New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	( 2 ) Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016 - 09, "Compensation - Stock Compensation (Topic 718 ): Improvements to Employee Share-Based Payment Accounting," which is intended to simplify 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. We adopted this update during our first fiscal quarter. One provision within ASU No. 2016 - 09 requires the recognition of excess income tax benefits and deficiencies related to share-based payments within income tax expense as a discrete event in the period in which they occur, rather than within additional paid-in capital on a prospective basis. There was no material impact from this provision on income tax expense in the current quarter or nine -month period. The impact of this provision on our future results of operations is difficult to predict as it will depend in part on the market prices for the shares of our common stock on the dates that there are taxable events related to the share-based awards. In connection with another provision within ASU No. 2016 - 09, we have elected to account for forfeitures of share-based awards as an estimate of the number of awards that are expected to vest, which is consistent with our accounting policy prior to adoption. We also adopted the provisions related to changes on the consolidated statements of cash flows on a retrospective basis. As a result, we no longer classify excess income tax benefits as a financing activity, which increased net cash provided by operating activities and reduced net cash provided by financing activities by $488,000 for the nine months ended July 1, 2017. In February 2018, the FASB issued ASU 2018 - 02, “Income Statement – Reporting Comprehensive Income (Topic 220 ): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which allows companies to reclassify stranded income tax effects resulting from the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings in their consolidated financial statements. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years with early adoption permitted. We are evaluating the impact that the adoption of this update will have on our consolidated financial statements. In July 2015, the FASB issued ASU No. 2015 - 11 “Simplifying the Measurement of Inventory,” which requires that an entity measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. We adopted ASU No. 2015 - 11 during our first fiscal quarter. The adoption of this update did not have a material effect on our consolidated financial statements. In May 2017, the FASB issued ASU No. 2017 - 09 “Compensation – Stock Compensation (Topic 718 ): Scope of Modification Accounting.” ASU No. 2017 - 09 was issued to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying its guidance to changes in the terms and conditions of a share-based payment award. ASU No. 2017 - 09 will become effective for us in the first quarter of fiscal 2020. We are evaluating the impact that the adoption of this update will have on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016 - 15 “Statement of Cash Flows Topic 230: Classification of Certain Cash Receipts and Cash Payments.” ASU No. 2016 - 15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows with the objective of reducing existing differences in the presentation of these items. The amendments in ASU No. 2016 - 15 are to be adopted retrospectively and will become effective for us in the first quarter of fiscal 2019. We do not expect the adoption of this update will have a material effect on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016 - 02 “Leases,” which will replace the guidance in Accounting Standards Codification (“ASC”) Topic 840. ASU No. 2016 - 02 was issued to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset. ASU No. 2016 - 02 will become effective for us in the first quarter of fiscal 2020. We are evaluating the impact that the adoption of this update will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014 - 09 “Revenue from Contracts with Customers,” which will supersede nearly all existing revenue recognition guidance under GAAP. ASU No. 2014 - 09 provides that an entity 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. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014 - 09 allows for either full retrospective or modified retrospective adoption and will become effective for us in the first quarter of fiscal 2019. We have substantially completed our evaluation of the impact this update will have on our consolidated financial statements and plan on using the modified retrospective method upon adoption. We have not identified any material changes in the timing of revenue recognition that will result from the adoption of this guidance, but expect it will have a material impact on the disclosures required in our notes to the consolidated financial statements.
