Excess elective deferrals shall be adjusted for any income or loss. For taxable years beginning on or after January 1, 2008, the income or loss allocable to excess elective deferrals allocated to each participant is the income or loss allocable to the participant's elective deferral account for the taxable year multiplied by a fraction, the numerator of which is such participant's excess elective deferrals for the year and the denominator is the participant's account balance attributable to elective deferrals without regard to any income or loss occurring during such taxable year. Effective solely for the taxable year beginning on or after January 1, 2007, and to the extent the excess elective deferrals were credited with gain or loss as of an accounting date within the gap period (i.e., the period after the close of the taxable year and prior to the distribution), allocable income or loss also includes 10% of the amount determined under the preceding sentence multiplied by the number of whole calendar months between the end of the participant’s taxable year and the date of distribution, counting the month of distribution if distribution occurred after the 15th of such month.
