Management’s Discussion of Fund Performance

2011 IN REVIEW

A quick glance at the 2011 returns of the major domestic investment indices might suggest a benign and uneventful year for stock investors. The S&P 500, considered a benchmark for the U.S. domestic stock market, was virtually flat for the year, with dividend income responsible for almost all of the 2.1% positive total return. In contrast, the overall domestic bond market, as measured by the Barclays Capital Aggregate Index was up a solid 7.8%. However, the markets were very volatile during the year. The overseas indices provide a hint at some of the most important dislocations that were occurring behind these domestic stock and bond returns. The MSCI EAFE Index, which is a widely used proxy for stock markets outside the U.S., slid -11.7% for the year, while emerging markets were hit hard, as shown by the MSCI Emerging Markets Index, which was down -18.4% for 2011. The volatility U.S. investors actually experienced is evident in the return of the S&P 500 from its 2011 high on April 29 to its low on October 3; a period in which the Index lost -18.6%. Bond investors experienced a massive Treasury rally as the yield on the 10-Year Treasury reached 3.7% on February 8 before dropping by more than half to its record-setting closing low of 1.7% on September 22.

In the U.S., 2011 began with considerable optimism as stock indices rose briskly in the first quarter and investors shifted away from low-risk, low-yielding bonds. The yield on the 10-Year Treasury rose during this period, hitting 3.74% on February 8, which proved to be the high for the year. This optimism was fueled by economic growth which seemed sustainable, while corporate earnings, balance sheets and profits appeared strong. But these positives were tested by geo-political events and slower economic data in the summer. The first blow in 2011 came with the chain reaction of freedom movements in the Middle East. Change and uncertainty, especially when you throw in rising oil prices, tend to drive investors towards less risky investments, and this proved to be a plus for the Treasury market and other high-quality bonds. The tragic earthquake and tsunami in Japan followed and the markets suffered along with the realization of how much damage was done to one of the world’s largest economies.

For much of the rest of the 2011, stock prices waxed and waned as news flowed out of Europe. This news caused volatility to remain high and investors showed a preference for the perceived safety of bonds, particularly U.S. Treasuries. The yield on the 10-Year Treasury hit an all-time closing low of 1.72% on September 22, and finished the year at 1.88%. In addition, the flight to safety was supported by the mid-year stalemate in Washington over the U.S. deficit, which seemed to drag on endlessly. This impasse eventually sparked Standard & Poor’s landmark downgrade of U.S. debt on August 6. But the downgrade couldn’t stem the flight to safety, as demand continued to push Treasury yields lower. In late September the Federal Reserve announced addition action to stimulate the economy, with this round focused on buying longer-term bonds. The combination of fear generated by global events and Fed intervention produced what we felt was an artificial boost to the bond market by keeping rates lower than our assessment of fundamental value. In the end the broader bond indices, such as Barclays Aggregate soundly outperformed the broader stock indices for the year.

OUTLOOK

Looking forward, we are impressed with the resiliency of the U.S. economy. Still, we expect below-average economic growth for 2012 as the debt deleveraging process continues. Many of the cautionary macroeconomic issues that existed at the start of 2011 still persist: weak housing, strained government budgets, and stagnant wage growth. Europe remains a major concern, and the progression of the debt crisis abroad appears likely to lead to continued periods of "risk on" and "risk off" for global financial markets. All told, we believe volatility is here to stay until the heightened level of global uncertainty begins to subside.

For the bond market, we anticipate a return to a focus on fundamentals rather than the sound bite of the day – an emphasis on facts rather than fear. When this happens bond investors should be prepared for a possible rise in rates, a trend which can put pressure on bonds, particularly long bonds. As active managers, we seek to cushion our investors from interest rate risk, while remaining poised to take advantage of the higher yields which could come out of such a scenario.

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: $5.3 million

Date of Inception: July 21, 1983

Ticker: MADTX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Mosaic 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 will fall, we lengthen duration to take advantage of the increased returns that should be available as rates drop. Likewise, when rates appear likely to rise, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Madison Mosaic Government Fund returned 3.65% for the annual period ended December 3, 2011. This return exceeded the fund’s Morningstar Short Government peer group, which had a category return of 2.09% for the period, but trailed the Barclays Capital Intermediate Government Bond Index, which returned 6.08%. These relative returns reflect primarily the fund’s duration posture which tended towards a more intermediate stance than the Morningstar category, while being shorter than the Barclays Index in a year in which long-term bonds soundly outperformed shorter bonds. The unmanaged Barclays Index, which has no expenses associated with it, held a duration of 3.79 years at year-end, compared to the fund’s 3.02. A secondary, but also important, influence on relative returns was asset allocation among government bonds. Madison Mosaic Government Fund favored the yield advantage in U.S. Government Agency bonds throughout the year over Treasury securities. However, Treasuries outperformed agencies as seen by the relative returns of the Barclays Intermediate U.S. Agency Index, which was up 3.70%, compared to the Barclays Intermediate U.S. Treasury Index, which advanced 6.57%, a reflection on the general flight to safety which was characteristic of investor behavior across the year. At year-end, the Government Bond Fund held 48.3% U.S. Government agency bonds, 37.3% in Treasuries, 10.8% in mortgage-backed bonds, and 3.6% in cash and other assets. The fund held 38 positions and had a 30-day SEC yield of 0.43%.

