with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the 
Fund for the time periods indicated whether or not you redeem all of your shares at the end of those 
periods (except as indicated with respect to Class C shares). The Example reflects Class C shares converting 
into Investor Class shares in years 9-10; expenses could be lower if you are eligible to convert to Class 
A shares instead. The Example also assumes that your investment has a 5% return each year and that the 
Fund's operating expenses remain the same. The Example reflects the contractual fee waiver and/or expense

its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result 
in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected 
in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent 
fiscal year, the Fund's portfolio turnover rate was 25% of the average value of its portfolio.   &lt;/p&gt;</rr:PortfolioTurnoverTextBlock>

invests at least 80% of its assets (net assets plus any borrowings for investment purposes) in a portfolio 
of master limited partnerships (&#x201c;MLPs&#x201d;) and MLP-related investments (together, &#x201c;MLP Investments&#x201d;). 
The Fund&#x2019;s MLP Investments may include, but are not limited to, investments that offer economic exposure 
to MLPs in the form of common or subordinated units issued by MLPs, &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;securities of entities holding primarily general partner or managing member interests 
in MLPs, debt securities of MLPs, securities that are derivatives of interests in MLPs, including indirect 
ownership interests in an MLP issued by an MLP affiliate (&#x201c;I-Shares&#x201d;) and businesses that operate 
like MLP Investments and have the economic characteristics of MLP Investments but are organized and taxed 
as &#x201c;C&#x201d;corporations or as limited liability companies. The Fund is non-diversified, which means it 
may invest a greater percentage of its assets in a limited number of issuers than a diversified fund, 
and it may invest in companies of any market capitalization size. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Fund focuses primarily 
on midstream MLP Investments (&#x201c;Midstream MLPs&#x201d;) whose business models are often referred to as &#x201c;toll 
road&#x201d; businesses. Midstream MLPs collect, gather, transport and store natural resources and their byproducts 
(primarily crude oil, natural gas and refined petroleum products), generally without taking ownership 
of the physical commodity. Midstream MLPs may also operate ancillary businesses including the marketing 
of the products and logistical services. The Fund may also invest in MLPs involved in other segments 
of the natural resources sector, including propane, coal and shipping MLPs, as well as upstream MLPs 
focused on exploration and production of natural resources.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Cushing&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&lt;sup&gt;&#xae; &lt;/sup&gt;&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Asset 
Management, LP, the Fund&#x2019;s Subadvisor, seeks MLP Investments that have distributions that, in the Subadvisor&#x2019;s 
view, are attractive relative to comparable MLP Investments and available unit pricing. The Subadvisor 
also focuses on MLP Investments with operations in the development, production, processing, refining, 
transportation, storage and marketing of natural resources. Among other things, the Subadvisor uses fundamental, 
proprietary research to seek to identify the most attractive MLP Investments with favorable distribution 
yields and distribution growth prospects. Distributions made by the Fund to shareholders may be considered 
dividend income, non-taxable returns of capital, capital gain or a combination thereof.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;MLPs are generally treated as partnerships for U.S. federal income tax purposes 
and are generally organized under state law as limited partnerships or limited liability companies. To 
be treated as a partnership for U.S. federal income tax purposes, an MLP must derive at least 90% of 
its gross income for each taxable year from qualifying sources, including natural resources-based activities 
such as the exploration, development, mining, production, processing, refining, transportation, storage 
and certain marketing of mineral or natural resources. Currently, most MLPs operate in the natural resources, 
shipping or real estate sectors. Therefore, the Fund will, in normal circumstances, invest more than 
25% of its assets (or concentrate its investments) in the natural resources industry, including MLPs 
operating in such industry. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Fund may also invest in foreign securities, 
including among other things, Canadian royalty trusts and Canadian exploration and production companies. 
A Canadian royalty trust is an oil, gas or mineral company that is organized as a trust rather than as 
a traditional corporation and holds commodity producing properties.  Canadian exploration and production 
companies are energy companies which focus on searching for and extracting oil and gas. An issuer of 
a security is considered to be a U.S. or foreign issuer based on the issuer's "country of risk" (or similar 
designation) as determined by a third party such as Bloomberg.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

