Significant Accounting Policies [Text Block]	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - UPDATE Our significant accounting policies are detailed in "Note 2 Summary of Significant Accounting Policies" within Item 8 of our Annual Report on Form 10 -K for the year ended December 31, 2017 filed with the SEC on March 14, 2018. Significant changes to our accounting policies as a result of adopting Topic 606 are discussed below: Revenue Recognition On January 1, 2018, we adopted the new accounting standard ASC 606, “Revenue from Contracts with Customers” and all the related amendments (“new revenue standard"), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new revenue standard was applied using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to accumulated deficit as of January 1, 2018. As a result of the adoption of this standard, certain changes have been made to the condensed consolidated balance sheets. We expect the ongoing impact of the adoption of the new standard to primarily affect the timing of revenue recognition. The most significant impact was on Power and Electromechanical segment revenue that was previously recorded as “sell through." This revenue was previously recorded upon the sale by our customers, who are distributors. Under the new accounting guidance, we record the revenue upon sale to the distributor with an appropriate amount reserved for estimated returns and allowances as the Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. For the Power and Electromechanical segment, their revenue is based upon the transfer of goods and satisfaction of its performance obligations as of a point in time. During the transition this had the effect of having a certain amount of revenue not recorded as revenue but as part of the cumulative effect of the accounting change. In the Energy segment, for the majority of contracts, revenue is still measured over time using the cost-to-cost method. The change that most affected the transition adjustment on Energy revenue was the requirement to limit revenue recognition on contracts without an enforceable right to payment for performance completed to date. Revenue on contracts without a specific enforceable right to payment on work performed to date was "clawed back" as part of the Company's transition adjustment. The cumulative effect adjustment recorded as of January 1, 2018 was a net $1.9 million decrease to accumulated deficit due to a $2.8 million transition adjustment from the Power and Electromechanical segment partially offset by a $( 0.9 ) million transition adjustment from the Energy segment, net of deferred tax. See Note 3 for further discussion of our revenue recognition policies.

Significant changes to our accounting policies as a result of adopting Topic

are discussed below:

Revenue Recognition

January 1, 2018,

we adopted the new accounting standard ASC

606,

“Revenue from Contracts with Customers” and all the related amendments (“new revenue standard"), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new revenue standard was applied using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to accumulated deficit as of

January 1, 2018.

As a result of the adoption of this standard, certain changes have been made to the condensed consolidated balance sheets. We expect the ongoing impact of the adoption of the new standard to primarily affect the timing of revenue recognition.
