CPA Exam Business Law: Agency, Bankruptcy, Secured Transactions

Last updated: May 2, 2026

Business Law: Agency, Bankruptcy, Secured Transactions questions are one of the highest-leverage areas to study for the CPA Exam. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Under UCC Article 9, a secured creditor's rights against third parties depend on attachment plus perfection. Attachment requires (1) value given, (2) the debtor having rights in the collateral, and (3) a security agreement authenticated by the debtor (or the secured party taking possession/control). Perfection — usually by filing a UCC-1 financing statement in the debtor's state of location — establishes priority, which generally follows the 'first to file or perfect' rule. A purchase-money security interest (PMSI) in goods receives a superpriority that beats earlier-perfected interests if the PMSI is properly perfected on time: for non-inventory goods, within 20 days after the debtor receives possession; for inventory, perfected before delivery and with proper authenticated notice to existing inventory secured parties.

Elements breakdown

Attachment

The moment the security interest becomes enforceable against the debtor.

  • Secured party gives value
  • Debtor has rights in collateral
  • Authenticated security agreement or possession/control

Perfection Methods

Steps that make the security interest effective against most third parties.

  • File UCC-1 in debtor's state of location
  • Take possession of tangible collateral
  • Take control of deposit accounts and investment property
  • Automatic perfection for PMSI in consumer goods
  • Notation on certificate of title for vehicles

General Priority Rule

Ranking among competing perfected interests in the same collateral.

  • First to file or perfect wins
  • Perfected beats unperfected
  • Among unperfected, first to attach wins
  • Buyer in ordinary course takes free of seller-created security interest
  • Future advances relate back to original filing date

PMSI Superpriority — Non-Inventory

Special priority for sellers/lenders financing the acquisition of equipment or other non-inventory goods.

  • PMSI must secure the price or enabling loan
  • Perfect within 20 days of debtor's possession
  • Beats prior perfected security interests in same collateral
  • Applies to equipment, fixtures, software embedded

PMSI Superpriority — Inventory

Stricter rules apply because inventory turns rapidly and existing lenders rely on it.

  • Perfect before debtor receives possession
  • Send authenticated notice to prior perfected secured parties
  • Notice must describe the inventory
  • Notice effective for five years
  • Failure on either step destroys superpriority

Buyer-in-Ordinary-Course Doctrine (BIOC)

A buyer purchasing inventory from a seller in the seller's ordinary business takes free of the seller's secured creditor.

  • Buyer in good faith
  • Without knowledge of violation
  • Buys from a person selling goods of that kind
  • Even if buyer knows of the security interest generally

Common patterns and traps

The Missed-20-Day-Window Trap

The exam gives a PMSI in equipment that perfects on day 21, day 25, or 'a month later.' Candidates focus on the fact that the lender called it a PMSI and conclude it gets superpriority. The grace period is a hard deadline measured from the debtor's possession of the collateral, not from the security agreement date or the invoice date. Late perfection collapses the PMSI back to ordinary first-to-file priority.

An answer choice that says the PMSI lender prevails because 'it is a PMSI in equipment' without checking the perfection date against the delivery date.

The Inventory-Notice Omission

For PMSI in inventory, candidates remember the 'perfect before delivery' part but forget the authenticated notice to prior perfected inventory lenders. Both steps are mandatory; either failure destroys the superpriority. The exam will give a fact pattern where the new lender files early but never sends notice, or sends notice but files after delivery.

A choice claiming the inventory PMSI lender beats the floor-plan financer based on 'early filing' alone, ignoring whether notice was sent.

The BIOC Override

Even a perfected secured party loses to a buyer in ordinary course of business who buys inventory from a merchant. Candidates pick the secured party because perfection 'beats everyone,' missing that BIOC is the major exception. The buyer's knowledge of the security interest's existence does not defeat BIOC — only knowledge that the sale violates the security agreement does.

An answer choice that gives priority to the bank over a retail customer because the bank perfected first, ignoring the customer's BIOC status.

The Attachment-Without-Perfection Confusion

Candidates conflate attachment with perfection. A security interest can be enforceable against the debtor (attached) yet lose to a later perfected creditor or a lien creditor (unperfected). The exam tests this by giving a signed security agreement but no filing, then introducing a competing creditor who files.

A choice that says the first secured party wins because 'the security agreement was signed first,' without addressing whether the interest was perfected.

The Wrong-State Filing Trap

UCC-1 filings must be made in the state where the debtor is 'located' — for a registered organization, that is its state of incorporation, not where its assets sit. Candidates assume filing happens where the equipment is, where the principal office is, or where the lender is located.

A fact pattern where the lender files in the state where the collateral is physically used, but the debtor is incorporated elsewhere — and the choice treats the filing as effective.

How it works

Picture Reyes Manufacturing, Inc. The bank holds a perfected blanket lien on 'all equipment, now owned or hereafter acquired,' filed in 2022. In Year 3, Liu Industries Co. sells Reyes a $180,000 CNC milling machine on credit, retaining a security interest to secure the unpaid price. Liu's interest is a PMSI in non-inventory goods (equipment). If Liu files its UCC-1 within 20 days after Reyes takes delivery of the milling machine, Liu's PMSI beats the bank — even though the bank filed first and the after-acquired clause technically reaches the new machine. Miss the 20-day window by a single day, and Liu drops behind the bank under the ordinary first-to-file rule. The result flips entirely on a calendar deadline, which is exactly the kind of detail the exam loves to test.

Worked examples

Worked Example 1

Which creditor has priority in the milling machine?

