5 Collier on Bankruptcy P 547.05
Summary
The keystone of a preference is a transfer of an interest in the debtor’s property within 90 days (or one year, in the case of an insider) before the bankruptcy petition is filed. Section 547(e) turns the word “transfer” into a term of art. A transfer for purposes of section 547(b) is not necessarily made at the time when the debtor and the transferee effected a completed and irrevocable transfer as between themselves (and therefore may not have occurred outside of the lookback period). Under section 547(e), the time of the transfer may depend upon when the transaction was perfected against third parties.
Section 547(e)(2)1 provides that, for the purposes of section 547, a transfer is made—
