Curian Series Trust (Unaudited)

April 30, 2012

Dear Fellow Investor,

Enclosed is the semiannual report for the Curian Series Trust for the period ended April 30, 2012.

The extreme volatility that the U.S. equity markets experienced during the third quarter of 2011 moderated significantly during the last two months of 2011 and first four months of 2012.  During that period, the Chicago Board Options Exchange Volatility Index (“VIX”) fell 52.40%, from 36.03 to 17.15, as equity markets rallied in response to signs of strength in the economy.

Although the Standard & Poor’s 500® Index (“S&P 500”) began and ended the six-month period with a monthly loss, over the timeframe, the Index returned 11.74% and delivered its biggest first-quarter rally since 1998.  The Dow Jones Industrial Average Index (“DJIA”) and NASDAQ Composite Index (“NASDAQ”) also performed strongly, returning 10.56% and 16.84%, respectively, over the six-month period.  Through April 30, 2012, the S&P 500 posted a calendar year-to-date gain of 11.05%, while the DJIA returned 8.12% and the NASDAQ gained 14.64%.  World equity markets also posted gains over the six months from November 1, 2011, through April 30, 2012, although they underperformed U.S. markets.  The MSCI World Index, the MSCI EAFE Index and the MSCI Emerging Markets Index rose 6.60%, 1.38% and 3.68%, respectively.

In contrast to surging equity markets, U.S. Treasuries performed poorly during the first quarter of 2012, posting a loss of 1.29%, according to the Barclays Capital U.S. Treasury Index.  However, renewed fears over the European debt crisis, along with concerns about a weakening U.S. economy, pushed the Index up 1.38% during April 2012, and it posted a year-to-date gain through April 30 of 0.07%.  Corporate bonds were stronger performers than U.S. Treasuries during the first four months of 2012.  According to Bank of America Merrill Lynch Index data, U.S. investment grade corporate bonds returned an average of 2.44% during the first quarter of 2012 and an additional 0.8% during the month of April, while high-yield bonds rose 5.15% during the first quarter and 0.7% during April.

Economic growth in the U.S. surged during the fourth quarter of 2011.  The nation’s gross domestic product (“GDP”) expanded at an annualized rate of 3.0%, the highest rate of growth since the second quarter of 2010.  However, the U.S. Department of Commerce reported in April that GDP growth slowed to 2.2% during the first quarter of 2012.

While unemployment remained high during the six-month period from November 2011 through April 2012, the unemployment rate improved each month, falling from 8.7% in November to 8.1% in April—the lowest level since January 2009.  The rate declined in April because more Americans left the workforce, rather than from improved hiring trends.  April 2012 marked the third straight month that U.S. employers cut back on hiring, adding just 115,000 workers to their payrolls.

Throughout the period from November 2011 through April 2012, the U.S. Federal Reserve (the “Fed”) continued to replace shorter-term assets in its holdings with longer-term debt in an attempt to lower borrowing costs.  This economic stimulus program, called “Operation Twist,” is expected to conclude in June.  However, in March 2012, Fed Chairman Ben Bernanke said the central bank would consider further stimulus.  Additionally, in January 2012, the Fed pledged to keep the Fed funds rate target at the historically low range of 0.00% to 0.25% until late 2014.

Curian Capital, LLC (“Curian”) is dedicated to providing financial professionals and their clients with the most effective investment solutions possible to meet their financial goals.  Therefore, in November 2011, Curian launched the Curian Series Trust Funds, which give clients access to the expertise of investment management firms including Pacific Investment Management Company, LLC (“PIMCO”) and Wellington Management Company, LLP (“Wellington Management”).  Curian’s ongoing commitment to platform enhancements provides investors with a broader range of asset management solutions.

At Curian, we provide you with a state-of-the-art investment platform that offers you and your financial professional 24/7 access to choose the investment options necessary to achieve your financial goals.  Thank you for choosing Curian for your investment needs.

(1)Notional amount is stated in USD unless otherwise noted.

(2)If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay the buyer of protection an amount equal to the notional amount of the referenced obligation and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap agreement less the recovery value of the reference obligation or underlying securities comprising the referenced index.

(3)Implied credit spreads, represented in absolute terms, utilized in determining the value of credit default swap agreements on corporate issues, sovereign issues of an emerging market country and credit indices serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative.  The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement.  Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(4)The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs is limited to the total notional amount which is defined under the terms of each swap agreement.

(5)If the Fund is a buyer of protection, the Fund pays the fixed rate.  If the Fund is a seller of protection, the Fund receives the fixed rate.

(1)Notional amount is stated in USD unless otherwise noted.

(2)If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the referenced obligation agreement and deliver the referenced obligation or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap agreement less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(3)If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay the buyer of protection an amount equal to the notional amount of the referenced obligation and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap agreement less the recovery value of the reference obligation or underlying securities comprising the referenced index.

(4)Implied credit spreads, represented in absolute terms, utilized in determining the value of credit default swap agreements on corporate issues, sovereign issues of an emerging market country and credit indices serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative.  The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement.  Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5)The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs is limited to the total notional amount which is defined under the terms of each swap agreement.

(6)If the Fund is a buyer of protection, the Fund pays the fixed rate.  If the Fund is a seller of protection, the Fund receives the fixed rate.

Notes to Financial Statements

April 30, 2012

NOTE 1.  ORGANIZATION

The Curian Series Trust (“Trust”) is an open-end management investment company organized under the laws of the state of Massachusetts, by a Declaration of Trust, dated November 5, 2010.  The Trust is registered with the U.S. Securities and Exchange Commission (“SEC”) under the Investment Company Act of 1940, as amended, (“1940 Act”), and its shares are registered under the Securities Act of 1933 (“1933 Act”), as amended.  The Trust currently offers shares in three (3) separate funds (each a “Fund”, and collectively, “Funds”), each with its own investment objective:  Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund, for which Pacific Investment Management Company LLC (“PIMCO”) serves as the Sub-Adviser, and Curian/WMC International Equity Fund, for which Wellington Management Company, LLP (“WMC”) serves as the Sub-Adviser.  PIMCO and WMC are referred to herein as a “Sub-Adviser”.  The Funds are diversified Funds for purposes of the 1940 Act.

Curian Capital, LLC (“Curian”, the “Adviser” or the “Administrator”) serves as the investment adviser and administrator of the Funds with the responsibility for the professional investment supervision and management of the Funds.  Curian is a wholly owned subsidiary of Jackson National Life Insurance Company (“Jackson”), which is in turn wholly owned by Prudential plc, a publicly traded company incorporated in the United Kingdom.  Prudential plc is not affiliated in any manner with Prudential Financial Inc., a company whose principal place of business is in the United States of America.  At October 31, 2011, Curian owned 100% of the outstanding shares of beneficial interest in each of the Funds.  The Funds commenced operations on November 3, 2011.  At April 30, 2012, Curian owned the following shares of each Fund:

	Shares
Curian/PIMCO Income Fund	4,000
Curian/PIMCO Total Return Fund	4,000
Curian/WMC International Equity Fund	4,000

Purchases and redemptions of shares of the Funds are initiated by Curian and shares may be purchased on behalf of clients in Curian’s managed account program.  Each Fund offers one share class without a sales charge.

