but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value.
B. Short Sales: Short sales are the sales of securities that the fund does not own. The fund sells a security it does not own in anticipation of a decline in the value of that security. In order to deliver the security to the purchaser, the fund borrows the security from a broker-dealer. The fund must segregate, as collateral for its obligation to return the borrowed security, an amount of cash and long security positions at least equal to the market value of the security sold short. In the absence of a default, the collateral segregated by the fund cannot be repledged, resold or rehypothecated. This results in the fund holding a significant portion of its assets in cash. The fund later closes out the position by returning the security to the lender, typically by purchasing the security in the open market. Long security positions segregated as collateral are shown in the Schedule of Investments.
C. Various inputs may be used to determine the value of the fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.
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 used to determine the fair value of investments). Any investments valued with significant unobservable inputs are noted on the Schedule of Investments.
At March 31, 2021, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.
