Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance that simplifies the measurement of goodwill impairment. Under this new guidance, an impairment charge, if triggered, is calculated as the difference between a reporting unit’s carrying value and fair value, but it is limited to the carrying value of goodwill. Current guidance, however, requires an impairment charge to be calculated as the excess of the carrying value of goodwill over its implied fair value. During the second quarter of fiscal 2017, we elected to early-adopt this guidance on a prospective basis, and during the third quarter of fiscal 2017, we will conduct our annual goodwill impairment testing. Among our larger reporting units, the fair value of the Teavana reporting unit was closest to its carrying value per our most recently completed test in third quarter of fiscal 2016. As of April 2, 2017, goodwill attributed to this unit was $467.5 million. We will continue to assess its recoverability as management evaluates the performance and strategy of the reporting unit. In October 2016, the FASB issued guidance on the accounting for income tax effects of intercompany sales or transfers of assets other than inventory. The guidance requires entities to recognize the income tax impact of an intra-entity sale or transfer of an asset other than inventory when the sale or transfer occurs, rather than when the asset has been sold to an outside party. The guidance will require a modified retrospective application with a cumulative catch-up adjustment to opening retained earnings at the beginning of our first quarter of fiscal 2019 but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In June 2016, the FASB issued guidance on the measurement and recognition of credit losses on most financial assets. For trade receivables, loans, and held-to-maturity debt securities, the current probable loss recognition methodology is being replaced by an expected credit loss model. For available-for-sale debt securities, the recognition model on credit losses is generally unchanged, except the losses will be presented as an adjustable allowance. The guidance will be applied retrospectively with the cumulative effect recognized as of the date of adoption. The guidance will become effective at the beginning of our first quarter of fiscal 2021 but can be adopted as early as the beginning of our first quarter of fiscal 2020. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In March 2016, the FASB issued guidance related to stock-based compensation, which changes the accounting and classification of excess tax benefits and minimum tax withholdings on share-based awards. The guidance becomes effective at the beginning of our first quarter of fiscal 2018 but permits adoption in an earlier period. With this adoption, excess tax benefits and tax deficiencies related to stock-based compensation will be prospectively reflected as income tax expense in our consolidated statement of earnings instead of additional paid-in capital on our consolidated balance sheet. Additionally, within our consolidated statement of cash flows, this guidance will require excess tax benefits to be presented as an operating activity, rather than a financing activity, in the same manner as other cash flows related to income taxes. We are currently evaluating the timing and impact of adopting this guidance; however, as a result of the presentation requirements associated with the standard, we expect this adoption to have a significant impact on income tax expense and earnings per share, as reported in our consolidated statement of earnings, and consolidated statement of cash flows. In March 2016, the FASB issued guidance for financial liabilities resulting from selling prepaid stored value products that are redeemable at third-party merchants. Under the new guidance, expected breakage amounts associated with these products must be recognized proportionately in earnings as redemption occurs. Our current accounting policy of applying the remote method to all of our stored value cards, including cards redeemable at the third-party licensed locations, will no longer be allowed. The guidance will become effective at the beginning of our first quarter of fiscal 2019, with the option to adopt in an earlier period. As the guidance and timing of transition are consistent with the new revenue recognition standard issued by the FASB in May 2014 and discussed below, we expect to implement the provisions of both standards in the same period. In February 2016, the FASB issued guidance on the recognition and measurement of leases. Under the new guidance, lessees are required to recognize a lease liability, which represents the discounted obligation to make future minimum lease payments, and a corresponding right-of-use asset on the balance sheet for most leases. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. Enhanced disclosures will also be required to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leases. The guidance will require modified retrospective application at the beginning of our first quarter of fiscal 2020, with optional practical expedients, but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements. We expect this adoption will result in a material increase in the assets and liabilities on our consolidated balance sheets but will likely have an insignificant impact on our consolidated statements of earnings. In April 2015, the FASB issued guidance on the financial statement presentation of debt issuance costs. This guidance requires these costs to be presented in the balance sheet as a reduction of the related debt liability rather than as an asset. We retrospectively adopted this guidance in the first quarter of fiscal 2017, which resulted in the reclassification of $17.0 million of debt issuance costs previously presented in prepaid expenses and other current assets and other long-term assets to long-term debt in our consolidated balance sheet as of October 2, 2016. Components of our long-term debt and aggregate debt issuance costs and unamortized premium are disclosed in Note 7, Debt. In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original effective date of the guidance would have required us to adopt at the beginning of our first quarter of fiscal 2018; however, the FASB approved an optional one-year deferral of the effective date. The new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the overall impact this guidance will have on our consolidated financial statements, as well as the expected timing and method of adoption. Based on our preliminary assessment, we determined the adoption will change the timing of recognition and classification of our stored value card breakage income, which is currently recognized using the remote method and recorded in interest income and other, net. The new guidance will require application of the proportional method and classification within total net revenues on our consolidated statements of earnings. Additionally, the new guidance requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. We are continuing our assessment, which may identify other impacts.
