The Company provides a leading cross-channel, cross-device, enterprise marketing software platform for search, social and display advertising channels, offered as a software-as-a-service, or SaaS, solution for advertisers and agencies. The Company’s platform enables digital marketers to improve financial performance, realize efficiencies and time savings, and make better business decisions. The Company’s corporate headquarters are located in San Francisco, California, and the Company has additional offices in the following locations: Austin, Chicago, Dublin, Hamburg, London, New York, Paris, Portland, Shanghai, Sydney and Tokyo.</p> <p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">References to “2017,” “2016” and “2015” shall mean the year ended December 31, 2017, the year ended December 31, 2016 and the year ended December 31, 2015, respectively. All amounts presented in these notes to the consolidated financial statements are in thousands, except where noted.</p></div>

The Company is subject to uncertainties such as the impact of future events, economic and political factors and changes in the Company’s business environment; therefore, actual results could differ from these estimates. Accordingly, the accounting estimates used in the preparation of the Company’s financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Changes in estimates are made when circumstances warrant. Such changes in estimates and refinements in estimation methodologies are reflected in reported results of operations and if material, the effects of changes in estimates are disclosed in the notes to the consolidated financial statements. Significant estimates and assumptions by management affect the allowances for doubtful accounts and customer credits, the carrying value of long-lived assets (including goodwill and intangible assets), the useful lives of long-lived assets, the accounting for income taxes, and stock-based compensation.</p></div>

The Company’s cash and cash equivalents are placed with high-credit-quality financial institutions and issuers, and at times exceed federally insured limits. The Company has not experienced any loss relating to cash and cash equivalents in these accounts. The Company performs periodic credit evaluations of its customers and generally does not require collateral.</p> <p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of December 31, 2017 and 2016, no single customer accounted for 10% or more of net accounts receivable.

The Company defers tenant improvement allowances and amortizes the balance as a reduction to rent expense over the lease term. The Company records rent holidays and rent escalations on a straight-line basis over the lease term. Deferred rent is included in accrued expenses and other current liabilities, as well as other long-term liabilities in the accompanying consolidated balance sheets.</p></div>

These overstated revenues had accumulated since the Company’s acquisition in June 2014 of NowSpots, Inc., which conducted business as Perfect Audience, and the out-of-period adjustment resulted in a decrease to revenues in the amount of $400 for the year ended December 31, 2017. Management determined that this adjustment was not material to the Company’s consolidated financial statements for the year ended December 31, 2017, nor to any previously issued consolidated financial statements.</p></div>
