14. RECENT ACCOUNTING PRONOUNCEMENTS	14. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted Inventory Measurement In July 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that requires management to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued an accounting standard update related to deferred tax assets and liabilities. This standard simplifies the presentation of deferred income taxes to be classified as noncurrent in the consolidated balance sheet. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Share-Based Compensation In March 2016, the FASB released an accounting standard update that simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Accounting Standards Not Yet Adopted Revenue Recognition In May 2014, the FASB issued an accounting standard update related to revenue from contracts with customers. This standard sets forth a new five-step revenue recognition model which replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in the prior accounting guidance. The standard provides alternative methods of initial adoption and will become effective for the Company beginning in the first quarter of fiscal 2019. The FASB has issued several updates to the standard which i) defer the original effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. ii) clarify the application of the principal versus agent guidance. and iii) clarify the guidance on inconsequential and perfunctory promises and licensing. In May 2016, the FASB issued an update to address certain narrow aspects of the guidance including collectibility criterion, collection of sales taxes from customers, noncash consideration, contract modifications and completed contracts. This issuance does not change the core principle of the guidance in the initial topic issued in May 2014. In December 2016, the FASB issued updated guidance regarding revenue from contracts with customers. Some topics that could impact the Company include corrections and improvements around the following: contract costs impairment testing, disclosure of remaining performance obligations and prior period obligations, contract modifications, and contract asset versus receivable. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. Financial Instruments In January 2016, the FASB issued an accounting standard update related to recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This standard is effective for us in fiscal year 2020. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In June 2016, the FASB issued an accounting standard update that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2021 on a modified retrospective basis, and early adoption in fiscal 2020 is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. Leases In February 2016, the FASB issued authoritative guidance related to leases. This guidance requires management to present all leases greater than one year on the balance sheet as a liability to make payments and an asset as the right to use the underlying asset for the lease term. This new standard will be effective for us in fiscal year 2020, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments on the statement of cash flows. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated statements of cash flows. Intra-Entity Asset Transfers In October 2016, the FASB issued an accounting standard update that requires recognition of the income tax consequences of intra-entity transfers of assets (other than inventory) at the transaction date. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a modified retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. Restricted Cash In November 2016, the FASB issued authoritative guidance related to statements of cash flows. This guidance clarifies that 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. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
