Valuation Inputs
The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.
• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)
• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.
The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.
