Management’s Discussion of Fund Performance

PERIOD IN REVIEW

Despite modest economic growth, U.S. equities had one of the best years in history and led the world’s stock markets, as the S&P 500 Index advanced 32.39% in 2013. Domestic mid-cap and small-cap indices showed even stronger returns, with the Russell Midcap® Index up 34.76% and the Russell 2000® Index of small-cap stocks up 38.82%. Developed international markets were also robust, as the broad MSCI EAFE Net Index advanced 22.78%. Emerging markets, on the other hand, lagged the developed world badly, with the Russell Emerging Market Index barely positive with a 0.29% return.

Despite an array of challenges, the resilient U.S. economy grew by nearly 2% in 2013, with the rate of this growth appearing to accelerate through the final quarters. Europe seemed to be working through the worst of its problems, while emerging markets showed signs of slowing growth, putting selling pressure on what had been an investor favorite for much of the past decade.

Returns for bond investors were not as satisfying, as the broad Barclays U.S. Aggregate Bond Index dropped -2.02%. During the final quarter of 2013, fixed income investors continued to focus on the timing of a much awaited shift in monetary policy from the Federal Reserve. Throughout 2013 strengthening economic fundamentals and hints from the Federal Reserve Board created expectations for a tapering in Fed open-market bond purchasing. These expectations for what was widely viewed as the first stage towards monetary tightening put steady pressure on interest rates. The yield on the bellwether 10-year Treasury note began the year below 2% and climbed close to 3% in early September before drifting back to 2.6% at the end of the third quarter. At year’s end the 10-year yield was just over 3%, marking its highest level for 2013.

OUTLOOK

In our view, this encouraging display of economic persistence bodes well for 2014. Our cautiously upbeat outlook is largely based on an improving fiscal backdrop, with 2013’s federal government headwind expected to recede in 2014. We are impressed by the improvement in the U.S. economy. Relative to other countries, the U.S. enjoys favorable demographics, has strong energy and agricultural resources, and a robust consumer base. In addition, the U.S. federal budget deficit has declined from 10% to near 4% of GDP over the past four years. We remain watchful regarding still-high debt levels with governmental entities and consumers, lower labor force participation, unclear long-

term fiscal and monetary policies, and lower levels of capital investments by businesses. On balance, though, the U.S. looks strong compared to the rest of the world.

CONSERVATIVE ALLOCATION FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Conservative Allocation Fund invests primarily in shares of registered investment companies (the “underlying funds”). The fund will be diversified among a number of asset classes and its allocation among underlying funds will be based on an asset allocation model developed by Madison Asset Management, LLC (“Madison”), the fund’s investment adviser.

The team may use multiple analytical approaches to determine the appropriate asset allocation, including:

• Asset allocation optimization analysis – considers the degree to which returns in different asset classes do or do not move together, and the fund’s aim to achieve a favorable overall risk profile for any targeted portfolio return.

• Scenario analysis – historical and expected return data is analyzed to model how individual asset classes and combinations of asset classes would affect the fund under different economic and market conditions.

• Fundamental analysis – draws upon Madison’s investment teams to judge each asset class against current and forecasted market condi-tions. Economic, industry and security analysis is used to develop return and risk expectations that may influence asset class selection.

In addition, Madison has a flexible mandate which permits the fund, at the sole discretion of Madison, to materially reduce equity risk exposures when and if conditions are deemed to warrant such an action.

PERFORMANCE DISCUSSION

The Ultra Series Conservative Allocation Fund (Class I) returned 7.61% over the 12-month period, underperforming the Conservative Allocation Fund Custom Index return of 8.54%, but slightly outperforming the Morningstar Conservative Allocation category average return of 7.23%. The two greatest positive contributors to performance were the fund’s relative overweight to U.S. stocks within the equity allocation, and a below-benchmark duration within the fixed income portion of the portfolio. The broad U.S. stock market (Russell 3000® Index) outperformed the international market (MSCI EAFE Index) by approximately 10% over the period. Bonds were hurt by a significant rise in interest rates since the end of 2012. The yield on the bellwether 10-year Treasury note began the year below 2% and climbed to just over 3% by year’s end. The fund’s modest duration and floating rate holdings served to mitigate the losses within the fixed income portion of the fund. The two most negative detractors from performance were the fund’s underweighting to small-cap stocks and weak selection among core U.S. equity positions where Madison’s preference for managers holding more proven, high-quality companies was out of favor with a speculative market. These negative factors outweighed the positive factors and resulted in underperformance compared to the benchmark, but not the peer category for the year.

MONEY MARKET FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Money Market Fund invests exclusively in U.S. dollar-denominated money market securities maturing in thirteen months or less from the date of purchase. These securities will be obligations of the U.S. Government and its agencies and instrumentalities, but may also include securities issued by U.S. and foreign financial institutions, corporations, municipalities, foreign governments, and multi-national organizations, such as the World Bank. The fund may invest in mortgage-backed and asset-backed securities, including those representing pools of mortgage, commercial, or consumer loans originated by financial institutions.

CORE BOND FUND

INVESTMENT STRATEGY HIGHLIGHTS

Under normal circumstances, the Ultra Series Core Bond Fund invests at least 80% of its net assets in bonds. To keep current income relatively stable and to limit share price volatility, the fund emphasizes investment grade securities and maintains an intermediate (typically 3-7 year) average portfolio duration, with the goal of being between 85-115% of the market benchmark duration. The fund also strives to add incremental return in the portfolio by making strategic decisions relating to credit risk, sector exposure and yield curve positioning. The fund may invest in corporate debt securities, U.S. Government debt securities, foreign government debt securities, non-rated debt securities, and asset-backed, mortgage-backed and commercial mortgage-backed securities.

U.S. Government and Agency Obligations	49.5	%
Short-Term Investments and Other Net Assets and Liabilities	2.1	%

PERFORMANCE DISCUSSION

The Ultra Series Core Bond Fund (Class I) outperformed its benchmark, but had a negative return of -2.24% for the 12-month period, in which bonds suffered broadly in the face of rising interest rates. The yield on the bellwether 10-year Treasury note began the year below 2% and climbed to just over 3% by year’s end. Rising rates depress the value of existing, lower-yielding bonds. The fund’s benchmark index, the Bank of America Merrill Lynch U.S. Corporate, Government and Mortgage Index produced a loss of -2.34% for the period. The fund had the advantage of a shorter relative duration than its benchmark, with less exposure to the long-end of the yield curve where losses were most pronounced. On the other hand, the short duration stance meant less yield than the index, which has a negative impact on total return. An underexposure to low-quality, high-yield bonds was a detriment as CAA rated junk bonds were the bond market leaders. Overall, the shorter duration resulted in fund outperformance relative to its benchmark for the year.

HIGH INCOME FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series High Income Fund invests primarily in lower-rated, higher-yielding income bearing securities, such as “junk” bonds. Because the performance of these securities has historically been strongly influenced by economic conditions, the fund may rotate securities selection by business sector according to the economic outlook. Under normal market conditions, the fund invests at least 80% of its net assets in bonds rated lower than investment grade (BBB/Baa) and their unrated equivalents or other high-yielding securities.

PERFORMANCE DISCUSSION

The Ultra Series High Income Fund (Class I) had strong absolute returns for the 12-month period, with a gain of 5.49%. This trailed its benchmark, the Bank of America Merrill Lynch U.S. High Yield Master II Constrained Index, which advanced 7.41%. While most bond sectors showed negative returns in 2013 in the wake of rising interest rates, high yield bonds were the exception. Investors continued to be attracted to their excess yield, while an improving U.S. economy buoyed confidence in corporate prospects. Based on Barclays Capital Bond Indices, intermediate corporate bonds rated in the top AAA to A classes all had small losses in 2013, while BA-rated bonds rose 5.1%, B-rated 7.5%, and CAA-rated led the market with a 13.4% gain. The fund’s returns were somewhat constrained by management’s relative quality bias and preference for bonds from more conservative industry sectors, especially Health Care, resulting in the overall underperformance against the benchmark for the year.