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: $8.8 million

Date of Inception: July 21, 1983

Ticker: MADBX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Mosaic 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 likely to fall, we lengthen duration to take advantage of the increased returns that should be available as rates drop. Likewise, when rates appear likely to rise, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Mosaic Core Bond Fund rose 6.60% for the year ended December 31, 2011. Over the same period, its Morningstar peer group in the Intermediate Term Bond category averaged 5.86%, while Barclay’s Capital Aggregate Bond Index rose 7.84%. In a year in which long bonds outperformed short bonds, the fund had solid performance, despite holding a more conservative, shorter duration than its Barclays Index. At year-end, the Barclays Aggregate Index held a duration of 4.95 years, compared to Core Bond’s 4.12 years. In terms of peer performance, one likely advantage was the fund’s preference for higher-quality bonds, and management’s decision to favor industrial corporate bonds over bonds issued by the financial firms. Investors favored more secure bonds in 2011, particularly U.S. Treasury issuance, while the sovereign debt crisis in Europe cast a pall over credit-sensitive U.S. financial companies. At year-end, the fund held 50.5% in corporate bonds, 21.3% in Treasuries, 21.1% in mortgage-backed bonds, 3.3% in government agency notes, and 3.8% in cash and other assets. The credit quality of the bond portfolio was high, with 48.8% sporting a Standard & Poor’s rating of AAA, 13.2% AA, 31.7% A, and 6.3% BBB, with no exposure to lower-rated bonds. The fund ended the period with a 30-day SEC yield of 1.66%.

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: $104.8 million

Date of Inception: May 1, 2000

Ticker: MIIBX

INVESTMENT STRATEGY HIGHLIGHTS

Madison Mosaic 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 low, we shorten portfolio maturities with the goal of limiting potential declines.

PERFORMANCE DISCUSSION

Madison Mosaic Institutional Bond Fund returned 3.53% for the annual period ended December 31, 2011. Over the same period, its Morningstar peer group in the Intermediate Term Bond category averaged 5.86%, while the Barclays Capital Intermediate Government Credit Index returned 5.80%. Over the one-year period, the market favored higher-quality, longer-dated issues. While the fund’s quality bias was a plus, it wasn’t enough to cancel the powerful effect of dropping interest rates, which boosted the value of long-term bonds. This can clearly be seen in the returns of the various Morningstar category returns: Long Term 11.47%, Short Term 1.66% and High Yield 2.83%. We believe that the fund’s conservative, relatively short duration posture was a major disadvantage over this period when compared to our benchmark, and was likely the major distinction against our peer group, whose durations tend to be closer to the benchmark. At year-end, the Barclays Intermediate Government Credit Index held a duration of 3.97 years, compared to Institutional Bond’s 2.79 years. As of December 31, 2011, Institutional Bond had an asset allocation of 48.5% corporates, 13.3% government agencies, 33.7% Treasuries and 4.5% cash and other assets, and a 30-day SEC yield of 0.57%.

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.

Net Assets: $17.6 million

Date of Inception: July 1, 2007

Ticker: COINX

Investment Strategy Highlights

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.

Performance Discussion

Madison Mosaic Investment Grade Corporate Bond Fund returned 7.83% for the annual period ended December 31, 2011, during a strong year for bonds. Over this same period, the fund’s Morningstar peer group, Intermediate Bond, returned 5.86%, while the Barclays Capital Credit Bond Index returned 8.35%. Given that the Barclays Index is unmanaged and incurs no expenses, the fund’s results were highly comparable to the index, even though it had a slight disadvantage of a shorter duration stance, as indicated by the fund’s year-end duration of 6.20 years, and the index’s 6.74 years. One plus was its high-quality bias in a year in which high-quality bonds outperformed low-quality bonds, and the fund’s security selection, which emphasized industrial issuance over the troubled financial sector. It was likely that the relatively long duration posture of the fund, its avoidance of low-quality bonds, and the relative strength of corporate bonds over agency and mortgage-backed securities all contributed to the fund’s strong performance against its Morningstar peer group. At year-end, the fund’s quality exposure according to Standard and Poor’s was 1.7% AAA, 20.4% AA, 47.1% A, and 30.8% BBB. The fund held 64 issues and had a 30-day SEC yield of 2.11%.

