Accounting Policies
Estimates	Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted the accounting standard ASC 606, Revenue from Contracts with Customers and all the related amendments (“new revenue standard” or “ASU 2014-09”) to all contracts using the modified retrospective method. The adoption of ASU 2014-09 was not material to the Company and as such, there was no cumulative effect upon the January 1, 2018 adoption date. As the impact of the new revenue standard is not material to the Company, there is no pro-forma disclosure presented for the three and nine months ended September 30, 2018. The Company expects the impact of the adoption of the new standard to be immaterial to the Company’s financial statements on an ongoing basis. The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. The Company’s revenue for product sales is recognized on a point in time model, at the point control transfers to the customer, which is generally when products are shipped from the Company’s manufacturing or distribution facilities or when delivered to the customer’s named location. Sales tax, value-added tax, or other taxes collected concurrent with revenue producing activities are excluded from revenue. Freight costs billed to customers for shipping and handling activities are included in revenue with the related cost included in selling, general and administrative expenses. See Note 3 for further disclosures and detail regarding revenue recognition.
New Accounting Standards	Other Recently Adopted Accounting Standards In February 2018, the FASB issued ASU 2018-02 “Income Statement-Reporting Comprehensive Income.” ASU 2018-02 provides guidance on the reclassification of certain tax effects from the 2017 Tax Cuts and Jobs Act (“2017 Tax Act”) from accumulated other comprehensive income. Current generally accepted accounting principles requires deferred tax liabilities and deferred tax assets to be adjusted for the effect of a change in tax laws or tax rates, with that effect included in income from operations in the period of enactment. This included the income tax effects of items in accumulated other comprehensive income. This guidance allows a reclassification from accumulated other comprehensive income to retained earnings for the tax effects on items in accumulated other comprehensive income related to the change in tax rates from the 2017 Tax Act. This standard is effective for all entities for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Early adoption of this standard is permitted. The Company adopted this standard in the first quarter of 2018, and it did not have a material impact on the Company’s financial statements. In October 2016, the FASB issued ASU 2016-16 “Intra-Entity Transfers of Assets Other than Inventory.” ASU 2016-16 provides guidance on the timing of recognition of tax consequences of an intra-entity transfer of an asset other than inventory. The Company adopted the provision of this ASU during the first quarter of 2018, using the modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the quarter. The adoption of this guidance did not have a material impact on the Company’s financial statements. Accounting Standards Updates In August 2018, the FASB issued ASU 2018-15 “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40)-Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract.” ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance requires an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. The Company is currently evaluating the impact of this guidance on the Company’s financial statements, and does not expect the adoption of this guidance to have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-13 “Fair Value Measurement (Topic 820)-Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements under Topic 820. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. The Company is currently evaluating the impact of this guidance on the Company’s disclosures; however this guidance does not impact the Company’s financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016‑02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset for the lease term for both finance and operating leases with a term longer than twelve months. Topic 842 was subsequently amended by ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842,” ASU 2018-10, “Codification Improvements to Topic 842, Leases,” and ASU 2018-11 “Targeted Improvements.” ASU 2016-02 is effective for financial statements issued for annual periods beginning after December 15, 2018 and all interim periods thereafter. Early adoption is permitted for all entities. The Company plans to adopt this standard effective January 1, 2019. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company may choose to use either 1) the effective date of the standard or 2) the beginning of the earliest comparable period presented in the financial statements as the date of initial application. The Company expects to adopt the new standard on January 1, 2019 and use the effective date of the standard as the date of the Company’s initial application. By electing this approach, the financial information and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients throughout the transition. The Company expects to elect the “package of practical expedients,” which permits the Company to not reassess under the new standard the Company’s prior conclusions about lease identification, lease classification, and initial direct costs. The Company does not expect to elect the use-of-hindsight or the practical expedient pertaining to land easements, the latter not being applicable to the Company. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company expects to elect the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company will not recognize right-of-use assets or lease liabilities, and this includes not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also expects to elect the practical expedient not to separate lease and non-lease components for all of the Company’s leases. The Company is continuing to evaluate the new lease standard, and is in the process of designing the necessary changes to its existing processes and configuring system requirements that will be required to implement this new standard. The Company has a variety of categories of lease arrangements, including real estate, automobiles, manufacturing equipment, facility equipment, office equipment and certain service arrangements. The Company is currently reviewing its leasing arrangements in order to evaluate the impact of this standard on the Company’s financial statements. The Company does not expect a significant change in its leasing activity between now and adoption. The Company is unable to quantify the impact of adoption at this time. However, the Company expects the primary impact to its consolidated financial position upon adoption will be the recognition, on a discounted basis, of its minimum commitments under non-cancelable operating leases on its consolidated balance sheets resulting in the recording of right-of-use assets and lease obligations. The Company currently does not expect ASC 842 to have a material effect on either its consolidated statement of operations or consolidated statement of cash flow.
