Accounting Policies [Abstract]
Nature of Business and Basis of Presentation	1. Nature of Business and Basis of Presentation Nature of Business—Zumiez Inc., including its wholly-owned subsidiaries, (“Zumiez”, the “Company,” “we,” “us,” “its” and “our”) is a leading specialty retailer of apparel, footwear, accessories and hardgoods for young men and women who want to express their individuality through the fashion, music, art and culture of action sports, streetwear, and other unique lifestyles. At February 3, 2018, we operated 698 stores; 607 in the United States (“U.S.”), 50 in Canada, 34 in Europe and 7 in Australia. We operate under the names Zumiez, Blue Tomato and Fast Times. Additionally, we operate ecommerce websites at zumiez.com, blue-tomato.com and fasttimes.com.au. Fiscal Year—We use a fiscal calendar widely used by the retail industry that results in a fiscal year consisting of a 52- or 53-week period ending on the Saturday closest to January 31. Each fiscal year consists of four 13-week quarters, with an extra week added to the fourth quarter every five or six years. The fiscal year ended February 3, 2018 was a 53-week period. The fiscal years ended January 28, 2017 and January 30, 2016 were 52-week periods. Basis of Presentation—The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Zumiez Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. These estimates can also affect supplemental information disclosed by us, including information about contingencies, risk and financial condition. Actual results could differ from these estimates and assumptions.

Fair Value of Financial Instruments—We disclose the estimated fair value of our financial instruments. Financial instruments are generally defined as cash, evidence of ownership interest in an entity or a contractual obligation that both conveys to one entity a right to receive cash or other financial instruments from another entity and imposes on the other entity the obligation to deliver cash or other financial instruments to the first entity. Our financial instruments, other than those presented in Note 10, “Fair Value Measurements,” include cash and cash equivalents, receivables, payables and other liabilities. The carrying amounts of cash and cash equivalents, receivables, payables and other liabilities approximate fair value because of the short-term nature of these instruments. Our policy is to present transfers into and transfers out of hierarchy levels as of the actual date of the event or change in circumstances that caused the transfer.

Cash and Cash Equivalents—We consider all highly liquid investments with original maturity of three months or less when purchased to be cash equivalents.

Concentration of Risk—We maintain our cash and cash equivalents in accounts with major financial institutions in the form of demand deposits, money market accounts and state and local municipal securities. Deposits in these financial institutions may exceed the amount of federal deposit insurance provided on such deposits.

Marketable Securities—Our marketable securities primarily consist of state and local municipal securities and variable-rate demand notes. Variable-rate demand notes are considered highly liquid. Although the variable-rate demand notes have long-term nominal maturity dates, the interest rates generally reset weekly. Despite the long-term nature of the underlying securities of the variable-rate demand notes, we have the ability to quickly liquidate these securities, which have an embedded put option that allows the bondholder to sell the security at par plus accrued interest.

Investments are considered to be impaired when a decline in fair value is determined to be other-than-temporary. If the cost of an investment exceeds its fair value, we evaluate information about the underlying investment that is publicly available such as analyst reports, applicable industry data and other pertinent information and assess our intent and ability to hold the security. For fixed-income securities, we also evaluate whether we have plans to sell the security or it is more likely than not we will be required to sell the security before recovery. The investment would be written down to its fair value at the time the impairment is deemed to have occurred and a new cost basis is established. Future adverse changes in market conditions, poor operating results of underlying investments or other factors could result in losses that may not be reflected in an investment’s current carrying value, possibly requiring an impairment charge in the future.