Madison Mosaic Income Trust

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 (collectively, the "Funds"). Each Fund is a diversified mutual fund with its objectives and strategies detailed in its 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, 2011 maximized the use of observable inputs and minimized the use of unobservable inputs.

The following is a summary of the inputs used as of December 31, 2011 in valuing the Funds’ investments carried at fair value:

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

There were no transfers between classification levels during the period ended December 31, 2011. As of and during the year ended December 31, 2011, none of the Funds held securities deemed as a Level 3.

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.

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Udpate ("ASU") No. 2011-04, modifying Topic 820, Fair Value Measurements and Disclosures. At the same time, the International Accounting Standards Board ("IASB") issued International Financial Reporting Standard ("IFRS") 13, Fair Value Measurement. The objective by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. The effective date of the ASU is for Interim and annual periods beginning after December 15, 2011 and therefore not effective for the current fiscal year. The Funds’ investment adviser is in the process of assessing the impact of the updated standards on the Funds’ financial statements.

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. 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.

Annual Report | December 31, 2011 | 21

Madison Mosaic Income Trust | Notes to Financial Statements | continued

The tax character of distributions paid during 2011 and 2010 was as follows:

	2011	2010
Government Fund:
Distributions paid from:
Ordinary income	$106,536	$121,062
Long-term capital gains	31,029	1,819
Core Bond Fund:
Distributions paid from ordinary income	$248,028	$357,455
Institutional Bond Fund:
Distributions paid from:
Ordinary income	$1,073,254	$1,028,225
Long-term capital gains	20,987	11,212
Investment Grade Corporate Bond Fund:
Distributions paid from:
Ordinary income	$69,098	$46,400
Long-term capital gains	$22,199	–

As of December 31, 2011, the components of distributable earnings on a tax basis were as follows:

Government Fund:
Accumulated net realized gains	$ 2,343
Net unrealized appreciation on investments	183,176
	$185,519
Core Bond Fund:
Accumulated net realized losses	$ (27,287)
Net unrealized appreciation on investments	538,633
	$511,346
Institutional Bond Fund:
Accumulated net realized losses	$ (52,876)
Net unrealized appreciation on investments	2,500,454
	$2,447,578
Investment Grade Corporate Bond Fund:
Net unrealized appreciation on investments	$214,681
	$214,681

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, 2011, 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.

Tax years open to examination by tax authorities under the statute of limitations include 2008 through 2011.

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, 2011, the Core Bond Fund and Institutional Bond Fund had available for federal income tax purposes the following unused capital loss carryovers:

Fund	Short-Term Losses	Long-Term Losses	Expire
Core Bond	$17,156	–	December 31, 2014
	10,131	–	December 31, 2017
Institutional Bond	–	$52,876	Do not expire.

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 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 purchase 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. Pursuant to an exemptive order issued by the Securities and Exchange Commission, 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, 2011, the Government Fund had a 0.7% interest, the Core Bond Fund had a 1.0% interest, the Institutional Bond Fund had a 30.1% interest and the Investment Grade Corporate Bond Fund had a 1.2% interest in the consolidated repurchase agreement of $24,892,514 collateralized by $25,389,217 in Fannie Mae Mortgaged Backed Security Notes. Proceeds at maturity were $24,892,521.

In April 2011, FASB issued ASU No. 2011-03 "Reconsideration of Effective Control of Repurchase Agreements." ASU 2011-03 is an amendment to Topic 860 "Transfers and Servicing." These amendments simplify the accounting for repurchase agreements by eliminating the requirement that the transferor demonstrate it has adequate collateral to fund substantially all the cost of purchasing replacement assets. As a result, more arrangements could be accounted for as secured borrowings rather than sales. The guidance applies to public and nonpublic companies and is effective for interim and annual reporting periods beginning on or after December 15, 2011. The guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. At this time, management is evaluating the implications of ASU 2011-03 and its impact on the financial statements.

3. Investment Advisory Fees. 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, Core Bond Fund and Investment Grade Corporate Bond Fund and 0.30% per annum for the Institutional Bond Fund.

4. 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. For the year ended December 31, 2011, this fee was 0.28% for the Government Fund, 0.30% for the Core Bond Fund, 0.19% for the Institutional Bond Fund and 0.30% for the Investment Grade Corporate Bond Fund. The Independent Trustees fees and the expenses of the Funds’ independent registered public accountants are paid out of this fee.