cause the Fund to underperform other funds with similar investment objectives and strategies. Such changes

for potentially prolonged periods that may result in: (i) increased market volatility; (ii) reduced market 
liquidity; and (iii) increased redemptions of shares. Certain securities may be difficult to value under

at the partnership level. Rather, each partner is allocated a share of the partnership's income, gains, 
losses, credits, deductions and expenses. A change in current tax law, a change in the underlying business 
mix of a given MLP, or an elective change by an MLP itself could result in an MLP being treated, after 
a taxable conversion, as a corporation for U.S. federal income tax purposes, which would result in such 
MLP being subject to U.S. federal income tax on its taxable income as well as additional state and local 
taxes. The treatment of an MLP as a corporation for U.S. federal income tax purposes would, among other 
consequences, have the effect of reducing the amount of cash available for distribution by the MLP. Thus, 
to the extent the MLPs owned by the Fund are treated as corporations for U.S. federal income tax purposes 
and to the extent the Fund invests in MLP-related investments or other non-partnership entities, this 
could result in a reduction of the value of your investment in the Fund and lower income.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; text-indent:-18.0pt; font-weight:normal; margin-left:18.0pt; font-style:normal;"&gt;&lt;span style="font-size:8.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:10.0pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The 
portion, if any, of a distribution received by the Fund as the holder of an MLP equity security that 
is offset by the MLP's tax deductions or losses generally will be treated as a return of capital to the

Fund that are considered return of capital will not be known until the Fund receives a Form 1065, Schedule 
K-1 with respect to each of its MLP investments. Distributions received by shareholders from the Fund 
that are treated as return of capital would not be subject to U.S. federal income tax, but would have 
the effect of reducing a shareholder's basis in the shares of the Fund, which would cause gains to be 
higher, or losses to be lower, upon the sale of shares by such shareholder.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; text-indent:-18.0pt; font-weight:normal; margin-left:18.0pt; font-style:normal;"&gt;&lt;span style="font-size:8.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:10.0pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Individuals and

income from MLPs through 2025. The Fund will not be eligible for the 20% deduction and as of yet does 
not have regulatory authority to pass through the 20% deduction for MLP net taxable income, if any, to 
Fund shareholders. As a result, in comparison, investors investing directly in MLPs generally would be 
eligible for the 20% deduction for any such taxable income from these investments while investors investing 
in MLPs held indirectly, if any, through the Fund (unless applicable regulatory authority is released) 
would not be eligible for the 20% deduction for their share of such taxable income.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; text-indent:-18.0pt; font-weight:normal; margin-left:18.0pt; font-style:normal;"&gt;&lt;span style="font-size:8.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:10.0pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Changes in tax

economy, given that the United States is Canada&#x2019;s largest trading partner and foreign investor. Reduction

