Active Management Risk
The Fund’s overall allocation to subadvisers is actively managed and certain subadvisers also provide active management and as a result, the Fund’s performance will reflect in part the adviser’s or subadvisers’ ability to make investment decisions that are suited to achieving the Fund’s investment objective. To the extent it is actively managed, the Fund could under-perform other mutual funds with similar investment objectives.

Passive Management Risk
Because portions of the Fund are managed to seek investment results that track, before fees and expenses, those of the S&P SmallCap 600® Index, the Fund faces a risk of poor performance if:
  •  
The S&P SmallCap 600® Index declines generally or performs poorly relative to other indexes or individual stocks.
  •  
The stocks of companies which comprise the S&P SmallCap 600® Index fall out of favor with investors.
  •  
An adverse company specific event, such as an unfavorable earnings report, negatively affects the stock price of one of the larger companies in the S&P SmallCap 600® Index.
In addition, the performance of the portion of the Fund and the index may differ due to factors such as the use of representative sampling, the fees and expenses of the Fund, transaction costs, and the use of a tax‑managed strategy in seeking to track the index.
Multi Manager Risk [Member]

Risk [Text Block]
Multi-Manager Risk
Because each subadviser makes investment decisions independently, it is possible that the security selection process of the subadvisers may not complement one another. As a result, the Fund’s exposure to a given security, industry sector or market capitalization could be smaller or larger than would be the case if the Fund were managed by a single subadviser. It is possible that one or more of the subadvisers may, at any time, take positions that may be opposite of positions taken by other subadvisers. In such cases, the Fund will incur brokerage and other transaction costs, without accomplishing any net investment results. Subadvisers also may be competing with one another for similar positions at the same time, which could have the result of increasing a security’s cost. As a general proposition, a multi-manager approach increases the Fund’s portfolio turnover rate over the portfolio turnover rate of a single manager fund which may result in higher levels of realized capital gains or losses with respect to the Fund’s portfolio securities, higher brokerage commissions and other transaction costs. The subadvisers selected may under-perform the market generally or other subadvisers that could have been selected for the Fund.
Equity Securities Risk [Member]

Equity Securities Risk
Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response.
Small and Medium Sized Company Risk [Member]

Risk [Text Block]
Small- and Medium‑Sized Company Risk
Stocks of small- and medium‑sized companies may lack the management expertise, financial resources, product diversification, and competitive strengths of larger companies. Prices of such stocks may be subject to more abrupt or erratic movements than stock prices of larger, more established companies or the market averages in general. In addition, the frequency and volume of their trading may be less than is typical of larger companies, making them subject to wider price fluctuations. In some cases, there could be difficulties in selling the stocks of small- and medium‑sized companies at the desired time and price.
Tax Managed Investment Risk [Member]

Tax‑Managed Investment Risk
Market conditions may limit the Fund’s ability to generate tax losses or to generate dividend income taxed at favorable rates. Use of a tax‑managed strategy for a portion of the Fund’s assets may affect the investment decisions made for the Fund. For example, the Fund’s tax‑managed strategy may cause the Fund to hold a security in order to achieve more favorable tax treatment or to sell a security in order to create tax losses. The Fund’s ability to utilize various tax‑management techniques may be curtailed or eliminated in the future by tax legislation or regulation. Although a smaller portion of the Fund’s total return may consist of taxable distributions to shareholders as compared to non‑tax managed funds, there can be no assurance about the size of taxable distributions to shareholders. The performance of the Fund may deviate from that of non‑tax managed funds and may not provide as high a return before consideration of U.S. federal income tax consequences as non‑tax managed funds. Although a tax‑managed strategy is used with respect to a portion of the Fund’s assets, the Fund can realize capital gains.
Investment Style Risks [Member]

Investment Style Risks:
  •  
Value Investing Risk
To the extent a Fund subadviser employs a value style strategy, that portion of the Fund’s assets is subject to the possibility that value stocks may fall out of favor or perform poorly relative to other types of investments. With value investing, there is the risk that the market will not recognize that the securities selected are undervalued and they might not appreciate in value in the way the subadviser anticipates.
  •  
Growth Investing Risk
To the extent a Fund subadviser employs a growth style strategy, that portion of the Fund’s assets is subject to the possibility that these stocks can have relatively high valuations. Because of these high valuations, an investment in a growth stock can be more risky than an investment in a company with more modest growth expectations. Growth investing does not guarantee a profit or eliminate risk.
Preferred Securities Risk [Member]  
Prospectus [Line Items]

Preferred Securities Risk
Preferred securities may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.
Micro Sized Company Risk [Member]

Micro‑Sized Company Risk
The Fund is also subject to the general risk that the stocks of micro‑sized companies can involve greater risks than those associated with larger, more established companies. Micro‑sized company stocks may be subject to more abrupt or erratic price movements due to a number of reasons, including that the stocks are traded in lower
volume and that the issuers are more sensitive to changing conditions and have less certain growth prospects. Also, there are fewer market makers for these stocks and wider spreads between quoted bid and ask prices in the over‑the‑counter market for these stocks. Micro‑sized stocks tend to be less liquid, particularly during periods of market disruption. There normally is less publicly available information concerning these securities. Micro‑sized companies in which the Fund may invest typically have limited product lines, markets or financial resources or may be dependent on a small management group.
Convertible Securities Risk [Member]

Convertible Securities Risk
Convertible securities may be subordinate to other securities. In part, the total return for a convertible security depends upon performance of the underlying stock into which it can be converted. Also, issuers of convertible securities are often rated below investment grade or are not rated, are generally subject to a high degree of credit risk, are more likely to encounter financial difficulties and typically are more vulnerable to changes in the economy, such as a recession or a sustained period of rising interest rates, which could affect their ability to make interest and principal payments. If an issuer stops making interest and/or principal payments, the Fund could lose its entire investment.
Exchange Traded Fund ETF and Underlying Investment Company Risk [Member]

Risk [Text Block]
Exchange-Traded Fund (“ETF”) and Underlying Investment Company Risk
The risks of owning an ETF or other investment company generally reflect the risks of owning the underlying securities they are designed to track, although lack of liquidity in an ETF or investment company could result in its value being more volatile than the underlying portfolio of securities. Disruptions in the markets for the securities underlying ETFs and underlying investment companies purchased or sold by the Fund could result in losses on the Fund’s investment. ETFs and other investment companies also have management fees that increase their costs versus the costs of owning the underlying securities directly.
Market Risks [Member]

Market Risk
The price of equity securities may fluctuate, sometimes rapidly and unpredictably. Market risk may impact individual securities based on general market or economic conditions and/or real or perceived factors affecting specific industries or individual company fundamentals. These factors may include corporate earnings outlooks, changes in interest rates, investor sentiment, or industry competitive conditions. Additionally, events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions, the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also have a significant impact. Equity markets tend to be cyclical, with periods when prices generally rise and periods when prices generally decline, and are also generally more volatile than fixed income markets.
