If the properties exchanged under section 1031 are part of a group of assets which constitute a trade or business under section 1060, the like-kind property and other property or money which are treated as transferred in exchange for the like-kind property shall be excluded from the allocation rules of section 1060. However, section 1060 shall apply to property which is not like-kind property or other property or money which is treated as transferred in exchange for the like-kind property. For application of the section 1060 allocation rules to property which is not part of the like-kind exchange, see § 1.1060-1(b), (c), and (d) Example 1 in § 1.338-6(b), to which reference is made by § 1.1060-1(c)(2).
