The Portfolio pays transaction costs, such as commissions, when it buys or sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Portfolio Operating Expenses or in the Examples, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 25% of the average value of its portfolio.

The Examples are intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Examples assume that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Examples also assume that your investment has a 5% return each year and that the Portfolio’s operating expenses stay the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

rr_StrategyNarrativeTextBlock |
As a matter of fundamental policy, the Portfolio, under normal circumstances, invests at least 80% of its net assets in municipal securities. For purposes of this policy, net assets include any borrowings for investment purposes. The Portfolio invests no more than 25% of its total assets in municipal securities of issuers located in any one state.
The municipal securities in which the Portfolio may invest are issued to raise money for a variety of public or private purposes, including general financing for state and local governments, the District of Columbia or possessions and territories of the United States, or financing for specific projects or public facilities. The interest paid on these securities is generally exempt from federal income tax, although in certain instances, it may be includable in income subject to alternative minimum tax.
The Portfolio invests at least 80% of its total assets in municipal securities rated A or better by national rating agencies (or, if unrated, determined by AllianceBernstein L.P., the Portfolio’s investment manager (the “Manager”), to be of comparable quality) and comparably rated municipal notes. The Portfolio may invest up to 20% of its total assets in fixed-income securities rated BB or B by national rating agencies, which are not investment-grade (commonly known as “junk bonds”).
The Portfolio may invest, without limit, in revenue bonds, which generally do not have the pledge of the credit of the issuer. The Portfolio may invest, without limit, in securities or obligations that are related in such a way that business or political developments or changes affecting one such security could also affect the others (for example, securities with interest that is paid from projects of a similar type).
The Portfolio may also invest up to 20% of its net assets in fixed-income securities of U.S. issuers that are not municipal securities if, in the Manager’s opinion, these securities will enhance the after-tax return for Portfolio investors.
The Portfolio may use derivatives, such as options, futures contracts, forward contracts and swaps.
In managing the Portfolio, the Manager may use interest rate forecasting to estimate the best level of interest rate risk at a given time.
The Portfolio seeks to maintain an effective duration of three and one-half years to seven years under normal market conditions. Duration is a measure that relates the expected price volatility of a security to changes in interest rates. The duration of a debt security is the weighted average term to maturity, expressed in years, of the present value of all future cash flows, including coupon payments and principal repayments.
Within the range described above, the Manager may moderately shorten the average duration of the Portfolio when it expects interest rates to rise and moderately lengthen average duration when it anticipates that interest rates will fall.
The Manager selects securities for purchase or sale based on its assessment of the securities’ risk and return characteristics as well as the securities’ impact on the overall risk and return characteristics of the Portfolio. In making this assessment, the Manager takes into account various factors including the credit quality and sensitivity to interest rates of the securities under consideration and of the Portfolio’s other holdings.

