Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements Recently Adopted In October 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update that amends the existing guidance on the income tax effects of intra-entity asset transfers with the exception of transfers of inventory. The update requires the recognition of tax expense when an intra-entity asset transfer occurs as opposed to being deferred under the existing guidance. The Company adopted the new guidance on February 1, 2018 using the modified retrospective approach. The net cumulative effect of this change was $4,496 and was recognized as a decrease to retained earnings as of February 1, 2018. In May 2014, the FASB issued an accounting standards update that clarifies the principles for recognizing revenue from contracts with customers. The update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance, including industry-specific guidance. The update states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in the amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Entities are required to apply the following steps when recognizing revenue under the update: (1) identify the contract(s) with a customer; (2) identify the performance obligation in the contract(s); (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract(s); and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company adopted this update on February 1, 2018 using the modified retrospective approach and applied the new guidance to all contracts that were not completed as of the adoption date. Adoption resulted in a change in the timing of recognizing breakage income related to its gift cards and in recognizing estimated sales returns on a gross basis on its balance sheet. The net cumulative effect of this change was $11,060, after tax, and was recognized as an increase to retained earnings as of February 1, 2018. The difference in financial statement line item amounts in the current period under the new accounting guidance as compared to what the balances would be as reported under the previous accounting guidance is immaterial. Recently Issued In June 2016, the FASB issued an accounting standards update that introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. This includes loan commitments, accounts receivable, trade receivables, and certain off-balance sheet credit exposures. The guidance also modifies the impairment model for available-for-sale debt securities. The update will be effective for the Company on February 1, 2020 and early adoption is permitted. The Company is currently assessing the potential effects this update may have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued an accounting standards update that amends the existing accounting standards for lease accounting. This update requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Lessees are permitted to make an accounting policy election to not recognize the asset and liability for leases with a term of 12 months or less. The update will be effective for the Company on February 1, 2019 and early adoption is permitted. The update requires a modified retrospective transition approach, which includes a number of practical expedients. While the Company expects adoption to result in a significant increase in the assets and liabilities recorded on its balance sheet, the Company is currently assessing the overall impact on its consolidated financial statements and related disclosures.
