Our corporate headquarters and Americas’ sales office are located in Plano, Texas and Milpitas, California. Design, marketing, and engineering centers are located in Plano; Milpitas; Taipei, Taoyuan City and Zhubei City, Taiwan; Manchester, England; and Neuhaus, Germany. Our wafer fabrication facilities are located in Manchester and in Shanghai, China. We have assembly and test facilities located in Shanghai, Jinan, Chengdu, and Yangzhou, China, as well as in Hong Kong, Neuhaus and Taipei. Additional engineering, sales, warehouse, and logistics offices are located in Taipei; Hong Kong; Manchester; Shanghai; Shenzhen, China; Seongnam-si, South Korea; and Munich, Germany, with support offices throughout the world. Basis of Presentation The condensed consolidated financial data at December 31, 2017 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”) on February 20, 2018 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2018. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances have been reclassified to conform to the current financial statement presentation. Recently Issued Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact on the Company’s financial statements: ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) - On January 1, 2018, we adopted the comprehensive new revenue recognition standard issued by the FASB. This standard is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard sets forth a five-step revenue recognition model which replaces the previous revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance. The adoption of this standard did not have a material impact on our condensed consolidated financial position, reported revenue, results of operations or cash flows as of and for the three months ended March 31, 2018. See Note 7 for our expanded revenue disclosures required by the new standard. ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”) - In February 2016, the FASB issued ASU 2016-02, which amends the accounting treatment for leases. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU 2016-02 may have on its consolidated financial statements and has not elected early adoption as of the period ended March 31, 2018. During the second quarter of 2017 we engaged outside accounting consultants to assist us in the implementation of this new standard. ASU No. 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments – In November 2016, the FASB issued guidance on the presentation of restricted cash which requires that on the statement of cash flows, amounts generally described as restricted cash or restricted cash equivalents should be included within the beginning and ending balances of cash and cash equivalents. We adopted this guidance in the first quarter of 2018 on a retrospective basis. As a result, restricted cash amounts that have historically been included in prepaid expenses on our consolidated balance sheets are now included with cash and cash equivalents on the consolidated statements of cash flows. As of March 31, 2018 and December 31, 2017 we had restricted cash of $1.4 million. Restricted cash is pledged as collateral when we enter into agreements with banks for certain banking facilities.