Ultra Series Fund | Management’s Discussion of Fund Performance  | December 31, 2013

DIVERSIFIED INCOME FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Diversified Income Fund seeks income by investing in a broadly diversified array of securities including bonds, common stocks, real estate securities, foreign market bonds and stocks and money market instruments. Bonds, stock and cash components will vary, reflecting the portfolio managers’ judgments of the relative availability of attractively yielding and priced stocks and bonds. Generally, however, bonds will constitute up to 80% of the fund’s assets, stocks will constitute up to 60% of the fund’s assets, real estate securities will constitute up to 25% of the fund’s assets, foreign stocks and bonds will constitute up to 25% of the fund’s assets and money market instruments will constitute up to 25% of the fund’s assets. Under normal market conditions, the fund intends to limit the investment in lower credit quality bonds to less than 50% of the fund’s assets. The balance between the two strategies of the fund (fixed income and equity investing) is determined after reviewing the risks associated with each type of investment, with the goal of meaningful risk reduction as market conditions demand.

PERFORMANCE DISCUSSION

The Ultra Series Diversified Income Fund (Class I) outperformed its blended benchmark with a return of 16.07% for the 12-month period. This 50% stock, 50% bond benchmark had a return of 13.90%, combining the Bank of America Merrill Lynch U.S. Corporate Government and Mortgage Index’s -2.34% return with S&P 500 Index’s 32.39% return. The equity portion of the portfolio was in line with the broader index, as value stocks trailed growth stocks only slightly over the period. The stock portfolio had its best relative returns in the Industrials sector, where an overweighting to an index-beating sector was supported by strong returns by 3M, Boeing, UPS and United Technologies. On the other hand, the rapidly rising market left many of the more defensive positions behind, and this was particularly true in Consumer Staples, where an above-index exposure and holdings in Philip Morris, Sysco and Coca-Cola trailed the market. The bond allocation suffered a negative return in face of broad bond market losses over the year but outperformed its benchmark due to a shorter, more conservative duration stance and a lighter exposure to financial and mortgage-based bonds, which had sharper declines than the overall market.

LARGE CAP VALUE FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Large Cap Value Fund will, under normal market conditions, maintain at least 80% of its net assets in large cap stocks. The fund follows a “value” approach, meaning the portfolio managers seek to invest in stocks at prices below their perceived intrinsic value as estimated based on fundamental analysis of the issuing company and its prospects. By investing in value stocks, the fund attempts to limit the downside risk over time but may also produce smaller gains than other stock funds if their intrinsic values are not realized by the market or if growth-oriented investments are favored by investors. The fund will diversify its holdings among various industries and among companies within those industries.

PERFORMANCE DISCUSSION

The Ultra Series Large Cap Value Fund (Class I) returned 30.07% for the twelve-month period, underperforming the Russell 1000® Value Index, which advanced 32.53%. The largest lag in terms of sector performance was in Materials, where the fund experienced a negative return against the Index’s positive results, as Newmont Mining was punished when the price of gold plummeted, and The Mosaic Company was hit by unexpected price cuts from foreign competitors. Other drags on performance included the fund’s three Materials Sector stocks, which had negative results for the period. The fund‘s holdings in cash, which is necessary for fund operations, was also a detriment in a rapidly rising market. IBM was the largest detractor in Technology. The fund had particularly strong results in the index-beating Industrials Sector, where a higher exposure and excellent results from 3M, Boeing, UPS and United Technologies. The fund also had excellent results in Consumer Discretionary, led by communications stocks Viacom, Time Warner and Omnicom. Overall, the burden on performance outweighed the strongly performing positives, which resulted in underperformance against the benchmark.

LARGE CAP GROWTH FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Large Cap Growth Fund invests primarily in common stocks of larger companies and will, under normal market conditions, maintain at least 80% of its net assets in large cap stocks. Stocks selected for the fund will represent primarily well-established companies that have a demonstrated pattern of consistent growth. To a lesser extent, the fund may invest in less established companies that may offer more rapid growth potential. The fund has an active trading strategy which will lead to more portfolio turnover than a more passively-managed fund.

PERFORMANCE DISCUSSION

The Ultra Series Large Cap Growth Fund (Class I) returned 30.51% for the 12-month period, underperforming the Russell 1000® Growth Index, which advanced 33.48%. This was a period in which lower-quality, more financially leveraged companies showed better returns than higher-quality companies with strong balance sheets, which we as fund manager, favor. Another related headwind for the fund was sector allocation, as the fund was underweight one of the S&P 500’s best-performing sectors, Health Care. However, stock picking made up the difference, led by biotechs Biogen Idec and Celgene. The main detriment for the period was not stock picking or sector allocation, but the holding of cash in such a strong market, which contributed more than three-fourths of the fund’s underperformance. While holding some cash is generally part of prudent management of liquidity in a mutual fund, rapidly rising valuations during this period made it increasingly difficult for us to find attractive entry points for investing. In such circumstances we typically are pa-tient, waiting for more opportune times to invest, and cash positions can rise. The fund had its worst relative performance in Con-sumer Discretionary and Technology. Con-sumer stocks which disappointed included Lululemon Athletica and JCPenney. Tech-nology was hampered by an overweight in Apple and disappointing returns from IBM and Nuance Communications. In addition to the stellar returns of the fund’s biotechnology holdings, top contributors included Amazon, Google and Microsoft.

MID CAP FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Mid Cap Fund generally invests in common stocks of midsize companies and will, under normal market conditions, maintain at least 80% of its net assets in mid cap securities. The fund seeks attractive long-term returns through bottom-up security selection based on fundamental analysis in a diversified portfolio of high-quality growth companies with attractive valuations. These will typically be industry leading companies in niches with strong growth prospects. The fund’s portfolio managers believe in selecting stocks for the fund that show steady, sustainable growth and reasonable valuations. As a result, stocks of issuers that are believed to have a blend of both value and growth potential will be selected for investment.

PERFORMANCE DISCUSSION

The Ultra Series Mid Cap Fund (Class I) rose 29.28%, against the strong returns of the Russell Midcap® Index, which was up 34.76% during the twelve-month period. The fund was focused on high-quality companies with strong fundamentals, but lower quality, riskier assets performed better during the period. Most of the underperformance came from three sources. Holding cash in such a strong market is always a detriment, and over the year it amounted to some 40% of the fund’s performance gap against the Index. While holding some cash is generally part of prudent management of liquidity in a mutual fund, rapidly rising valuations during this period made it increasingly difficult for us to find attractive entry points for investing. In such circumstances we typically are patient, waiting for more opportune times to invest, and cash positions can rise. Most of the remaining lag came from the Heath Care and Industrial Sectors, as both sectors outperformed the overall market. Not holding the hottest biotech stocks made it hard to keep up in Heath Care, as the fund’s largest holding in the sector, Laboratory Corporation of America produced only single-digit gains. In the Industrials Sector the fund held some strong stocks, but results were hampered by holdings in C.H. Robinson and Ritchie Brothers Auctioneers. The fund had strong results in the year’s best performing sector, Consumer Discretionary where we had significant exposure to a number of index-beating stocks including Advance Auto Parts, advertiser Omnicom Group and retailers TJX and Tiffany.

SMALL CAP FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series Small Cap Fund invests primarily in a diversified mix of common stocks of small cap U.S. companies that are believed to be undervalued by various measures and offer sound prospects for capital appreciation. Under normal market conditions, the fund will maintain at least 80% of its net assets in small cap securities. The portfolio managers employ a value-oriented investment approach in selecting stocks, using proprietary fundamental research to identify securities of companies they believe have attractive valuations. The portfolio managers focus on companies with a record of above average rates of profitability that sell at a discount relative to the overall small cap market. Through fundamental research, the portfolio managers seek to identify those companies that possess one or more of the following characteristics: sustainable competitive advantages within a market niche; strong profitability and free cash flows; strong market share positions and trends; quality of and share ownership by management; and financial structures that are more conservative than the relevant industry average.