| Risk [Heading] |
rr_RiskHeading |
PRINCIPAL RISKS:
|
|
| Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
The share price of the Portfolio will fluctuate and you may lose money. There is no guarantee that the Portfolio will achieve its investment objective. - Interest Rate Risk: This is the risk that changes in interest rates will affect the value of the Portfolio’s investments in fixed-income debt securities such as bonds and notes. The Portfolio may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government policy initiatives and market reaction to those initiatives. Increases in interest rates may cause the value of the Portfolio’s investments to decline and this decrease in value may not be offset by higher income from new investments. The Portfolio will experience increased interest rate risk to the extent it invests in fixed-income securities with longer maturities or durations. A general rise in interest rates may cause investors to move out of fixed-income securities on a large scale, which could adversely affect the price and liquidity of fixed-income securities and could also result in increased redemptions from a Portfolio that invests largely in fixed-income securities.
- Credit Risk: This is the risk that the issuer or the guarantor of a debt security, or the counterparty to a derivatives or other contract, will be unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. The issuer or guarantor may default, potentially causing a loss of the full principal amount of a security and accrued interest. The degree of risk for a particular security may be reflected in its credit rating. The credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations. At times when credit risk is perceived to be greater, credit “spreads” (i.e., the difference between the yields on lower quality securities and the yields on higher quality securities) may get larger or “widen”. As a result, the values of the lower quality securities may go down more and they may become harder to sell and less liquid.
- Duration Risk: The duration of a fixed-income security may be shorter than or equal to full maturity of the fixed-income security. Fixed-income securities with longer durations have more interest rate risk and will decrease in price as interest rates rise. For example, a fixed-income security with a duration of three years would be expected to decrease in value by approximately 3% if interest rates increase by 1%. Securities that have final maturities longer than their durations may be affected by increased credit spreads to a far greater degree than their durations would suggest, because they are exposed to credit risk until final maturity.
- Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Portfolio’s investments in municipal securities. These factors include economic conditions, political or legislative changes, uncertainties related to the tax status of municipal securities, or the rights of investors in these securities. The value of municipal securities may also be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. In recent periods an increasing number of municipal issuers have defaulted on obligations, been downgraded or commenced insolvency proceedings. Financial difficulties of municipal issuers may continue or get worse. To the extent the Portfolio invests in a particular state’s municipal securities, it may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism and catastrophic natural disasters, such as hurricanes and earthquakes. The Portfolio’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, are subject to the risk that factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.
In addition, recent tax law changes could have a material impact on the value of municipal securities. Changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.
The Portfolio may invest in municipal securities of issuers in Puerto Rico or other U.S. territories and their governmental agencies and municipalities, which are exempt from federal, state, and, where applicable, local income taxes. These municipal securities may have more risks than those of other U.S. issuers of municipal securities. Like many U.S. states and municipalities, Puerto Rico experienced a significant downturn during the recent recession. Puerto Rico’s downturn was particularly severe, and Puerto Rico continues to face a very challenging economic and fiscal environment. If the general economic situation in Puerto Rico continues to persist or worsens, the volatility and credit quality of Puerto Rican municipal securities could continue to be adversely affected, and the market for such securities may deteriorate further.
- Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Portfolio’s assets can decline as can the value of the Portfolio’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.
- Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing the Portfolio from selling out of these illiquid or relatively less liquid securities at an advantageous price. Over recent years, regulatory changes have led to reduced liquidity in the marketplace, and the capacity of dealers to make markets in fixed-income securities has been outpaced by the growth in the size of the fixed-income markets. Liquidity risk may be magnified in a rising interest rate environment, where the value and liquidity of fixed-income securities generally go down. Derivatives and securities involving substantial market and credit risk tend to involve greater liquidity risk. The Portfolio is subject to more liquidity risk because the market for municipal securities is generally smaller than many other markets. Illiquid securities and relatively less liquid securities may also be difficult to value.
- Redemption Risk: The Portfolio may experience heavy redemptions that could cause the Portfolio to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline. Redemption risk is heightened during periods of overall market turmoil.
- Derivatives Risk: The Portfolio may use derivatives as direct investments to earn income, enhance return and broaden portfolio diversification, which entail greater risk than if used solely for hedging purposes. In addition to other risks such as the credit risk of the counterparty, derivatives involve the risk that changes in the value of the derivative may not correlate with relevant assets, rates or indices. Derivatives may be illiquid and difficult to price or unwind, and small changes may produce disproportionate losses for the Portfolio. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Assets required to be set aside or posted to cover or secure derivatives positions may themselves go down in value, and these collateral and other requirements may limit investment flexibility. Some derivatives involve leverage, which can make the Portfolio more volatile and can compound other risks. Use of derivatives may have different tax consequences for the Portfolio than an investment in the underlying security, and such differences may affect the amount, timing and character of income distributed to shareholders, including the proportion of income consisting of exempt-interest dividends. The U.S. Government and foreign governments are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin, reporting and registration requirements. The ultimate impact of the regulations remains unclear. Additional regulation may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance, or disrupt markets.
- Management Risk: The Portfolio is subject to management risk because it is an actively managed investment portfolio. The Manager will apply its investment techniques and risk analyses in making investment decisions for the Portfolio, but these techniques, analyses and decisions may not work as intended or may not produce the desired results. In some cases, derivatives and other investment techniques may be unavailable or the Manager may determine not to use them, possibly even under market conditions where their use could benefit the Portfolio. In addition, the Manager may change the Portfolio’s investment strategies or policies from time to time. Those changes may not lead to the results intended by the Manager and could have an adverse effect on the value or performance of the Portfolio.
- Market Risk: The Portfolio is subject to market risk, which is the risk that bond prices in general may decline over short or extended periods. In the past decade, financial markets in the United States and elsewhere have experienced increased volatility, decreased liquidity and heightened uncertainty. These market conditions may continue, worsen, or spread. The U.S. Government and the Federal Reserve, as well as certain foreign governments and central banks, have taken steps to support financial markets, including by keeping interest rates low. The Federal Reserve has reduced its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or decreases, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Portfolio invests.
In addition, policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.
- Tax Risk: There is no guarantee that the income on the Portfolio’s municipal securities will be exempt from regular federal income, and if applicable, state income taxes. Unfavorable legislation, adverse interpretations by federal or state authorities, litigation or noncompliant conduct by the issuer of a municipal security could affect the tax-exempt status of municipal securities. If the Internal Revenue Service or a state authority determines that an issuer of a municipal security has not complied with applicable requirements, interest from the security could become subject to regular federal income tax and/or state personal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly, and a portion of the distributions to Portfolio shareholders could be recharacterized as taxable. The U.S. Congress has considered changes to U.S. federal tax law that would, if enacted, have a negative impact on certain types of municipal securities, such as private activity bonds, or would otherwise make investments in municipal bonds less attractive.
- Lower-rated Securities Risk: Lower-rated securities, or junk bonds/high-yield securities, are subject to greater risk of loss of principal and interest and greater market risk than higher-rated securities. The capacity of issuers of lower-rated 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.
- Prepayment and Extension Risk: Prepayment risk is the risk that a loan, bond or other security might be called or otherwise converted, prepaid or redeemed before maturity. If this happens, particularly during a time of declining interest rates or credit spreads, the Portfolio will not benefit from the rise in market price that normally accompanies a decline in interest rates, and may not be able to invest the proceeds in securities providing as much income, resulting in a lower yield to the Portfolio. Conversely, extension risk is the risk that as interest rates rise or spreads widen, payments of securities may occur more slowly than anticipated by the market. If this happens, the values of these securities may go down because their interest rates are lower than current market rates and they remain outstanding longer than anticipated.