5. Investment Transactions. Purchases and sales of securities (excluding short-term securities) for the year ended December 31, 2011 were as follows:

8. Line of Credit. The Government Fund, Core Bond Fund and Institutional Bond Fund have lines of credit with U.S. Bank, N.A. of $500,000, $1 million and $5 million, respectively. Each line is a revolving credit facility with a bank for temporary emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The interest rate on the outstanding principal amount is equal to the prime rate less 1/2%. Each Fund paid $250 for the year to maintain its line of credit. During the year ended December 31, 2011, the Government Fund and Core Bond Fund drew $63,000 and $44,000 for one day on their credit facility and paid $5 and $3 of interest, respectively.

9. Subsequent Events. On February 9, 2012, the Board of Trustees approved the creation of R6 shares for the Core Bond Fund. The additional share class will begin to be offered through certain distribution channels on March 1, 2012. No other events have taken place that meet the definition of a subsequent event that requires adjustment to, or disclosure in the financial statements.

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 (collectively, the "Funds"), as of December 31, 2011 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 four 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 audits 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, 2011 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, 2011, 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 four 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 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 July 1, 2011 and held for the six-months ended December 31, 2011.

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	$1,022.15	0.69%	$3.50
Core Bond Fund	$1,000.00	$1,040.62	0.70%	$3.63
Institutional Bond Fund	$1,000.00	$1,019.74	0.49%	$2.49
Investment Grade Corporate Bond Fund	$1,000.00	$1,054.82	0.69%	$3.58
1For the six-months ended December 31, 2011. 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.

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 any 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 a 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	0.69%	$3.47
1For the six-months ended December 31, 2011. 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.

Discussion of Contract Renewal (Unaudited). The Trustees considered a number of factors when the Board approved the renewal of the advisory contract between the Adviser and the Trust during its meeting in July 2011. Rather than providing you with a list of factors or conclusory statements that explained the Board’s decision-making 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 renewed the Trust’s 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 portfolio management and the experience of the Adviser and its affiliates as investment manager to other investment companies with similar investment strategies or to individual clients or institutions with similar investment strategies. They recognized the wide array of investment professionals employed by the respective firm or firms. 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 its proprietary investment company clients.

The Board also discussed the quality of services provided to the Trust by its applicable transfer agent, fund administrator and custodian as well as the various administrative services provided directly by the Adviser. Such services included arranging for third party service providers to provide all necessary administration.

With regard to the investment performance of the Trust and the 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. They reviewed both long-term and short-term performance. The Board and representatives of the Adviser engaged in a comprehensive

28 | Annual Report | December 31, 2011

Madison Mosaic Income Trust | Other Information | continued

discussion of performance and market conditions. Representatives of the Adviser 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 Adviser and its affiliates from the relationship with the Trust, the Board reviewed the expense ratios for a variety of other funds in each Fund’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/or 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 differed 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 may be lower than the fee charged to the Trust. 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 expense ratio as well as by comparing advisory fees to other advisory fees. The Board noted the simple expense structure maintained by the Trust (i.e. an advisory fee and a capped administrative "services" expense). The Board noted the total expense ratios paid by other funds with similar investment objectives, recognizing that such a comparison, while not dispositive, was 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 and other investment companies pursuant to its administrative services agreements with the Trust (or series, as the case may be), such compensation does not always 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 the 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 that for some smaller portfolios, 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 such portfolios alone. However, the Board recognized that the Trust, along with the other funds in the Madison Mosaic and other proprietary mutual fund families in the Madison organization, are profitable to the Adviser because such salaries and fixed costs are already paid in whole or in part from revenue generated by management of other client assets managed by the Adviser. The Trustees noted that total assets managed by the Adviser and its affiliates approximated $16 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 the Trust is important to the Adviser and is managed with the attention given to the Adviser’s other clients.

Annual Report | December 31, 2011 | 29

Madison Mosaic Income Trust | Other Information | concluded

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.

During the meeting, the Independent Trustees were represented by Independent counsel, who confirmed that the Trust’s Independent Trustees met separately to review a variety of written contract renewal materials provided by the Adviser. 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.

Finally, the Board also reviewed the Trust’s distribution agreements and the information provided in the written materials regarding the distributor as well as applicable Codes of Ethics.

After further discussion, analysis and review of the totality of the information presented, including the information set forth above and the other information considered by the Board of Trustees, the Trustees, including the Independent 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 are in the best interests of each respective Trust portfolio and its shareholders.