PERFORMANCE DISCUSSION

The Ultra Series Small Cap Fund (Class I) returned 32.77% for the 12-month period, underperforming the Russell 2000® Index, which advanced 38.82%. Sector allocation, which is a residual of the bottom-up stock selection process, was a detractor from relative results during the period, as our overweight exposure to the Materials and Utilities Sectors weighed on returns. A cash balance within the fund, which is necessary for fund operations but not a component of the fund’s benchmark index, was also a drag on performance in a rising market. On the positive side, an underweight allocation to the weak-performing Financials Sector and an overweight to the strong-performing Industrials Sector contributed to relative performance. Security selection also detracted from relative returns during the period as weak selection in the Consumer Discretionary, Industrials, and Health Care sectors was only partially offset by strong stock selection within Energy, Financials, and Utilities. The fund’s most significant detractors from

Ultra Series Fund | Management’s Discussion of Fund Performance  | December 31, 2013

relative performance during the period included real estate investment trust Campus Crest Communities, industrial products and systems producer ESCO Technologies, and designer and manufacturer of school and office products ACCO Brands. Independent energy company Halcon Resources was also among top detractors from absolute performance. The fund’s top contributors to relative returns during the period included provider of branded uniform and facility services programs, G&K Services, oil and natural gas exploration company, Diamondback Energy, and health care management services and solutions provider, CorVel. Positions in Belden, designer, manufacturer, and marketer of electronic cables and connectivity products for the specialty electronics and data-networking markets, and manufacturer, Albany International, were also among the largest contributors to absolute returns during the period.

INTERNATIONAL STOCK FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Ultra Series International Stock Fund will invest, under normal market conditions, at least 80% of its net assets in the stock of foreign companies. Typically, a majority of the fund’s assets are invested in relatively large cap stocks of companies located or operating in developed countries. The fund may also invest up to 30% of its assets in securities of companies whose principal business activities are located in emerging market countries. The portfolio managers typically maintain this segment of the fund’s portfolio in such stocks which it believes have a low market price relative to their perceived value based on fundamental analysis of the issuing company and its prospects. The fund may also invest in foreign debt and other income bearing securities at times when it believes that income bearing securities have greater capital appreciation potential than equity securities.

PERFORMANCE DISCUSSION

The Ultra Series International Equity Fund (Class I) returned 20.76% for the 12-month period, underperforming the MSCI EAFE (net) Index’s 22.78%. Exposure to emerging markets was a detriment, since developed markets were the leaders over the year. The fund also faced headwinds from a slight underweight in Japan, where the Nikkei Index rose 57%, buoyed by economic reforms from Prime Minister Abe and aggressive central bank stimulus. In the consumer discretionary sector, French auto parts supplier Valeo performed well on increased car sales. In financials, British insurer Prudential added to returns amid continued strong growth in its Asian unit. A below-benchmark weight and stock selection in the outperforming telecom services industry hurt the fund, as did the Energy Sector as French seismic surveyors CGG and Petroleum Geo-Services declined on disappointing results.

MADISON TARGET RETIREMENT 2020 FUND

INVESTMENT STRATEGY HIGHLIGHTS

The Madison Target Retirement 2020 Fund invests primarily in shares of registered investment companies according to an asset allocation strategy developed by the fund’s investment adviser for investors planning to retire in or within a few years of 2020. Over time, the fund’s asset allocation will gradually shift from the sector allocation shown below (see sector allocation in the grey box) until it reaches the more conservative allocation target of approximately 15-30% in stock funds and 70-85% in bond funds. The asset allocation strategy is designed to reduce the volatility of investment returns in the later years while still providing the potential for higher total returns over the target period.

PERFORMANCE DISCUSSION

The Ultra Series Madison Target Retirement 2020 Fund (Class I) returned 10.94% for the 12-month period, outperforming the Dow Jones Global Target 2020 Index return of 9.05%, while trailing the Morningstar Target Date 2016-2020 fund category average return of 11.57%. Our prejudice for capital preservation in this shorter-to-target fund was a detriment against more aggressive peers in the sort of rapidly ascending stock market we experienced in 2013. The two greatest positive contributors to performance were the fund’s relative overweight to U.S. stocks within the equity allocation, and a below-benchmark duration within the fixed income portion of the portfolio. The broad U.S. stock market (Russell 3000® Index) outperformed the international market (MSCI EAFE Index) by approximately 10% over the period. Bonds were hurt by a significant rise in interest rates since the end of 2012. The yield on the bellwether 10-year Treasury note began the year below 2% and climbed to just over 3% by year’s end. The fund‘s modest duration and floating rate holdings served to mitigate the losses within the fixed income portion of the fund. The two most negative detractors from performance were the fund’s underweighting to smaller cap stocks and the fund’s exposure to emerging markets debt. Emerging markets debt was dually impacted by the sharp rise in interest rates and a strengthening U.S. Dollar.

PERFORMANCE DISCUSSION

The Ultra Series Madison Target Retirement 2030 Fund (Class I) returned 16.56% for the 12-month period, almost identical to the Dow Jones Global Target 2030 Index return of 16.59%, and just behind the Morningstar Target Date 2026-2030 fund category average return of 16.65%. Our conservative positioning of asset allocation (59% equity compared to the Index’s 65%) was a relative detriment in 2013, with the rapid rise of the U.S. and overseas stock markets. On the other hand, the two greatest positive contributors to performance were the fund’s relative overweight to U.S. stocks within the equity allocation, and a below-benchmark duration within the fixed income portion of the portfolio. The broad U.S. stock market (Russell 3000® Index) outperformed the international market (MSCI EAFE Index) by approximately 10% over the period.

Notes to Management’s Discussion of Fund Performance

¹  Fund returns are calculated after fund level expenses have been subtracted, but do not include any separate account fees, charges or expenses imposed by the variable annuity and variable life insurance contracts that invest in the fund, as

described in the Prospectus. If these fees, charges, or expenses were included, fund returns would have been lower. Fund returns also assume that dividends and capital gains are reinvested in additional shares of the fund. Investment return and principal value will fluctuate, so an investor’s shares, when redeemed, may be worth more or less than when purchased. Further information relating to the fund’s performance is contained in the Prospectus and elsewhere in this report. The fund’s past performance is not indicative of future performance. Current performance may be lower or higher than the performance data cited. For Ultra Series Fund performance data current to the most recent month-end, please call 1-800-670-3600 or visit www.ultraseriesfund.com. Indices are unmanaged and investors cannot invest in them directly. Index returns do not reflect fees or expenses.

²  The management fee for the Conservative, Moderate, and Aggressive Allocation Funds was reduced from June 30, 2006-April 30, 2008. Effective October 1, 2009, Madison contractually agreed to waive a portion of the management fee of the Target Retirement Date 2020, 2030 and 2040 Funds from 0.40% to 0.20%. Effective February 17, 2011, the fee was permanently reduced to 0.20%. On September 1, 2011, shareholders of the Target Retirement Date Funds approved a new fee arrangement which includes an investment advisory fee of 0.25% annualized and a services agreement fee of 0.05% annualized. If the management fees had not been reduced, returns would have been lower.

1. ORGANIZATION

The Ultra Series Fund (the “Trust’’), a Massachusetts business trust, is registered under the Investment Company Act of 1940 (the “1940 Act’’), as amended, as a diversified, open-end management investment company. The Trust is a series fund with, at the end of the period covered by this report, 16 investment portfolios (individually, a “Fund,” and collectively, the “Funds’’), each with different investment objectives and policies. The Funds currently available at the end of the period were the Money Market Fund, Core Bond Fund (formerly Bond Fund), High Income Fund, Diversified Income Fund, Large Cap Value Fund, Large Cap Growth Fund, Mid Cap Fund, Small Cap Fund and International Stock Fund (collectively, the “Core Funds’’), the Conservative Allocation Fund, Moderate Allocation Fund and Aggressive Allocation Fund (collectively, the “Target Allocation Funds’’), and the Madison Target Retirement 2020 Fund, Madison Target Retirement 2030 Fund, Madison Target Retirement 2040 Fund, and Madison Target Retirement 2050 Fund, (collectively, the “Target Date Funds”).