  • A Northbridge Bank, because its UCC-1 was filed first and the after-acquired property clause reaches the machine.
  • B Liu Industries, because its security interest is a PMSI in equipment and it perfected within 20 days after Reyes took possession. ✓ Correct
  • C Northbridge Bank, because Liu failed to send authenticated notice of its PMSI to Northbridge before delivery.
  • D Liu Industries, because a seller retaining a security interest in the goods sold automatically has priority over all other creditors regardless of filing.

Why B is correct: Liu holds a PMSI in non-inventory goods (equipment used in Reyes's manufacturing business). Under UCC §9-324(a), a non-inventory PMSI has superpriority over a conflicting earlier-perfected security interest in the same collateral if the PMSI is perfected when the debtor receives possession or within 20 days thereafter. Reyes took delivery March 10; Liu filed March 28 — 18 days later — so the PMSI is timely perfected and beats Northbridge's blanket equipment lien.

Why each wrong choice fails:

  • A: This applies the general first-to-file rule but ignores the PMSI superpriority exception in §9-324(a). The after-acquired clause reaches the machine, but the timely PMSI overrides Northbridge's earlier filing. (The Missed-20-Day-Window Trap)
  • C: The pre-delivery authenticated notice requirement applies only to PMSI in inventory under §9-324(b). For equipment (non-inventory), no notice is required — only timely perfection within 20 days. (The Inventory-Notice Omission)
  • D: There is no automatic-priority rule for sellers of goods. A PMSI must be properly perfected to gain superpriority; without timely perfection, the seller's interest is just an ordinary security interest subject to the first-to-file rule.
Worked Example 2

Which statement correctly describes Pinecrest's priority in the branded apparel relative to Hawthorne?

  • A Pinecrest has superpriority because it filed its UCC-1 before Bayside took possession of the apparel.
  • B Pinecrest has superpriority because its security interest is a purchase-money security interest in goods sold on credit.
  • C Pinecrest does not have superpriority because, although it perfected before delivery, it failed to send authenticated notice of its PMSI to Hawthorne before delivery. ✓ Correct
  • D Pinecrest does not have superpriority because PMSI superpriority is unavailable for inventory under UCC Article 9.

Why C is correct: Under UCC §9-324(b), a PMSI in inventory has superpriority only if (1) the PMSI is perfected when the debtor receives possession of the inventory AND (2) the PMSI holder sends an authenticated notification to the holder of any conflicting earlier-perfected security interest, received within five years before the debtor takes possession. Pinecrest satisfied the first requirement by filing February 5 (before the February 12 delivery) but failed the second by never notifying Hawthorne. Both steps are mandatory; Pinecrest drops to ordinary first-to-file priority and loses to Hawthorne.

Why each wrong choice fails:

  • A: Pre-delivery filing is necessary but not sufficient for inventory PMSI superpriority. The authenticated notice requirement is an independent and equally mandatory step under §9-324(b). (The Inventory-Notice Omission)
  • B: Being a PMSI is a threshold characterization, not automatic superpriority. Inventory PMSIs face stricter perfection requirements than non-inventory PMSIs, and skipping notice forfeits the superpriority entirely. (The Inventory-Notice Omission)
  • D: PMSI superpriority is available for inventory under §9-324(b); the rules are simply more demanding than for equipment. The category exists — Pinecrest just failed to satisfy it.
Worked Example 3

Is Coastal Trust Bank entitled to recover the refrigerator or its value from Diane?

  • A Yes, because Coastal Trust's security interest was perfected before Diane's purchase and the first-to-file rule controls.
  • B Yes, because Diane had actual knowledge of Coastal Trust's security interest at the time of purchase, defeating any buyer-in-ordinary-course protection.
  • C No, because Diane is a buyer in ordinary course of business under UCC §9-320(a) and takes free of Coastal Trust's security interest even though she knew of its existence. ✓ Correct
  • D No, because a security interest in consumer goods is automatically extinguished upon a retail sale regardless of the buyer's status.

Why C is correct: Under UCC §9-320(a), a buyer in ordinary course of business — defined in §1-201(b)(9) as a person who in good faith and without knowledge that the sale violates the rights of another buys from a person in the business of selling goods of that kind — takes free of a security interest created by the buyer's seller, even if perfected and even if the buyer knows of the security interest's existence. Diane purchased a refrigerator from a retail appliance store in the ordinary course; mere knowledge that Coastal Trust held a security interest does not defeat BIOC status. Only knowledge that the particular sale violates the security agreement defeats BIOC, and there is no such fact here.

Why each wrong choice fails:

  • A: The first-to-file rule governs priority among competing secured creditors and lien creditors, but BIOC is a statutory exception that overrides perfection in favor of ordinary retail buyers. Otherwise, no consumer could safely buy from a financed merchant. (The BIOC Override)
  • B: This misstates the BIOC knowledge standard. The buyer must lack knowledge that the sale itself violates the security agreement, not knowledge of the security interest's mere existence. A posted notice of the lien is not enough to defeat BIOC. (The BIOC Override)
  • D: There is no automatic extinguishment rule for consumer-goods sales. Diane prevails because of her BIOC status under §9-320(a), not because of any blanket consumer-protection cutoff. The reasoning is wrong even though the result is right.

Memory aid

VAR-FPC: attachment needs Value, Agreement (or possession), Rights — then choose Filing, Possession, or Control to perfect. PMSI timing: 'Equipment 20, Inventory before & notify.'

Key distinction

Non-inventory PMSI gets a 20-day grace period to perfect AFTER the debtor takes possession. Inventory PMSI must be perfected BEFORE delivery AND requires written notice to existing inventory lenders — there is no grace period and no shortcut.

Summary

Article 9 priority is mechanical: attach, perfect, and time the PMSI correctly — equipment within 20 days after delivery, inventory before delivery with notice — or the earlier blanket lender wins.
