New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted In April 2014, the Financial Accounting Standards Board (FASB) issued amended guidance for reporting discontinued operations. The amended guidance changes the criteria for determining when the results of operations are to be reported as discontinued operations and expands the related disclosure requirements. The guidance defines a discontinued operation as a component or group of components that is disposed of or classified as held for sale, which is a strategic shift that has, or will have, a major effect on financial position and results of operations. The Company prospectively adopted this accounting guidance in the first quarter of fiscal year 2016. Its adoption did not have a material impact on the Company's condensed consolidated financial statements. Not Yet Adopted In May 2014, the FASB issued amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The guidance requires an entity to recognize revenue in an amount that reflects the consideration to which an entity expects to be entitled in exchange for the transfer of goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This accounting guidance is effective for the Company beginning in the first quarter of fiscal year 2019 using one of two prescribed retrospective methods. The Company is evaluating the impact of the amended revenue recognition guidance on the Company’s condensed consolidated financial statements.