Inventories—Merchandise inventories are valued at the lower of cost or net realizable value. The cost of merchandise inventories are based upon an average cost methodology. Merchandise inventories may include items that have been written down to our best estimate of their net realizable value. Our decisions to write-down our merchandise inventories are based on their current rate of sale, the age of the inventory, the profitability of the inventory and other factors. The inventory related to this reserve is not marked up in subsequent periods. The inventory reserve includes inventory whose net realizable value is below cost and an estimate for inventory shrinkage. Shrinkage refers to a reduction in inventory due to shoplifting, employee theft and other matters. We estimate an inventory shrinkage reserve for anticipated losses for the period. We have reserved for inventory at February 3, 2018 and January 28, 2017 in the amounts of $5.1 million and $4.8 million.

Fixed Assets—Fixed assets primarily consist of leasehold improvements, fixtures, land, buildings, computer equipment, software and store equipment. Fixed assets are stated at cost less accumulated depreciation utilizing the straight-line method over the assets’ estimated useful lives. The useful lives of our major classes of fixed assets are as follows:


Leasehold improvements	Lesser of 10 years or the term of the lease
Fixtures	3 to 7 years
Buildings, land and building and land improvements	15 to 39 years
Computer equipment, software, store equipment & other	3 to 5 years

The cost and related accumulated depreciation of assets sold or otherwise disposed of is removed from fixed assets and the related gain or loss is recorded in selling, general and administrative expenses on the consolidated statements of income.

Asset Retirement Obligations—An asset retirement obligation (“ARO”) represents a legal obligation associated with the retirement of a tangible long-lived asset that is incurred upon the acquisition, construction, development or normal operation of that long-lived asset. Our AROs are associated with leasehold improvements that, at the end of a lease, we are contractually obligated to remove in order to comply with certain lease agreements. The ARO balance at February 3, 2018 and January 28, 2017 is $2.8 million and $2.7 million and is recorded in other liabilities and other long-term liabilities on the consolidated balance sheets and will be subsequently adjusted for changes in fair value. The associated estimated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset and depreciated over its useful life.

Valuation of Long-Lived Assets—We review the carrying value of long-lived assets or asset groups (defined as a store, corporate facility or distribution center) for impairment when events or changes in circumstances indicate that the carrying values may not be recoverable. Recoverability of assets to be held and used is determined by a comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered impaired, the impairment recognized is measured by comparing the fair value of the assets or asset group to the carrying values. The estimation of future cash flows from operating activities requires significant judgments of factors that include forecasting future sales, gross profit and operating expenses. In addition to historical results, current trends and initiatives, long-term macro-economic and industry factors are qualitatively considered. Additionally, management seeks input from store operations related to local economic conditions. Impairment charges are included in selling, general and administrative expenses on the consolidated statements of income.

Goodwill—Goodwill represents the excess of purchase price over the fair value of acquired tangible and identifiable intangible net assets. We test goodwill for impairment on an annual basis or more frequently if indicators of impairment are present. We perform our annual impairment measurement test on the first day of the fourth quarter. Events that may trigger an early impairment review include significant changes in the current business climate, future expectations of economic conditions, declines in our operating results of our reporting units, or an expectation that the carrying amount may not be recoverable.

We have an option to test goodwill for impairment by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. If we choose not to perform the qualitative test or we determine that it is more likely than not that the fair value of the reporting unit is less than the carrying amount, we perform a quantitative two-step impairment test. The first step compares the carrying value of the reporting unit to its estimated fair value, which is based on the perspective of a market-participant. If the fair value of the reporting unit is lower than the carrying value, then a second step is performed to quantify the amount of the impairment. The second step includes estimating the fair value of the reporting unit by taking the net assets of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit’s goodwill is compared to the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, we recognize an impairment loss in an amount equal to the excess, not to exceed the carrying amount.

We generally determine the fair value of each of our reporting units based on a combination of the income approach and the market valuation approaches. Key assumptions in the income approach include estimating future cash flows, long-term growth rates and weighted average cost of capital. Our ability to realize the future cash flows used in our fair value calculations is affected by factors such as changes in economic conditions, operating performance and our business strategies. Key assumptions in the market approaches include identifying companies and transactions with comparable business factors, such as earnings growth, profitability, business and financial risk.