The Declaration of Trust permits the Board of Trustees to issue an unlimited number of full and fractional shares of the Trust without par value. All Funds, except for the Target Date Funds, offer Class I and II shares. The Target Date Funds only offer a single class of shares, Class I shares. Each class of shares represents an interest in the assets of the respective Fund and has identical voting, dividend, liquidation and other rights, except that each class of shares bears its own distribution fees, if any, and its proportional share of Fund level expenses, and has exclusive voting rights on matters pertaining to Rule 12b-1 under the 1940 Act as it relates to that class and other class specific matters. Shares are offered to separate accounts (the “Accounts’’) of CMFG Life Insurance Company and to qualified pension and retirement plans of CMFG Life Insurance Company or its affiliates (“CUNA Mutual Group’’). The Trust may, in the future, offer other share classes to separate accounts of insurance companies and to qualified pension and retirement plans that are not affiliated with CUNA Mutual Group. The Trust does not offer shares directly to the general public.

The Trust has entered into a Management Agreement with Madison Asset Management, LLC. (the “Investment Adviser” or “Madison”). The Investment Adviser, in turn, has entered into subadvisory agreements with certain subadvisers (“Subadvisers”) for the management of the investments of the High Income, Small Cap and International Stock Funds.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements.

Portfolio Valuation: Securities and other investments are valued as follows: Equity securities, including American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and exchange-traded funds (“ETFs”) listed on any U.S. or foreign stock exchange or quoted on the National Association of Securities Dealers Automated Quotation System (“NASDAQ’’) are valued at the last quoted sale price or official closing price on that exchange or NASDAQ on the valuation day (provided that, for securities traded on NASDAQ, the Funds utilize the NASDAQ Official Closing Price). If no sale occurs, equities traded on a U.S. exchange, foreign exchange or on NASDAQ are valued at the bid price. Debt securities purchased with a remaining maturity of 61 days or more are valued on the basis of last available bid prices or current market quotations provided by dealers or pricing services approved by the Trust. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such for such investments. Municipal debt securities are traded via a network among dealers and brokers that connect buyers and sellers. Liquidity in the tax-exempt market has been reduced as a result of overall economic conditions and credit tightening. There may be little trading in the secondary market for the particular bonds and other debt securities, making them more difficult to value or sell. Asset-backed and mortgage-backed securities are valued by independent pricing services using models that consider estimated cash flows of each tranche of the security, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche.

Investments in shares of open-end mutual funds, including money market funds, are valued at their daily net asset value (“NAV”) which is calculated as of the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern Standard Time) on each day on which the New York Stock Exchange is open for business. NAV per share is determined by dividing each Fund’s total net assets by the number of shares of such Fund outstanding at the time of calculation. Because the assets of each Target Allocation and each Target Date Fund consist primarily of

135

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

shares of underlying funds, the NAV of each Fund is determined based on the NAV’s of the underlying funds. Total net assets are determined by adding the total current value of portfolio securities, cash, receivables, and other assets and subtracting liabilities. Short-term instruments having maturities of 60 days or less and all securities in the Money Market Fund are valued on an amortized cost basis, which approximates market value.

Over-the-counter securities not listed or traded on NASDAQ are valued at the last sale price on the valuation day. If no sale occurs on the valuation day, an over-the-counter security is valued at the last bid price. Exchange traded options are valued at the mean of the best bid and ask prices across all option exchanges. Financial futures contracts generally are valued at the settlement price established by the exchange(s) on which the contracts are primarily traded. The Trust’s Pricing Committee (the “Committee”) shall estimate the fair value of futures positions affected by the daily limit by using its valuation procedures for determining fair value, when necessary. Spot and forward foreign currency exchange contracts are valued based on quotations supplied by dealers in such contracts. Overnight repurchase agreements are valued at cost, and term repurchase agreements (i.e., those whose maturity exceeds seven days), swaps, caps, collars and floors, if any, are valued at the average of the closing bids obtained daily from at least one dealer.

Through the end of this reporting period, the value of all assets and liabilities expressed in foreign currencies was converted into U.S. dollar values using the then-current exchange rate at the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern Standard Time).

All other securities for which either quotations are not readily available, no other sales have occurred, or in the Investment Adviser’s opinion, do not reflect the current market value, are appraised at their fair values as determined in good faith by the Trust’s Pricing Committee (the “Committee’’) and under the general supervision of the Board of Trustees. When fair value pricing of securities is employed, the prices of securities used by the Funds to calculate NAV may differ from market quotations or official closing prices. Because the Target Allocation and Target Date Funds primarily invest in underlying funds, government securities and short-term paper, it is not anticipated that the Investment Adviser will need to “fair value” any of the investments of these Funds. However, an underlying fund may need to “fair value” one or more of its investments, which may, in turn, require a Target Allocation or

136

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

Target Date Fund to do the same because of delays in obtaining the underlying fund’s NAV.

A Fund’s investments (or underlying fund) will be valued at fair value if, in the judgment of the Committee, an event impacting the value of an investment occurred between the closing time of a security’s primary market or exchange (for example, a foreign exchange or market) and the time the Fund’s share price is calculated as of the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern Standard Time). Significant events may include, but are not limited to, the following: (1) significant fluctuations in domestic markets, foreign markets or foreign currencies; (2) occurrences not directly tied to the securities markets such as natural disasters, armed conflicts or significant government actions; and (3) major announcements affecting a single issuer or an entire market or market sector. In responding to a significant event, the Committee would determine the fair value of affected securities considering factors including, but not limited to: fundamental analytical data relating to the investment; the nature and duration of any restrictions on the disposition of the investment; and the forces influencing the market(s) in which the investment is purchased or sold. The Committee may engage an independent fair valuation service to adjust the valuations of foreign equity securities based on specific market-movement parameters established by the Committee and approved by the Trust.

Security Transactions and Investment Income: Security transactions are accounted for on a trade date basis. Net realized gains or losses on sales are determined by the identified cost method. Interest income is recorded on an accrual basis. Dividend income is recorded on ex-dividend date, except that certain dividends from foreign securities may be recorded after the ex-dividend date based on when the Fund is informed of the dividend. Amortization and accretion are recorded on the effective yield method.

Expenses: Expenses that are directly related to one Fund are charged directly to that Fund. Other operating expenses are prorated to the Funds on the basis of relative net assets. Class-specific expenses are borne by that class.

Classes: Income and realized and unrealized gains/losses are allocated to the respective classes on the basis of relative net assets. Repurchase Agreements: Each Fund may engage in repurchase agreements. In a repurchase agreement, a security is purchased for a relatively short period (usually not more than 7 days) subject to the

137

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

obligation to sell it back to the issuer at a fixed time and price plus accrued interest. The Funds will enter into repurchase agreements only with member banks of the Federal Reserve System and with “primary dealers’’ in U.S. Government securities. As of December 31, 2013, none of the Funds held open repurchase agreements.

The Trust has established a procedure providing that the securities serving as collateral for each repurchase agreement must be delivered to the Trust’s custodian either physically or in book-entry form and that the collateral must be marked to market daily to ensure that the repurchase agreement is fully collateralized at all times. In the event of bankruptcy or other default by a seller of a repurchase agreement, a Fund could experience one of the following: delays in liquidating the underlying securities during the period in which the Fund seeks to enforce its rights thereto, possible subnormal levels of income, declines in value of the underlying securities, or lack of access to income during this period and the expense of enforcing its rights.

Foreign Currency Transactions: The Trust’s books and records are maintained in U.S. dollars. Foreign currency denominated transactions (i.e., market value of investment securities, assets and liabilities, purchases and sales of investment securities, and income and expenses) are translated into U.S. dollars at the current rate of exchange. The Funds enter into contracts on the trade date to settle any securities transactions denominated in foreign currencies on behalf of the Funds at the spot rate at settlement.

Each Fund, except the Money Market Fund, which can only invest in U.S. dollar-denominated foreign money market securities, reports certain foreign currency-related transactions as components of realized gains or losses for financial reporting purposes, whereas such components are treated as ordinary income for federal income tax purposes. Only the International Stock Fund had net realized gains from foreign currency transactions, and that amount is included in the Statements of Operations under the heading “Net realized gain (loss) on investments” for that Fund.

