New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which stipulates that an entity should recognize revenue to depict the transfer of 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. To achieve this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. This update was amended by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date for the Company from the first quarter of fiscal 2017 to the first quarter of fiscal 2018. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This ASU clarifies the implementation guidance on principal versus agent considerations, as it assists in the determination of whether the entity controls the good or service before it is transferred to the customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This ASU clarifies two aspects of Topic 606, including identifying performance obligations and the licensing implementation guidance, while retaining the principles for those areas. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This ASU clarifies three aspects of Topic 606, including the objective of the collectibility criterion, the measurement date for noncash consideration and the requirements for a completed contract. The ASU also includes a practical expedient for contract modifications. Additionally, the amendments allow an entity to exclude amounts collected from customers for all sales taxes from the transaction price. The Company has substantially completed its initial evaluation of the impact of these updates on its consolidated financial statements, including an in-depth assessment of all revenue streams to determine which processes will be affected by these updates and the transition methods for applying the updates. Based on the results of the assessment, the Company is focusing on the construction segment revenue that is recorded using the percentage of completion method and working to quantify the impact to the financial statements. The Company expects that there will be certain adjustments to the retail operations that are not expected to be material to the consolidated financial statements. The Company will adopt the standard using the full retrospective method during the first quarter of fiscal 2018. Leases: Amendments to the FASB Accounting Standards Codification In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification, to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under these amendments, lessees are required to recognize lease assets and lease liabilities for leases historically classified as operating leases under Accounting Standards Codification, Leases (Topic 840). ASU No. 2016-02 is effective for financial statements issued for fiscal years beginning after December 15, 2018, and early adoption is permitted. The Company's operating leases include building and equipment leases. The Company expects the majority of these current operating leases will be impacted by this ASU resulting in increases in assets and liabilities in the Company's consolidated financial statements. While early adoption is permitted for this ASU, the Company intends to adopt the standard during the first quarter of fiscal 2019. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to reduce the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments within ASU No. 2016-15 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Although early adoption is permitted, the Company plans to adopt the standard during the first quarter of fiscal 2018. The Company is currently assessing the impact of this update on its consolidated financial statements. Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, as part of its initiative to reduce complexity in accounting standards. Under these amendments, an entity is required to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments within ASU No. 2016-16 are effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company expects this update to result in a decrease of approximately $174 million to both other assets and deferred tax liabilities in its consolidated financial statements under existing enacted tax rates. The Company intends to adopt the standard during the first quarter of fiscal 2018. Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,to improve the presentation of net periodic pension cost in the income statement.
