The Company currently markets the following system platforms: excel, enlighten, Juliet, Secret RF, truSculpt xeo . truSculpt iD truSculpt flex Juliet Secret RF third Titan, truSculpt 3D , truSculpt iD and truSculpt flex Headquartered in Brisbane, California, the Company operates wholly-owned subsidiaries in Australia, Belgium, Canada, France, Germany, Hong Kong, Japan, Spain, Switzerland and the United Kingdom. The Company’s wholly owned subsidiary in Italy is currently dormant. These active subsidiaries market, sell and service the Company’s products outside of the United States. The Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All inter-company transactions and balances have been eliminated. Unaudited Interim Financial Information In the opinion of the Company, the accompanying unaudited Condensed Consolidated Financial Statements included in this report reflect all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of its financial position as of June 30, 2019 2018, three six June 30, 2019 2018, six June 30, 2019 2018.

The Company uses the same accounting policies in preparing quarterly and annual financial statements. Unless otherwise noted, amounts presented within the Notes to Condensed Consolidated Financial Statements refer to the Company’s continuing operations. Notes 2 13 Use of Estimates The preparation of Condensed Consolidated Financial Statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the accompanying notes, and the reported amounts of revenue and expenses during the reported periods. Actual results could differ materially from those estimates. On an ongoing basis, management evaluates its estimates, including those related to warranty obligations, sales commission, accounts receivable and sales allowances, valuation of inventories, fair value of goodwill, useful lives of property and equipment, incremental borrowing rates related to the Company’s leases, assumptions regarding variables used in calculating the fair value of the Company's equity awards, expected achievement of performance based vesting criteria, management performance bonuses, fair value of investments, the standalone selling price of the Company's products and services, the customer life and period of benefit used to capitalize and amortize contracts acquisition costs, variable consideration, contingent liabilities, recoverability of deferred tax assets, and effective income tax rates. Management bases estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Risks and Uncertainties The Company's future results of operations involve a number of risks and uncertainties. Factors that could affect the Company's future operating results and cause actual results to vary materially from expectations include, but are not Recently Adopted Accounting Pronouncements Adopted In February 2016, 2016 02, 842 July 2018, 2018 11, 2016 02 2018 11 not July 2018, 2018 10, 842, 2016 02.
