PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” 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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 53% of the average value of its portfolio.

Example:

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. For each share class offered, the Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and annual Fund operating expenses remain the same for each share class. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

• To achieve its goal, the Fund normally invests at least 80% of its total assets in a diversified portfolio of high yield fixed income securities. These include corporate bonds, convertible securities and preferred securities. The Investment Manager will generally purchase securities for the Fund that are not investment grade (“junk” bonds), meaning securities with a rating of “BB” or lower as rated by Standard & Poor’s or a comparable rating by another nationally recognized rating agency. The Fund may also invest in debt securities that have not been rated by one of the major rating agencies, so long as the Fund’s Investment Manager has determined that the security is of comparable credit quality to similar rated securities.

• In managing its portfolio, the Fund’s Investment Manager concentrates on sector analysis, industry allocation and securities selection, deciding which types of bonds and industries to emphasize at a given time, and then which individual bonds to buy. The Fund attempts to anticipate shifts in the business cycle in determining types of bonds and industry sectors to target. In choosing individual securities, the Fund seeks out securities that appear to be undervalued within the emphasized industry sector. Companies that meet or exceed specific criteria established by the Manager in the selection process are purchased. Securities are sold when they reach internally determined pricing targets or no longer qualify under the Manager’s investment criteria.

• The Fund may, from time to time, take temporary defensive positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, or other conditions. When the Fund takes a defensive position, the Fund’s assets will be held in cash and/or cash equivalents.

• The Fund will not invest in Excluded Securities. Excluded Securities are securities issued by any company that is involved in the production or wholesale distribution of alcohol, tobacco, or gambling equipment, gambling enterprises, or which is involved, either directly or indirectly, in abortion or pornography, or promoting anti-family entertainment or alternative lifestyles.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You may lose money by investing in the Fund. Below are the main risks of investing in the Fund.

1. General Risk | As with most other mutual funds, you can lose money by investing in this Fund. Share prices fluctuate from day to day, and when you sell your shares, they may be worth less than you paid for them.

2. High Yield Security Risk | Investments in fixed-income securities that are rated below investment grade (“high yield securities”) by one or more Nationally Recognized Statistical Rating Organizations (NRSROs) may be subject to greater risk of loss of principal and interest than investments in higher-rated fixed-income securities. High yield securities are also generally considered to be subject to greater market risk than higher-rated securities. The capacity of issuers of high yield securities to pay interest and repay principal is more likely to weaken than is that of issuers of higher-rated securities in times of deteriorating economic conditions or rising interest rates. In addition, high yield securities may be more susceptible to real or perceived adverse economic conditions than higher-rated securities. The market for high yield securities may be less liquid than the market for higher-rated securities. This can adversely affect the Fund’s ability to buy or sell optimal quantities of high yield securities at desired prices.

3. Interest Rate Risk | When interest rates rise, bond prices fall; the higher the Fund’s duration (a calculation reflecting time risk, taking into account both the average maturity of the Fund’s portfolio and its average coupon return), the more sensitive the Fund is to interest rate risk. Currently, interest rates are at historical lows. A change in the economic environment that causes interest rates to rise back to more historically “normal” levels could have a pronounced negative effect on the Fund.

4. Credit Risk | High Yield securities (“junk” bonds) are subject to greater risk of loss than investment grade securities. The degree of risk for a particular security may not be reflected in its credit rating, and high yield securities may be particularly subject to this risk. Bonds rated, at the time of purchase, BB or lower by Standard & Poor’s (“junk” bonds) or, unrated, but determined to be of comparable quality by the Investment Manager, are subject to greater market risk and credit risk, or loss of principal and interest, than higher-rated securities.

5. Sector Risk | If certain industry sectors or types of securities don’t perform as well as the Fund expects, the Fund’s performance could suffer.

6. Excluded Security Risk | Because the Fund does not invest in Excluded Securities, and will divest itself of securities that are subsequently discovered to be ineligible, the Fund may be riskier that other Funds that invest in a broader array of securities.

Who Should Buy

This Fund The Fund is most appropriate for investors who want a high level of current income and are willing to accept a significant degree of volatility and risk.
