Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP.
Principles of Consolidation | The accompanying condensed consolidated financial statements include the accounts of SGC and those subsidiaries in which we have a controlling financial interest. Investments in other entities in which we do not have a controlling financial interest but we exert significant influence are accounted for in our condensed consolidated financial statements using the equity method of accounting. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of SGC and its management, we have made all adjustments necessary to present fairly our consolidated financial position, results of operations and comprehensive income (loss) and cash flows for the periods presented. Such adjustments are of a normal, recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our 2018 10-K. Interim results of operations are not necessarily indicative of results of operations to be expected for a full year.
New Accounting Guidance | New Accounting Guidance - Recently Adopted The FASB issued ASU No. 2016-02, Leases (Topic 842) in 2016. ASU 2016-02 combined with all subsequent amendments (collectively, “ASC 842”) requires balance sheet recognition for all leases with a lease term greater than one year to be recorded as a lease liability (on a discounted basis) with a corresponding right-of-use asset. This guidance also expands the required quantitative and qualitative disclosures for lease arrangements and gives rise to other changes impacting certain aspects of lessee and lessor accounting. We adopted ASC 842 as of January 1, 2019 using the optional transition method provided by ASU 2018-11, and applied both the lessee package of practical expedients and the available lessor practical expedients. During the first quarter of 2019, the FASB issued ASU 2019-01, Leases (Topic 842) to amend ASU 2016-02. This amendment exempts both lessees and lessors from having to provide certain prior year interim disclosure information in the fiscal year in which a company adopts the new leases standard. We have provided the related transition disclosures as of the beginning of 2019 in accordance with ASU 2019-1. See our 2018 10-K Note 1 for the impact on our consolidated financial statements and Note 15 in this Quarterly Report for our lease accounting policy and the impact of our adoption of ASC 842. In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The standard allows companies to make an election to reclassify from Accumulated Other Comprehensive Income (AOCI) to retained earnings the stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. This ASU is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. The amendments in this updated guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. corporate federal income tax rate in the Tax Act is recognized. We adopted this standard effective January 1, 2019. We elected not to reclassify the income tax effects of the Tax Cuts and Jobs Act from AOCI to retained earnings. The adoption of this guidance did not have an effect on our consolidated financial statements. New Accounting Guidance - Not Yet Adopted The FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) in 2016. The new guidance replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans and other financial instruments, we will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The new guidance will be effective for us beginning January 1, 2020. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. We are currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The new guidance amends the disclosure requirements for recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures on fair value measurements in ASC 820. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The new guidance will be effective for us beginning January 1, 2020, with early adoption permitted. We do not plan to early adopt this ASU, and we are currently evaluating the impact of adopting this guidance. We do not expect that any other recently issued accounting guidance will have a significant effect on our consolidated financial statements.
