Income Taxes	Income Taxes The provision for income taxes for interim periods is based on an estimate of the annual effective tax rate adjusted to reflect the impact of discrete items. Management judgment is required in projecting ordinary income to estimate the Company’s annual effective tax rate. A provision for U.S. income tax has not been recorded on the temporary difference related to the Company’s foreign subsidiary. The Company has determined that this temporary difference is indefinitely reinvested outside of the U.S. The effective tax rate for the thirteen weeks ended October 28, 2017, was 38.5%, compared to 22.6% for the thirteen weeks ended October 29, 2016. The year-over year effective tax rate increase is primarily due to the release of approximately $1.6 million of certain income tax reserves as a result of the conclusion of an Internal Revenue Service audit in the prior-year period that did not recur in the current-year period. The effective tax rate for the thirty-nine weeks ended October 28, 2017, was (298.1)%, compared to 30.3% for the thirty-nine weeks ended October 29, 2016. The year-over year effective tax rate increase is primarily due to the relative impact of permanent and discrete items on the nominal pre-tax loss, including a tax shortfall from stock-based compensation.
