New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This ASU requires organizations to replace the incurred loss impairment methodology with a methodology reflecting expected credit losses with considerations for a broader range of reasonable and supportable information to substantiate credit loss estimates. This ASU is effective for annual reporting periods beginning after December 15, 2019. The Company is currently undertaking a data analysis and is taking measures so that its systems capture data applicable to the standard. In addition, the Company is undergoing a readiness assessment with an external consultant that began in the first quarter of fiscal 2018. ASU No. 2016-04, Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products This ASU requires organizations to derecognize the deposit liabilities for unredeemed prepaid stored-value products (i.e. breakage) consistent with breakage guidance in Topic 606, Revenue from Contracts with Customers. This ASU is effective for annual reporting periods beginning after December 15, 2017, and the Company expects the impact to its consolidated financial statements to be minimal. ASU No. 2016-02, Leases (Topic 842): Amendments to the Leases Analysis This ASU requires organizations to recognize lease assets and lease liabilities on the balance sheet, along with disclosing key information about leasing arrangements. This update is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. The Company has finalized its initial assessment of the ASU and expects that the standard will be immaterial to its consolidated financial statements with the Company's leases. ASU No. 2014-09, Revenue Recognition – Revenue from Contracts with Customers (Topic 606) This ASU provides guidance on when to recognize revenue from contracts with customers. The objective of this ASU is to eliminate diversity in practice related to this topic and to provide guidance that would streamline and enhance revenue recognition requirements. The ASU defines five steps to recognize revenue, including identify the contract with a customer, identify the performance obligations in the contract, determine a transaction price, allocate the transaction price to the performance obligations and then recognize the revenue when or as the entity satisfies a performance obligation. This update is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and the Company is currently assessing all income streams, including different prepaid card programs, so as to ascertain how revenues, including breakage, will be recognized under the standard. ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes This ASU requires entities with a classified balance sheet to present all deferred tax assets and liabilities as noncurrent. This update was effective for annual and interim periods in fiscal years beginning after December 15, 2016, and did not have an impact on the Company's consolidated financial statements. ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments This ASU addresses eight classification issues related to the statement of cash flows including: debt prepayment or debt extinguishment costs, settlement of zero-coupon bonds, 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, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and the Company expects the impact to its consolidated financial statements to be minimal. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities This ASU requires entities to shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments in this update require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and is not expected to have a material impact on the Company's consolidated financial statements. ASU 2017-12, Receivables - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities This ASU targets improving the accounting treatment for hedging activities and provides more flexibility in defining what can be hedged, while reducing earnings volatility due to ineffective hedges, and minimizing documentation requirements. The ASU also offers the ability to reclassify prepayable debt securities from HTM to AFS and subsequently sell the securities, as long as the securities are eligible to be hedged. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted in any interim period or fiscal year before the effective date. The Company early adopted ASU 2017-12 as of October 1, 2017. The Company reclassified certain prepayable debt securities from HTM to AFS during the first quarter of fiscal 2018. See Note 5 to the Notes to Condensed Consolidated Financial Statements for additional information on the securities reclassified. ASU 2016-01, Financial Instruments (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities This ASU allows equity investments that do not have a readily determinable fair value to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The ASU also requires enhanced disclosure about those investments. The ASU simplifies the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. Entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet are required to use the exit price notion consistent with Topic 820, Fair Value Measurement. This update will be effective for annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2016-01 on its consolidated financial statements.