The Funds do not isolate the portion of gains and losses on investments in securities that is due to changes in the foreign exchange rates from that which is due to changes in market prices of securities. Such amounts are categorized as gain or loss on investments for financial reporting purposes.

138

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

Forward Foreign Currency Exchange Contracts: Each Fund, except the Money Market Fund, may purchase and sell forward foreign currency exchange contracts for defensive or hedging purposes. When entering into forward foreign currency exchange contracts, the Funds agree to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. These contracts are valued daily. The Funds’ net assets reflect unrealized gains or losses on the contracts as measured by the difference between the forward foreign currency exchange rates at the dates of entry into the contracts and the forward rates at the reporting date. The Funds realize a gain or a loss at the time the forward foreign currency exchange contracts are settled or closed out with an offsetting contract. Realized and unrealized gains and losses are included in the Statements of Operations. As of December 31, 2013, none of the Funds had open forward foreign currency exchange contracts.

If a Fund enters into a forward foreign currency exchange contract to buy foreign currency for any purpose, the Fund will be required to place cash or other liquid assets in a segregated account with the Fund’s custodian in an amount equal to the value of the Fund’s total assets committed to the consummation of the forward contract. If the value of the securities in the segregated account declines, additional cash or securities will be placed in the segregated account so that the value of the account will equal the amount of the Fund’s commitment with respect to the contract.

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.

Illiquid Securities: Each Fund currently limits investments in illiquid securities to 15% of net assets at the time of purchase, except for Money Market which limits the investment in illiquid securities to 5% of net assets. An illiquid security is generally defined as any investment that may be difficult to sell within seven days for the price at which the Fund values it. At December 31, 2013, investments in securities of the Core Bond, High Income and Diversified Income Funds include issues that are illiquid. As of that date, the aggregate values of illiquid securities held by Core Bond, High Income and Diversified Income Funds were $10,901,951, $631,500, and $6,333,682, respectively, which represent 3.4%, 1.2% and 1.5% of net assets, respectively. Pursuant to guidelines adopted by the Board of Trustees, certain

139

unregistered securities are determined to be liquid and are not included within the percent limitations specified above. Information concerning the illiquid securities held at December 31, 2013, which includes cost and acquisition date, is as follows:

Delayed Delivery Securities: Each Fund may purchase securities on a when-issued or delayed delivery basis. “When-issued’’ refers to securities whose terms are available and for which a market exists, but that have not been issued. For when-issued or delayed delivery transactions, no payment is made until delivery date, which is typically longer than the normal course of settlement, and often a month or more after the purchase. When a Fund enters into an agreement to purchase securities on a when-issued or delayed delivery basis, the Fund segregates cash or other liquid securities, of any type or maturity, equal in value to the Fund’s commitment. Losses may arise due to changes in the market value of the underlying securities, if the counterparty does not perform under the contract, or if the issuer does not issue the securities due to political, economic or other factors. As of December 31, 2013, none of the Funds had entered into such transactions.

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.

Indemnifications: Under the Funds’ organizational documents, the Funds’ officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In the normal course of business, the Funds enter into contracts that contain a variety of representations and provide general indemnifications. The Funds’ maximum liability exposure under these arrangements is unknown, as future claims that have not yet occurred may be made against the Funds. However, based on experience, management expects the risk of loss to be remote.

Fair Value Measurements: Each Fund has adopted the FASB guidance on fair value measurements. Fair value is defined as the price that each Fund would receive upon

141

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

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 used in 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 – unadjusted 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 year ended December 31, 2013 maximized the use of observable inputs and minimized the use of unobservable inputs. The Funds utilized the following fair value techniques: multi-dimensional relational pricing model and option adjusted spread pricing; the Funds estimated the price that would have prevailed in a liquid market for an international equity security given information available at the time of evaluation. Through the year ended December 31, 2013, none of the Funds held securities

142

deemed as a Level 3 and there were no transfers between classification levels during the year.

The following is a summary of the inputs used as of December 31, 2013 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 category):

3. MANAGEMENT, SERVICES AND DISTRIBUTION AGREEMENTS

Management Agreement: For services under the Management Agreement, the Investment Adviser is entitled to receive a management fee, which is calculated daily and paid monthly, at an annual rate based upon the following percentages of average daily net assets:

Fund	Management Fee	Fund	Management Fee
Conservative Allocation	0.30%	Large Cap Growth	0.80%
Moderate Allocation	0.30%	Mid Cap	0.90%
Aggressive Allocation	0.30%	Small Cap	1.10%
Money Market	0.45%	International Stock*	1.15%
Core Bond	0.55%	Madison Target Retirement 2020	0.25%
High Income	0.75%	Madison Target Retirement 2030	0.25%
Diversified Income	0.70%	Madison Target Retirement 2040	0.25%
Large Cap Value	0.60%	Madison Target Retirement 2050	0.25%
*Effective December 31, 2013, the management fee for the International Stock Fund was reduced from 1.20% to 1.15%.

For all but the Target Date Funds, the Management Agreement requires the Investment Adviser to provide or arrange to provide overall management of the Funds, including but not limited to, investment advisory services, custody, transfer

145

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

agency, dividend disbursing, legal, accounting and administrative services. Neither Management Agreement includes Trustee compensation or the fees paid to the Trust’s independent Registered Public Accountant. For the Target Date Funds, the Management Agreement requires the Investment Adviser to provide investment management services to the Funds. Other services performed by the Investment Adviser for these Funds are covered under a separate Services Agreement (discussed below).

The Investment Adviser is solely responsible for the payment of all fees to the Subadvisers. The Subadvisers for the Funds are Shenkman Capital Management, Inc. for the High Income Fund, Wellington Management Company, LLP for the Small Cap Fund and effective December 31, 2013, NorthRoad Capital Management LLC, an affiliate of Madison, replaced Lazard Asset Management, LLC as the subadviser for the International Stock Fund. The Investment Adviser manages the Money Market Fund, Core Bond Fund, Diversified Income Fund, Large Cap Growth Fund, Large Cap Value Fund, Mid Cap Fund, Target Allocation Funds and the Target Date Funds.

The Investment Adviser may from time to time voluntarily agree to waive a portion of its fees or expenses related to the Funds. In that regard, the Investment Adviser waived a portion of management fees on the Money Market Class I Shares and Class II Shares. The amount of the daily waiver is equal to the amount required to maintain a minimum daily distribution rate of zero. For the year ended December 31, 2013, the waivers totaled $151,868 for Class I Shares and $5,527 for Class II Shares and are reflected as fees waived by the Investment Adviser in the accompanying Statements of Operations. The Investment Adviser does not have the right to recoup these waived fees.

Services Agreement: Effective September 1, 2011, the Investment Adviser entered into a services agreement (“Services Agreement”) for the Target Date Funds. Under the Services Agreement, Madison provides either directly or through outsourced arrangements all operational and support services of the Target Date Funds not provided under the Management Agreement discussed above. Under this Services Agreement, Madison receives a fee of 0.05% (annualized) of the average daily net assets of each Target Date Fund. In exchange for the aforementioned fee, Madison is responsible for paying all of the Funds’  fees and expenses, other than (i) the

146

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

management fee (described above), (ii) fees related to the Funds’ portfolio holdings (such as brokerage commissions, interest on loans, etc.), (iii) acquired Fund fees, and (iv) extraordinary or non-recurring fees (such as fees and costs relating to any temporary line of credit the Funds may maintain for emergency or extraordinary purposes). The direct expenses of the Funds’ independent trustees and independent auditors are paid out of this fee by the Target Date Funds. Pursuant to the Services Agreement, Madison has also agreed, until April 30, 2014, to waive and/or reimburse investment advisory fees and/or its services fee to the extent necessary to limit each Target Date Fund’s total operating expenses and underlying fees and expenses to 0.65% of average daily net assets. In applying this waiver, Madison must utilize good faith estimates of the fees and expenses of the underlying funds. For the year ended December 31, 2013, no fees were waived. The Investment Adviser does not have the right to recoup these waived fees, if any.