Intangible Assets—Our intangible assets consist of trade names and trademarks with indefinite lives and certain definite-lived intangible assets. We test our indefinite-lived intangible assets for impairment on an annual basis, or more frequently if indicators of impairment are present. We test our indefinite-lived assets by estimating the fair value of the asset and comparing that to the carrying value, an impairment loss is recorded for the amount that carrying value exceeds the estimated fair value. The fair value of the trade names and trademarks is determined using the relief from royalty method. This method assumes that the trade name and trademarks have value to the extent that their owner is relieved of the obligation to pay royalties for the benefits received from them. The assumptions used in this method requires management judgment and estimates in forecasting future revenue growth, discount rates, and royalty rates.

Definite-lived intangible assets, which consist of developed technology, customer relationships and non-complete agreements, are amortized using the straight-line method over their estimated useful lives. Additionally, we test the definite-lived intangible assets when facts and circumstances indicate that the carrying values may not be recoverable. We first assess the recoverability of our definite-lived intangible assets by comparing the undiscounted cash flows of the definite-lived asset less its carrying value. If the undiscounted cash flows are less than the carrying value, we then determine the estimated fair value of our definite-lived asset by taking the estimated future operating cash flows derived from the operation to which the asset relates over its remaining useful life, using a discounted cash flow analysis and comparing it to the carrying value. Any impairment would be measured as the difference between the carrying amount and the estimated fair value. Changes in any of these estimates, projections and assumptions could have a material effect of the fair value of these assets in future measurement periods and result in an impairment which could materially affect our results of operations.

Deferred Rent, Rent Expense and Tenant Allowances—We lease our stores and certain corporate and other operating facilities under operating leases. A majority of our leases provide for ongoing co-tenancy requirements or early cancellation clauses that would further lower rental rates, or permit lease terminations, or both, in the event that co-tenants cease to operate for specific periods or if certain sales levels are not met in specific periods. Most of the store leases require payment of a specified minimum rent and a contingent rent based on a percentage of the store’s net sales in excess of a specified threshold, as well as real estate taxes, insurance, common area maintenance charges and other executory costs. Most of the lease agreements have defined escalating rent provisions, which are straight-lined over the term of the related lease. We recognize rent expense over the term of the lease, plus the construction period prior to occupancy of the retail location. For certain locations, we receive tenant allowances and report these amounts as a liability, which is amortized as a reduction to rent expense over the term of the lease.

Claims and Contingencies—We are subject to various claims and contingencies related to lawsuits, insurance, regulatory and other matters arising out of the normal course of business. We accrue a liability if the likelihood of an adverse outcome is probable and the amount is estimable. If the likelihood of an adverse outcome is only reasonably possible (as opposed to probable), or if an estimate is not determinable, we provide disclosure of a material claim or contingency.

Revenue Recognition—Revenue is recognized upon purchase at our retail store locations. For our ecommerce sales, revenue is recognized upon delivery to the customer. Taxes collected from our customers are recorded on a net basis. We accrue for estimated sales returns by customers based on historical return experience. The allowance for sales returns at February 3, 2018 was $2.6 million and at January 28, 2017 was $2.2 million. We record the sale of gift cards as a current liability and recognize revenue when a customer redeems a gift card. Additionally, the portion of gift cards that will not be redeemed (“gift card breakage”) is recognized in net sales after 24 months, at which time the likelihood of redemption is considered remote based on our historical redemption patterns. For the fiscal years ended February 3, 2018, January 28, 2017 and January 30, 2016, we recorded net sales related to gift card breakage income of $1.1 million, $1.1 million and $0.9 million.

