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 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 82% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund 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 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 that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Strategy [Heading]

Principal Investment Strategies:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund's Sub-Adviser seeks to achieve the Fund's investment objective by investing, under normal market conditions, in a diversified portfolio of (1) convertible, (2) equity (common and preferred stock) and (3) fixed-income securities of corporate issuers, including securities of foreign issuers and those rated below investment grade (rated BB+ or lower by S&P or comparably rated by another nationally recognized statistical rating organization (NRSRO)), also known as "high-yield" or "junk" bonds, and in unrated debt securities determined by the Sub-Adviser to be of comparable quality. Junk bonds, which may be purchased in any amount, are speculative investments that carry greater risks and are more susceptible to real or perceived adverse economic and competitive industry conditions than higher quality fixed-income securities. Convertible and fixed income securities are purchased without restriction as to maturity. In addition, the Fund may invest without restriction as to issuer capitalization or country. The Fund attempts to utilize these different types of securities to strike the appropriate balance between risk and reward in terms of growth and income when compared to a peer group of securities that the Sub-Adviser believes have similar risk of loss. In general, the Sub-Adviser buys a blend of equity and convertible securities offering the potential for long-term growth and current income and sells them when the issuer's economic fundamentals deteriorate or relative valuations between securities change. The Sub-Adviser purchases individual convertible and equity securities based on the potential to generate above-average income and/or capital growth appreciation. The Sub-Adviser buys fixed-income securities that it believes have a higher expected total return when compared to competing convertible or equity securities. Within the universe of fixed-income securities, the Sub-Adviser selects specific securities based upon their expected total return and expected probability of default when compared to a peer group of securities with similar credit risk. The Sub-Adviser sells them when the issuer's economic fundamentals deteriorate or relative valuations between securities change. The Fund's Sub-Adviser may engage in active and frequent trading of the Fund's portfolio securities to achieve the Fund's investment objective.

The Fund may also engage in securities lending.

Risk [Heading]

Principal Investment Risks:

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Although the Fund will strive to meet its investment objective, there is no assurance that it will do so. Many factors affect the Fund's net asset value and performance.

Call or Redemption Risk – If interest rates decline, issuers of debt securities may exercise redemption or call provisions. This may force the Fund to reinvest redemption or call proceeds in securities with lower yields, which may reduce Fund performance.

Changing Fixed Income Market Conditions Risk – During periods of sustained rising rates, fixed income risks will be amplified. If the U.S. Federal Reserve's Federal Open Market Committee ("FOMC") raises the federal funds interest rate target, interest rates across the U.S. financial system may rise. Rising rates tend to decrease liquidity, increase trading costs, and increase volatility, all of which make portfolio management more difficult and costly to the Fund and its shareholders.

Credit Risk – Issuers of debt securities may suffer from a reduced ability to repay their interest and principal obligations. They may even default on interest and/or principal payments due to the Fund. An increase in credit risk or a default will cause the value of Fund debt securities to decline. Issuers with lower credit quality are more susceptible to economic or industry downturns and are more likely to default.

Foreign Investing Risk – Investing in foreign companies, or ETFs which invest in foreign companies, may involve more risks than investing in U.S. companies. These risks can increase the potential for losses in the Fund and may include, among others, currency devaluations, currency risks (fluctuations in currency exchange rates), country risks (political, diplomatic, regional conflicts, terrorism, war, social and economic instability and policies that have the effect of limiting or restricting foreign investment or the movement of assets), different trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility. Additionally, investments in securities denominated in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. A decline in the value of foreign currencies relative to the U.S. dollar will reduce the value of securities held by the Fund and denominated in those currencies.

Interest Rate Risk – In general, the price of a debt security falls when interest rates rise. Debt securities have varying levels of sensitivity to changes in interest rates. Securities with longer maturities may be more sensitive to interest rate changes.

Liquidity Risk – Some securities may have few market-makers and low trading volume, which tend to increase transaction costs and may make it impossible for a Fund to dispose of a security position at all or at a price which represents current or fair market value.

Lower-Rated Securities Risk – Securities rated below investment-grade, sometimes called "high-yield" or "junk" bonds, are speculative investments that generally have more credit risk than higher-rated securities. Companies issuing high yield fixed-income securities are not as strong financially as those issuing securities with higher credit ratings and are more likely to encounter financial difficulties. Lower rated issuers are more likely to default and their securities could become worthless.

Management Risk – The Fund is subject to management risk because it is an actively managed investment portfolio. The Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its decisions will produce the intended result. The successful use of hedging and risk management techniques may be adversely affected by imperfect correlation between movements in the price of the hedging vehicles and the securities being hedged.

Portfolio Turnover Risk – A higher portfolio turnover will result in higher transactional and brokerage costs and may result in higher taxes when Fund shares are held in a taxable account.

Private Placement Risk – Privately issued securities, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended, are restricted securities that are not registered with the U.S. Securities and Exchange Commission ("SEC"). Accordingly, the liquidity of the market for specific privately issued securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Privately issued securities that the Sub-Adviser determines to be "illiquid' are subject to the Fund's policy of not investing more than 15% of its net assets in illiquid securities.

Securities Lending Risk – The risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Small and Medium Capitalization Risk – The Fund's investments in smaller and medium-sized companies carry more risks than investments in larger companies. Companies with small and medium size market capitalization often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies.

Stock Market Risk – Stock markets can be volatile. In other words, the prices of stocks can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions. The Fund's investments may decline in value if the stock markets perform poorly.