NOTE 2.  SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”):

Security Valuation - Curian has entered into a Sub-Administration and Fund Accounting Services Agreement on behalf of the Funds with Jackson Fund Services (“JFS” or the “Sub-Administrator”), a division of Jackson National Asset Management, LLC (“JNAM”).  JNAM is a subsidiary of Jackson and an affiliate of Curian.  Under the Trust’s valuation policy and procedures, the Trust’s Board of Trustees (“Board”) has delegated the daily operational oversight of the securities valuation function to the Pricing Committee of JFS (“Pricing Committee”) which consists of certain officers of the Trust and JNAM management.  The Pricing Committee is responsible for determining fair valuations for any security for which market quotations are not readily available.  For those securities fair valued under procedures adopted by the Board, the Pricing Committee reviews and affirms the reasonableness of the fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.  The Pricing Committee’s fair valuation determinations are subject to review by the Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

The net asset value (“NAV”) of each Fund shall be determined as of the close of trading (generally, 4:00 PM Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open for trading.  Stocks traded on an exchange are generally valued at the official closing price of the exchange where the security is principally traded.  If there is no official closing price for the security, the security may be valued at the last quoted sale price on the exchange where the security is principally traded or final bid price in the absence of a sale.  Stocks not listed on a national or foreign stock exchange may be valued at the closing bid price on the over-the-counter market.  Investments in mutual funds are valued at the NAV per share determined as of the close of the NYSE on each valuation date.  Short-term securities maturing within sixty (60) days are valued at amortized cost, unless it is determined that such practice does not approximate market value.  Debt securities are generally valued by independent pricing services approved pursuant to procedures approved by the Board.  If pricing services are unable to provide valuations, debt securities are valued at the most recent bid quotation or evaluated price, as applicable, obtained from the Sub-Adviser, a broker/dealer or widely used quotation system.  Futures contracts traded on a liquid exchange are valued at the settlement price.  If the settlement price is not available, exchange traded futures are valued at the last sales price as of the close of business on the local exchange.  Forward foreign currency contracts are generally valued at the foreign currency exchange rate as of the close of the NYSE.  Centrally cleared swap agreements are valued by the exchange via pricing models using observable inputs.  Over the counter (“OTC”) derivatives, such as options and swap agreements, are generally valued by approved pricing services.  If the pricing services are unable to provide valuations, OTC derivatives are valued at the most recent bid quotation or evaluated price, as applicable, obtained from a broker/dealer or by pricing models using observable inputs.  Pricing services utilized to value debt and derivatives securities may use various pricing techniques which take into account appropriate factors such as:  yield; credit quality; coupon rate; maturity; type of issue; trading characteristics; call features; credit ratings; broker quotes; and other relevant data.

Market quotations may not be readily available for certain investments or it may be determined that a quotation for an investment does not represent market value.  In such instances, the investment is valued as determined in good faith using procedures adopted by the Board.  Situations that may require an investment to be fair valued may include instances where a security is thinly traded, halted or restricted as to resale.  In addition, investments may be fair valued based on the occurrence of a significant event.  Significant events may be specific to a particular issuer, such as mergers, restructurings or defaults.  Alternatively, significant events may affect an entire market, such as natural disasters, government actions and significant changes in value of U.S. securities markets.  Securities are fair valued based on observable and unobservable inputs, including the Sub-Administrator’s or Pricing Committee’s own assumptions in determining fair value of an investment.  Under the procedures adopted by the Board, the Sub-Administrator may

Curian Series Trust (Unaudited)

Notes to Financial Statements

April 30, 2012

rely on pricing services or other sources, including the Funds’ Adviser and Sub-Advisers, to assist in determining the fair value of an investment.  Factors considered to determine fair value may include the correlation with price movement of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer and trading or other market data.  The Funds have retained an independent statistical fair value pricing service to assist in the fair valuation process for securities traded in foreign markets in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which the NAVs are determined.

If an investment is valued at a fair value for purposes of calculating a Fund’s NAV, the value may be different from the last quoted price for the investment depending on the source and method used to determine the value.  Although there can be no assurance, in general, the fair value of the investment is the amount the owner of such investment might reasonably expect to receive upon its current sale.

Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements and Disclosure” - This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements.  Various inputs are used in determining the value of the Funds’ investments under FASB ASC Topic 820 guidance.  The inputs are summarized into three broad categories:

Level 1 includes valuations based on quoted prices of identical securities in active markets, including valuations for securities listed on a national or foreign stock exchange or investments in mutual funds, which are valued as a practical expedient at a daily reported NAV.

Level 2 includes valuations for which all significant inputs are observable, either directly or indirectly.  Direct observable inputs include broker quotes, closing prices of similar securities in active markets, closing prices for identical or similar securities in non-active markets or corporate action or reorganization entitlement values.  Indirect significant observable inputs include factors such as interest rates, yield curves, prepayment speeds or credit ratings.  Level 2 includes valuations for fixed income securities, securities priced by pricing services, OTC derivatives, centrally cleared swap agreements, broker quotes in active markets, securities subject to corporate actions, securities valued at amortized cost, international equity securities priced by an independent statistical fair value pricing service, swap agreements valued by pricing services or ADRs and GDRs for which quoted prices in active markets are not available.

Level 3 includes valuations based on inputs that are unobservable and significant to the fair value measurement including management’s own assumptions in determining the fair value of the investment.  Inputs used to determine the fair value of Level 3 securities include security specific inputs such as: credit quality, credit rating spreads, issuer news, trading characteristics, call features, anticipated cash flows or maturity; or industry specific inputs such as: trading activity of similar markets or securities, or changes in the security’s underlying index or comparable securities’ models.  Level 3 valuations include securities that are priced based on single source broker quotes, where prices may be unavailable due to halted trading, restricted to resale due to market events, newly issued or investments for which reliable quotes are otherwise not available.

To assess the continuing appropriateness of security valuations, the Sub-Administrator regularly compares prior day prices, prices of comparable securities and sales prices to the current day prices and challenges those prices exceeding certain tolerance levels with the pricing services or broker.  To substantiate Level 3 unobservable inputs, the Sub-Administrator uses a variety of techniques as appropriate to substantiate these valuation approaches including a regular review of key inputs and assumptions, transaction back-testing or disposition analysis and review of related market activity.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table summarizes each Fund’s investments in securities and other financial instruments as of April 30, 2012, by valuation level.

(1) Investments in other financial instruments are derivative instruments not reflected in the Schedules of Investments and include forward foreign currency contracts, futures contracts, written options and swap agreements.  Options purchased are included in investments in securities.  All derivatives, except for written options, are reflected at the unrealized appreciation/(depreciation) on the instrument.  Written options are reflected at value.

The Funds recognize transfers between levels as of the beginning of the period.  There were no material transfers into or out of Level 1, 2, or 3 during the period.

Recent Accounting Pronouncements - In April 2011, FASB released Accounting Standards Update (“ASU”) 2011-03 “Reconsideration of Effective Control for Repurchase Agreements”.  ASU 2011-03 is intended to improve financial reporting of repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem the financial assets before their maturity.  ASU 2011-03 eliminates the collateral maintenance provision that an entity may use to determine whether a transfer of securities in a repurchase agreement is accounted for as a sale or a secured borrowing.  ASU 2011-03 may cause certain dollar roll transactions that are currently accounted for as purchase and sale to be characterized as a secured borrowing transaction.  ASU 2011-03 is effective for the first interim or annual period beginning on or after December 15, 2011.  ASU 2011-03 will be effective for the Funds’ April 30, 2013 semiannual report.

In May 2011, FASB released ASU 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards”.  ASU 2011-04 further clarifies fair value measurement principles and requires additional disclosures.  Effective for interim and annual periods beginning after December 15, 2011, entities will need to disclose the amounts and reasons for any transfers between Level 1 and Level 2 securities; quantitative information relating to significant observable inputs, a narrative description of the valuation process, and a narrative description of the sensitivity of the fair value measurement to changes in unobservable or Level 3 fair valuations inputs.  ASU 2011-04 will be effective for the Funds’ January 31, 2013 Form N-Q.

In December 2011, FASB released ASU 2011-11 “Disclosures about Offsetting Assets and Liabilities”.  ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position.  ASU 2011-11 will enhance disclosures by requiring improved information about financial instruments and derivative instruments that meet the criteria for offsetting amounts in the balance sheet or are subject to a master netting arrangement.  The information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial positions, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments.  ASU 2011-11 is effective for the annual periods beginning on or after January 1, 2013 and the interim periods within those annual periods.

Management is currently evaluating the implications of these ASU’s and their impact on the Funds’ financial statements.

Curian Series Trust (Unaudited)

Notes to Financial Statements

April 30, 2012

Distributions to Shareholders — The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.  Net investment income is declared and distributed monthly for Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund and declared and distributed at least annually, if any, for Curian/WMC International Equity Fund.  Distributions from net realized capital gains, if any, will be distributed at least annually, to the extent they exceed available capital loss carry forwards.

Expenses - Expenses are recorded on an accrual basis.  Expenses of the Trust that are directly attributable to a specific Fund are charged to that Fund.  Other Trust level expenses are allocated to the Funds based on the average daily net assets of each Fund.

Security Transactions and Investment Income - Security transactions are recorded on the trade date for financial reporting purposes.  Dividend income, net of applicable withholding taxes, is recorded on the ex-dividend date.  Corporate actions involving foreign securities, including dividends, are recorded when the information becomes available.  Interest income, including level-yield amortization of discounts and premiums, is accrued daily.  A Fund may place a debt obligation on non-accrual status and reduce related interest income by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful.  A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.  Realized gains and losses are determined on the specific identification basis.

Foreign Taxes - The Funds may be subject to foreign taxes on income, gains on investments or foreign currency purchases and repatriation, a portion of which may be recoverable.  The Funds will accrue such taxes and recoveries as applicable, based upon their current interpretation of tax rules and regulations that exist in the markets in which they invest.

Foreign Currency Translations - The accounting records of each Fund are maintained in U.S. dollars.  Each business day, the market values of foreign securities, currency holdings and other assets and liabilities denominated in a foreign currency are translated into U.S. dollars based on current exchange rates.  Purchases and sales of investment securities, income receipts and expense payments are translated into U.S. dollars based on the respective exchange rates prevailing on the dates of such transactions.  The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of foreign securities.  Such fluctuations are included in net realized and unrealized gain or loss on investments.

Net realized gains and losses on foreign currency related items are considered ordinary income for tax purposes and arise from sales of foreign currencies; currency gains or losses realized between the trade and settlement dates on securities transactions; the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar amounts actually received or paid; and the realized gains or losses resulting from portfolio and transaction hedges.  Net unrealized gain or loss on foreign currency related items include gains and losses from changes in the value of assets and liabilities, other than investments in securities, resulting from changes in currency exchange rates.

Guarantees and Indemnifications — In the normal course of business, the Trust may enter into contracts that contain a variety of representations which provide general indemnifications for certain liabilities. Each Fund’s maximum exposure under these arrangements is unknown. However, since their commencement of operations, the Funds have not had claims or losses pursuant to these contracts and expect the risk of loss to be remote.

Under the Trust’s organizational documents, its officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds.  In addition, certain of theTrusts’ contracts with service providers contain general indemnification clauses.  The Funds’ maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Funds cannot be determined and the Funds have no historical basis for predicting the likelihood of any such claims.

Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period.  Actual results could differ from those estimates.

Organization and Offering Costs — Expenses incurred in connection with organizing and offering of the Funds were paid by Curian.  The Funds do not have an obligation to reimburse Curian or its affiliates for organizational and offering expenses paid on its behalf.

NOTE 3.  SECURITIES AND OTHER INVESTMENTS

Securities Lending and Securities Lending Collateral — A Fund may lend securities to certain brokers, dealers or other financial institutions in order to earn additional income.  The borrowers and the Funds’ securities lending agent exchange negotiated lender fees and the Funds receive a fee equal to a percentage of the net negotiated lender fees and the net income generated by the securities lending collateral held during each lending transaction.  The securities lending agent is authorized to loan securities on behalf of the Funds to approved borrowers and is required to maintain collateral at least equal to the value of the securities loaned based on the previous day’s value of the securities loaned, marked to market daily.  Any shortfalls are adjusted the next business day.  In the event of bankruptcy or other default of the borrower, a Fund could experience delays in liquidating the loan collateral or recovering the loaned securities and incur expenses related to enforcing its rights.  In addition, there could be a decline in the value of the collateral or in the value of the securities loaned while a Fund seeks to enforce its rights thereto and the Fund could experience subnormal levels of income or lack of access to income during that period.  The Funds also bear the risk of any deficiency in the amount of collateral available for return to a borrower due to a loss in an approved investment.  Each Fund is responsible for returning the full amount of collateral received for a particular loan when the borrower returns the applicable security.  JPMorgan Chase Bank, N.A. (“JPM Chase” or “Custodian”) serves as custodian and securities lending agent to the Trust.

U.S. Government Agencies or Government Sponsored Enterprises - Certain Funds may invest in U.S. government agencies or government sponsored enterprises.  U.S. Government securities are obligations of and, in certain cases, guaranteed by, the U.S. government, its agencies or instrumentalities.  Some U.S. Government securities, such as Treasury bills, notes and bonds, and securities guaranteed by GNMA, are supported by the full faith and credit of the U.S. government; others, such as those of the Federal Home Loan Bank, are supported by the right of the issuer to borrow from the U.S. Department of the Treasury (“U.S. Treasury”); others, such as those of the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), are supported by the discretionary authority of the U.S. government to purchase the agency’s obligations; and still others, such as those of the Student Loan Marketing Association, are supported only by the credit of the instrumentality.  U.S. Government securities may include zero coupon securities, which do not distribute interest on a current basis and tend to be subject to greater risk than interest paying securities of similar maturities.

Government-related guarantors (i.e., guarantors who are not backed by the full faith and credit of the U.S. government) include FNMA and the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”).  FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers.  Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. government.  FHLMC issues Participation Certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages.  FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. government.

FNMA and FHMLC were placed into conservatorship by the Federal Housing Finance Agency (“FHFA”).  As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and each enterprise’s assets.  In connection with the conservatorship, the U.S. Treasury entered into a Senior Preferred Stock Purchase Agreement with FNMA and FHLMC.  This agreement contains various covenants that severely limit each enterprise’s operations.  In exchange for entering into these agreements, the U.S. Treasury received senior preferred stock in each enterprise and warrants to purchase each enterprise’s common stock.  The U.S. Treasury created a new secured lending facility, which is available to FNMA and FHLMC as a liquidity backstop and created a temporary program to purchase mortgage-backed securities issued by FNMA and FHLMC.  FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations, associated with its mortgage-backed securities.

Unregistered Securities - A Fund may own certain investment securities, which are unregistered and thus restricted to resale. These securities may also be referred to as “private placements”.  Unregistered securities may be “illiquid” because there is no readily available market for sale of the securities.  Where future dispositions of the securities require registration under the 1933 Act, as amended, the Funds have the right to include those securities in such registration generally without cost to the Funds.  The Funds have no right to require registration of unregistered securities.

Repurchase Agreements - A Fund may invest in repurchase agreements.  A repurchase agreement involves the purchase of a security by a Fund and a simultaneous agreement by the seller, generally a bank or broker/dealer, to repurchase that security back from the Fund at a specified price and date or upon demand.  The underlying securities used as collateral for all repurchase agreements are held in safekeeping at the Fund’s Custodian or designated subcustodians under triparty repurchase agreements.  The market value of the collateral must be equal to or exceed at all times the total amount of the repurchase obligations, including interest.  In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of such collateral may decline.

