Granting rehypothecation or "use rights" with respect to pledged collateral is common in the over-the-counter derivative market. In fact, subject to the pledgor's consent, the credit support annex to the International Swaps and Derivatives Association master agreement provides the secured party with the right to rehypothecate, or use for its own purposes, collateral pledged to it---subject only to the obligation to return the collateral once the pledgor has satisfied its obligations. Customers, however, are often alarmed to learn that the dealer requires such an unrestricted right to use and sell the pledged collateral.
