Repurchase Agreements

Each of the Funds may enter into repurchase agreements. Repurchase agreements are primarily used by the Funds as short-term investments for cash positions. Under a repurchase agreement, a Fund purchases one or more debt securities and simultaneously agrees to sell those securities back to the seller at a mutually agreed-upon future price and date, normally one day or a few days later. The resale price is greater than the purchase price, reflecting an agreed-upon market interest rate during the purchaser’s holding period. While the maturities of the underlying securities in repurchase transactions may be more than one year, the term of each repurchase agreement will always be less than one year. The Funds follow certain procedures designed to minimize the risks inherent in such agreements. These procedures include effecting repurchase transactions generally with major global financial institutions whose creditworthiness is monitored by the Advisor. In addition, the value of the collateral underlying the repurchase agreement is required to be at least equal to the repurchase price, including any accrued interest income earned on the repurchase agreement. The Funds may invest in repurchase agreements through joint account arrangements; in such cases, each Fund holds a pro rata share of the collateral and interest income based upon the dollar amount of the repurchase agreements entered into by each Fund. The collateral underlying the repurchase agreement is held by the Fund’s custodian. A repurchase agreement is subject to the risk that the counterparty to the repurchase agreement that sells the securities may default on its obligation to repurchase them. In this circumstance, a Fund may lose money because it may not be able to sell the securities at the agreed upon time and price, the securities may lose value before they can be sold, the selling institution may declare bankruptcy or the Fund may have difficulty exercising rights to the collateral. During periods of high demand for repurchase agreements, the Funds may be unable to invest available cash in these instruments to the extent desired by the Advisor.

On August 31, 2021, the Funds had interest in joint repurchase agreements with the following counterparties, for the time periods and rates indicated. Amounts shown in the table below represent Principal Amount, Cost and Value for each respective repurchase agreement.