Reverse Repurchase Agreements - A Fund may enter into reverse repurchase agreements.  A reverse repurchase agreement involves the sale of a security by a Fund and a simultaneous agreement by the purchaser, generally a bank or broker/dealer, to resell that security to the Fund at a specified price and date.  Securities sold under reverse repurchase agreements are reflected as a liability on the Statements of Assets and Liabilities.  Interest payments made are recorded as a component of interest expense on the Statements of Operations.  A reverse repurchase agreement involves the risk that the value of the security sold by the Fund may decline below the repurchase price of the security.  A Fund will segregate assets determined to be liquid at the Custodian or otherwise cover its obligations under reverse repurchase agreements.  Curian/PIMCO Total Return Fund’s average daily balance of reverse repurchase agreements and the weighted average interest rate for the period ended April 30, 2012 was $67,524,948 and 0.15%, respectively.  Curian/PIMCO Total Return Fund did not hold any reverse repurchase agreements at April 30, 2012.

Forward Sales Commitments — A Fund may purchase or sell forward sales commitments.  A forward sales commitment involves a Fund entering into a contract to purchase or sell securities for a fixed price at a future date beyond the customary settlement period.  The purchase of a forward sales commitment involves the risk of loss if the value of the security to be purchased declines before the settlement date while the sale of a forward sales commitment involves the risk that the value of the securities to be sold may increase before the settlement date.  A Fund may dispose of or renegotiate forward sales commitments after they are entered into, and may sell these securities before they are delivered, which may result in a realized gain or loss.

Delayed-Delivery Securities - A Fund may purchase or sell securities on a delayed delivery basis, including “To Be Announced” (“TBA”) or “To Be Acquired” securities.  These transactions involve a commitment by a Fund to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period.  In TBA transactions, a Fund commits to purchasing or selling securities for which all specific information is not yet known at the time of the trade, particularly the face amount and maturity date of the underlying securities.  When delayed-delivery purchases are outstanding, the Fund is required to have sufficient cash and/or liquid securities to cover its commitments on these transactions.

Notes to Financial Statements

When purchasing a security on a delayed-delivery basis, the Fund assumes the rights of ownership of the security, including the risk of price and yield fluctuations, and considers such fluctuations when determining its NAV.  A Fund may dispose of or renegotiate a delayed-delivery transaction after it is entered into, and may sell delayed-delivery securities before they are delivered, which may result in a realized gain or loss.  When a Fund has sold a security on a delayed delivery basis, the Fund does not participate in future gains or losses with respect to the security.  Securities purchased on a TBA basis are not settled until they are delivered to the Fund.  In connection with TBA transactions, Funds may maintain a short position related to certain securities.  In connection with these transactions, the Fund owns an equal amount of the securities or holds securities convertible (or exchangeable) into an equal amount of the securities, of the same issuer, as the position held short.  Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern the consideration of factors surrounding the settlement of certain purchases and sales made on a delayed-delivery basis by and between the Fund and select counterparties.  The Master Forward Agreements maintain provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination and maintenance of collateral.

NOTE 4.  FINANCIAL DERIVATIVE INSTRUMENTS

FASB ASC Topic 815, “Derivatives and Hedging” — This standard includes the requirement for qualitative disclosures about objectives and strategies for using derivative instruments and disclosures regarding credit related contingent features in derivative instruments; as well as requiring quantitative disclosures in the semiannual and annual financial statements about fair value, realized and unrealized gains and losses and volume of activity for derivative instruments.  Information about these instruments is disclosed in the context of each instrument’s primary underlying risk exposure which is categorized as credit, equity price, interest rate and foreign currency exchange rate risk.  The objectives, strategies and underlying risks for each instrument held by the Funds are discussed in the following paragraphs.

Options Transactions — A Fund may be subject to interest rate and foreign currency exchange rate risk in the normal course of pursuing its investment objective.  During the period, Curian/PIMCO Income Fund entered into options contracts to manage exposure to or hedge changes in interest rates and manage exposure to or hedge changes in foreign currencies and Curian/PIMCO Total Return Fund entered into option contracts to manage exposure to or hedge changes in interest rates.

An option is a contract that gives the purchaser of the option, in return for a premium paid, the right to buy a specified underlying instrument from the writer of the option (in the case of a call option), or to sell a specified underlying instrument to the writer of the option (in the case of a put option) at a designated price during the term of the option.  When a Fund purchases an option, the premium paid by the Fund is recorded as an asset and is subsequently marked-to-market to reflect the current value of the option.  Premiums paid for purchasing options which expire are treated as realized losses.  Premiums paid for purchasing options which are exercised or closed are added to the cost basis of the underlying investment or offset against the proceeds of the underlying investment transaction to determine realized gain or loss.  Purchasing call options tends to increase a Fund’s exposure to the underlying instrument.  Purchasing put options tends to decrease a Fund’s exposure to the underlying instrument.  The risks associated with purchasing options are limited to premiums paid and the failure of the counterparty to honor its obligation under the contract.  When a Fund writes a call or put option, the premium received by the Fund is recorded as a liability and is subsequently marked to market to reflect the current value of the option.  Premiums received from writing options which expire are treated as realized gains.  Premiums received from writing options which are exercised or closed are added to the proceeds of the underlying investment transaction or reduce the cost basis of the underlying investment to determine the realized gain or loss.  Writing call options tends to decrease a Fund’s exposure to the underlying instrument.  Writing put options tends to increase a Fund’s exposure to the underlying instrument.  The risk associated with writing an option that is exercised is that an unfavorable change in the price of the security underlying the option could result in a Fund buying the underlying security at a price higher than the current value or selling the underlying security at a price lower than the current market value.  There is also the risk a Fund may not be able to enter into a closing transaction if the market is illiquid.  Options written by a Fund do not give rise to counterparty credit risk, as they obligate the Fund, not the counterparty, to perform.

A Fund may also buy and sell (“write”) call and put options on swaps agreements (“swaptions”).  Swaptions are similar to options on securities except that instead of purchasing the right to buy or sell a security, the writer or purchaser of the swap option is granting or buying the right to enter into a previously agreed upon interest rate or credit default swap agreement at any time before the expiration of the option.  Swaptions are illiquid investments.

Futures Contracts - A Fund may be subject to interest rate risk in the normal course of pursuing its investment objective.  During the period, Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund entered into futures contracts to manage exposure to or hedge changes in interest rates, as an efficient means of adjusting overall exposure to certain markets as part of their investment strategy and as a substitute for investment in physical securities.  A futures contract is a standardized contract obligating two parties to exchange a specified asset at an agreed upon price and date.  Upon entering into a futures contract, the Fund is required to deposit with the broker or counterparty an amount of cash or cash equivalents equal to a certain percentage of the contract amount known as the “initial margin”.  The Fund receives from or pays to the counterparty an amount of cash equal to the daily fluctuation in the value of the contracts.  Such receipts or payments, known as the “variation margin”, are recorded by the Fund until the contracts are terminated at which time realized gains and losses are recognized.  Futures contracts involve to varying degrees, risk of loss in excess of the variation margin recorded by the Fund.  The primary risks associated with the use of futures contracts are the imperfect correlation between the change in market value of the securities held by a Fund or the change in the market value of an underlying entity and the prices of the futures contracts and the possibility a Fund may not be able to enter into a closing transaction because of an illiquid market.  With futures, there is minimal counterparty risk to a Fund since future contracts are exchange traded and the exchange’s clearinghouse, acting as counterparty to all exchange traded futures, guarantees the future contracts against default.

