2 years after the entry of the order for relief; or 1 year after the appointment or election of the first trustee under section 702, 1104, 1163, 1202, or 1302 of this title if such appointment or such election occurs before the expiration of the period specified in subparagraph (A); or the time the case is closed or dismissed. permits perfection of an interest in property to be effective against an entity that acquires rights in such property before the date of perfection; or provides for the maintenance or continuation of perfection of an interest in property to be effective against an entity that acquires rights in such property before the date on which action is taken to effect such maintenance or continuation. a law described in paragraph (1) requires seizure of such property or commencement of an action to accomplish such perfection, or maintenance or continuation of perfection of an interest in property; and such property has not been seized or such an action has not been commenced before the date of the filing of the petition; not later than 45 days after the date of receipt of such goods by the debtor; or not later than 20 days after the date of commencement of the case, if the 45-day period expires after the commencement of the case. If a seller of goods fails to provide notice in the manner described in paragraph (1), the seller still may assert the rights contained in section 503(b)(9). such producer or fisherman may not reclaim any grain or fish unless such producer or fisherman demands, in writing, reclamation of such grain or fish before ten days after receipt thereof by the debtor; and the court may deny reclamation to such a producer or fisherman with a right of reclamation that has made such a demand only if the court secures such claim by a lien. Notwithstanding sections 544, 545, 547, 548(a)(1)(B), and 548(b) of this title, the trustee may not avoid a transfer that is a margin payment, as defined in section 101, 741, or 761 of this title, or settlement payment, as defined in section 101 or 741 of this title, made by or to (or for the benefit of) a commodity broker, forward contract merchant, stockbroker, financial institution, financial participant, or securities clearing agency, or that is a transfer made by or to (or for the benefit of) a commodity broker, forward contract merchant, stockbroker, financial institution, financial participant, or securities clearing agency, in connection with a securities contract, as defined in section 741(7), commodity contract, as defined in section 761(4), or forward contract, that is made before the commencement of the case, except under section 548(a)(1)(A) of this title . Notwithstanding sections 544, 545, 547, 548(a)(1)(B), and 548(b) of this title, the trustee may not avoid a transfer made by or to (or for the benefit of) a repo participant or financial participant, in connection with a repurchase agreement and that is made before the commencement of the case, except under section 548(a)(1)(A) of this title . Notwithstanding sections 544, 545, 547, 548(a)(1)(B) and 548(b) of this title, the trustee may not avoid a transfer, made by or to (or for the benefit of) a swap participant or financial participant, under or in connection with any swap agreement and that is made before the commencement of the case, except under section 548(a)(1)(A) of this title . Notwithstanding the rights and powers of a trustee under sections 544(a), 545, 547, 549, and 553, if the court determines on a motion by the trustee made not later than 120 days after the date of the order for relief in a case under chapter 11 of this title and after notice and a hearing, that a return is in the best interests of the estate, the debtor, with the consent of a creditor and subject to the prior rights of holders of security interests in such goods or the proceeds of such goods, may return goods shipped to the debtor by the creditor before the commencement of the case, and the creditor may offset the purchase price of such goods against any claim of the creditor against the debtor that arose before the commencement of the case. Notwithstanding paragraphs (2) and (3) of section 545, the trustee may not avoid a warehouseman’s lien for storage, transportation, or other costs incidental to the storage and handling of goods. The prohibition under paragraph (1) shall be applied in a manner consistent with any State statute applicable to such lien that is similar to section 7–209 of the Uniform Commercial Code, as in effect on the date of enactment of the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005, or any successor to such section 7–209. Notwithstanding sections 544, 545, 547, 548(a)(1)(B), and 548(b) the trustee may not avoid a transfer made by or to (or for the benefit of) a master netting agreement participant under or in connection with any master netting agreement or any individual contract covered thereby that is made before the commencement of the case, except under section 548(a)(1)(A) and except to the extent that the trustee could otherwise avoid such a transfer made under an individual contract covered by such master netting agreement.
