In other news, a press release entitled, "Fitch: EU's Proposed LVNAV MMFs Could Face Concentration Risks" says, "A new money market fund structure, proposed as a compromise between constant and variable net asset value funds, may face challenges in maintaining high diversification due to the growing scarcity of high-quality short-term investments, Fitch Ratings says. This could make it harder for these funds to achieve and maintain 'AAAmmf' ratings than for other MMF structures. The new class of MMFs, low-volatility net asset value (LVNAV), has been proposed by the European Parliament's Committee on Economic and Monetary Affairs and will be put to the full parliament at end-April. It allows an MMF to issue and redeem units at a constant net asset value (CNAV) as long as this is within 20bp of its actual NAV, based on the amortised cost accounting approach for assets maturing within 90 days. All other assets must be valued using market or model prices."
