Recently Issued Accounting Standards	16.Recently Issued Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes virtually all existing revenue recognition guidance. Throughout 2016 and in early 2017, additional accounting guidance was issued to clarify the not yet effective revenue recognition guidance issued in May 2014. The ASU provides for full retrospective, modified retrospective, or use of the cumulative effect method during the period of adoption. During 2017, we established an implementation team and began a detailed analysis of our contracts in place during the retrospective period. The requirements in ASU No. 2014-09 are effective during interim and annual periods beginning after December 15, 2017. In fiscal 2017, we performed an initial assessment of the impact of ASU No. 2014-09 with the assistance of an outside consultant. Our assessment was based on a bottoms-up approach, in which we analyzed our existing contracts and current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to our contracts. We are in the process of implementing the appropriate changes to our business processes, systems or controls to support recognition and disclosure under the new standard. Our findings and progress toward implementation of the standard are periodically reported to management. Currently, we do not expect the impact of adopting ASU No. 2014-09 to be material to our total net revenues and operating income (loss) or to our consolidated balance sheet because our performance obligations, which determine when and how revenue is recognized, are not materially changed under the new standard, thus, revenue associated with the majority of our contracts will continue to be recognized as services are provided. We will adopt this standard on October 1, 2018 and, based on our evaluation to date, we anticipate using the modified retrospective method; however, we are still in the process of finalizing our documentation and assessment of the impact of the standard on our financial results and related disclosures. We anticipate additional disclosures in future filings related to our planned adoption of this standard. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-02 will require organizations that lease assets — referred to as “lessees” — to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASU No. 2016-02, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Lessor accounting remains substantially similar to current GAAP. In addition, disclosures of leasing activities are to be expanded to include qualitative along with specific quantitative information. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU No. 2016-02 initially mandated a modified retrospective transition method with an option to use certain practical expedients. Since a portion of our contract drilling revenue will be subject to this new leasing guidance, we expect to adopt this new lease guidance in the first quarter of fiscal 2019 concurrently with ASU No. 2014-09. In addition, the Company expects to apply certain transition practical expedients allowed by the standard. We are in the process of implementing changes to our business processes, systems and controls to support recognition and disclosure under the new standard. We are also in the process of implementing a lease accounting software to control the lease data. We have performed a scoping and preliminary assessment of the impact of this new standard. Our findings and progress toward implementation of the standard are periodically reported to management. As a lessor, we expect the adoption of this new standard will apply to our drilling contracts. As a lessee, this standard will primarily impact us in situations where we lease real estate and equipment, for which we will recognize a right-of-use asset and a corresponding lease liability on our consolidated balance sheet. In January 2018, the FASB issued a proposed ASU affecting the amendments in ASU No. 2016-02 providing entities with an additional (and optional) transition method of adoption resulting in a cumulative effect adjustment upon adoption. The amendments in the proposed update would provide lessors with a practical expedient to not separate nonlease components from the related lease components if certain requirements are met. The Company expects to adopt the new lease guidance utilizing the new proposed transition method of adoption as included in the proposed ASU, if codified. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. The provisions of ASU No. 2016-01 are effective for interim and annual periods starting after December 15, 2017. At adoption, a cumulative-effect adjustment to beginning retained earnings will be recorded. We will adopt this standard on October 1, 2018. Subsequent to adoption, changes in the fair value of our available-for-sale investments will be recognized in net income and the effect will be subject to stock market fluctuations. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses. The ASU sets forth a "current expected credit loss" (CECL) model which requires companies to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This standard is effective for interim and annual periods beginning after December 15, 2019. We are currently assessing the impact this standard will have on our consolidated financial statements and disclosures. In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). The ASU is intended to reduce diversity in practice in presentation and classification of certain cash receipts and cash payments by providing guidance on eight specific cash flow issues. The ASU is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted, including adoption during an interim period. We are currently assessing the impact this standard will have on our consolidated statement of cash flows. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows - Restricted Cash. The ASU requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. The ASU is effective for interim and annual periods beginning after December 31, 2017 and early adoption is permitted, including adoption during an interim period. We will adopt the guidance beginning October 1, 2018 applied retrospectively to all periods presented. The adoption is not expected to have a material impact on our consolidated financial position or cash flows. 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. ASU No. 2017-07 will change how employers that sponsor defined benefit pension and/or other post-retirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Employers will present the other components of the net periodic benefit cost separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. This standard is effective for annual periods or any interim periods beginning after December 15, 2017, including interim periods within those periods. Early adoption is permitted. We do not expect the new guidance to have a material impact on our financial condition or results of operation.