Loyalty Program—We have a customer loyalty program, the Zumiez STASH, which allows members to earn points for purchases or performance of certain activities. The points can be redeemed for a broad range of rewards, including product and experiential rewards. Points earned for purchases are recorded as a current liability and a reduction of net sales based on the fair value of the points at the time the points are earned and estimated redemption rates. The revenue is recognized upon redemption of points for rewards. Points earned for the performance of activities are recorded as a current liability based on the estimated cost of the points and as marketing expense when redeemed. During fiscal 2017, we recognized $3.8 million in revenue due to changes in the estimated redemption rate. The deferred revenue related to our customer loyalty program was $1.6 million at February 3, 2018 and $4.3 million at January 28, 2017.

Cost of Goods Sold—Cost of goods sold consists of branded merchandise costs and our private label merchandise costs including design, sourcing, importing and inbound freight costs. Our cost of goods sold also includes shrinkage, buying, occupancy, ecommerce fulfillment, distribution and warehousing costs (including associated depreciation) and freight costs for store merchandise transfers. Cash consideration received from vendors is reported as a reduction of cost of goods sold if the inventory has sold, a reduction of the carrying value of the inventory if the inventory is still on hand, or a reduction of selling, general and administrative expense if the amounts are reimbursements of specific, incremental and identifiable costs of selling the vendors’ products.

Shipping Revenue and Costs—We include shipping revenue related to ecommerce sales in net sales and the related freight cost is charged to cost of goods sold.

Selling, General and Administrative Expense—Selling, general and administrative expenses consist primarily of store personnel wages and benefits, administrative staff and infrastructure expenses, freight costs for merchandise shipments from the distribution centers to the stores, store supplies, depreciation on fixed assets at the home office and stores, facility expenses, training expenses and advertising and marketing costs. Credit card fees, insurance, public company expenses, legal expenses, amortization of intangibles assets and other miscellaneous operating costs are also included in selling, general and administrative expenses.

Advertising—We expense advertising costs as incurred, except for catalog costs, which are expensed once the catalog is mailed. Advertising expenses are net of sponsorships and vendor reimbursements. Advertising expense was $10.8 million, $10.0 million and $9.5 million for the fiscal years ended February 3, 2018, January 28, 2017 and January 30, 2016.

Stock-Based Compensation—We account for stock-based compensation by recording the estimated fair value of stock-based awards granted as compensation expense over the vesting period, net of estimated forfeitures. Stock-based compensation expense is attributed using the straight-line method. We estimate forfeitures of stock-based awards based on historical experience and expected future activity. The fair value of restricted stock awards and units is measured based on the closing price of our common stock on the date of grant. The fair value of stock option grants is estimated on the date of grant using the Black-Scholes option pricing model.

Common Stock Share Repurchases—We may repurchase shares of our common stock under authorizations made from time to time by our Board of Directors. Under applicable Washington State law, shares repurchased are retired and not presented separately as treasury stock on the consolidated financial statements. Instead, the value of repurchased shares is deducted from retained earnings.

Income Taxes—We use the asset and liability method of accounting for income taxes. Using this method, deferred tax assets and liabilities are recorded based on the differences between the financial reporting and tax basis of assets and liabilities. The deferred tax assets and liabilities are calculated using the enacted tax rates and laws that we expect to be in effect when the differences are expected to reverse. We routinely evaluate the likelihood of realizing the benefit of our deferred tax assets and may record a valuation allowance if, based on all available evidence, it is determined that it is more likely than not that all or some portion of the deferred tax benefit will not to be realized. The valuation allowance on our deferred tax assets was $3.6 million at February 3, 2017 and $0.1 million at January 28, 2017.

We regularly evaluate the likelihood of realizing the benefit of income tax positions that we have taken in various federal, state and foreign filings by considering all relevant facts, circumstances and information available. If we believe it is more likely than not that our position will be sustained, we recognize a benefit at the largest amount that we believe is cumulatively greater than 50% likely to be realized. Interest and penalties related to income tax matters are classified as a component of income tax expense. Unrecognized tax benefits are recorded in other long-term liabilities on the consolidated balance sheets.

