Basis of Presentation	NOTE 1 — Basis of Presentation The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by Christopher & Banks Corporation and its subsidiaries (collectively referred to as “Christopher & Banks”, “the Company”, “we” or “us”) pursuant to the current rules and regulations of the United States ("U.S.") Securities and Exchange Commission. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been omitted, pursuant to such rules and regulations. These unaudited condensed consolidated financial statements, except the condensed consolidated balance sheet as of January 28, 2017 derived from the Company's audited financial statements, should be read in conjunction with the audited financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended January 28, 2017. The results of operations for the interim period shown in this report are not necessarily indicative of results to be expected for the full fiscal year. In the opinion of management, the information contained herein reflects all adjustments, consisting only of normal adjustments, except as otherwise stated in these notes, considered necessary to present fairly our financial position, results of operations, and cash flows as of April 29, 2017, and April 30, 2016 and for all periods presented. Recently issued accounting pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance under ASU No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition requirements and provides a new comprehensive revenue recognition model that requires entities to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers, Deferral of the Effective Date, which defers the effective date of the new revenue recognition standard by one year. As a result, ASU 2014-09 is effective retrospectively for fiscal years and interim periods within those years beginning after December 15, 2017. Adoption is allowed by either the full retrospective or modified retrospective approach. We do not believe the adoption of this standard will have a material impact on our consolidated financial statements. The new revenue standard will require the Company to recognize gift card breakage proportional to actual gift card redemptions. The Company continues to evaluate the merits of adopting the standard under the full retrospective or modified retrospective approach, which will require certain reclassifications. In February 2016, the FASB issued ASU 2016-02, Leases, which requires that lease arrangements longer than twelve months result in an entity recognizing an asset and liability. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the guidance and its impact on our condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 addresses simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The adoption of ASU 2016-09 did not have a material impact on the Company's consolidated financial statements mostly due to the impact of the tax valuation allowance. We reviewed all other significant newly-issued accounting pronouncements and concluded they are either not applicable to our operations, or that no material effect is expected on our consolidated financial statements as a result of future adoption.
