The Fund does not seek to distribute any predetermined amount at maturity.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;The Fund primarily invests in U.S. dollar denominated corporate bonds rated investment grade at the time of purchase. Investment grade is defined as bonds rated BBB- or higher by S&amp;amp;P Global Ratings and/or Fitch Ratings Inc., Baa3 or higher by Moody's Investors Service, Inc., or equivalent ratings by another registered nationally recognized statistical rating organization (&#x201c;NRSRO&#x201d;), or, if unrated by an NRSRO, of comparable quality as determined by the Adviser.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; The &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Fund may invest up to 10% of its net assets in corporate bonds rated below investment grade at the time of purchase (commonly known as &#x201c;junk&#x201d; bonds). As of the date of this Prospectus, it is expected that a significant&#160;portion of the Fund will comprise securities of companies in the financial, industrial and utilities sectors, although this may change from time to time.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;The Fund may use derivative instruments (primarily futures contracts, interest rate and credit default swaps, and options on treasury futures) to manage yield, interest rate exposure (also known as duration), weighted average maturity, and exposure to credit quality. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;In the Fund's target maturity year, proceeds from corporate bonds maturing prior to the Fund's liquidation date may be reinvested in cash and cash equivalents, including, but not limited to, shares of money market funds (including money market funds advised by the Adviser). The Fund seeks to remain fully invested in corporate bonds to the extent possible; however, leading up to the Fund's target maturity date, the Fund's cash and cash equivalents holdings may increase and the Fund's investment in corporate bonds may be less than 80% of the Fund's net assets.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;The Adviser actively manages the Fund using a risk-aware, top-down approach combined with bottom-up security selection to construct a portfolio that seeks to overweight the most attractive sectors and issuers. The Adviser develops long-term structural and intermediate-term cyclical views by analyzing macroeconomic factors, financial conditions, as well as consumer, industry, and sector trends. Individual securities are then identified for investment through rigorous fundamental research, including financial analysis of the applicable cash flows, capital structure, industry, and issuer-specific fundamentals. The Adviser's analysis also includes an assessment of relative value and liquidity trends, which are supported by the performance of similar instruments through economic and market cycles. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;The Adviser may consider selling a security when one of the selection characteristics no longer applies, when the Adviser believes that the valuation has become excessive, or when more attractive alternatives are identified. The Fund may engage in active and frequent trading of its portfolio securities. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The Fund should not be confused with a target date fund, which has assets that are managed according to a particular investment strategy that converts fund assets to conservative investments over time.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets.

To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. &lt;/span&gt;</oef:RiskTextBlock>

Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time.

Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.&lt;/span&gt;</oef:RiskTextBlock>

Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets.

Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;to control the U.S. (and other) government budgets.

To the extent the Fund invests in a money market fund managed by the Adviser, the Adviser may have an incentive to take into account the effect on such money market fund in determining whether, and under what circumstances, to purchase or sell shares in that money market fund. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund.&lt;/span&gt;</oef:RiskTextBlock>

To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds. &lt;/span&gt;</oef:RiskTextBlock>

When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage.&lt;/span&gt;</oef:RiskTextBlock>

This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes.&lt;/span&gt;</oef:RiskTextBlock>

The bonds are primarily rated investment grade at the time of purchase, which is defined as bonds rated BBB- or higher by S&amp;amp;P Global Ratings and/or Fitch Ratings Inc., Baa3 or higher by Moody's Investors &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Service, Inc., or equivalent ratings by another registered nationally recognized statistical rating organization (&#x201c;NRSRO&#x201d;), or, if unrated by an NRSRO, of comparable quality as determined by the Adviser.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; The Fund may invest up &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;to 10% of its net assets in municipal bonds rated below investment grade at the time of purchase (commonly known as &#x201c;junk&#x201d; bonds).&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;The Fund may use derivative instruments (primarily futures contracts, interest rate and credit default swaps, and options on treasury futures) to manage yield, interest rate exposure (also known as duration), weighted average maturity, and exposure to credit quality. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;In the Fund's target maturity year, proceeds from municipal bonds maturing prior to the Fund's liquidation date may be reinvested in cash and cash equivalents, including, but not limited to, shares of money market funds (including money market funds advised by the Adviser).

The Adviser develops long-term structural and intermediate-term cyclical views by analyzing macroeconomic factors, financial conditions, as well as consumer, industry, and sector trends.

The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets.

To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. &lt;/span&gt;</oef:RiskTextBlock>

The values of municipal obligations may be adversely affected by local political and economic conditions and developments. In addition, the values of municipal obligations that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status&#160;may cause interest received and distributed by the Fund to shareholders to be taxable and may result in a significant decline in the values of such municipal obligations.&lt;/span&gt;</oef:RiskTextBlock>

There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets.

A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a &#x201c;floating&#x201d; NAV that will fluctuate along with changes in the market-based value of fund assets.

To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. &lt;/span&gt;</oef:RiskTextBlock>

In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.&lt;/span&gt;</oef:RiskTextBlock>

Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations.&lt;/span&gt;</oef:RiskTextBlock>

Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, another component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.&lt;/span&gt;</oef:RiskTextBlock>

If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis.

Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a &#x201c;floating&#x201d; NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. To the extent the Fund invests in a money market fund managed by the Adviser, the Adviser may have an incentive to take into account the effect on such money market fund in determining whether, and under what circumstances, to purchase or sell shares in that money market fund.

When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage.&lt;/span&gt;</oef:RiskTextBlock>

Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value).

This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices.