Forward Foreign Currency Contracts - A Fund may be subject to foreign currency exchange rate risk in the normal course of pursuing its investment objective.  During the period, Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund entered into forward foreign currency contracts to

minimize foreign currency exposure on investment securities denominated in foreign currencies and as part of their overall investment strategy.  A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date.  The use of forward foreign currency contracts does not eliminate fluctuations in the underlying prices of a Fund’s investment securities, but it does establish a fixed rate of currency exchange that can be achieved in the future.  The value of a forward foreign currency contract fluctuates with changes in foreign currency exchange rates.  Forward foreign currency contracts are marked-to-market daily and the change in value is recorded by a Fund as an unrealized gain or loss and as a receivable or payable from forward foreign currency contracts.  Upon settlement, or delivery or receipt of the currency, a realized gain or loss is recorded which is equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.  Forward foreign currency contracts involve market risk in excess of the receivable or payable related to forward foreign currency contracts recorded by the Funds.  Although contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase.  Additionally, a Fund could be exposed to the risk of a previously hedged position becoming unhedged if the counterparty to a contract is unable to meet the terms of the contract or if the value of the currency changes unfavorably to the value of the offsetting currency.

Swap Agreements - Swap agreements are bilaterally negotiated agreements between a Fund and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals.  Swap agreements are privately negotiated in the OTC market or may be executed in a multilateral or other trade facility platform, such as a registered exchange (“centrally cleared swaps”).  Swap agreements are illiquid investments.  If a Fund transacts in OTC swap agreements, they are a party to International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements (“ISDA Master Agreements”) with select counterparties.  The ISDA Master Agreements govern transactions in OTC derivatives, including swap agreements and forward foreign currency contracts, and maintain provisions for general obligations, representations, agreements, collateral and events of default or termination.  Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement.  Any election to early termination could be material to the financial statements.  The amount of collateral exchanged is based on provisions within the ISDA Master Agreements and is determined by the net exposure with the counterparty and is not identified for a specific swap agreement.  Collateral received from counterparties is included in receivable/payable for deposits with/from counterparties in the Statements of Assets and Liabilities.

Swap agreements are marked-to-market daily and change in value is recorded by a Fund as an unrealized gain or loss.  Swap premiums paid or received at the beginning of the measurement period which are recorded by the Fund represent payments made or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions relating to credit spreads, interest rates, currency exchange rates, and other relevant factors as appropriate.  These upfront payments are amortized over the life of the swap agreement and recorded as a realized gain or loss upon termination or maturity of the swap agreement.  A liquidation payment received or made at the termination of the swap agreement is recorded as a realized gain or loss.  Net periodic payments received or paid by a Fund are included as part of realized gain or loss.

Upon entering into a centrally cleared swap agreement, the Fund is required to deposit with the broker or counterparty an amount of cash or cash equivalent equal to a certain percentage of the centrally cleared swap agreement known as the “initial margin”.  The Fund receives from or pays to the counterparty an amount of cash equal to the daily fluctuation in the value of the centrally cleared swap agreement.  Such receipts or payments, known as the “variation margin”, are recorded by the Fund until the contracts are terminated at which time realized gains and losses are recognized.  Centrally cleared swap agreements involve to varying degrees, risk of loss in excess of the variation margin recorded by the Fund.

Entering into swap agreements involves, to varying degrees, elements of credit and market risk in excess of the unrealized gain or loss recorded by the Fund.  Such risks involve the possibility that there will be no liquid market for these agreements, that there may be unfavorable changes in interest rates or value of underlying securities and that the counterparty to the agreements may default on its obligation to perform.  In addition, entering into swap agreements involves documentation risk resulting from the possibility that the parties to a swap agreement may disagree as to the meaning of contractual terms in the agreement.  The credit risk associated with contracts is reduced by master netting arrangements to the extent that if an event of default occurs, all amounts with the counterparty are terminated and settled on a net basis.  A Fund’s overall exposure to credit risk subject to master netting arrangements can change substantially within a short period, as it is affected by each transaction subject to the arrangement.

Interest Rate Swap Agreements - A Fund may be subject to interest rate risk in the normal course of pursuing its investment objective.  During the period, Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund entered into interest rate swap agreements to manage duration, to manage interest rate and yield curve exposure and as a substitute for investment in physical securities.  Interest rate swap agreements involve the exchange by a Fund with another party of their respective commitments to pay or receive interest with respect to the notional amount of principal.  Forms of interest rate swap agreements that the Funds have entered into include:  fixed-for-floating rate swaps, under which a party agrees to pay a fixed rate in exchange for receiving a floating rate tied to a benchmark or floating-for-fixed rate swaps, under which a party agrees to pay a floating rate in exchange for receiving a fixed rate.

A Fund’s maximum risk of loss from counterparty credit risk for an interest rate swap agreement is the discounted net value of the cash flows to be received from the counterparty over the contract’s remaining life, to the extent this amount is positive.  This risk is mitigated by having a master netting arrangement between a Fund and the counterparty and by posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty.

Credit Default Swap Agreements — A Fund may be subject to credit risk in the normal course of pursuing its investment objective.  During the period, Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund entered into credit default swap agreements to manage credit exposure and as a

substitute for investment in physical securities.  Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return if a credit event occurs for the referenced entity, obligation or index.  A credit event is defined under the terms of each swap agreement and may include, but is not limited to, underlying entity default, bankruptcy, write-down, principal shortfall or interest shortfall.

As a seller of protection, a Fund will generally receive from the buyer of protection a fixed rate of income throughout the term of the swap if there is no credit event.  As a seller, a Fund adds leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap.  If a Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.  If a Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.  Until a credit event occurs, recovery values are determined by market makers considering either industry standard recovery rates or entity specific factors and considerations.  When a credit event occurs, the recovery value is determined by a facilitated auction, administered by ISDA, whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

A Fund may use credit default swap agreements on corporate or sovereign issues to provide a measure of protection against defaults of the issuers (i.e., to reduce risk where a Fund owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer’s default.  If a credit event occurs and cash settlement is not elected, a variety of other deliverable obligations may be delivered in lieu of the specific referenced obligation.  The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event).

A Fund may use credit default swap agreements on credit indices to hedge a portfolio of credit default swap agreements or bonds, to protect investors owning bonds against default and to speculate on changes in credit quality.  A credit index is a basket of credit instruments or exposures designed to represent a portion of the credit market.  These indices consist of reference credits that are considered to be the liquid entities in the credit default swap market based on the index sector.  Components of the indices may include, but are not limited to, investment grade securities, high yield securities, asset-backed securities and emerging market securities.  These components can be determined based upon various credit ratings within each sector.  Credit indices are traded using credit default swaps with standardized terms including a fixed spread and standard maturity dates.  An index credit default swap references all the issuers in the index, and if there is a credit event, the credit event is settled based on that issuer’s weight in the index.  The composition of the indices changes periodically, usually every six months, and for most indices, each issuer has an equal weight in the index.

Either as a seller of protection or a buyer of protection of a credit default swap agreement, a Fund’s maximum risk of loss from counterparty risk is the fair value of the agreement.  This risk is mitigated by having a master netting arrangement between the Fund and the counterparty and by posting collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty.  The maximum potential amount of future payments (undiscounted) that a Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement.  Notional amounts of all credit default swap agreements outstanding as of April 30, 2012, for which the Fund is the seller of protection, are disclosed in the Schedules of Investments.  These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

NOTE 5.  OTHER INVESTMENT RISKS

Foreign Securities Risk - Investing in securities of foreign companies and foreign governments generally involves special risks and considerations not typically associated with investing in U.S. companies and the U.S. government.  These risks include the potential for revaluation of currencies, different accounting policies, and future adverse political and economic developments.  Moreover, securities of many foreign companies and foreign governments and their markets may be less liquid and their prices may be more volatile than those of securities of comparable U.S. companies and the U.S. government.

Market, Credit and Counterparty Risk - In the normal course of business the Funds trade financial instruments and enter into financial transactions where the risk of potential loss exists due to changes in the market (“market risk”) or failure of the other party to a transaction to perform (“credit risk”).  Similar to credit risk, the Funds may be exposed to counterparty risk, or the risk that an institution or other entity with which the Funds have unsettled or open transactions will default.  Financial assets, which potentially expose the Funds to credit risk, consist principally of investments and cash due from counterparties (“counterparty risk”).  The extent of the Funds’ exposure to credit and counterparty risks in respect to these financial assets is incorporated within their carrying value as recorded in the Funds’ Statements of Assets and Liabilities.  For certain derivative contracts, the potential loss could exceed the value of the financial assets recorded in the financial statements.

NOTE 6.  INVESTMENT ADVISORY FEES AND TRANSACTIONS WITH AFFILIATES

Advisory, Sub-Advisory and Administration Fee - The Trust has an Investment Advisory Agreement and an Administration Agreement with Curian.  Pursuant to the Investment Advisory Agreement, Curian receives an annual fee accrued daily and paid monthly, at an annual rate of 0.15% of the average daily net assets of each Fund.

The Trust and Curian have an Investment Sub-Advisory Agreement with PIMCO for Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund and with WMC for Curian/WMC International Equity Fund.  The Funds pay the following fees to the Sub-Advisers:

	Assets	Fees
Curian/PIMCO Income Fund	All Assets	0.25	%
Curian/PIMCO Total Return Fund	Assets up to $3 billion(1)
	All assets	0.25	%
	When assets exceed $3 billion(2)
	$0 to $1 billion	0.25	%
	Amounts over $1 billion	0.225	%
Curian/WMC International Equity Fund	$0 to $250 million	0.45	%
	Amounts over $250 million	0.40	%

(1) When aggregate net assets of Curian/PIMCO Total Return Fund and Curian/PIMCO Income Fund of the Curian Series Trust and JNL/PIMCO Real Return Fund and JNL/PIMCO Total Return Bond Fund of the JNL Series Trust fall below $3 billion, this annual rate is applicable to all the amounts in the Curian/PIMCO Total Return Fund.

(2) When aggregate net assets of Curian/PIMCO Total Return Fund and Curian/PIMCO Income Fund of the Curian Series Trust and JNL/PIMCO Real Return Fund and JNL/PIMCO Total Return Bond Fund of the JNL Series Trust equal or exceed $3 billion, these annual rates are applicable to all the amounts in the Curian/PIMCO Total Return Fund.  The fee is computed based on the combined market value of the Curian/PIMCO Total Return Fund of Curian Series Trust and JNL/PIMCO Total Return Bond Fund of JNL Series Trust, and PIMCO will aggregate Curian/PIMCO Total Return Fund (Curian Series Trust) and JNL/PIMCO Total Return Bond Fund (JNL Series Trust) assets to derive an average fee to be applied to Curian/PIMCO Total Return Fund (Curian Series Trust) and JNL/PIMCO Total Return Bond Fund (JNL Series Trust).

Pursuant to the Administration Agreement, Curian receives an annual fee accrued daily and paid monthly, at an annual rate of 0.60% of the average daily net assets of Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund and 0.85% of the average daily net assets of Curian/WMC International Equity Fund.  Subject to the oversight of the Funds’ Board, Curian is responsible for managing the Funds’ business affairs and providing day-to-day administrative services to the Funds either directly or through others selected by it for the Funds.  In return for the fees paid under the Administration Agreement, Curian provides or procures all necessary administrative functions and services for the operation of the Funds.  In addition, Curian, at its own expense, arranges for legal, audit, fund accounting, transfer agency, custody, printing and mailing, a portion of the Chief Compliance Officer costs, and all other services necessary for the operation of each Fund.  Each Fund is responsible for trading expenses, including brokerage commissions, taxes, other non-operating expenses, errors and omission insurance, the fees and expenses of the disinterested Trustees and independent legal counsel to the disinterested Trustees, a portion of the costs associated with the Chief Compliance Officer, and certain nonrecurring or extraordinary expenses.

Fee Waiver and Expense Reimbursements - Curian agreed to waive its advisory fee and reduce the administration fee and/or reimburse other expenses to the extent necessary to reduce the annual expense ratios of the Funds, exclusive of brokerage costs, interest, taxes and dividend and extraordinary expenses, to 0.85% for the Curian/PIMCO Income Fund, 0.80% for the Curian/PIMCO Total Return Fund, and 1.32% for the Curian/WMC International Equity Fund until February 28, 2013.

Curian is entitled to recoup previously waived/reimbursed expenses for a period of up to three years following the fiscal year in which Curian waived its fee.  The amount of waived expenses for each Fund is recorded as expenses waived by Adviser in each Fund’s Statement of Operations.  During the period ended April 30, 2012, Curian did not recover any previously reimbursed expenses.  At April 30, 2012, the amount of potentially recoverable expenses was:

	Recoverable Expense		Expiration
Curian/PIMCO Income Fund	$	303,435	10/31/15
Curian/PIMCO Total Return Fund	934,049		10/31/15
Curian/WMC International Equity Fund	171,299		10/31/15

Other Service Providers - The Trust entered into a Transfer Agency Agreement and Shareholder Services Agreement with JNAM.  Curian has entered into a Sub-Administration and Fund Accounting Services Agreement with JFS, and is responsible for the compensation of JFS for services provided pursuant to such agreement.  Curian pays JNAM and JFS for such services through the fees earned pursuant to the Administration Agreement.

The Funds entered into an agreement with the Custodian in which the Custodian provides earnings credits for overnight cash balances held in the Funds’ custody accounts.  The earnings credits reduce the Funds’ custody fees which are paid by Curian, which then reimburses the Funds for such earnings credits.  The reimbursed earnings credits are included in other income in the Statements of Operations.

Distribution Agreement - The Trust entered into a Distribution Agreement with Curian Clearing LLC, an affiliate of Curian.  The Funds pay no expenses related to services provided under the Distribution Agreement.  The Distributor does not have any distribution and servicing arrangements with third parties to sell shares of the Funds.

Notes to Financial Statements

April 30, 2012

Directed Brokerage Commissions - A Sub-Adviser may allocate a portion of a Fund’s equity security transactions (subject to obtaining best execution of each transaction) through certain designated broker-dealers which will rebate a portion of the brokerage commissions to that Fund.  Any amount credited to the Fund is reflected as brokerage commissions recaptured in the Statements of Operations.

Deferred Compensation Plan — The Funds adopted a Deferred Compensation Plan whereby disinterested Trustees may defer the receipt of all or a portion of their compensation.  These deferred amounts, which remain as liabilities of the Funds, shall be treated as if invested and reinvested in shares of one or more affiliated funds at the discretion of the applicable Trustee.  These amounts represent general, unsecured liabilities of the Funds and vary according to the total returns of the selected Funds.  Liabilities related to deferred balances are included in payable for trustee fees in the Statements of Assets and Liabilities.  Increases or decreases related to the changes in value of deferred balances are included in trustee fees set forth in the Statements of Operations.

NOTE 7.  FEDERAL INCOME TAX MATTERS

Each Fund is a separate taxpayer for federal income tax purposes.  Each Fund intends to qualify as a regulated investment company (“RIC”) and to distribute substantially all net investment income and net capital gains, if any, to its shareholders and otherwise comply with Subchapter M of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies.  Therefore, no federal income tax provision is required.

The following information is presented on an income tax basis.  Differences between amounts for financial statements and federal income tax purposes are primarily due to timing and character differences in recognizing certain gains and losses on investment transactions.  To the extent there are differences between the amounts recognized for financial statements and federal income tax purposes that are permanent in nature, such amounts are reclassified within the capital accounts based on their federal income tax treatment; temporary differences do not require reclassification.  Permanent differences may include but are not limited to the following:  foreign currency reclassifications, market discount or paydown reclassifications, reclassifications on the sale of PFIC or REIT securities, net operating losses, accounting treatment of notional principal contracts and distribution adjustments.  These reclassifications have no impact on net assets.

