The Company and Basis of Presentation	The Company and Basis of Presentation The Company Alphatec Holdings, Inc. (“Alphatec”, “Alphatec Holdings” or the “Company”), through its wholly owned subsidiary, Alphatec Spine, Inc. and its subsidiaries (“Alphatec Spine”) designs, develops, manufactures and markets products for the surgical treatment of spine disorders. In addition to its U.S. operations, the Company also markets its products in over 50 international markets through its affiliate, Scient’x S.A.S. and its subsidiaries (“Scient’x”), via a direct salesforce in Italy and the United Kingdom and via independent distributors in the rest of Europe, the Middle East and Africa. In South America and Latin America the Company conducts its operations through its Brazilian subsidiary, Cibramed Productos Medicos. 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 consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and include the accounts of Alphatec and Alphatec Spine and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company has incurred significant net losses since inception and has relied on its ability to fund its operations through revenues from the sale of its products, equity financings and debt financings. As the Company has incurred losses, successful transition to profitability is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. This may not occur and, unless and until it does, the Company will continue to need to raise additional capital. Additionally, as discussed below, the Company has a significant amount of debt that is classified as current debt. These conditions raise substantial doubt about the Company's ability to continue as a going concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. 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. Operating losses and negative cash flows may continue for at least the next year as the Company continues to incur costs related to the execution of its operating plan, introduction of new products and expansion into new geographies. The Company's amended and restated credit facility (the "Amended Credit Facility") with MidCap Financial, LLC ("MidCap") matures in December 2016, which will require the Company to refinance the Amended Credit Facility with MidCap or to seek alternative financing. In addition, as disclosed in Note 5 as of December 31, 2015 the Company has determined that it failed to comply with the fixed charge coverage ratio covenant under its Amended Credit Facility with MidCap for June, August, September, October and December of 2015 and January 2016. The Company’s default under the MidCap credit facility also constitutes an event of default under the facility agreement (the "Facility Agreement") with Deerfield Private Design Fund II, L.P., Deerfield Private Design International II, L.P., Deerfield Special Situations Fund, L.P., and Deerfield Special Situations International Master Fund, L.P., (collectively "Deerfield"). In 2016, MidCap and Deerfield provided waivers of the Company’s failure to comply with the fixed charge coverage ratio covenant during such periods and MidCap and Deerfield has provided waivers of such defaults. The Company can provide no assurance that it will be in compliance with the financial covenants in the future. If the Company does not obtain waivers from MidCap or Deerfield, they would have the right to call the debts due immediately, which would significantly impact the Company's ability to continue as a going concern. Management intends to pursue additional opportunities to raise additional capital through public or private equity offerings, debt financings, receivables financings or collaborations or partnerships with other companies to further support its planned operations. However, there is no assurance that it will be able to do so.

Basis of Presentation

The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and include the accounts of Alphatec and Alphatec Spine and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The Company has incurred significant net losses since inception and has relied on its ability to fund its operations through revenues from the sale of its products, equity financings and debt financings. As the Company has incurred losses, successful transition to profitability is dependent upon achieving a level of revenues adequate to support the Company’s cost structure.

Additionally, as discussed below, the Company has a significant amount of debt that is classified as current debt. These conditions raise substantial doubt about the Company's ability to continue as a going concern.
