Organization Consolidation And Presentation Of Financial Statements [Abstract]

The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as well as the instructions to Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), for interim reporting. Accordingly, the Company has condensed or omitted certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP. All intercompany accounts and transactions have been eliminated in consolidation.

The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of stockholders’ equity and the statements of cash flows for the interim periods but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2020 or any future period.

These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on February 24, 2020 (the “Annual Report”).

Use of Estimates

The preparation of consolidated financial statements in conformity with 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 revenue and expenses during the reporting period. Management periodically evaluates such estimates and assumptions for continued reasonableness. In particular, we make estimates with respect to the fair value allocation of multiple performance obligation in revenue recognition, the valuation allowance based on expected credit losses and the collectability of accounts receivable, valuation and estimated useful lives of long-lived assets, fair value of the liability and equity components of the Notes (as defined below), stock-based compensation expense and income taxes. Appropriate adjustments, if any, to the estimates used are made prospectively based upon periodic evaluation. Actual results could differ from those estimates.

Concentration of Credit and Other Risks

Concentration of Credit Risk and Other Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company maintains its cash in bank deposit accounts that, at times, may exceed federally insured limits. As of March 31, 2020 and December 31, 2019, no single customer represented more than 10% of the balance in accounts receivable. Management considers concentration of credit risk to be minimal with respect to accounts receivable due to the positive historical collection experience of the Company. No single customer represented more than 10% of revenue for the three months ended March 31, 2020 or 2019. The Company does not experience concentration of credit risk in foreign countries as no single foreign country represents more than 10% of the Company’s consolidated revenues or net assets.

Significant Accounting Policies

The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes in the Annual Report, most notably Note 2 “Summary of Significant Accounting Policies”. Except for the adoption of ASU 2016-13 described below, there have been no changes to our significant accounting policies described in our Annual Report that have had a material impact on our consolidated condensed financial statements and related notes.
