Notes to portfolio of investments
Securities valuation
All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation under unusual or unexpected circumstances.
Debt securities are valued at the evaluated bid price provided by an independent pricing service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.
Investments in registered open-end investment companies (other than those listed on a foreign or domestic exchange or market) are valued at net asset value.
Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by Allspring Funds Management, LLC (“Allspring Funds Management”) [note: include full name if first occurrence], which was named the valuation designee by the Board of Trustees. As the valuation designee, Allspring Funds Management is responsible for day-to-day valuation activities for the Allspring Funds. In connection with these responsibilities, Allspring Funds Management has established a Valuation Committee and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities. On a quarterly basis, the Board of Trustees receives reports of valuation actions taken by the Valuation Committee. On at least an annual basis, the Board of Trustees receives an assessment of the adequacy and effectiveness of Allspring Funds Management’s process for determining the fair value of the portfolio of investments.
Foreign currency translation
The accounting records of the Fund are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Valuation Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.
When-issued transactions
The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.
Fair valuation measurements
Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:
•Level 1 – quoted prices in active markets for identical securities
•Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
•Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)
The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.
