Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of CommerceHub. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") for interim financial information. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments we consider to be necessary to give a fair presentation of our financial position, results of comprehensive income (loss) and cash flows, and changes in equity for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2016 consolidated balance sheet data was derived from our audited consolidated financial statements at that date. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained within our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the Securities and Exchange Commission (the "SEC") on March 7, 2017 (the "2016 Annual Report").

Use of Estimates

Preparing these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.

Segment and Geographic Information

Operating segments are components of our business for which discrete financial information is available and evaluated by the chief operating decision maker ("CODM") for purposes of allocating resources and evaluating financial performance. Our Chief Executive Officer, who is our CODM, reviews consolidated financial information results of the Company to allocate resources and evaluate performance. As such, the Company operates as a single segment.
