Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Adoption of New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09 (“Topic 606”) Revenue from Contracts with Customers. Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605 Revenue Recognition (“Topic 605”), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. Topic 606 only applied to the Nexsan Business, which is reflected in discontinued operations. In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which amends the requirements related to the presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. This ASU requires entities to (1) disaggregate the current-service-cost component from the other components of net benefit cost (the “other components”) and present it with other current compensation costs for related employees in the income statement and (2) present the other components elsewhere in the income statement and outside of income from operations if such a subtotal is presented. In addition, only service costs are eligible for capitalization. The standard will be effective in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company retrospectively adopted ASU No. 2017-07 during the first quarter of 2018. The adoption of ASU 2017-07 resulted in the reclassification of $0.1 million of the Company’s net periodic pension cost, other than service cost, from “Selling, general and administrative” into “Other income (expense), net” in the Condensed Consolidated Statements of Operations for the three months ended September 30, 2018 and 2017, and the reclassification of $0.5 million and $0.3 million for the nine months ended September 30, 2018 and 2017, respectively. New Accounting Pronouncements To Be Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU No. 2016-02 will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees with capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of adopting this standard on its consolidated results of operations and financial condition. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU seeks to help entities reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”), enacted on December 22, 2017. ASU 2018-02 was issued in response to concerns regarding current guidance in GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date, even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income, rather than net income, and as a result the stranded tax effects would not reflect the appropriate tax rate. The amendments of this ASU allow an entity to make a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects, which is the difference between the historical corporate income tax rate of 35.0% and the newly enacted corporate income tax rate of 21.0%. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 31, 2018; however, public business entities are allowed to early adopt the amendments of ASU 2018-02 in any interim period for which the financial statements have not yet been issued. The amendments of this ASU may be applied either at the beginning of the period (annual or interim) of adoption or retrospectively to each of the period(s) in which the effect of the change in the U.S. federal corporate tax rate in the Tax Reform Act is recognized. The Company is currently assessing the impact of adopting this standard on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in ASU No. 2018-03 clarify certain aspects of the guidance issued in ASU No. 2016-01 and are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. The Company does not expect this standard to have a material effect on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which largely aligns the measurement and classification guidance for share-based payments to nonemployees with the guidance for share-based payments to employees. The ASU also clarifies that any share-based payment issued to a customer should be evaluated under ASC 606, Revenue from Contracts with Customers. The ASU requires a modified retrospective transition approach. For the Company, the ASU is effective as of January 1, 2019. The Company does not expect this standard to have a material effect on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-08, Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. The ASU applies to entities that receive or make contributions, which primarily are not-for-profit entities but also affects business entities that make contributions. In the context of business entities that make contributions, the FASB clarified that a contribution is conditional if the arrangement includes both a barrier for the recipient to be entitled to the assets transferred and a right of return for the assets transferred (or a right of release of the business entity’s obligation to transfer assets). The recognition of contribution expense is deferred for conditional arrangements and is immediate for unconditional arrangements. The ASU requires modified prospective transition to arrangements that have not been completed as of the effective date or that are entered into after the effective date, but full retrospective application to each period presented is permitted. For the Company, the ASU is effective as of January 1, 2019. The Company does not expect this standard to have a material impact on its consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, which amends ASU No. 2016-02, Leases. The new ASU includes certain clarifications to address potential narrow-scope implementation issues which the Company is incorporating into its assessment and adoption of ASU No. 2016-02. This ASU has the same transition requirements and effective date as ASU No. 2016-02, which for the Company is January 1, 2019. The Company does not expect this standard to have a material impact on its consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which amends ASU No. 2016-02, Leases. The new ASU offers an additional transition method by which entities may elect not to recast the comparative periods presented in financial statements in the period of adoption and allows lessors to elect a practical expedient to not separate lease and nonlease components when certain conditions are met. This ASU has the same transition requirements and effective date as ASU No. 2016-02, which for the Company is January 1, 2019. The Company does not expect this standard to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, amends, and adds disclosure requirements for fair value measurements. The amended and new disclosure requirements primarily relate to Level 3 fair value measurements. For the Company, the ASU is effective as of January 1, 2020. The removal and amendment of certain disclosures may be early adopted with retrospective application while the new disclosure requirements are to be applied prospectively. As this ASU relates only to disclosures, there will be no impact to the Company’s consolidated results of operations and financial condition. In August 2018, the FASB issued ASU No. 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans, which makes minor changes to the disclosure requirements related to defined benefit pension and other postretirement plans. The ASU requires a retrospective transition approach. For the Company, the ASU is effective as of January 1, 2021. As this ASU relates only to disclosures, there will be no impact to the Company’s consolidated results of operations and financial condition.

Adoption of New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09 (“Topic 606”) Revenue from Contracts with Customers. Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605 Revenue Recognition (“Topic 605”), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services.

On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. Topic 606 only applied to the Nexsan Business, which is reflected in discontinued operations.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which amends the requirements related to the presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. This ASU requires entities to (1) disaggregate the current-service-cost component from the other components of net benefit cost (the “other components”) and present it with other current compensation costs for related employees in the income statement and (2) present the other components elsewhere in the income statement and outside of income from operations if such a subtotal is presented. In addition, only service costs are eligible for capitalization. The standard will be effective in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company retrospectively adopted ASU No. 2017-07 during the first quarter of 2018. The adoption of ASU 2017-07 resulted in the reclassification of $0.1 million of the Company’s net periodic pension cost, other than service cost, from “Selling, general and administrative” into “Other income (expense), net” in the Condensed Consolidated Statements of Operations for the three months ended September 30, 2018 and 2017, and the reclassification of $0.5 million and $0.3 million for the nine months ended September 30, 2018 and 2017, respectively.
