Fitch Affirms Wells Fargo Advantage Municipal Cash Management Money Market Fund at 'AAAmmf'

CHICAGO--(BUSINESS WIRE)--Fitch Ratings has affirmed the 'AAAmmf' rating assigned to Wells Fargo Advantage Municipal Cash Management Money Market Fund, a tax exempt money market fund managed by Wells Fargo Funds Management, LLC (WFFM).

The affirmed rating reflects the fund's extremely strong capacity to achieve its investment objective of preserving capital and providing shareholder liquidity through limiting credit, market and liquidity risks. The main drivers of the affirmation are the credit quality, diversification, and liquidity of the portfolio assets and the capabilities and resources of WFFM as investment advisor. As of Aug. 15, 2011, the fund had approximately $3.1 billion in total assets under management.

The Wells Fargo Advantage Municipal Cash Management Fund seeks current income exempt from regular federal income tax, while preserving capital and liquidity. The fund pursues its investment objectives by investing in a portfolio of high-quality, short-term municipal obligations that are issued by or on behalf of states, territories and possessions of the U.S. or their political subdivisions and financing authorities. These investments may have fixed, floating, or variable rates of interest, and typically include variable rate demand notes (VRDNs) putable to a third party financial institution in seven days or less, or other municipal bonds/notes. Consistent with Fitch's 'AAAmmf' rating criteria, the fund maintains a high credit quality by investing exclusively in securities rated at least 'A/F1' or equivalent.

The fund seeks to limit interest rate exposure and spread risk by limiting its weighted average maturity to reset date (WAMr) and weighted average final maturity (WAMf) to 60 days and 120 days, respectively, consistent with Fitch's 'AAAmmf' rating criteria. As of Aug. 15, 2011 the fund had a WAMr of 11 days and a WAMf of 11 days.

The fund's additional investment restrictions are aimed at maintaining sufficient levels of daily and weekly liquidity to meet investors' redemption requests. In line with amended Rule 2a-7 under the Investment Company Act of 1940, which governs the investment activities and operations of U.S. money market funds, the fund must invest at least 30% of total assets in weekly liquid assets. As of Aug. 15, 2011, the fund met the liquidity requirements mandated by Rule 2a-7 and was also in line with the liquidity guidelines outlined in Fitch's rating criteria.

The rating may be sensitive to material changes in the credit quality or market risk profiles of the fund. A material adverse deviation from Fitch guidelines for any key rating driver could cause the rating to be lowered by Fitch.

WFFM, a wholly owned subsidiary of Wells Fargo & Company, manages the fund's investment operations. As of March, 2010, WFFM had more than $184 billion in assets and employed over 350 investment professionals. Wells Fargo & Company is headquartered in San Francisco and is the fourth largest bank in the U.S. by assets and deposits.
