Basis of Accounting Presentation

The accompanying unaudited interim condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments that are necessary, which are of a normal and recurring nature, for a fair presentation for the periods presented of the financial position, results of operations and cash flows of the Company and its wholly-owned subsidiaries: IWN, Inc., IWN, L.P., Buzztime Entertainment, Inc., NTN Wireless Communications, Inc., NTN Software Solutions, Inc., NTN Canada, Inc., and NTN Buzztime, Ltd., all of which, other than NTN Canada, Inc., are dormant subsidiaries. All significant intercompany transactions have been eliminated in consolidation.

These condensed consolidated financial statements should be read with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2017. The accompanying condensed balance sheet as of December 31, 2017 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2018, or any other period.

In connection with preparing its financial statements as of and for the period ended June 30, 2018, the Company evaluated whether there are conditions and events, considered in the aggregate, that are known and reasonably knowable that would raise substantial doubt about its ability to continue as a going concern within twelve months after the date that such financial statements are issued. The Company believes it has sufficient cash to meet its operating cash requirements and to fulfill its debt obligations for at least the next twelve months after the date that such financial statements are issued. During the three months ended June 30, 2018, the Company issued 345,772 shares of its common stock in a registered direct offering and received net proceeds of approximately $1,381,000. (See Note 4.) To increase the likelihood that the Company will be able to successfully execute its operating and strategic plan and to position the Company to better take advantage of market opportunities for growth, it is continuing to evaluate additional financing alternatives, including additional equity financings and alternative sources of debt. If the Company’s cash and cash equivalents are not sufficient to meet future cash requirements, it may have to reduce planned capital expenses, reduce operational cash uses or raise capital on terms that are not as favorable to the Company as they otherwise might be.