Our tax provision for interim periods is determined using an estimate of our annual effective rate, adjusted for discrete items, if any, that are taken into account in the relevant period. As the fiscal year progresses, we periodically refine our estimate based on actual events and earnings by jurisdiction. This ongoing estimation process can result in changes to our expected effective tax rate for the full fiscal year. When this occurs, we adjust the income tax provision during the quarter in which the change in estimate occurs so that our year-to-date provision equals our expected annual rate.

Earnings per Share—Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on the weighted average number of common shares and common share equivalents outstanding during the period. The dilutive effect of stock options and restricted stock is applicable only in periods of net income. Common share equivalents included in the computation represent shares issuable upon assumed exercise of outstanding stock options, employee stock purchase plan funds held to acquire stock and non-vested restricted stock. Potentially anti-dilutive securities not included in the calculation of diluted earnings per share are options to purchase common stock where the option exercise price is greater than the average market price of our common stock during the period reported.

Foreign Currency Translation—Assets and liabilities denominated in foreign currencies are translated into U.S. dollars, the reporting currency, at the exchange rate prevailing at the balance sheet date. Revenue and expenses denominated in foreign currencies are translated into U.S. dollars at the monthly average exchange rate for the period and the translation adjustments are reported as an element of accumulated other comprehensive loss on the consolidated balance sheets.

Segment Reporting—We identify our operating segments according to how our business activities are managed and evaluated. Our operating segments have been aggregated and are reported as one reportable segment based on the similar nature of products sold, production, merchandising and distribution processes involved, target customers and economic characteristics.

Recent Accounting Standards—In March 2016, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) as part of its simplification initiative that includes multiple provisions intended to simplify various aspects of the accounting for share-based payments. Upon the adoption of the ASU, excess tax benefits and deficiencies for share-based payments are recorded as an adjustment of income taxes and reflected in operating cash flows rather than recorded in equity and reported in financing cash flows. The guidance allows for the employer to withhold up to the maximum statutory tax rates in the applicable jurisdictions without triggering liability accounting. The guidance also allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. We adopted this standard beginning January 29, 2017. The ASU related to accounting for excess tax benefits and deficiencies was adopted prospectively, resulting in recognition of excess tax deficiencies in income tax expense rather than additional paid-in capital of $0.5 million for the fiscal year ended February 3, 2018. The amendment related to operating cash flows was adopted retrospectively, resulting in an immaterial change to net cash provided by operations and net cash used in financing activities for the year ended January 28, 2017 and January 30, 2016.

In February 2016, the FASB issued a comprehensive standard related to lease accounting to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Most significantly, the new guidance requires lessees to recognize operating leases with a term of more than 12 months as lease assets and lease liabilities. The adoption will require a modified retrospective approach at the beginning of the earliest period presented. The new standard is effective for the fiscal year beginning after December 15, 2018. We are continuing to evaluate the impact of this standard. We expect this standard will have a material impact on our consolidated financial statements, primarily our consolidated balance sheets and related disclosures. Our current minimum lease commitments are disclosed in Note 9, “Commitments and Contingencies”.

In January 2016, the FASB issued a new standard related primarily to accounting for equity investments, financial liabilities where the fair value option has been elected, and the presentation and disclosure requirements for financial instruments. There will no longer be an available-for-sale classification and therefore, no changes in fair value will be reported in other comprehensive income for equity securities with readily determinable fair values. The new standard will be effective for the fiscal year beginning after December 15, 2017. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

In July 2015, the FASB issued guidance simplifying the measurement of inventory. This standard requires entities that use inventory methods other than the last-in, first-out (LIFO) or retail inventory method to measure inventory at the lower of cost or net realizable value, which is defined as the estimated selling prices in the normal course of business, less reasonably predictable costs of completion, disposal, and transportation. We adopted this guidance beginning January 29, 2017 and the adoption did not have a material impact on our consolidated financial statements.

