New Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Pronouncements ASU 2018-05 In March 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-05, "Income Taxes (Topic 740)." ASU 2018-05 provides amendments to SEC paragraphs pursuant to Staff Accounting Bulletin ("SAB") No. 118 related to the accounting for the income tax effects of the Tax Cuts and Jobs Act ("TCJA") enacted as of December 22, 2017. ASU 2018-05 clarifies the income tax effects of the TCJA when accounting under Topic 740 is (1) complete, (2) incomplete, but for which a reasonable estimate can be determined, or (3) incomplete, but for which a reasonable estimate cannot be determined. The adoption of ASU 2018-05 as of the March 13, 2018 issuance date had no material impact on our financial position, results of operations or cash flows. With the adoption of ASU 2018-05 under the provisions of SAB 118, we made an effort to reasonably estimate the impact of the TCJA, however, we have not completed our accounting under Topic 740 as of June 30, 2018. ASU 2017-09 In May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718) - Scope in Modification Accounting." ASU 2017-09 provides clarity and reduces diversity in practice and cost and complexity when applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. An entity should account for the effects of a modification unless all of certain criteria are met. Those criteria relate to fair value, vesting conditions and classification of the modified award. If all three conditions are the same for the modified award as for the original award, then the entity should not account for the effects of the modification. ASU 2017-09 is effective for all entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Our adoption of ASU 2017-09 as of January 1, 2018 had no material impact on our financial position, results of operations or cash flows. ASU 2016-16 In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory." Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset is sold to an outside party. The amendments in ASU 2016-16 eliminate the exception for an intra-entity transfer of an asset other than inventory, and allows recognition of the income tax consequences when the transfer occurs. ASU 2016-16 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings. Our adoption of ASU 2016-16 as of January 1, 2018 had no material effect on our financial position, results of operations or cash flows. ASU 2016-15 In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments." The amendments in ASU 2016-15 are intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows, with the intent of reducing diversity in practice for the eight types of cash flows identified. ASU 2016-15 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017. Our adoption of ASU 2016-15 as of January 1, 2018 had no material effect on our financial position, results of operations or cash flows. ASU 2014-09 In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 replaces most existing revenue recognition guidance, and requires companies to recognize revenue based upon the transfer of promised goods and/or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and/or services. In addition, the standard requires disclosures related to the nature, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We applied the five-step method outlined in the ASU to all revenue streams and elected the full retrospective method for our adoption of the standard as of January 1, 2018. The additional disclosures required by the ASU are included in Note 2, Revenues. Recently Issued Pronouncements Not Yet Adopted ASU 2018-10 In July 2018, the FASB issued ASU 2018-10, "Codification Improvements to Topic 842, Leases." The amendments in ASU 2018-10 clarify, correct or remove inconsistencies in the guidance provided under ASU 2016-02 (see below) related to sixteen specific issues identified. ASU 2018-10 is effective for public companies' annual periods, and interim periods within those fiscal years, beginning after December 15, 2018, in accordance with Topic 842. We will be evaluating the potential impact of ASU 2018-10 to our company, however, as with other Topic 842 updates, we expect ASU 2018-10 to have a material impact on our financial position, results of operations and cash flows. Further, we also anticipate significant additional disclosure requirements associated with the new standard. ASU 2018-09 In July 2018, the FASB issued ASU 2018-09, "Codification Improvements." The FASB has a standing project to address suggestions received from stakeholders on the Accounting Standards Codification ("ASC" or "Codification") and to make other incremental improvements to GAAP. This perpetual project facilitates ASC updates for technical corrections, clarifications, and other minor improvements, and these amendments are referred to as Codification improvements. ASU 2018-09 includes amendments affecting a wide variety of topics and applies to all reporting entities within the scope of the affected accounting guidance. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in the ASU do not require transition guidance and are effective upon issuance of the ASU. However, many of the amendments in the ASU have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. While we do not expect the adoption of ASU 2018-09 to have a material effect on our business, we are evaluating the potential impact that the new ASU may have on our financial position, results of operations and cash flows. ASU 2018-07 In June 2018, the FASB issued ASU 2018-07, "Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting." ASU 2018-07 expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards with certain exceptions. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. Further, Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. ASU 2018-07 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. While we do not expect the adoption of ASU 2018-07 to have a material effect on our business, we are evaluating the potential impact that the new ASU may have on our financial position, results of operations and cash flows. ASU 2018-02 In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)." ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA, thereby eliminating the stranded tax effects and improving the usefulness of reported information to financial statement users. ASU 2018-02 is effective for all entities for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period, for public business entities for which financial statements have not yet been issued. While we do not expect the adoption of ASU 2018-02 to have a material effect on our business, we are evaluating the potential impact that ASU 2018-02 may have on our financial position, results of operations and cash flows. ASU 2017-12 In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 provides better alignment of an entity's risk management activities and financial reporting of hedges through changes to both the designation and measurement guidance for qualifying hedging relationships. In addition, the amendments in ASU 2017-12 also simplify the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements to increase the understandability of the results of an entity's intended hedging strategies. ASU 2017-12 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early application is permitted in any interim period after issuance of the new standard, with effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing as of the adoption date, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income and opening retaining earnings. Amended presentation and disclosure guidance is required only prospectively, and certain transition elections are available upon adoption. While we do not expect the adoption of ASU 2017-12 to have a material effect on our business, we are evaluating the potential impact that ASU 2017-12 may have on our financial position, results of operations and cash flows. ASU 2016-02 In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 replaces the existing guidance in Accounting Standards Codification ("ASC") 840, Leases. The new standard requires companies and other organizations to include lease obligations on their balance sheets, including a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use ("ROU") asset and a corresponding lease liability. For finance leases the lessee would recognize interest expense and amortization of the ROU asset, and for operating leases the lessee would recognize a straight-line total lease expense. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02, as amended, is effective for public companies' annual periods, and interim periods within those fiscal years, beginning after December 15, 2018. We are currently assessing the impact that ASU 2016-02 will have on our consolidated financial statements, and expect that the primary impact upon adoption will be the recognition, on a discounted basis, of our minimum commitments under non-cancellable operating leases on our consolidated balance sheets, resulting in the recording of ROU assets and lease liabilities, as well as additional disclosures. Based on initial high-level assessments of our main facilities leases related to our domestic operations, we expect ASU 2016-02 to have a material impact on our financial position, results of operations and cash flows. Further, analysis of our leases population is still in progress. We also anticipate significant additional disclosure requirements associated with the new standard.
Revenue Recognition	Exemptions and Elections We apply the practical expedient as per ASC 606-10-50-14 and do not disclose information related to remaining performance obligations due to their original expected durations are one year or less. We expense sales commissions when incurred because the amortization period would have been less than one year. These costs are recorded in selling and marketing expense. We generally account for our shipping and handling activities as a fulfillment activity, consistent with the timing of revenue recognition; that is, when our customer takes control of the transferred goods. In the event that a customer were to take control of a product prior to shipment, we make an accounting policy election to treat such shipping and handling activities as a fulfillment cost.Revenue Recognition Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our product sales and shipping revenues are reported net of promotional discounts, returns allowances, contractual rebates, and consideration payable to our customers. We estimate the revenue impact of retail sales incentive programs based on the planned duration of the program and historical experience. If the amount of sales incentives is reasonably estimable, the impact of such incentives is recorded at the later of the time the customer is notified of the sales incentive or the time of the sale. We estimate our liability for product returns based on historical experience, and record the expected customer refund liability as a reduction of revenue, and the expected inventory right of recovery, net of estimated scrap, as a reduction of cost of sales. If actual return costs differ from previous estimates, the amount of the liability and corresponding revenue are adjusted in the period in which such costs occur. We provide standard assurance-type warranties on our products which cover defective materials or nonconforming products, and is included with each product at no additional charge. In addition, we offer service-type/extended warranties for an additional fee to our Direct channel customers and Retail specialty and commercial customers. These warranty contracts provide coverage on labor and parts beyond the standard assurance warranty period. For our product sales, services, and freight and delivery fees, we are the principal in the contract and recognize revenue at a point in time. For our Direct channel extended warranty contracts, we are the agent and recognize revenue on a net basis because our performance obligation is to facilitate the arrangement between our customers and the third-party performance obligor. For customer contracts that include multiple performance obligations, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling price based on prices charged to customers or using expected cost plus margin.

