Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Basis of Presentation	The Company and Basis of Presentation The Company Arlo Technologies, Inc. (“Arlo” or the “Company”) combines an intelligent cloud infrastructure and mobile app with a variety of smart connected devices that transform the way people experience the connected lifestyle. Its cloud-based platform creates a seamless, end-to-end connected lifestyle solution that provides users visibility, insight and a powerful means to help protect and connect with the people and things that matter most to them. Arlo enables users to monitor their environments and engage in real-time with their families and businesses from any location with a Wi-Fi or a cellular network internet connection. The Company conducts business across three geographic regions - Americas; Europe, Middle-East and Africa (“EMEA”); and Asia Pacific (“APAC”) - and primarily generates revenue by selling devices through retail channels, wholesale distribution and wireless carrier channels and paid subscription services through in-app purchases. On February 6, 2018, NETGEAR Inc. (“NETGEAR”) announced that its board of directors had unanimously approved the pursuit of a separation of its Arlo business from NETGEAR (the “Separation”) to be effected through an initial public offering (the “IPO”) of newly issued shares of the common stock of Arlo, then a wholly owned subsidiary of NETGEAR. On July 6, 2018, the Company filed a registration statement (as amended, the “IPO Registration Statement”) relating to the IPO of common stock of Arlo with the U.S. Securities and Exchange Commission (the “SEC”). Following a series of restructuring steps prior to the completion of the IPO of Arlo common stock, the Arlo business was transferred from NETGEAR to Arlo (collectively, the “Contribution”). On August 2, 2018, NETGEAR and Arlo announced the pricing of the IPO of 10,215,000 shares of Arlo’s common stock at a price to the public of $16.00 per share. On August 3, 2018, Arlo’s shares began trading on the New York Stock Exchange under the ticker symbol “ARLO.” On August 7, 2018, the Company completed its IPO of 11,747,250 shares of common stock (including 1,532,250 shares of common stock pursuant to the underwriters’ option to purchase additional shares, which was exercised in full on August 3, 2018), at $16.00 per share, before underwriting discounts and commissions and estimated offering costs. Cash proceeds from the IPO were $173.4 million, net of the portion of the offering cost paid by Arlo, which portion was $1.4 million. The total offering cost was $4.6 million, of which $3.2 million was paid by NETGEAR. Prior to the completion of the IPO, the Company was a wholly owned subsidiary of NETGEAR and upon the closing of the IPO (including the issuance of additional shares of common stock pursuant to the underwriters’ option to purchase additional shares, which was exercised in full) on August 7, 2018, NETGEAR owned approximately 84.2% of the shares of Arlo’s outstanding common stock. On November 29, 2018, NETGEAR announced that its board of directors had approved a special stock dividend (the “Distribution”) to NETGEAR stockholders of the 62,500,000 shares of Arlo common stock owned by NETGEAR. The Distribution was made on December 31, 2018 (the “Distribution Date”) to all NETGEAR stockholders of record as of the close of business on December 17, 2018 (the “Record Date”). In the Distribution, each NETGEAR stockholder of record on the Record Date received 1.980295 shares of Arlo common stock for every share of NETGEAR common stock held on the Record Date, subject to cash in lieu of fractional shares. The Distribution was intended to qualify as generally tax free to NETGEAR stockholders for U.S. federal income tax purposes. In connection with the Distribution, 62,500,000 shares of Arlo common stock held by NETGEAR were distributed to its stockholders and NETGEAR is no longer considered a related party to the Company. Basis of Presentation The unaudited condensed combined financial statements of Arlo that cover periods ending or as of dates prior to the completion of the IPO have been derived and carved out from the consolidated financial statements and accounting records of NETGEAR as if Arlo had operated on a stand-alone basis within the periods presented. In connection with the Separation and IPO, certain assets and liabilities presented have been transferred to Arlo at carry-over (historical cost) basis. Balances contributed by NETGEAR on or before the completion of the IPO were based on the master separation agreement between the Company and NETGEAR and related documents governing the Contribution. Following the completion of the IPO, the unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All periods presented have been accounted for in conformity with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the notes to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for fair statement of the unaudited condensed consolidated financial statements for interim periods. The Company has evaluated all subsequent events through the date the financial statements were issued. Reclassification Certain reclassifications have been made to the prior year’s condensed consolidated balance sheets and statements of cash flows to conform to the current year’s presentation. The reclassifications had no effect on the prior year’s condensed consolidated statements of operations, statements of comprehensive income (loss) and statements of stockholders’ equity. Allocated Expenses from NETGEAR Prior to the completion of the IPO, NETGEAR provided certain corporate services to the Company, which were allocated based on revenue, headcount, or other measures the Company has determined as reasonable through July 1, 2018. The amount of these allocations from NETGEAR reflected within operating expenses in the unaudited condensed consolidated statements of operations was $30.6 million for the six months ended July 1, 2018, which included $9.4 million for research and development, $10.0 million for sales and marketing, and $11.2 million for general and administrative expense. There were no allocations from NETGEAR during the three months ended September 30, 2018. Following July 1, 2018, the Company assumed responsibility for the costs of these functions. Fiscal periods The Company’s fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a fiscal quarter basis rather than on a calendar quarter basis. Under the fiscal quarter basis, each of the first three fiscal quarters ends on the Sunday closest to the calendar quarter end, with the fourth quarter ending on December 31. Use of estimates The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. GAAP 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 reported periods. Management bases its estimates on various assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ materially from those estimates and operating results for the nine months ended September 29, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any future period.
