Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Revenue Recognition The Company has adopted Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers” in the first quarter of fiscal year 2018, with a date of initial application of January 1, 2018, using the modified retrospective approach. Comparative information presented has not been adjusted and continues to be reported under ASC 605. The Company applied ASC 606 to all of its contracts with customers. As a result of the adoption, there is no impact to any financial statement line item, and the Company has recorded no impact to opening retained earnings as of January 1, 2018. The Company does not have any material contract assets or receivables from contracts with customers, any revenue recognized in the current period from performance obligations satisfied in previous periods, any contract performance obligations, or any material costs to obtain or fulfill a contract as of September 30, 2018. The Company had a net gift card liability balance of $6.8 million as of September 30, 2018 and $13.1 million as of December 31, 2017. During the thirty-nine weeks ended September 30, 2018, the Company recognized $16.1 million in sales related to gift cards redeemed by customers. Revenue is recognized at the point of sale. The Company’s performance obligations are satisfied upon the transfer of goods to the customer, at the point of sale, and payment from customers is also due at the time of sale. Proceeds from the sale of gift cards are recorded as a liability at the time of sale, and recognized as sales when they are redeemed by the customer and the performance obligation is satisfied by the Company. The nature of goods the Company transfers to customers at the point of sale are inventories, consisting of merchandise purchased for resale. Restricted Cash Restricted cash relates to defined benefit plan forfeitures of approximately $0.7 million and is included in prepaid expenses and other current assets in the consolidated balance sheets. Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers.” ASU No. 2014-09 provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, and estimating the amount of variable consideration to include in the transaction price attributable to each separate performance obligation. Subsequent to the initial standards, the FASB has also issued several ASUs to clarify specific revenue recognition topics. The Company adopted ASC 606 effective January 1, 2018 using the modified retrospective approach. As noted above, there is no impact to any financial statement line item as a result of the adoption, and the Company has recorded no impact to opening retained earnings as of January 1, 2018. The Company has added additional disclosures of disaggregated revenue by type in Note 13, “Segments.” In March 2016, the FASB issued ASU No. 2016-04, “Liabilities-Extinguishments of Liabilities (Subtopic 405-20): Recognition of breakage for certain prepaid stored-value products.” ASU No. 2016-04 provides a narrow scope exception to the guidance in Subtopic 405-20 to require that stored-value breakage be accounted for consistently with the breakage guidance in Topic 606. The amendments in this update contain specific guidance for derecognition of prepaid stored-value product liabilities, thereby eliminating the current and potential future diversity. The guidance was effective for the Company for its fiscal year 2018. The Company adopted this guidance using the modified retrospective approach. As noted above, there is no impact to any financial statement line item as a result of the adoption, and the Company recorded no impact to opening retained earnings as of January 1, 2018. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” This update provides clarifications on the cash flow classification for eight specific cash flow issues: debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. Adoption of this guidance took place during the first quarter of fiscal year 2018, using the retrospective transition method, and the adoption had no impact on the Company’s consolidated financial statements or disclosures. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The amendments in this update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Adoption of this guidance took place prospectively during the first quarter of 2018, and the adoption did not have a material impact on the Company’s consolidated financial statements or disclosures. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments in this update provide guidance about which changes to the terms or conditions of a share-based award require an entity to apply modification accounting in Topic 718. Adoption of this guidance took place prospectively during the first quarter 2018, and the adoption did not have an impact on the Company’s consolidated financial statements or disclosures. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles —Goodwill and Other —Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include internal-use software license). The amendments require an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which service contract implementation costs to capitalize as an asset and which costs to expense. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangements, which includes reasonably certain renewals. The Company adopted this guidance during the third quarter 2018 using the prospective transition approach. Adoption of the guidance did not have a material impact to the Company's financial statements and resulted in capitalization of implementation costs associated with various technology initiatives which are included in other assets in the consolidated balance sheet as of September 30, 2018. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, “Leases (ASC 842).” ASU No. 2016-02 requires lessees to recognize a right-of-use asset and corresponding lease liability for all leases with terms greater than twelve months. Recognition, measurement and presentation of expenses will depend on classification as a financing or operating lease. Certain additional quantitative and qualitative disclosures will also be required. This ASU will be effective for the Company beginning with its 2019 fiscal year. While the Company is still evaluating the impact of this ASU, the Company expects it will result in material increases in assets and liabilities in its consolidated balance sheet and enhanced disclosures. In addition, the Company anticipates that the transition of its financing leases to operating leases under the new standard will result in an increase in rent expense, partially offset by reductions to depreciation and interest expense. The Company does not expect that the adoption of the ASU will have an impact on the Company’s cash flows. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The amendments in this update eliminate the second step of the goodwill impairment test and provide that an entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. The guidance will be effective for the Company for its fiscal year 2020, with early adoption permitted. The Company does not expect this ASU to materially impact the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, “Compensation —Retirement Benefits —Defined Benefit Plans —General (Subtopic 715-20) —Disclosure Framework —Changes to the Disclosure Requirements for Defined Benefit Plans.” The amendments in this update remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The guidance will be effective for the Company for its fiscal year 2020, with early adoption permitted. The Company does not expect this ASU to materially impact the Company’s disclosures. No other new accounting pronouncements issued or effective during the thirty-nine weeks ended September 30, 2018 had, or are expected to have, a material impact on the Company’s consolidated financial statements.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers.” ASU No. 2014-09 provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, and estimating the amount of variable consideration to include in the transaction price attributable to each separate performance obligation. Subsequent to the initial standards, the FASB has also issued several ASUs to clarify specific revenue recognition topics. The Company adopted ASC 606 effective January 1, 2018 using the modified retrospective approach. As noted above, there is no impact to any financial statement line item as a result of the adoption, and the Company has recorded no impact to opening retained earnings as of January 1, 2018. The Company has added additional disclosures of disaggregated revenue by type in Note 13, “Segments.”

