(c) Definition of issue—
(1) In general.
Except as otherwise provided, the provisions of this paragraph (c) apply for all purposes of sections 103 and 141 through 150. Except as otherwise provided in this paragraph (c), two or more bonds are treated as part of the same issue if all of the following factors are present:
(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. For this purpose only, a variable yield bond is treated as sold on its issue date.
(ii) Sold pursuant to the same plan of 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.
(c)
(4)
Bonds are part of the same issue if 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.
(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.