Distribution Agreement: MFD Distributor, LLC (“MFD”) serves as distributor of the Funds. The Trust adopted a distribution and service plan with respect to the Trust’s Class II shares pursuant to Rule 12b-1 under the 1940 Act. Under the plan, the Trust will pay a service fee with regard to Class II shares at an annual rate of 0.25% of each Fund’s daily net assets. MFD arranges to provide compensation to others that provide distribution and shareholder servicing services to the Funds and their shareholders. Fees incurred by the Funds under the plan are detailed in the Statements of Operations.

MFD may from time to time voluntarily agree to waive a portion of its fees or expenses related to the Funds. In this regard, the distributor waived all of the 12b-1 fees on the Money Market Class II shares for the purpose of maintaining a one-day yield of zero. For the year ended December 31, 2013, the waivers totaled $3,975 and are reflected as fees waived in the Statements of Operations. Neither MFD nor the Investment Adviser has the right to recoup these waived fees.

MFD changed its name from Mosaic Funds Distributor, LLC on February 1, 2013.

Other Expenses: Except as provided below, in addition to the management fee, the Trust is responsible for fees of the independent trustees, brokerage commissions and other expenses incurred in connection with the acquisition or disposition of investments, costs of borrowing money, expenses for independent audits, any potential taxes owed and extraordinary expenses as approved by a majority of independent trustees. Effective September 1, 2011, the fees for the independent

147

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

trustees and independent audits are paid out of the Services Agreement fee (noted above) for the Target Date Funds.

Certain officers and trustees of the Trust are also officers of the Investment Adviser. The Funds do not compensate their officers or affiliated trustees. Unaffiliated trustees receive from the Trust an attendance fee for each Committee meeting attended. The nominating and Governance Committee of the Board may change these fees at any time.

4. DIVIDENDS FROM NET INCOME AND DISTRIBUTIONS OF CAPITAL GAINS

The Money Market Fund declares dividends from net investment income and net realized gains from investment transactions, if any, daily, and net realized gains from investment transactions, if any, annually, which are reinvested in additional full and fractional shares of the Fund. The Funds declare dividends from net investment income and net realized gains from investment transactions, if any, annually, which are reinvested in additional full and fractional shares of the respective Funds.

Income and capital gain distributions, if any, are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Taxable distributions from income and realized capital gains of the Funds may differ from book amounts earned during the period due to differences in the timing of capital gains recognition, and due to the reclassification of certain gains or losses from capital to income.

5. SECURITIES TRANSACTIONS

For the year ended December 31, 2013, aggregate cost of purchases and proceeds from sales of securities, other than short-term investments, were as follows:

6. FOREIGN SECURITIES

Each Fund may invest in foreign securities; however, the Money Market Fund is limited to U.S. dollar-denominated foreign money market securities. Foreign securities include American Depositary Receipts (“ADRs’’), European Depositary Receipts (“EDRs’’), Global Depositary Receipts (“GDRs’’), Swedish Depositary Receipts (“SDRs’’) and foreign money market securities. U.S. dollar-denominated securities that are part of the Merrill Lynch U.S.Domestic Master Index are not considered a foreign security.

Certain Funds have reclaim receivable balances, in which the Funds are due a reclaim on the taxes that have been paid to some foreign jurisdictions. The values of all reclaims are not significant for any of the Funds and are reflected in Other Assets on the Statements of Assets and Liabilities. These receivables are reviewed to ensure the current receivable balance is reflective of the amount deemed to be collectable.

7. SECURITIES LENDING

149

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

Each Fund, except the Target Allocation, Money Market, Small Cap and Target Retirement Funds, entered into a Securities Lending Agreement (the “Agreement”) with State Street Bank and Trust Company (“State Street”). Under the terms of the Agreement, the Funds may lend portfolio securities to qualified borrowers in order to earn additional income. The Agreement requires that loans are collateralized at all times by cash or other liquid assets at least equal to 102% of the value of the securities, which is determined on a daily basis. Amounts earned as interest on investments of cash collateral, net of rebates and fees, if any, are included in the Statements of Operations. The primary risk associated with securities lending is if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Funds could experience delays and costs in recovering securities loaned or in gaining access to the collateral.

At December 31, 2013, none of the Funds had securities out on loan.

8. FEDERAL INCOME TAX INFORMATION

It is each Fund’s policy to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 applicable to regulated investment companies and to distribute all its taxable income to its shareholders. Accordingly, no provisions for federal income taxes are recorded in the accompanying statements.

The Funds have not recorded any liabilities for material unrecognized tax benefits as of December 31, 2013. It is each Fund’s policy to recognize accrued interest and penalties related to uncertain tax benefits in income taxes, as appropriate. Tax years that remain open to examination by major tax jurisdictions include tax years ended December 31, 2010 through December 31, 2013.

The tax character of distributions paid during the years ended December 31, 2013 and 2012 was as follows:

At December 31, 2013, the aggregate gross unrealized appreciation/depreciation and net unrealized appreciation for all securities as computed on a federal income tax basis for each Fund were as follows:

Madison Target Retirement 2050	2,283,992		21,359		2,262,633

The differences between the book unrealized amounts reflected in the Statement of Assets and Liabilities and tax unrealized amounts (shown above) are due to the tax deferral of losses on wash sales.

Reclassification Adjustments: Paid-in capital, undistributed net investment income, and accumulated net realized gain (loss) have been adjusted in the Statements of Assets and Liabilities for permanent book-tax differences for all funds.

Differences primarily relate to the tax treatment of net operating losses, paydown gains and losses, foreign currency gains and losses, and distributions from real estate investment trusts and passive foreign investment companies.

To the extent these book and tax differences are permanent in nature, such amounts are reclassified at the end of the fiscal year among paid-in capital in excess of par value, undistributed net investment income (loss) and undistributed net realized gain

9. INVESTMENT RISKS

Investing in certain financial instruments, including forward foreign currency contracts, involves certain risks. Risks associated with these instruments include potential for an illiquid secondary market for the instruments or inability of counterparties to perform under the terms of the contracts, changes in the value of foreign currency relative to the U.S. dollar and financial statement volatility resulting from an imperfect correlation between the movements in the prices of the instruments and the prices of the underlying securities and interest rates being

155

Ultra Series Fund | December 31, 2013

Notes to Financial Statements

hedged. The International Stock Fund may enter into these contracts primarily to protect these Funds from adverse currency movements.

Investing in foreign securities involves certain risks not necessarily found in U.S. markets. These include, but are not limited to, risks associated with adverse changes in economic, political, regulatory and other conditions, changes in currency exchange rates, exchange control regulations, expropriation of assets or nationalization, imposition of withholding taxes on dividend or interest payments or capital gains, and possible difficulty in obtaining and enforcing judgments against foreign entities. Further, issuers of foreign securities are subject to different, and often less comprehensive, accounting, reporting and disclosure requirements than domestic issuers.

The High Income Fund invests in securities offering high current income which generally will include bonds in the below investment grade categories of recognized ratings agencies (so-called “junk bonds’’). These securities generally involve more credit risk than securities in the higher rating categories. In addition, the trading market for high yield securities may be relatively less liquid than the market for higher-rated securities. The High Income Fund generally invests at least 80% of its net assets in high yield securities.

The Target Allocation Funds and Target Date Funds are fund of funds, meaning that they invest primarily in the shares of other registered investment companies (the “underlying funds’’), including exchange traded funds (“ETFs”). Thus, each Fund’s investment performance and its ability to achieve its investment goal are directly related to the performance of the underlying funds in which it invests; and the underlying fund’s performance, in turn, depends on the particular securities in which that underlying fund invests and the expenses of that fund. Accordingly, these Funds are subject to the risks of the underlying funds in direct proportion to the allocation of their respective assets among the underlying funds.

Additionally, the Target Allocation Funds and Target Date Funds are subject to asset allocation risk and manager risk. Manager risk (i.e., fund selection risk) is the risk that the fund(s) selected to fulfill a particular asset class underperforms its peers. Asset allocation risk is the risk that the allocation of the Fund’s assets among the various asset classes and market segments will cause the Fund to underperform other funds with a similar investment objective.