In May 2014, the FASB issued a comprehensive new revenue recognition standard. The new standard allows for a full retrospective approach to transition or a modified retrospective approach. This guidance is effective for fiscal years beginning after December 15, 2017. We will adopt on February 4, 2018 using a modified retrospective approach. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Revolving Credit Facilities and Debt	8. Revolving Credit Facilities and Debt On February 5, 2016, the Company entered into an asset-based revolving credit agreement with Wells Fargo Bank, National Association, which provides for a senior secured revolving credit facility of up to $100 million (“ABL Facility”), subject to a borrowing base, with a letter of credit sub-limit of $10 million. The ABL Facility is available for working capital and other general corporate purposes. The ABL Facility will mature on February 5, 2021. The ABL Facility is secured by a first-priority security interest in substantially all of the personal property (but not the real property) of the Company. Amounts borrowed under the ABL Facility bear interest, at the Company’s option, at either an adjusted LIBOR rate plus a margin of 1.25% to 1.75% per annum, or an alternate base rate plus a margin of 0.25% to 0.75% per annum. The Company is also required to pay a fee of 0.25% per annum on undrawn commitments under the ABL Facility. Customary agency fees and letter of credit fees are also payable in respect of the ABL Facility. There were no borrowings outstanding under the ABL Facility at February 3, 2018 or January 28, 2017. We had no open commercial letters of credit outstanding under our secured revolving credit facility at February 3, 2018 or January 28, 2017. Additionally, we have revolving lines of credit with UniCredit Bank Austria of up to 20.5 million Euro ($25.6 million) at February 3, 2018, the proceeds of which are used to fund certain international operations. The revolving lines of credit bears interest at 1.65%. There was $0.9 million in borrowings outstanding under the revolving lines of credit at February 3, 2018 and no borrowing outstanding at January 28, 2017. There were no open commercial letters of credit outstanding under these revolving lines of credit at February 3, 2018 and January 28, 2017.

Purchase Commitments—At February 3, 2018 and January 28, 2017, we had outstanding purchase orders to acquire merchandise from vendors of $208.5 million and $168.8 million. We have an option to cancel these commitments with no notice prior to shipment, except for certain private label, packaging supplies and international purchase orders in which we are obligated to repay contractual amounts upon cancellation.

Litigation—We are involved from time to time in claims, proceedings and litigation arising in the ordinary course of business. We have made accruals with respect to these matters, where appropriate, which are reflected in our consolidated financial statements. For some matters, the amount of liability is not probable or the amount cannot be reasonably estimated and therefore accruals have not been made. We may enter into discussions regarding settlement of these matters, and may enter into settlement agreements, if we believe settlement is in the best interest of our shareholders.

A putative class action, Alexia Herrera, on behalf of herself and all other similarly situated, v. Zumiez Inc., was filed against us in the Eastern District Count of California, Sacramento Division under case number 2:16-cv-01802-SB in August 2016. Alexandra Bernal filed the initial complaint and then in October 2016 added Alexia Herrera as a named plaintiff and Alexandra Bernal left the case. The putative class action lawsuit against us alleges, among other things, various violations of California’s wage and hour laws, including alleged violations of failure to pay reporting time. In May 2017 we moved for judgment on the pleadings in that plaintiff’s cause of action for reporting-time pay should fail as a matter of law as the plaintiff and the other putative class members did not “report for work” with respect to certain shifts on which the plaintiff’s claims are based. In August 2017, the court denied the motion. However, in October 2017 the district court certified the order denying the motion for judgment on the pleadings for immediate interlocutory review by the United States Court of Appeals for the Ninth Circuit. We then filed a petition for permission to appeal the order denying the motion for judgment on the pleadings with the United States Court of Appeals for the Ninth Circuit, which petition was then granted in January 2018. Our opening appellate brief is currently scheduled to be due May 7, 2018 and the plaintiff’s answering appellate brief is currently scheduled to be due June 7, 2018. Given the current status of this case, we are unable to express a view regarding the ultimate outcome or, if the outcome is adverse, to estimate an amount, or range, of reasonably possible loss. We have defended this case vigorously and will continue to do so.

