In addition to its U.S. operations, the Company also markets its products in over 50 international markets through the distribution channels of Alphatec Spine and its affiliate, Scient’x S.A.S., and its subsidiaries (“Scient’x”), via a direct sales force in Italy and the United Kingdom and via independent distributors in the rest of Europe, the Middle East and Africa.

In Asia, the Company markets its products through its subsidiary, Alphatec Pacific, Inc. and its subsidiaries (“Alphatec Pacific”), via a direct sales force and independent distributors, and through distributors in other parts of Asia and Australia. Basis of Presentation The accompanying condensed consolidated balance sheet as of December 31, 2014, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) related to a quarterly report on Form 10-Q. Certain information and note disclosures normally included in annual audited financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made in this quarterly report on Form 10-Q are adequate to make the information not misleading. The interim unaudited condensed consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the financial position and results of operations for the periods presented. All such adjustments are of a normal and recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2014, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 that was filed with the SEC on February 26, 2015. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015, or any other future periods. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. A going concern basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of its liabilities in the normal course of business. Based on the Company’s annual operating plan, management believes that its cash as of March 31, 2015 of $11.4 million combined with anticipated cash flow from operations through March 31, 2016 and other working capital, excluding common stock warrant liabilities, of $43.2 million at March 31, 2015 and the Company's available borrowings under the credit facilities with MidCap Financial, LLC ("MidCap") will be sufficient to fund its cash requirements through at least March 31, 2016. The Company’s amended and restated credit facility (the “Amended Credit Facility”) with MidCap contains financial covenants consisting of a monthly fixed charge coverage ratio, a senior leverage ratio and a total leverage ratio (see Note 5). Based on the Company’s current operating plan, the Company believes that it will be in compliance with the financial covenants of the Amended Credit Facility at least through March 31, 2016. However, there is no assurance that the Company will be able to do so. If the Company is not able to achieve its planned revenue or incurs costs in excess of its forecasts, it may be required to substantially reduce discretionary spending and it could be in default of the Amended Credit Facility. There can be no assurance that the Company could obtain a waiver of such default from MidCap, that the Amended Credit Facility could be successfully renegotiated or that the Company could modify its operations to maintain liquidity. If the Company is unable to obtain any required waiver or amendments, MidCap would have the right to exercise remedies specified in the Amended Credit Facility, including accelerating the repayment of debt obligations. The Company may be forced to seek additional financing, which may include additional debt and/or equity financing or funding through other third party agreements. There can be no assurances that additional financing would be available on acceptable terms or available at all. Furthermore, any equity financing may result in dilution to existing stockholders and any debt financing may involve agreements that include covenants limiting or restricting the Company's ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends.

The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. A going concern basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of its liabilities in the normal course of business.