In March 2016, the FASB issued ASU No. 2016-04, “Liabilities-Extinguishments of Liabilities (Subtopic 405-20): Recognition of breakage for certain prepaid stored-value products.” ASU No. 2016-04 provides a narrow scope exception to the guidance in Subtopic 405-20 to require that stored-value breakage be accounted for consistently with the breakage guidance in Topic 606. The amendments in this update contain specific guidance for derecognition of prepaid stored-value product liabilities, thereby eliminating the current and potential future diversity. The guidance was effective for the Company for its fiscal year 2018. The Company adopted this guidance using the modified retrospective approach. As noted above, there is no impact to any financial statement line item as a result of the adoption, and the Company recorded no impact to opening retained earnings as of January 1, 2018.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” This update provides clarifications on the cash flow classification for eight specific cash flow issues: debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. Adoption of this guidance took place during the first quarter of fiscal year 2018, using the retrospective transition method, and the adoption had no impact on the Company’s consolidated financial statements or disclosures.

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The amendments in this update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Adoption of this guidance took place prospectively during the first quarter of 2018, and the adoption did not have a material impact on the Company’s consolidated financial statements or disclosures.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments in this update provide guidance about which changes to the terms or conditions of a share-based award require an entity to apply modification accounting in Topic 718. Adoption of this guidance took place prospectively during the first quarter 2018, and the adoption did not have an impact on the Company’s consolidated financial statements or disclosures.

In August 2018, the FASB issued ASU No. 2018-15, “Intangibles —Goodwill and Other —Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include internal-use software license). The amendments require an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which service contract implementation costs to capitalize as an asset and which costs to expense. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangements, which includes reasonably certain renewals. The Company adopted this guidance during the third quarter 2018 using the prospective transition approach. Adoption of the guidance did not have a material impact to the Company's financial statements and resulted in capitalization of implementation costs associated with various technology initiatives which are included in other assets in the consolidated balance sheet as of September 30, 2018.

Recently Issued Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, “Leases (ASC 842).” ASU No. 2016-02 requires lessees to recognize a right-of-use asset and corresponding lease liability for all leases with terms greater than twelve months. Recognition, measurement and presentation of expenses will depend on classification as a financing or operating lease. Certain additional quantitative and qualitative disclosures will also be required. This ASU will be effective for the Company beginning with its 2019 fiscal year. While the Company is still evaluating the impact of this ASU, the Company expects it will result in material increases in assets and liabilities in its consolidated balance sheet and enhanced disclosures. In addition, the Company anticipates that the transition of its financing leases to operating leases under the new standard will result in an increase in rent expense, partially offset by reductions to depreciation and interest expense. The Company does not expect that the adoption of the ASU will have an impact on the Company’s cash flows.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The amendments in this update eliminate the second step of the goodwill impairment test and provide that an entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. The guidance will be effective for the Company for its fiscal year 2020, with early adoption permitted. The Company does not expect this ASU to materially impact the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-14, “Compensation —Retirement Benefits —Defined Benefit Plans —General (Subtopic 715-20) —Disclosure Framework —Changes to the Disclosure Requirements for Defined Benefit Plans.” The amendments in this update remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The guidance will be effective for the Company for its fiscal year 2020, with early adoption permitted. The Company does not expect this ASU to materially impact the Company’s disclosures.

No other new accounting pronouncements issued or effective during the thirty-nine weeks ended September 30, 2018 had, or are expected to have, a material impact on the Company’s consolidated financial statements.