In March 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-05, "Income Taxes (Topic 740)." ASU 2018-05 provides amendments to SEC paragraphs pursuant to Staff Accounting Bulletin ("SAB") No. 118 related to the accounting for the income tax effects of the Tax Cuts and Jobs Act ("TCJA") enacted as of December 22, 2017. ASU 2018-05 clarifies the income tax effects of the TCJA when accounting under Topic 740 is (1) complete, (2) incomplete, but for which a reasonable estimate can be determined, or (3) incomplete, but for which a reasonable estimate cannot be determined. The adoption of ASU 2018-05 as of the March 13, 2018 issuance date had no material impact on our financial position, results of operations or cash flows. With the adoption of ASU 2018-05 under the provisions of SAB 118, we made an effort to reasonably estimate the impact of the TCJA, however, we have not completed our accounting under Topic 740 as of June 30, 2018.

In May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718) - Scope in Modification Accounting." ASU 2017-09 provides clarity and reduces diversity in practice and cost and complexity when applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. An entity should account for the effects of a modification unless all of certain criteria are met. Those criteria relate to fair value, vesting conditions and classification of the modified award. If all three conditions are the same for the modified award as for the original award, then the entity should not account for the effects of the modification. ASU 2017-09 is effective for all entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Our adoption of ASU 2017-09 as of January 1, 2018 had no material impact on our financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory." Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset is sold to an outside party. The amendments in ASU 2016-16 eliminate the exception for an intra-entity transfer of an asset other than inventory, and allows recognition of the income tax consequences when the transfer occurs. ASU 2016-16 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings.

We applied the five-step method outlined in the ASU to all revenue streams and elected the full retrospective method for our adoption of the standard as of January 1, 2018. The additional disclosures required by the ASU are included in Note 2, Revenues.

In July 2018, the FASB issued ASU 2018-10, "Codification Improvements to Topic 842, Leases." The amendments in ASU 2018-10 clarify, correct or remove inconsistencies in the guidance provided under ASU 2016-02 (see below) related to sixteen specific issues identified. ASU 2018-10 is effective for public companies' annual periods, and interim periods within those fiscal years, beginning after December 15, 2018, in accordance with Topic 842. We will be evaluating the potential impact of ASU 2018-10 to our company, however, as with other Topic 842 updates, we expect ASU 2018-10 to have a material impact on our financial position, results of operations and cash flows. Further, we also anticipate significant additional disclosure requirements associated with the new standard.

In July 2018, the FASB issued ASU 2018-09, "Codification Improvements." The FASB has a standing project to address suggestions received from stakeholders on the Accounting Standards Codification ("ASC" or "Codification") and to make other incremental improvements to GAAP. This perpetual project facilitates ASC updates for technical corrections, clarifications, and other minor improvements, and these amendments are referred to as Codification improvements. ASU 2018-09 includes amendments affecting a wide variety of topics and applies to all reporting entities within the scope of the affected accounting guidance. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in the ASU do not require transition guidance and are effective upon issuance of the ASU. However, many of the amendments in the ASU have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. While we do not expect the adoption of ASU 2018-09 to have a material effect on our business, we are evaluating the potential impact that the new ASU may have on our financial position, results of operations and cash flows.

In June 2018, the FASB issued ASU 2018-07, "Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting." ASU 2018-07 expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees.

ASU 2018-07 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. While we do not expect the adoption of ASU

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)." ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA, thereby eliminating the stranded tax effects and improving the usefulness of reported information to financial statement users. ASU 2018-02 is effective for all entities for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period, for public business entities for which financial statements have not yet been issued.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 provides better alignment of an entity's risk management activities and financial reporting of hedges through changes to both the designation and measurement guidance for qualifying hedging relationships. In addition, the amendments in ASU 2017-12 also simplify the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements to increase the understandability of the results of an entity's intended hedging strategies. ASU 2017-12 is effective for public companies' fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. Early application is permitted in any interim period after issuance of the new standard, with effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing as of the adoption date, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income and opening retaining earnings. Amended presentation and disclosure guidance is required only prospectively, and certain transition elections are available upon adoption. While we do not expect the adoption of ASU 2017-12 to have a material effect on our business, we are evaluating the potential impact that ASU 2017-12 may have on our financial position, results of operations and cash flows.
