then the taxpayer shall treat all amounts includible in gross income with respect to the qualified craft as income from sources within the United States for each taxable year ending after commencement of the lease. If this section applies to income with respect to a craft, it applies to all such amounts that are includible in the taxpayer's gross income, whether or not includible during or after the period of a lease to a United States person. Amounts derived by the taxpayer with respect to the qualified craft include any gain from the sale, exchange, or other disposition of the qualified craft. If this section applies to income with respect to a craft and there is a loss with respect to that craft (either due to the allowance of expenses and other deductions or due to a sale, exchange, or other disposition of the qualified craft), such loss is treated as allocable or apportionable to sources within the United States. The fact that a craft ceases to be section 38 property, ceases to be leased by the taxpayer to a United States person, or is leased or subleased for any period of time to a person who is not a United States person will not terminate the application of this section.
then this section will apply to the income with respect to the craft includible in the gross income of the transferee or distributee. This paragraph (e)(1) applies even though the transferor or distributor recognizes an amount of gain that increases basis in the hands of the transferee or distributee and even though the transferee or distributee is a nonresident alien or foreign corporation. For example, if a corporation distributes a craft the income of which is subject to this section to its parent corporation in a complete liquidation described in section 332(b), the parent corporation will be treated as if it satisfied the requirements of paragraph (a) of this section with respect to such craft if the basis of the property in the hands of the parent corporation is determined under section 334(b) (relating to the general rule on carryover of basis in liquidations). In further illustration, if a corporation distributes a craft the income of which is subject to this section, in a distribution to which section 301(a) applies, the distributee will be treated as if it satisfied the requirements of paragraph (a) of this section with respect to such craft if its basis is determined under section 301(d)(2) (relating to basis of corporate distributees) even though the basis may be the fair market value of the craft under section 301(d)(2)(A).