The risks of investing in debt or fixed-income securities include (without limitation): (i) credit risk, 
e.g., the issuer or guarantor of a debt security may be unable or unwilling (or be perceived by market 
participants, rating agencies, pricing services or otherwise as unable or unwilling) to make timely principal 
and/or interest payments or otherwise honor its obligations, or changes in an issuer&#x2019;s credit rating 
or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may affect the value of the Fund&#x2019;s investments; 
(ii) maturity risk, e.g., a debt security with a longer maturity may fluctuate in value more than one 
with a shorter maturity; (iii) market risk, e.g., low demand for debt securities may negatively impact 
their price; (iv) interest rate risk, e.g., when interest rates go up, the value of a debt security generally 
goes down, and when interest rates go down, the value of a debt security generally goes up (long-term 
debt securities are generally more susceptible to interest rate risk than short-term debt securities); 
and (v) call or prepayment risk, e.g., during a period of falling interest rates, the issuer may redeem 
a security by repaying it early, which may reduce the Fund&#x2019;s income if the proceeds are reinvested 
at lower interest rates.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Interest rate risk is the risk that the value of the Fund&#x2019;s 
investments in fixed-income or debt securities will change because of changes in interest rates&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Changes in interest rates (or the expectation of such changes) or a lack of 
market participants may lead to decreased liquidity and increased volatility in the fixed-income or debt 
markets, making it more difficult for the Fund to sell its fixed-income or debt holdings. Decreased liquidity 
in the fixed-income or debt markets also may make it more difficult to value some or all of the Fund&#x2019;s 
fixed-income or debt holdings. For most fixed-income investments, when market interest rates fall, prices 
of previously-issued fixed-rate debt securities rise. However, when market interest rates fall, prices 
of certain variable and fixed-rate debt securities may be adversely affected (i.e., falling interest 
rates bring the possibility of prepayment risk, as an instrument may be redeemed before maturity). Very 
low or negative interest rates may magnify interest rate risk. Low interest rates (or negative interest 
rates) may magnify the risks associated with rising interest rates. There is a risk that the income generated 
by investments may not keep pace with inflation. Actions by governments and central banking authorities 
can result in increases or decreases in interest rates. Periods of higher inflation could cause such 
authorities to raise interest rates, which may adversely affect the Fund and its investments. Changing 
interest rates, including rates that fall below zero, may have unpredictable effects on markets, may 
result in heightened market volatility and may detract from Fund performance to the extent the Fund is 
exposed to such interest rates and/or volatility. Other factors that may affect the value of debt securities 
include, but are not limited to, economic, political, public health, and other crises and responses by 
governments and companies to such crises. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;Not all U.S. government debt securities are guaranteed by the U.S. government&#x2014;some 
are backed only by the issuing agency, which must rely on its own resources to repay the debt. The Fund&#x2019;s 
yield will fluctuate with changes in short-term interest rates.&lt;/p&gt;</rr:RiskTextBlock>

mid-cap companies may be subject to greater price volatility, significantly lower trading volumes, cyclical, 
static or moderate growth prospects and greater spreads between their bid and ask prices than securities 
of larger companies. Smaller capitalization companies frequently rely on narrower product lines and niche 
markets and may be more vulnerable to adverse business or market developments.&#160; Securities issued by 
larger companies may have less growth potential and may not be able to attain the high growth rates of 
successful smaller companies, especially during strong economic periods.&#160; In addition, larger companies 
may be less capable of responding quickly to competitive challenges and industry changes, including those 
resulting from improvements in technology, and may suffer sharper price declines as a result of earnings 
disappointments.&#160; There is a risk that the securities issued by companies of a certain market capitalization 
may underperform the broader market at any given time.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The Fund&#x2019;s investments may be illiquid at the time of purchase or liquid at the time of purchase and 
subsequently become illiquid due to, among other things, events relating to the issuer of the securities, 
market events, operational issues, economic conditions, investor perceptions or lack of market participants. 
The lack of an active trading market may make it difficult to sell or obtain an accurate price for a 
security. If market conditions or issuer specific developments make it difficult to value securities, 
the Fund may value these securities using more subjective methods, such as fair value pricing. In such 
cases, the value determined for a security could be different than the value realized upon such security's 
sale. As a result, an investor could pay more than the market value when buying shares or receive less 
than the market value when selling shares. This could affect the proceeds of any redemption or the number 
of shares an investor receives upon purchase. The Fund is subject to the risk that it could not meet 
redemption requests within the allowable time period without significant dilution of remaining investors' 
interests in the Fund. To meet redemption requests or to raise cash to pursue other investment opportunities, 
the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions, 
which may adversely affect the Fund&#x2019;s performance. These risks are heightened for fixed-income instruments 
in a changing interest rate environment.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

      id="ixv-162591">After-tax returns are 
calculated using the highest individual federal marginal income tax rates in effect at the time of each 
distribution or capital gain or upon the sale of Fund shares, and do not reflect the impact of state
