The Company evaluated the impact of not recording the net pension obligation in the Balance Sheets and corresponding charges in net income and total comprehensive income in the Statements of Income and Statements of Comprehensive Income in the historical periods presented, and concluded that the effect was immaterial. The Company corrected the immaterial error in fiscal year 2017 by recording an out of period expense, computed as of February 1, 2016, resulting in a decrease of $1.4 million in net income, an increase in the pension obligation of $5.8 million, an increase in deferred income tax assets of $1.3 million, and a decrease to accumulated other comprehensive income of $3.1 million.

The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company uses derivative financial instruments in the form of forward contracts to mitigate risk associated with adverse movements in these foreign currency exchange rates on a portion of foreign denominated expenses expected to be realized during the current and following fiscal year.

CY2018	us-gaap	Valuation Allowance Methodologies And Assumptions ValuationAllowanceMethodologiesAndAssumptions	The valuation allowances established relate to all U. S. and state deferred tax assets, for which we have determined that it is more likely than not that a benefit will not be realized. In considering in whether a valuation allowance was required for our U.S. deferred income tax assets, we considered all available positive and negative evidence. Positive evidence considered included reversing taxable temporary differences. Negative evidence considered included the cumulative taxable losses in the U.S. recorded during the three year period ended January 29, 2018, on both an annual and cumulative basis. Based on the weight of all available evidence, we concluded that the negative evidence outweighed the positive evidence and that it was more likely than not that the U.S. federal and state deferred tax assets that cannot be realized through the reversal of taxable temporary differences would not be realized. As a result, we have established a full valuation allowance against the deferred tax assets in the U.S. that will not be realized through the reversal of taxable temporary differences.