As of April 30, 2012, the cost of investments and the components of net unrealized appreciation for U.S. federal income tax purposes were as follows:

	Tax Cost of Investments		Gross Unrealized Appreciation		Gross Unrealized Depreciation			Net Unrealized Appreciation
Curian/PIMCO Income Fund	$	458,977,724	$	10,951,771	$	(515,478	)	$	10,436,293
Curian/PIMCO Total Return Fund	1,209,688,698		19,960,724		(286,965		)	19,673,759
Curian/WMC International Equity Fund	228,296,077		21,261,317		(2,425,734		)	18,835,583

FASB ASC Topic 740 “Income Taxes” provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements.  FASB ASC Topic 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing each Fund’s tax return to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority.  Tax positions not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax expense in the current year.  FASB ASC Topic 740 requires that management evaluate the tax positions taken in the 2011 return which remains subject to examination, by the Internal Revenue Service.  This return is not subject to examination by any other tax jurisdictions.  Management completed an evaluation of the Funds’ tax positions and based on that evaluation, determined that no provision for federal income tax was required in the Funds’ financial statements for the period ended April 30, 2012.

NOTE 8.  SUBSEQUENT EVENTS

Management has evaluated subsequent events for the Funds through the date the financial statements are issued, and has concluded there are no events that require adjustments to the financial statements or disclosure in the footnotes.

Curian Series Trust

Additional Disclosures (Unaudited)

April 30, 2012

Disclosure of Fund Expenses.  Shareholders incur ongoing costs, which include costs for portfolio management, administrative services and other operating expenses.  Operating expenses such as these are deducted from each Fund’s gross income and directly reduce the final investment return.  These expenses are expressed as a percentage of the Fund’s average net assets; this percentage is known as the Fund’s expense ratio.  The examples below use the expense ratio and are intended to help the investor understand the ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds.  The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

Expenses Using Actual Fund Return.  This section provides information about the actual account values and actual expenses incurred by the Fund.  Use the information in this section, together with the amount invested, to estimate the expenses paid over the period.  Simply divide the 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 first section under the heading entitled “Expenses Paid During Period” to estimate the expenses paid during this period.

Expenses Using Hypothetical 5% Return.  The information in this section can be used to compare each Fund’s costs with those of other mutual funds.  It assumes that the Fund had an annual 5% return before expenses during the year, but that the expense ratio for the period is unchanged.  This example is useful in making comparisons because the SEC requires all mutual funds to make the 5% calculation.  The Funds have less than 6-month’s operating history.  The amounts reported under Expenses Using Hypothetical 5% Return are not comparable to the amounts reported in Expenses Using Actual Fund Return.

	Expenses Using Actual Fund Return								Expenses Using Hypothetical 5% Return
	Beginning Account Value 11/03/2011		Ending Account Value 4/30/2012		Annualized Net Expense Ratios		Expenses Paid During Period		Beginning Account Value11/03/2011		Ending Account Value 4/30/2012		Annualized Net Expense Ratios		Expenses Paid During Period
Curian/PIMCO Income Fund	$	1,000.00	$	1,054.60	0.85	%	$	4.29	$	1,000.00	$	1,020.41	0.85	%	$	4.22
Curian/PIMCO Total Return Fund	1,000.00		1,042.40		0.80		4.02		1,000.00		1,020.65		0.80		3.98
Curian/WMC International Equity Fund	1,000.00		1,081.00		1.32		6.75		1,000.00		1,018.09		1.32		6.55

Expenses paid during the period are equal to the annualized net expense ratio, multiplied by the average account value over the period, multiplied by the number of days in the period, then divided by the number of days in the most recent 12-month period (to reflect the most recent 6-month period).

Quarterly Portfolio Holdings.  The Funds filed a complete schedule of portfolio holdings with the U.S. Securities and Exchange Commission (“SEC”) for the first quarter of the fiscal year on Form N-Q.  The Funds’ Form N-Q is available on the SEC’s website at www.sec.gov.  The Form N-Q may be reviewed and copied at the SEC’s Public Reference Room in Washington, DC, and information on the operation of the Public Reference Room may be obtained by calling 800-SEC-0330.  It is also available upon request from the registrant by calling the Funds toll-free at 1-866-255-1935.

Proxy Voting Guidelines.  The Board has adopted the proxy voting policy and procedures (“Policy”) of the Funds’ Adviser, pursuant to which the Board has delegated proxy voting responsibility to the Adviser, and pursuant to which the Adviser has delegated proxy voting responsibility to each of the Sub-Advisers.  The Trust has adopted each of the Sub-Adviser’s proxy voting policies and procedures (“Procedures”).

The Policy is designed to promote accountability of the company’s management to its shareholders and to align the interests of management with those shareholders.  The Sub-Advisers generally review each matter on a case-by-case basis in order to make a determination of how to vote in a manner that best serves the interests of Fund shareholders.  The Sub-Advisers may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweigh the benefits derived from exercising the right to vote.  For example, Curian shall permit a Sub-Adviser to abstain from voting a proxy for securities that have been loaned by the Fund and would have to be recalled in order to submit a proxy vote.  In addition, the Sub-Advisers will monitor situations that may result in a conflict of interest in accordance with their policies and procedures.  A description of the policies and procedures used by the Funds to vote proxies relating to the portfolio securities and information on how the Funds voted proxies relating to portfolio securities during the 12-month period ended June 30 are available (1) without charge, upon request by calling 1-877-874-4143 (Curian Client Services), (2) on Curian Capital’s website at www.curian.com, and (3) on the SEC’s website at www.sec.gov.

CURIAN SERIES TRUST

APPROVAL OF CURIAN SERIES TRUST’S (THE “TRUST”)

INVESTMENT ADVISORY AND SUB-ADVISORY AGREEMENTS

The Board of Trustees of the Trust (“Board”) oversees the management of each series of the Trust (each a “Fund”) and, as required by law, determines whether to approve and, after the initial term, continue the Trust’s advisory and sub-advisory agreement(s).

At a meeting on November 10, 2010, the Board, including all of the Trustees who are not considered “interested persons” as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the “Independent Trustees”), considered information relating to the approval of the investment advisory and management agreement between Curian Capital, LLC (“Curian” or the “Adviser”) and the Trust (the “Advisory Agreement”), on behalf of Curian/PIMCO Income Fund, Curian/PIMCO Total Return Fund and Curian/WMC International Equity Fund (the “Funds”), and information relating to the approval of the investment sub-advisory agreement between Curian and Pacific Investment Management Company (“PIMCO”) with respect to Curian/PIMCO Income Fund and Curian/PIMCO Total Return Fund and the investment sub-advisory agreement between Curian and Wellington Management Company LLP (“Wellington”) with respect to Curian/WMC International Equity Fund (collectively, the “Sub-Advisory Agreements”).  The term Agreements refers to the Advisory Agreement and applicable Sub-Advisory Agreements and the term Sub-Adviser refers to PIMCO and Wellington.  In advance of the meeting, independent legal counsel for the Independent Trustees requested that certain information be provided to the Board relating to the Board’s consideration of the Agreements.  The Board received, and had the opportunity to review, this and other materials, ask questions and request further information in connection with its consideration.  At the conclusion of the Board’s discussion, the Board approved the PIMCO Sub-Advisory Agreement effective July 1, 2011 and the Wellington Sub-Advisory Agreement effective September 2, 2011 through February 28, 2013.

