Lance Armstrong, Inc. is a corporation that sells vitamins.  It got its startup money in 2010 by obtaining a loan from USPS Bank, which took a security interest in all of the debtor's inventory (including after-acquired).  USPS Bank perfected by filing a proper UCC-1.  On May 24, 2012, Lance Armstrong, Inc., being down to just 10 crates of vitamins (worth $100,000), purchased 60 crates of vitamins for $600,000.   At that time, they owed $800,000 on their loan to USPS Bank.  On July 2, 2012, Lance Armstrong, Inc. bought 20 more crates of vitamins for $200,000 cash. On August 23, 2012, Lance Armstrong, Inc. filed for Chapter 7 bankruptcy.  At that time, it still owed $800,000 on its loan. 

Assume that the fair market value of vitamins has remained steady for the past 6 months ($10,000 per crate). Also assume that Lance Armstrong, Inc. conducts no business on Fridays. Which of the following is true?

1. No matter how many crates of vitamins are in inventory on August 23, 2012, the bankruptcy trustee can set aside the security interest in $200,000 worth of the vitamins as a preference.

2. If there are 90 crates of vitamins on hand on August 23, 2012, then USPS Bank will have its entire $800,000 claim fully secured by the inventory.

3. If there are 75 crates on hand on August 23, 2012, then under section 547(c)(5), USPS Bank will have a secured claim of $600,000 and an unsecured claim of $200,000.

4. If there are only 35 crates of vitamins on hand on August 23, 2012, then the trustee cannot set aside the 20-crate purchase on July 2 as a preference.