The Mid Cap Fund received proceeds of approximately $1,574,400 from the sale of its LYO equity securities in December 2007. The Trust has not been named as a defendant in this litigation as of the date of this report.

All Other Matters

Other than what is noted above, management has evaluated the impact of all other subsequent events on the Funds through the date the financial statements were available for issue.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of Ultra Series Fund:

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Ultra Series Fund, comprising the Conservative Allocation Fund, Moderate Allocation Fund, Aggressive Allocation Fund, Money Market Fund, Core Bond Fund (formerly Bond Fund), High Income Fund, Diversified Income Fund, Large Cap Value Fund, Large Cap Growth Fund, Mid Cap Fund, Small Cap Fund, International Stock Fund, Madison Target Retirement 2020 Fund, Madison Target Retirement 2030 Fund, Madison Target Retirement 2040 Fund, and Madison Target Retirement 2050 Fund (collectively, the “Funds”) as of December 31, 2013, and the related statements of operations for the year then ended, and the statements of changes in net assets and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Funds’ 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 Funds are not required to have, nor were we engaged to perform, an audit of their 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 Funds’ 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, 2013, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 as of December 31, 2013, the results of their operations for the year then ended, and the

160

BOARD APPROVAL OF ADVISORY AND SUBADVISORY CONTRACTS

The Board of Trustees reviewed a variety of matters in connection with the Trust’s investment advisory contract with the Investment Adviser and the subadvisory contracts with the applicable Subadvisers at an in-person meeting of the Board held in July 2013. The following summarizes the Board’s process and considerations during that meeting.

With regard to the nature, extent and quality of the services to be provided by the Investment Adviser and each Subadviser, the Board reviewed the biographies and tenure of the personnel involved in Trust management and the experience of the Investment Adviser (and applicable Subadviser) 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 Investment Adviser and each Subadviser discussed their firms’ ongoing investment philosophies and strategies intended to provide performance consistent with each Fund’s investment objectives under various market scenarios. The Trustees also noted their familiarity with the Investment Adviser and its affiliates due to the Investment 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 Investment Adviser. Such services included arranging for third party service providers to provide all necessary administration as well as supervising any Subadvisers to Fund portfolios.

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. They reviewed both long-term and short-term performance and considered the effect on long-term performance that may have been attributable to any previous investment advisers to any Fund. They also considered whether any relative underperformance was appropriate in view of the Investment Adviser’s conservative investment philosophy. The Board performed this review in connection with the Investment Adviser and each Subadviser that manages a subadvised Fund portfolio. In connection with the review of performance, the Board engaged in a

162

Ultra Series Fund | December 31, 2013

Other Information (unaudited)

comprehensive discussion of market conditions and discussed the reasons for Fund performance under such conditions. With regard to fixed-income Funds, the Board considered the relatively conservative investment philosophy followed by the Funds during a period of historically low interest rates and the relative risks to fixed-income Funds in the current environment. Representatives of the Investment Adviser and each Subadviser 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 Trusts, the Board reviewed the expense ratios for a variety of other funds in each Fund portfolio’s peer group with similar investment objectives. Again, the Board reviewed these matters in connection with the Investment Adviser and each Subadviser that manages a subadvised Fund portfolio.

The Board noted that the Investment Adviser or its affiliates, and, as applicable, each Subadviser, provided investment management services to other investment company and/or non-investment company clients and considered the fees charged by the Investment Adviser (and respective Subadviser) 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 Investment Adviser (or Subadviser, if applicable) 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 Investment Adviser (or Subadviser, if applicable) 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 Investment Adviser (or Subadviser, if applicable) 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

163

Ultra Series Fund | December 31, 2013

communication services required to be handled by the Investment Adviser (or Subadviser, if applicable) which are performed for investment company clients but are not performed for other institutional clients.

TThe 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 Trust: (1) an advisory fee and a capped administrative “services” expense for its Target Retirement Date Funds; and (2) for the remaining series, a unitary fee with limited independent expenses for Trustee compensation and audit fees not covered by the unitary fee. The Board reviewed 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 Trusts were appropriate. The Board reviewed materials demonstrating that although the Investment Adviser is compensated for a variety of the administrative services it provides or arranges to provide to the Target Retirement Date Funds of the Trust pursuant to its administrative services agreements with those series, 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, in the case of the Target Retirement Date series, or in excess of the unitary fee, in the case of the remaining series of the Trust, are paid by the Investment Adviser from the investment advisory fees earned. In this regard, the Trustees noted that examination of each Fund 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.

The Board recognized that to the extent a Fund portfolio invests in other mutual funds also managed by the Investment Adviser (or its affiliates), the Investment Adviser (or an affiliate) receives investment advisory fees from both the Fund portfolio and the underlying mutual fund. The Board was satisfied in this regard that the Investment Adviser (or an affiliate) provides separate services to each “Fund of funds” portfolios and the underlying mutual funds in which each such Fund invests in exchange for the fees received from them.

In reviewing costs and profits, the Board noted that for some smaller Fund portfolios, the salaries of all portfolio management personnel, trading desk personnel, corporate

164

Ultra Series Fund | December 31, 2013

Other Information (unaudited)

accounting personnel and employees of the Investment 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 is profitable to the Investment 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 Investment Adviser including the Trust as a consolidated Fund family. The Trustees noted that total assets managed by the Investment Adviser and its affiliates were in excess of $15 billion at the time of the meeting. As a result, although the fees paid by each Fund portfolio at its present size might not be sufficient to profitably support a stand-alone fund, the Trust is reasonably profitable to the Investment Adviser as part of its larger, diversified organization. In sum, the Trustees recognized that the Trust is important to the Investment Adviser and is managed with the attention given to the Investment Adviser’s other clients.

With regard to the extent to which economies of scale would be realized as each Fund 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. In addition, the Trustees recognized that the Investment Adviser was currently waiving fees with with regard to the Money Market Fund.

Counsel to the Trust’s Independent Trustees confirmed that the Trust’s Independent Trustees met previously and reviewed the written contract renewal materials provided by the Investment Adviser. He 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 more 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 Investment Adviser and the Subadvisers and representatives of the Investment Adviser and Subadvisers, respectively, discussed each matter raised.

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 (including applicable subadvisory fees) are fair and reasonable for each respective Fund portfolio and that renewal of

165

its respective Advisory, Subadvisory and Services Agreements are in the best interests of each respective Fund portfolio and its shareholders.

In the course of their review of the contract renewal materials, the Board also reviewed and discussed with counsel the “Rule 12b-1” plans adopted by some of the Funds. Representatives of the Investment Adviser directed the Board to the written materials regarding these matters during the course of the Board’s consideration of the Rule 12b-1 plans. 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.

FUND EXPENSES PAID BY SHAREHOLDERS

As a shareholder of the Funds, you pay no transaction costs, but do incur ongoing costs which include management fees; disinterested trustee fees; brokerage commissions and other expenses incurred in connection with the acquisition or disposition of investments; costs of borrowing money; expenses for independent audits, taxes, and extraordinary expenses as approved by a majority of the disinterested trustees. The examples in the table that follows are 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.

The examples below are based on an investment of $1,000 invested for the six-month period ended December 31, 2013. Expenses paid during the period in the table below are equal to each Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half fiscal year period).

Actual Expenses

The table below provides information about actual account values using actual expenses and actual returns for the Funds. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table for the Fund you own under the heading entitled “Actual” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the Funds’ actual expense ratios and an assumed rate of return of 5% per year before expenses, which are not the Funds’ actual returns. 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 this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare the 5% hypothetical example of the Funds you own with the 5% hypothetical examples that appear in the shareholder reports of other similar funds.