For each of the Funds, Curian, PIMCO and Wellington provided detailed information including information related to the following factors:  (1) the nature, quality and extent of the services each proposed to provide, (2) the investment performance of similarly managed strategies, (3) the cost of the services and the anticipated profits proposed to be realized by the Adviser and Sub-Advisers from the relationship with the Funds and comparative expense information, (4) whether economies of scale may be realized as the Funds grow and whether the fee structure reflects the economies of scale for the Funds’ investors, and (5) other “fall-out” benefits that could be realized by Curian or a Sub-Adviser (i.e., ancillary benefits derived by Curian or its affiliates from Curian’s relationship with the Funds).  In its deliberations, the Board, in exercising its business judgment, did not identify any single factor that alone was responsible for the Board’s decision to approve the Agreements.

Before approving the Agreements, the Independent Trustees met in executive session with their independent legal counsel to consider the materials provided by Curian, PIMCO and Wellington and the terms of the Agreements.  Based on its evaluation of those materials, the Board, including the Independent Trustees voting separately, determined that the Advisory Agreement would be in the best interests of the shareholders of each Fund and that each Sub-Advisory Agreement would be in the best interests of the shareholders of each respective Fund.  In reaching its conclusions, the Board considered the following:

Nature, Quality and Extent of Services

The Board examined the nature, quality and extent of the services to be provided by Curian and the Sub-Advisers and took note of the following:

The Advisory Agreement provides that the Adviser will furnish the Funds with investment advisory services, subject to the supervision of the Board, and in conformity with the stated policies of the applicable Fund.  The Adviser proposed to charge advisory fees at an annual rate of 0.15% of the average daily net assets of each Fund.  The Adviser proposed to engage Sub-Advisers to conduct the investment programs of the Funds, including the purchase, retention, and sale of portfolio securities.  The Board noted that the Funds, not the Adviser, would bear the cost of the sub-advisory fees.  The Adviser would be responsible for monitoring the activities of the Sub-Advisers, and reporting on such activities to the Board.

The Adviser also proposed to manage, in coordination with the Sub-Advisers, the affairs of the Funds to assure compliance with the current prospectus of the Funds, current tax rules, regulatory and statutory requirements and other applicable legal requirements.  The Adviser also proposed to coordinate information required by the Board with the Sub-Advisers.

Curian proposed to waive such portion of its advisory fee and reduce its administration fee and/or reimburse other expenses of the Funds during the period ending one year from the effective date of the Trust’s registration statement, to the extent necessary to limit the total operating expenses of each Fund, exclusive of brokerage costs, interest, taxes and dividend and extraordinary expenses, to an annual rate (as a percentage of the average daily net assets of each Fund) of 0.85% for the Curian/PIMCO Income Fund, 0.80% for the Curian/PIMCO Total Return Fund and 1.32% for the Curian/WMC International Equity Fund.

The Adviser provided the Board with information about the Adviser’s personnel who will provide certain investment advisory oversight services to the Fund, and the Adviser’s organizational structure, financial condition, and regulatory history, and overall compliance culture.

Each Sub-Advisory Agreement provides that the respective Sub-Adviser shall furnish investment advisory or trading services in connection with the management of the Fund.  Under each Sub-Advisory Agreement, the respective Sub-Adviser, subject to the supervision of the Adviser, is responsible for managing the assets of the Fund in accordance with the Fund’s investment objectives, investment program and policies.  Each Sub-Adviser has provided information on the Sub-Adviser’s key personnel that provide investment management services to the respective Fund, as well as the Sub-Adviser’s compliance and regulatory history.

Investment Performance of the Fund

The Board could not consider the performance of each Fund as the Funds had not yet commenced operations.  The Board, however, considered the performance of a similarly managed strategy, including how the similarly managed strategy performed versus its primary benchmark (“benchmark”) index. The performance reviewed by the Board was for the one-, three-, five-, and ten-year periods ended on September 30, 2010.

Curian/PIMCO Income Fund.  The Board noted that the similarly managed strategy significantly outperformed its benchmark and the Lipper universe average for the one-, three-, and five-year periods.  The similarly managed fund significantly outperformed the Lipper universe average for the ten-year period.  The Board concluded it would be in the best interests of the Fund and its potential shareholders to approve the Agreements based on the long-term performance of the similarly managed strategy.

Curian/PIMCO Total Return Fund.  The Board noted that the similarly managed strategy significantly outperformed its benchmark and the Lipper universe average for the one-, three-, five-, and ten-year periods.  The Board concluded it would be in the best interests of the Fund and its potential shareholders to approve the Agreements based on the long-term performance of the similarly managed strategy.

Curian/Wellington International Equity Fund.  The Board noted that the similarly managed strategy outperformed its benchmark and the Lipper universe average for the one-, three-, five-, and ten-year periods.  The Board concluded it would be in the best interests of the Fund and its potential shareholders to approve the Agreements based on the long-term performance of the similarly managed strategy.

Costs of Services

The Board reviewed the fees proposed to be paid to Curian and each Fund’s Sub-Adviser.  The Board reviewed fee and expense information as compared to that of comparable funds managed by other advisers.  Using information provided by an independent data service, the Board evaluated the Fund’s advisory fees compared to the average advisory fees for other funds similar in size, character and investment strategy (the “peer group”).  The Board also considered the Fund’s sub-advisory fee and compared that to the average sub-advisory fee of the peer group. The Board noted that each Fund’s sub-advisory fee would be paid by each respective Fund.

Further detail considered by the Board regarding the advisory and sub-advisory fees of the Fund is set forth below:

Curian/PIMCO Income Fund.  The Fund’s advisory fee (net of waivers) is significantly below the Lipper peer group average.  The sub-advisory fee and total expense (net of waivers) ratios are below the respective peer group averages. The Board concluded that the proposed advisory and sub-advisory fees are in the best interests of the Fund and its potential shareholders in light of the services provided.

Curian/PIMCO Total Return Fund.  The Fund’s advisory fee and total adviser fee (net of waivers) are significantly below the Lipper peer group averages.  The sub-advisory fee is consistent with the peer group average while the total expense ratio (net of waivers) is slightly higher than the peer group average. The Board concluded that the proposed advisory and sub-advisory fees are in the best interests of the Fund and its potential shareholders in light of the services provided.

Curian/Wellington International Equity Fund.  The Fund’s advisory fee (net of waivers) is significantly below the Lipper peer group average.  The sub-advisory fee is consistent with the peer group and the total expense ratio (net of waivers) is below the respective peer group average ratio. The Board concluded that the proposed advisory and sub-advisory fees are in the best interests of the Fund and its potential shareholders in light of the services provided.

Economies of Scale

The Board noted that Curian has not proposed breakpoints in its advisory fee schedule.  Given that Curian is offsetting all of its advisory fees against the Separately Managed Accounts Program Fees that Curian charges to its separately managed account clients (to the extent that such fees are not already waived to meet the Funds’ expense limitations), the Board determined that breakpoints in the advisory fee would not result in meaningful benefit to shareholders (who would all be clients in Curian’s separately managed account program) at the current time.

The Board also considered that the sub-advisory fee rates have been separately negotiated between the Adviser and each Sub-Adviser at arm’s length.  These sub-advisory fees would be paid directly by the Funds to the Sub-Advisers.  In certain cases, the Sub-adviser has agreed to breakpoints in the sub-advisory fee rate.  Thus, shareholders of the Fund benefit directly from any breakpoints in the sub-advisory fee rates.

Profitability

The Board did not consider information concerning the costs incurred and profits proposed to be realized by the Adviser or the Sub-Advisers since the Funds have not yet commenced operations.

Other Benefits to Affiliates of Curian

In evaluating the benefits that will accrue to the Adviser, Curian reviewed the Trust as a whole. Through its relationship with the Funds, Curian, and its affiliates recognize that they serve the Funds in various capacities, including as adviser, administrator, sub-administrator, transfer agent and distributor, and that they receive compensation from the Funds in connection with providing certain of these services to the Funds.
