts. The Board noted too the various administrative, operational, compliance, legal and corporate communication services required to be handled by the Adviser which are performed for investment company clients but are not performed for other institutional clients.

The Trustees reviewed each fund’s fee structure based on total fund expense ratio as well as by comparing advisory fees to other advisory fees. The Board noted the simple expense structure maintained by the Trusts (i.e. an advisory fee and a capped administrative "services" expense). The Board paid particular attention to the total expense ratios paid by other funds with similar investment objectives, recognizing that such a comparison, while not completely dispositive, was nevertheless an important consideration.

The Trustees sought to ensure that fees paid by the Trust were appropriate. The Board reviewed materials demonstrating that although the Adviser is compensated for a variety of the administrative services it provides or arranges to provide to the Trust pursuant to its Services Agreement with the Trust, such compensation generally does not cover all costs due to the cap on administrative expenses. Administrative, operational, regulatory and compliance fees and costs in excess of the Services Agreement fees are paid by the Adviser from investment advisory fees earned. In this regard, the Trustees noted that examination of each Trust portfolio’s total expense ratio compared to those of other investment companies was more meaningful than a simple comparison of basic "investment management only" fee schedules.

In reviewing costs and profits, the Board noted the salaries of all portfolio management personnel, trading desk personnel, corporate accounting personnel and employees of the Adviser who serve as Trust officers, as well as facility costs (rent), could not be supported by fees received from the Trust alone. However, the Board recognized that the Trust is profitable to the Adviser because such salaries and fixed costs are already paid in whole or in part from revenue generated by management of the remaining assets managed by the Adviser. The Trustees noted that total assets managed by the Adviser and its affiliates approximated $15 billion at the time of the meeting. As a result, although the fees paid by each Trust portfolio at its present size might not be sufficient to profitably support a stand-alone fund, the Trust is reasonably profitable to the Adviser as part of its larger, diversified organization. In sum, the Trustees recognized that each Trust is important to the Adviser, is managed with the attention given to other firm clients and is not treated as "loss leader."

With regard to the extent to which economies of scale would be realized as each Trust portfolio grows, the Trustees recognized that at their current sizes, it was premature to discuss any economies of scale not already factored into existing advisory and services agreements.

Annual Report - 25

Madison Mosaic Income Trust | Other Information | concluded

Counsel to the Trust’s non-interested Trustees (the "Independent Trustees") confirmed that the Independent Trustees met previously and reviewed the written contract renewal materials provided by the Adviser. The Independent Trustees’ counsel noted that the Independent Trustees had considered such materials in light of the aforementioned Gartenberg standards as well as criteria either set forth or discussed in the recent Supreme Court decision in Jones v. Harris regarding the investment company contract renewal process under Section 15(c) of the Investment Company Act of 1940, as amended. The Independent Trustees made a variety of additional inquiries regarding such written materials to the Adviser and representatives of the Adviser discussed each matter raised.

After further discussion and analysis and reviewing the totality of the information presented, including the information set forth above and the other information considered by the Board of Trustees, the Trustees concluded that the Trust’s advisory fees are fair and reasonable for each respective portfolio and that renewal of their respective Advisory and Services Agreements with the Madison Investment Advisors organization are in the best interests of each respective fund and its shareholders.