OTHER CONSIDERATIONS

While investments in securities have been keystones in wealth building and management, at times these investments have produced surprises. Those who enjoyed growth and income of their investments generally were rewarded for the risks they took by investing in the markets. Although the Investment Adviser seeks to appropriately address and manage the risks identified and disclosed to you in connection with the management of the securities in the Funds, you should understand that the very nature of the securities markets includes the possibility that there may be additional risks of which we are not aware. We certainly seek to identify all applicable risks and then appropriately address the, take appropriate action to reasonably manage them and, of course, to make you aware of them so you can determine if they exceed your risk tolerance. Nevertheless, the often volatile

169

Ultra Series Fund | December 31, 2013

Other Information (unaudited)

nature of the securities markets and the global economy in which we work suggests that the risk of the unknown is something to consider in connection with an investment in securities. Unforeseen events could under certain circumstances produce a material loss of the value of some or all of the securities we manage for you in the Funds.

One of our most important responsibilities as investment company managers is to communicate with shareholders in an open and direct manner. Some of our comments in our letters to shareholders are based on current management expectations and are considered “forward-looking statements.” Actual future results, however, may prove to be different from our expectations. You can identify forward-looking statements by words such as “estimate,” ”may,” ”will,” ”expect,””believe,” ”plan” and other similar terms. We cannot promise future returns. Our opinions are a reflection of our best judgment at the time this report is compiled, and we disclaim any obligation to update or after forward-looking statements as a result of new information, future events, or otherwise.

EX-99.CODE ETH

Madison Funds

Ultra Series Fund

Madison Mosaic Funds (through April 19, 2013)

Madison Strategic Sector Premium Fund

Madison Covered Call & Equity Strategy Fund (effective January 1, 2013)

Code of Ethics for Principal Executive and Senior Financial Officers

The following code of ethics is designed to address the disclosure requirements of Item 2 of Form N‑CSR,¹ which implements Section 406 of the Sarbanes-Oxley Act of 2002 concerning disclosure of a code of ethics for principal executive and senior financial officers.

I.    Covered Officers/Purpose of the Code

This code of ethics (this “Code”) for the investment companies within the complex (collectively, “Funds” and each “the Company” or “a Company”) applies to the Company’s Principal Executive Officer and Principal Financial Officer (the “Covered Officers” each of whom are set forth in Exhibit A) for the purpose of promoting:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• full, fair, accurate, timely and understandable disclosure in reports and documents that a registrant files with, or submits to, the Securities and Exchange Commission (“SEC”) and in other public communications made by the Company;

• compliance with applicable laws and governmental rules and regulations;

• the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

• accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

_________________________

¹Item 2 of Form N-CSR requires a registered management investment company to disclose annually whether, as of the end of the period covered by the report, it has adopted a code of ethics that applies to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons

performing similar functions, regardless of whether these officers are employed by the registrant or a third party. If the registrant has not adopted such a code of ethics, it must explain why it has not done so. The registrant must also: (1) file with the SEC a copy of the code as an exhibit to its annual report; (2) post the text of the code on its Internet website and disclose, in its most recent report on Form N-CSR, its Internet address and the fact that it has posted the code on its Internet website; or (3) undertake in its most recent report on Form N-CSR to provide to any person without charge, upon request, a copy of the code and explain the manner in which such request may be made. Disclosure is also required of amendments to, or waivers (including implicit waivers) from, a provision of the code in the registrant’s annual report on Form N-CSR or on its website. If the registrant intends to satisfy the requirement to disclose amendments and waivers by posting such information on its website, it will be required to disclose its Internet address and this intention.

II.    Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his service to, the Company. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Company.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Company and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (“Investment Company Act”) and the Investment Advisers Act of 1940 (“Investment Advisers Act”). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Company because of their status as “affiliated persons” of the Company. The Company's and the investment adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Company and the investment adviser of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Company or for the adviser, or for both), be involved in establishing policies and implementing decisions that will have different effects on the adviser and the Company. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Company and the adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Company. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Funds’ Boards of Directors (“Boards”) that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the

personal interest of a Covered Officer should not be placed improperly before the interest of the Company.

*        *        *        *    

Each Covered Officer must:

• not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Company whereby the Covered Officer would benefit personally to the detriment of the Company;

• not cause the Company to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit the Company;

• not use material non-public knowledge of portfolio transactions made or contemplated for the Company to trade personally or cause others to trade personally in contemplation of the market effect of such transactions (recognizing that such matters are addressed in the Company’s and the Company’s investment manager’s general Code of Ethics and Rules to Prevent Insider Trading); and

• not retaliate against any other Covered Officer or any employee of the Funds or their affiliated persons for reports of potential violations that are made in good faith.

There are some conflict of interest situations that should always be discussed with the General Counsel or other senior officer of the Company not otherwise covered by this Code if material. Examples of these include:² 

• service as a director on the board of any public or private company;

• the receipt of any gifts provided the value of such gifts do not exceed $100 per person per year, but not including the occasional meal, ticket to a sporting event or theater, or comparable entertainment from any company with which the Company or its affiliates has current or prospective business dealings unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

• any ownership interest in, or any consulting or employment relationship with, any of the Company’s service providers, other than its investment adviser, principal underwriter, administrator or any affiliated person thereof;

• a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Company for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer’s employment, such as compensation or equity ownership.

III.    Disclosure and Compliance

• Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Company;

• each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Company to others, whether within or outside the Company, including to the Company’s directors and auditors, and to governmental regulators and self-regulatory organizations;

• each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Funds and the adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made by the Funds; and

• it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV.    Reporting and Accountability

Each Covered Officer must:

• upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Board, or orally confirm such receipt in person before the Board (as reflected in the Company’s minutes) that he has received, read, and understands the Code;

• annually thereafter affirm to the Board that he has complied with the requirements of the Code; and

• notify the General Counselpromptly if he knows of any violation of this Code. Failure to do so is itself a violation of this Code. The General Counsel shall report any such violations to the Audit Committee of the Company.

____________________________

²Any activity or relationship that would present a conflict for a Covered Officer would likely also present a conflict for the Covered Officer if a member of the Covered Officer’s family engages in such an activity or has such a relationship.

The General Counsel is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation.³ However, any approvals or waivers⁴ sought by the any of the officers covered by this Code will be considered by the Audit Committee (the “Committee”).

The Funds will follow these procedures in investigating and enforcing this Code:

• the General Counsel will take all appropriate action to investigate any potential violations reported to him;

• if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

• any matter that the General Counsel believes is a violation will be reported to the Committee;

• if the Committee concurs that a violation has occurred, it will inform and make a recommendation to the Board, which will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to end the Covered Officer’s association with the Funds;

• the Committee will be responsible for granting waivers, as appropriate; and

• any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.    Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds, the Funds’ adviser, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Funds’ and their investment adviser’s and principal underwriter’s codes of ethics under Rule 17j-1 under the Investment Company Act and the adviser’s more detailed policies and procedures set forth in the Madison Investment Advisors/Madison Scottsdale, LC/Madison Funds/Ultra Series Fund/Madison Mosaic Funds/Madison Strategic Sector Premium Fund et. al. Compliance and Procedures Manual, including the Code of Ethics applicable to all employees and Policies and

Procedures to Prevent Insider Trading, are separate requirements applying to the Covered Officers and others, and are not part of this Code.    

VI.    Amendments

Any amendments to this Code, other than amendments to Exhibit A, must be approved or ratified by a majority vote of the Board, including a majority of independent trustees.

_______________________________

³The General Counsel is authorized to consult, as appropriate, with the Audit Committee, counsel to the Company and/or counsel to the Independent Trustees, and is encouraged to do so.

⁴Item 2 of Form N-CSR defines “waiver” as “the approval by the registrant of a material departure from a provision of the code of ethics” and “implicit waiver,” which must also be disclosed, as “the registrant’s failure to take action within a reasonable period of time regarding a material departure from a provision of the code of ethics that has been made known to an executive officer” of the registrant.

VII.    Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the appropriate Company, its adviser and the Committee.

VIII.    Internal Use

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Company, as to any fact, circumstance, or legal conclusion.

Adopted by the Mosaic Board on July 23, 2003 and the Madison Strategic Sector Premium Fund Board on March 2, 2005 and the Madison Funds (formerly known as MEMBERS Mutual Funds) and Ultra Series Fund Boards on August 27, 2009 to be effective July 1, 2009 and the Madison Covered Call & Equity Strategy Fund Board on December 21, 2012 to be effective January 1, 2013.
