However, a taxpayer may apply §§ 1.1503(d)-1 through 1.1503(d)-7, in their entirety, to dual consolidated losses incurred in taxable years beginning on or after January 1, 2007, by filing its return and attaching to such return the domestic use agreements, certifications, or other information in accordance with these regulations. For purposes of this section, the term application date means either April 18, 2007, or, if the taxpayer applies these regulations pursuant to the preceding sentence, January 1, 2007.
