| The unaudited condensed financial statements included herein have been prepared by Zap.Com Corporation (“Zap.Com” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of such information. All such adjustments are of a normal recurring nature. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including a description of significant accounting policies normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), have been condensed or omitted pursuant to such rules and regulations. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. These interim financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 31, 2014. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results for any subsequent periods or the entire fiscal year ending December 31, 2014. |

| Since its inception, the Company has utilized the services of the management and staff of Harbinger Group Inc. (the Company’s “Principal Stockholder”), under a shared services agreement that allocated these costs on a percentage of time basis. The Company also shares office space with its Principal Stockholder under such agreement. Through June 30, 2014, the Principal Stockholder has waived its rights under the shared services agreement to be reimbursed for these costs. The Company recorded approximately $10,519 and $9,194 as contributed capital for such services for the three months ended June 30, 2014 and 2013, respectively and approximately $21,024 and $18,389 for the six months ended June 30, 2014 and 2013, respectively. The Company believes these allocations were made on a reasonable basis; however, they do not necessarily represent the costs that would have been incurred by the Company on a stand-alone basis. |
