The update will require, among other items, lessees to recognize the assets and liabilities that arise from most leases on the balance sheet. This guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The ASU must be adopted using a modified retrospective approach and early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which eliminates the transaction-and industry-specific revenue recognition guidance under current GAAP and replaces it with a principles-based approach for determining revenue recognition. The new guidance requires revenue recognition when control of the goods or services transfers to the customer, replacing the existing guidance which requires revenue recognition when the risks and rewards transfer to the customer. Under the new guidance, companies should recognize revenues in amounts that reflect the payment to which a company expects to be entitled in exchange for those goods or services. ASU 2014-09 (and related updates) is effective for interim and annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted for annual periods beginning after December 15, 2016. The Company intends to adopt this standard beginning August 1, 2018. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the standard. The Company is currently assessing the new guidance and whether to adopt using a full retrospective or a modified retrospective approach. Management will conduct surveys of its various business units and analyze contracts and agreements during fiscal 2017 to ensure that all components of the new guidance are appropriately considered for the impact on its consolidated financial statements and disclosures upon adoption.