Insurance Reserves—We use a combination of third-party insurance and self-insurance for a number of risk management activities including workers’ compensation, general liability and employee-related health care benefits. We maintain reserves for our self-insured losses, which are estimated based on actuarial based analysis of historical claims experience. The self-insurance reserve at February 3, 2018 and January 28, 2017 was $2.1 million and $2.3 million.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

10. Fair Value Measurements

We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

•

Level 1—Quoted prices in active markets for identical assets or liabilities;

•

Level 2—Quoted prices for similar assets or liabilities in active markets or inputs that are observable; and

•

Level 3—Inputs that are unobservable.

The following tables summarize assets measured at fair value on a recurring basis (in thousands):

Cash equivalents:

Marketable securities:

Long-term other assets:
Money market funds		1,557		—		—
Equity investments		—		—		116
Total	$	2,614	$	58,579	$	116

The Level 2 marketable securities primarily include state and local municipal securities and variable-rate demand notes. Fair values are based on quoted market prices for similar assets or liabilities or determined using inputs that use readily observable market data that are actively quoted and can be validated through external sources, including third-party pricing services, brokers and market transactions. We review the pricing techniques and methodologies of the independent pricing service for Level 2 investments and believe that its policies adequately consider market activity, either based on specific transactions for the security valued or based on modeling of securities with similar credit quality, duration, yield and structure that were recently traded. We monitor security-specific valuation trends and we make inquiries with the pricing service about material changes or the absence of expected changes to understand the underlying factors and inputs and to validate the reasonableness of the pricing.

Assets measured at fair value on a nonrecurring basis include items such as long-lived assets resulting from impairment, if deemed necessary. There were no material assets measured at fair value on a nonrecurring basis for the fiscal years ended February 3, 2018 and January 28, 2017.

The reconciliation of the income tax provision at the U.S. federal statutory rate to our effective income tax rate is as follows:

	Fiscal Year Ended
	February 3, 2018			January 28, 2017			January 30, 2016

Effective tax rate		44.6	%		35.6	%		37.2	%

On December 22, 2017, the Tax Cuts and Jobs Act, a significant modification of existing U.S. federal tax legislation, was enacted which reduced our U.S. federal tax rate from 35.0% to 21.0%, effective January 1, 2018. The statutory tax rate for the current year reflects this change in tax rate. The decrease in rate resulted in a $0.5 million decrease in our provision for income taxes and an immaterial impact on our deferred tax assets. Our accounting for the income tax effects of the new tax legislation, based on available guidance and interpretation, is complete and we do not anticipate material adjustments to such accounting in future periods.

The components of deferred income taxes are (in thousands):

	February 3, 2018			January 28, 2017
Deferred tax assets:
Deferred rent	$	11,968		$	18,504

At February 3, 2018 and January 28, 2017, we had $39.1 million and $20.3 million of foreign net operating loss carryovers that could be utilized to reduce future years’ tax liabilities. The tax-effected foreign net operating loss carryovers were $9.8 million and $5.1 million at February 3, 2018 and January 28, 2017. The net operating loss carryovers have an indefinite carryfoward period and currently will not expire.

At February 3, 2018 and January 28, 2017, we had valuation allowances on our deferred tax assets of $3.6 million and $0.1 million, respectively. During the fiscal year ended February 3, 2018, we increased the valuation allowance by $3.5 million due to the uncertainty of the realization of deferred tax assets related to net operating loss carryovers in Austria.

We file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. Our U.S. federal income tax returns are no longer subject to examination for years before fiscal 2014 and with few exceptions, we are no longer subject to U.S. state examinations for years before fiscal 2013. We are no longer subject to examination for all foreign income tax returns before fiscal 2012.
