1.150-1 (c) Definition of issue --

(1) In general.

Except as otherwise provided in this paragraph (c), the term issue means two or more bonds that meet all of the following requirements:

(i) Sold at substantially the same time.

The bonds are sold at substantially the same time. Bonds are treated as sold at substantially the same time if they are sold less than 15 days apart.

(ii) Sold pursuant to the same plan financing.

The bonds are sold pursuant to the same plan of financing. Factors material to the plan of financing include the purposes for the bonds and the structure of the financing. For example, generally --

(A) Bonds to finance a single facility or related facilities are part of the same plan of financing;

(B) Short-term bonds to finance working capital expenditures and long-term bonds to finance capital projects are not part of the same plan of financing; and

(C) Certificates of participation in a lease and general obligation bonds secured by tax revenues are not part of the same plan of financing.

(iii) Payable from same source of funds.

The bonds are reasonably expected to be paid from substantially the same source of funds, determined without regard to guarantees from parties unrelated to the obligor.

(2) Exception for taxable bonds.

Taxable bonds and tax-exempt bonds are not part of the same issue under this paragraph (c). The issuance of tax-exempt bonds in a transaction (or series of related transactions) that includes taxable bonds, however, may constitute an abusive arbitrage device under section 1.148-10(a) or a device to avoid other limitations in sections 103 and 141 through 150 (for example, structures involving windows or unreasonable allocations of bonds).

(3) Exception for certain bonds financing separate purposes --

(i) In general.

Bonds may be treated as part of separate issues if the requirements of this paragraph (c)(3) are satisfied. Each of these separate issues must finance a separate purpose (e.g., refunding a separate prior issue, financing a separate purpose investment, financing integrated or functionally related capital projects, and financing any clearly discrete governmental purpose). Each of these separate issues independently must be a tax-exempt bond (e.g., a governmental bond or a qualified mortgage bond). The aggregate proceeds, investments, and bonds in such a transaction must be allocated between each of the separate issues using a reasonable, consistently applied allocation method. If any separate issue consists of refunding bonds, the allocation rules in section 1.148-9(h) must be satisfied. An allocation is not reasonable if it achieves more favorable results under sections 103 and 141 to 150 than could be achieved with actual separate issues. All allocations under this paragraph (c)(3) must be made in writing on or before the issue date.

(ii) Exceptions.

This paragraph (c)(3) does not apply for purposes of sections 141(b)(5), 141(c)(1), 141(d)(1), 144(a), 148, 149(d), and 149(g).

(4) Special rules for certain financings --

(i) Draw-down loans.

Bonds issued pursuant to a draw-down loan are treated as part of a single issue. The issue date of that issue is the first date on which the aggregate draws under the loan exceed the lesser of $50,000 or 5 percent of the issue price.

(ii) Commercial paper --

(A) In general.

Short-term bonds having a maturity of 270 days or less (COMMERCIAL PAPER) issued pursuant to the same commercial paper program may be treated as part of a single issue, the issue date of which is the first date the aggregate amount of commercial paper issued under the program exceeds the lesser of $50,000 or 5 percent of the aggregate issue price of the commercial paper in the program. A commercial paper program is a program to issue commercial paper to finance or refinance the same governmental purpose pursuant to a single master legal document. Commercial paper is not part of the same commercial paper program unless issued during an 18-month period, beginning on the deemed issue date. In addition, commercial paper issued after the end of this 18-month period may be treated as part of the program to the extent issued to refund commercial paper that is part of the program, but only to the extent that --

(1) There is no increase in the principal amount outstanding; and

(2) The program does not have a term in excess of --

(i) 30 years; or

(ii) The period reasonably necessary for the governmental purposes of the program.

(B) Safe harbor.

The requirement of paragraph (c)(4)(ii)(A)(2) of this section is treated as satisfied if the weighted average maturity of the issue does not exceed 120 percent of the weighted average expected economic life of the property financed by the issue.

(iii) Certain general obligation bonds.

Except as otherwise provided in paragraph (c)(2) of this section, bonds that are secured by a pledge of the issuer’s full faith and credit (or a substantially similar pledge) and sold and issued on the same dates pursuant to a single offering document may be treated as part of the same issue if the issuer so elects on or before the issue date.

(5) Anti-abuse rule.

In order to prevent the avoidance of sections 103 and 141 through 150 and the general purposes thereof, the Commissioner may treat bonds as part of the same issue or as part of separate issues to clearly reflect the economic substance of a transaction.

(6) Sale date.

The sale date of a bond is the first day on which there is a binding contract in writing for the sale or exchange of the bond.
