Recent Accounting Pronouncements	Recently Adopted Accounting Policies In November 2015, the Financial Accounting Standards Board issued new accounting guidance that requires entities to present deferred tax assets and deferred tax liabilities, along with any related valuation allowance, as noncurrent in a balance sheet. The standard is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted.

Prior periods were not retrospectively adjusted. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board issued new accounting guidance regarding employee share-based payment accounting. The new guidance simplifies certain aspects of the accounting for share-based payment transactions, including income tax requirements, forfeitures and presentation on the balance sheet and statement of cash flows. The new guidance is effective for the Company for annual and interim periods beginning after December 15, 2016. The Company is assessing what impacts the adoption of this new guidance will have on its Consolidated Financial Statements. In November 2015, the Financial Accounting Standards Board issued an effective date for a new leasing standard that will require substantially all leases to be recorded on the balance sheet. The standard is effective for the Company’s first quarter of its 2019 fiscal year; early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is assessing what impacts this new standard will have on its Consolidated Financial Statements. In July 2015, the Financial Accounting Standards Board issued an accounting standards update that will simplify the measurement of inventory for companies. The standard differentiates the valuation methods used to measure inventory based on the type of inventory method utilized by a company. Companies using the first-in, first-out method and the average cost method will measure inventory at the net realizable value method to measure inventory. Companies using the last-in, first-out method and the retail method will use the lower of cost or market to measure inventory. The standard is effective for the Company’s first quarter of its 2017 fiscal year; early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is assessing what impacts this new standard will have on its Consolidated Financial Statements. In May 2014, the Financial Accounting Standards Board issued an accounting standards update that will supersede most current revenue recognition guidance and modify the accounting treatment for certain costs associated with revenue generation. The core principle of the revised revenue recognition standard is that an entity should recognize revenue to depict the transfer of 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, and provides several steps to apply to achieve that principle. In addition, the new guidance enhances disclosure requirements to include more information about specific revenue contracts entered into by the entity. The standard is effective for the Company’s first quarter of its 2018 fiscal year; early adoption is permitted as of the original effective date. The Company is assessing what impacts this new standard will have on its Consolidated Financial Statements.
