In general. Even though a notice of a lien imposed by section 6321 is filed in accordance with § 301.6323(f)-1, the lien is not valid with respect to a security interest which:

Comes into existence after the tax lien filing,

Is in qualified property covered by the terms of a commercial transactions financing agreement entered into before the tax lien filing, and

Is protected under local law against a judgment lien arising, as of the time of the tax lien filing, out of an unsecured obligation.

Commercial transactions financing agreement. For purposes of this section, the term “commercial transactions financing agreement” means a written agreement entered into by a person in the course of his trade or business—

To make loans to the taxpayer (whether or not at the option of the person agreeing to make such loans) to be secured by commercial financing security acquired by the taxpayer in the ordinary course of his trade or business, or

To purchase commercial financing security, other than inventory, acquired by the taxpayer in the ordinary course of his trade or business.

Commercial financing security—(1) In general. The term “commercial financing security” means—

Paper of a kind ordinarily arising in commercial transactions.

Accounts receivable (as defined in subparagraph (2) of this paragraph (c)),

Mortgages on real property, and

Inventory.

Definitions. For purposes of §§ 301.6323(d)-1, 301.6323(h)-1 and this section—

A contract right is any right to payment under a contract not yet earned by performance and not evidenced by an instrument or chattel paper, and

An account receivable is any right to payment for goods sold or leased or for services rendered which is not evidenced by an instrument or chattel paper.

Qualified property. For purposes of paragraph (a) of this section, qualified property consists solely of commercial financing security acquired by the taxpayer-debtor before the 46th day after the date of tax lien filing: Commercial financing security acquired before such day may be qualified property even though it is acquired by the taxpayer after the lender received actual notice or knowledge of the filing of the tax lien. For example, although the receipt of actual notice or knowledge of the filing of the notice of the tax lien has the effect of ending the period within which protected disbursements may be made to the taxpayer, property which is acquired by the taxpayer after the lender receives actual notice or knowledge of such filing and before such 46th day, which otherwise qualifies as commercial financing security, becomes commercial financing security to which the priority of the lender extends for loans made before he received the actual notice or knowledge. An account receivable (as defined in paragraph (c)(2)(ii) of this section) is acquired by a taxpayer at the time, and to the extent, a right to payment is earned by performance. Chattel paper, documents of title, negotiable instruments, securities, and mortgages on real estate are acquired by a taxpayer when he obtains rights in the paper or mortgage. Inventory is acquired by the taxpayer when title passes to him. A contract right (as defined in paragraph (c)(2)(i) of this section) is acquired by a taxpayer when the contract is made. Identifiable proceeds, which arise from the collection or disposition of qualified property by the taxpayer, are considered to be acquired at the time such qualified property is acquired if the secured party has a continuously perfected security interest in the proceeds under local law. The term “proceeds” includes whatever is received when collateral is sold, exchanged, or collected. For purposes of this paragraph, the term “identifiable proceeds” does not include money, checks and the like which have been commingled with other cash proceeds. Property acquired by the taxpayer after the 45th day following tax lien filing, by the expenditure of proceeds, is not qualified property.

Purchaser treated as acquiring security interest. A person who purchases commercial financing security, other than inventory, pursuant to a commercial transactions financing agreement is treated, for purposes of this section, as having acquired a security interest in the commercial financing security. In the case of a bona fide purchase at a discount, a purchaser of commercial financing security who satisfies the requirements of this section has priority over the tax lien to the full extent of the security.

Examples. The provisions of this section may be illustrated by the following examples:

On June 1, 1970, a tax is assessed against M, a tool manufacturer, with respect to his delinquent tax liability. On June 15, 1970, M enters into a written financing agreement with X, a bank. The agreement provides that, in consideration of such sums as X may advance to M, X is to have a security interest in all of M's presently owned and subsequently acquired commercial paper, accounts receivable, and inventory (including inventory in the manufacturing stages and raw materials). On July 6, 1970, notice of the tax lien is filed in accordance with § 301.6323(f)-1. On August 3, 1970, without actual notice or knowledge of the tax lien filing, X advances $10,000 to M. On August 5, 1970, M acquires additional inventory through the purchase of raw materials. On August 20, 1970, M has accounts receivable, arising from the sale of tools, amounting to $5,000. Under local law, X's security interest arising by reason of the $10,000 advance on August 3, 1970, has priority, with respect to the raw materials and accounts receivable, over a judgment lien against M arising July 6, 1970 (the date of tax lien filing) out of an unsecured obligation.

Because the $10,000 advance was made before the 46th day after the tax lien filing, and the accounts receivable in the amount of $5,000 and the raw materials were acquired by M before such 46th day, X's $10,000 security interest in the accounts receivable and the inventory has priority over the tax lien. The priority of X's security interest also extends to the proceeds, received on or after the 46th day after the tax lien filing, from the liquidation of the accounts receivable and inventory held by M on August 20, 1970, if X has a continuously perfected security interest in identifiable proceeds under local law. However, the priority of X's security interest will not extend to other property acquired with such proceeds.

Assume the same facts as in example 1 except that on July 15, 1970, X has actual knowledge of the tax lien filing. Because an agreement does not qualify as a commercial transactions financing agreement when a disbursement is made after tax lien filing with actual knowledge of the filing, X's security interest will not have priority over the tax lien with respect to the $10,000 advance made on August 3, 1970.

Assume the same facts as in example 1 except that, instead of additional inventory, on August 5, 1970, M acquires an account receivable as the result of the sale of machinery which M no longer needs in his business. Even though the account receivable was acquired by taxpayer M before the 46th day after tax lien filing, the tax lien will have priority over X's security interest arising in the account receivable pursuant to the earlier written agreement because the account receivable was not acquired by the taxpayer in the ordinary course of his trade or business.

Pursuant to a written agreement with the N Manufacturing Company entered into on January 4, 1971, Y a commercial factor, purchases the accounts receivable arising out of N's regular sales to its customers. On November 1, 1971, in accordance with § 301.6323(f)-1, a notice of lien is filed with respect to N's delinquent tax liability. On December 6, 1971, Y, without actual notice or knowledge of the tax lien filing, purchases all of the accounts receivable resulting from N's November 1971 sales. Y has taken appropriate steps under local law so that the December 6, 1971, purchase is protected against a judgment lien arising November 1, 1971 (the date of tax lien filing) out of an unsecured obligation. Because the purchaser of commercial financing security, other than inventory, is treated as having acquired a security interest in commercial financing security, and because Y otherwise meets the requirements of this section, the tax lien is not valid with respect to Y's December 6, 1971, purchase of N's accounts receivable.
