# 1.103-11 Bonds held by substantial users.

(a) *In general.* Section 103(c) (4), (5), or (6) (relating respectively to interest on bonds to finance certain exempt facilities, interest on bonds to finance industrial parks, and the exemption for certain small issues of industrial development bonds) does not apply, as provided in section 103(c)(7), with respect to any obligation for any period during which such obligation is held either by a person who is a substantial user of the facilities with respect to which the proceeds of such obligation were used or by a related person (within the meaning of section 103(c)(6)(C) and paragraph (e) of § 1.103-10). Therefore, in such a case, interest paid on such an obligation is includable in the gross income of a substantial user (or related person) for any period during which such obligation is held by such user (or related person).

(b) *Substantial user.* In general, a substantial user of a facility includes any nonexempt person who regularly uses a part of such facility in his trade or business. However, unless a facility, or a part thereof, is constructed, reconstructed, or acquired specifically for a nonexempt person or persons, such a nonexempt person shall be considered to be a substantial user of a facility only if (1) the gross revenue derived by such user with respect to such facility is more than 5 percent of the total revenue derived by all users of such facility or (2) the amount of area of the facility occupied by such user is more than 5 percent of the entire usable area of the facility. Under certain facts and circumstances, where a nonexempt person has a contractual or preemptive right to the exclusive use of property or a portion of property, such person may be a substantial user of such property. A substantial user may also be a lessee or sublessee of all or any portion of the facility. A licensee or similar person may also be a substantial user where his use is regular and is not merely a casual, infrequent, or sporadic use of the facility. Absent special circumstances, individuals who are physically present on or in the facility as employees of a substantial user shall not be deemed to be substantial users.

(c) *Examples.* The application of section 103(c)(7) and this section are illustrated by the following examples:
