The date shown for securities represents the date when principal payments must be paid, taking into account any call options exercised by the issuer and any permissible maturity shortening features other than interest rate resets.

Legend

 (a) Yield represents either the annualized yield at the date of purchase, or the stated coupon rate, or, for floating and adjustable rate securities, the rate at period end.

 (b) Security or a portion of the security was sold in a reverse repurchase transaction and pledged for the benefit of the counterparty, J.P. Morgan Securities, LLC, as collateral to secure the future obligations of the Fund to repurchase the securities at an agreed-upon date and price within 7 days of period end. At period end, the value of securities pledged by the Fund for reverse repurchase transactions was $39,984,271 and the principal amount of obligations of the Fund with respect to reverse repurchase transactions was $40,000,000.

 (c) Coupon rates for floating and adjustable rate securities reflect the rates in effect at period end.

 (d) Coupon is indexed to a floating interest rate which may be multiplied by a specified factor and/or subject to caps or floors.

 (e) Security or a portion of the security purchased on a delayed delivery or when-issued basis.

 (f) Represents a forward settling transaction and therefore no collateral securities had been allocated as of period end. The agreement contemplated the delivery of U.S. Treasury Obligations as collateral on settlement date.

Investment Valuation

All investments are categorized as Level 2 under the Fair Value Hierarchy. The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities. Additional information on valuation inputs is provided later in this section.

Security transactions are accounted for as of trade date. The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels: Level 1 - quoted prices in active markets for identical investments: Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds etc.): Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available).

As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates fair value. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity. Securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market.
