rr_RiskNarrativeTextBlock

• Interest Rate Changes. Interest rate increases can cause the price of a money market security to decrease.
• Foreign Exposure. Entities located in foreign countries can be affected by adverse political, regulatory, market, or economic developments in those countries.
• Financial Services Exposure. Changes in government regulation and interest rates and economic downturns can have a significant negative effect on issuers in the financial services sector, including the price of their securities or their ability to meet their payment obligations.
• Issuer-Specific Changes. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a money market security to decrease.

Portfolio Turnover

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 operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

• Normally investing in obligations of the U.S. Government, its agencies or instrumentalities, obligations fully guaranteed by the U.S. Government, or obligations of the State of North Carolina, bonds and notes of any North Carolina local government or public authority, and high-grade money market instruments, as permitted pursuant to North Carolina General Statute 159-30, as amended (the Statute) and 20 North Carolina Administrative Code 3.0703, as amended (the Code).
• Investing in securities rated in the three highest categories by at least one nationally recognized rating service, or, if unrated, determined to be of equivalent quality.
• Managing the fund to have similar overall interest rate risk to the Barclays^® U.S. 3-6 Month Treasury Bill Index.
• Allocating assets across different market sectors and maturities.
• Investing more than 25% of total assets in the financial services industries.
• Analyzing the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.

Principal Investment Risks

• Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.
• Foreign Exposure. Entities located in foreign countries can be affected by adverse political, regulatory, market, or economic developments in those countries.
• Financial Services Exposure. Changes in government regulation and interest rates and economic downturns can have a significant negative effect on issuers in the financial services sector, including the price of their securities or their ability to meet their payment obligations.
• Prepayment. The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.
• Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. You could lose money by investing in the fund.

Performance

The following information is intended to help you understand the risks of investing in the fund. The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index over various periods of time. The index description appears in the Additional Information about the Index section of the prospectus. Prior to November 1, 2010, the fund operated under certain different investment policies and, prior to August 1, 2011, compared its performance to a different benchmark. The fund's historical performance may not represent its current investment policies. Past performance is not an indication of future performance.
