CY2017	us-gaap	Immaterial Error Correction ImmaterialErrorCorrection	Although the Swiss Plan originated in prior years, the Company accounted for the Swiss Plan in accordance with ASC 715-30 Defined Benefit Plans - Pensions starting in 2017. The Company evaluated the impact of not recording the net pension obligation in the Consolidated Balance Sheets and corresponding charges in net income and total comprehensive income in the Consolidated Statements of Income and Comprehensive Income in the historical periods presented, and concluded that the effect was immaterial. The Company corrected the immaterial error in 2017 by recording an out of period expense of $1.5 million reflected in net income, an increase in the pension obligation of $4.7 million, an increase in deferred income tax assets of $0.7 million, and a decrease to accumulated other comprehensive income of $2.4 million.

CY2017	us-gaap	Objectives For Using Derivative Instruments ObjectivesForUsingDerivativeInstruments	The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. 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.

CY2017	us-gaap	Valuation Allowance Methodologies And Assumptions ValuationAllowanceMethodologiesAndAssumptions	The Company assessed whether a valuation allowance should be recorded against all of its deferred tax assets (“DTAs”) based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether DTAs will be realized are, (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carryforwards. In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. The Company evaluated its DTAs each reporting period, including an assessment of the cumulative income or loss over the most recent three-year period, to determine if a valuation allowance was required. A significant negative factor in the assessment was the Company’s three-year cumulative loss history as of January 25, 2015 and January 26, 2014 in Canada and the U.S. After a review of the four sources of taxable income described above and in view of its three-year cumulative losses, the Company was not able to conclude that it is more likely than not that its DTAs in Canada and the U.S. at January 25, 2015 and January 26, 2014 will be realized.
