New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements The following is a summary of new accounting pronouncements that apply or may apply to our business. In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new standard on revenue recognition that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The new standard contains a five-step approach that entities will apply to determine the measurement of revenue and timing of when it is recognized, including (i) identifying the contract(s) with a customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to separate performance obligations, and (v) recognizing revenue when (or as) each performance obligation is satisfied. The new standard requires a number of disclosures intended to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue, and the related cash flows. The disclosures include qualitative and quantitative information about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 and we plan to adopt the standard using the modified retrospective transition method. The modified retrospective transition approach will recognize any changes from the beginning of the year of initial application through retained earnings with no restatement of comparative periods. The more significant effects on our existing accounting policies will be associated with our power transformer business. Under the new standard, revenue for our power transformers will be recognized over time, which is a change from our current accounting policy of recognizing revenue for power transformers at a point in time. We have yet to finalize our analysis of the initial impact of adopting the new standard, but currently estimate that the adoption will result in a decrease to our retained deficit, as of January 1, 2018, of less than $6.0. We do not believe the adoption will have a material impact on our future results of operations. In February 2016, the FASB issued an amendment to existing guidance that requires lessees to recognize assets and liabilities for the rights and obligations created by long-term leases. In addition, this amendment requires new qualitative and quantitative disclosures about leasing arrangements. This standard is effective for annual periods beginning on or after December 15, 2018 for public business entities, and interim periods within those fiscal years. Early adoption is permitted, and adoption must be applied on a modified retrospective basis. We are currently evaluating the effect this new standard will have on our consolidated financial statements. In March 2016, the FASB issued an amendment to existing guidance that simplifies several aspects of the accounting for employee shared-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods. The standard requires that all excess tax benefits and deficiencies previously recorded in “equity” be prospectively recorded to the statement of operations within the income tax (provision) benefit. These excess tax benefits and deficiencies are primarily driven by fluctuations in our stock price between the date a share-based award is granted and the date the award vests. As such, under this standard we could experience volatility in our income tax (provision) benefit and effective income tax rate. The standard also requires excess tax benefits or deficiencies be presented as an operating activity within the statement of cash flows rather than as a financing activity. We adopted this guidance on January 1, 2017. As such, we recognized income tax benefits of $0.6 in our 2017 consolidated statement of operations and classified such amount within operating activities of our 2017 consolidated statement of cash flows. Lastly, we elected to continue estimating stock-based compensation award forfeitures in determining the amount of compensation expense to be recognized each period. In August 2016, the FASB issued an amendment to existing guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented in the statement of cash flows. This amendment provides clarification on eight specific cash flow presentation issues. The issues include, but are not limited to, debt prepayment or extinguishment costs, settlement of zero-coupon debt, proceeds from the settlement of insurance claims, and cash receipts from payments on beneficial interests in securitization transactions. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted. We will adopt the standard, effective January 1, 2018. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued an amendment to simplify the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires that an entity recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This amendment is effective for annual reporting periods beginning after December 31, 2019, including interim periods within those annual reporting periods. Early adoption is permitted. The impact of this amendment on our consolidated financial statements will depend on the results of future goodwill impairment tests. In March 2017, the FASB issued an amendment to revise the presentation of net periodic pension and postretirement benefit cost. The amendment requires the service cost component to be presented separately from the other components of net periodic pension and postretirement benefit cost. Service cost will be presented with other employee compensation costs within operating income. The other components of net periodic pension and postretirement benefit cost, such as interest cost, expected return on plan assets, amortization of prior service cost/credits, and gains or losses, are required to be separately presented outside of operating income. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual periods. The amendment to the presentation in the income statement of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost shall be applied retrospectively. We will adopt the standard, effective January 1, 2018. The adoption is not expected to have a material impact on our consolidated financial statements. See Note 9 for details of our pension and postretirement expense. In August 2017, the FASB issued significant amendments to hedge accounting. The FASB’s new guidance will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The amendments can be adopted immediately in any interim or annual period (including the current period). The mandatory effective date for calendar year-end public companies is January 1, 2019. We are currently evaluating the effect this amendment will have on our consolidated financial statements. In February 2018, the FASB amended its guidance for reporting comprehensive income to reflect the potential impacts of the reduction in the corporate tax rate resulting from the Tax Cuts and Jobs Act. The amendment gives the option of reclassifying the stranded tax effects within AOCI to retained earnings during the fiscal year or quarter in which the effect of the lower tax rate is recorded. The amendment is effective for years beginning after December 15, 2018, with early adoption permitted. We expect to adopt this amendment as of January 1, 2018, with the impact not expected to be material to our retained deficit.
