What is the meaning of Rebate?

Negotiated return of a portion of the interest earned by the lender of stock to a short seller. When a stock is sold short, the seller borrows stock from an owner or custodian and delivers it to the buyer. The proceeds are delivered to the lender. The borrower, who is short, often wants a' Rebate' of the interest earned on the proceeds under the lender's control, especially when the stock can be borrowed from many sources. Note: The seller must pay the lender any dividends paid out or, in the case of bonds, interest that accrues daily during the term of the loan.
