|
| Portfolio Turnover [Text Block] |
rr_PortfolioTurnoverTextBlock |
The fund pays transaction-related costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).
A higher turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held
in a taxable account. These costs, which are not reflected in annual fund operating expenses or the above example, affect fund
performance. The fund’s turnover rate in the most recent fiscal year was 67%.

The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in
other funds. It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem
all your shares at the end of those periods. It assumes a 5% return on your investment each year and that the fund’s operating
expenses remain the same. Your actual costs may be higher or lower.

Investments
|
|
| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
We invest mainly in convertible securities of U.S. companies. Under normal circumstances, we invest at least 80% of the fund’s
net assets in convertible securities. This policy may be changed only after 60 days’ notice to shareholders. Convertible
securities combine the investment characteristics of bonds and common stocks. Convertible securities include bonds, preferred stocks
and other instruments that can be converted into or exchanged for common stock or equivalent value. A significant portion of the
convertible securities we buy are below-investment-grade (sometimes referred to as “junk bonds”). The convertible bonds
we buy usually have intermediate-to long-term stated maturities (three years or longer), but often contain “put” features,
which allow bondholders to sell the bond back to the company under specified circumstances, that result in shorter effective maturities.
When deciding whether to buy or sell investments, we may consider, among other factors: (i) a security’s structural features,
such as its position in a company’s capital structure and “put” and “call” features (a company’s
right to repurchase the security under specified circumstances is a “call” feature); (ii) credit and prepayment risks;
and (iii) with respect to a company’s common stock underlying a convertible security, the stock’s valuation and the
company’s financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows
and dividends.

Risks
|
|
| Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
It is important to understand that you can lose money by investing in the fund.
The value of convertible securities in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety
of reasons, including general financial market conditions, factors related to a specific company or industry, changing market perceptions
of the risk of default and changes in government intervention in the financial markets. These factors may also lead to increased
volatility and reduced liquidity in the markets for convertible securities. These risks are generally greater for convertible securities
issued by small and midsize companies (which may constitute a significant portion of the fund’s investments from time to
time). The value of convertible securities may be adversely affected by changes in the prices of underlying common stocks. Convertible
securities tend to provide higher yields than common stocks. However, a higher yield may not protect investors against the risk
of loss or adequately mitigate any loss associated with a decline in the price of a convertible security. Convertible securities
are subject to credit risk, which is the risk that an issuer of the fund’s investments may default on payment of
interest or principal. Credit risk is generally greater for below-investment-grade convertible securities (a significant part of
the fund’s investments). Generally, convertible securities may be less sensitive to interest rate changes than non-convertible
bonds as a result of convertible securities’ convertibility and “put” features. Interest rate risk is generally
greater for longer-term bonds and convertible securities whose underlying stock price has fallen significantly below the conversion
price.
The fund may not achieve its goal, and it is not intended to be a complete investment program. An investment in the fund is not insured
or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

performance of the fund’s class Y shares, which are not offered in this prospectus, and has not been adjusted to reflect
the lower fees associated with class I shares; had it, returns would have been higher. Please remember that past performance is
