Under the PPSA security interests continue in collateral upon transfers of collateral if the transfer gives rise to proceeds1, unless the secured party has expressly or impliedly consented to the transfer, or the security interest is extinguished for the benefit of a buyer or lessee under one of the ten (10) extinguishment rules (discussed next).
The PPSA expressly validates the right of a secured party to follow collateral into the hands of a buyer or lessee if a security interest over transferred collateral is not extinguished by the transfer. This was a very difficult area of law before commencement of the PPSA. See Chapter 14 (Following collateral and value) for discussion.
