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 Portfolio may deviate from this calculation time under unusual or unexpected circumstances.
Equity securities and futures contracts that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.
Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally 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 the Board of Trustees. The Board of Trustees has established a Valuation Committee comprised of the Trustees 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, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.
Securities lending
The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. When securities are on loan, the Portfolio receives interest or dividends on those securities. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). Investments in Securities Lending Fund are valued at the evaluated bid price provided by an independent pricing service. The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the Investment Company Act of 1940 and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company. Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service.
In a securities lending transaction, the net asset value of the Portfolio is affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In such an event, the terms of the agreement allow the unaffiliated securities lending agent to use the collateral to purchase replacement securities on behalf of the Portfolio or pay the Portfolio the market value of the loaned securities. The Portfolio bears the risk of loss with respect to depreciation of its investment of the cash collateral.
Futures contracts
Futures contracts are agreements between the Portfolio and a counterparty to buy or sell a specific amount of a commodity, financial instrument or currency at a specified price and on a specified date. The Portfolio may buy and sell futures contracts in order to gain exposure to, or protect against, changes in security values and is subject to equity price risk. The primary risks associated with the use of futures contracts are the imperfect correlation between changes in market values of securities held by the Portfolio and the prices of futures contracts, and the possibility of an illiquid market. Futures contracts are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange. With futures contracts, there is minimal counterparty risk to the Portfolio since futures contracts are exchange traded and the exchange’s clearinghouse, as the counterparty to all exchange traded futures, guarantees the futures contracts against default.
Upon entering into a futures contracts, the Portfolio is required to deposit either cash or securities (initial margin) with the broker in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are paid to or from the broker each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains or

losses and, if any, shown as variation margin receivable (payable). Should the Portfolio fail to make requested variation margin payments, the broker can gain access to the initial margin to satisfy the Portfolio’s payment obligations. When the contracts are closed, a realized gain or loss is recorded.
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 Portfolio’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 Portfolio’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 Portfolio’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.
The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of February 28, 2021:
