Accounting Changes and Error Corrections [Abstract]
Effect of Recent Accounting Updates	*Accounting Updates Not Yet Effective* Changes to U.S. GAAP are established by the Financial Accounting Standards Board (the FASB) in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considered the applicability and impact of all ASUs. ASUs not mentioned below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. In May 2014, the FASB issued ASU 2014-09 (Revenue from Contracts with Customers (Topic 606)) and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016, May 2016 and December 2016 within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively (ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively, and collectively, Topic 606) to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. Topic 606 supersedes nearly all existing revenue recognition guidance under GAAP. Topic 606 is principles-based and provides a five-step model to determine when and how revenue is recognized. It is possible more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The core principle is 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. To achieve that core principle, an entity should apply the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation. Topic 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This standard, as amended, will be effective for the Company for annual and interim reporting periods beginning after December 15, 2017. This standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. Early adoption is permitted, but no earlier than calendar 2017. This standard could impact the timing and amounts of revenue recognized. The Company is currently evaluating the impact of this standard on its consolidated financial statements. The Company has not yet selected a transition method and in preparation for our adoption of the new standard in our 2018 fiscal year, we are obtaining representative samples of contracts and other forms of agreements with our customers in the U.S. and international locations and are evaluating the provisions contained therein in light of the five-step model specified by this standard. While we do not believe there will be a material impact to our revenues upon adoption, we are continuing to evaluate the impact to our revenues and our preliminary assessments are subject to change. We are also continuing to evaluate the provisions of Topic 606 related to costs for obtaining customer contracts. In January 2016, the FASB issued ASU 2016-01 (Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities) the main objective of which is to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information and address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard will be effective for the Company for annual and interim reporting periods beginning on or after December 15, 2017, and early adoption is permitted. The Company is currently evaluating the impact of this standard but we do not expect the adoption of it to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (Leases (Topic 842)), which requires lessees to recognize a right-of-use asset and a lease liability on their balance sheet for virtually all of their leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, this standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. For lessees, operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). While this standard maintains similar accounting for lessors as under ASC 840, this standard reflects updates to, among other things, align with certain changes to the lessee model. This standard will be effective for the Company for annual and interim reporting periods beginning on or after December 15, 2018, and early adoption is permitted. Although we have not completed our assessment, we believe adoption of this standard may have a significant impact on our consolidated balance sheets. However, we do not expect the adoption to change the recognition, measurement or presentation of lease expense within our consolidated statements of operations or the consolidated statements of cash flows. We currently expect that most of our operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon our adoption of the standard, which will increase our total assets and total liabilities that we report relative to such amounts prior to adoption. Information about our undiscounted future lease payments and the timing of those payments is in Note 8, Commitments and Contingencies. In August 2016, the FASB issued ASU 2016-15 (Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments), which clarifies the treatment of several cash flow categories. In addition, ASU 2016-15 clarifies that when cash receipts and cash payments have aspects of more than one class of cash flows and cannot be separated, classification will depend on the predominant source or use. This standard will be effective for the Company for annual and interim reporting periods beginning after December 15, 2017, and early adoption permitted. This standard should be applied using a retrospective transition method to each period presented. The Company is currently evaluating the impact of this standard on its consolidated financial statements. *Accounting Updates Recently Adopted by the Company* On January 1, 2017, we adopted ASU 2015-11 (Inventory (Topic 330): Simplifying the Measurement of Inventory), which applies to inventory that is measured using first-in, first-out (FIFO) or average cost. As required by ASU 2015-11, we measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement was unchanged for inventory that is measured using last-in, last-out (LIFO). The Company adopted this standard on a prospective basis. The adoption of this standard did not have a material impact on its consolidated financial statements. On January 1, 2017, we adopted ASU 2015-17 (Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes). The amendments in this standard require entities that present a classified balance sheet to classify all deferred tax liabilities and assets as a noncurrent amount. The requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount was not affected by the amendments in this standard. Additionally, the amendments in this standard align the deferred income tax presentation with the requirements in International Accounting Standards (IAS) 1 (Presentation of Financial Statements). The Company adopted this standard on a prospective basis. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements as its deferred tax assets and liabilities are currently in a full valuation allowance. Prior periods were not retrospectively adjusted. On January 1, 2017, we adopted ASU 2016-09 (Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting). As required by ASU 2016-09, all income tax effects of awards, including excess tax benefits, recognized on stock-based compensation expense are reflected in the condensed consolidated statements of operations as a component of the provision for income taxes on a prospective basis. As required by ASU 2016-09, all tax related cash flows recognized on stock-based compensation expense are classified as an operating activity in our condensed consolidated statements of cash flows on a prospective basis. Accordingly, prior periods have not been adjusted. Additionally, ASU 2016-09 allows companies to make a policy election to account for forfeitures either upon occurrence or by estimating forfeitures. We have elected to continue estimating forfeitures expected to occur in order to determine the amount of compensation cost to be recognized each period. See Note 6 above for additional information. On January 1, 2017, we adopted ASU 2017-03 (Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323); Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 Emerging Issues Task Force (EITF) Meetings (SEC Update)), which amends certain topics of the ASC as defined in this ASU and also adds an SEC paragraph and amends other topics pursuant to an SEC Staff Announcement made at the September 22, 2016 EITF meeting. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. There have been no other significant changes in our reported financial position or results of operations and cash flows as a result of our adoption of new accounting pronouncements or changes to our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.
